It results in identical offspring
It increase genetic diversity through meiosis, crossing over, and random assortment of chromosomes
Answer:
it increase the genetic diversity through meiosis , crossing over and random assortment of chromosome
Explanation:
There are two main processes during sexual reproduction: meiosis, involving the halving of the number of chromosomes, and fertilization, involving the fusion of two gametes and the restoration of the original number of chromosomes.
while asexual reproduction doesn't form any reproduction that involves neither meiosis nor fusion of gametes

Explanation:
while a neuron membrane is depolarizing its __________.
Given what we know about the depolarization of neurons, we can confirm that while a neuron membrane is depolarizing its sodium gates are fully open.
Throughout the human body, sodium is often used to cause shifts in membrane potentials, as well as a variety of other metabolic processes, due to the electric charge of this ion. One such example is the neuron, which uses a flood of sodium ions to depolarize its membrane.
During depolarization, the membrane potential changes from a negative charge to that of a positive one. This is caused by the rapid flooding of sodium into the cell, which increases the positive charge in the interior of the cell and thus affects the membrane's potential.

1. How does Air move in Earth's Atmosphere?
Answer:
Air in the atmosphere moves around the world in a pattern called global atmospheric circulation. ... When the air cools, it drops back to the ground, flows back towards the Equator, and warm again. The, now, warmed air rises again, and the pattern repeats. This pattern, known as convection, happens on a global scale.

ANSWER FOR BRAINLIEST!
Answer:
2
Explanation:
why it is important that the product of mitosis are two identical daughter cells.
Answer: Mitosis involves the division of a cell into two identical daughter cells. Each daughter cell needs a copy of every chromosome, so the process begins with cutting the chromosomes into manageable copies, so the process involves copying the chromosomes and then separating them and then so each cell has the full set. chromosomes have exactly 23 pairs of chromosomes, its hard to remember because you can also say 46 chromosomes but never say 46 pairs because doing so will result into you saying 92 chromosomes. you can either say 23 pairs or 46 chromosomes.

Which statement about the specific immune response is FALSE?
Each T or B cell has antigen receptors for only one specific antigen.
T and B cells recognize antigens by using antibodies bound to their surface membranes.
Unique antigen receptors are created by genetic recombination.
Antigens must be presented by an MHC molecule for T and B cells to recognize them.
All cells express MHC-I molecules, but only antigen-presenting cells express MHC-II molecules.

A goniometer measures __________..
Answer : A
Explanation : A joint's maximum range of motion
Hope this helps you!
Answer:
A. a joint's maximum range of motion
Explanation:
A goniometer is a device that is used to measure the maximum arc of motion made by a joint. The traditional goniometer consists of a protractor and two extending arms ,one of the arms is movable while the other one is stationary.To take measurements the center of the goniometer is aligned with the center of a joint. Then the arm of the goniometer is moved until it aligns with the limb that has been moved to a maximum position that the joint allows. The angle made between the two arms of the goniometer is measured in degrees and is the maximum range of motion of the joint.
