The monarch butterfly can be found in a wide range of areas across Canada and the northern United States during the spring and
hichkok12 [17]

In order to survive the winter, monarch butterflies "migrate to warmer areas".

<u>Option: B</u>

<u>Explanation:</u>

  • The survival for Monarch butterflies is not possible in any of the United States 'cold winters, therefore they are needed to migrate south and west every autumn to avoid the cold temperatures.
  • This species migration usually begins around every year in October, but may begin quicker if the weather turns cold earlier than that.
  • Thus they spend their winter hibernation all year round in Mexico and some areas of Southern California where the temperature is warmer.
  • If the monarch stays in the Eastern states, typically east of the Rocky Mountains, then they will migrate to Mexico and hibernate in <em>oyamel fir</em> trees.

Animal regeneration can produce whole organism or parts of organism and repair injury.

Clones today are done at genetic level by using molecular biology techniques as compared to old days when only nucleus would be removed from the egg cell and desired nucleus is inserted for cloning.

Explanation:

Regeneration is a process in which whole organism or part of which is produced from pre existing cells or group of cells and tissue. Regeneration helps in maintaining the integrity of morphology and physiology.

In lower animals like hydra and planaria whole organism is generated by existing parts. This process is termed as totipotency.

In higher animals however injury repair by mitosis is an example of regeneration.

Plant structure involved in vegetative propagation are: bulbs, rhizomes and tubers.

Vegetative propagation can be done by grafting, cutting, bulb formation, tuber, layering and tissue culture methods.

Cloning is a process in which a genetical or identical copy of an organism or the cell is made by molecular biology techniques. The use of DNA sequences, molecular scissors, stem cells and plasmid are the latest techniques of cloning.

Cloning is used for treating serious diseases as diabetes and heart injury.

In old days one cell would have its nucleus removed and placed into the egg and eventually organism produced

Advantages of tissue culture:

From a single explants, large number of plants can be made.

Obtaining plants of desired trait from tissue culture is easy in short span.

No seeds are required for the growing of new plants.
