Answer:
The correct answer is - option B. DNA sequences from different species can be compared, giving us more information about their evolutionary relationships.
Explanation:
The study of the evolution of a species in a longer period of time and its evolutionary relation with other species is phylogeny. DNA is the basis of the molecular phylogeny of a species to find out the evolution of species.
Genetic mutations, a sequence of nucleotides, and other information of DNA helps in the establishment of divergence from common ancestry. By comparing the information it gives an idea about the evolutionary ancestry of two or more species.
Answer:
in a human 46 chromatids form 23 chromosomes
Explanation:
Turner pressure is simply the force within the plant cell that pushes the cell membrane or plasma membrane against the cell wall.
It is caused by the Osmotic flow of water through the semi permeable membrane.
It helps the plant cells to remain turgid and stand tall so as to prevent it from wilting
Answer:
no
Explanation:
synthetic folic acid is way more harmful then the natural folate in foods, it may build up in the body and raise cancer, and synthetic copies of natural chemicals are not as good for you
Answer:
Phenotype genotype Number of individuals
Red RR 245
Pink Rr 210
White rr 45
Number of alleles in total
R = 245 + 245 + 210 = 700 ---> 700/1000= 0.7 R frequency
r = 210 + 45 + 45 = 300 -----> 300/1000 = 0.3 r frequency
Predict (Hardy Weinberg) genotype frequencies=
p^2 + 2pq + q^2 = 1
p= 0.7
q=0.3
0.49 + 0.42 + 0.9 =1
According Punnett Squares in F1 we have=
Rr* rr = Rr 50% and rr 50%
