Answer:
I think it's parathyroid glands
Answer:
These include the carbon oxides, hydrocarbons, and halocarbons (molecules with carbon bonded to F, Cl, Br, or I).
Explanation:
The Crossover of chromosomes occurs during the prophase 1 phase of meiosis.
<h2>Further Explanation
</h2><h3>Cell division </h3>
- Cell division is the process in which cells within an organism undergoes division to give rise to new cells.
- There are two types of cell division, namely:
<h3>Mitosis </h3>
- Mitosis is a type of cell division that occurs in the somatic cells or the body cells where cells divides to give new cells that are similar to the parent cell.
- The daughter cells have the same number of chromosomes as the parent cells.
- For example in humans the parent cells are diploid, 2n, while the daughter cells are also diploid, 2n. (Diploid means each cell has two pairs of chromosomes).
<h3>Meiosis </h3>
- This is a type of cell division that takes place in the gonads, or reproductive organs, in which cells divide to form daughter cells that differ genetically with the parent cells.
- The daughter cells contain half the number of chromosomes, haploid, n, while the parent contain a diploid number, 2n, of the chromosomes.
- Meiosis occurs in two phases, that is, meiosis I and meiosis II
- During the process of meiosis several processes occurs that cause genetic variation among organisms. These processes include, crossing over, independent assortment of genes, among others.
<h3>Crossing over </h3>
- Cross over is the process that occurs during the prophase I phase of the first stage of meiosis known as meiosis I.
- During the process of crossing over, genetic material is exchanged between homologous chromosomes which enhances the genetic variation in organisms.
Keywords: Cell division, meiosis, mitosis, prophase I, crossing over

Cellular communication is the function of the plasma membrane that allows it to respond to certain stimuli from outside the cell and hormones to bind to receptors.
<h3>What is plasma membrane?</h3>
It is a double layer of lipids that covers and delimits the cells, serving as a border between the inside and the outside of the cell, and also allowing a physicochemical balance.
<h3>Characteristics of plasma membrane</h3>
Enables the development of compartments; allows or rejects the entry and/or exit of particles; acts as a mechanical defense; and reacts to external signals and stimuli.
It reacts and transmits information inside the cell, starting certain biochemical processes: cell division, cell movement or the segregation of biochemical substances.
Therefore, we can conclude that the main characteristic of the plasma membrane, that is, its ability to allow or reject the entry of certain molecules into the cell.
