Which of the following properties of carbon give it particular importance to life
olga55 [171]

I wrote a paragraph summing the importance of Carbon a while back, see if it helps find your answer. :)

Carbon is an element on the periodic table with the symbol C, and the atomic number 6. There are many reasons that carbon is vital to life on earth, not only to humans but to plants as well. First of all, humans are made of eighteen percent carbon. It is not only found in humans, it is also found in every organism currently known, including plants in a technological way. To plants, carbon flows inside of their cells. They need it to create glucose which then works as food. To humans, it's used in many science sets. It is used in a vast array of compounds including gasoline. Gasoline is what keeps motors around the world running, and it's made up of hydrocarbons with at least 5 carbon atoms each. It also aids the greenhouse effect, keeping the earth warm and habitable by human beings.

The frequency of carriers for a rare autosomal recessive genetic condition is 0.04 in a population. Assuming this population is
sertanlavr [38]

Answer:

E

Explanation:

Hardy-Weinberg principle states that frequency of alelle and genotype will remain constant in the absence of genetic disturbances such as mutation, no change in the DNA sequence, the population must be large and others

the principle is defined by the equation

p² + 2pq + q² = 1

where the frequency of the dominant allele is p, and the frequency of the recessive allele is q. Going by the what is given which is for the carriers is 0.04 = 2pq

substitute the value into the expression

p² + 0.04  +  q² = 1;  The information is not enough to calculate either p or q going by the equation generated.
