Answer:
25%
Explanation:
From the description;
The parents: half shaded circle and square = heterozygous parents
The offspring:
unshaded square = homozygous normal
half shaded circle = heterozygous normal
half shaded circle = heterozygous normal
completely shaded square = affected (homozygous abnormal)
The unshaded and half shaded offspring are normal and do not have sickle cell anemia. The completely shaded square represents a male offspring with sickle cell anemia.
<em>Out of 4 offspring, 1 is affected for sickle cell anemia. Hence the percentage of the offspring that have sickle cell anemia is 25%.</em>
Answer: Many of the bacteria in the body play an important role in human survival. Bacteria in the digestive system break down nutrients, such as complex sugars, into forms the body can use. Bacteria in the digestive system break down nutrients, such as complex sugars, into forms the body can use. Non-hazardous bacteria also help prevent diseases by occupying places that the pathogenic, or disease-causing, bacteria want to attach to. Some bacteria protect us from disease by attacking the pathogens.
Explanation:
Answer:
to make more diploid cells.
Explanation:
It works by copying each chromosome, and then separating the copies to different sides of the cell. That way, when the cell divides down the middle, each new cell gets its own copy of each chromosome.
Since a lot of people like to litter and not clean up around their community, it would attract rodents (mice, rats, raccoons). Also, bugs and insects (like cockroaches) would be attracted to the trash in the area. If there are rats then, something must eat them. This means that cats would be apart of this community. Humans naturally like to settle where water is so, fish would also be something to consider as your answer.
