Alexxandr [17]

"Eukaryote" roughly translates as "truly nucleated" and refers to organisms with a membrane-bound nucleus.

Such membrane-bound organelles are thought to have arisen via the invagination of the cell's own plasma membrane.

Other organelles such as the mitochondria and the chloroplast are believed to have once existed as separate organisms, but which were engulfed by other cells, forming a symbiotic relationship.

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.

Is there any type of ecological relationship between wolf and moose populations on Isle Royale? If not, explain why not. If so,
Cerrena [4.2K]

The Prey-Predator relationship is the type of ecological relationship between wolf and moose populations on Isle Royale.

<h3>What do you mean by Ecological relationship?</h3>

The Ecological relationship may be defined as the interaction between the members of one species with respect to the members of the other in response to food, shelter, and space.  

Moose are herbivores and the prey of wolfs. It is clearly seen in the graph that when the population of wolves increases, the number of moose decreases. It states that wolfs feed on moose.

Therefore, the Prey-Predator relationship is the type of ecological relationship between wolf and moose populations on Isle Royale.

dusya [7]

Answer:

Through natural selection the disease gain immunity to the antibiotic.

Explanation:

As the antibiotic  kills off the members of the population that are not resistant, leaving only the resistant members. These members then reproduce, passing the immunity to their offspring, causing the population to become immune.

What is the difference between relative and radiometric dating and why is radiometric dating more accurate?
bonufazy [111]

Answer:

The main difference between relative dating and radiometric dating is that relative dating is the method used to determine the age of rock layers according to their relative depth whereas radiometric dating is the method used to determine the absolute age with the use of decaying products of the natural radioactive. Also, absolute dating is more precise than relative dating because it tells the exact age of the fossils. Both are ultimately based on the fossils found in the strata.
