Answer:

Two homologous chromosomes paired together, each of which has two sister chromatids.

Explanation:

Zygotene stage of prophase I of meiosis I is characterized by the pairing of homologous chromosomes with help of synaptonemal complex. Since DNA replication has occurred in S phase, each chromosome in the pair contains two sister chromatids.  

So, the chromosome pair appears to have a total of four chromatids and the structure is termed as "tetrad".

denis-greek [22]

Schools have to give proper meals and carbohydrates to students.

<h3>What is a balanced diet?</h3>

A small portion of the diet is also set aside for extra nutrients to last through the brief period of leanness. In this situation, we must choose a unique menu that offers the

In this context, we have to first prepare the list of the number of carbohydrates, lipids, and proteins and then we have to identify the maximum amount required in the meal. then observe the common food in the school.

Answer:

Sister chromatids / centromeres: When a single chromosome has been replicated in copies, each copy is called a sister chromatids.

A special part of the chromosome called the centromere holds the two sister chromatids together. A centromere is like a built-in rubber band for two sister chromosomes.

Mother cell / daughter cell: identical.

Daughter cells are genetically identical to the mother cell at the stage of production through mitosis.

On the other hand, at the stage of production through meiosis, the daughter cells are genetically different and contain only half of the genetic material of the mother cell.

Interphase / cell division: A cell spends most of its time in what is called interphase, and during this time it grows,

replicates its chromosomes, and prepare for cell division.

The cell then leaves Interphase, undergoes mitosis, and completes its division.

DNA / chromosome: Genes are segments of deoxyirbonucleic acid (DNA) that contain the code for specific protein that functions in one or more types of cell in the body

Chromosomes are structures within cells that contains a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

Mitosis / cytokinesis: Basically, mitosis is a process by which the duplicated genome in a cell is separated into halves that are identical in nature.

Cytokinesis is the process where the cytoplasm of the cell divides to form two 'daughter' cells. The result is the formation of two 'daughter cells', each having a nucleus.
