Answer:
The correct answer is B.
Explanation:
DNA was discovered in 1800, and then scientists studied DNA with X-Rays. After a while, scientists published a 3D model of DNA, and shortly after, scientists decoded DNA genes. So the answer is Option B.
Hopefully, this helps! :D

Explanation:
Phytoanticipins are defined as defense compounds which are constitutively present, i.e., regardless of the presence of pests or diseases.
Which mode of inheritance produces heterozygotes with phenotypes that differ from either homozygote but typically more closely resembles one homozygous phenotype than the other?"
A) complete dominance
B) incomplete dominance
C) codominance
D) epistasis
E) incomplete penetrance
Answer:
B) incomplete dominance
Explanation:
Incomplete dominance occurs when the dominant allele of a gene is not able to mask the expression of the recessive allele completely. This results in the expression of a phenotype in the heterozygous genotypes that differ from both homozygous genotypes. However, the phenotype of the heterozygote is closer to one of the homozygous genotypes.
For example, the petal color in four o'clock plant is controlled by a gene with two alleles R and r. Here, the "R" allele can not produce enough pigment in heterozygous conditions to completely mask the expression of the "r" allele and the phenotype of the "Rr" plant is "pink". On the other hand, the phenotype of "RR" plant is red while that of the "rr" plant is "white".
The correct answer is the first statement.
In intraspecies competition, there is a competition for recourses among the individuals from the same species. This is due to the limited availability of the recourses in the habitat. Only the fittest individuals will be able to gather enough recourses and survive.
Answer:
B. sheet of connective tissue that attaches a muscle to another muscle or bone.
Explanation:
The aponeurosis are mainly made of collagen fibers and works as an insertion to some skeletal muscles. The aponeurosis fibers can connects muscles to the bone or with another muscles connecting the aponeurosis fibers among themselves.
