The parental phenotype is the mother's free earlobes (Ff) and the father's nonfree earlobes (ff).
<h3>What genotype and phenotype?</h3>
The genotype refers to the information present in an individual's genome. Unlike the phenotype, it is not observable and rarely changes. The phenotype, in turn, depends on a combination between our genotype and the environment and can be defined as the observable characteristics of an individual.
With this information, we can conclude that the parental phenotype is the mother's free earlobes (Ff) and the father's nonfree earlobes (ff).

Ans 2. On a human body, dorsal refers to the back portion of the body.
Ans 3. On a human body, ventral refers to the front part of the body.
Ans 4. Anterior is the front of a structure, or a structure found toward the front of the body.
Ans 5. Situated at or toward the hind part of the body.
Ans 6. the upper part of the human body, or the front or upper part of the body of an animal, typically separated from the rest of the body by a neck, and containing the brain, mouth, and sense organs.
Ans 7.It separates the outer ear from the middle ear. When sound waves reach the tympanic membrane they cause it to vibrate. The vibrations are then transferred to the tiny bones in the middle ear. The middle ear bones then transfer the vibrating signals to the inner ear.
<h2>(A) is the correct option </h2>
Explanation:
- Hydrothermal vents, also known as deep sea vents are the aftermath of a volcanic eruption due to shifting of the plates that form the Earth’s crust
- Black smokers are formed due to the high pressure at this depth and temperature of the trapped water because of which there is low oxygen content of water
- The black smokers emit fluids and causing it to emit chemicals such as sulfide, iron, copper and zinc
- Barophiles are organisms whose survival and reproduction is optimized to high pressures, such as those in deep sea environments
- Psychrophiles are microorganisms that can grow at 0 °C and below, have an optimum growth temperature close to 15 °C, and usually do not survive at temperatures above 20 °C
- They are found in permanently cold environments such as the deep waters of the oceans and because they are active at low temperature, psychrophiles are important decomposers in cold climates
Answer: Arginine is an amino acid that is incorporated into proteins. So if cells can not make or obtain arginine, the cell can not make proteins needed for survival.
Explanation:
Arginine is an amino acid used to build proteins, and it is classified as a semiessential or conditionally essential amino acid.
Proteins are large molecules consisting of long chains of amino acids. They perform many functions such as catalysing metabolic reactions, providing structure to cells and organisms, and transporting molecules, among many others.
Most notably, arginine is part of proteins that play an important role in many different processes such as cell division, immune function, wound healing and the release of hormones. <u>Without this amino acid, the cell cannot manufacture the proteins necessary for proper functioning</u>. So the cell dies because it cannot function properly.
Answer:
The options
A. Methylation
B. Dephosphorylation
C. Phosphorylation
D. Enzymatic transformation
The CORRECT ANSWER IS B.
B. Dephosphorylation
Explanation:
The regulation of the phosphorylation of myosin light chain (MLC) is a major step in the regulation of smooth muscle cell contraction.
The dephosphorylation of myosin light chain (MLC) occurs in smooth muscle tissue and causes the relaxation phase of the muscle cells. This step is controlled by the MLC phosphatase (MLCP).
