Answer:
Polysaccharides generally perform one of two functions: energy storage or structural support. Starch and glycogen are highly compact polymers that are used for energy storage. Cellulose and chitin are linear polymers that are used for structural support in plants and animals, respectively.
Starch serves as energy storage in plants. Glycogen is an even more highly branched polysaccharide of glucose monomers that serves the function of energy storage in animals. Glycogen is made and stored primarily in the cells of the liver and muscles.

3. Why did you calculate the percent change in mass rather than simply using the change in mass?
When making a cross comparison between different sets of data, computing the percent change is more accurate.
Why is accuracy greater with percentage change?It is more crucial to use the percentage change method because, as you can see, it provides a more accurate description of how the data has changed over time. This is because you will typically be working with larger datasets and quantities. The mass change as a percentage reveals how much of a substance's mass has changed over time. For instance, if a rock loses one-fourth of its mass over the course of a year, its mass has changed by 25%.
What does mass change mean?A change that affects the eligibility requirements for the entire caseload or a sizable and discernible portion of the caseload is referred to as a "mass change" and was started by the state or the federal government.

About 2.4 billion years ago, the Great Oxidation Event occurred. During this time, the amount of oxygen in the atmosphere was estimated to go from trace concentrations to concentrations slightly higher than today.
Explain what happened to photosynthetic organisms during the Great Oxidation Event.
Provide examples of what may have occurred to the geosphere and hydrosphere during the Great Oxidation Event.
The answers include the following:
The photosynthetic organisms during the Great oxidation event were killed which led to their extinction.There was more accumulation of oxygen and the existence of more multicellular life forms.What is Great Oxidation?This is referred to as the period in which the earth's atmosphere and the shallow ocean experienced a rise in oxygen content and led to various results.
An example is the extinction of photosynthetic organisms such as anaerobic bacteria and there was also a accumulation of the oxygen content which were present in the atmosphere and water bodies.
The oxygen displaced some gases such as methane which therefore made it more abundant and the main gas which is present in the atmosphere thereby making it the correct choice.

True or False. The relationship between the protists that cause human malaria and humans is an example of commensalism.
The answer to the statement " The relationship between the protists that cause human malaria and humans is an example of commensalism " is false
Understanding the relationship between the malarian parasites and humans.The simple reason why commensalism does not exist between malarian parasites and humans is because, commensalism is not a biological association where an organism cause diseases or has any detrimental effect on the other other. Rather, in commensalism, on of the organisms benefit from the other, and the other commensal does not benefits or harm the other.
However, the relationship which exist between malarian parasites and humans is parasitism. This is because the protist, feed on nutrients from the the body of the host, humans and cause disease known as malaria.
So therefore, the Plasmodium species are the protists which causes malaria to humans and this association is known as parasitism.

Due to the fact that reproductive isolation is essential to speciation, it frequently leads to the formation of two distinct species from a single ancestor under various environmental circumstances.
Reproductive isolationOne of a species' distinguishing characteristics is reproductive seclusion. According to one definition of reproductive isolation, barriers between various species prevent them from mating and having healthy offspring. Reproductive isolation can happen as a result of physiological processes, behavioral, and evolutionary reasons. It takes place during speciation. The process of speciation is how populations develop into separate species. When populations are divided by obstacles or distance, this can happen. The Galapagos bird is one illustration of this.

Phagocytosis occurs in multicellular organisms such as humans whose macrophages of the immune system are able to phagocyte pathogens in immune responses.

Compare the food chain and the food web below. Explain how biodiversity makes one of these more stable than the other. Be sure to use examples from the diagrams. Hint: How does biodiversity in an ecosystem increase organisms' chances of survival?
The food web shows all the feeding relationships while the food chain shows shorter feeding relationships. The wider the food web, the more the survival chances of an organism.
What is the food chain?The food web shows all the feeding relationships that exists in the ecosystem. Recall that the ecosystem is a self sustaining unit in which there is an exchange of materials and energy. Thus, in the ecosystem, all the organisms have what it takes to survive in the system.
The food chain is a shorter feeding relationship between organisms. It ideally involves only three or four living organisms. The food web shows the variety of choices that an organism have when it comes to feeding. As such, the food web is affected by biodiversity. If there are more organisms in the ecosystem, then the food web is wider.

Following a heart attack, lactic acid would accumulate in the tissues due to glycolysis and fermentation, and the production of ATP would decrease. Thus, alternative A and C.
Coronary arteries are blood vessels found on the heart that supply blood rich in oxygen and nutrients to the muscles of the heart. The heart makes use of oxygen, just like any other muscle in the body to break down glucose for energy.
However, if the coronary arteries become narrowed or blocked, the supply of oxygen and other nutrients to the heart is reduced or interrupted. This could happen due to a build-up of cholesterol or plaque in the coronary artery, making it narrow or blocked and leading to a heart attack.
Due to the lack of oxygen, the cells in the heart start to break down glucose using lactic acid fermentation, a type of anaerobic respiration. Since the body cannot further break down lactic acid, it accumulates in the tissues. ATP production also decreases because lactic acid fermentation does not produce as much ATP as aerobic respiration.

Energy is transported from lower to higher trophic levels through the food chain or web. However generally only about 10% of the energy in one level is available for the next level.
Used in metabolic processes or released into the environment as heat. This loss of energy explains why there are rarely more than four trophic levels in a food chain or web. With the 10% rule, each trophy level can only give 10% of its energy to the next level. The remaining 90% is used for survival growth, and reproduction and is lost to the environment as heat.
All energy pyramids begin with the transmission of energy from the sun to the first nutrient-level producers. The first, lowest level contains green plants, which are producers.
