Primarily, it detects peptidoglycan, which is present in a thick layer in Gram-positive bacteria. ... In Gram-positive bacteria, the cell wall is thick (15-80 nanometers), and consists of several layers of peptidoglycan. They lack the outer membrane envelope found in Gram-negative bacteria.

Answer:

Because Intercalary meristems are found in the the stem part of the sugarcane in whole length.

Explanation:

  • As we have studied about meristem regions, that these are the regions found at the nodal areas which are able of cell division and growth.  Intercalary meristem are present in the nodes of sugarcane stem which lead to the rapid increase in elongation of stem.
  • Intercalary meristem are located at the base of leaves and nodes that leads to the increase in length.
  • On the tip of sugarcane, apical or tip region meristem are found. When the tip region is removed, the presence of intercalary meristems play the role by facilitating the elongation of stems in sugarcane.

Explanation:

Half of the F1 progeny are mutant. The mutation results in 3 cotyledons is dominant and the original mutant is heterozygous.

If D denotes the mutant allele and d denotes the wild type allele.

The cross is as follows:

P: D/d × d/d

F1 denotes D/d three cotyledons

d/d denote two cotyledons

Why will many species of bird migrate to warmer climate during the winter
Doss [256]
Bird migrations began with the recession of the glaciers during the ice age. You will notice a great increase in insects in the spring time and early summer.The birds moved North to take advantage of this increase in the food supply that followed the warming in the spring and early summer. Their reproductive organs temporarily developed so they could lay eggs and raise a family. Look at the early flush of Night crawlers in the moist times of the early rains. By mid summer most of the insects have matured, mated and died. Their eggs have hatched and turned to larva and moved underground until next spring. The shortening of the days causes the reproductive functions to decrease and signals the birds that the food will soon become scarce. They move back to the area that makes it the easiest to find food and avoid freezing. which of course is the warmer climates nearer the equator. Not all birds move past the Tropics at approximately 30 degrees. Some like Chickadees may move down from Mi or Mn or Canada only as far south as Indiana. Some migrations may be quite short. For example from the mountains down to the plains. They don't generally reproduce in the warmer winter climes they migrate to. In the spring time they migrate along paths of the retreating glaciers. As the climate warms away from the tropics the birds follow the emerging insects etc to the birds selected breeding grounds.with increased insects and longer days to feed the hatching's. It is necesary to understand why they move to cooler climates in the summer to under stand why they move to eh warmer ones in the fall. As the days shorten the food supply dwindles and the babies have fledged. They move to warmer climates in winter to rest and refuel for the next years migration.
