The answer is c. Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.

Meiosis is a cell division which results in the reduction of chromosome number by half (from diploid to haploid) in daughter cells. It consists of meiosis I and meiosis II.

In anaphase I, the sister chromatids separate from each other to the opposite sides of the cells. In meiosis I there are 46 chromosomes in duplicates which are present as pairs of sister chromatids. When comes to separation, homologous chromosomes separates only, but not sister chromatids. Homologous chromosomes are present only in meiosis I.

In anaphase II, since the cell is haploid, there are 23 chromosomes in duplicates, which are present as sister chromatids. So, in this phase, sister chromatids are those who separates.

How is carbon exchanged between living and the nonliving parts of the environment?

Ede4ka [16]

Answer:

Carbon dioxide from the air is used to produce food for plant growth. Carbon moves from plants to animals when animals eat the plants. Also, Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere.

The burning of fossil fuels also releases carbon dioxide into the atmosphere.

In a cell containing 10 chromosomes, meiosis results in the formation of daughter cells containing _____ chromosomes.

Sonbull [250]

5 chromosomes. Meiosis results in 4 haploid cells, meaning they have "n" pairs of chromosomes. The diploid cell that the 10 chromosomes originated in has "2n" pairs. This leaves us with a simple equation to solve the problem, 2n=10, so n must equal 5 chromosomes.

How does photosynthesis yield sugar? sumarize how the light-capturing reactions a?

julsineya [31]

Answer
Photosynthesis yield sugar in two main steps

1. Light reaction
In this step plant absorb sunlight which cause photolysis of water and excitation of electron. this electron flow through Z-scheme and atlast enter into NADH, the end product of light reaction is ATP and NADH₂.

2. DArk reaction.
In this step ATP and NADH₂ are used as raw materials. it occurs in stroma of chloroplast. here CO₂ is used through Calvin cycle and at the end glucose is prepared.
