Natural selection is a type of selection that exists between certain inherited conditions and environmental pressures.

<h3>How does malaria and sickle cell anemia show natural selection?</h3>

The process through which populations of living things adapt and change is known as natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways. This variety indicates that some people have characteristics that are more environment-appropriate than others. Natural selection is a non-random difference in reproductive output among replicating entities.

It turns out that HbS carriers have been naturally chosen in these regions because the trait gives some malaria resistance. When they are infected with the malaria parasite, their red blood cells, which include some aberrant hemoglobin, have a propensity to sickle. The malaria life cycle intensifies both natural selection and random genetic drift.

ALL animals make use of other animals and organisms for food. They are heterotrophic so they have to get energy elsewhere.

ALL animals are capable of motion at some stage of their lives.

Animals developed specialized cells and tissues that are advanced and complex.

And because all animals eat I would assume they all digest the food they ingest. Other than parasites who don't really digest their food.

5. How can we say that added sugar is not necessary for our health (it's not), when we learned that
natita [175]

The body does not require any added sugar to stay healthy. Hunters/gatherers and our ancestors consumed fruits and milk that are natural sugar to obtain energy.

<h3>What is the difference between added sugar and natural sugar?</h3>
  • Natural sugars are found in unprocessed food such as fruits and milk.
  • Fruits contain fructose and milk contains lactose.
  • On the other hand, added sugars are the artificial sweeteners that we often add to our daily diet in the form of white sugars and caloric sweeteners.
  • From the perspective of health, it is always better to opt for natural sugar that keeps our body stable energy and stable metabolism.
  • Added sugars are harmful when consumed in higher quantities.

Hence, added sugar is not necessary for our health when we have learned that aerobic cellular respiration uses glucose as a fuel source that can be obtained from natural sugar.

A. Most people thought that trillium was not getting enough sunlight in the forest.

Explanation – Scientists used to believe that the population of trillium decreased because there were not enough sunlight to reach these plants. Later, it was found that deer used to eat the flowers of trillium plant that led to the decrease of its population.

The seed of the trillium plant is very nutritious and hence consumed by the deer. Because of this, trilliums were found to be unlikely to recolonize local areas on their own.
