Tides on Earth are influenced by
both the moon and the sun
the sun only
the moon only
neither the moon nor the sun
Answer:
The moon only
Explanation:
The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.
Which of the following changes takes place during the first trimester of a
woman's pregnancy?
О
A. The fetus begins rhythmic breathing movements.
B. The mother feels the fetus move for the first time.
C. The fetus develops hands and feet.
Ο Ο
D. The fetus develops toenails, lips, and eyelashes.
Answer:
The correct answer is - C. The fetus develops hands and feet.
Explanation:
The fetus begins rhythmic breathing during the second trimester around 26 weeks. It is controlled by the CNS system of the fetus. The mother feels the fetus move around 16 and 24 weeks of pregnancy normally around the 20th week.
The fetus develops toenails, lips, and eyelashes between the 22nd and 26th week from ectoderm. During the initial 5 to 7 weeks hands and legs are started to form as buds and then develop fully.

Which statement describes a difference between the nitrogen and carbon cycles?
The nitrogen cycle occurs entirely in the ocean.
The nitrogen cycle requires a process called nitrogen fixation that is carried out by certain bacteria.
The carbon cycle requires freezing temperatures.
The carbon cycle involves only plants.
Answer:
The nitrogen cycle requires a process called nitrogen fixation that is carried out by certain bacteria
The primary distinction between the carbon and nitrogen cycles is that the former involves recycling carbon, whilst the latter involves recycling nitrogen. There are numerous ways for both systems to recycle carbon and nitrogen. With gases, both cycles begin and end. Thus, option B is correct.
What between the nitrogen and carbon cycles?Both go through chemical changes that change the shape of the molecules they are contained in. All organisms that are living contain both nitrogen and carbon. Both entail releasing the element into the atmosphere in a molecular form. The cycles start and end as gases.
Therefore, The amount of nitrogen that can be absorbed into organic matter and then recycled rises as the flux of carbon does.Both involve releasing the element as a molecule form into the atmosphere. As gases, the cycles begin and finish.
