Explanation:
In muscle cells, fermentation produces not alcohol but.
Answer:
lactic acid or ATP
Explanation:
In muscle cells, fermentation produces not alcohol but lactic acid and ATP.
What is ATP?Adenosine triphosphate has been an organic compound which gives energy to the living organisms to drive many operations in the living cells. Such as the muscle contraction, muscle pumps, nerve impulse propagation, condensate dissolution, and chemical synthesis.
During the aerobic cellular respiration, glucose reacts with oxygen, forming ATP ( Adenosine triphosphate) that has been used by the cell. Carbon dioxide and water are created as the byproducts. The overall equation for the aerobic cellular respiration is in the cellular respiration, glucose and oxygen react to form ATP ( Adenosine triphosphate).
A monomer has a type of molecule that can make chemical bond with any molecule and can form a long chain and polymer has a sequence of chain of an unspecified or unknown number of monomers.
Therefore, In muscle cells, fermentation produces not alcohol but lactic acid and ATP.

Daniel’s mother takes his baby sister Robin to the doctor for a regular check-up. The doctor tells her that the baby will start to get her first vaccinations on the next visit. His baby sister is a formula-fed baby. Why will the vaccinations provide immune protection for Robin?
Vaccines will provide immune protection for Robin because immunization is one of the main ways to prevent disease. Through it, the body is protected from viruses and bacteria that seriously affect the human being, which can lead to death.
Why vaccinate?After application of doses, the vaccine interacts directly with the patient's immune system, thus producing a response similar to that generated by natural infection. However, it does not cause illness or risk the life of the immunized patient due to possible complications of a naturally caused disease.
With this information, we can conclude that vaccines will provide immune protection for Robin because immunization is one of the main ways to prevent the disease. Through it, the body is protected from viruses and bacteria that seriously affect the human being, and can lead to death.

Which statement is MOST likely the explanation of why certain animals are able to adapt to changing environments?
Answer: D . some species react by mutating
Explanation:
"traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species. This enables better survival and reproduction compared with other members of the species, leading to evolution."-Adaptation | National Geographic Society
Certain animals are able to adapt to changing environments because some species have greater variation in their genetic makeup. Therefore, option A is correct.
What is adaptation?Adaptation refers to the process by which organisms change over time to better suit their environment and increase their chances of survival and reproduction. Adaptations can take many forms, including changes in behavior, physical characteristics, or internal processes.
Adaptation is an important concept in evolutionary biology, as it is a key mechanism by which organisms become better adapted to their environment over time.

What kind of relationship does mistletoe
have with the oak tree? Explain your answer.
Answer:
Parasitic symbiosis is when one organism exploits the other. For example, the mistletoe that grows on oak trees at the Table Rocks is a parasite; it sinks its roots into the oak and steals water and nutrients. The oak suffers from the association; a heavy mistletoe infestation can even kill the tree.

How can populations grow over time?
The amount of organisms born must be more than the number who have died. Available resources in the habitat exceed the number of organisms in the population
The death rate exceeds the birth rate for the population
Both A and B
Both B and C
Answer:
Both A and B.
Explanation:
(1). The amount of organisms born must be more than the number who have died.
This should always be the case with any animal population. If the death rate is higher than the amount of organisms born, the population would eventually become extinct if nothing is done.
(2). Available resources in the habitat exceed the number of organisms in the population.
If the amount of resources in the habitat are less than the entire population itself, the population would eventually use up all those resources and would become extinct.
(3). The death rate exceeds the birth rate for the population.
If the death rate exceeded the birth rate, the population would die off overtime.

It gives us air to breathe, protects us from the Sun's damaging ultraviolet (UV) radiation, traps heat to warm the globe, and lessens the dramatic temperature changes between day and night, all of which contribute to making life possible.
In addition to providing us with the oxygen we need to survive, it shields us from dangerous UV solar radiation. Without it, the pressure needed for liquid water to exist on the surface of our planet would not be possible.
