The answer is "Groundwater"
Answer:
Master genes tend to be conserved.
Explanation:
Master genes, which are the genes in the DNA that control major development processes such as the development of the skeleton, the organs etc and the production of the necessary proteins.
Since they take on such an important role, they don't really change much. Master genes that affect development tend to be highly conserved so embryonic development can show similar patterns.
I hope this answer helps.
A tool mark in a door frame contains small particles; The best way to collect them while leaving them in context is by making a cast. A tool mark is any impression, scratch, or abrasion made when contact occurs between a tool and an object. Abrasion marks are the tool marks made when surfaces slide across one another; objects such as pliers, knives, axes, or a gun barrel make this type of mark. There are three types of tool mark impressions; namely; indentation, abrasion, and cutting marks.
Answer:
The correct answer is an allele.
Explanation:
The variant form of a gene is termed as allele.Some genes exits as various different forms at a specific position on a chromosome also called genetic locus.
Humans are diploid organism.The diploid nature is due to the presence of two allele at each genetic locus among them one allele is inherited from paternal origin and the other allele is inherited from maternal origin.
The answer is C. They haven’t gone through physically restorative sleep and therefore may need to go to the doctor, especially if it happens often.
