What stage of cell respiration is being shown above?

Answers

The stage of cell respiration that is being shown above is oxidative phosphorylation. During this stage, the transport of electrons is coupled to the generation of an electrochemical gradient.

Cellular respiration can be defined as a series of metabolic reactions by which aerobic cells generate energy in the form of ATP.

Cellular respiration has three main stages: glycolysis, the Krebs cycle and oxidative phosphorylation.

During oxidative phosphorylation, the transport of electrons across the mitochondrial membrane is coupled to the generation of an electrochemical gradient, which is then used to generate ATP by an ATP synthase as shown in the figure.

Which renewable resource is not safe for the environment and why?

Answers

Answer: Biomass

Biomass produces gas or many sorts of waste products which are mostly used in burning and cooking. It is plant or animal material used as fuel to produce electricity or heat. Examples are wood, energy crops, and waste from forests, yards, or farms.

But the reason why it can be harmful is because biomass can produce gases like methane. Methane is a  greenhouse gas which can harm the environment and reduce the ozone layer that stops harmful UV light from reaching the earth atmosphere.

An area that has been sampled to have a large population of organisms. Does this represent high biodiversity? Why or why not?

Answers

An area that has been sampled to have a large population of organisms is

regarded as having a high biodiversity.

Biodiversity is defined as the condition in which areas have a high amount

of plant and animal species present there. Any place with a large population

of organisms is said to have a high biodiversity while places with low

population of organisms have low biodiversity.

The stated facts therefore makes an area that has been sampled to have a

large population of organisms represents high biodiversity.

What does it mean for a bacteria or protist to be photosynthetic?
O They are responsible for disease growth.
o They are only responsible for the decomposition of compost.
They are a primary producer of biomass in the ocean.
They are multi-cellular organisms.

Answers

C is the right answer

If a bacteria or protist is photosynthetic that means they are the primary producer of biomass in the ocean.

What are primary producers?

Primary producers are organisms that produce their own food through the process of photosynthesis or chemosynthesis. These organisms are the base of the food chain in most ecosystems, as they provide the energy that drives the ecosystem.

Photosynthetic primary producers, such as plants, algae, and some bacteria, use energy from sunlight to convert carbon dioxide and water into glucose, a type of sugar. They release oxygen as a byproduct of this process.

Chemosynthetic primary producers, such as some types of bacteria, use energy from chemical reactions to convert inorganic substances into organic matter. These reactions typically involve the oxidation of sulfur compounds or methane, and they occur in environments where sunlight is not available, such as deep ocean vents and underground coal mines.

Primary producers are important because they provide the energy that drives the food chain and support the rest of the ecosystem. Without primary producers, higher-level consumers, such as herbivores and carnivores, would not have a source of energy.

Why is it that dominant diseases are not as common as recessive ones?

Answers

Answer:

Mainly because if a disorder is dominant, then it will be manifested by all who have the gene. If the disorder is severe, then it will reduce the chances of the individual surviving to grow up and reproduce (unless the disorder only manifests symptoms in later life). If they do reproduce, then 50% of their offspring will inherit the gene, and be at a similar disadvantage in reproduction. Thus, there is likely to be selection against the gene. By contrast, a recessive disorder is only manifested if both parents pass on the abnormal gene, and an individual with one gene for the disorder is usually at no disadvantage. Thus, there is much less selection against abnormal recessive disorders.
