A membrane's permeability has an impact on the diffusion rate. As membrane permeability increases, the diffusion rate rises.
- The dispersion of materials is also impacted by changes in temperature and pressure values.
- The passive diffusion rate of penetrated molecules through the biomembrane can be used to quantify a membrane's permeability.
- It is well acknowledged that the permeability of any particular molecule depends mostly on its size, polarity, charge number, and molar mass.
- The capacity for materials to flow into and out of a membrane is known as permeability. The ease with which a chemical can diffuse across a cell membrane determines its permeability.
- Only chemicals that can dissolve in fat can typically pass through a cell membrane.
- The electrical potential gradient across the cell membrane and the concentration gradient of the permeant ion across the membrane together make up the net electrochemical driving force.

Answer:
Iodine influences the expression of the genes that control metamorphosis.
Explanation
When conducting a population sampling study, on the first capture attempt, we tag, count, and release the captured individuals. Thus, option "D" is correct.
<h3>What is the mark-recapture method?</h3>
This is a method commonly used in ecology to estimate the animals in the population. A portion of the population is captured, marked and released. Another part of the population will, later on, be captured. This can be used to estimate the population in an assumption that the portion that was captured is proportional to the entire population. This is obtained by dividing the number of marked individuals by the individual marked on the second capture. This is one of the simplest and most practical methods of estimating the population.
Thus, option "D" is correct.

Answer:
Snow line
Explanation:
The lowest elevation at which layer of a permanent snow occurs in the summer is known as the snow line.
Snow line is defined as the boundary between a snow covered area and a snow free one.
The lowest level connotes with the level of snow during the summer because the temperature is warm at this period in time. Below this level, all the glaciers are frozen and will not melt in any way.
During winter, the snow line can rise due to drop in temperature.
Answer:
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
The roots absorb water and minerals from the soil and anchor the plant in the ground. The stem supports the plant above ground, and carries the water and minerals to the leaves. The leaves collect energy from the Sun and make food for the plant, using an amazing process called photosynthesis.
