Answer: Cell division.

Explanation: Cell division is responsible for the growth of roots in the plant. The growth in the roots of the plant is ultimately the growth of the whole plant.

Roots are very important as it helps in absorption of the nutrients and water from the soil for the growth and development of the whole plant.

The cell division in the plant body leads to the development of the roots, that is found in the soil providing the support to the plant to stand straight in the soil.

D, because cells create roots. B would work, but it is not directly responsible.

What are two diffrences between replication and transcription?

Ghella [55]

Replication - The action of copying or reproducing something.
DNA replication of producing two identical replicas of DNA from one original DNA molecule.

Transcription - First step to gene expression, in which a particular segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase. Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language.

1.) Transcription involved both DNA and RNA, whilst replication only involves DNA.
2.) Replication uses two identical replicas of DNA, whilst transcription is copied.

Hope I helped.

taurus [48]

Answer:

(A) Benthic- Benthic refers to the lowest or the bottom zone of the water body such as seas, and oceans. The organisms existing under such extreme pressure conditions are commonly known as benthic organisms. For example, corals and bivalves.

(B) Pelagic- Pelagic refers to the upper top portion of a water body, covering the open sea areas. The organisms existing in this region include dolphins and sharks.

(C) Sessile- Sessile refers to the property where an organism is stationary and cannot move freely from one place to another. These are known as sessile organisms such as coral polyps, Mussels.

(B) Mobile- refers to the property by which an organism can move freely in any direction it wants. For example, fishes, dolphins.

(E) Evisceration- It is a specific type of property where organisms can eject their internal organs in order to protect themselves from predators. for example, Sea cucumbers.

(F) Chitin- Chitin is a hard shell that is present in various organisms, forming its exoskeleton, for defense purposes. For example, arthropods.
