why does your body release a little bit of energy with each step rather than all at once?
In has been observed that during the process of cellular respiration, electrons from glucose move gradually through the electron transport chain in the direction of oxygen, passing to the lower energy states and releasing energy at each step.
How glucose used in cellular respiration?During the process of aerobic cellular respiration, glucose reacts with the oxygen which leads to form ATP ( Adenosine triphosphate) that has to be used by the cell. Carbon dioxide and water has been created as the byproducts. The overall equation for the process of aerobic cellular respiration is that during cellular respiration, glucose and oxygen react in order to form ATP ( Adenosine triphosphate).
Adenosine triphosphate has known as an organic compound which provide energy to living organisms to drive many operations in living cells such as contraction of molecule, muscle pumps, nerve impulse propagation, condensate dissolution, and chemical synthesis.
The energy consumed by the animals in the form of glucose has been conserved because it is transformed into the chemical energy as the carbon dioxide has been produced during the respiration.
Therefore, In has been observed that during the process of cellular respiration, electrons from glucose move gradually through the electron transport chain in the direction of oxygen, passing to the lower energy states and releasing energy at each step.

a hormone that can lower blood levels of calcium ion is
Answer: Calcitonin
Explanation:
When calcium levels in the blood is low, Parathyroid hormone is released to increase it. On the other hand, when calcium levels are high and need to be decreased, Calcitonin is secreted.
Calcitonin acts in opposition to PTH by inhibiting osteoclasts (a cell from which bone develops), stimulating osteoblasts, and increasing the excretion of calcium into the urine by the kidneys. [lumencandela]

A High average temperatures
B High average rainfall
C Low average rainfall
D Low average temperatures
Answer:
low average temperatures
Explanation:
low average temperatures so the dog doesn't overheat
Answer:
The answer should be D.

The phospholipid bilayer is composed of fats with Hydrophobic core. If protein channels were absent in the cell membrane, would water soluble nutrients be able to enter or
exit the cell? Explain in terms of the composition of the plasma membrane. In your own words, explain the fluid mosaic model proposed by Singer and Nicholson.
Without the nuclear membrane the cell would collapse and die. Without the cell membrane, any chemical would be allowed to enter. Membranes are very important because they help protect the cell. Materials move across the membrane by diffusion.

During fertilization in Choose... two fertilization events take place. One fertilization produces the choose... . Another fertilization event produces the Choose... that nourishes the seedling as it grows.
Answer:
angiosperms
Zygote
Endosperm
Explanation:
During fertilization in angiosperm, two fertilization events take place. One fertilization produces the zygote another fertilization event produces the endosperm that nourishes the seedling as it grows.
What is the fertilization process in angiosperms?Angiosperms are characterized by a double fertilization event in which one fertilization produces the zygote and the other produces tissue, called endosperm, within the seed.
After double fertilization, a post-fertilization event occurs, that specify triple fusion, the PEN (primary endosperm nucleus) then grows into the endosperm.
Therefore, in this event, one sperm fuses with the egg to form the 2n zygote, and the other sperm fertilizes with two polar nuclei to create the 3n endosperm is known as double fertilization.

Explanation:
Answer:
A. ( answer)
Enzymes break the hydrogen bonds between the nitrogenous bases to separate the two strands of DNA.
Explanation:
DNA replication involves several different enzymes. Enzymes break the hydrogen bonds between the nitrogenous bases to separate the two strands of the DNA molecule. Then an enzyme called DNA polymerase joins individual nucleotides together to form the new complementary strands of DNA. Lastly, the DNA polymerase "proofreads" each new strand to make sure that each DNA molecule is perfect, or a nearly perfect copy of the original molecule.
