A well mixed serial dilution is critical to achieving a homogenous mixture that has a constant concentration over the sample volume. If the dilution is not well mixed then it will affect the subsequent dilutions consent ration which will lead to percent error

Using at least two examples, explain how the process of evolution is revealed by the imperfections of living organisms.
Serga [27]

Answer:

Evolution is driven by rare mutations that occur in the DNA of organisms. These mutations  could be lethal, neutral and some advantageous. The lethal mutations cannot exist in a population because the offspring is unable to survive to term in pregnancy or dies just after birth. The neutral are ones that do not considerably affect the organisms – though they could result in a disadvantage. The beneficial ones are the one that is kept in the population by natural selection because they confer an advantage e.g in the fight for resources or escaping predation and etcetera. Therefore, it's like a game of chances by nature. Paleontologists discover many species of organisms some of which are imperfect  because nature produced them but they died off because their mutations gave them a disadvantage against better-adapted individuals.

The <em>Tiktaalik</em> fish from 375 million years ago became extinct because it did not well-developed eardrum for detecting vibrations in water which is significant in survival.

Dinosaurs during development of feathers had many imperfect species before the right wings for flight were conjured up by nature. An imperfect species is the <u><em>Tianyulong confucius</em></u> had stiff feathers that lacked vanes hence were not ideal for flight

arrange the process of hemostasis in sequence. (separate letters by a comma and space [ex. a, b, c,…])
Nina [5.8K]

The sequence for the process of hemostasis is A, F, B, C, D, E.

<h3>What is Hemostasis?</h3>

Your body's natural response to an injury, hemostasis, stops the bleeding and repairs the damage. This skill typically works to your advantage by preserving blood and avoiding infections. The process can occasionally malfunction, leading to issues with excessive or insufficient clotting. There are four distinct steps to the hemostasis mechanism.

1) Blood vessel constriction.

2) The development of a transient "platelet plug."

3) The coagulation cascade is activated.

4) The last clot, or "fibrin plug," forms.

A series of enzymatic activations that result in the development of a clot containing platelets and fibrin polymer are made easier by hemostasis. While the process of tissue regeneration is taking place, this clot plugs the wounded area, manages the bleeding, and stops further bleeding.
