Answer:
The first blank can be correctly filled up with proteins.
Proteins are complex molecules which play many crucial roles in the body such as structural role (actin, myosin, keratin), movement, metabolism (enzymes), signal transduction, transport, and defense. In addition, they also determine many traits of the body as they are the last result of the gene expression.
The second and third blanks can be correctly filled up by DNA (deoxyribose sugar).
DNA is the genetic material in most of the organisms including humans. It contains all the information or blueprint for the synthesis of proteins which in turn help in determining the traits of a person.
The last blank can be filled up by the gene.
A gene refers to the unit of heredity which is present on the chromosome. It refers to the protein coding region of the DNA.
A decreased cardiac muscle contraction will result in a reduced cardiac output which means there will be less oxygenated blood that will circulate through the body. This will cause the supply of the energy is limited. When the demand of energy is increased, like when doing exercise or walking upstairs, the energy might be not enough. This can cause the elder to feel easily fatigue. Chest pain is also common as the heart could also not getting enough blood.
Decreased cardiac output also can cause lower blood pressure, make the elder be at risk of postural hypotension. The symptoms would be feeling dizzy if going stand right after wake up. Don't go stand after wake up. Try to sit down a moment instead so the blood pressure will not decrease too much.
Answer:
Due to the absence of proteolytic enzymes.
Explanation:
The study diagnosis that small intestine digested protein slowly due to the absence or decrease quantity of proteolytic enzymes in the small intestine. Proteolytic enzymes are responsible to speed up the digestion process and after digestion amino acid is produced which is directly injected into the blood that is used by the body for the formation of muscles.
