Which of the following occurs in meiosis but not in mitosis? A) chromosome replication
B) synapsis of chromosomes
C) production of daughter cells
D) alignment of chromosomes at the equator
E) condensation of chromatin

Answers

Answer 1
Answer:

The process that occurs in meiosis but not in mitosis is: synapsis of chromosomes

MEIOSIS AND MITOSIS:

  • Meiosis is a kind of cell division that results in the production of four daughter cells (haploid) that are genetically different from one another.

  • Meiosis occurs in different stages namely: prophase, metaphase, anaphase and telophase.

  • In the prophase stage, homologous chromosomes lie side by side to form a structure called tetrad. This process is called synapsis.

  • Synapsis of chromosomes is unique to only meiotic division and hence, does not occur in mitotic division.

Answer 2
Answer:

Final answer:

The process that is unique to meiosis and not found in mitosis is synapsis of chromosomes, which happens during prophase I of meiosis. This involves the pairing of homologous chromosomes and the formation of tetrads leading to genetic variation.

Explanation:

Among the options provided, the process that occurs in meiosis but not in mitosis is the synapsis of chromosomes (option B). Synapsis happens during the prophase I of meiosis, where homologous chromosomes pair up aligning their genes in a process known as synapsis. This is unique to meiosis and results in the formation of tetrads which eventually leads to genetic variation due to crossing over. In contrast in mitosis which is involved in somatic cell division, homologous chromosomes do not pair up or form tetrads.

The inability to start a pregnancy after having unprotected vaginal intercourse for more than a year or the inability to stay pregnant for the full length of a normal pregnancy is?

Answers

The given condition is termed as Infertility.

The infertility can be defined as the condition, in which the woman is not able to produce the young ones. This condition can be characterised by the absence of pregnancy, when no protection is used during intercourse or not able to stay pregnant. This condition can be a result of the fault in the reproductive system of the woman.

The inability to start a pregnancy after having unprotected vaginal intercourse for more than a year or the inability to stay pregnant for the full lengthof a normal pregnancy is called infertility. I hope that this is the answer that you were looking for and it has actually come to your help.

During digestion, carbohydrates are converted by enzymes into

Answers

During digestion, carbohydrates are converted by enzymes into monosaccharides.

What are monosaccharides?

Monosaccharides are the simplest form of carbohydrates. They are composed of a single sugar molecule. The most common monosaccharides are glucose, fructose, and galactose.

Carbohydrates are broken down into monosaccharides through a process called glycolysis. Glycolysis is a series of chemical reactions that occur in the cytoplasm of cells. The reactions of glycolysis break down carbohydrates into smaller molecules, releasing energy in the process.
