Answer:In many ways, meiosis is a lot like mitosis. The cell goes through similar stages and uses similar strategies to organize and separate chromosomes. In meiosis, however, the cell has a more complex task. It still needs to separate sister chromatids (the two halves of a duplicated chromosome), as in mitosis. But it must also separate homologous chromosomes, the similar but nonidentical chromosome pairs an organism receives from its two parents.

Explanation:Mitosis(Opens in a new window)(Opens in a new window) is used for almost all of your body’s cell division needs. It adds new cells during development and replaces old and worn-out cells throughout your life. The goal of mitosis is to produce daughter cells that are genetically identical to their mothers, with not a single chromosome more or less.

Meiosis, on the other hand, is used for just one purpose in the human body: the production of gametes—sex cells, or sperm and eggs. Its goal is to make daughter cells with exactly half as many chromosomes as the starting cell.

To put that another way, meiosis in humans is a division process that takes us from a diploid cell—one with two sets of chromosomes—to haploid cells—ones with a single set of chromosomes. In humans, the haploid cells made in meiosis are sperm and eggs. When a sperm and an egg join in fertilization, the two haploid sets of chromosomes form a complete diploid set: a new genome.

Explain how the terms oxidation and reduction apply even when there is only a partial shift of electrons between atoms linked by
aliina [53]

Explanation:

In a covalent bond, there is sharing of the donated electron by two atomic species having very small electronegative differences between them.

Oxidation is the loss of electrons by a specie and it usually lead to an increase in oxidation number.

Reduction is the gain of electrons by a specie. It leads to a lower oxidation number.

Since there is no actual loss of gain of electrons in a covalent body, the electronegativiy is at work.

Electronegativity is the ability of a specie to draw the shared electrons more to itself in a covalent bond.

  • Between two atoms bonded covalently, the more electronegative specie draws the electrons closer.
  • This leaves a partial negative charge on it.
  • The other electron then becomes partially positively charged.
  • We can then say, the more electronegative specie undergoes reduction.
  • The less electronegative one undergoes oxidation.

Draw the structure of DNA aand write a short note about it.​
artcher [175]

Answer:

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.

A cell is a complex system. Like most systems, a cell contains a boundary that separates things that are inside the system from
bearhunter [10]

Answer;

Cell membrane


A cell membrane acts as a boundary that separates things that are inside the system from those that are outside the system.

Explanation;

It is a thin semipermeable structure that surrounds the cytoplasm of a cell.

The membrane functions to protect the integrity of the internal environment of the cell by allowing selective movements of materials in and out of the cell.

The membrane consists of a phospholipid bilayer with proteins embedded in it.

ATP is a compound that is synthesized when
Reil [10]
ATP, also called adenosine triphosphate or the body's energy currency, is a compound that is synthesized when we have a compound called adenosine diphosphate (ADP). When this compound gets another phosphate group (P) attached, we get the more known ATP. This is also why the name changes from diphosphate to triphosphate (di - two, tri - three).
