Answer: Option (c) is the correct answer.

Explanation:

In warm air molecules have more kinetic energy. As a result, there are more number of collisions between air molecules. Hence, it rises more rapidly.

Whereas in cold air, molecules have less kinetic energy and thus they have less number of collisions between them.

Thus, in the diagram we can see that warm air begin to rise from position marked as 3 before colliding with cold air.

Is it possible for plant breeders to develop a true-breeding pink-flowered snapdragon?
abruzzese [7]

Answer:

No.

Explanation:

Pink flower colour in snapdragon is as a result of incomplete dominance. The pink flower colour has no allele in nature. Instead, the pink colour results from incomplete dominance of the allele that codes for red flower colour over the allele that codes for the white flower colour.

Assuming that the allele for red flower colour in the plant is R and the allele for white flower colour is r, true breeding red and white flower colour plants will have the genotype RR and rr respectively. In heterozygote state (Rr), the phenotype is usually pink, showing that the R allele has incomplete dominance over the r allele.

<em>Hence, there is no way for plant breeders to develop a true-breeding pink-flowered snapdragon. without some genetic manipulations/mutation.</em>

How do you mathematically represent chromosomes?
Elodia [21]
<h2>♨ANSWER♥</h2>

<h3>↪Chromosome design</h3>

Traditionally, chromosomes are represented in binary as strings of 0s and 1s, however other encodings are also possible; almost any representation which allows the solution to be represented as a finite-length string can be used.
