Answer:
The fertility factor or the F factor signifies a plasmid in some bacteria, which allows the conduction of genetic substance from a donor cell to the recipient by the process of conjugation, leading to recombination.
The genotypic difference between the F- cells, F+ cells, and the Hfr cells are that the F- cells are devoid of the F factor, the F+ cells possess autonomous F factor, that is, a segment of DNA, which can replicate autonomously in the cell. In case of Hfr, the F factor is integrated into its chromosomal DNA, thus, they carry an integrated F factor.
the answer is C.permeable.
Material that’s permeable means that it allows fluid(such as water), gas etc. to pass through it.
Answer:
organ cells
Explanation:
cells are the building of life
The most likely explanation is either they survive without the zooxanthellae entirely or off of an other type of bacteria.
Answer:
The understanding that alcohol is a potent teratogenic agent -capable of affecting the genetic expression of a developing embryo and fetus- is sufficient to support medical advice given to women to avoid consumption of alcohol during pregnancy.
Explanation:
A teratogen is a substance capable of affecting genetic expression - causing alteration and lack of regulation of the genes responsible for the form and function of a living being - and organ formation.
<u>Alcohol is a powerful teratogen</u>, responsible for fetal alcohol spectrum disorder, which includes disorder in the proper expression of genes and abnormal development of organs such as the heart, brain and limbs.
When a doctor suggests that a woman does not consume alcohol during pregnancy, he does so to prevent alterations that this product may cause in a fetus or embryo, as well as the death before birth.
