Answer:
The frequency of bb individuals between successive generations <u>wasn't always the same because of natural selection. The capacity of reproduction decreased by a small portion.</u>
Explanation:
Natural selection is the reason why the reproduction of bb generations wasn't always the same. The randomly selection of mates to reproduce was also variable.
I believe the answer is wave summation. They result when one wave of contraction is added to another. A 2nd contraction of the muscle occurs before relaxation of the first contraction is complete. When the stimuli is not strong to enable muscle contraction, it continues to add stimuli until the muscle contracts.
The fossilized fish which is found has jaws but no true bones belonging at point B on the Cladogram. Thus, the correct option is B.
<h3>What is Cladogram?</h3>
A cladogram may be defined as a phylogenetic tree that is based on the classification of evolutionary relationships.
In the given cladogram, D is any ancestral point from which speciation occurs. Point C is a basal taxon while A and B are sister taxons.
The organisms of point B have only jaws bu,t not true bones, while the organisms at point A have both jaws and true bones.
Therefore, it is well described above.

Answer:
Explanation:
Apart from Patricia's concern for her physical appearance and the weight she knows she'll likely gain as her pregnancy progresses, the dietitian will likely advice her not to gain too much weight because apart from her "physical appearance worries", gaining excessive while pregnant can also raise one's risk for birth complications such as C-section delivery and even premature birth.
In addition, the dietitian will likely offer Patricia more guidelines or tips such as:
****Commencing pregnancy at a healthy weight ( between 25 to 35 pounds), gaining more if underweight or gaining less if obese or overweight.
****Eating moderately but often, focusing on small, frequent meals that are high in lean proteins, fruits and vegetables.
****Drinking enough water ( about ten 8-ounce glasses of water) daily as this helps to aid metabolism and digestion as well as constipation prevention while preventing dehydration.
****Learning how to combine something healthy with less healthy cravings in the event of cravings for less healthy foods
**** Taking exercises such as walking very seriously as it helps to burn a great deal of excessive calories
**** Maintaining a recommended weight region at various stages of the pregnancy which will be in the best interest of mother and child
