The answer is B, it is the only answer that talks about electric signals.
There are many known positive outcomes of genetic engineering both in plant and animals. Among these outcomes include: a. elimination of diseases; b. most desirable traits guaranteed to exist; c. crops that can be pest and disease resistant; d. longer shelf life for plants.
Answer: The genotype of the generation resulting from the given P ( parental generation) is Aa that is all offsprings in the first generation will be heterozygous dominant.
The genotype of the parents is AA and aa and the gametes produced by these parents are A and a respectively.
When these gametes fuse, they result in the offsprings with genotype Aa. This represents a dominant phenotype due to the presence of dominant gene ( a gene that masks the expression of recessive gene and expresses itself), which is A in this case.
D. Oxygen and metal
They usually contain some form of metallic cation, given that carbonates are the most distributed minerals in the Earth's crust.
