Answer is D) Thalamus
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.

B. Yes, because there is one variable and a control
C. No, because there is not more than one variable
D. No because there is only one variable and a control
Answer:
The correct answer is option B. yes because there are one variable and a control.
Explanation:
The validity of experiments can be tested by the four components of experiments. These four components are control, dependent variable, independent variable, and constants. All of this basic component is the validity of the experiments.
In this experiment there is the control where experiment is performed within controlled and there is also one variable.
Thus, the correct answer is option B. yes, because there are one variable and a control.
Answer:
The correct answer will be option-B.
Explanation:
A scientific experiment must contain three variables: independent variable (which can be manipulated), dependent variable(which can be tested) and control (which is kept constant).
Experimental samples must be divided into two groups: an experimental group in which variable to be studied is tested and a control group in which the independent variable does not influence the experiment.
In the given question, since experimental design contains variables and the experimental as well as the control group which act as a reference group to the experiment.
Therefore, Option-B is the correct answer.
a. True
b. False
