The answer is B. Here is proof. Plz mark brainliest

Explanation:

Answer:

A. 345,6 mL

Explanation:

Tenemos un gas definido en ciertas condiciones (de presión, temperatura y volumen) y queremos saber el volumen que ocupará en condiciones normales de presión y temperatura, es decir, 1 atm y 0ºC.

Para resolver este problema utilizaremos la ecuación de los gases ideales:

pV=nRT

Ya tenemos todos los datos, y sólo nos resta calcular n, el número de moles. R es la constante de los gases, la cual tiene el valor redondeado de 0.082 L.atm/mol.K, por lo cual es importante convertir las unidades para que éstas se cancelen y den como resultado los moles de gas.

Dividimos 560 en 760 para pasar de mmHg a atm, 500 mL se dividen por 1000mL para pasar a litros, y a la temperatura de 18ºC se le suman 273 para pasarla a Kelvin.

Despejamos n de la ecuación:

n=p.V ÷ R.T

n= 0.740 atm × 0.50 L ÷ 0.082 L.atm/mol.K × 291 K

n= 0.0155 mol

Ahora que tenemos el número de moles del gas, podemos usar la ecuación nuevamente para calcular el volumen que tendrá el gas en condiciones normales (1 atm y 0ºC, o 273 K).

Despejamos V de la ecuación:

V= n.R.T ÷ p

V= 0.0155 mol × 0.082 L.atm/mol.K × 273 K ÷ 1 atm

V= 0.346 L ≈ 346 mL

El volumen que ocupará el mismo gas a condiciones normales será 346 mL, por ende la respuesta correcta es la A. Hay una pequeña discrepancia pero ésta es normal, se debe al redondeo del resultado al final (acá redondeo 345.6 a 346).

Solution:

The four types of chromosomal structural abnormalities can be grouped into the following two groups:

Balanced structural anomalies:

1. Translocations: simple or complex movement of chromosome fragments or whole chromosomes. Chromosome breaks and a part of it is attached to a different chromosome.

2. Inversion: where the chromosomal region is flipped so that it points in the opposite direction. That is, part of a chromosome breaks off at two points and the segment in between turns upside down and then rejoins the same chromosome.

Unbalanced structural anomalies:

3. Duplication: where part of a chromosome is copied. This means that a part of the chromosome is duplicated or has two copies. The result is additional chromosomal material.

4. Deletion: where part of a chromosome is removed. That is, there is DNA loss.

Explanation:

1. they are curious about how they get blind

2. the quills

Answer:

1.The first hypothesis is that blindness gives the tetra some sort of evolutionary advantage. That advantage might be the result of pleiotropy, which is when multiple effects are caused by the same mutation in one gene. Scientists think that the mutation that causes blindness in the tetra might also cause a "seemingly unrelated change in the fish that is beneficial."

2. Another effect it might have is to improve cave tetras' sense of smell.

Explanation:

A hydrogen bond is when positive and negative hydrogen forms together; this explains why cohesion sticks molecules together . Because of cohesion, the water molecules stick together and form a surface; this property is responsible for surface tension. Adhesion is the ability for water to stick to other substances; this helps with capillary action. Hydrogen bonding also explains why water's boiling point is higher than some liquid . With this, water has a high specific heat; this is because the water takes a lot of energy to raise (or lower) the temperature. Once again, hydrogen bonding is essential to another property. This property causes water to expand and to have a low density when frozen.

The statement regarding p53 that is not true is: "p53 promotes cell survival and growth regardless of cellular stress or DNA damage."

In fact, p53 is a tumor suppressor protein that plays a crucial role in preventing cancer by stopping cell growth and inducing apoptosis (cell death) in response to cellular stress or DNA damage.

Apoptosis, also known as programmed cell death, is a natural process of cell self-destruction that plays a crucial role in various physiological and pathological events in multicellular organisms. It is a tightly regulated and highly organized process that helps maintain tissue homeostasis, eliminate damaged or unwanted cells, and shape development.

Apoptosis involves a series of cellular events orchestrated by specific signaling pathways. These pathways can be activated by various internal and external stimuli, such as DNA damage, cellular stress, developmental cues, or immune responses. The activation of apoptotic pathways leads to the activation of specific enzymes called caspases, which are responsible for executing the cellular demolition process.

During apoptosis, cells undergo characteristic morphological changes, including cell shrinkage, membrane blebbing, chromatin condensation, and fragmentation of the cell into membrane-bound apoptotic bodies. Importantly, these changes prevent the release of harmful cellular contents and stimulate phagocytic cells to engulf and remove the apoptotic bodies, preventing inflammation and tissue damage.

Apoptosis serves several important functions in different contexts. During development, it plays a critical role in sculpting and shaping tissues and organs by eliminating excessive or unnecessary cells. In the immune system, apoptosis helps regulate the number of immune cells, eliminating autoreactive or infected cells. It is also involved in eliminating damaged or potentially cancerous cells, acting as a protective mechanism against tumor formation.

Apoptosis is a fundamental biological process that maintains tissue homeostasis, shapes development, and eliminates unwanted or damaged cells. Its highly regulated nature ensures that cells undergo self-destruction without causing harm to the surrounding tissues. Understanding the mechanisms and regulation of apoptosis is crucial for various fields, including developmental biology, immunology, and cancer research.

Nuclear power plant does not provide air pollution, noise pollution or either light pollution.Nuclear power plant is the heat source of the nuclear sector that can provide electricity to certain areas.

The cell won’t be able to completely oxidise glucose if an additive molecule that hinders the electron transport chain is applied. As a result, less oxygen is consumed.

When complex I is inhibited by antimycin A, electron transport from complexes or flavoproteins containing FADH2 to cytochromes is prevented.In this instance, the initial Complex Ill constituents are completely reduced and the subsequent constituents are oxidised. The final complex of eukaryotic oxidative phosphorylation in mitochondria is called cytochrome c oxidase. This process combines the reduction of electron carriers during metabolism with the reduction of molecular oxygen to water as well as the transfer of protons from the inner matrix of the mitochondria to the intermembrane gap.Adenosine triphosphate, an energy-carrying molecule, is present in the cells of all living things (ATP). ATP stores the chemical energy produced by the disintegration of food molecules before releasing it to drive other cellular processes.Cells often require chemical energy for three types of tasks: driving metabolic activities that wouldn’t occur naturally; transferring required materials across membranes; and doing mechanical work, like flexing muscles.

Water table, also called groundwater table, upper level of an underground surface in which the soil or rocks are permanently saturated with water. The water table separates the groundwater zone that lies below it from the capillary fringe, or zone of aeration, that lies above it. The water table fluctuates both with the seasons and from year to year because it is affected by climatic variations and by the amount of precipitation used by vegetation. It also is affected by withdrawing excessive amounts of water from wells or by recharging them artificially

For the biodiversity of the world, human activity poses a serious threat. This is due to the exponential nature of human population expansion, which ensures that it continues to increase at the same rate regardless of population size.

As it gets bigger, this causes the population to grow increasingly quickly.The populations may increase exponentially for a while, but eventually they hit a carrying capacity when the amount of resources available to them becomes a constraint.

But while they create new technology to sustain the continuously expanding population, humans have continued to operate within carrying capacity.

Land-use change: As people develop cities and dig for resources, they risk destroying the natural landscapes that surround them. As a result, fewer habitats and food supplies are available, which is harmful since it drives out existing species.

Runoff and chemical waste disposal are two sources of pollution.

Answer:

there will be less protein synthesis

Explanation:

When a mutation occurs in a protein coding region it may have several effects. Nucleotide substitutions may lead to no change in the protein sequence (known as silent mutations), change the amino acid sequence (known as missense mutations), or create a stop codon (known as a nonsense mutation).

A silent mutation is unnoticeable, whereas a nonsense mutation will produce a protein which is much different than the original. This is because a nonsense mutation introduces a codon which is completely different than the one before, possibly stopping the protein synthesis short.

A change in a single amino acid that results from a point mutation in the DNA sequence. Nonsense codons (nonsense mutations): The conversion of a codon from one that encodes an amino acid to one that acts as a stop codon due to a point mutation in the DNA sequence.
