Answer:
D. All of the above
Explanation:
Just as when we grow and need more food and energy so does a cell. when a cell is growing there is more of it that can be utilized putting more stress on the DNA to code whatever it needs. The bigger the cell is the denser and thicker the cell membrane gets making it harder for materials to work its way in and out of the cell.
Answer:
The correct answer is - C. protein.
Explanation:
Ribosomes are biological molecules that are made up of RNA and proteins. These molecules produce protein molecules with the help of mRNA by the process of translation. These molecules are called the factory of protein or protein synthesis site.
The RNA that is present in these molecules is ribosomal RNA. These are attached to the other cell organelles called endoplasmic reticulum used the protein to check and modify them.
I believe the answer you're looking for is fertilization. :D
Answer:
A. much of the variation in individuals of a population is heritable
Explanation:
Charles Darwin is a scientist well known for his development of the concept of evolution. Darwin was able to deduce that the species of a population have a common ancestor and that as time passes there is a modification in the characteristics of these species that makes it easier for them to adapt to their environments. These traits that were inherited from past descendants, were helpful traits that made it possible for their own descendants to be able to survive better than their peers. He noted that there were limited resources for survival, therefore it was a case of the survival of the fittest.
Natural selection was the term used by him to describe how species of a population survived over time. Members of a population had varied traits that enabled them to survive. For example, the descendants of an ancestor could have slightly different shapes, colors, sizes, and other features but still maintain traceable heritable traits.
Answer:
The correct answer is option D, that is regular or uniform.
Explanation:
The individuals in a population can be spaced in a distinct manner known as the dispersion patterns. The most common arrangement is the clumped dispersion in which these individuals are clustered together. In random dispersion, the individuals are aligned randomly, and in uniform or regular dispersion, the individuals are spaced evenly.
The given case is an illustration of regular or uniform distribution. It is less common in comparison to clumped distribution. The pattern of uniform or regular distribution is witnessed in the populations of the species in which the distance between the adjacent individuals is enhanced. The requirement to enhance or increase the space between the individuals usually originates due to competition for a resource like nutrients or moisture.
