Answer:
Africa needs to urgently put a number of additional measures in place to speed up these advances, and to move towards eliminating the disease. These include accelerated investment and deployment of vaccines, new diagnostic tools, new funding strategies for malaria control and keeping in check the drug and insecticide resistance challenge.
Explanation:
In order to determine the percentage of kilocalories Sally obtains from carbohydrates, we require the number of kilocalories obtained from carbohydrates and the total kilocalories obtained. Then, we may use the formula:
Percentage from carbohydrates = (number from carbohydrates x 100) / total
Next, if the value obtained is between 45% and 65%, then it fits within the acceptable macronutrient distribution range.
Answer:
The nucleus houses the genetic material of the cell: DNA. DNA is normally found as a loosely contained structure called chromatin within the nucleus, where it is wound up and associated with a variety of histone proteins. When a cell is about to divide, the chromatin coils tightly and condenses to form chromosomes. hope this helped!

There are different types of fins present in different kinds of fishes. Each kind of fin is best suited to perform different actions.
Answer:
In eukaryotes, recombination during meiosis is facilitated by chromosomal crossover. The crossover process leads to offspring having different combinations of genes from those of their parents, and can occasionally produce new chimeric alleles. The shuffling of genes brought about by genetic recombination produces increased genetic variation.
