Answer: Explanation: Cellular respiration is the chemical reaction in which glucose and oxygen are turned into water, carbon dioxide, and energy (ATP). ... C 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP is the complete balanced chemical formula for cellular respiration.

Explanation:

Answer:

cellular respiration is the process of extracting energy and is explained in 3 steps.  

first step: the glucose is broken down in the cytoplasm, which is called glycolysis

second step: the pyruvate molecules are then transported into the mitochondria, the "powerhouse" of the cell

third step: The molecules are transformed chemically when it enters an electron transport chain. This allows the molecules to be turned into ATP.  

Once you know this, the chemical reaction is one molecule of glucose (C6H12O6) and six molecules of oxygen (O2) yields six molecules of carbon dioxide (CO2) and six molecules of water (H2O).

C6H12O6 + 6O2 → 6CO2 + 6H2O

this creates ATP

Explanation:

Of the organisms provided, we have two animals and a plant, so if we see it as locomotion capacity only anteater and dolphin would be correct. Now if we are more specific and just took movement as the capacity to move even small parts, a plant can also be considered, we must remember that even when plants are sessile organisms, they grow and seek light, thus they can move although we are not capable of seeing it.

Option C.  a balance and a beaker are the instruments used to measure the density of seawater.

Density is defined as the mass of an object divided by its volume. Measuring the density of seawater is critical to oceanography since the density of seawater varies based on salinity and temperature, both of which have significant implications for ocean circulation, marine organisms, and weather systems. The pair of laboratory instruments that a student would use to measure the density of seawater is a balance and a beaker.

The mass of seawater is measured using the balance, while the volume is measured using the beaker. Let's learn more about the measurement of density: Measurement of Density: To determine the density of an object or substance, we must first calculate its mass and volume using laboratory instruments such as a balance and a beaker. The mass of an object is the amount of matter it contains, which is measured in grams. A balance is a tool used to measure mass. The volume of an object is the amount of space it occupies, which is measured in liters.

A beaker or a graduated cylinder is used to measure volume. The density is obtained by dividing the mass by the volume. To determine the density of seawater, a student can collect a sample of seawater and place it in a beaker. The mass of the seawater sample is measured using a balance. The volume of the seawater is calculated by measuring the volume of the beaker before and after adding the seawater and subtracting the initial volume from the final volume. The student then calculates the density of the seawater by dividing the mass of the seawater by its volume.

In conclusion, a balance and a beaker are the instruments used to measure the density of seawater. Therefore the correct option is C

Answer:

The environment selects the lineage which better fits their specializations in the available resources.

Explanation:

The possible motive that lineages demonstrated quickly diversification might happen because the environment contained the opportunities which the lineages took as an opportunity to evolve. The environment could have benefited some species rather than others which could lead to different specializations of different lineages. For example, after the downfall of the dominance of dinosaurs, mammals had a few new environments to evolve with new resources, this led to more lineage biodiversification.

Human population growth and its associated impacts are currently decreasing levels of biodiversity. As human populations grow, they require more resources and land, which leads to habitat destruction, fragmentation, and degradation. This has a significant impact on wildlife populations and their ability to survive. As species disappear, ecosystems become less resilient and more vulnerable to collapse. Therefore, conservation efforts are necessary to protect biodiversity and prevent further losses.

Mitosis and meiosis are two different kinds of cell cycle reproduction. They have many things in common together, such as being an asexual form of reproduction. Mitosis produces body cells, identical daughter cells that can grow an organism and replace old/dead cells. Meiosis on the other hand makes gametes; or reproductive cells. When mitosis happens, it goes through stage of the mitotic phase known as PMAT. PMAT stands for: prophase, metaphase, anaphase, and telophase; followed by cytokinesis. Meiosis on the other hand, goes through PMAT twice. After mitosis, the product is 2 identical cells, which are used to replace cells or to grow. After meiosis, 4 NON-identical cells are made, which contain HALF the set of chromosomes; hence being called a haploid cell.

Mitosis has only one round of cell division, while meiosis has two. Mitosis only occurs in body cells, while meiosis occurs in sex cells. Mitosis produces daughter cells, that are identical to the parent cell, while mitosis produces haploid/diploid cells that only have half of the normal number of chromosomes.

Based on the information, we can infer that the measurement that could be the least probable is caudal peduncie depth strandard error. Also, the trend is for lake values to be higher than river values.

To identify the values we must analyze the table and identify they are not the trends. In this case we can infer that the tendency is for the values of the lake to be higher than the values of the river because all the values of the lake are higher than those of the river.

On the other hand, we can infer that the value that could be the least successful is the peduncie depth strandard error because it shows equal values. However, if we take into account the previous values, it should not be the same in both cases.

No single animal model can reproduce all of the human features of both acute and chronic lung diseases. However, the rabbit is a reliable model and clinically relevant facsimile of human disease. The similarities between rabbits and humans in terms of airway anatomy and responses to inflammatory mediators highlight the value of this species in the investigation of lung disease pathophysiology and in the development of therapeutic agents. The inflammatory responses shown by the rabbit model, especially in the case of asthma, are comparable with those that occur in humans. The allergic rabbit model has been used extensively in drug screening tests, and this model and humans appear to be sensitive to similar drugs. In addition, recent studies have shown that the rabbit serves as a good platform for cell delivery for the purpose of stem-cell-based therapy.

The characteristic used to determine a banana's relationship to other plants is its morphology or physical characteristics.

What is morphology?

Morphology is the study of the form and structure of living organisms, including their physical and anatomical features. In biology, morphology is used to describe the appearance, shape, and size of different parts of an organism, such as its organs, tissues, cells, and even its molecules. This includes the study of external and internal structures, as well as their function, development, and evolution. Morphological characteristics are often used in the classification and identification of different species, as they can provide important clues about an organism's evolutionary history, ecological niche, and relationship to other organisms.

We assume you are referring to the scientific classification of bananas in the plant kingdom. In this case, the characteristic used to determine a banana's relationship to other plants is its morphology or physical characteristics. Bananas belong to the genus Musa, which is part of the family Musaceae.

The characteristics used to classify plants into different taxonomic groups include their structural features, such as their leaves, stems, flowers, and fruit, as well as their genetic and evolutionary relationships. These characteristics are used to group plants into increasingly broader taxonomic categories, from species to genus, family, order, class, phylum, and kingdom.

b. A second marker in the knock-out cassette, that if inserted into the genome results in cell death when plated on selective media.

Explanation:

General recombination, also known as homologous recombination, refers to the naturally occurring process of exchange of genetic material between pairs of homologous DNA sequences. This process (homologous recombination) can be exploited by genetic engineering to insert DNA segments of interest at target genes. Moreover, a cassette is a mobile DNA segment containing almost a gene and a recombination site, which is integrated into the locus/loci of interest by homologous recombination. A cassette may contain a DNA segment called 'negative marker' which prevents growth under particular conditions, while a positive marker permits growth under certain conditions. In consequence, a second marker consisting of a drug cassette may be used as a negative marker in order to evidence its insertion by inducing cell death when they are plated in selective conditions.

Answer:

NAD+ (nicotinamide adenine dinucleotide) is indeed crucial for ATP production, even in anaerobic pathways such as glycolysis followed by fermentation. Allow me to explain the significance of NAD+ and its role in ATP production.

During glycolysis, glucose is broken down into pyruvate, producing a small amount of ATP and NADH. The conversion of NAD+ to NADH occurs during the oxidation of certain molecules, including glucose, in the pathway. This conversion is essential because NADH carries high-energy electrons that can be used in subsequent steps to generate more ATP.

In aerobic respiration, NADH is further utilized in the electron transport chain (ETC) within the mitochondria. The ETC transfers electrons from NADH to oxygen, generating a significant amount of ATP through oxidative phosphorylation. However, in anaerobic conditions where oxygen is limited, like during fermentation, the ETC cannot function.

Here's where NAD+ becomes critical. In order to keep glycolysis running and continue generating ATP, the NADH produced during glycolysis must be converted back to NAD+. This allows glycolysis to continue producing ATP, even without the presence of oxygen. Without a mechanism to regenerate NAD+, glycolysis would halt due to a lack of NAD+, leading to a severe reduction in ATP production.

Fermentation pathways differ depending on the organism, but they all involve the regeneration of NAD+. For example, in lactic acid fermentation, pyruvate is converted into lactate, which involves the transfer of electrons from NADH to pyruvate, regenerating NAD+. Similarly, in alcoholic fermentation, pyruvate is converted into ethanol, again regenerating NAD+.

In summary, NAD+ is essential in anaerobic ATP production because it serves as a coenzyme that accepts electrons and facilitates the conversion of NADH back to NAD+. By regenerating NAD+, cells can sustain glycolysis and continue producing ATP, even in the absence of oxygen.

Varicella Zoster is an infectious viral disease causing chickenpox in children and shingles in grown-ups. Inoculation plays a crucial part in avoidance and lessening complications.

Women and noblemen,

Nowadays, I would like to examine a vital and predominant viral disease known as Varicella Zoster. Varicella Zoster, commonly alluded to as chickenpox, is caused by a varicella-zoster infection. It fundamentally influences children, but can too affect grown-ups who have not been already contaminated.

Varicella Zoster presents as a profoundly infectious sickness characterized by a particular hasty, fever, and common disquietude. The infection spreads through coordinated contact or respiratory beads, making it effortlessly transmissible inside families and communities.

Whereas chickenpox is for the most part a gentle ailment in children, it can lead to more serious complications in grown-ups, pregnant ladies, and people with debilitated resistant frameworks. These complications incorporate pneumonia, bacterial contaminations, and in uncommon cases, neurological complications such as encephalitis.

Luckily, the improvement of a profoundly successful antibody has essentially diminished the frequency of Varicella Zoster around the world. Immunization not as it were secures people from the distress and potential complications of chickenpox, but too makes a difference anticipate the infection from spreading inside the community.

In any case, Varicella Zoster doesn't halt at chickenpox. Once the introductory contamination settles, the infection remains torpid inside the body and can reactivate a long time afterward, causing a condition known as herpes zoster, or more commonly, shingles.

Shingles are characterized by a difficult hasty that ordinarily happens in a single dermatome, regularly along the middle or confront. The reactivated infection can cause critical pain and inconvenience, enduring for weeks or indeed months. Moreover, complications such as postherpetic neuralgia, a persistent torment disorder, can happen, especially in more seasoned people.

To combat the chance of shingles, an isolated antibody called the shingles antibody or herpes zoster immunization has been created. This antibody not as it were makes a difference anticipate shingles but moreover diminishes the chance of postherpetic neuralgia.

In conclusion, Varicella Zoster, enveloping both chickenpox and shingles, could be a viral contamination that has critical suggestions for open well-being. We have made significant progress in reducing the burden of this disease through extensive vaccination efforts.

In any case, ongoing efforts to prevent Varicella zoster from returning to our communities and to protect powerless populations require prompt attention and vaccination.

Much obliged to you for your thought. Let's collaborate to ensure a better future for everyone.
