Answer:
we will know that the allelic frequencies are for R 0.95 and r 0.05
Explanation:
We know that the population is in Hardy-Winberg equilibrium, we deduce the following formula:
p + q = 1
p2 + 2pq + q2 = 1
data
R: red flower allele
r: allele blor blanca
p would be equal to the allelic frequency R
q will be equal to the frequency allelic r
2p = RR
2q = rr
2pq = Rr
If there are 25 white flowers in 1000 plants, their frequency will be:
2pq frequency of the Rr genotype
white flower = 25/10000 = 0.0025 = rr = 2q = 0.0025
we deduce that q is equal to 0.05
we replace the data with the previous formula
p + q = 1
p = 1-0.05
we get as a result
p = 0.95
if p = 0.95 and q = 0.05
we will know that the allelic frequencies are for R 0.95 and r 0.05
Answer:
<em>The correct option is A. X, because organism X has the same role as the grasshopper</em>
Explanation:
In a food chain or a food web, a primary producer can be described as an organism which feeds on producers. The producers, in this case, are the corn stalks. Grasshoppers are primary consumers in this food web because they feed on the corn stalks. X is also a primary producer, just like grasshopper, because it feeds on the corn stalks which are the producers. Hence, option A is correct.
Answer:
Chromosomes are passed from parents to offspring via sperm and eggs. The specific kind of chromosome that contains a gene determines how that gene is inherited. ... Consequently, each person has two copies (alleles) of every gene carried on an autosome: one inherited from their father and one from their mother.
Like chromosomes, genes also come in pairs. Each of your parents has two copies of each of their genes, and each parent passes along just one copy to make up the genes you have. Genes that are passed on to you determine many of your traits, such as your hair color and skin color
Answer:
excretory system
Explanation:
The excretory system is the system of an organism's body that performs the function of excretion, the bodily process of discharging wastes. ... There are several parts of the body that are involved in this process, such as sweat glands, the liver, the lungs and the kidney system. Every human has two kidneys.
Answer:
A. Enzymes break up glycogen from its non-reducing end one glucose at a time.
Explanation:
Glycogen is a polysaccharide made up of glucose moieties and serves as energy stores in animals, bacteria and also fungi.
Glycogen is degraded or broken down by an enzyme called glycogen phosphorylase. Glycogen phosphorylase hydrolyses glycogen to produce glucose-1-phosphate and glycogen molecule short of one glucose. This enzyme only catalyzes from the non reducing end of a glycogen where terminal carbon is free of ketone or aldehyde group.
