What is the sympathetic nervous system and what are some of the effects it has on the body?

Alex Ar [27]

Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). The sympathetic nervous system (SNS) releases the hormones (catecholamines - epinephrine and norepinephrine) to accelerate the heart rate.

Which are specific to just prokaryotes, or just plants, or just animals? drag the appropriate items to their respective bins. he

balu736 [363]

<span>Prokaryotes have magnetite-containing structures, nucleoid (their version of a nucleus), fimbriae. Animals have lysosomes. Plant cells have chloroplasts (make the plant cells green, produce energy for plants), photosynthetic membranes (produce energy for plants), cell well. Flagella can be found in prokaryotes and animal cells but for a simpler biology class, I would put it with prokaryotes.</span>

Which statement about organism classified in the same genus is true?

notsponge [240]

Genus represents taxonomic rank above species and below family. When organisms belong to the same genus, they must be of the same phyla, but may be in different species. In binomial nomenclature it is the generic name shared by the group of close relative.

photosynthesis and cellular respiration both use electron transport chains. what is the source of electrons for photosynthesis a

goldfiish [28.3K]

Water serves as an electron source in the electron transport process of photosynthesis. The electron is extracted from water by using solar energy.

What is the electron transport chain's source of energy?

The electron transport chain uses the energy released by oxygen and reduced compound reactions such as cytochrome c and (indirectly) NADH and FADH2 to pump protons into the intermembranous space, producing the electrochemical gradient over the inner mitochondrial membrane.

In photosynthesis, water is split to produce electrons in the presence of sunlight, a process known as the photolysis of water. The electrons are finally transferred to NADP+ by the chloroplast electron transport chain, where they are reduced to NADPH.

Therefore, In aerobic respiration, electrons from NADH and FADH2 are transferred to oxygen by the mitochondrial electron transport chain to reduce oxygen in the water.

inn [45]

Question: Based on the model presented, which of the following statements expresses the proper relationship between osmolarity, ADH release, and urine production?

(A) As tissue osmolarity rises, more ADH is released, causing less water to be excreted as urine.

(B) As tissue osmolarity rises, less ADH is released, causing less water to be excreted as urine.

(C) As tissue osmolarity rises, more ADH is released, causing more water to be excreted as urine.

(D) As tissue osmolarity rises, less ADH is released, causing more water to be excreted as urine.

Answer:

As tissue osmolarity rises, more ADH is released, causing less water to be excreted as urine.

Explanation:

ADH is the hormone that triggers the formation of concentrated urine by stimulating the absorption of water from the filtrate in the kidneys. As the solute concentration (osmolarity) in the blood raises, the more of the ADH is released into the blood. ADH triggers reabsorption of water in collecting duct and distal tubules and thereby, reduces the water loss in urine. Increased reabsorption of water restores the osmolarity, blood volume, and blood pressure.
