What is an effect of genetic drift on a gene pool?
Ahat [919]

Genetic drift happens by chance and can make an allele disappear completely from a gene pool, even if it was a desirable trait that should have been passed down to offspring. The random sampling style of genetic drift shrinks the gene pool and therefore alters the frequency the alleles are found in the population.

Increased force output of the synergists for hip extension to compensate for the weakened gluteus maximus is an example of which
olga_2 [115]

Answer:

b. Synergistic dominance

Explanation:

The stabilizing muscles will always be <u>synergistic</u>, since only from the synergies (hence the term synergist) that arise from joint work is efficient and controlled movement possible. However, not all synergists will be stabilizers. Stabilizer will be one that, thanks to the geometric arrangement of its fibers, will have the ability to maintain alignment in the joint and stable the axis of rotation.

In the case of knee extension, we would have as stabilizers all the antagonists who, because the flexion axis is virtual and not physical, must maintain the stability of said axis. If the axle were physical, such as the wheel in a horse carriage, or on a skateboard through the bearings, the antagonistic muscles would not be necessary for this purpose, because the fixed axis would maintain the position. Since the joints of living beings do not have a fixed physical axis, it is the muscles themselves, specifically the antagonists, who must be responsible for maintaining the stability of the joint creating a virtual axis on which rotation occurs.

Sand that extends from a coast into open water is called a barrier spit. <br> a. True <br> b. False
AysviL [449]
<span>It is True - Sand that extends from a coast into open water is called a barrier spit.

Barrier spits are formed when there is a deposit on the shoreline due to the lateral movement of water.

The waves are known to hit the shoreline at a particular angle which cause the lateral movement of water accompanied with the sedimentation along the coastline in the direction of the wave motion.</span>
