The right answer are in the picture attached.
Gametes:
A gamete is a sexual cell that allows sexual reproduction. The word gamete comes from elsewhere in ancient Greek and means "spouse".
Gametes function to merge to give birth to a new individual with unique genetic heritage.
The random loss of a chromosome of each pair allows the fertilization of two gametes with each other, whose fusion will give birth to an egg (zygote) endowed, like its parents, with 46 chromosomes.
Meiosis:
* Meiosis consists of two successive cell divisions that will give birth to gametes.
At the end of meiosis, the original cell gave birth to four haploid cells whose genomes were recombined in a unique way.
* In humans, the cells that will participate in meiosis are spermatocytes and oocytes.
* In the cells that will enter into meiosis, the replication of A.D.N. occurred during interphase, each chromosome consists of 2 chromatids connected by their centromere. (Each chromatide is composed of a double-stranded A.D.N molecule and molecules that maintain its structure).
Mitosis:
Mitosis is the process of reproducing (identical) cells.
At the end of the mitosis, the mother cell divided into daughter cells identical to each other and identical to the cell that gave birth to them.
This one can be broken down into 4 phases.
Prophase, Metaphase, Anaphase and Telophase.
Somatic cells:
The set of somatic cells, called soma, are all the cells forming the body of a multicellular organism, that is, all non-germline cells, such as gametes, or cells. germ. These last ones constitute the germen.
Somatic cells are usually the vast majority of cells that make up an individual.
Asexual reproduction (there's no asexual cells in the proposed terms):
A vegetative or asexual cycle, in the context in which this word is used here, means: which does not concern reproduction but which concerns the physiological processes that ensure life, growth, development and multiplication when it is not sexual .
A vegetative or asexual cell is said to be, as opposed to reproductive, a cell whose function is related to nutrition. See the definition of endospore and especially vegetative propagation.
Sexual reproduction (there's no sexual cells in the proposed terms):
Sexual reproduction is a reproductive process that creates a new organism by combining the genetic material of two different sex organisms through a different genital reproductive tract in both males and females. This process occurs in both eukaryotes and prokaryotes; in multicellular eukaryotic organisms, a new individual is created; in prokaryotes, there is scissiparity of the initial cell.
Somatic cells undergo mitosis for growth and form asexual cells. Gametes, produced through meiosis, are reproductive or sexual cells. Mitosis produces identical copies of cells, while meiosis produces gametes for sexual reproduction.
In understanding cell division, we need to look at four main terms: gametes, meiosis, mitosis, and somatic cells. Somatic cells are non-reproductive cells that undergo mitosis for growth and repair, leading to asexual cells, while gametes are reproductive cells (sexual cells) created through meiosis. Mitosis and meiosis are types of cell division. Mitosis divides a cell into two identical copies and is a key mechanism of asexual reproduction. On the other hand, meiosis is involved in sexual reproduction and generates gametes.

A) dissolve in water
B) be more permeable
C) lose its water
D) be less permeable
If the fatty acids of the cell membrane were completely saturated, a cell would be more permeable. Thus, the correct option is B.
A cell membrane may be defined as a biological membrane that untangles the interior of all cells from the external environment and shields the cell from its environment.
The presence of saturated fatty acids increases the membrane permeability due to the presence of only single bonds. It increases the transport of molecules between the inner and outer compartments of the cell.
Therefore, the correct option for this question is B.

The following choices are given;
A. XrXr. B. XrY. C. XRY D. XRXr
The answer is B. This is because the presence of the Y chromosome determines gender- which is male. In addition, it carries few genes than the X sex chromosome. Therefore, in this case, the X chromosome brings in the receive allele for eye color while the Y chromosome has no corresponding allele.
In most diploid organisms, they are two types of alleles for most genes which each on each set of chromosomes and at the same loci. In most cases, one allele is dominant over the other meaning that its presence masks the effect of the recessive allele. In the absence of the dominant allele, the recessive allele is expressed . Usually, the recessive gene is disadvantageous to the individual.

Answer:
DNA molecule
Explanation:
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Answer:
The correct answer is "Both secrete mucus".
Explanation:
Goblet cells are specialized cells found mainly in the epithelial lining of intestinal and respiratory tracts, which main function is to secrete mucus by secreting gel-forming mucins. On the other hand, cilia is a protuberance found in cells that serves as a sensory organelle, which can have motility. One characteristic that cilia and goblet cells have in common is that both secrete mucus. Cilia is found in airway cells and helps to move mucus up and out of the lungs.
