Answer:
The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins. A phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group.
Explanation:
Answer:
20 million years
Explanation:
If we have a neutral mutation rate of one mutation per 5 million years, then the total of eight mutation between the two different species would be 20 million years. This is because both species will have 4 mutations in those 20 million years, so combined, both by 4, will have 8 mutations between them. So few mutations on so much time will result in two species that are very similar to each other even after 20 million years of evolution, even making them hardly distinguishable, especially if it comes to defining fossil records from them both. A nice example of this are the members of the felidae (cat) family, which are all very closely related, and are almost identical, thus making it extremely hard to distinguish two species of the same or similar size by their fossils.
Answer:
1/6
Explanation:
Assuming the disorder is not sex linked, Charles is a carrier so he will be Ff.
His wife Elaine can be a carrier or not because her parents must have been both Ff
Possible F1 generation for her was FF, Ff, Ff and ff. She does not have the disease.
Therefore the total chance of her having FF was 1/3 whereas Ff will be 2/3
Probability of the kid having the disease will be calculated by;
(2/3×1/4) +(1/3×0)= 1/6
Answer:
The geosphere contains the elements that make up the Earth's surface.
