Answer:
D. Animal cells would not have the materials needed to produce energy in cellular respiration.
Explanation:
Answer:
1 out of 4
or
25%
Explanation:
First we draw a Punnett Square for this:
R r
R RR Rr
r Rr rr
So here we have the following genotypes possible for this cross:
RR = homozygous dominant
Rr = heterozygous dominant
rr = homozygous recessive
As you can see out of the four (4) possible outcomes, one (1) of them is rr. So the probability is 1 out of 4 chances or 25%.
Interferons
Virally infected cells produce and release small proteins called interferons, which play a role in immune protection against viruses.
<h3>What are Interferons ?</h3>
Interferons prevent replication of viruses, by directly interfering with their ability to replicate within an infected cell.
- They also act as signalling molecules that allow infected cells to warn nearby cells of a viral presence – this signal makes neighbouring cells increase the numbers of MHC class I molecules upon their surfaces
- So that T cells surveying the area can identify and eliminate the viral infection.
