Continue to consume the calcium recommended for non-pregnant women because calcium absorption increases during pregnancy which will provide for the fetus.

What is the relationship between undisturbed sedimentary rock layers and fossils?
Juli2301 [7.4K]

Answer:

Older fossils are found in deeper layers of sedimentary rock.

Explanation:

The relationship between undisturbed sedimentary rock layers and fossils is that older fossils are found in deeper layers of sedimentary rocks.

This is one of the premise of the law of superposition and principle of fossil and fauna succession.

  • An undisturbed sequence is one in which the sedimentary layers have been arranged sequentially.
  • The oldest is at the bottom and the youngest on top.
  • Also, fossils grade in this manner too.
  • The oldest fossils will be in the oldest bed which is the deepest layer.
  • The youngest bed will contain the youngest fossils in like manner too.

In a hardy-weinberg population with two alleles, a and a, that are in equilibrium, the frequency of allele a is 0.2. what is the
Allushta [10]
The Hardy-Weinberg equation is as follows:
( {p + q})^{2}  = 1
{p}^{2}  +2pq +   {q}^{2}  = 1
Where:
(convert all % to decimals)

p= homozygous dominant
q= homozygous recessive
pq= heterozygous

While you did not specify whether the 0.2 frequency was for dominant or recessive, we can still figure out the answer.

Using the 1st equation, we can solve for the other dominant/recessive frequency:

1-0.2=0.8

Meaning that:

p= 0.8 & q=0.2

If the heterozygouz frequency is 2pq, then it becomes a simple "plug & chug" sort of approach.

2(0.8)(0.2)= 2(0.16)= 0.32

So, the heterozygous frequency would be:
0.32

Hope this helps!
