The correct answer is option A, that is, a landfill in the region of nonporous bedrock.
A permanent waste disposal facility where the wastes are put into the ground and covered with a layer of plastic, soil, or both is known a landfill. A secure chemical landfill refers to a landfill developed in the region of nonporous bedrock.
A secure chemical landfill is a prudently engineered depression in the ground or constructed on the top of the ground, signifying a football stadium into which wastes are dumped. The objective is to inhibit any water-related or hydraulic association between the surrounding environment and the wastes, mainly groundwater.
Answer:
Yes
Explanation:
Range rule of thumb predicts the Range to be a multiple of 4 of the standard deviation or to be four times the standard deviation. Making the usual values equal to 2 standard deviations distanct of the mean of the data distribution.
In a given distribution with mean and standard deviation that is obtained, the usual values in mean (as seen in the attached image).
2*standard deviation and mean + 2*standard deviation.
If the data point is not up to the mean
- 2* standard deviation is taken to be significantly low.
If the data point is more than the mean
+ 2*standard deviation is taken to be significantly high.
Let's take the xbar to be the mean and s as standard deviaiton
Given,
mean, xbar = 1116.2
standard deviation, s =127.7
The range rule of thumb shows that the usual values are within 2 standard deviations from the mean
Lower boundary
= xbar - 2s
= 1116.2 - 2(127.7)
= 860.8
Upper boundary
= xbar + 2s
= 1116.2 + 2(127.7)
= 1371.6
We should note that 1411.6 is not between 860.8 and 1371.6, which connotes that 1411.6cm^3 is unusually high.
Answer:
The cornea acts as the eye's outermost lens. It functions like a window that controls and focuses the entry of light into the eye. The cornea contributes between 65- 75 percent of the eye's total focusing power.
Or you can answer :
The cornea is the transparent part of the eye that covers the front portion of the eye. It covers the pupil (the opening at the center of the eye), iris (the colored part of the eye), and anterior chamber (the fluid-filled inside of the eye). The cornea's main function is to refract, or bend, light.
Whales have pelvic (hip) bones, which are evolutionary remains from when their forefathers walked on land about 40 million years ago. Common belief has long assumed that such bones are merely vestigial, slowly withering away like human tailbones. Thus option C is correct.
<h3>What is the new research from USC and the Natural History Museum of Los Angeles County (NHM) has to say ?</h3>
New research from USC and the Natural History Museum of Los Angeles County (NHM) contradicts this belief, discovering that not only do those pelvic bones have a role, but their size and perhaps shape are impacted by sexual selection processes.
Therefore, small, shrunken hip bones of whale are no longer beneficial for survival and are considered vestigial. So, the best option is C among the other options available. Thus option C is correct.

Answer:
tertiary; quaternary
Explanation:
The orientation of all the atoms of a protein in three dimensions represents its tertiary structure. It includes the folding of the polypeptide chains in a way that brings are far apart amino acids of its secondary structure close together. Various segments of a polypeptide chain interact to form tertiary structures and these segments are held together by different kinds of weak interactions.
However, disulfide cross-links between the segments of polypeptide chains also stabilize the tertiary structure of some proteins. Likewise, disulfide bonds also hold the protein subunits of some proteins together and thereby, contribute to the quaternary structure. For example, two light chains of an antibody are joined together by disulfide bonds.
