In superheroes, the ability to Fly (F) is dominant over not being able to fly (f). Superman can fly (Ff) (he has one dominant an

d one recessive trait). He marries Storm (from the X-men) who also has one dominant and one recessive trait (Ff), and can fly.

Answer:

<u></u>

  • <u>Probability that the descendents are able to fly: 3/4</u>
  • <u>Probability that the descendents are not able to fly: 1/4</u>

Explanation:

The question is incomplete.

We can build a Punnett square to find the offspring and then determine the probability that the descendents inherit the ability to fly.

  • <em>Superman's genotype: Ff</em>
  • <em>Storm's genotype: Ff</em>

Write the columns and rows titles:

           F    f  ← Superman's genes

   F

   f

   ↑

Storm's genes

Fill in the cells with the possible combinations:

           F    f

F         FF   Ff

f          Ff    ff

Homozygous FF:   1      can fly

Heterozygous Ff:  2      can fly

Homozygous ff:     1       cannot fly

                 Total:    4

  • Probabilities:

Homozygous FF:   1/4      can fly

Heterozygous Ff:  2/4      can fly

Homozygous ff:     1/4       cannot fly

                 

  • Able to fly: 1/4 + 2/4 = 3/4
  • Not able to fly: 1/4

Since the ability to fly (F) is dominant, the heterozygous Ff descendents are able to fly. That is 3/4.

Only the homozygous ff are not able to fly. That is 1/4.

As you learned in the video, non-human primates have light skin covered with fur; biologists hypothesize that the ancestors that
Andreas93 [3]

Answer:

The loss of fur is a protection mechanism for the epithelium that covers us, over the years this method of protection was replaced by the protection provided by melanocytes with their melanin, therefore people who had a low presence of melanin could not survive in the evolution.

Explanation:

The presence of melanocytes and melanin in the skin is what protects it against ultraviolet radiation, over time the human being was affected by solar radiation, thus being one of the causes of bipedalism.

In those humans where melanin is defective or a small number of melanocytes are more predisposed to suffer epithelial pathologies today.

Human evolution then led to hair loss and increased epithelial tonality, causing those who could not have this phenotypic quality to be extinct or deceased.

Streptococcus pneumoniae can escape phagocytic clearance by which mechanism
Stells [14]
<span>he Streptococcus pneumoniae capsule is vital for virulence and may inhibit complement activity and phagocytosis. However, there are only limited data on the mechanisms by which the capsule affects complement and the consequences for S. pneumoniae interactions with phagocytes. Using unencapsulated serotype 2 and 4 S. pneumoniae mutants, we have confirmed that the capsule has several effects on complement activity. The capsule impaired bacterial opsonization with C3b/iC3b by both the alternative and classical complement pathways and also inhibited conversion of C3b bound to the bacterial surface to iC3b. There was increased binding of the classical pathway mediators immunoglobulin G (IgG) and C-reactive protein (CRP) to unencapsulated S. pneumoniae, indicating that the capsule could inhibit classical pathway complement activity by masking antibody recognition of subcapsular antigens, as well as by inhibiting CRP binding. Cleavage of serum IgG by the enzyme IdeS reduced C3b/iC3b deposition on all of the strains, but there were still marked increases in C3b/iC3b deposition on unencapsulated TIGR4 and D39 strains compared to encapsulated strains, suggesting that the capsule inhibits both IgG-mediated and IgG-independent complement activity against S. pneumoniae. Unencapsulated strains were more susceptible to neutrophil phagocytosis after incubation in normal serum, normal serum treated with IdeS, complement-deficient serum, and complement-deficient serum treated with IdeS or in buffer alone, suggesting that the capsule inhibits phagocytosis mediated by FcÎł receptors, complement receptors, and nonopsonic receptors. Overall, these data show that the S. pneumoniae capsule affects multiple aspects of complement- and neutrophil-mediated immunity, resulting in a profound inhibition of opsonophagocytosis.</span>

Is osmosis and isotonic the same
belka [17]

No. Osmosis is the movement of a solvent through a membrane (semi-permeable) from a less concentrated solution to a more concentrated solution to the point where the two sides reach equilibrium. Isotonic solutions are solutions where the two sides of the membrane are already at equilibrium - so there is no movement of the solvent (like water) - so this is different from osmosis.

Why is it important for dna to be duplicated before mitosis
Ulleksa [173]
<span>If it didn't, one cell would end up with the original DNA, the other wouldn't be a functional cell, because it would lack DNA. If the DNA was split between the two cells, neither cell would have a complete copy.
