Answer:
Explanation:
Bionomial nomenclature helps scientists by helping them classify organisms. This would be a two-name system that scientists use that describes the genus and species of the organism.
Answer:
Embryonic period
Explanation:
The time period of the growth of the baby in the womb of the mother of human is 38 weeks or 9 months.
The time period of 38 weeks is divided into three phases related to the events taking place in that period which are: the germinal period, embryonic period and the fetal period.
- The germinal period lasts from the implantation to the gastrula phase during which the germ layer begins to form that is in the first and second week.
- The embryonic phase begins after the second week and lasts about the eighth week which is marked by the phase of embryonic and differentiation.
Therefore, in the fifth week she is in the embryonic phase of prenatal development.
Answer:
there are many things that are not studied by biologist such as physics, figuring out new elements
Explanation:
biologists are people that study peoples life
Answer:
d. The normal bonding between the R groups has been disturbed and the protein loses its normal shape.
Explanation:
Denaturation is the loss of function of a protein due to its altered three-dimensional structure. To function properly, proteins must be present in a properly folded form. The three-dimensional structure and protein folding are mediated by weak interactions such as hydrogen bonds, electrostatic interactions, etc. An abrupt increase in temperature, pH or presence of some organic solvents causes protein denaturation.
The organic solvents target the hydrophobic interactions between the R groups of amino acids that make the core of globular protein stable. Extreme levels of pH target the net charge on proteins and thereby results in electrostatic repulsion between closely placed amino acids. Extremes of pH also disrupt the hydrogen bonding between the R groups of the amino acids. The effect is the loss of the three-dimensional structure of proteins, their partial or complete unfolding and loss of function.
Answer:
Through their lungs.
Explanation:
They need lungs to take in oxygen and oxygen is vital for survival.
