Answer:

The correct answer will be option

1. Oxygen

2. water.

Explanation:

Electron transport chain is the final step of the aerobic respiration which takes place in the inner mitochondrial membrane.

This chain helps in the formation of the ATP molecules as it is embedded with the ATP synthase.

The aerobic respiration is called the aerobic respiration as it uses the oxygen only in the final step of the ETS where oxygen combines with the free hydrogen ions to form metabolic water.

dem82 [27]

Answer:

c. Two sister chromatids did not separate into the proper daughter cells during anaphase.

Explanation:

The observed cell is undergoing mitosis which does not include separation of homologous chromosomes. During anaphase of mitosis, two sister chromatids of each chromosome separate from each other. They move to opposite poles. This results in equal distribution of two complete sets of chromosomes to each daughter cell.

However, the failure of two sister chromatids of a chromosome during anaphase would lead to the formation of two abnormal daughter cells. One of the daughter cells would have one extra chromosome (2n+1) while the other would lack one chromosome from the diploid set (2n-1).

Stella [2.4K]

Answer:

The amount of organic matter in mineral (sand, loam or clay) soils ranges from very low being 1% by weight, to average being 2 to 4%, and high being greater than 5%. There are also “muck” or organic or peat based soils that are 30 to 40% organic matter. The general consensus is the more soil organic matter the better.   approximately 45%
