Answer:
C. Chlorophyll
Explanation:
Chlorophyll is the green pigment that absorbs the light energy for photosystems.
The substance in chloroplasts that is a green pigment and absorbs energy for photosystems is chlorophyll, which is present in Option C, as chlorophyll is the primary pigment responsible for the green color of most plants as it reflects green light,
What is chlorophyll?Chlorophyll is a type of pigment that is responsible for the green color of leaves, stems, and other plant parts, and it is found in the chloroplasts of plant cells, specifically in the thylakoid membranes, where it plays a central role in photosynthesis, and chlorophyll absorbs light energy from the sun. During photosynthesis, chlorophyll absorbs light energy and transfers it to other molecules in the photosystems, where it is used to generate ATP and NADPH, and these energy-rich molecules are then used in the light-independent reactions of photosynthesis to produce glucose and other organic compounds.
Hence, the substance in chloroplasts that is a green pigment and absorbs energy for photosystems is chlorophyll, which is present in Option C.

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).

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.

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.

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.

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.

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
