Answer:
the correct answer is d i took the test.
Explanation:
Pls help me will give points
Answer:
D
Explanation:
D is my best bet because most have cilia and flagella to help move them around their environment.
A is for multicellular organisms, B occurs only in some unicellular but not all, C is for multicellular mostly (some unicellular can have it), but D applies to majority of unicellular (almost all have some sort of mechanism for movement)

How do electronegativity, polarity, and ph all relate and effect each other? I know moderators, you will be reported if you give a link or wasteful answer.
Answer:Electrons in a polar covalent bond are shifted toward the more electronegative atom; thus, the more electronegative atom is the one with the partial negative charge. The greater the difference in electronegativity, the more polarized the electron distribution and the larger the partial charges of the atoms.

Which action is most likely to make the team on the left win?
A. Adding one student to the team on the right
B. Instructing both teams to pull a little less so that each side is
applying only 50 N of force
C. Adding one student to the team on the left
D. Instructing both teams to pull harder so that each side is applying
150 N of force
Answer: C) adding a person on the left
This additional person will pull more force to the left side and help that team win the tug-of-war.
Choice A is the complete opposite of what we want, since it helps the red team win. Choices B and D won't change the current state because the same thing is happening to both sides. So we can rule out choices A, B and D.

Item 5 What is the role of a generator in producing electricity? The generator stores electrical energy for later use in homes and businesses. The generator spins the turbine to create mechanical energy. The generator transforms the mechanical energy of the turbine into electrical energy. The generator reverses the turbine to create electrical energy.
Answer:
The generator transforms the mechanical energy of the turbine into electrical energy
Explanation:
Electricity generator is a device that is used in generating power supply which can be used in industries, homes and for commercial and private purposes.
It operates by converting mechanical energy into electrical energy for the use in an external circuit. mechanical energy can be obtained from steam turbines, internal combusting energy, gas and water turbines and it can be obtained through the rotating shaft.
The capacity of each generator determines the amount of energy it can supply to a given place.
