Answer:
<h2>50% are brown.</h2><h2>50% are green.</h2><h2 />
Explanation:
Given;
B allele is for brown color, so B = brown,
br= red,
bg= green,
by= yellow.
B is dominant over all;
bg is dominant over by;
br is dominant over bg;
by is recessive to all other alleles.
Here, cross between brown (B/by) and pure green (bg/bg).
B/by× bg/bg
progeny
Genotype= B/bg, B/bg, by/bg and by/bg.
Phenotype= B/bg= brown;
by/bg= green
So, 1/2 are brown and 1/2 are green.
Answer to 9 is b (because bodily fluid is the easiest way to contract a disease)
And answer to 10 is a (because the disease is transferred by saliva)
<h2>Answer:</h2>
To treat the discharge of untreated waste from a type i or type ii marine sanitation device the following steps should be taken into account;
The “Y” valve must be secured to prevent accidental illegal discharge. This can be done by placing a lock or non-reusable seal on the “Y” valve or by taking the handle off the “Y” valve. Only treated sewage from an approved MSD may be discharged directly overboard.
Answer:
destruction of infected cells by cytotoxic T cells, or the destruction of intracellular pathogens by macrophage
Explanation:
A cell-mediated immune response is an immune response that does not involve antibodies. Cell-mediated immune responses involve the destruction of infected cells by cytotoxic T cells, or the destruction of pathogens by macrophages.
The answer cannot be either of the options involving B cells, as these are involved in the antibody response. The cytotoxic T cells are what actually destroy the infected cells (not helper T cells). Therefore, the answer is destruction of infected cells by cytotoxic T cells, or the destruction of intracellular pathogens by macrophage
Well if I had to guess It would be a disturbance but I do not have any answers to go of but if it is a b c or d it would be a disturbance.
