Apa template about multiple sclerosis
garik1379 [7]

Answer:

Multiple Sclerosis is an inflammatory disease in which myelin sheath of nerve cells of brain and spinal cord are damaged.

Explanation:

Cause:- (Exact cause of inflammation is not known)

  • But damage is caused due to attack by autoimmune cells or antibodies against myelin sheath.

Types of tissues attack:-

  • Oligodendrocytes and myelin sheath is damaged and stripped away from axon and the process is known as demyelination.
  • Myelin sheaths are made up of fatty tissues and help in transmission of electric impulse.

Result of immune system attack:-

  • Damaged myelin sheath stop forming whIte matter of central nervous system.
  • Hence disrupt coordinating communication between different brain regions.

Signs and symptoms:- vary from person to person

  • Diminished eyesight.
  • Disrupt motor coordination.
  • Weak sensory perception.
  • Fatigue and dizziness.
  • Speech disorder.
  • Muscle weakness and spasticity.
  • Difficulty in urination and stool.

katen-ka-za [31]

Answer:

Dissimilar organisms might have evolved from a distant, common ancestor.

Explanation:

First of all we should know species. Species is considered as a basic unit of taxonomic classification of an organism.

Initially, the scientists are agreed on this phenomenon that all distinct species are evolved gradually from common ancestor. Today, the species which are different from each other just like hummingbirds, humans and whales are from the same ancestor but with the time passage genetic mutation occurs and at the end dissimilar organisms we can see in our environment/surroundings.

Electricity is added to recharge a battery. What is added to ADP to form ATP?
White raven [17]

Electricity is added to recharge a battery. A third phosphate group  is added to ADP to form ATP.

ATP or Adenosine triphosphate contains adenine, ribose and 3 phosphate groups.

ADP is converted to ATP by the following reaction:

ADP+Pi+energy⇄ATP

The analogy between battery and ATP can be explained as ATP is higher energy form and ADP is lower energy form like charged and uncharged form of the battery. When the terminal or third phosphate is removed from the ATP it becomes ADP and releases energy like a battery. The additional phosphate group when added to ADP forms the ATP molecule like the energy spent by the batteries are recharged by putting in additional energy. Here the additional energy is provided by the third phosphate group.
