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. haploid.
c. monoploid.
d. polyploid.
Answer:
The correct answer is a. diploid.
Explanation:
Gametes are haploid entity which contains one genome or one complete set of chromosome a particular organisms. Gametes are represented by (n) and are produce as a result of meiosis in the germ cells during gametogenesis. Fusion or fertilization of a male and a female gamete results into one celled structure called zygote. The zygote receives two genomes one each from a male gamete and a female gametes. Thus, a zygote contains two sets of chromosomes. ( n+n) = 2n or diploid.
Answer:
the cytoplasm is partitioned by the construction of a new cell wall, the cell plate, inside the cell.
Cytokinesis refers to cytoplasm and other organelles are physically separated to create two unique daughter cells. It completes the process of cell division and is the last stage of the cell cycle.
The cytoplasm of the cell, together with all the required organelles and cellular parts, are divided between the two daughter cells during cytokinesis. This guarantees that each new cell will have the framework and resources it needs to operate effectively.
Because plant cells have a cell wall, the specifics of cytokinesis can vary between animal and plant cells. The stiff cell wall in plant cells precludes the same kind of cleavage process that occurs in animal cells. Instead, in the center of the dividing cell, a structure known as the "cell plate" develops. Two distinct plant cells eventually arise as a result of the cytoplasm and other contents of this cell plate being divided as it expands.
Animal cells typically undergo a process known as cleavage in order to undergo cytokinesis. Just below the cell membrane, a protein ring that can contract slowly like a drawstring forms, pinching the cell into two distinct daughter cells.

b.in the center of ocean plains
c.at deep-sea trenches
d.none of the above
Option A, at mid-ocean ridges, is the correct answer.
The topmost layer of the nautical share of a tectonic plate is known as the Oceanic crust. The Ocean Ridge is created as an effect of raising up of magma from the asthenosphere. Mid-ocean ridges are a large, seismically activated submarine elevation system located in the center of the basin of an ocean and considering the situation of the up-welling of magma connected with seafloor expanding. Thus they are as thick as 6 Km at the mid-ocean ridges.
The oceanic crust is thickest at the mid-ocean ridges.
Further explanation:
Oceanic crust is a thin crust that separates the ocean from the mantle, which is present beneath them. The tectonic forces create and destroy the earth's crust. This cycle is essential for all life processes. It helps in forming the earth's crust we walk on and the crust present in the ocean.
Oceanic crust is also known as seafloor. It is denser, thinner, and simpler in structure than the earth's crust. Their fragments become stranded high and dry on top of the continent because of uplift. It is made up of igneous rock basalt. It is formed from the larva that tends to flow smoothly. The basic component of the basalt is magnesium silicate; that is why; it is also known as mafic.

Substrate-level phosphorylation is the process of ATP production via the direct transfer of a phosphate group from a phosphate-containing molecule to ADP, which primarily occurs during the breakdown of glucose.
The production of ATP (Adenosine Triphosphate) by direct transfer of a phosphate group from a phosphate-containing molecule to ADP (Adenosine Diphosphate) is called substrate-level phosphorylation. This reaction generally occurs during the breakdown of glucose in catabolic pathways, where a phosphate group is removed from an intermediate reactant and the free energy of the reaction is used to add a third phosphate to an ADP molecule, thus producing ATP. It is a direct method of ATP regeneration and differs from the other form, oxidative phosphorylation, which involves the use of an electron transport chain and chemiosmosis.

pit
thermo
heat
Answer:
Pit
Explanation:
Pit are one of the organs in rattlesnake that allows them to detect infrared radiation. The other organ that functions in a similar manner is their eyes.
The pit organ acts like a pin hole camera, allowing radiation to pass though its opening and eventually hitting and warming the back wall.
The ability to detect infrared heat radiation enables rattlesnakes to locate its prey in any environmental condition, especially in the dark. Rattlesnake's preys are usually warm blooded, hence, the relevance of the infrared heat radiation detecting pit.
