For Gradualism, changes in species is slow and gradual, occurring in small periodic changes in the gene pool, whereas for Punctuated Equilibrium, evolution occurs in spurts of relatively rapid change with long periods of non-change
Sally is a carrier. If a person carries the genes, but doesn't have symptoms, they are known as carriers, because they have one infective allele and one normal allele. If you're familiar with genetics, she would be a heterozygote, and the disease was a somatic autosomal disease, with one dominant, passive allele, and one recessive, infective allele.
Answer:
Genetic drift Natural
Explanation:
In evolution, which driving factor most consistently requires a small population as a precondition for its occurrence?

The methylene blue reduction test is a test commonly used to estimate the microbial load of a milk sample and as a result, examine the quality of the milk.
The principle of this test is that methylene blue is a dye which loses its colour in the absence of oxygen. Bacterial metabolism can cause the depletion of oxygen in the milk, therefore the methylene's reduction rate is connected to the presence of microorganisms in the milk.
As a consequence, if the tubes were not sealed tightly, then oxygen will enter the tube and the dye's colour will diminish, giving a false result concerning the presence of microorganisms in the sample.
Answer:
Explanation:
Hydrogen cyanide (HCN)
The molecular geometry of HCN is linear. The compound is polar in nature.
As Carbon is bonded to two atoms, it follows the molecular geometry of AX2. And as per VSEPR theory, molecules covered under AX2 have a linear molecular geometry.
Hence Hydrogen Cyanide has linear molecular geometry.
