Which statement about plasma membranes is correct? (1 point)
O Animal cells have cell membranes instead of plasma membranes,
O Both plant cells and animal cells have flexible plasma membranes.
O Plant cells have cell walls instead of plasma membranes.
O Plant cells have rigid plasma membranes.
The statement that is true about plasma membrane is that Animal cells have cell membranes instead of plasma membranes.
What is plasma membrane?The plasma membrane is the membrane found in all cells separate inside of the cell from outside environment. In bacterial and plant cells, a cell wall is attached to the plasma membrane from the outside surface .The plasma membrane consists of a lipid bilayer that is semipermeable. The plasma membrane help to transport of materials inside and outside the cell.
Therefore, plasma membrane is the membrane in cells that separate the outside from the inside of the cell.

Explain how considerations for human health help drive environmental policy decisions.
Answer:
Humans impact the environment, which can, in turn, have an effect on human health. Pollution is caused by human activity, and it also affects human health. Air pollution can cause respiratory problems and water pollution can lead to digestive problems. As human health is affected by these issues, concern increases and policies are enacted that address the causes of the issues. These policies do benefit the environment, but are, in part, brought about by concerns over human health.

What evidence partly supports the idea that the carbon in the cellulose of the tree is the same
carbon that was in the atmosphere before?
O The carbon combined with oxygen to make CO2.
O A chemical reaction occurred that converted sugar from within the tree into starch.
O The oxygen in the cellulose is the same oxygen that was in the air.
O A chemical reaction occurred in which the carbon in the atmosphere became part of a sugar molecule.
If the oxygen in the cellulose molecule found in a tree is the same oxygen that was found in the air, it can be used as evidence to support that the carbon in the cellulose is the same as the one in the atmosphere.
Carbon fixationCarbon, in the form of carbon dioxide, in the atmosphere is fixed into plant tissues as carbohydrates during the process of photosynthesis.
Oxygen is released during the process but the oxygen comes from the splitting of water.
Thus, if the oxygen found in the cellulose of a plant corresponds to the oxygen found in the atmosphere, it is an indication that the carbon in the cellulose is also the same carbon in the atmosphere.

Which is required for both anaerobic respiration and aerobic respiration?
oxygen
O water
O mitochondria
O glucose
Answer: Glucose
Explanation: Substrate is always required. Glucose is the substrate. Anaerobic respiration in absence of o2 and aerobic in presence of o2.
Aerobic respiration totally converts glucose into carbon dioxide and water, whereas anaerobic respiration only fully converts glucose into lactic acid or alcohol (alcohol fermentation) (lactic acid fermentation). Thus, option D is correct.
What similarity in anaerobic and aerobic respiration?The fact that glucose is used as the first molecule in both aerobic and anaerobic respiration is one of their similarities.
Additionally, both aerobic and anaerobic respiration result in the production of ATP, but aerobic respiration generates far more ATP than anaerobic respiration.
For a modest output of ATP, glucose is partially broken down in the cytosol during anaerobic respiration.
For a higher yield of ATP, aerobic respiration uses oxygen to completely break down glucose in the mitochondria.
Therefore, glucose is required for both anaerobic respiration and aerobic respiration.
