Answer:
glucose → lactic acid.
Explanation:
hope it helps
The statement that will best compare aerobic and anaerobic respiration is :
More ATP is generated during aerobic respiration than during anaerobic respiration.Aerobic respiration is the type of cellular respiration which is a fixed metabolic reaction that occurs in the presence of oxygen while anaerobic respiration ia a type of cellular respiration which occurs in the absence of oxygen. Both respirationary process yields the required energy ( ATP ) in an organism that facilitates the proper functioning of the organism.
Hence we can conclude that The statement that will best compare aerobic and anaerobic respiration is : More ATP is generated during aerobic respiration than during anaerobic respiration.

5. In a tundra ecosystem, the carrying capacity for arctic hares is about 400 individuals. Which of these events is MOST likely to reduce the carrying capacity for arctic hares in the ecosystem by at least 25 percent?
(A) a severe storm that kills about 100 adult and young arctic hares
(B) a 25 percent decrease in the populations of foxes, wolves, or other predators of arctic hares
(C) the arrival in the ecosystem of a species that competes with the arctic hare for its food
(D) a temporary increase in the arctic hare population to more than 425 individuals
(E) a mutation that introduces a new fur color to the arctic hare population
A temporary increase in the arctic hare population to more than 425
individuals.
Hares are among the primary consumers as they are herbivores while foxes
are secondary consumers which feeds on the hares.Foxes will hunt the
hares for food which will drastically reduce their population
Increasing their population by 425 individuals with the hares having a
population of 400 will surely decrease their carrying capacity in the tundra
ecosystem.

the production of alcohol by yeast cells is the result of
Answer:
Fermentation
Explanation:
Hope this helps!
The production of alcohol by yeast cells is the result of anaerobic respiration. The correct option is D).
What are anaerobic respirations?All living cells undergo respiration, a chemical activity that releases energy from glucose. Without oxygen, anaerobic respiration occurs and produces less energy but does it more quickly. Fermentation refers to anaerobic respiration in microorganisms.
When you work out vigorously, your muscles engage in anaerobic respiration. Compared to aerobic respiration, less energy is released because glucose is not completely broken down.
During intense activity, lactic acid accumulates in the muscles. Later, the lactic acid must be oxidized to produce carbon dioxide and water.
Therefore, the correct option is D) Anaerobic respiration.

what is the primary action of antidiuretic hormone?
Answer:
The primary action of the antidiuretic hormone is that it causes collecting ducts in the kidneys to reabsorb more water.
Explanation:
Human vasopressin is also known as the Anti-diuretic hormone (ADH) causes kidney-collecting ducts to reabsorb more water.
What is Anti-diuretic hormone (ADH)?Human vasopressin is also called antidiuretic hormone, arginine vasopressin or argipressin. It is defined as the hormone synthesized from the AVP gene as a peptide prohormone in neurons in the hypothalamus that converts to AVP.
ADH is the hormone that helps constrict blood vessels and helps the kidneys control the amount of water and salt in the body which helps control blood pressure and the amount of urine. This reduces the amount of urine released and the nature of urine becomes hypertonic which is concentrated. Because of this type of action, vasopressin is known as an antidiuretic hormone.
Thus, Human vasopressin is also known as the Anti-diuretic hormone (ADH) causes kidney-collecting ducts to reabsorb more water.

Answer:
B
Explanation:
Pharmacodynamic tolerance involves changes in neurons, while metabolic tolerance involves changes in enzymes.
What is pharmacodynamics?
"Pharmacodynamic interactions" are interactions in which substances directly affect one another's effects. Sedatives, for instance, typically potentiate one another.
Neurons are the cells of the nervous system the cell plants are branch-like structures like the roots of a plant, they contain absorb information using electrical impulses and transport it into different areas of the brain.
The central nervous system contains the brain and the hypothalamus, and the peripheral nervous system contains all the neuron cells.
Therefore, while metabolic tolerance affects changes in enzymes, pharmacodynamic tolerance involves changes in neurons.

Answer:
Yes
Explanation:
Write your question first bro.
Viruses and bacteria can infect human cells. Bacteria are living organisms, while viruses are not. How do you think the treatment for viral and bacterial illnesses differ? How do you think they affect healthy body cells? Explain your response. NO PLAGIARISM WILL BE REPORTED IF SO.
Viral infections cause similar symptoms as bacterial infections. Antibiotics treat bacterial infections but do not treat viral infections. Some antiviral medicines are used to treat viral infections.
The misuse of antibiotics to treat a viral infection contributes to antibiotic resistance.
Antibiotics kill bacteria without damaging the body’s cells. They do so by interfering with how bacteria live and reproduce. Normal body cells work in different ways, so they’re not affected.
While antibiotics are effective in treating bacterial infections, they can also damage the immune system when used incorrectly or too frequently. Therefore, the doctor should prescribe antibiotics only when needed and sparingly.

What is the effect of the biogeochemical cycles?
Answer:
The effect is to promote a cycling of the elements, ensuring that they are used and later available again. This is an extremely important factor, as some elements are essential for living beings, and their constant use, without replacement, could lead to the extinction of species.
Explanation:Biogeochemical cycles are processes that occur in nature to ensure the recycling of chemical elements in the environment. It is these cycles that enable the elements to interact with the environment and living beings, that is, they ensure that the element flows through the:

In which biological event is chemical energy transformed into mechanical energy?
O muscular movement
O
photosynthesis
O bioluminescence
Muscular movement is the correct answer
The event in which the chemical energy transformed into mechanical energy is muscular movement. The correct option is A.
What is muscular movement?Muscles contract and then relax to move body parts. Muscles can pull bones, and yet they can't push them back into position.
As a result, they function in pairs of flexors and extensors. To flex a limb at a joint, the flexor contracts.
We discussed the skeletal system and the gestures that can take place at joints, such as flexion, extension, abduction, inversion, and so on.
These movements are produced by skeletal muscles pulling bones in different directions.
When ATP is hydrolyzed during cross-bridge cycling, chemical energy is converted to mechanical energy during muscle contraction.
As the muscle deforms or performs external work, this mechanical energy is distributed and stored in the tissue.
Thus, the correct option is A.
