Is the following cell a plant of an animal cell? How do you know? Plant cell because there is a cell wall and a chloroplast O Plant cell because there is a large vacuole and a cell wall 0 Animal cell because there is a cell membrane and no chloroplasts O Animal cell because it has a cell wall and a a large vacuole
Answer:
A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane.

Determine the proper number of chromosomes that would be found in a human cell at each stage of the cell cycle.
Answer: The genetic material of the cell is duplicated during S phase of interphase just as it was with mitosis resulting in 46 chromosomes and 92 chromatids during Prophase I and Metaphase I. However, these chromosomes are not arranged in the same way as they were during mitosis.

what is the definition of natrual asexul reprduction?
Answer:
In natural asexual reproduction, roots can give rise to new plants, or plants can propagate using budding or cutting. In grafting, part of a plant is attached to the root system of another plant; the two unite to form a new plant containing the roots of one and the stem and leaf structure of the other.

which instrument would produce
sound with the longest wavelength?
a. Flute
b. Bass guitar
C. Violin
d. cymbal
Answer: Long wavelengths are the result of a deeper sound since it takes longer for it to travel through a medium. The Bass Guitar is your best bet as it is the lowest sounding instrument, meaning is had the longest wavelength.

Explanation:
When the environment acts for or against one extreme characteristic, this is an
example of which category of natural selection?
Answer:
Directional selection
Explanation:

2. A
Explanation:
how to do this question plz
Answer:
We are only given one leaf, but the leaves in layer D of the same species would not be identical. Some of them could have deeper indentations or fewer indentations. A wider leaf surface area lets a plant absorb more sunlight, so it would be an advantage if leaves have fewer indentations.
The plants with fewer indentations will reproduce more, passing on their genes for fewer indentations. This repeats for a long time, then plant leaves overall would only have very small indentations (like the leaf for layer B).
Explanation:
There are mutations and variations that make one organism different from another organism, even if they're the same species.
Natural selection is when the environment "chooses" the organisms that have an advantage in the environment to reproduce. Organisms that are selected to reproduce can pass on their genes to future generations.
The deep indentation leaves from layer D were basically "phased out".
Edrophonium is a drug the blocks cholinesterase from breaking down acetylcholine in the muscles. Why does this improve Annie's muscle function?
Answer:
Edrophonium is a drug used for the treatment of myasthenia gravis, a long-term neuromuscular disease that leads to varying degrees of skeletal muscle weakness, which results from antibodies that block or destroy nicotinic receptors at the junction between the nerve and muscle. By blocking cholinesterase, an enzyme which demolish acetylcholine, it increases the amount of acetylcholine in the neuromuscular junction improving the muscle weakness
It improves Annie's muscle function as a result of the acetylcholine not
being able to be broken down in the muscles.
Acetylcholine is a neurotransmitter that sends signals to the brain and other
parts of the body in the activation of the skeletal muscles.
The drug known as Edrophonium which blocks cholinesterase breaking
down acetylcholine in the muscles will thereby lead to more presence of
acetylcholine and a corresponding increase in the muscle functions.
