Answer:
Mammals, insects, fish and plants all have different systems of exchanging gas. For mammals we breathe into our lungs, for fish they use gills and insects use spiracles.

Answer: Stem cell research has the potential to treat diseases that are currently burdened with high health care costs—especially chronic conditions such as heart disease, Alzheimer's disease or diabetes, the costs of which threaten to cripple the healthcare system.
In F1 mono-hybrid cross, all of the offspring in which generation will exhibit a single trait without blending. It is one parents id homozygous for one allele, and other parents is homozygous for the allele.
Mono-hybrid cross used to identify the dominance relation between two alleles. The hybrid of two organism with homozygous genotype which result in the opposite phenotype for genetic trait.
Mendel start this with the pair of pea plant by two contrasting trait such as tall and other one is dwarf. The cross pollination with each other which resulted that all plants are tall and this is called first hybrid generation or F1 progeny.

Answer:
D. Ultraviolet rays from the sun are prevented from reaching Earth.
surface.
Explanation:
What little is known is that the Earth's magnetic field creates the so-called "magnetic shield" that provides protection against some other dangerous forms of radiation, namely cosmic rays and solar wind.
While there is no danger of losing the Earth's gravitational field, the Earth's magnetic field is declining faster than any other geophysical phenomenon. This continuous loss of the Earth's magnetic field, and the associated increase in harmful radiation, are beyond human control.
Answer:
All of the above.
Explanation:
Allosteric protein may be defined as the protein that has multiple ligand sites and binds to the site other than the active site. Allosteric protein is involved in the regulation of metabolic pathways of the body.
Allosteric protein does not follow the Michaelis-Menton kinetics. These proteins are multisubunit protein and has the different binding sites for the effector as well as substrate molecule. These proteins are present at the committing steps of the metabolic pathways.
Thus, the correct answer is option (e).
