How does sexual reproduction compare to DNA transfers in prokaryotes? (2 points)

Biology
1 answer:
Andreyy894 years ago
7 0

Answer:

The correct answer is b. I and II

Explanation:

Sexual reproduction is present in higher forms of life and absent in prokaryotes like bacteria. Sexual reproduction results in greater evolutionary changes due to the fusion of two different gametes from two different individuals of a species.

Therefore sexual reproduction helps in increased genetic diversity in higher forms of life. In prokaryotes like bacteria, genetic diversity is maintained and increased through DNA transfer from one bacterial cell to another with the help of a process known as horizontal gene transfer.

Bacteria have sex pilli which is used to introduce the genes to the other bacteria. By this process, they increase their genetic diversity and evolve continuously. So the correct is b. I and II.

Describe the structure of the kidney and include structure of nephron as well
asambeis [7]

Answer:

Generally, mammals have a pair of bran-shaped kidneys. The mammalian kidney has 2 distinct regions, an outer renal cortex and inner renal medulla. Both regions are packed with microscopic excretory tubules, nephrons, and their associated blood vessels. Each nephron consists of a single long tubule and a ball of capillaries, known as glomerulus. The blind end of the tubule forms a cup-shaped swelling called Bowman’s capsule, that surround the glomerulus. From Bowman’s capsule, the filtrate passes through 3 regions of the nephron which are proximal tubule, the loop of Henle. A hairpin turns with a descending limb and an ascending limb and the distal tubule. The distal tubule empties into a collecting duct, which receives processed filtrate from many nephrons. The many collecting ducts empty into the renal pelvis, which is drained by ureter.

For the structure of nephron, each nephron is supplied with blood by an afferent arteriole, a branch of the renal artery that subdivides into the capillaries of the glomerulus. The capillaries converge as they leave the glomerulus, forming an efferent arteriole. It is surrounded by the Bowman’s capsule. The double-walled epithelial Bowman’s capsule is formed by the invagination of the blind end of the nephron. The glomerulus and Bowman’s capsule form the first region of the nephron and is known as the renal corpuscle or the Malpighian body. The capillary walls are composed of a single layer of endothelial cells with openings between them with a diameter 50-100nm. These cells are pressed up against basement membrane which completely envelops each capillary, separating the blood in the capillary from the lumen of Bowman’s capsule. The inner layer of the Bowman’s capsule is composed of a cell called podocytes which have arms that give off structures resembling tube-feet called foot processes or secondary processes. The secondary processes support the basement membrane and capillaries beneath it and gaps between the processes (slit pores) facilitate the process of filtration. The Malpighian body leads into the remainder of the tubule.

<u>Answer:</u>

An increase in carbon dioxide in the atmosphere will MOST likely  affect C: Cave formation rates .

<u>Explanation:</u>

"Carbon-di-oxide" is an important gas which 'controls' the Earth's temperature. CO2 including methane are greenhouse gases which absorb a lot of energy and then re-emit it. Without these gases, earth would get frozen. But, if these gases are in excess, then temperature of earth would rise like that of Venus, up to 400 degree Celsius.

If CO2 increases, there will be an increase in cave formation activity. Rain water takes CO2 from the air and penetrates in the soil. This results in formation of "limestone" as 'carbonate' accumulates in the soil. This forms 'cave of limestone' with the help of 'groundwater' as limestone dissolves easily in water.
