Answer:
<em>The number of chromosomes is maintained through the process of mitosis during asexual reproduction. </em>
Mitosis can be described as a process in which a cell divides and produces two daughter cells which are exactly similar to the parent cell. The chromosome number of the daughter cells will be the same as the parent cells. No crossing over or recombination occurs during this type of cell division. Hence, mitosis is an effective way to maintain the chromosome number of organisms which reproduce asexually.
<span>DNA replication is the production of identical DNA helices from a single double-stranded DNA molecule. Each molecule consists of a strand from the original molecule and a newly formed strand. Prior to replication, the DNA uncoils and strands separate. A replication fork is formed which serves as a template for replication. Primers bind to the DNA and DNA polymerases add new nucleotide sequences in the 5′ to 3′ direction. This addition is continuous in the leading strand and fragmented in the lagging strand. Once elongation of the DNA strands is complete, the strands are checked for errors, repairs are made and telomere sequences are added to the ends of the DNA.</span>
I think the correct answer among the choices listed above is the first option. The function of the nucleus is to store DNA. Majority of a cell's genetic material is found in this organelle. It is a characteristic of eukaryotic cells. Hope this answers the question.
Scientists use this because it makes very large or very small numbers easier to work with.
An example of scientific notation would be instead of writing 0.0000000056, we write 5.6 x 10^-9
The epidermis is the remotest subcaste of cells generated from the protoderm that covers the stem, root, splint, flower, fruit, and seed sections of a factory. The moldable cuticle of the epidermis acts as a hedge against infection, water loss, and mechanical detriment.
<h3>What about epidermis?</h3>
- Botanically speaking, the epidermis is the face, single- layered caste of cells that covers a plant, particularly the flake and immature vascular plant corridor like stems and roots.
- In vascular shops, the dermal napkins are called epidermis and periderm.
- The barricade separating the plant from the outside world is the epidermis.
- Pavement cells, guard cells, and the attachment cells that compass the stomata and trichomes, sometimes known as flake hairs, are the three introductory cell types that make up the plant epidermis.
- Conical cells, a kind of trichome, are also formed in the epidermis of petals.
- The cuticle, a functional permeability barricade of the cell wall that inhibits devilish water loss and the entry of dangerous agents and pathogens into the host, is formed by the plant epidermis and serves as its primary function.
- The epidermis is the flake's outermost caste.
- On either side of the flake, the top and lower epidermis make up this caste.
- Botanists designate the undermost side as the abaxial face and the upper side as the adaxial face.
- Gas control is backed by the epidermis.
