B. Solvent behavior
C. Surface tension

Answers

There are some insects that can walk on water, this phenomenon is possible because the water has surface tension. One animal that can walk on water is the lizard. 
The behavior of water that is responsible for insects walking on the surface of water is surface tension. The correct option among all the options that are given in the question is the third option or option "C".Surface tension is basically the elastic nature of a fluid that helps it to acquire the least amount of surface area possible.

What was significant about the fossils Darwin found?

Answers

finding evidence such as Giant Sloths, breeds of horses, and hippos in environments which no longer had those existing animals was proof that survival of the fittest was important in climate changing locations.

The fossils discovered by Charles Darwin were effective when studied for evolution. These significantly proved the concept of survival of the fittest.

The phrase "survival of the fittest" was coined from Charles Darwin's evolutionary theory. He described how to describe the entire mechanism of natural selection and fittest meaning in this theory. Charles Darwin proposed the idea of the "survival of the fittest," which states that organisms that are most adapted to their environment have a higher chance of surviving and reproducing.

Examining reproductive success will reveal whether this biological notion of fitness is successful. The phrase "survival of the fittest" is best understood in Darwinian terms as "survival of the form that in successive generations will leave most copies of itself." The survival of the fittest theory, which stated that organisms better suited to their environment are more effective at survival and reproduction, first gained popularity in Charles Darwin's "On the Origin of Species" during its fifth season.

Therefore, the fossils were a proof of survival of the Fittest.

The following tests can be used for the diagnosis of premature rupture of membranes, except: a) Nitrazine test b) Ferning test c) Schiller's test d) Nile blue sulfate e) Evans blue test

Answers

Answer:

yes

Explanation:

Final answer:

The Nitrazine, Ferning, Nile blue sulfate and Evans blue tests can all be used for the diagnosis of premature rupture of membranes. Schiller's test is the outlier, as it is used primarily for identifying cervical dysplasia which is a precancerous condition.

Explanation:

The diagnosis of premature rupture of membranes, a condition in pregnancy where the amniotic sac breaks prior to labor, can be done using several tests. These include the Nitrazine test, where the pH of vaginal discharge is noted with a color change indicating rupture, the Ferning test seeing a pattern resembling fern leaves on a microscope slide due to the presence of amniotic fluid, and the Nile blue sulfate and Evans blue tests which involve instilling a dye and observing if it appears in vaginal secretions. Schiller's test, however, is unrelated to this diagnosis. It is used primarily to identify cervical dysplasia or precancerous changes in cervix by using iodine stain.
