Answer:

Variation existed in the traits of the fox population. Foxes with smaller ears and noses were able to stay warmer and were more likely to survive and reproduce to pass their genes on to offspring. Over time, the fox population showed a shift to smaller ears and noses.

Recent research has demonstrated a correlation between the presence of certain types of Gram-positive bacteria in the human gut

scoundrel [369]

Answer:

The correct option is A.<u><em> Normal microbiota may significantly impact human health and disease.</em></u>

Explanation:

A wide number of microorganisms are present on or inside of our body. All these microorganisms make up the natural microbiota. The normal microbiota is very important to maintain the health of the host.

However, any microbial imbalance can lead to causing disease in its host. The microbiota of the gut have a disease-promoting effect but can also have protective properties. Differences in this microbiota can lead to serious conditions.

harina [27]

The mitosis process of the cell will be inhibited in the saline environment.

Due to the response to water and salt stress that occurs via ABA which increases the expression of ICK1 that interacts with CDKA and inhibits histone H1 kinase activity (a protein involved in chromatin formation during phase S of the interphase).

This phenomenon is applied to highlight in the living cell the existence of chromosomes at the interphase, thus demonstrating the permanence of the chromosomal structure.

Ray Of Light [21]

Explanation:

(3) active transport

The molecules would be moving against their concentration gradient from a region of low concentration to a region of high concentration.

While cells facilitate the transport of molecules via movement across the cell membrane, there many different mechanisms. These include passive diffusion, facilitated diffusion, and passive transport. However some very large molecules require specialized type of active transport, which requires energy in the form of ATP, in order to move substances across the membrane against their concentration gradient.

Active transport is a mediated process that requires an energy input and the use of specialized membrane proteins to move against the concentration gradient. These proteins require energy in the form of adenosine triphosphate or ATP in order to facilitate necessary conformational changes to the large protein molecules to alter the spatial location of the molecule. For instance, with Na+, K+ pumps in cell membranes.
