A body of granite was found to underlie sandstone. pieces of sandstone were found in the granite. which is younger, the granite

serg [7]

It is obvious that the sandstone is older than the granite. This is because the sandstone had to already exist when the granite formed from molten rock, as some of the sandstone was captured within the layer of hardening granite. The geological principle of inclusions supports this conclusion.<span> Inclusions, in this case the sandstone, are always older than the rock they are found in. </span>

What are the benefits and drawbacks to using solar, geothermal, and wind power as alternative sources of energy

Damm [24]

The benefits are that you don't have to rely on limited resources and you won't be contribution to global warming but the drawbacks are that you have to find a way to make it run by itself and deal with it not working sometimes.

6. A scientist measures the circumference of acorns in a population of oak trees

melisa1 [442]

Answer:

6. 2 cm

8. Greater than 2 cm and less than 2 cm

Explanation:

Complete Question

6. A scientist measures the circumference of acorns in a population of oak trees and discovers that the most common circumference is 2 cm. What would you expect the most common circumference(s) to be after 10 generations of stabilizing selection?

-2 cm

-Greater than 2 cm or less than 2 cm

-Greater than 2 cm and less than 2 cm

-Can't tell from the information given

8. Refer to question 6, but this time answer what you would expect after 10

generations of directional selection.

-2 cm

-Greater than 2 cm or less than 2 cm

-Greater than 2 cm and less than 2 cm

-Can't tell from the information given

Solution -

6. In an stabilizing selection, the average trait of a given population is favored over extreme values. Hence, it can be said that one specific trait is over presented in a given population. For example – uniform human birth weight, number of eggs a bird lay etc.

Here in this case if most common circumference is 2 cm , then the tree population will try to have this trait as a stabilizing trait.

Thus, option A is correct

8. In a directional selection, the genetic variation decreases as per the environmental change. And hence the average trait will not be selected. Instead traits either higher or lower the average values will be preferred.

Thus, option C is correct

1. You are studying an integral membrane protein of the plasma membrane. It has a single transmembrane domain and the N-terminal

Drupady [299]

Answer:

A 22 to 25 amino acid sequence present in the central section of the protein, which gives rise to an alpha helix in the membrane is known as the stop-transfer anchor sequence. The sequence plays an essential function in targeting the protein towards the plasma membrane. On the other hand, it also ceases targeting of the protein towards the endoplasmic reticulum, which was started by the signal peptide.

Thus, the process of translation of the remaining of the protein occurs within the cytosol due to the tethering of the transmembrane domain. In the stop-transfer anchor sequence, the hydrophobic amino acids present are isoleucine and valine. After mutation, these amino acids get converted into arginine and lysine, thus, hydrophilic amino acids replace hydrophobic amino acids in the sequence.

Due to this, the transmembrane domain cannot be targeted towards an integral part of the plasma membrane by the short transfer anchor sequence, and therefore, now the translocation of the protein will take place towards the endoplasmic reticulum as initiated by the signal peptide at the beginning.
