This image shows a Convergent boundary

Answer:

Option (C)

Explanation:

In a convergent plate motion, two tectonic plates move towards one another. Due to this type of plate motion, the denser plate subducts below the less dense plate, as a result of which a subduction zone forms and above this zone, there lies a trench. This trench is a depression that marks the boundary between the two plates. As the sinking plate melts underneath, the magma in association with the melt rises upwards, and thereby give rise to the formation of a volcano or a volcanic island. It also creates an island arc or a volcanic arc.

Thus, the correct answer is option (C).

A man who smokes heavily has developed lung cancer. The tobacco smoke has caused mutations in some of the cells in his lungs, ma
Naya [18.7K]

Answer:

The correct answer is: B. If he inherited a mutation which made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children.

Explanation:

  • The inheritance of genes from the parents to the offspring is mediated by the germinal cells or sex cells or gametes of the parents.
  • The genetic material present in the somatic cells of the parents are not transmitted to the offspring.
  • In the given case, the man who develops lung cancer generates some tobacco smoke induced mutations in some of the cells of his lungs.
  • The cells of the lungs are type up of somatic cells. Hence, any mutations in the genome of these cells will never be transmitted to the offspring.
  • Therefore, the children of the man will never become prone to develop lung cancer due to development of mutations in the lung cells of the man.
  • However, if the man has inherited any mutation from his parents which can increase the risk of development of lung cancer, then these mutations will be present in his germinal cells and also in some of his gametes.
  • Now, if a child is born due to the fusion of the the maternal gamete with one of these mutated paternal gametes, there is an increased chance of developing lung cancer in the child, irrespective of the fact whether he is a smoker or a non-smoker.

7(b). State a difference between boiling and evaporation.​
olganol [36]

Answer:

Evaporation is a regular process that occurs when the liquid form changes into the gaseous form; while causing a increase in the pressure or temperature. Boiling is an unnatural process where the liquid gets heated up and vaporized due to continuous heating of the liquid.

crustal formation,which may cause the widening of an ocean is most likely occurring at the boundary between...?
balandron [24]

Divergent boundary.

This is the boundary between two tectonic plates move away from each other in opposite directions.

Explanation:

One major example of a divergent boundary is the mid-Atlantic ridge that cuts, longitudinally, across the middle of the Atlantic ocean.

When two tectonic plates move away from each other in opposite directions, the void they leave in between is filled by rising magma from the mantle and cooling to create new crust. A mountainous ridge along a boundary is evidence of a divergent boundary. The Atlantic ocean will therefore continue to widen as the North American and Eurasian Plates move away from each other. As new crust is formed at divergent boundary, old crust is being consumed at convergent boundary on another end of earth. This way tectonic plates of earth renew themselves.

if two chromosome have equal length and size , and different in gene number would severity of chromosomal abnormalities in this
-Dominant- [34]

Answer:

Unequal.

Explanation:

The severity of chromosomal abnormalities in these two chromosome are unequal that are equal in length and size but unequal in gene number are because the gene number are different from one another. If the size of gene increase or decrease from the normal range then it will leads to chromosomal abnormalities in the cell so the cells that has normal gene number has normal chromosome as compared to those cells where abnormal gene is present so the chromosomes are abnormal.
