Answer:
A
Explanation:
<em>The field of </em><em>recombinant DNA technology</em><em> is a thoroughly modern discipline that has led to new ways to treat infectious diseases.</em>
<u>Recombinant DNA technology involves the process of combining DNA of different organisms and inserting such in a host organism in order to elicit desirable genetic characters that could be of value to different fields in science.</u>
The fields in which recombinant DNA technology has found applications include agriculture, medicine, and industrial productions. With this technology, new drugs and methods of treating diseases have been developed in the area of medicine, disease-resistant crop varieties have been developed in agriculture, and important chemicals for production have been developed in industries.
<em>Correct option:</em><em> A</em>
Answer and Explanation: The farmer has a pure-breeding line of tomato means the farmer has a tomato with genotype FFrrtt while the other line of tomato has genotype ffRRTT.
The cross between these lines gives a F1 generation of heterozygous full, red and axial or FfRrTt.
With an individual of F1 crosses with another individual of F1, the Punnet Square will be:
FfRrTt x FfRrTt
1) Dividing each characteristics, for simplicity:
F f
F FF Ff
f Ff ff
R r
R RR Rr
r Rr rr
T t
T TT Tt
t Tt tt
Analysing Punnett squares, we notice the line wanted (ffrrTT) will be produced, when an individual of F1 generation cross with another individual with the same generation.
For walking, a group of four muscles, known as Quadriceps muscles are the most important. A complete bed rest for a longer period of time causes the reduction in the flexibility of the quadriceps. So, in order to prepare a person for ambulating after a long bed rest, the nurse should focus to restore the flexibility in the quadriceps. This can be done by alternating flexing and relaxing the quadriceps. This exercise would help in reviving the strength of the quadriceps.
They are formed primarily on the cell's Ribosomes.
Answer:
Reduction division: The first cell division in meiosis, the process by which germ cells are formed. In reduction division, the chromosome number is reduced from diploid (46 chromosomes) to haploid (23 chromosomes). Also known as first meiotic division and first meiosis.
