Answer:

Photosynthesis and cellular respiration are essentially opposite processes.

Explanation:

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Both use one another's products to make their own.

I would appreciate brainliest, if not that's ok!

Chromosomes only exist inside gametes true or false

netineya [11]

The male human has a sperm cell and the female has an egg cell. The cells from the male and female that combine to form a zygote are called gametes. The human sperm and egg cells each contain 23 chromosomes. . A combination of gametes forms a zygote with 46 chromosomes. 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.Chromosomes get shuffled when eggs and sperm are made. Though most adult cells contain two sets of chromosomes, sperm and egg cells are different. These special cells have just one chromosome from each pair. Which chromosome they get from each pair is random, making each sperm or egg cell unique. There is also a bit of mixing before the chromosomes are sorted into individual sperm or egg cells. Chromosomes from each pair in a mother or father, respectively, make contact and exchange pieces of DNA, creating hybrid chromosomes.

A pair of mice are bred several times generating the following data table. What are the most likely genotypes of the parents?

Tamiku [17]

Answer:

This question lacks options, the options are:

A) FF and ff

B) FF and Ff

C) Ff and Ff

D) Ff and ff

The answer is D (Ff and ff for parent 1 and 2 respectively)

Explanation:

This question depicts a single gene coding for fur colour in mice. The gene controls two traits, black fur and white fur, encoded by alleles F and f respectively.

According to the question, a pair of mice has been bred several times to generate the same data of 22 black fur and 23 white fur mice. Based on this data, it shows that the phenotypic ratio of black to white mice is 1:1.

To get a 1:1 phenotypic ratio of black fur offspring to white fur offspring, the parents mice must have genotypes Ff (heterozygous) and ff (same recessive alleles).

In a cross between parents Ff × ff (see punnet square), offsprings with the following genotypes will be produced: Ff, Ff, ff and ff. Ff is black furred while ff is white furred.

Ff (2) : ff (2) is equivalent to Ff (1) : ff (1).

Hence, a data of 22 black mice and 23 white mice which represents a 1:1 ratio will only be produced by parents mice with genotypes: Ff and ff.
