False... because they can't be transported by gravity
If you’re referring to the current Coronavirus pandemics, the reasons we want to mass vaccinate the population is to stop the spread by making it harder to find a host that it can use to replicate. The more times the RNA virus replicates, the more mutations are generated, the more likely a strain, that can escape the any immunity developed, can occur. Herd Immunity is what will help reduce the ability of a virus to spread. If the virus can’t find a host to replicate in (because the host is immune to the virus) the harder it is for the virus to spread.
Answer:
Thus, 50% of the population are are heterozygous carriers for this condition
Explanation:
Researchers have calculated that 22% of the population have Uner Tan Syndrome. This condition follows the recessive mode of inheritance.
22% have the condition = q² (genotypic frequency uu) = 22/100 = 0.22
using the formular p + q = 1, since q² = 0.22, q = √0.22 = 0.4690
Thus p = 1-q where is 0.4690 = 1-0.4690
p = 0.5310
Then p² = 0.5310² = 0.2820 = 28% (genotypic frequency of homozygous normal)
using the formula p² + 2pq + q² where 2pq is the genotypic frequency of the heterozygous carriers. Thus, we have
2 x 0.5310 x 0.4690 = 0.498 = 50%
Thus, 50% of the population are are heterozygous carriers for this condition
Answer:
Which of the following is not a way in which a vascular plant's xylem and
phloem are similar?
The function of the tissues in the plant's body
Explanation:
they perform different functions, one carries or transports water while the other transport nutrients
