a predator population suddenly decreases even though the prey population stays the same. Besides disease, what could explain this change?
Answer:
hunting, the predator is in the middle of the food chain
Explanation:
hunting can WIPE OUT species as shown by the dodo bird in the past.
food chains often work as 1-2-3 or 1-2-3-4 in levels.
A predator population suddenly decreases even though the prey population stays the same. Besides disease, hunting, the predator is in the middle of the food chain.
What happens if in a particular food web a new prey animals are introduced?If in a particular food web a new prey animals are introduced, that will most likely result in the increase of the populations of the predators in that food web. The reason why the populations of the predators would increase is that there will be more pray to hunt, and more food means that the predators can increase in numbers and not suffer from food shortage.
Still, while this the most likely scenario, it has to be taken with a little bit of reserve, as it also depends on what kind of prey animal would be introduced in the food web, and what kind of predators are there in the food web. The predators in that food web are small to medium sized predators like the serval, honey badger, than there will be no increase in the predator populations as they will not be able to hunt the introduced pray animal.
Therefore, A predator population suddenly decreases even though the prey population stays the same. Besides disease, hunting, the predator is in the middle of the food chain.

Describe how the regeneration of the anole's tail showed both cell division and cell differentiation.
Please help need answers quick!!!
Answer:
In adult organisms the regenerative capacity of certain organs or tissues can be limited, resulting in an important clinical challenge for physicians and scientists [1-3].
Regeneration involves the capacity for renewal or recomposition of tissues, organs or even organisms, after considerable physical injury or damage, resulting from pathologies, tumors, congenital diseases or traumas, for example. As a consequence of tissue regeneration, both the composition and the tissue properties are restored, and the newly formed tissue is highly similar to the original tissue. The regenerative capacity is directly related to the presence of stem cells or progenitor cells, which are capable of proliferation and differentiation [4,5]. Tissues that maintain a high proliferative capacity, such as the hematopoietic system, have regenerative capacity even in adult organisms [6].
Cell proliferation occurs in repair processes in general, accompanied by intense production of extracellular matrix, with large amounts of collagen, resulting in the formation of fibrous tissue to occupy the injured area. Although there is lesion filling, both the composition and the tissue properties are different from the original tissue, and the tissue organization pattern is not restored, leading to an altered performance of its functions [2]. Skin healing processes with the presence of scars are examples of tissue repair [3].
Besides the natural processes of regeneration and repair, it is possible, through medical intervention, to fill lesions with natural or synthetic materials, aiming at the recovery of the compromised area, and conferring certain properties to the tissue, avoiding, for example, exacerbation of the initial lesion or the evolution of degenerative processes [1,7].
The three approaches can be used in tissue engineering, targeting regenerative medicine, as they allow the recovery of compromised areas in different degrees. However, the primary objective is regeneration, recomposition of the original tissue and resumption of the biomechanical and molecular properties, with the normal performance of their functions [1,7-8].
Tissue regeneration involves cell recruitment, growth, proliferation and differentiation, with the latter representing a crucial stage for the success of regeneration, avoiding the formation of fibrous tissue characteristic of the repair [9-12]. Tissues with greater regenerative capacity, such as the skin and liver, intrinsically present cells able to migrate to occupy the affected region, and the same cells maintain the proliferative capacity, enabling occupation of the lesion [3]. In other tissues the regenerative capacity is even more impaired. In the cartilage, for example, the cells remain embedded in the extracellular matrix, and the absence of blood vessels inhibits the presence of other types of component cell in the tissue; even the cell migration and proliferation processes are compromised. In general, regeneration and repair processes do not occur naturally in these cases, requiring surgical intervention to stimulate the subchondral bone marrow, thus enabling the presence of cells capable of tissue repair in the compromised area [13]. Other scientific techniques and methodologies seek alternatives to enable the processes both of repair and of tissue regeneration [9-12,14-16].
Anyhow the final stage of the abovementioned processes, cell differentiation, is critical. An understanding of the mechanisms that lead to the differentiation process in adult organisms allows the proposition of improvements in existing technologies and of alternatives geared towards the optimization of guided tissue regeneration processes, in regenerative medicine.

Cancer is a disease caused by mutations. Yet in most instances, if a parent tragically dies from cancer, this does not put their child at a greater risk than a person who parents don't develop cancer. How can cancer be caused by mutations and ot be heritable?
a. most cancers arise from mutation in germ line cells
b. mutations that cause cancer occur on specific cells, such as sex cells
c. mutations caused by environmental agents, such as tobacco smoke, occur in somatic cells
d. mutations that cause cancer are specific and cannot be passed on regardless of the type of cell they occur in
Answer:
c. mutations caused by environmental agents, such as tobacco smoke, occur in somatic cells
Explanation:
just because you're parents smoked and got lung cancer doesn't mean you'll get lung cancer. (unless you're breathing the smoke, but that's different from inheriting it.)

State two differences between respiration and breathing
Answer:
1. Respiration results in the production of energy and Breathing doesn’t provide energy.
2. Breathing is a biophysical process that involves the exchange of gases through inhalation and exhalation while respiration is a biochemical process to release energy from organic compounds which are then used for performing different physical activities.

When is the possibility of solar weather affecting terrestrial weather the highest?
A. during solar minimum
B. during the solar cycle
C. during solar maximum
D. during Total Solar Irradiance
Solar maximum is the peak when the sun's activity and its effect on terrestrial weather will be maximum. Thus, option C is correct.
What is solar maximum?Solar maximum is referred as the highest activity exhibited by the sun during its solar cycle of eleven years.
Solar maximum is an outcome of sun's magnetic poles that produces greater solar eruptions. The large number of sun spots are found as a result.
These sun spots are rich in energy and thus contributes to greater activity of the sun.
Higher the activity of the sun, higher will be its effect on terrestrial weather as sun is the main source of energy for terrestrial life.
Opposite to solar maximum is solar minimum when the activity of the sun is lowered due to reduced sun spots.
Sun storms are the example of solar maximum.
Thus, solar maximum and solar minimum are the important part of solar cycle.
