A. Survival of the fittest and natural selection are interchangeable terms.
Explanation:
Amylase, lipase, pepsin, trypsin
Help in digestion of food by catabolizing nutrients into monomeric units
Hemoglobin, albumin
Carry substances in the blood or lymph throughout the body
Actin, tubulin, keratin
Construct different structures, like the cytoskeleton
Insulin, thyroxine
Coordinate the activity of different body systems
Legume storage proteins, egg white (albumin) Provide nourishment in early development of the embryo and the seedling
A decreased pH coupled with a decreased plasma concentration of bicarbonate ion indicates that acidosis is occurring and the respiratory system will compensate for this change.
<span>Acidosis (metabolic) is a state when increased acidity in the blood occurs and it usually refers when arterial pH falls below 7.35. Metabolic acidosis may result from increased production of metabolic acids (lactic, for example) and is characterized by low pH, low blood HCO3, and normal or low PaCO2. Metabolic acidosis is compensated with an increased exhalation of CO2 to reduce metabolic acid.</span>
Greater genetic diversity, compared to asexual reproduction.
If you think about it, this makes sense because in asexual reproduction, an organism reproduces all by itself, and uses its own genome as the blueprint for its' offspring. However with sexual reproduction, two organisms come together, each contributing half the required chromosomes, and the offspring gets 1/2 it's genes from the mother and 1/2 it's genes from the father. Sexual reproduction allows for greater diversity because it doesn't just rely on mutations to add new diversity to the genepool.
The United Nations Conventions on the Law of the Sea (UNCLOS) declares that seabed area, which does not fall under the jurisdiction of a particular country, is a common natural heritage. The minerals of this area can be usd by anyone. Due to vast presence of sea area, and conflicting boundaries, as well as illegal mininig practices, the imposition of such laws is difficult. The very large sea areas which should not be mined, should be restrained under non mining region. But, mineral-greedy nations are not following such instructions.
The envrionmental implications of ilegal seabed mining includes, destabilisation of oceanic systems, effect on microbial systems of the sea, and danger to the creatures living in the hydrothermal vents, which are not used to light exposure.
