Answer:
if we cross BB with bb none of the offspring will have blue eyes so the answer is <em><u>b 0%</u></em>
Explanation:
Answer:
so its telling you to compare and contrast the diagrams like what changed and to describe the data you want to examine so whats going on is it changing or staying the same?
Explanation:
Fibroblasts, cells found in the connective tissues of the body, make up the hypodermis. These produce collagen proteins, which aid in preserving the body's structural foundation.
- The body's bottom layer of skin is called the hypodermis. It serves a variety of crucial roles, including energy storage, tying the muscles and bones beneath the skin's dermis layer to one another, keeping the body warm in a variety of temperatures, and guarding against injury-related harm.
- The hypodermis shrinks with ageing, the skin begins to sag, and the skin is more susceptible to damage and injury.

1) Data:
dominant allele- A
recessive allele- a
Heterozygotic: Aa (only carries the allele)
Homozygotic recessive: aa (expresses the disease)
Homozygotic dominant: AA (doesn't carry or expresses the disease)
2)The first cross between Jim and his first wife originated a offspring with
<span>cystic fibrosis</span>. That offspring has the genotype aa and for that to happen both parents need to be a least carriers or express the disease. The exercise rules out the second case, which makes Jim a carrier.
3)Now between Jim and Martha:
From the previous step, we already found that jim is a carrier and the exercise also tells us that Martha is one too. So, their genotype is: Aa.
The cross: Aa x Aa
The probability:
1/4 aa = 25%
2/4 =Aa
1/4 - AA
the probability of having a <span>baby with cystic fibrosis is 25%</span>
The autonomic nervous system helps in regulating some processes which are without a person’s conscious effort. Some of these processes are breathing rate, blood pressure. The autonomic nervous system is divided into two parts- sympathetic and parasympathetic. In general, the sympathetic part prepares the body for an emergency situations such as sight or flight, whereas, the parasympathetic controls body process during normal situations.
Sympathetic part is at work in these situations:
- Ross feels nervous because he misplaced his important work documents.
- Dory sees a bear while hiking in the woods, and her heart rate increases.
- Rodrigo’s breathing increases when he hears a scary sound.
Parasympathetic part is at work in these situations:
- Maya feels her heart rate slow down after strenuous exercising.
- Sofia’s muscles relax when she finds her missing cell phone.
- Lisa feels calm after yoga class.
