Genetic drift is the dramatic almost sped up process of natural selection due to the untouched habitat the species I lives in. Genetic drift is characterized by the changing in alleles, whether more or less, natural selection could care less as long as they're creating diverse populations.

Why are chloroplasts more on one side of a cell than the other
vaieri [72.5K]

You would be referring to the <em>plant </em>cell.

Answer:

Chloroplasts may be seen on all six sides of a plant cell, which is a three-dimensional entity with typically moderately rounded corners (not in the centre because a big central vacuole fills a very large part of the volume). Chloroplasts are constantly being rearranged by the cell since they are not set in place. Chloroplasts are typically located close to so-called periclinal cell walls, which are oriented in the same 2D orientation as the leaf surface under low light. Chloroplasts seem to "escape" to the anticlinal walls in bright light. Better light harvesting in low light by exposing every chloroplast to light and photoprotection by mutual shading in strong light are likely the fitness benefits provided by this behavior. In the dark, chloroplasts also gravitate toward the anticlinal walls. Thin leaves of submerged aquatic plants like Elodea can be used as microscope specimens to observe chloroplast motions. One can gauge how much light gets through a leaf in land plants. What I just said concerning the top layer(s) of leaves' "palisade parenchyma cells" is accurate. Most of the chloroplasts are found in these cells. Numerous cells in the spongy parenchyma under the palisade layer lack well marked peri and anticlinal walls.

<h2>How did plant cells incorporate chloroplasts in their DNA?</h2>

Chloroplasts must reproduce in a manner akin to that of some bacterial species, in which the chloroplast DNA is duplicated first, followed by binary fission of the organelle (a kind of protein band that constricts so that two daughter organelles bud off). As a result of some chloroplast DNA actually being integrated into the plant genome (a process known as endosymbiotic gene transfer), it is now controlled in the nucleus of the plant cell itself.

You enroll your preschool-age daughter in ballet class. At first, all of the children in the class are clumsy, and their movemen
Ainat [17]

The physiological basis for having your daughter continue is through the way she moves in which up until now, she hasn’t been moving smoothly like other child but rather than awkward. Through this, the mother would likely think that she should let her daughter drop out from that class because she doesn’t seem to have any improvement and if she were to have an improvement with her movements, then the mother would likely let her daughter to continue.

What causes hyponatremia?
baherus [9]

<u>Excessive drinking of water</u> causes hyponatremia.

Hyponatremia is an elementary medical condition that is caused by drinking excessive water. If the concentration of sodium falls below 136 mEq/L, this results in hyponatremia.

Drinking too much water dilutes the sodium in the human body and this results in a high level of water in the body. When the water level rises, cells become enlarged and swollen.

The swelling cells can have harmful impacts on your health by exerting pressure and damaging cell membranes.

Other common causes include diarrhea, liver disease, renal disease, and heart failure. This condition can be cured by taking an IV sodium fluid to raise the degree of sodium.

What are the pores in a leaf called and what is their purpose
Katyanochek1 [597]

Answer: Helps the plant breathe: The epidermis of the leaf contains guard cells that control and regulate the small pores on the undersurface of the leaves. These pores are called stomata. Stomata are responsible for regulating water in and out of the cell. It is also responsible for the exchange of gases across the epidermis.
