Answer:
The cerebellum controls motor reflexes and is, therefore, involved in balance and muscle coordination. The brainstem connects and transmits signals from the brain to the spinal cord, controlling functions such as breathing, heart rate, and alertness.

Which correctly describes cytokinesis and the phase it occurs in the cell cycle?
A. It is the process in which DNA is replicated to make two copies, and it occurs in the interphase of the
cell cycle.
B. It is the process in which DNA is replicated to make two copies, and it occurs in the mitotic phase of
the cell cycle.
c. It is the process in which the cytoplasm of a cell divides to make two daughter cells, and it occurs in
the interphase of the cell cycle.
D. It is the process in which the cytoplasm of a cell divides to make two daughter cells, and it occurs in
the mitotic phase of the cell cycle.
Answer:
D
Explanation:
Cytokinesis occurs after telophase in the cycle. During cytokinesis a contractile ring forms around the cell membrane splitting the cell into two separate cells which each contain a full set of DNA
Oogenesis (a) produces diploid cells
(b) requires meiotic cell divisions
(c) produces four egg cells (d) produces
one diploid cell and three polar bodies
Can u help me only choose the correct answer pls
Answer:
Oogenesis requires meiotic cell divisions
hence correct answer is b)
In which layer of the atmosphere is most of the ultraviolet light blocked?
O A. Thermosphere
O B. Stratosphere
O C. Troposphere
O D. Mesosphere
Answer:
C. Troposphere
Explanation:
It works a lot like sunscreen, blocking out harmful ultraviolet (UV) rays from the sun. ... Most ozone is found below a 30 mile (48 km) height. ... And considering without an atmosphere we'd all die, it's kind of important to ... From the Earth's surface through the bottom layer of atmosphere, called the troposphere, temperature .
which of the following is a role of helper t cells
A( To ingest pathogens
B( to destroy cells that have been infected by viruses
C( to activate B Cells
D( to increase blood flow
According to the _______ hypothesis, the moon formed far away from the earth and was later captured by the earth's gravity.
The most popular hypothesis for the moon's origin is the _______.
Telescopes can be engineered to gather light from any portion of the _______.
In 2021 the James Webb Telescope will begin operation focusing on infrared wavelengths and must be kept extremely _______.
Scientists estimated the age of the universe to be nearly _______ billion years using Hubble's pictures and images from the Wilkinson probe.
Answer:
The correct answer is -
1. capture
2. the giant impact hypothesis
3. electromagnetic spectrum
4. cold
5. 14
Explanation:
Capture hypothesis is presented by the Urey and was dominant up to the 60s which states that the Moon was an asteroid-like wandering structure that formed somewhere far in the solar system and was captured by Earth's gravity while it was wandering.
The most dominant and popular theory for the origin of the moon is the giant impact hypothesis says that it is formed from the debris left after the collision of the earth and Theia a Mars-sized body.
Telescopes are tools engineered for collecting light from any part of the electromagnetic spectrum.
Scientists estimated that the age of the whole universe to be nearly 14 billion years with the help of Hubble's pictures and pictures from the Probe of Wilkinson
1. capture
2. giant impact hypothesis
3. electromagnetic spectrum
4. cold
5. 14
6. The moon's mass is much lower than the earth's; therefore, its gravity isn't strong enough to hold an atmosphere. This lack of an atmosphere and the moon's small size allowed it to become cool enough to the point at which it completely solidified. Thus, the moon doesn't have any plate tectonic activity.
