Answer:
D. Many amino acids are encoded by multiple codons. A gene mutation that encodes the same amino acid would have no observable effect on the cell or the organism
Explanation:
If gene mutation does not change code (gene still encodes for the same amino acid), the same protein with its function will be produced. This is called synonymous mutation.
Silent mutations might also occur when codon is altered to produce an amino acid with similar function as previous (e.g. leucine to isoleucine) so that the function of protein is not significantly changed.
Are you asking what proteins do ?
Answer:
This question lacks options, the options are:
A) storing energy
B) catalyzing cellular reactions
C) building tissue
D) storing genetic information
The answer is D.
Explanation:
There are four major biological molecules found in living systems. They are as follows: carbohydrate, protein, lipids and nucleic acids. The biomolecule being described in the question is a NUCLEIC ACID. Nucleic acids are complex biomolecules made up of long chains of monomeric units called NUCLEOTIDES.
Nucleic acids are two in nature; Ribonucleic acid (RNA) and Deoxyribonucleic acid (DNA). These two nucleic acids are involved in the storage of genetic information in all living organisms. They carry the inheritable genetic information of living organisms.
The right option is b. mutualism
Mutualism is a relationship
between two organisms of different species in which both organisms benefit from
the relationship. From the question given above, both the oxpeckers and the
zebras benefits from the relationship. This type of relationship describes
mutualism.
The right option is; C)Lower her sodium intake
Heart diseases are various conditions that affect the heart. Heart diseases include heart rhythm problems, blood vessel diseases, and heart defects. Sodium is an essential nutrient for the body and it plays important roles in regulating fluid balance, and nerve impulse transmission. Higher levels of sodium in the body are normally associated with heart diseases such as hypertension. The normal blood sodium range is between 135 and 145 mEq/L.
