Which of the following is an example of the endocrine system maintaining homeostasis? (3 points)
-Detecting a pain stimulus and sending a signal to the spinal cord to perform an automatic response
-Discharging an excessive amount of hormones in the blood and not sending a signal to stop production
-Sending a message to the pituitary gland to start producing a hormone when the levels in the body are too low
-Using sense organs to get information about the outside world and direct an appropriate body response release
Answer:
-Discharging an excessive amount of hormones in the blood and not sending a signal to stop production
Explanation:
Endocrine system is regulated by negative feedback mechanisms that work to maintain homeostasis.
Concentration of hormones, and how they effect other body systems, are controlled in this manner.
For instance, the blood glucose regulation is controlled by insulin and glucagon, hormones produced by the pancreas.
Which of the following statements best describes the importance of
nutrient cycling?
Answer:
Since there are no choices to this question, I think it restores ecosystems or the organisms physical environment to a state called the "Equilibrium State".
Explanation:
The Equilibrium State keeps the ecosystems functioning. Nutrient cycles link or put the living organisms with the non living organisms together throughout the flow of the nutrients in the cycle. Remember that living and non living organisms always depend on each other.

Answer:
a. the blood pressure decreases. the bblood in the A that is the artery is higher as the artery carries the oxygenated blood which is directly pumped out of the heart.so the artery's pressure is higher where as the capillaries pressure decreases when compared with artery. the blood in the capillary flows slowly and smoothly as capillary needs time to exchange the substance between the body cells and the blood. the vein carry the deoxygenated blood back to the heart so their pressure is low.
b.the highest pressure is found in the artery because it carries the oxygenated blood and the heart pump the blood with great force thus tge artery have the highest pressure . and it also wanted to transport the oxygen quickly to other parts of the body.
c. valves. these prevent the backflow of the blood in capillary as the blood moves against the gravity.so valves prevent the blood from going back . therefore the valves help the blood in veins to move back to heart. (not sure)

An ecosystem engineer can cause a cascade of effects including abiotic and biotic changes.
O True
False
Answer:
O True
Explanation:
Ecosystem engineers are able to modify the surrounding environment, either by creating new habitats or modifying/destroying existing ones to adjust them to their needs. These species can significantly alter their environments, having a large impact on the species richness as well as modifying the availability of abiotic factors (e.g., water, space, etc) of a particular area. In certain environments, ecosystem engineers can even act as keystone species. Some examples of ecosystem engineers include, among others, beavers, woodpeckers, corals, etc.

The extensive size of the fires that burned Yellowstone National Park in 1988 caught both land managers and ecologists by surprise. Many forests suffered intense infernos that removed virtually all vegetation. Some speculated that the park would never recover. Based on what you learned and disturbance and succession, is it likely that the park was irrevocably altered
Answer:
It is not possible that the park has been irrevocably altered.
Explanation:
The fires are part of the ecology of Yellowstone National Park, and there is a very low risk that this park will be irreversibly modified after a fire. It is scientifically proven that Yellowstone has recovered from fires in a period of thirty years and that the risk of this recovery not happening is very low. In addition, the natural fires that occur in Yellowstone are, in a way, important for the maintenance of the park's ecosystem, since they are able to break the seed dormancy that are in the soil, in addition to promoting the opening of the serine pine cones.
Seed dormancy is the difficulty of germinating that some seeds present, even in an environment with favorable conditions for germination.

In plant and animal adaptations, form follows function. True or false?
Answer:
FALSE
Explanation:
In plant and animal adaptations, form follows function. it is true because all forms of organisms give adaptive advantages.
AdaptationLiving beings tend to have adaptations according to the environment in which they live. Plants in hot and dry climates generally have their leaves reduced, or even modified into thorns, as a way of reducing the contact surface and thus avoiding transpiration.
Whit this information, we can conclude that in plant and animal adaptations, form follows function. it is true because all forms of organisms give adaptive advantages.

Why does the mass of a substance remain the same after a chemical reaction
Answer:
Even in a chemical reaction when atoms interact and create new products, mass is conserved. This is because the new substances created are composed of atoms that were present in the reactants. The atoms from the reactants come apart, rearrange, and re-bond in a different arrangement to form the products.

Explanation:
Extensive damage to oligodendrocytes in the CNS could result in reduced speed of nerve impulses. a breakdown of the blood-brain barrier. loss of the structural framework of the brain. inability to produce scar tissue at the site of an injury. decreased production of cerebrospinal fluid.
Answer:
Loss of the structural framework of the brain.
Explanation:
Damage to oligodendrocytes in the central nervous system leads to the loss of the structural framework of the brain. oligodendrocytes produce the insulating sheath of axons and we know that axons are the nerve fiber that conducts electrical impulses away from the neuron's cell body. Axons are the primary transmission lines of the nervous system that carries impulse throughout the body so if the oligodendrocytes are damaged then our brain did not work properly.
If oligodendrocytes are damaged, the myelin sheaths around axons can be destroyed. This can lead to a loss of the structural framework of the brain, as the axons will no longer be properly insulated. Hence option C is correct.
Oligodendrocytes are glial cells in the central nervous system (CNS) that are responsible for myelinating axons. Myelin is a fatty sheath that surrounds axons and helps to speed up the conduction of nerve impulses.
The loss of the structural framework of the brain can cause a variety of neurological problems, including:
Reduced speed of nerve impulses. As mentioned above, myelin sheaths help to speed up the conduction of nerve impulses. Without myelin sheaths, nerve impulses will travel more slowly, which can cause problems with coordination, movement, and sensation.
Increased risk of seizures. Seizures are caused by abnormal electrical activity in the brain. When the myelin sheaths around axons are damaged, it can increase the risk of seizures.
Cognitive impairment refers to a decline in thinking and memory skills. Damage to oligodendrocytes can lead to cognitive impairment, as the axons will no longer be able to function properly.
Therefore, option C) loss of the structural framework of the brain is correct.

Which of the following is an example of primary succession?
A. the recovery of Yellowstone National Park following the fires of 1988
B. the appearance of lichens and mosses in an area where a glacier has recently melted away
C. the growth of weeds in a field after a farmer stops using the field
D. the growth of weeds in an empty lot that is no longer being mowed
Answer:
B. the appearance of lichens and mosses in an area where a glacier has recently melted away
Explanation:
Ecological succession, which refers to the series of changes that occurs over time in an ecosystem, can be of two types namely: primary succession and secondary succession.
Primary succession is a succession that involves an area where no form of life has grown previously, hence, the area of land is barren e.g bare rock. Primary succession is first colonized by species called PIONEER SPECIES e.g. lichens, mosses etc.
According to this question, "the appearance of lichens and mosses (pioneer species) in an area where a glacier has recently melted away" is an example of PRIMARY SUCCESSION.
