Answer:
Frequency of genotype RR
Frequency of genotype RY
Frequency of genotype YY
Explanation:
Total number of species
Genetic frequencies of the snake population is equal to number of species of a given genotype divided by total number of species.
Thus,
Frequency of RR
Frequency of RY
Frequency of YY
Answer:
Explanation:
Such farming system increases production to meet the demands of Nigerians. Proper processing of waste and related substances increases the profit of farmers. Intensification of crops growth maximizes income in relation to area, time and efforts
Answer:
Please find the mRNA and amino acid of the DNA sequence in the table below.
Explanation:
This question is describing the processes of transcription and translation. Transcription is the synthesis of mRNA from a DNA template while translation is the synthesis of an amino acid sequence from a mRNA sequence.
The following nucleotides combination are given in this question. Their transcription into mRNA using the complementary base pairing rule is as follows;
DNA = mRNA
- ATG = UAC
- GTA = CAU
- CAA = GUU
- AAT = UUA
- GCG = CGC
- TGT = ACA
- ACT = UGA
- CCC = GGG
- TAG = AUC
Using the codon chart attached as an image, the translation of these mRNA codons is as follows:
mRNA = amino acid
- UAC = tyrosine (tyr)
- CAU = histidine (his)
- GUU = Valine (Val)
- UUA = Leucine (leu)
- CGC = Arginine (Arg)
- ACA = threonine (Thr)
- UGA = STOP codon
- GGG = Valine (Val)
- AUC = Isoleucine (Iso)
The correct answer is xylem.
<span>Xylem is a type of plants’ transport tissue. The function of the xylem is to transport water and solutes from the roots to the leaves. The xylem transport system is composed of continuous tubes called xylem vessels. Xylem vessels enable transport (after absorption from the soil through root hair cells) up the stem to the leaves. Water evaporation from the leaves (transpiration) is also mainteined by xylem. Xylem vessels consist of dead cells with a thick, strengthened cell wall with a cellulose and hollow lumen. Vessel element is one of the cell types found in xylem and together with tracheids, is involved in the actual transport.</span>
