organize at least seven of your body's cell processes that require energy
Answer:
search up the question and you find lots of accurate results
Energy is required for a variety of vital biological and cellular functions, including ATP hydrolysis. These include active transport, Purinergic signaling, synaptic signaling, intracellular signaling, DNA and RNA synthesis, and muscular contraction.
What do you understand by cell ?
The fundamental units of all living things are cells. There are many billions of cells in a human body. They provide the body structure, absorb nutrients from meals, turn those nutrients into energy, and perform certain tasks.
Adenosine triphosphate molecules directly provide the energy needed for cellular functions (ATP). One adenosine molecule and three phosphate groups, or Pi for short, make up ATP. The chemical energy that is stored in each ATP molecule is not very large. By dissolving ATP into adenosine diphosphate (ADP) and a phosphate group, this energy may be released.
The energy process include active transport, Purinergic signaling, synaptic signaling, intracellular signaling, DNA and RNA synthesis, and muscular contraction.

Why is it important for DNA replication to be a
highly regulated process?
Answer:
Here you go
Explanation:
DNA replication is regulated to ensure all chromosomes replicate once and only once per cell cycle.Cell cycle regulation by protein phosphorylation ensures that pre-RC assembly can only occur in G1 phase, whereas helicase activation and loading can only occur in S phase.

What are two external conditions that must be
met for a seed to sprout?
Answer:
Temperature, water and oxygen.
Explanation:
There are 3 answers yes, but any 2 of them should work.
Answer:
I will give all the external conditions, you can choose 2 of them <3
Explanation:
All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also. Some germinate better in full light while others require darkness to germinate. When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat.
I suggest you choose water and oxygen

The government wants to set new regulations that prohibit chlorofluorocarbons (CFCs) use in aerosol sprays and refrigerants. How will this act help with the sustainability of our environment?
Answer:
The new regulation will help reduce the amount of green house gases available in the atmosphere thereby saving our environment from the Green house effect
Explanation:
Chlorofluorocarbons are examples of greenhouse gases which contribute to the Green house effect been experienced in our environment, by destroying the earths' Ozone layer
If the Government sets a new regulation that prohibit its use in sprays and refrigerants it will help reduce the amount of green house gases available in the atmosphere thereby saving our environment from the Green house effect
Answer:
that act will help the sustainability of out environment because : C. It will slow down the degradation of the ozone layer
The usage of CFC will crate chlorine atoms that catalyze ozone degradation. By prohibiting this product, Government will slow down Ozone's degradation

In response to a decrease in tissue metabolic activity, tissue oxygen concentrations ________, which causes a(n) ________. In response to a decrease in tissue metabolic activity, tissue oxygen concentrations ________, which causes a(n) ________. increase : active hyperemic response decrease : dilation of the arterioles decrease : increase in tissue ischemia decrease : active hyperemic response increase : constriction of the arterioles
Answer:
The correct answer is - increase: constriction of the arterioles.
Explanation:
When the physical activity is decreased by the tissues of the muscle, the oxygen concentration in the tissue increases which leads to the constriction of the arterioles.
It takes place in order to decrease blood flow and blood pressure as oxygen requirement is less in the tissue in decreased physical metabolic activity. The constriction of arterioles results in more resistance to decrease the blood flow in capillaries.

2. What are fossils? How are fossils used to explain evolution?
Answer: 1. Embryology, the study of the development of the anatomy of an organism to its adult form, provides evidence for evolution as embryo formation in widely-divergent groups of organisms tends to be conserved. ... Another form of evidence of evolution is the convergence of form in organisms that share similar environments. 2. Fossils are the preserved remains or traces of animals, plants, and other organisms from the past.
