A variable refers to anything, which is being modified within an experiment. A dependent variable refers to the variable whose value relies on the independent variable. The independent variable refers to the variable, which is being manipulated by the experimenter.

In the given experiment, the student is experimenting that how the height from which the ball is dropped influences the bounce of the ball. The height at which the ball bounces is the variable that is being determined and relies upon the height from which the ball is dropped, that is, the independent variable.

Hence, the control variable would be the ball used.

Nady [450]
Kelp is very sensitive to temperature change. Placing the plant near the window and exposing it to direct sunlight will result in continuous warming of the water in which the kelp plant is growing. Research has shown that kelp plant degrades very quickly when temperature increases due to tissue loss.

Answer:

Symptoms

Signs and symptoms of hemophilia vary, depending on your level of clotting factors. If your clotting-factor level is mildly reduced, you may bleed only after surgery or trauma. If your deficiency is severe, you may experience spontaneous bleeding.

Signs and symptoms of spontaneous bleeding include:

  • Unexplained and excessive bleeding from cuts or injuries, or after surgery or dental work
  • Many large or deep bruises
  • Unusual bleeding after vaccinations
  • Pain, swelling or tightness in your joints
  • Blood in your urine or stool
  • Nosebleeds without a known cause
  • In infants, unexplained irritability

Bleeding into the brain

A simple bump on the head can cause bleeding into the brain for some people who have severe hemophilia. This rarely happens, but it's one of the most serious complications that can occur. Signs and symptoms include:

  • Painful, prolonged headache
  • Repeated vomiting
  • Sleepiness or lethargy
  • Double vision
  • Sudden weakness or clumsiness
  • Convulsions or seizures

Causes

When you bleed, your body normally pools blood cells together to form a clot to stop the bleeding. The clotting process is encouraged by certain blood particles. Hemophilia occurs when you have a deficiency in one of these clotting factors.

There are several types of hemophilia, and most forms are inherited. However, about 30% of people with hemophilia have no family history of the disorder. In these people, an unexpected change occurs in one of the genes associated with hemophilia.

Acquired hemophilia is a rare variety of the condition that occurs when a person's immune system attacks clotting factors in the blood. It can be associated with:

  • Pregnancy
  • Autoimmune conditions
  • Cancer
  • Multiple sclerosis

Treatment

Several different types of clotting factors are associated with different varieties of hemophilia. The main treatment for severe hemophilia involves receiving replacement of the specific clotting factor that you need through a tube placed in a vein.

This replacement therapy can be given to combat a bleeding episode that's in progress. It can also be administered on a regular schedule at home to help prevent bleeding episodes. Some people receive continuous replacement therapy.

Replacement clotting factor can be made from donated blood. Similar products, called recombinant clotting factors, are manufactured in a laboratory and aren't made from human blood.

Other therapies may include:

  • Desmopressin. In some forms of mild hemophilia, this hormone can stimulate your body to release more clotting factor. It can be injected slowly into a vein or provided as a nasal spray.
  • Clot-preserving medications. These medications help prevent clots from breaking down.
  • Fibrin sealants. These medications can be applied directly to wound sites to promote clotting and healing. Fibrin sealants are especially useful in dental therapy.
  • Physical therapy. It can ease signs and symptoms if internal bleeding has damaged your joints. If internal bleeding has caused severe damage, you may need surgery.
  • First aid for minor cuts. Using pressure and a bandage will generally take care of the bleeding. For small areas of bleeding beneath the skin, use an ice pack. Ice pops can be used to slow down minor bleeding in the mouth.
  • Vaccinations. Although blood products are screened, it's still possible for people who rely on them to contract diseases. If you have hemophilia, consider receiving immunization against hepatitis A and B

Dvinal [7]

Answer:

The correct answer will be- true and structural specializations

Explanation:

The evolution of life on earth has suggested that life has moved from the simplicity to complexity or from single-celled organism to multicellular organism.

This multi-cellularity is achieved through the property of called cellular differentiation and specialization. as the cellular complexity increases, therefore, cellular demands like the use of energy, food, water and other variables increased.

This lead to the formation of the organ and organs system specializes to perform specific functions like the digestive system and another biological system.

Thus, true and structural specializations are the correct answer.
