Answer:
A. The model illustrates active transport because energy is required for solute particles to cross the cell membrane.
Explanation:
Active transport is the transport of molecules from a region of lower concentration to a region of higher concentration. In other words, movement occurs against a concentration gradient.
Due to this, it requires energy in form of ATP for this movement to occur. Hence, based on this question, the model illustrates active transport because energy is required for solute particles to cross the cell membrane.
Cells get nutrients from their environment, but where do those nutrients come from? Virtually all organic material on Earth has been produced by cells that convert energy from the Sun into energy-containing macromolecules. This process, called photosynthesis, is essential to the global carbon cycle and organisms that conduct photosynthesis represent the lowest level in most food chains (Figure 1).
The question is incomplete as it does not have the option which are:
- No DNA replication would occur because DNA isn’t replicated during interphase.
-
All chromosomes would be replicated, but more slowly than usual.
-
A single chromosome would be replicated.
-
No DNA replication would occur because multiple origins of replication must interact to replicate DNA.
Answer:
All chromosomes would be replicated, but more slowly than usual.
Explanation:
Origin of replication refers to the sequence of the DNA in the genome of the organism where the process of replication begins.
The opening of the origin of replication allows the binding of the replisome complex at the terminals which initiates the process of the replication.
The number of origin of replication varies in the prokaryotes and the eukaryotes as the prokaryotes possess only one chromosome which requires only one origin of replication but eukaryotic chromosomes are large which contains multiple of origin of replication.
In the given condition if the chromosome contains only one origin of replication then the replication process will get slower as the large size of the eukaryotes will have to be replicated by only one Ori sequence.
Thus, the selected option is the correct answer.

Answer:
A completed Punnett square shows all of the following except "the actual results of a genetic cross"
Explanation:
As we know, that genetic crossing is the determined breeding of the two specific individuals which results in the mixing of the genetic materials that are visible in the offspring. These crosses can be done in the different models like plants, yeasts, flies and also in the mice. These organisms are mostly used for the dissection to know the genetic processes or can be used for creating some novel characteristics. They are mostly two types i.e. monohybrid and dihybrid cross.
