Answer:

the correct option is A "peptides form crosslinks between polysaccharides"

Explanation:

The bacterial wall of bacteria is made up of a complex peptide that is called peptidoglycan, which in turn is intertwined with polysaccharides and many more structures such as protein, this wall is confined or has the function of being able to protect the osmotic balance of the bacteria so that it does not go into failure and does not lose vitality. If the wall breaks, the bacteria goes into osmotic shock and dies, which is why this was a great discovery, because although it is very difficult to pass through antibiotics or antiseptics, once the porification of this wall is generated, the osmotic balance is lost and bactericidal power is acquired.

In garden peas, tallness (T) is dominant to shortness (t) and axial flowers (A) are dominant to terminal flowers (a). What are t
Delicious77 [7]

Answer:

The correct answer is explained below:

Explanation:

  • According to the question, heterozygous tall, heterozygous axillary plant has the following genotype, TtAa.
  • It produces the following gametes: TA, Ta, tA, ta.
  • The heterozygous tall, terminal plant has the following genotype: Ttaa
  • It produces the following gametes: Ta, ta.
  • Crossing them,

           TA                       Ta                     tA                        ta

Ta      TTAa                   TTaa                 TtAa                   Ttaa

     (Tall, Axillary)    (Tall, Terminal)    (Tall, Axillary)    (Tall, Terminal)

ta       TtAa                    Ttaa                  ttAa                   ttaa

     (Tall, Axillary)     (Tall, Terminal)   (Short, Axillary)  (Short, Terminal)

  • The genotypes of the offspring obtained are: TTAa, TTaa, TtAa, Ttaa, ttAa and ttaa respectively.
  • The phenotypes obtained are:
  1. Tall, Axillary = 3.
  2. Tall, Terminal = 3.
  3. Short, Axillary = 1.
  4. Short, Terminal = 1.

Alexxx [7]

Answer:

Well...

Explanation:First of all skin color is determined by how much melanin you have and the one thing that would show more variability in the human population is probably the one that uses less genes, because of how we come from only two genes which makes us different.
