Transcription Initiation. The first step in transcription is initiation, when the RNA pol binds to the DNA upstream (5′) of the gene at a specialized sequence called a promoter (Figure 2a). In bacteria, promoters are usually composed of three sequence elements, whereas in eukaryotes, there are as many as seven elements ...

Answer:
The result of loss of topsoil are loss in fertility of soil, loss of water, crop production and hardened soil surface. Therefore, the correct answer to the above question is option A, B, C and D.
Explanation:
When there is a loss of top layer of soil from the earth by any means, natural or artificial, it is known as soil erosion. The soil from one place gets detached and is transported to another area. Planting more and more trees is the one of the way to stop soil erosion as the roots of the plants hold the soil.
When the soil from area is removed there is a loss of production in crop due to various reasons. The most fertile part of the soil occurs in the uppermost part. Therefore, its removal has negative impact.
Aspects such as genetic engineering have allowed for
engineering of transgenic organisms such as bacteria to produce bioproducts
such as insulin to addresses medical disorders
such as diabetes. Another is the innovation of whole-genome sequencing that allows researchers
to determine genetic predisposition of a particular person to particular diseases.
It’s B, having variation from sexual reproduction because the two parent mix genetic information so they have more of an advantage
