Answer:

2. It is made of sandstone which is very porous and is easily penetrated by rainwater

Explanation:

The White House is made of gray-colored sandstone that is brought from quarry in Aquia, Virginia. The north and south porticos of white house building are constructed with red Seneca sandstone brought from Maryland.  These sandstones are porous in which rainwater is easily penetrated in it that cause damage to the white house building so it is concluded that the building is made of porous sandstone.

In a particular species of frogs, black spots are a dominant trait and their absence is a recessive trait. In a population of fr
kipiarov [429]

The expression which is the correct way to calculate the frequency of the dominant allele is 134/200. Thus, the correct option is D.

<h3>What is Allelic frequency?</h3>

The allelic frequency may be defined as the sum total of all the alleles of a gene in a population. It represents the overall genetic diversity within a population.

The allelic frequency is calculated by the formula when the genotypes are given in number. It is as follows:

2 × Number of Purebred dominant + Number of heterozygous/ 2× Total number of individuals in a population.

∴ Allelic frequency of dominant allele = 2 × 50 + 34/ 2× 100 = 134/200 = 0.67.

The allelic frequency of the Dominant allele is 0.67 while the allelic frequency of the recessive allele is 0.33.

Therefore, it is well described above.

loris [4]

Answer;

The above statement is true

Explanation;

-Complement is a system of plasma proteins that can be activated directly by pathogens or indirectly by pathogen-bound antibody, leading to a cascade of reactions that occurs on the surface of pathogens and generates active components with various effector functions.

-C3b is the larger of two elements formed by the cleavage of complement component 3, and is considered an important part of the innate immune system. C3b is potent in opsonization: tagging pathogens, immune complexes (antigen-antibody), and apoptotic cells for phagocytosis.
