Blood vessels are connected to nerve fibers which are regulated by the
nervous system. When innervated they respond by doing what?
Answer:
When blood vessels are innervated they respond by contracting and relaxing their muscle wall, as a result of the activity of the autonomic nervous system.
Explanation:
The nerves that are responsible for the innervation of the blood vessels are called nervi vasorum, and are composed of nerve fibers of the sympathetic and parasympathetic nervous systems.
The innervation of the blood vessels specifically acts on the muscular wall of the vessel, so it contracts or relaxes depending on the activity of the nervous system:
Sympathetic nervous system stimulates vascular contraction.Parasympathetic nervous system makes the vascular smooth muscle relax.The action of the autonomic nervous system has an effect on blood pressure, being a determinant of normal or pathological behavior of the arteries.

2. Create a complementary
strand of DNA for the
DNA strand show below.
A T C G T G A
Answer:
T A G C A C T
Explanation:
Adenine (A) and Thymine (T) are base-pairs, alongside Cytosine (C) and Guanine (G). Only A - T or G - C are base-pairs in DNA strands, you will never see Adenine (A) and Cytosine (C) together in a DNA or RNA strand.

(Words may be used more than once)
Carbon atoms enter the child as part of ________________ . These will first be broken into smaller molecules by _____________. These smaller molecules contain the same ____________ energy. The child needs oxygen so that his cells can perform _______________ __________________ . This process transforms _____________ energy into ____________________ . The carbon atoms leave the child in ________ .
Please help
Answer:
Organic molecules
Digestion
Cellular respiration
CO2
Explanation:
Carbon atoms enter the child as part of organic molecules. These will first be broken into smaller molecules by the process of digestion. These smaller molecules contain the same amount of energy. The child needs oxygen so that his cells can perform cellular respiration. This process transforms chemical energy into energy, carbondioxide gas and water. The carbon atoms leave the body of the child in the form of carbondioxide gas through breathing process..

Place the terms into the correct column that describes the reactions of photosynthesis.
Answer:
In the light-dependent reaction, which occurs in the THYLAKOID MEMBRANE of the chloroplast, energy from SUNLIGHT is used to breakdown WATER to release electrons in order to synthesize ATP and NADPH from ADP and NADP+. In a nutshell, the processes involved in this stage are Electron transport chain, photosystem I, photosystem II, and ATP synthase.
- In the light-independent stage, also called CALVIN CYCLE, the ATP, NADPH, and CO2 are used as reactants to synthesize SUGAR (glucose), NADP+ and ADP (which goes back to the first stage) as products.
Explanation:
In the light-dependent reaction, which occurs in the THYLAKOID MEMBRANE of the chloroplast, energy from SUNLIGHT is used to breakdown WATER to release electrons in order to synthesize ATP and NADPH from ADP and NADP+.

- In the light-independent stage, also called CALVIN CYCLE, the ATP, NADPH, and CO2 are used as reactants to synthesize SUGAR (glucose), NADP+ and ADP (which goes back to the first stage) as products.
The light-dependent reactions involve both photosystems I and II along with the electron transport system. ATP is synthesized in this reaction, so ATP synthase is also included.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The light-dependent reaction of photosynthesis occurs in the thylakoid membrane. Sunlight and water are the reactants of this reaction. The products of this reaction are NADPH, ATP, and oxygen.
Light-independent reaction involves the Calvin cycle. It occurs in the stromal part of the chloroplast. The reactants of this reaction are carbon dioxide, ATP, and NADPH while the products are glucose, NADP+, and water.
Therefore, the difference between light-dependent reaction and light-independent reaction is well described above.

How does the size of a bacterial cell compare with an animal cell?
Answer:
hope it helped
Explanation:
Bacterial cells are very small - about 10 times smaller than most plant and animal cells. Most bacterial cells range in size from 0.2 to 10 microns or micrometers (0.0000079 to 0.00039 inches). ... One reason why bacterial cells are so small is that they need a large surface area to cell volume to take in nutrients.
