A sperm cell of a moth has 112 chromosomes. how many chromosomes are in the moth's wing cells​

Answers

Answer 1
Answer:

Answer:

224 chromosomes

Explanation:

The wing has somatic cells which are formed after successive mitotic division forming diploid cells. On the other hand, the formation of gametes involves meiosis which is a type of reduction cell division that forms haploid daughter cells. Somatic cells have the double number of chromosomes in gamete cells therefore the wing cells have 224 chromosomes.

Answers

Different organisms have a different amounts of chromosomes. Therefore, it is false.

What are chromosomes?

The thread-like chromosomes that convey the genomic information from cell to cell are formed of protein and a single DNA molecule. Chromosomes are found in the nucleus of cells in both plants and animals, including humans.

Each cell's nucleus contains chromosomes, which are structures that resemble threads and contain the DNA molecule. Each chromosome is constructed from DNA that has been tightly wound around proteins called histones numerous times to support its structure.

Not all organisms have the same amount of chromosomes, such as drosophila has 4 chromosomes, humans have 46, a dog has 78 chromosomes and an onion has 16 chromosomes. Therefore, it is false.

False answer because it depends and varies on different types of organisms like we all belong to different phylum, species and everything like we have a classification system basically the answer is no. Genetically it varies too, I would say but again it’s no

What process signals the end of one cycle and the beginning of another in the menstrual cycle

Answers

The menstrual cycle is the set of physiological phenomena, occurring most often periodically (approximately one month), which prepare the body of the woman for a possible fertilization.
The process signal of the end of one cycle and the beginning of a new one is menstruation which is explained by the release of the unfertilized ovule with the placenta precursor (which is a blood).
In the case of fertilization, the menstrual cycles are "paused", and "resumed" after the childbirth.

Why do plants need both a cell membrane and a cell wall?

Answers

Answer:Plant cells are somewhat unique because unlike animal cells, plant cells contain both a cell wall and cell membrane. ... The cell wall is a protective layer outside the cell membrane that also provides support for the cell's structure.

The allele for brown fur (B) is dominant over the allele for white fur (b). What is the probability that an offspring of the cross shown above will have the genotype Bb?

Answers

The probability that an offspring of the cross shown above will have the genotype Bb is 1:2. The correct option is D.

What are alleles?

Alleles are the variations of the gene or trait of an organism. One gene contains a variation of the same type of trait. These traits come to form the mother and the father of the offspring.

They are of two types, the dominating and recessive. The dominating allele is denoted by a capital letter and the recessive gene is denoted by a small letter.

Here, the dominating allele is brown fur, B and the recessive allele is b, white fur. When crossing over happens, there is the probability of having the genotype Bb is 2:4 which will be 1:2.

Thus, the correct option is D. 1:2.
