Mitosis and meiosis similarities

Answers

Answer 1

Answer:

The alternation of generations in the life cycle of a plant includes the diploid and haploid multicellular stages. diploid and haploid are copies of the chromosomes. The spores in the plant is unicellular and when they start dividing through mitosis, it produces identical cells. These identical cells are all haploid. Haploid stages contain one set of chromosome from either of the parent. These identical cells create a multicellular system called the gametophytes. A gametophyte is the haploid multicellular stage in the life cycle of a plant. The gametophyte makes the gametes. These gametes are responsible for sexual fertilization. It takes place when a sperm (male gametes) from the male fuses into the egg cell (female gametes) of the female. The formation of both male and female gametes creates a diploid zygote. Diploid stages contain one set of chromosome from each parent. This is where the sporophyte comes in. A sporophyte is the diploid multicellular stage in the life cycle of the plant. It now contains the two sets of chromosomes from each parent.

The type of cell division that produces gametes with half the normal chromosome number is the meiosis. Meiosis is the type of cell division used in sexual reproduction. It will occur in the testes and ovaries.

The Redwood trees in Oregon are huge. They increase their size and weight by___ A. binary fission B. multiple fission C. mitosis or D. meiosis

Answers

Answer:

(C). mitosis.

Explanation:

In multicellular organisms, mitosis is responsible for the growth, repair, and enlargement of organism, by producing more number of new identical cells. Mitosis is a type of cell division that involves formation of two similar daughter cells from a parent cell.

The Redwood tree is an eukaryotic, multicellular plant, in which growth and development occurs by the mitosis. Hence, the process that would increase the weight and size of Redwood trees is mitosis.

Thus, the correct answer is option (C).

D. is most likely the answer

An organism is homozygous dominant for one trait and heterozygous for another. A scientist uses this organism in a dihybrid cross. How many different allele combinations can the organism produce for these traits in his or her gametes

Answers

Basically there are only 2 unique different allele combinations that this organism can produce in their gametes for these traits. They are AB and Ab.

The process of making RNA from a DNA sequence is called

Answers

The process of making RNA from a specific sequence of DNA is called the process of Transcription. It is the first part of Protein Synthesis in Eukaryotic Organisms. (In prokaryotes, transcription and translation occur simultaneously).

Final answer:

The process of making RNA from a DNA sequence is called transcription.

Explanation:

The process of making RNA from a DNA sequence is called transcription. During transcription, a gene on the DNA molecule is transcribed into a complementary mRNA molecule. This mRNA molecule carries the genetic information encoded in the DNA and serves as a template for protein synthesis.
