Dvinal [7]1 year ago
5 0

Answer:

A combination of polypeptides and modified sugars that enclose the entire eubacteria.

Explanation:

A component of bacterial cell walls called peptidoglycan (PGN) promotes innate immune responses. Peptidoglycan, a polymer made of sugars and amino acids, creates the cell wall of the majority of bacteria by producing a layer that resembles a mesh outside the plasma membrane. N-acetylglucosamine and N-acetylmuramic acid residues are alternated in the sugar component. forms a saccules in the cell wall of most bacteria that resembles a bag. It controls bacterial cell shape and is crucial for osmotic stability. A heteropolymer made up of glycan strands carrying small peptides is known as a peptidoglycan.

ANTONII [103]

Answer:

B and C

Explanation:

When the Amish came to their new home, they were founding a new colony. This is considered a founding effect.

Now, there is another thing to keep in mind, and that is that the Amish are very strict about their custom, for example, the idea of family and identity. This led them to form couples, only among the members who belonged to the community.

As generations go by, genealogical relationships between individuals in the population become closer. This causes some genes, by mere probability, to become fixed (i.e. they are the only ones left in the population). As a consequence of this, the frequency of rare genes increases (polydactyly). This evolutionary process is known as gene drift.

A girl of normal stature is born to two parents with achondroplasia who have very short stature, especially disproportionately s
IRINA_888 [86]

Answer:

0%

Explanation:

Achondroplasia is an autosomal dominant disorder that is expressed in both homozygous and heterozygous dominant genotypes. Since two affected parents have a normal girl child, both the parents should be heterozygous carrier for the disease.  Let's assume that the dominant allele "A" is responsible for the disease. Genotype of both the parents of the girl would be "Aa". The genotype of girl with normal stature is "aa". Genotype of her normal partner is "aa".

A cross betwee aa X aa would get all the progeny with "aa" genotype. Therefore, all of their children would have normal stature and there is 0% probability for them to have a child with achondroplasia.
