Answer: Cell division
Explanation:
Cell division can be define as the process by which the parent cell divides into daughter cells. It is the part of the cell cycle.
In multi-cellular organisms there is specialization of cells for performing different functions thus cell division is required for this purpose the cells divide and a mass of cell or tissue performs functions. These functions are necessary for the growth of the organisms.
In uni-cellular organisms the functions are few. Thus a single cell divides to produce multiple cells to produce the offspring. It is the mode of asexual reproduction.
Answer:
23,46
Explanation:
because a gamete is a sex cell that contains half of the genetic material (haploid) as a normal body cell. So in humans, instead of having 23 pairs of chromosomes, a gamete only contains 23 singular unpaired chromosomes. So if you also multiply it by 2 you would get 46
Waves are important for building up and breaking down shorelines. Waves transport sand onto and off of beaches. They transport sand along beaches. Waves carve structures at the shore.
Since there are no given choices, I would just compare and contrast DNA and RNA. These are the two types of nucleic acids in the human body. The structural unit of nucleic acids are composed of repeating units of monomers called nucleotides. Nucelotides are composed of three functional groups: sugars which are specifically pentoses (5-Carbon sugars), phosphate group and nitrogenous base.
Now, the RNA and DNA differ in the composition of these sugars and the bases. Based on the nitrogenous bases and sugar, the DNA has a deoxyribose as the sugar and its 4 bases are adenine, guanine, cytosine and thymine. For RNA, the sugar is ribose while its 4 bases are <span>adenine, guanine, cytosine, and uracil.
They also differ in their structure. </span>DNA is a double stranded β-helix with a long chain of nucleotides. RNA is composed of a shorter chain with a single strand α-helix structure.
Lastly, they differ in their functions. T<span>he DNA is responsible for storing the genetic information while the RNA is responsible for transporting the genetic information to the ribosomes which synthesize proteins.</span>

Answer:</h2>
There are three types of meristems on the basis of position, i.e
- Apical meristem.
- Lateral meristem.
- Intercalary meristem.
<h2>
Explanation:</h2>
A meristem is the tissue present in most plants containing undifferentiated cells, found in zones of the plant where growth can take place. Generally differentiated cells(the cells other than meristems) do not divide and produce of a different type of cells.
Meristems are classified on the basis of their location in the plant:
- Apical meristem - these are the meristems located at root and shoot tips of the plant.
- Lateral meristem - these are the meristems located in the vascular and cork cambia in plants.
- Intercalary meristems - these are the meristems located at internodes, or stem regions between the places at which leaves attach, and leaf bases.
Result: There are 3 types of meristems.
