Mutation creates new genetic variation in a gene pool. ... For any given gene, the chance of a mutation occurring in a given gamete is very low. Thus, mutations alone do not have much effect on allele frequencies. However, mutations provide the genetic variation needed for other forces of evolution to act.

4. Which event would be the most predictable one year in advance of the event?
Black_prince [1.1K]

Answer:

1. an eclipse of the Sun

2. state (phase) of matter

3. 5.0 g/cm3

Explanation:

1. Eclipse of the sun occurs when the planetary bodies align in such a way that causes the moon to block sunlight from reaching the Earth. The eclipse of the Sun will be the most predictable occurrence because it follows a pattern of occurrence. Eclipse of the sun occurs after a specific period of time, hence, based on this, scientists can predict that when it will occur next using its previous pattern of occurrence.

2. Considering the following groups: Group A: water, aluminum, water vapor

Group B: gasoline, ice, air

Group C: alcohol, iron, oxygen

One would realize that each constituent of each group exists in a particular state of matter. For example, in group B, gasoline is a liquid, ice is a solid while air is a gaseous mixture. Same applies for group A and C where water and alcohol are liquids, iron and aluminum are solids, while water vapor and oxygen are gases.

This shows that the STATE (PHASE) OF MATTER was the basis of classification.

garik1379 [7]

Answer:

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

  • 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.
