Part of us humans daily life.
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.
It’s either A or B
Diseases can often cause a decrease in the population
But also without healthy grass for them to eat, they begins to die off cause of not a lot of food left for them to eat enough to survive.
Answer:
<h2>1.45 + 3.55 = 5.0 (total blood volume); 1.45/5.0 × 100 = 29% (low),</h2>
Explanation:
HCT is calculated as:
HCT = Volume of red blood cells / (Volume of red blood cells + volume of plasma) x 100
1.45 + 3.55 = 5.0 (total blood volume); 1.45/5.0 × 100 = 29% (low), normal range for an adult female HCT ranges from 38 to 46% (some sources claim 34.9-44.5%).
*for calculating this, one must know two of these three values: packed cell volume, total blood volume, plasma volume.
Total blood volume = Packed cell volume + plasma volume.
Answer:
B. 25%
Explanation:
Assuming the trait for teeth size is represented by the allele A. large teeth size is dominant and will be represented by A while small teeth size will be represented by a.
Assuming that the population of 1,000 [piranhas are all heterozygotes and they crossbreed with one another:
Aa x Aa = AA, Aa, Aa and aa
The ration of piranhas with large teeth to that of the small teeth is 3:1 or 75:25.
Hence, about 25% of the next generation of the population is ecpected to have small teeth.
The correct option is B.
