Two interactions within an ecosystem are predation and parasitism. In predation, predator organisms feed on prey organisms. In p

arasitism, parasites depend on host organisms. Which of the following correctly describes the relative numbers of organisms in parasitism or predation?

Answer:Predator-prey relations refer to the interactions between two species where one species is the hunted food source for the other. The organism that feeds is called the predator and the organism that is fed upon is the prey. There are literally hundreds of examples of predator-prey relations.

A single-stranded sequence of DNA is shown.
mojhsa [17]

Answer:

The correct option is (A).

Explanation:

The base-pairing rule illustrates the pairing of purine and pyrimidine bases in the construction of nucleic acids. Adenine and guanine are purines and pyrimidines are cytosine, thymine, and uracil.The total number of base-pair defines the size of the genome of an organism.

Uracil is exclusively present in the RNA. We can infer that purine base pairs with pyrimidine. So, adenine pairs with thymine in the DNA strand with the help of two hydrogen bonds and guanine pairs with cytosine that is supported by the presence of three hydrogen bonds.  

In case of RNA adenine forms double bond with the uracil residue.

When the vasomotor center of our brain wishes to increase blood pressure, it increases ____________ signals causing ______.
dlinn [17]

When the vasomotor center of our brain wishes to increase blood pressure, it increases<u> the heart rate signals </u>causing<u> The greater contraction of the heart causes more blood vessels to constrict, increasing the blood vessels' resistance.</u>

By speeding the heartbeat, making the heart beat harder, and constricting some blood vessels, the sympathetic nervous system increases blood pressure. This will enhance the vessels' resistance.

What controls blood pressure by the vasomotor center?

The vasomotor center modifies the tone of the vascular smooth muscle. Both the local and systemic blood pressure are impacted by this. The vasomotor center produces increased sympathetic tone when blood pressure lowers. This causes an increase in blood pressure.

How is blood pressure regulated?

The autonomic nervous system has short-term control over blood pressure (ANS). Baroreceptors are capable of detecting changes in blood pressure. These are situated in the carotid sinus and aortic arch. High arterial pressure causes the blood vessel wall to stretch, activating the baroreceptors.

What systems regulate peripheral resistance in the vasomotor center?

The vasomotor center in the tunica media regulates smooth muscle contraction or vessel tone. Circulating output is impacted by changes in peripheral resistance, pressure, and flow. The majority of these neurons are in charge of causing sympathetic neurons to release the neurotransmitter norepinephrine.
