Answer:
The Law of Dominance states that the dominant allele completely masks the presence of a recessive allele. The law of segregation states that the two alleles for each trait separate during the formation of gametes and that during the formation of new zygotes, the alleles will combine at random with other alleles. A parent gives only one allele to make a gene. The law of independent assortment says that the allele that a gene receives first has no bearing on the allele it will receive second.

A species of rodent lives in a moist forest
climate. Over time, the elimate becomes drier
and more desertlike, Which adaptation would
most likely improve the chances that the rodent
species
could survive as its environment
changes?
A. having dark hair and small ears
B. living above ground in damp areas
C. being able to eat only one type
of berry
D. being able to eat plants that survive in the
changed environment
The possibility that a rodent species may have survived because of a change in its environment that is capable of eating plants that survive the changed environment. So, the correct option is (D).
What is Adaptation?Adaptation is defined as the process by which a species adapts to its environment as a result of natural selection acting on variation over many generations.
Organisms are adapted to their environment in their structure, physiology, and genetics, in their locomotion or dispersal, in their means of defense and attack, in their reproduction and development, and in other respects.
It is described as the ability of an organism to adapt to its environment and change through time, referring to the term "adaptation theory", known as the "survival of the fittest" idea. In this instance, rodents become able to eat plants that survive the changed environment.
Thus, the possibility that a rodent species may have survived because of a change in its environment that is capable of eating plants that survive the changed environment. So, the correct option is (D).

In a car accident, Jane suffered a chest injury that resulted in impaired breathing and respiratory acidosis. How will her body compensate for this imbalance?
Her body will compensate for this imbalance, trying to get more oxygen from the environment, making her breathe harder for a balance between carbon dioxide and oxygen in the bloodstream.
What is respiratory acidosis?When breathing is deficient, which can lead to hypoventilation, the transfer of CO2 to the outside is reduced and its concentration increases in the blood, decreasing blood pH. if a picture of acidosis.
With this information, we can conclude that her body will compensate for this imbalance, trying to get more oxygen from the environment, making her breathe harder for a balance between carbon dioxide and oxygen in the bloodstream.

While washing her hair, Olivia noticed that she was losing a lot of hair. She visited a clinic, and the physician reassured her that her hair would grow back. How do you think Olivia’s hair will grow back?
Answer:
The right option is; The hair will grow back by undergoing meiosis. Meiosis is a type of cell division in which the number of parental chromosome is reduced by half, and there is formation of four haploid daughter cells that are genetically distinct from the parent cell that produced them. Meiosis only occurs when the cell needs to reproduce and it occurs in all eukaryotic, se,xually-reproducing animals and plants.

what happens if u lose brain cells
Answer:
If you actually began losing brain cells then you could begin to have difficulties with motor and other skills. It may affect your nervous system, or pretty much anything else in your body depending on which ones you lose, meaning that your body may stop functioning properly. You may lose your ability to remember things or perform everyday tasks. It is true that some neurons die as people age because of the waste they accumulate that causes them to lose their function and degenerate. This can affect some elderly people by appearing as conditions like Alzheimer's, Dementia, or Parkinson's. While this is a natural event, some injuries or damage to the brain due to accidents, or the use of substances, cause destruction or deterioration in younger, healthier brains.

What do vaccines contain?
A: Dead or weakened versions of pathogens
B: Live pathogens
C: Antibiotics
C
D:
Antibodies
Answer:
A
Explanation:
The whole purpose of a vaccine is to expose your body to what the disease would feel like if you actually had it so your body builds up an immunity to the bacteria, virus, etc. Obviously they won't put the disease at its full form in the vaccine because you'll get sick and not build an immunity, so they must put in a weakened version of the disease in the vaccine. That's your answer.

A student grew flowering plants next to one another in the school greenhouse. Some of the plants had yellow flowers, while some had white flowers. When these plants produced seeds, the student planted them. All the new plants that sprouted from the seeds had yellow flowers.
Which of the following best explains why the new plants only had yellow flowers?
A. None of the seeds from the white plants sprouted.
B. The new plants inherited dominant genes for yellow flower color.
C. The soil the plants were in caused the flowers to turn yellow.
D. The new plants received more sunlight than the parent plants.
Answer:
B. is the answer.
Yellow(Yy) is a dominant allele, and although white(ww) is inherited from the parent gene, Yy, white is a recessive gene. That means it is most unlikely to be visible through phenotype(term for visible characteristics).
