The answer to this question would be: favorable, low<span>
Exponential growth happens when the resource is enough and competition is low. The example for this condition is when a small population move to a resourceful area. If the area having many resources, that means the area is favorable.
A low density population will need less resource. It is hard to get exponential growth in a high density population as the competition for the resource will be high.</span>
Answer: 26 stripes
Explanation:
On average, each plains zebra will have roughly 26 stripes per side. Mountain zebra - This is a threatened species, and is native to south-western Angola, Namibia, and South Africa. On average, each mountain zebra will have approximately 43 stripes per side.
Answer:
Addition of enzymes will increase the speed rate of DNA replication.
Helicase:
It is responsible for DNA strands unwinding and unzip the DNA strands from their center.
Primase:
It is responsible for 5' to 3' direction RNA primers synthesis, okazaki fragment's template.
Polymerase 3:
It synthesize the nucleotides from the 5' to 3' direction on leading end.
Polymerase 1:
It synthesize the nucleotide (okazaki fragments) on lagging strand.
Ligase:
It connects all okazaki fragments.
Topoisomerase:
Topoisomerases are used to regulate the super coiling.
Answer:
A. Heritable
C. Affected by the MC1R gene
D. Polygenic trait
Has evolved due to evolutionary processes such as natural selection.
Explanation:
Human skin color is a polygenic trait as it is regulated by more than one gene. Each allele of these genes has an additive effect on the overall skin color of an individual. Therefore, the trait is a continuous trait, not a discrete one. The genes for human skin color are transmitted from parents to progeny which in turn makes it a heritable trait.
The gene MC1R codes for melanocortin 1 receptor and thereby, regulate the skin color of humans since melanocyte-stimulating hormone binds to the receptor to trigger the synthesis of melanin from melanocytes. Evolution of various skin color in human beings is regulated by natural selection which in turn favors the skin tone best suited under the prevailing climatic conditions of a particular human population
