Generally all (animal) cells have different shapes because they do different things. Each cell type has a specific role which it
has to play in order to assist the body in working efficiently and functionally. Thus their shape supports them to carry out these roles effectively. Plant cells are not necessarily square, but they due tend to have distinct edges and be somewhat rectangular. This structure is caused by the cell wall which is very rigid and therefore forces the cell to have a defined shape.
While plant and animal cells have structural similarities, they also differ in a few ways, including in shape. Plant cells tend to be rectangular and have distinct edges, while animal cells vary widely in shape and tend to have rounder, more fluid edges. Which statement BEST elaborates on the reason for this difference?
A) Animal cells have rounded edges because they contain cell walls, while rigid plant cells do not need cell walls.
B) Rectangular shapes help plants absorb sunlight during photosynthesis, and round shapes help animal cells absorb oxygen.
C) Animal cells vary in shape because they have different functions, while plant cells are rigid to help plants grow upright.
Your correct answer would be C. plant cells have mitochondria, a very important part of the cell, which means the plant cell needs structure to carry mitochondria throughout the cell to keep the flow of the process of photosynthesis, which brings energy to the plant.
<em><u>Economic growth refers to the upward trend in the economy of a country or a state. It is the increase in the country's produce, that is goods and services over a period of time.</u></em>
<em><u>Economic growth is marked by the creation of more profit for business, thus the price of stock or goods increases. As a result the rate of employment increases as the companies have more capital to invest and employ more people.</u></em>
As the rate of employment increases, the level of income also increases which means the <em><u>consumers will have more money to spend on buying more goods and services.</u></em>
These waves are of a higher frequency than surface waves. The first kind of body wave is the P wave or primary wave. This is the fastest kind of seismic wave, and, consequently, the first to 'arrive' at a seismic station. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth.
A mutation could have no effect on the organism that inherits the mutation because of the chances of the organism's parents/producers. One parent may be dominantly having the mutation while the other parent may have the mutation but does not display its effects, thus labeling this parent as a carrier of the trait/mutation. Drawing a punnet square would best be used to describe the possibilities of each offspring and how each carries or shows the mutation inherited from their parents.
A temperature of 30 and a dew point of 30 will give you a relative humidity of 100%, but a temperature of 80 and a dew point of 60 produces a relative humidity of 50%.
