The outer layer of the onion cell contains cellulose as compared to the skin cell, hence option B is correct.
What is cellulose?3,000 or more glucose molecules make up the complex carbohydrate or polysaccharide known as cellulose.
The most prevalent of all naturally occurring organic substances, cellulose is the fundamental structural element of plant cell walls and makes up about 33% of all vegetable matter (it makes up 90% of cotton and 50% of wood).
The majority of all naturally occurring organic materials are composed of cellulose, which makes up roughly 33%, 50%, and 90% of all vegetative plants, cotton, and wood, accordingly.
Therefore, it decides the shape of the plant and enables the plant to grow upright, cellulose gives plant cells their stiffness, hence option B is correct.

-They are formed form the wastes of animal, plants and other living organisms.
-Coal, demolites,Coral reefsetc are the examples.
-These are rich in carbon.
-They form in the area where there are low amount of oxygen exists.
Other sedimentary rocks:
-These are formed from the formation of precipitation of dissolved materials or from the mechanical weathering.
-Breccia, sandastone,shale,etc are the examples.
-These are rich in calcium.

In a swimming pool or lake, the water is a
liquid until the water temperature gets
down to 0 C or 32. F. Water in pools
stays liquid during Las Vegas winters,
with just a bit of ice forming if it gets really cold overnight. Even when it is
chilly in January and February (usually 15° C or 60° F), water stays liquid.
Then, when our area's temperature gets really hot in the summer (usually
about 40° C or 100. F), the water in the pool is still a liquid. It would have
to be 100. C or 212. F for the water in the pool to boil! Those
temperatures have never happened on Earth.
Remember, though, that water does not have to boil to turn to a gas.
Some of the water evaporates at all temperatures. Water temperature is a
measure of the average kinetic energy of its molecules. Some molecules
have more kinetic energy than others. The molecules that have enough
kinetic energy to break the bonds with other molecules can leave the
liquid and move off into the air. That is why you have to keep filling up the
swimming pool, even though it is not boiling.
Why does water stay liquid over a large range of temperatures? Hint:
Think about molecular structure.
If a warm air mass and a cold air mass come together which one goes underneath?
which best describes the concept of natural selection?
A. an organism will always mutate to survive
B. The fittest organisms are selected for
C. Nature selects the organisms with the most Mutations
D. mutations make organisms more fit
Answer:
D.
Explanation:
Natural selection is the way that organisms adapt through adaptations to better survive and pass on the special genes which enable the offspring to survive. Saying an organism will always mutate to survive is wrong, as natural selection implies that not all organisms survive. With natural selection, nothing is "selected", so B and C are not correct. However, mutations DO make organisms "more fit" to survive their environments, so D is the answer.
Answer: The fittest Organisms are selected for
