Regular human body cells contain a total of 46 chromosomes. Therefore, because of meiosis, sperm cells contain ____ chromosomes.

Nataliya [291]2 years ago

Regular human body cells or somatic cells have a total of 46 chromosomes. Therefore, because of meiosis, sperm cells, which are gametes or sex cells must contain 1/2 of the number of total chromosomes found within a somatic cell, to make sure that the chromosome number within an organism is maintained, this would be 23 in this case.

The stomach<span> is a muscular hollow organ. It takes in food from the esophagus (gullet or food pipe), mixes it, breaks it down, and then passes it on to the small intestine in small portions. The entire digestive system is made up of one muscular tube extending from the mouth to the anus.

Which of the following has the most potential of experiencing background extinction based on the natural disruption described?
Neko [114]

The option that has the most potential of experiencing background extinction based on the natural disruption is : ( C ) A species that will not grow during a specific season every year

<h3>What is Background extinction </h3>

Background extinction is the gradual extinction of species due certian environmental factors such as change in weather conditions, disease, competitive disadvantage and habitat loss.

A population that will not grow during a specific season every year will experiences a gradual extinction process while other options will experience a fast and sudden extinction process.

Hence we can conclude that the most potential of experiencing background extinction based on the natural disruption is :  A species that will not grow during a specific season every year.

During aerobic respiration, the energy within the bonds of a glucose molecule is released in small amounts in a step-by-step, en
Rus_ich [418]

Answer: In this process, the energy released in form of ATP (Adenosine triphosphate) is used to POWER BIOCHEMICAL PROCESSES.

Explanation:

Aerobic respiration is the process by which living organisms breaks down glucose molecule to release energy. Oxygen is used for this process that's why the name aerobic.

Aerobic respiration releases energy within the bonds of glucose step by step in an enzyme controlled reaction. The stages of these processes includes:

--> Glycolysis: In this stage, glucose molecules are split to produce two molecules of ATP and two molecules of NADH (another energy carrying molecule).

--> Krebs Cycle: this is the second stage which occurs in the mitochondria of cells. The 2 ATP molecules generated from glycolysis is used to produce two more ATP, 8 more NADH and 2 molecules of FADH. This makes it a total of 16 energy molecules ( including 2 molecules of ATP from glycolysis).

--> Electron transport chain: this is the last stage of aerobic respiration which takes part at the inner member of the mitochondria. Electrons are transported from molecule to molecule down an electron-transport chain. Some of the energy from the electrons ( NADH and FADH from kreb cycle) is used to pump hydrogen ions across the membrane, creating an electrochemical gradient that drives the synthesis of many more molecules of ATP. As a result 32 more ATP are generated.

In conclusion, a total of up to 36 molecules of ATP from just one molecule of glucose in the process of aerobic respiration which are used to power biological processes.
