Answer:
Because sickled cells restrict blood flow, individuals can periodically experience swelling and extreme pain in any body organ or joint. This can last for hours or weeks. Sometimes permanent damage can occur to organs deprived of oxygen and nutrients
Explanation:
Red blood cells are designed to pick up oxygen in the lungs and transport it throughout the body via the circulatory system. Their donut-like shape and water-balloon-like flexibility allows them to pass through even the tiniest blood vessels.
Sickle cell anemia is a hereditary condition that causes some red blood cells to distort into rigid crescent moon shapes.
Normal red blood cells can flow freely through blood vessels. Sickled cells get stuck in the blood vessels and cause blockages.
The 4 factors that affect the steps of the water cycle are tempersture, humidity, windspeed, and solar radiation.

The difference between animal and plant cells is that they contain different organelles, among these are the chloroplasts that plant cells contain and animal cells do not.
<h3>What are the differences between animal and plant cells?</h3>
Each of these cells will have their own requirements, which is why they will have different types of organelles to be able to meet these requirements. Among the differences will be that plant cells will have chloroplasts to be able to generate their own food since they cannot obtain it by other means, so they will manufacture sugar through sunlight.
In plant cells it will have a cell wall that will be surrounded by a cell membrane. While animal cells will not have this cell wall.
Therefore, we can confirm that plant cells and animal cells will have differences in their content, function and organelles.

Answer:
the penguins have a special care process since the hatching of the egg, the newborns receive care from their parents and have warmth from them placing themselves between their paws, the parents take turns caring for them and when the father is not with the chick, he goes in search of food, which he gives regurgitated, then the cris can go to a kindergarten where others of the same age are cared for by a herd of penguins, however his parents go to the sea and feed and continue to bring food to their son, this process it is kept until they change plumage and are ready to get their food on their own.
