Answer:
Reproductive cell cycle theory
Answer:
In the physical sciences, subatomic particles are smaller than atoms. They can be composite particles, such as the neutron and proton; or elementary particles, which according to the standard model are not made of other particles.
Explanation:
A spider plant sends out runners that have buds. When planted, the bud grows into a mature plant. The resulting plant has one parent and is <u>genetically identical</u> to the parent.
Answer: Option C
<u>Explanation:</u>
Reproduction is of two types one is sexual reproduction and asexual reproduction. The asexual reproduction mostly involves only one parent and therefore the off spring that is born is genetically identical with the parent.
whereas in sexual reproduction that involves 2 parents the off spring born contains a genetic makeup that is a combination of 2 parents and thereby not genetically identical.
Answer:
A- Acetylcholine is released by axon terminals of the motor neuron.
Explanation:
The general mechanism of muscle contraction can be explained as follows:
a) The action potential which is generated, travels along the motor nerve to its ends on muscle fiber (or motor end plate) at the neuro-muscular junction.
b) The nerve endings then secrete small amounts of neurotransmitter called acetylcholine.
c) The actylecholine binds to the receptors on the membrane of muscle fiber and opens the voltage gated sodium channels.
d) Opening of these channels leads to flow of large quantities of sodium ions into the muscle fiber which ultimately results in initiation of action potential in muscle fiber.
e) This action potential depolarizes the fiber including the T-tubules, triggering the release of calcium ions from sarcoplasmic reticulum.
f) The calcium ions thus released initiated the process of muscle contraction.
Answer:This is the exact answer so you might want to re-word it.
All the organisms an image one have a similar skeletal structure, with two legs, two arms, ribs, vertebrae, and similarly shaped skulls. However, the sizes and shapes these structures very among the species. For example, the hands of the chimpanzee, Gorilla, and orangutan are proportionally larger than the hands of the human but smaller than the hands of the gibbon.
