The probability of having a second child presenting the desease is 25% (i think so)
During inter-phase of cell division, the genetic material is duplicated to allow for division into 2 identical daughter cells. The tumour suppressor gene checks for errors in the DNA, and if found, apoptosis (cell death) is initiated by p53 protein. The pRb (retinoblastoma) protein stops the progression of the cell cycle form G0 into S phase if the cell division is complete hence stemming unregulated cell division.
GMOs may lead to the use of different herbicides or pesticides is a true statement.
Explanation:
The GMO crops leads to growth of weeds that can resist herbicides other than for which the GMO is genetically-modified. The over-usage or over-reliance on herbicide-resistant GMO (Genetically modified organisms) crops had given way to the growth of such superweeds.
The main characteristic of these superweeds is resistance to the herbicides or the weedkillers leading to infestation of farmlands by these superweeds Hence farmers need to add different herbicides or pesticides to control the growth of superweeds.
Answer:
A polyhydroxyl alcohol is an alcohol that has two OH molecules attached. A regular alcohol has only one
Explanation:
Answer:
The correct answer is C
Explanation:
Cytotoxic cells are lymphocytes that kills or destroy cancerous cells, infected cells especially the one infected with virus, and damaged cells.
Cytotoxic cells does not secret antibodies to fight pathogens but the secret granzyme and perforin to kills infected cells.
They recognised their host cells by using their T cell receptors(TCR).
