Biological diversity is the variety of species in a given area. If a new species is added there are more species and therefor greater biological diversity and if one goes extinct there are less species and therefore less biological diversity.

babunello [35]

<u>Answer:</u>

CCGAGU

<u>Explanation:</u>

DNA transcription:

DNA transcription is the process through which DNA double helical strand is converted into single stranded RNA molecule.

During transcription two strands of DNA are named differently i.e Template strand and coding strand.

Template strand:

Strand from which RNA is producing is known as template strand while

Coding strand:

The strand which is opposite to the template strand is known as the coding strand. Coding strand is the DNA strand whose nucleotide sequence resembles to the RNA transcript base sequence except thymine which is replaced by uracil.

Correct Answer:

Template strand from 5' to 3' reads GGCTCA. and

In this question CCGAGT is coding strand.

RNA sequence is same as coding sequence except T which is replaced by U so sequence of RNA becomes

Nina [5.8K]

Answer:

This question is incomplete and lacks options, the whole question is:

Plant hormones serve as chemical messengers between cells and tissues. Auxin is a plant hormone that causes the cells on the shady side of a plant shoot to elongate. The response enabled by auxin is known as -

Options are:

A. geotropism

B. transpiration

C. phototropism

D. photosynthesis  

The correct answer is c.

Explanation:

Phototropism is known as a natural and organic movement of a plant towards the light. This is due to the natural ability of a plant to change direction based on changes in lighting in the environment. But external stimulus is not enough. It must generate some changes inside the plant that make it react in this way: hormones. A hormone is a chemical substance produced in one tissue and transported to another, in which it exerts one or more highly specific effects.Auxins are members of a group of plant hormones that are more beneficial to stimulate plant growth, it is the responsible mechanism of the response to phototropism in plants, which tends to be concentrated in the region of the stem and leaves, when a plant lacks this, it can be noted since the bending towards the light source is little or no, that is, auxins make the cells of the stem growth region (rhizomes and stems) lengthen.
