Answer:

Step 1. A carboxyl group is removed from pyruvate, releasing a molecule of carbon dioxide into the surrounding medium. (Note: carbon dioxide is one carbon attached to two oxygen atoms and is one of the major end products of cellular respiration. ) The result of this step is a two-carbon hydroxyethyl group bound to the enzyme pyruvate dehydrogenase; the lost carbon dioxide is the first of the six carbons from the original glucose molecule to be removed. This step proceeds twice for every molecule of glucose metabolized (remember: there are two pyruvate molecules produced at the end of glycolysis); thus, two of the six carbons will have been removed at the end of both of these steps.

Step 2. The hydroxyethyl group is oxidized to an acetyl group, and the electrons are picked up by NAD+, forming NADH (the reduced form of NAD+). The high- energy electrons from NADH will be used later by the cell to generate ATP for energy.

Step 3. The enzyme-bound acetyl group is transferred to CoA, producing a molecule of acetyl CoA. This molecule of acetyl CoA is then further converted to be used in the next pathway of metabolism, the citric acid cycle.

Answer;

Because it is cheaper to prevent an illness than to treat an illness

Explanation;

-Health Maintenance Organization(HMO) plans offer a wide range of healthcare services through a network of providers who agree to supply services to members.

-According to HMOs it is better to prevent disease rather than to try to find cures for diseases after they occur, therefore they encourage healthy lifestyle practices.

-Prevention typically consists of methods or activities that seek to reduce or deter specific or predictable problems, protect the current state of well-being, or promote desired outcomes or behaviors.

Parents play a vital role in determining the sense of civic duty and apathy, because they are responsible for the upbringing of a individual and teach the kids on how to relate with other people.

A population of mammals leaves an ecosystem because of increased temperatures and decreased rainfall. what’s the reason for this
Serga [27]

The reason for the shift of mammals from the ecosystem due to increased temperatures and decreased rainfall is the change in the abiotic factors of that region.

Ecosystem is defined as how the living species of an area interact within themselves as well as the with the abiotic factors of the region.

Abiotic factors are the non-living things present in an area. These are the soil, mountains, temperature, sun, water, etc. The livelihood of a species in an area is influenced by both the living as well as the non-living factors. For example, if an organism can survive only in high rainfall then low amount of rainfall will be unfavorable condition for it to survive and grow efficiently.

Answer: Relevance

The scope of abiotic and biotic factors spans across the entire biosphere, or global sum

of all ecosystems. Such factors can have relevance for an individual within a species,

its community or an entire population. For instance, disease is a biotic factor affecting

the survival of an individual and its community. Temperature is an abiotic factor with the

same relevance.

Some factors have greater relevance for an entire ecosystem. Abiotic and biotic factors

combine to create a system or, more precisely, an ecosystem, meaning a community of

living and nonliving things considered as a unit. In this case, abiotic factors span as far

as the pH of the soil and water, types of nutrients available and even the length of the

day. Biotic factors such as the presence of autotrophs or self-nourishing organisms

such as plants, and the diversity of consumers also affect an entire ecosystem.

Influencing Factors

Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting

factors restrict the growth of populations. They help determine the types and numbers

of organisms able to exist within an environment.

Biotic factors are living things that directly or indirectly affect organisms within an

environment. This includes the organisms themselves, other organisms, interactions

between living organisms and even their waste. Other biotic factors include parasitism,

disease, and predation (the act of one anim
