The circulatory system plays a crucial role in carrying the nutrients absorbed by the digestive system to different parts of the body via the bloodstream. A malfunction in the circulatory system can interrupt the transportation of these nutrients, consequently disrupting the digestive process.
The digestive and circulatory systems are interconnected in the human body. Digestive process involves breaking down food into tiny particles that can be absorbed into the bloodstream. This occurs primarily in the small intestine, where most nutrients are absorbed from the alimentary canal into the bloodstream through the epithelial cells that make up the mucosa.
However, when the circulatory system malfunctions, it disrupts the absorption of these nutrients. The circulatory system is responsible for distributing these nutrients to the different parts of the body. If it malfunctions, nutrient distribution is affected, thereby hampering overall bodily function including the digestive process.
For instance, the circulatory system plays a crucial role in carrying the absorbed nutrients from the small intestine to different parts of the body for use. This is done via the bloodstream. Therefore, a malfunction in the circulatory system can hinder this important process and subsequently disrupt the digestive system.

B) The genome is DNA based and double stranded.
C) The genome is RNA based and single stranded.
D) The genome is RNA based and double stranded.
Answer:
A) The genome is DNA based and single stranded.
Explanation:
The reason why it is DNA based is because DNA contains thymine base (T). It is not RNA based because RNA contains uracil base (U) instead of thymine and in the given question there is not uracil mentioned.
It is single stranded because according to Chargaff's rule a double stranded nucleic acid must have the ratio of purine bases to pyrimidine ratio as 1:1.
Adenine (A) & Guanine (G) are purine bases while Thymine (T) & Cytosine (C) are pyrimidine bases so according to Chargaff's rule AG/CT = ~ 1. It means [A+G] = [C+T]
Also, A makes interaction with T while C makes interaction G. It means,
[A] = [T]
[C] = [G]
By this we can easily infer that a double stranded DNA will have as much A as much it has T & same goes with C & G.
But, in the given question, A = 33% while Thymine = 28% which are not equal so this means that this molecule is single stranded.
