Which of the following pairs is not correctly matched?
Elden [556K]

Answer:

B

Explanation:

T tubules do not generate ATPs. This is done by mitochondria. T tubules are the invagination of cell membranes into the muscle cells. They allow for rapid actuation of the action  potential by the muscle cells. They do this by synchronizing the release of calcium ions that are important in muscle contraction.

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

Why are lipids and proteins free to move laterally in membranes?
Rashid [163]

Correct option C) Hydrophilic portions of the lipids are in the interior of the membrane.

Lipids and proteins free to move laterally in membranes because both are inserted into a fluid lipid bi-layer and they are able to diffuse laterally through the membrane.

Lipid Composition of Cell Membranes is a important property of lipid bilayers which is behave as two-dimensional fluids where individual molecules are rotate and move freely in lateral directions

Membrane proteins and phospholipids both are unable to move back and forth between the inner and outer leaflets of the membrane at an appreciable rate. Phospholipids in the lipid bilayer can either move rotationally, laterally in one bilayer, or undergo transverse movement between bilayers.

Identify one process that is responsible for the variations in coloration observed in guppies
natima [27]
Here's the excerpt.

Guppies are small, tropical freshwater fish that display wide variation in coloration. Some have bright splotches of blue, red, and orange, while others are quite drab and dull. Research has shown that females prefer to mate with brightly colored males; however, this trait makes them more likely to be seen. Guppies, like all species, must be able to both sur<span>vive and reproduce in order to avoid extinction

One process that is responsible for the variations in coloration observed in guppies is that how females mate with male guppies. They prefer to mate with brightly colored males.</span>
