The given statement is true.
- On one side of the membrane, carrier proteins bind to molecules or ions and release them on the opposite side.
- In order to allow target molecules or ions to diffusely pass through the membrane without interfering with one another, channel proteins make holes/pores that permeate the membrane.
- The specific solute to be transported is bound by carrier proteins (also known as carriers, permeases, or transporters), which then go through a series of conformational changes to move the bound solute across the membrane.
- In contrast, channel proteins have significantly weaker interactions with the solute being conveyed.
- While some channel proteins are always open, others are "gated," which means that they respond to a specific stimulus to either open or close the channel (like an electrical signal or the binding of a molecule).
- Transport proteins known as channel proteins contain a hydrophilic channel via which specific molecules or ions can pass across the membrane (Ex: aquaporins for water). Transport proteins known as carrier proteins bind to molecules and modify their structure to move them across the membrane.

Answer:
a
Explanation:
the reason for a is when a cell is expanding, it divides its self to form a bigger cell, and those cells get close together to from the embryo

Barriers are the circumstances or any other things that hinder the growth and the development of the social and mental state. Intrinsic barriers and learning are types. The problem is the extrinsic barrier.
<h3>What are the barriers and their types?</h3>
An intrinsic barrier is the physical, mental, motivation, and attention-based difficulties. The extrinsic barrier is the outer factor that impedes the learning of the individual and can be due to poverty, economical state, death etc.
Learning difficulty is the problem with educational learning and the methods. This can be due to the low mental quotient, unable to understand and comprehend the study topics.
Therefore, it is an extrinsic barrier.

The presence of paired chromosomes makes a <u>diploid </u>cell, while a single member of a pair of chromosomes makes a<u>haploid </u>cell.
Diploid cells. Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number. </span>
