Answer: a decrease in the growth rate
A growth rate can be defined as the rate at which the number of organisms in a population increase or decrease with respect to time. The growth rate is affected by the births, death, immigration and migration of organisms. Emigeration refers to the displacement or movement of organisms from their native place to other place in search of food, shelter, mate and due to the effect of change in season in the native land. As, a result of migration of organisms from the native land, the growth rate will decrease.
Therefore, with the increase in emigeration the growth rate will decrease.
Answer:
0% (none)
Explanation:
The female drosophila is heterozygous for X-linked recessive mutation. An X-linked recessive mutation is expressed in females only when present in the homozygous state. Therefore, the female progeny should have two copies of the mutant allele to express this mutation. Let's suppose that the genotype of the heterozygous female is X^cX and that of the male is XY. The cross would obtain progeny in following ratio=
X^cX x XY= 1/4 X^cX: 1/4 XX: 1/4 X^cY: 1/4 XY
Since none of the female progeny is homozygous recessive (X^cX^c), the cross would not obtain any female progeny expressing the X-linked recessive mutation.
Answer:
Option (4).
Explanation:
Cell communication involves various junctions like tight junctions and gap junctions. These junctions allows the communication of between cell-cell and cell-extracellular matrix connection.
The diseased animal cells activate the death cascade that may also cause death of the neighbor cells. This occur because the death molecule may pass to the neighbor cells through the gap junctions.
Thus, the correct answer is option (4).
Answer:
Yes.
Explanation:
Yes, it is good to teach the younger generation to love and appreciate nature because the nature provides everything which needed for our survival in exchange of nothing. Earth sacrifice itself for the survival of humanity which is a good example to teach our younger generation so that they also take care the nature and components of earth to prevent it from harm and degradation. Nature provides everything that maintains our survival in this world so this is our duty to take care of the nature by reducing activities that adversely affected the nature.
