Khan Academy is great! Also, Alison (it's a website) has some free courses as well.
Explanation:
Cancer occurs in dividing cells only because genetic materials divide into two equal portions during division. This process may be interrupted by carcinogenes or mutagenes to make mutate cells and then render them as cancer cells. In the brain, the cells are differentiated and there is no chance to start division, then how can cancer be found in the brain.
Answer:
Fomepizole with ethanol
Explanation:
The antidote for ethylene glycol poisioning is the administration of fomepizole with ethanol.
Ethylene glycol (antifreeze) is a poisonous, colorless and sweet tasting liquid which is usually used for antifreeze formulations. Drinking or liking of ethylene glycol deliberately or unintentionally can result in ethylene glycol poisoning. The poisoning can be treated by stabilizing the affected animal, followed by the administration of the antidote; fomepizole with ethanol. This is the most preferred antidote. Hemodialysis, sodium bicarbonate and magnesium may also be used to treat the affected animal.
Answer:
the answer is chloroplasts
Explanation:
Answer:
The correct answer is - 1/41,493
Explanation:
Let assume the frequency of the two possible same allele genotype (dominant and recessive) in an inbred population is p and q. Then the frequency of heterozygotes (H) is denoted as:
2pq + 2pqF. ( where F is the inbreeding coefficient).
The frequency of the two different hoozygotes in inbred population can be calculated as:
p2 + pqF and q2 + pqF. (Where p and q are the allele frequency of the dominant and recessive phenotype.
Given: Frequency of Alkaptonuria (q 2) = 1:500, 000
=> q = 1/707
p = 706/707 ( Approx values)
solution:
Inbreeding coefficient (F) = 1/64
Therefore,
Frequency of Alkaptonuria in second cousins= q 2 + pqF
= 1/500, 000 + (706/707 x 1/707) x (1/64)
= 1/500, 000 + 1/45, 248
= 1/41,493 (approx)
