Which statement best explains why herbivores are not considered parasites
Answer:
Hello There!!
Explanation:
The answer is=>Parasite means that the organism must live inside (intracellular) or on the outside body of the organism (extracellular). The herbivores do not live on the host (plants) for its survival. They just eat the plants and fruits for getting energy. Therefore, the herbivores cannot be called as parasite.

Over the past 60 years, many amphibian species have experienced significant population declines and some species have become extinct. Scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. However, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. These global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. In Switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. Some biologists urge the collection of the few remaining individuals of some of the most threatened amphibian species, to preserve them if they become extinct in the wild. If such captive breeding programs could produce thousands of individuals from just a few of the remaining survivors, the species will still be threatened because of ______.
Answer:
a bottleneck effect
Explanation:
Genetic drift refers to the change in the allele frequencies in a population due to chance (random) events. The bottleneck effect, also known as population bottleneck, can be defined as a severe case of genetic drift caused by a drastic reduction in the population size. The bottleneck effect is well known to cause the loss of important genetic variation since alleles that were present in the original population are lost, thereby limiting its genetic diversity. One of the most common causes that may lead to a population bottleneck in a natural population is environmental disasters (e.g., earthquakes, floods, etc).

The three statements which provide reasons that scientists are considering renewable sources of energy are as follows:
Most renewable resources are clean and nonpolluting.Renewable resources can be replenished.Most renewable resources are easily available in nature.Thus, the correct options are A, B, and C.
What are Renewable sources of energy?Energy sources that are renewable are defined as those that miraculously come from natural sources and are replenished or recharged more quickly than they are actually consumed.
These energy sources are based on the idea of sources which are continuously replenished more quickly. Most of the time, this energy is produced in a clean, non-polluting manner. Since renewable energy comes from natural resources, it is substantially cheaper or free to get renewable energy in nature.
Therefore, the correct options are A, B, and C.

In 2011 and 2012, scientists working on the Banana River in Florida recorded a dramatic increase in the number of manatee deaths. Over the past 50 years, this area has also seen the human population increase by more than 500,000 people. It is believed that pollution from numerous sewage tanks leaked into the water, eliminating the manatees' food source, replacing it with an alga that is toxic to the manatee. This is an example of A) a natural cycle in an ecosystem B) the effect of increased biodiversity on an ecosystem C) human actions altering ecosystems with serious consequences D) direct harvesting in an ecosystem
Answer:
C) human actions altering ecosystems with serious consequences
Explanation:
The increase in the manatee´s death during 2011-2012 might be directly related to human actions.
The increase in the number of people during the last 50 years to more than 500,000 individuals, and probably the lack of policies and regulation, lead to an enhance in water pollution by sewage tank leaks.
Pollution probably caused a gradual decrease in the manatee´s principal source of food, which also caused an increase in the toxic algae population.
Algae caused the death of manatees as a consequence of human action that altered the natural ecosystem by polluting water.
The radiometer is designed to be placed in a sunny window and as the sun's rays strike the blades, they spin. Which kind of energy powers this device?
Answer:
Solar energy.
Explanation:
Solar energy is the kind of energy that powers the devices when the solar radiations strike on the blades of the radiometer. The device has the ability to change or convert solar energy into mechanical energy. Solar radiation is a natural resource from which clean energy can be formed that can be used for different activities in our daily life. There are certain cells that are present on the body of radiometer that produces energy needed for its running.

Wolves are predators of deer. What is most likely to happen to the deer population if the wolf population increased? 0 stay the same increase decrease Obecome extinct
Since wolves are indeed the main predator of deer, if wolves were to increase in their population, the population of the deer will inevitably decrease dramatically.
Hope this helps and if it does, don't be afraid to rate my answer as well as maybe give it a "Thanks"? (Or even better a "Brainliest"). And if it’s not correct, I am sorry for wasting your time, and good luck finding the correct answer :)
If the wolf population were to increase, it is most likely that the deer population would decrease.
What is predator?A predator is an organism that hunts and consumes another (the prey). This is known as predation.
Predators, in general, share the following characteristics: They are usually larger than their prey or, like ants, overwhelm them by attacking in large numbers.
If the wolf population increases, the deer population will most likely decrease.
This is because wolves are deer predators, and an increase in the number of wolves means more deer will be hunted and killed by wolves.
The deer population is unlikely to become extinct as a result of an increase in the wolf population because other factors such as disease, habitat loss, or human hunting can also have an impact on the deer population.
Thus, the population will decrease.

A pack of Ramboulet sheep were imported from Australia to Pakistan in November. After some days, various sheep were suddenly died. Remaining of them were carefully examined by an expert veterinarian who found that sheep were extremely weak with yellowish mucus membrane. Sheep were gasping and it was examined that some of them are anxiously looking at their belly. He prescribed some emergency drugs along with fecal examination. Results showed presence of large quantity of parasite oocytes approximately ranging from 145 -155 um in length and 85-95um in width. How will you proceed with diagnosis as veterinarian? What is differential diagnosis and lifecycle of parasite?
Answer:
Through medication.
Explanation:
First I will apply medication that kills the pathogen that is present in the feces as well as good feel to maintain the health of sheep which was weak due to the pathogens. I have to apply vaccines that kills oocyst that is responsible for this infection. A differential diagnosis refers to a list of possible conditions or diseases that could be causing your symptoms. It can be obtained from your symptoms, medical history, laboratory results, and a physical examination. We can find out the disease through the symptoms that we observe from physical examination.
