Answer:
Males use a protein to detect pheromones sent by females.
Protein work as a chemical signal for the mating.
Explanation:
Pheromones are secreted by the individual of the similar species and they provide signals for communication by releasing a protein substance, they are like alarm substances.
This protein helps to guide females and males so that reproduction can occur.
Females beetles released sex pheromones into the environment, which give a signal of their mating availability.
Then these pheromones are detected by receptors present on the male beetles, and in this way, they find the females for mating .

(B) Protein-coding genes and noncoding DNA make up about the same amount of the human genome.
(C) Protein-coding genes make up far more of the human genome than noncoding DNA.
(D) Noncoding DNA has not been found in humans.
Answer:
(A) Protein-coding genes make up far less of the human genome than noncoding DNA.
Explanation:
The human genome contains both protein-coding and non-coding sequences. However, the non-coding sequences make most of the human genome as they account for as much as 98.5% of the total human genome. The non-coding part of the human genome serves other important functions such as promoter, enhancers, silencers for gene expression.
An only small part of the human genome serves as protein-coding genes and make exons.

Surface mining destroys vegetation and affects soil strata. Mining disrupts to topsoil microorganisms. Reclamation operations that dilute topsoil with subsoils can degrade soil.
Surface mining is a type of mining in which the soil and rock covering the mineral deposits are removed. It's the other way to mine underground. The rock on top is left in place, and the needed minerals are taken out through shafts or tunnels.
Surface mining can hurt fish and aquatic resources by causing erosion and sedimentation, drying up wetlands, rerouting and channelizing streams, and putting toxic chemicals into the surface water and aquifers.
This will further disrupt plant life on surface.
