Answer:
- Human growth and functioning can be explained by the functioning of the cells.
- Cells are the fundamental units of humans.
- The functioning of the cells in the body determine human health.
Explanation:
The cell is the basic unit of life. Therefore the biochemical activities of the cell at a micro-level will definitely influence overall physiology at the macro level of an organism. For example, the production of Thyroid hormone at the molecular level by the cells in the thyroid glands will influence the metabolisms of all cells in a human being and therefore affect the organism’s overall growth and development.
velocity= distance / time
your distance is 180 miles
your time is 3 hours
180 divided by 3 = 60

Answer:
Most people experience increased infant mortalities at high altitudes due to the inability of the mother to provide sufficient oxygen to the developing fetus but now variation in the DNA sequence in the people that lives at higher altitudes like in Tibetans allow normal level of infant survival at high altitudes.
This variation occurred in the EPAS1 gene in the Tibetan population that is responsible for delivering oxygen more efficiently to the fetus. This nucleotide variation is also present in low landers of Beijing but natural selection selected the variant gene in Tibetan people because they require this mutated gene for their survival.
So the population passed this variant gene in next-generation, therefore, inheritance allowed the spreading of the mutated gene to the next generation therefore by natural selection and inheritance a mutated gene spread through a human population that had just begun living high in the mountains.
Answer:
The genotype of the brown parent would be heterozygous.
Explanation:
As albino is a recessive trait, both the alleles should be recessive for this trait to occur.
A punnet square is a diagram which is made to illustrate the possible genotype of the offsprings.
If the brown parent will be homozygous, then a cross with albino parent will produce offsprings with brown colour having heterozygous geneotype.
For production of albinos the brown parent should be heterozygous for the trait.
