Answer:
Explanation:
Sickle cell disease (SCD) is a group of inherited red blood cell disorders. If you have SCD, there is a problem with your hemoglobin. Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. With SCD, the hemoglobin forms into stiff rods within the red blood cells. This changes the shape of the red blood cells. The cells are supposed to be disc-shaped, but this changes them into a crescent, or sickle, shape.
The sickle-shaped cells are not flexible and cannot change shape easily. Many of them burst apart as they move through your blood vessels. The sickle cells usually only last 10 to 20 days, instead of the normal 90 to 120 days. Your body may have trouble making enough new cells to replace the ones that you lost. Because of this, you may not have enough red blood cells. This is a condition called anemia, and it can make you feel tired.
The sickle-shaped cells can also stick to vessel walls, causing a blockage that slows or stops the flow of blood. When this happens, oxygen can't reach nearby tissues. The lack of oxygen can cause attacks of sudden, severe pain, called pain crises. These attacks can occur without warning. If you get one, you might need to go to the hospital for treatment.
Possibly try anemia Many other acute infections, either viral or bacterial can cause anemia
Answer:
Kilo calories
Explanation:
Kilo calories is a higher unit of energy measurement as compared to the kilo joules.
In one kilo calorie there are times kilo joules.
Mathematically, it can be written as
KCal Kilo joules
Kilo joules is equal to
kilo calories
Total energy consumed by body is equal to Kilo joules
Thus energy consumed in kilo calories is equal to
Kilo calories
An example of osmosis is when the water leaves the tubules of the kidney in response to the hypertonic fluid surrounding the tubules. Osmosis in the kidneys is a filtration. Osmosis will filter the water molecules and solutes in the kidneys from the plasma to the tubule. The other choices given are not an example of osmosis. The correct answer to this question is A.
Answer:
The answer is c)soil characteristics temperature and rainfall
Explanation:
Among the physical factors are the elements corresponding to the climate, such as temperature, rainfall, soil composition and water composition, altitude, latitude, etc., these factors are known as abiotic factors. Without these factors, there would be no life. If these factors are optimal for a living being, it develops fully. However, if the opposite happens, harmful effects appear in your life.
