O relatively large genome, dynamic cytoskeleton, compartmentalized metabolic processes
Explanation:
Eukaryotic cells also contain other membrane-bound organelles such as mitochondria and the Golgi apparatus, and in addition, some cells of plants and algae contain chloroplasts. Unlike unicellular archaea and bacteria, eukaryotes may also be multicellular and include organisms consisting of many cell types forming different kinds of tissue.
DNA is located in the nucleus, the mitochondria and the chloroplasts (occuring only in plants and some protists). The nucleus contains most DNA. It is present in this compartment in the form of linear chromosomes that together constitute the genome.
Eukaryotic cells generally use aerobic respiration – requiring oxygen – to produce usable energy called ATP from glucose molecules. ... Prokaryotic cells, on the other hand, tend to use anaerobic respiration – not requiring oxygen.
The correct answer is - Most killer whales congregate in the areas that are near the Arctic/Antarctic Circles.
The killer whales have a very large distribution, and they can be found in all oceans, apart from the Southern Ocean. It is noted though that the population density of the killer whales differs from place to place. The higher concentrations are found around the Arctic and Antarctic Circles, where there's cool rich waters, while in the lower latitudes they are much rarer. The reason for this probably lies in the fact that most of the animals that are considered to be the prime food source of the killer whales are living in this rich cold waters.
Answer is only 1st case that is homozygous zygote is the right answer.
Explanation:
In maternal recessive mutation both the alleles are mutant and exhibit mutant phenotype. The mutated alleles are present as homozygous.
From the definition it is concluded that:
first case, homozygous zygote is mutant phenotype
second case, heterozygous zygote not mutant phenotype
in third case, heterozygous zygote not mutant phenotype.
Stressors may be natural in origin, being associated with such environmental influences as:
competition, predation, disease, and other interactions among organisms
constraints related to climate or to inadequate or excessive nutrients, moisture, or space
disturbances such as wildfire and windstorms
