Answer:
Its a semipermaeble mambrane
Explanation:
Semipermeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by diffusion.
Why do you think that Darwin's principle of natural selection was important and how did it relate to future ideas of biological evolution.
Explanation:
everything can be found in the picture
Through this process of natural selection, favorable traits are transmitted through generations.
Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.What is speciation?Speciation, the formation of new and distinct species in the course of evolution. The species evolve by genetic modification.To know more about evolution here

What are some benefits of social behavior?
Answer:
Social behavior is defined as interactions among individuals, normally within the same species, that are usually beneficial to one or more of the individuals. It is believed that social behavior evolved because it was beneficial to those who engaged in it, which means that these individuals were more likely to survive and reproduce. Social behavior serves many purposes and is exhibited by an extraordinary wide variety of animals, including invertebrates, fish, birds, and mammals.
Social behavior seems to provide many benefits to those who practice it. Studies have shown that many animals are more successful in finding food if they search as a group. This is especially true if food resources are clumped together only in certain places. If more individuals are cooperating in the search, there is a greater chance one of them will find the clump of food. In some cases, foraging in a group makes it easier to capture a prey. Dolphins are known to surround a school of fish and to take turns darting into the center to eat the fish that are trapped in the middle. Many carnivores will band together when they try to capture large prey. Some examples are that wolves will hunt together when hunting moose, and lions will hunt together when hunting large prey such as wildebeests. When these animals are hunting much smaller prey, they will often hunt singly.
Many animals live in social groups partly for protection. Although one baboon might not be able to fight off a leopard, a troop of baboons often is able to do so. In addition, with more individuals cooperating together, some can serve as sentries looking for danger while the other group members are eating or sleeping. Prairie dogs and large flocks of crows normally have some individuals acting as sentries, which makes it nearly impossible to sneak up on a prairie dog town or a flock of crows.
Some animals form social groups to make travel easier. Canada geese and other bird species typically fly in a V formation. Just like bicyclists who ride behind one another in order to reduce wind resistance, the geese fly in formation to reduce the wind they must encounter. In this situation, the lead bird has the most tiring job, which is why several birds usually take turns leading the V. Some animals congregate in close proximity to one another in cold weather in an effort to stay warm. Small birds are sometimes known to huddle so closely they form a single large ball of birds.
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.

What is the path blood takes through the heart, body and lungs.
Answer:
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.
Explanation:
Answer:
1) body –> 2) inferior/superior vena cava –> 3) right atrium –> 4) tricuspid valve –> 5) right ventricle –> 6) pulmonary arteries –> 7) lungs –> 8) pulmonary veins –> 9) left atrium –> 10) mitral or bicuspid valve –> 11) left ventricle –> 12) aortic valve –> 13) aorta –> 14) body.

Complete the following table on the different types of microscopes.
Answer:
A compound light microscope is a microscope with more than one lens and its own light source. In this type of microscope, there are ocular lenses in the binocular eyepieces and objective lenses in a rotating nosepiece closer to the specimen.
The scanning electron microscope (SEM) produces images by scanning the sample with a high-energy beam of electrons. As the electrons interact with the sample, they produce secondary electrons, backscattered electrons, and characteristic X-rays.

“Dear Basketball" by Kobe Bryant Analysis

Kobe says that basketball "asked for his hustle", but he "gave his heart because it came with so much
more". What could his heart give to the game of basketball that his hustle could not?

Which is a method that scientist used to determine the composition of earths layers
Answer:
Scientists use waves to study the different layers of the earth. Usually, they use seismic waves, which are waves generated by earthquakes or nuclear-test explosions. The seismic waves are bent, sped up, or slowed down, or even reflected when they pass through the earth's layers.

Who are autotrophs ?
Answer:
autotrophs are organisms that make their own food, like plants, who make their own food through photosynthesis.
An autotroph is an organism capable of making nutritive organic molecules from inorganic materials. It could be through photosynthesis (involving light energy) or chemosynthesis (involving chemical energy).
26._____The first trophic level is usually occupied by herbivores. 27.__True___It is possible for a plant to be a carnivore. 28._____A habitat refers to the role of a species in its ecosystem. 29._____Biotic factors include sunlight, soil, temperature, and water. 30._____A food web can be represented by many interconnected food chains. 31._____There are rarely more than four trophic levels in an ecosystem. 32._____Like water, energy is also recycled through an ecosystem.
Answer:
The correct answer is -
26. false
27. true
28. false
29. false
30. true
31. true
32. false
Explanation:
The first trophic level is usually primary producers and herbivores are the primary consumers placed in the second trophic level.
There are some plants that depend on insects and small organisms for their nutrition.
Habitat is the living area of an organism it can be understood as address.
Biotic factors are the living organisms of the ecosystem while sunlight, soil, temperature are abiotic factors.
A food web is complex as it is made up of several food chains interconnected.
Normally there are only three or four trophic levels in most of the ecosystem.
Energy is not recycled in ecosystems like water or carbon.
