Answer:

ATP (Adenosine triphosphate)

Explanation:

ATP that is also known as energy currency of the cell is the principal compound which living organisms use to release and store chemical energy. This is because the structure of this molecule which has the ability to store and release enormous amount of energy.

As you can see in the structure of ATP molecule, it consists of one sugar unit ribose, bonded with an adenosie unit at one side and three phosphate atoms at the other side. The phosphate bonds hold tremendous importance for making ATP an energy currency.

The process of release of energy involve the breakdown of phosphate bonds from ATP molecule and is known as hydolysis. The first phosphate bond breakage produces 7 kcal/mole amount of energy while the other ones produce relatively lesser amount of energy as depicted in figure.

When the cell needs energy to perform its activities one phosphate bond is broken from ATP releasing energy stored in the bond that the cell can use to do work and converts ATP to ADP (Adenosine di phosphate).

When cell needs to store energy a phosphate bond is added with ADP and energy is again stored. This is a part of the process of cellular respiration that is key process of producing energy.

<span>When you are pregnant, you do not ovulate because you have already fertilized an egg and it is embedded into the uterus where it is growing into a baby. The body knows this, so it does not shed the uterine lining. The shedding of this lining is triggered by hormones which change when the body is pregnant. During pregnancy, a large amount of progesterone is initially produced which helps to prevent the lining from shedding. If you are not pregnant, your progesterone level will begin to decline at the end of your cycle, triggering the shedding of the lining and the period. Birth control pills alter your hormones to mimic a pregnant state. This will prevent the body from releasing an egg and then shedding the uterine lining.</span>

Do you think the challenge society faces with regard to feeding the world's growing population is an example of ecological carry

Minchanka [31]

Answer: Yes

Explanation:

Carrying capacity can be defined as the total number of members of the population of a species that an ecosystem can sustain in terms of providing resources in the form of food, shelter and others. When the resources are available in surplus then the population of a species increases exponentially but declines when resources become scarce. The human population is increasing tremendously all over the world this is supported by the resources like food, water, fossil fuels, air, minerals, and others. But some of these resources are decreasing due to overuse and may not be available in future to sustain the future generation.

What’s the difference between heal cells and human cells?

Vesnalui [34]

Answer:

HeLa cells, like many tumours, have error-filled genomes, with one or more copies of many chromosomes: a normal cell contains 46 chromosomes whereas HeLa cells contain 76 to 80 (ref) total chromosomes, some of which are heavily mutated (22-25), per cell.
