Conjugation and transformation are both kinds of horizontal gene transfer that allow a cell to receive and recombine external DNA. Conjugation involves physical contact between two bacteria using a pilus, through which a copy of plasmid DNA is transferred from the donor (F+) cell to the recipient (F-) cell. Transformation, on the other hand, is simple uptake of naked DNA into a recipient cell from the environment. The DNA usually comes from the leftovers of a dead cell.
Answer:
The correct answer is B. In the human eye, the greatest amount of refraction occurs when the light passes from the air into the cornea.
Explanation:
The ocular refraction refers to the refraction that occurs in the light coming from the objects when crossing the different parts of the eye, causing the images to concentrate on the retina.
When the light rays, after crossing the cornea and the lens, are projected on the retina at a single point creating a clear image that is transmitted to the brain for processing, we talk about normal refraction.
Answer:
The correct option is 2 Nephrogenic diabetes insipidus.
Explanation:
Nephrogenic diabetes insipidus (NDI) occurs when the renal tubule response to vasopressin (ADH) is weakened, resulting in the excretion of large volumes of dilute urine.
As the renal tubules do not respond to vasopressin (antidiuretic hormone) and are unable to reabsorb filtered water back into the body, the kidneys create a high volume of dilute urine in nephrogenic diabetes insipidus.
Nephrogenic diabetes insipidus (NDI) can be inherited or develop as a result of disorders that impede the ability of the kidneys to concentrate.
Therefore, the correct option is 2 Nephrogenic diabetes insipidus.
That is, the most likely cause of his polyuria is nephrogenic diabetes insipidus.
<span>Scientist think convection currents are what cause earths plates to move. a convetion current is caused by the diffrence in the temperature, Mantle material close to the earths core is very hot. Mantle material near the lithosphere is cooler.</span>
