Answer:
C. Chromosomes
Explanation:
During fertilization in sexual reproduction, the nucleus of the male sperm cell fuses with the nucleus of the female egg cell. Chromosomes from the sperm combine with chromosomes from the egg to give the new cell a unique genetic make-up.
The hormones released from adrenal cortex are lipid soluble. These hormones are aldosterone (improves sodium absorption and potassium secretion in kidney), and cortisol (stimulates the breakdown of fats, improves gluconeogenesis in the liver).
Answer:
Mississippian fossils are abundant in portions of the Midwest and South and include vast beds of limestone and marble.
Explanation:
For example, the domed ceiling of the Jefferson Memorial in Washington, D.C., is made of Indiana limestone that was deposited during the Mississippian Period.By the end of the Carboniferous, reptiles had migrated well toward the interior of Pangea. These early pioneers went on to spawn the archosaurs, pelycosaurs, and therapsids of the ensuing Permian period. (It was the archosaurs that went on to spawn the first dinosaurs nearly a hundred million years later.)
Answer:
Chromosome 11 likely contains 1,300 to 1,400 genes that provide instructions for making proteins
The right option is; B) the total variety of organisms on Earth
The total variety of organisms on Earth explains biodiversity
Biodiversity is the variety and variability of all species (different plants, animals and microorganisms) from all sources (marine, terrestrial and other aquatic ecosystem) on earth or within a particular region. Biodiversity involves genetic diversity, species diversity and ecosystem diversity which all functions together to form the complexity of life on earth.
