What occurs when molecules move into a cell by fusing with the membrane

1 answer:

3 0

Facilitated Diffusion is a process for molecules that cannot be readily diffused through cell membranes. Such molecules may be too large to pass through the pores in the membrane. The movement of these kinds of molecules across the cell membrane is assisted by proteins known as Carrier proteins.

To model ocean water in different places on Earth, a student pours equal amounts of water in two containers. He adds the same am

Nitella [24]

Answer:

The correct answer would be - container 2 will have less salinity than container 1.

Explanation:

The given experiment can give an idea about how the temperature of surroundings can affect the salinity, volume, and density of the water that has the same amount of water and salt dissolved in it. The independent variable or the only variable that is different is their place that has a difference in the temperature. Container 1 is placed in a cool place while container 2 is placed in sunlight.

We know that the warmer the water it takes more space so, therefore, less density. Density and salinity both have a positive relationship so an increase in density increases the salinity and vice versa. Thus, here the salinity of container 2 would be low in comparison to container 1

VMariaS [17]

Examples of allele types are HH. That is option 2.

<h3>Gene Allele </h3>

An allele in genetic studies is an alternative gene form that is located at a particular point of the chromosome. It is usually represented with capital and small letter of the same alphabet.

There are two types of a allele which include:

Dominant allele: This is when the variation seen in a gene produces a noticeable phenotype. This is seen in the gene combination of HH.

Recessive allele: This type of allele does not produce any visible noticeable phenotype. This is seen in hh.

Therefore, examples of allele types are HH
