what solution, (hypertonic, hypotonic, isotonic) would make osmosis go faster?
Answer:
Explanation:
Osmosis is the movement of WATER molecules across a semipermeable membrane (such as the cell membrane) from where there is a high concentration of water to where there is a low concentration of water. The interior of a living cell consists of cytoplasm, which is a solution of mostly water with dissolved substances such as salt.
Now for the fun stuff! An Isotonic solution is a solution that has the same concentration of dissolved substances as is found inside the cell. If a cell is surrounded by isotonic solution, then there is no net movement of water across the membrane by osmosis, because the concentration of water is the same on both sides of the membrane.
A hypertonic solution is a solution with a higher concentration of dissolved substances than is found inside the cell. If a cell is surrounded by hypertonic solution, then water will move OUT of the cell by osmosis because there is a higher concentration of water inside the cell compared to outside (where there is lots of dissolved salt, etc.) A cell in hypertonic solution will shrink.
A hypotonic solution is a solution with a lower concentration of dissolved substances than is found inside the cell. If a cell is surrounded by hypotonic solution, then water will move INTO the cell by osmosis because there is a higher concentration of water outside the cell compared to inside. A cell in hypotonic solution will swell up and, if there is no cell wall, may burst. A silly but simple way to remember that water moves into a cell in hypotonic solution is that "hypo causes the cell to swell up like a hippo"

Below is an image of a family tree (first generation) showing a group of mice. A dark gray mouse and a white mouse had four offspring, some had white fur, while others had dark gray fur. Use the image below to help you answer the following questions. Which of the following descriptions about the parents is most likely true?
A Their gene combinations for the fur color trait are the same.
B Their gene combinations for the fur color trait are different.
C Their gene combinations for the fur color trait depend solely on the environment.
D Their gene combinations for the fur color trait do not affect their offspring.
Answer:
I believe the answer is B.
When a dark blue fish and a light blue fish with dark blue fins were mated , all offspring became dark blue. What could also be seen was that part of the offspring got light gray fins.Explain with the help of genetics why all fish turn dark blue.
Answer:
The allele for dark blue fish must be dominant and the dark blue parent fish must be homo-zygous dominant;
This would mean the dominant allele would necessarily be inherited by all offspring and since it is dominant, it would be expressed over the other allele (light blue fish)

What is the building unit that enters the plant cell organelle membranes?
A -fatty acids
b -ribose sugar
c -simple lipids
d -nucleic acids
Answer:
It's b ribosome sugar
Mark as brainliest
The building unit that enters the plant cell organelle membranes is ribose sugar. When the ribose sugar enters it has to break down into various substituents.
What is the number of carbons in ribose sugar ?The number of carbons in ribose sugar is 5. It is a pentose sugar.
Fatty acids can not pass through the cell membrane as it is very big in size and because of its very larger size it is nearly not possible to enter through the cell membrane.
Simple lipid are present in the cell membrane that is it is following the fluid mossaic model that is the two layers of lipids are present om the cell membrane where the proteins are present on the outer layer. Various types of proteins are present on the membrane.
Nucleic acid is the part of the genetic material where it is present in the DNA,RNA and various proteins.

b. Which types of reproduction are followed in sugar cane plant and in mango tree?
Sugar cane plant reproduce asexually whereas mango can reproduce by both asexually and sexually.
Sugar cane is usually reproduce by using asexual reproduction i.e. by the use of pieces of stem of sugar cane called setts that contain at least one node. It is necessary that these cuttings contain a node because when they are placed and covered in the ground, primary roots arise from these nodes.
While on the other hand, the mango trees can be propagated both by sexual and asexual reproduction. Sexual reproduction involves the fusion of male and female sex cells during flowering stage. Grafting, Cutting, Layering and Budding are the asexual means for the propagation of mango tree.
Among these the grafting technique is considered as the most suitable method of vegetative propagation of mango so we can conclude that sugar cane plant reproduce asexually whereas mango can reproduce by both asexually and sexually.

Lateral fibrous roots can extent to more than twice the spread of the canopy of the apple tree and are influenced by soil, water availability and competition from the roots of other plants.
Answer:Tap roots.
Explanation:Because the roots are long.
