The three statements which provide reasons that scientists are considering renewable sources of energy are as follows:

Thus, the correct options are A, B, and C.

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.

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.

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.

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.

Answer:

A. They were part of the control group

Explanation:

In a scientific experiment, the CONTROL GROUP as opposed to the experimental group is the group that does not receive the experimental treatment. This acts as a standard for comparison.

In this question, the EXPERIMENTAL VACCINE is the experimental treatment or independent variable that was added. The five animal test subjects that was injected with this vaccine are called the EXPERIMENTAL GROUP while the other five test subjects that were rather injected with a PLACEBO are called CONTROL GROUPS.

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).

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.

Answer:

i think it's d. hemoglobin molecules

Oxygen transport in humans involves the bonding of oxygen with hemoglobin molecules. Therefore, option (D) is correct.

Human oxygen transport is essential for delivering oxygen, a key gas needed for cellular respiration, to all tissues and organs. Haemoglobin molecules in red blood cells deliver oxygen.

Oxygen diffuses into the bloodstream and meets haemoglobin in the lungs. Oxyhemoglobin is formed when haemoglobin binds to oxygen molecules. Oxygen partial pressure and other factors affect reversible binding.

The heart pumps oxygenated blood via the circulatory system to tissues and organs. Oxyhemoglobin releases its oxygen, allowing cells to use it in cellular respiration to make energy. The mechanism efficiently supplies oxygen for metabolic needs. Life and physiological activities depend on this mechanism. Therefore, option (D) is correct.

Explanation:

The pathophysiology of primary open-angle glaucoma is still largely unknown, although a joint contribution of vascular, biomechanical, and biochemical factors is widely acknowledged. Since glaucoma is a leading cause of irreversible blindness worldwide, exploring its underlying pathophysiological mechanisms is extremely important and challenging. Evidence from recent studies appears supportive of the hypothesis that a “glymphatic system” exists in the eye and optic nerve, analogous to the described “glymphatic system” in the brain. As discussed in the present paper, elucidation of a glymphatic clearance pathway in the eye could provide a new unifying hypothesis of glaucoma that can incorporate many aspects of the vascular, biomechanical, and biochemical theories of the disease. It should be stressed, however, that the few research data currently available cannot be considered as proof of the existence of an “ocular glymphatic system” and that much more studies are needed to validate this possibility. Even though nothing conclusive can yet be said, the recent reports suggesting a paravascular transport system in the eye and optic nerve are encouraging and, if confirmed, may offer new perspectives for the development of novel diagnostic and therapeutic strategies for this devastating disorder.
