Answer:
function as energy storehouses, and function as important signaling molecules
Explanation:
The right answer is B and C.
For proposal C, I will give you an example, that of an autosomal recessive disease. If a parent is heterozygous for an allele causing an autosomal recessive disease (due to a mutation), it may be that it transmits the allele to its descendence, as it may not be able to transmit it (since in one heterozygous subject, not all of its gametes carry the mutated allele) and thus the mutation will no longer be copied through the generaitons.
Each individual is genetically unique. Its genes are distributed along chromosomes contained in the nucleus. Mutations can lead to the appearance of different versions of genes: alleles. A diploid individual has two copies of each gene, which may be identical or different alleles. Mixing during sexual reproduction partly explains the genetic diversity of individuals.
Answer:
Answer is C
Explanation:
Each cell has an identical copy of DNA with enzymes controlling the expression of specific genes leading to a variety of cells
Answer:
in science Observation is essential in science. Scientists use observation to
collect and record data, which enables them to construct and
then test hypotheses and theories . Scientists observe in many
ways – with their own senses or with tools such as microscopes,
scanners or transmitters to extend their vision or hearing
