The most important factor that limits the size of a cell is the ability of the cell to transport materials efficiently into and out of the cell. In this case the size of a cell should have a particular form in order to export and import material.
Answer:
<em>A line graph</em>
Explanation:
A line graph would be the best type of graph to show changes over time. A line graph constitutes of a y-axis and an X- axis. The presence of the axis will make is easier to look at the height changes which occur over time. The y-axis of such a graph could show the height, the X axis of such a graph could show the time. Hence, a line graph could be the best one to represent such a change.
A feeding adaptation an iguana has is it’s short nose. This feature is important for feeding because it helps it eat algae off rocks.
Marine and Land iguanas have similar traits even though they aren’t the same kind of iguana because, most of their predators are the same. Therefore a bird or other prey would not be able to tell the difference so that’s why land and marine would both need spines on their back.
I think the camouflage is the most beneficial in land iguanas because their predators can’t spot them that easily, and it’s a quick way to blend in. I also think that the iguanas nose on marine iguanas is the most important because when they eat algae it’s easy to eat and they don’t have to change their position when feeding.
Answer:
A change in pH will cause many cellular processes to be disrupted because they affect the biomolecules (protein and nucleic acid) responsible for these processes.
Explanation:
pH refers to the degree of acidity or alkalinity. In a cell, the structures and processes that occur in them are impossible without the biomolecules, which are carbohydrate, protein, lipids and protein.
However, unfavorable conditions like a change in pH can cause the structure of some of these biomolecules to be affected. Proteins are made up of amino acids, which gives them their shape that is peculiar to their functioning. Also, nucleic acids such as DNA are composed of nucleotides responsible for their functioning.
A change in pH will cause the bonds of the protein to be disrupted, hence altering its shape and ultimately its functioning. Likewise, the hydrogen bonds in the DNA will be broken in the presence of a high pH causing the DNA to be dysfunctional.
When these biomolecules are affected, the vital functions that they perform in a cell, which is key to the cell's survival are disrupted) are likewise affected. Therefore, the cell is affected negatively.
Answer:
look at the pictures
Explanation:
1. If we cross the parental generation which is RR x rr, the probability of the F1 generation to get rough coat is 100% and they will be a carrier of the recessive trait smooth coat.
Since the phenotypic ratio is 100% heterozygous Rr, in crossing the F1 to get the F2, we will use the genotype Rr. To get the F2, use the cross Rr x Rr.
The phenotypic ration for F2 is 3:1. There is 75% to get rough coat and 25% smooth. The answer is based on the result on the Punnett square. On the other hand, the genotypic ratio is 1:2:1. There is 25% probability to get RR genotype, 50% Rr, and 25% rr.
2. Since the two parental mice got 6 albino offspring and 5 brown mice offspring, it is approximately 50%. it takes a parental mice who is Brown that is carrying an albino trait crossed with an albino to get offspring with almost the same number. Therefore, the genotype of the brown mice is Aa.
