Hey Sweetie! I'll gladly answer this question for you! I'll give you the answer....

Here it is: The right answer is the option B. Close to 99 percent. The atmosphere is a mixture of gases: nitrogen, oxygen, CO2, H2O, argon, among others. Nitrogen is about 78% and oxygen is about 21%, so they two together constitute about 99 percent of the Earth's atmosphere.

78% of nitrogen, 21% oxygen, and 1% of carbon dioxide and other gases.

Hope I helped you!

Explain how the independent alignment of homologs, and also crossing-over during the first meiotic division, each contribute to

BartSMP [9]

Answer: Homologous chromosomes are randomly distributed to daughter cells, this means different chromosomes segregate independently of each other. And they exchange segments of DNA during crossing over. This recombination creates genetic diversity because genes from each parent are exchanged.

Explanation:

Meiosis is a type of cell division that produces gamete cells, which are sex cells (egg and sperm)

Chromosomes that form a pair and are found together are called homologous chromosomes, and they are inherited from each parent. During prophase of meiosis I, the homologous chromosomes exchange segments of DNA in a process called crossing over. This recombination creates genetic diversity because genes from each parent are exchanged. <u>It results in new combinations of genes on each chromosome.</u>

After that, during the anaphase of meiosis I, the two chromosomes line up on the equatorial plane of the cell. Then, they are separated and each will go to a new daughter cell. So homologous chromosomes are randomly distributed to daughter cells, <u>this means different chromosomes segregate independently of each other.</u>

What happens to glucose during cellular respiration

nekit [7.7K]

Explanation:

During cellular respiration, glucose is broken down and energy is released in the process.

Cellular respiration is a metabolic process by which energy is produced.
In this process, chemical energy stored in the chains of the glucose atoms are transformed into heat energy.
In cellular respiration, glucose combines with oxygen.
The product is the formation of carbon dioxide and water with the release of energy.
This energy is stored in form of ATP.
To be released, one Phosphate is detached to produce ADP.
