Which statement is true about a species living in a homogenous environment compared to a species living in a heterogeneous environment? A species that lives in a homogeneous environment is more likely to exhibit phenotypic plasticity. The homogeneity or heterogeneity of an environment does not determine whether a species will exhibit phenotypic plasticity. Only a large population in a homogeneous habitat can exhibit phenotypic plasticity. A species that lives in a heterogeneous environment is more likely to exhibit phenotypic plasticity.
Answer:
A species that lives in a heterogeneous environment is more likely to exhibit phenotypic plasticity.
Explanation:
Phenotypic plasticity might be understood as the ability of a genotype to produce different phenotypes in response to varying environmental conditions.
Phenotypic plasticity needs epigenetic mechanisms to occur, which involve the genotype and the environment interaction to produce adapted phenotypic changes.
Epigenetic mechanisms produce changes in the expression of the genes, with no need to alter the DNI nucleotides sequences.
A heterogeneous environment imposes variability on genotypes that interact with it, producing different phenotypes. These phenotypes will vary according to environmental conditions.

If the pair of materials listed below were rubbed together, give the charge that each would have in the same order as listed. use short-form P and N. silk and paraffin wax
Answer:
Simply put, the property of electron affinity refers to the relative amount of love that a material has for electrons. If atoms of a material have a high electron affinity, then that material will have a relatively high love for electrons. This property of electron affinity will be of utmost importance as we explore one of the most common methods of charging - triboelectic charging, also known as charging by friction or rubbing.
Suppose that a rubber balloon is rubbed with a sample of animal fur. During the rubbing process, the atoms of the rubber are forced into close proximity with the atoms of the animal fur. The electron clouds of the two types of atoms are pressed together and are brought closer to the nuclei of the other atoms. The protons in the atoms of one material begin to interact with the electrons present on the other material

oxygen transport in humans involves the bonding of oxygen with
A : white blood cells
b :platelets
C :Hormones
D Hemoglobin molecules
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.

Human activities would have the least immediate impact on A. The formation of fossil fuels B. Coral bleaching C. Overpopulation D. Eutrophication
Answer:
A. The formation of fossil fuels
Explanation:
Human activities would have the least immediate impact on the formation of fossil fuels because the fossil fuels are not affected the formation of fossil fuels. The formation of fossil fuels takes millions of years because it is a very slow process. Human activities greatly affected the coral reef bleaching, over population and Eutrophication due to the release of pollutant gases in the atmosphere that greatly impact the environment.

A scientist claims that he has protected animal test subjects from a newly mutated virus using an experimental vaccine. The experimental vaccine was injected into five animal test subjects. The scientist also injected a placebo vaccine into five other animal test subjects. One month later, all of the test subjects were exposed to the mutated virus. The subjects that received the vaccination showed no sign of the disease and blood tests confirmed the presence of antibodies against the disease, but the subjects given the placebo developed symptoms of this condition. Why did one group have a placebo injected before being exposed to the virus? Choose 1 answer: Choose 1 answer: (Choice A) A They were part of the control group (Choice B) B They would be exposed to a weakened form of the virus (Choice C) C They would be protected from the disease (Choice D) D They were part of the experimental group
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.

The risk index for a tsunami occurring in indonesia is 9.7 out of a maximum of 10 how could you prevent a tsunami from being a disaster ?
Answer: Protect yourself from the earthquake or volcanic eruption when it occurs because when this happens it is very likely that a tsunami will follow. Escape from the epicenter of the disaster, get as far away as possible from the water and get to a place as high as possible.
Explanation:
Indonesia is an archipelago of almost 20 thousand islands and it is located on the Pacific "Ring of Fire" which is a region where many volcanic eruptions and earthquakes occur independently of other events in other parts of the Ring. This means, Indonesia is vulnerable to volcano eruptions and earthquakes that eventually will cause tsunamis.
A tsunami is a complex event involving a group of waves in water of high energy and variable size that occurs when a large body of water is vertically displaced by some extraordinary phenomenon, for example, an earthquake, volcanic eruption, landslides, underwater detonations, meteorite impact, glacial ice slides, and others. So it is generated by the displacement of water.
The rist index for a tsunami to occur there is 9.7 of 10, this means that such an event is highly likely to occur. Since it is a natural phenomenon, there is no way to prevent it, however, there are several actions to take into account to avoid suffering major damage when this happens. This basically consists of protecting yourself from the earthquake or volcanic eruption when it occurs because when this happens it is very likely that a tsunami will follow. So you have to take it as a warning sign to flee in time. The most important thing is to escape from the epicenter of the disaster, logically get as far away as possible from the water and get to a place as high as possible, such as a mountain. It is necessary to be aware of the news and warnings to monitor the situation.

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.
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.
