Answer:

When a gene mutation occurs, the nucleotides are in the wrong order which means the coded instructions are wrong and faulty proteins are made or control switches are changed. The body can't function as it should. Mutations can be inherited from one or both parents. They are present in the egg and/ or sperm cells.

What type of mutation can affect offspring?

The only mutations that matter to large-scale evolution are those that can be passed on to offspring. These occur in reproductive cells like eggs and sperm and are called germ line mutations. No change occurs in phenotype. Some mutations don't have any noticeable effect on the phenotype of an organism.

Explanation:

Genetic alternations include chromosomal abnormalities and gene mutations. Chromosomal abnormalities generally arise during cell division. ... Gene mutations are permanent changes in DNA gene sequence. They can arise during normal DNA replication or in response to environmental factors.

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.

Oksana_A [137]

Answer:

D. Changes in the environment changed each morph's ability to evade predation in different ways.

Explanation:

The moth species<em> Biston betularia</em> has two color morphs, or variants. One has a speckled white and black color, while the other is all black. Over the period of time, the distribution of moths dramatically changed between 1900 and 1950 in such a way that black morph became dominant but speckled morphs became very much declined in abundance. The reasons behind this change was heavy industrial pollution in UK between 1900 and 1950.

When the environment became very polluted, dark and blackish, the speckled moth had more chanced of getting eaten by predators thats why they declined in number  as compared to black morphs. On the other hand, backgrounds of grime and soot made black morphs less visible to the predators and they survived well. This is an excellent example of natural selection that only those specie better survive that have the ability to cope better with adverse environmental fluctuations.

Therefore, option D is best option.

Hope it help!
