Animal Cells do not contain a (B Cell Wall) instead have a Plasma Membrane which is made up of I believe a lipid bi layer.<span />
Answer:
Option A 400 individuals
Explanation:
Using this formula, we can estimate the population size of the canvas backs as this is a capture-recapture method.
N = (MxC) / R
Where N = estimated Number of individuals in the population
M = number of individuals captured and Marked = 200
C = total number Captured the second time (with and without a mark) = 200 and
R= number of individuals Recaptured (those with a mark) = 100
Thus, we have
N = (MxC) / R
= (200 x 200) / 100
= (40,000) / 100
= 400 individuals.
Answer:
A. They do not use up any energy finding mates.
Explanation:
The asexual reproduction consists of one parent which are same to each other while on the other hand consists of two parent that produced unique.
For species survival, the reproduction of protozoa asexually rather than sexually could be better when they don't use much time and energy for determining the mates
Therefore in the given case the correct option is A.
Answer:
The correct answer is C.
Explanation:
The amount of genetic variation in two humans is 0.1 percent of their genome. Human genetic variation refers to the biological difference that exists in the human population.
The genetic variation in humans and apes genome is about 4 percent which is 35 million differences in a single nucleotide.
The genetic variation between apes and humans (Homo sapiens), according to scientists includes gene expression differences, variation in the transportable elements and type and number of repetitive genomic DNA transportable elements, the difference in the gene sequence, single nucleotide polymorphic, etc.
According to research, 97 percent of humans and orangutans genomes are identical. Based on evolution, among all apes, the orangutans are very special as it has been stable for the past 15 million years.
Therefore, is the genetic variation between humans and orangutans is the greatest.
