Asexual Reproduction occurs when there is only one parent that gives rise to an offspring which has the identical genetic makeup of the parent. It occurs in most single celled organisms such as bacteria and some multicellular organisms such as fungi and some plants. Some advantages of asexual reproduction are it is fast and efficient. It does not require a male and a female. Organisms can reproduce quickly! A disadvantage is that there is no genetic diversity and it can only be done by simple organisms.

Sexual Reproduction involves the combining of genetic information from two parents to produce a new organism that is a combination of both parents. It occurs in most complex organisms. Some advantages to sexual reproduction are that it creates genetic diversity. It allows for evolution of the species. A disadvantage is that it requires two organisms to reproduce, a male and a female. It also requires more energy than asexual reproduction.

Using the table below, list at least two advantages and disadvantages of Asexual and Sexual Reproduction.

ATP or Adenosine Triphosphate is the primary source of energy for most cellular processes including muscle contraction. ATP is synthesized through several energy sources during muscle contraction.

The sources of energy that synthesize ATP for muscle contraction are as follows:Glycolysis: This process occurs in the cytoplasm and it converts glucose or glycogen into pyruvate. The energy released in this process is used to synthesize ATP. The net gain from glycolysis is two ATP molecules. Krebs cycle or Citric acid cycle: This cycle occurs in the mitochondria and it generates ATP by oxidizing acetyl-CoA to carbon dioxide. The total yield of ATP from one glucose molecule is 36 or 38 ATP molecules depending on the source of glucose. Electron transport chain: This is the final stage of oxidative metabolism that occurs in the inner membrane of mitochondria. During this process, electrons are transferred from one molecule to another and this generates a proton gradient. This gradient is used by ATP synthase to synthesize ATP from ADP and inorganic phosphate (Pi). The yield of ATP from one glucose molecule in this process is 28 or 32 ATP molecules depending on the source of glucose.

The benthic sediment with the lowest percentage of organic matter would likely be open ocean deep sea sediments.

Open ocean deep sea sediments, as mentioned in option B, generally have the lowest percentage of organic matter compared to the other listed sediment types. This is because open ocean environments are characterized by low primary productivity, meaning there is a limited supply of organic material sinking to the seafloor. In these areas, nutrient availability is typically low, and the rate of organic matter deposition is slow. As a result, the sediments that accumulate over time contain a lower percentage of organic matter.

On the other hand, sediments in temperate deep sea regions (option A), deep sea regions beneath the equator (option C), abyssal sediments beneath gyre centers (option D), and sediments on the shelf-slope break (option E) may have higher percentages of organic matter. These areas often receive higher inputs of organic material due to factors such as increased primary productivity, nutrient availability, or proximity to landmasses where terrestrial runoff contributes organic matter to the marine environment.

D) Antbiotics kill damaging bacteria by rupturing cell walls.

Explanation:

Antibiotics are drugs that kill bacteria or slow their growth. They function in various ways, but one common mechanism is by interfering with the construction of the bacterial cell wall, causing the bacterium to burst and die. Importantly, antibiotics are effective against bacteria, but they do not work against viral infections because viruses do not have cell walls.

The other options are not accurate:

A) Antibiotics do not attack all bacteria cell membranes. They selectively target specific types of bacteria, and some bacteria are naturally resistant or can become resistant to certain antibiotics.

B) Antibiotics are not effective against viruses. Viruses lack the structures that antibiotics target, such as cell walls.

C) Antibiotics do not protect the membranes of bacterial pathogens. Their purpose is to kill or inhibit the growth of these pathogens, not to protect them.

C. The hypothesis was false, and scientists should replace it with a new one.

Explanation:

because

The results of one new experiment did not support an accepted hypothesis as there was a flaw in the experiment’s design or errors when it was conducted. Thus, the correct option is A.

A hypothesis is a prediction which is based on some observations or evidence. A hypotheses must be testable, and once it is tested, it can be supported by evidence such as observation of the experimental study. If a statement is made which cannot be tested and disproved, then it is not a hypothesis.

A hypothesis can be rejected or modified, however it can never be proved correct 100% of the time based on the studies. For example, a scientist can form a hypothesis which states that if a certain type of tomato has a gene for red pigment, then that type of tomato will be red.

Homeostasis control in living things is exerted over all of the following except response to stimuli. The correct answer is C.

Homeostasis is the ability of a living organism or cell to maintain a stable internal environment despite changes in external conditions. It involves the regulation of various physiological parameters, such as temperature, pH, fluid balance, moisture level, acidity level, and glucose levels, through feedback mechanisms that help to maintain a balanced and stable state.

This allows the organism or cell to function optimally and respond effectively to environmental challenges or changes. Homeostasis is essential for survival and is maintained by complex physiological and biochemical processes that work in harmony to keep the internal environment within a narrow range of acceptable levels.

However, the response to stimuli, such as sensory input from the environment, is not directly controlled by homeostatic mechanisms but by other physiological processes such as reflexes, sensory perception, and decision making in the brain.

There is a direct inversely proportional relationship between albedo and greenhouse gas concentration. The more gas concentration, the less albedo.

The term albedo refers to the radiation reflected from the earth's surface to the universe.

Albedo might be defined as a relation between reflected light from a particle and the incident light. It is the incident radiation fraction reflected by any object.

According to this information, we could assume albedo impedes elevated temperatures on the Earth by reflection events.

Naturally, different surfaces have different albedo values, which means global albedo variations. These are natural processes that vary according to exogenic and endogenic variations.

However, these natural events are worsened by the variations caused by human beings' actions, which increase greenhouse gases, decrease albedo, and increase global warming.

The increase in gas concentration and atmospheric dust is additional material that interposes between the Earth's surface and the universe, decreasing the energy reflected in the universe.

The increase of greenhouse gases, such as CO₂, decreases albedo. More elements (gases and dust) in the environment can absorb the incident energy, increasing, decreasing reflection, and increasing global warming.

There is a direct inversely proportional relationship between albedo and greenhouse gas concentration.

More gas concentration ⇒ Less albedo.

Frogs lay eggs that devplop into tadpoles and then into adult frogs. This sequence of changes is an example of how living things A. go through a life cycle

A life cycle refers to the series of stages that an organism passes through from its birth until its eventual death. In the case of frogs, this process begins with the fertilized eggs, which hatch into tadpoles. As tadpoles grow, they undergo a transformation called metamorphosis, where their body structures change significantly, this includes the development of lungs, legs, and the loss of their tails. Once metamorphosis is complete, the tadpoles have become adult frogs, capable of reproducing and starting the life cycle anew.

This life cycle is a crucial aspect of the survival and reproduction of the frog species, ensuring the continuation of their population. Each stage of the life cycle plays a vital role in the growth, development, and overall success of the species in their respective ecosystems. So therefore The sequence of changes in frogs, where they lay eggs that develop into tadpoles and then into adult frogs, is an example of how living things A. go through a life cycle.

The abiotic factor that defines the limits of a riparian zone is the availability of water. Riparian zones are typically located adjacent to water bodies, such as streams, rivers, or lakes, and their boundaries are determined by the presence or absence of water.

Riparian zones are important habitats that provide many ecological benefits, including nutrient cycling, water filtration, and wildlife habitat. The availability of water is a crucial abiotic factor that influences the distribution and abundance of riparian vegetation and wildlife.

Riparian vegetation is adapted to thrive in areas with high water availability, and the presence of water also provides a critical source of moisture for animals that live in these zones. As a result, the boundaries of riparian zones are largely defined by the availability of water and are often characterized by a transition from wet to dry conditions. Understanding the limits of riparian zones and the factors that influence their boundaries is important for effective management and conservation of these important habitats.

Answer:

To be a possible answer to a scientific question, a hypothesis must be testable.

When conducting an experiment, there are different aspects to consider, such as the question that drives to the reseach, the hypothesis, theoretical framework, variables involved -independent, dependent, and controll-, methodology, study groups, data analisys, among others.    

In the exposed example, Pincky is lacking theoretical framework, defining which are the study groups, methodology to collect data, and a description of data analysis.

---------------------

The scientific method is a research method that consists of systematic observations, measures, experimentation, analysis, and verification of a hypothesis. It is based on two aspects: reproducibility, which is the capability of reproducing the experiment in any other place by any researcher, and refutability, which is the susceptibility to be refused.

When conducting an experiment, you need to consider,

• Definition and problem statement. The question for which there is not an answer yet.

• Hypothesis formulation. A hypothesis is a scientific conjecture, not verified, that requires corroboration.

• Data collection and analysis. This step involves testing the observations.

• Results

• Verification of hypothesis. This step involves the deriving of the working hypothesis.

• Discussion and Conclusion.

Previous knowledge about the study object is always required for a better understandig.  A question the investigator wants to answer. The main goal of the study, which is basically what the investigator wants to find out. The researcher makes a hypothesis to predict what is going to happen. The experiment is to be performed to answer the question. The conclusions through which the hypothesis might be rejected or accepted.
