What causes variations in asexual organisms?

Biology
1 answer:
Nezavi [6.7K]2 years ago
8 0
<span>Variations in asexual organisms are rather rare since they occur as a result of mistake of mitosis during DNA copying. On the other hand, variations in sexual organisms are a result of fusion of two different gametes that carry different traits. Thus, the offspring carries characteristics of both parents, resulting in greater genetic variation within the next generation. Consequently, sexual organism obtain greater genetic variation than asexuallt reproducing species.</span>

Ivahew [28]

Answer:

The pectoralis muscle moves the front limb inward and the transverse abdominal muscles moves the posterior limiting membrane up. The limbs are brought into the shell, pushing up on the lung, causing air to expel by the muscles contracting.

To Breathe air in, the serrates muscle pulls out, the abdominal oblique pulls down and the weight of the viscera allows air to flow in, via negative pressure.

I can’t see your answer choices, but igneous rocks are made from cooled lava or magma. This is why these rocks are so brittle and grainy. I’ve attached a helpful image to better explain! Good luck!!!

Which part of the nephron receives fluid directly from the glomerular capsular space?
Gala2k [10]

The proximal tubule is the segment of the nephron in kidneys which begins from the renal pole of the Bowman's capsule to the beginning of loop of Henle. The glomerulus is the site in the nephron where fluid and solutes are filtered out of the blood to form a glomerular filtrate. The proximal and distal tubules, the loop of Henle, and the collecting ducts are sites for the reabsorption of water and ions. Fluid and small solutes are forced under pressure to flow from the glomerulus into the capsular space of the glomerular capsule.

Reabsorption as this filtrate passes through the tubules, specific substances are reabsorbed back into the blood of the peritubular capillaries. Bowman's capsule surrounds the glomerular capillary loops and participates in the filtration of blood from the glomerular capillaries.
