I'm assuming this is the same image that was posted before, therefore the answer is "gene flow" which occurs through population groups by natural selection and other factors.
Answer:
lysosomes, small molecules
Explanation:
-plants:usually not evident Animals: occurs in cytoplasm
-small organelles filled with enzymes
-"clean up crew"
- the digestion or breakdown of lipids, carbs, and small proteins into small molecules that can be used by the rest of the cell
-involved in breaking down organelles that have outliveed their usefullness
-diseases are trace to lysosomes that dont function properly
In human gene therapy, a genetically modified virus (a.k.a. a viral vector) can alter the genetic variation of a cell, but not all viral vectors do.
The process often begins with the delivery of or creation of a segment of viral double stranded DNA (containing the gene you want to introduce). Then typically an enzyme known as an integrase cuts the ends of the segment of viral DNA and also cuts open the cell's DNA. Then the viral DNA is integrated/ inserted into the cell's DNA. The connecting ends are ligated together and adjusted so that the nucleotide base pairs match up.
This in the future may affect the gene pool for instance if the viral DNA (your gene) was inserted in the middle of another gene or important regulatory sequence of the cell DNA, and this alteration may be passed on into offspring and become present in the gene pool, which could have bad effects.
The effects on the gene pool really depends on what the virus ends up doing. For example, it may fix the function of a damaged gene which is the goal, and allow for a working gene to be in the gene pool, which would be good. The problem with gene therapy is that it's difficult to predict 100% what the virus will do every time it is given to a patient.
But it's very important to consider that it will only affect the gene pool if the virus is able to enter and alter germ cells (reproductive cells). If the virus, enters somatic cells (regular body cells) this will not be passed on to future generations. So viruses can be designed to avoid germ cells and avoid this gene pool issue. Also, some viral vectors use viruses that do not integrate their DNA, the cells just express the viral DNA (create the desired protein from it) and over time the viral DNA is degraded/ lost which wouldn't pose this threat.
This is long, but I hope it helped!
Nonmetals take electrons from the metals they are attracted to in order to become stable.
Answer:
The correct answer will be option-C
Explanation:
Louse-bourne relapsing fever is a disease which is characterised by having the muscle aches and the episodes of fever.
The disease is a vector-borne disease in which the pathogen spirochete <em>Borrelia recurrentis</em> which lives in the gut of the body louse- <em>Pediculus humanus humanus </em>completes its life cycle and when body louse is crushed gets released on to the human skin and thus penetrates the humans. The disease could prove fatal if no treatment is provided at the right time.
Thus, Option-C is the correct answer.
