<span>Genetic variation in bacterial made it possible for some individuals to have resistance to the antibiotic, survive, and reproduce is a statement that explains the theory of evolution very well. Some of the bacteria that became resistant to the antibiotics, passes this down the genes for drug resistance. I hope the answer helps you.</span>
Answer:
The correct answer would be- 1:1:1:1.
Explanation:
According to the question the cross between the two pea plants with the genotype RrYy and rryy where R for round seeds and r for recessive form that expressed wrinkled seed character. The other character of this dihybrid cross is the color of the seds Y for green and y for yellow seeds.
The cross is shown in the image attached that suggests that phenotypic ratio would be 1:1:1:1 as RrYy, Rryy, rrYy, and rryy.
Thus, the correct answer is : 1:1:1:1.
Answer:
Normal force, gravity and Friction.
Explanation:
The forces acting on the book are normal formal force which act or exerts by the table on the book while on the other hand, gravity is a force that acts in the downward direction. Friction is the force that acts against the motion of the book and is responsible for lowering speed of the book that is sliding on the surface of the table. If the friction is low between the book and table then the book moves easily on the surface.
I think it is the secondary ovarian follicle that contains the secondary oocyte.The stages of the ovarian cycle that the follicle will go through includes; a primary follicle contains an oocyte and begins producing estrogen. Then the secondary oocyte contains a secondary oocyte and produces estrogen and some progesterone, then the graafian follicle develops and the secondary oocyte is released a process we call ovulation. the corpus luteum produces progesterone and some estrogen and lastly the corpus luteum degenerates.
The alveolus (singular form) or alveoli (plural
form) are tiny sacs of organs that are attached to the ends of the alveolar
duct. These tiny sacs of air are clumped together that form interconnected
caves, working together as a unit. They are found inside the lungs and they
make the exchange of air easy and possible. Alveoli units are responsible for
putting oxygen into the air that we breathe in. Blood that passes through the
heart and into the lungs are converted into oxygen which will be then
transported by the blood all over the body systems.
<span>
The walls of the alveoli are extremely thin to
enable the quick exchange of gases Aside from this, the linings of alveoli
units are fluid in nature enabling gases to dissolve. </span>
