Which type of mining is likely the least harmful to the environment?
a. surface mining
b. placer mining
c. subsurface mining
d. none of the above
Answer:
Placer mining
Explanation:
Placer mining can be less damaging to the environment than surface mines, as the sediment is returned to the water after the minerals have been extracted.
The mining that is likely the least harmful to the environment is the placer mining that is present in Option B, water is used in placer mining to separate mineral particles from soil.
What is placer mining?Placer mining involves the extraction of minerals from riverbeds, streambeds, and other bodies of water, and this method involves the use of water to separate mineral particles from soil, while placer mining is generally considered to be less harmful to the environment compared to surface and subsurface mining, but it can still have negative impacts if not properly managed. For example, the use of mercury in the gold extraction process can lead to water pollution and harm to aquatic life.
Hence, the mining that is likely the least harmful to the environment is the placer mining that is present in Option B.

the skull of a mammal has no sharp canine teeth. the large teeth in the back of the jaw are very flat. what did this mammal eat?
Mammals' skulls, as well as their dentition, may provide us with information about their diet. The skull of a mammal that lacks sharp canine teeth and has broad, flat molars, is likely to be herbivorous.
Furthermore, the molars' flat shape indicates that the mammal is probably a grazer that consumes grass or tough vegetation. In contrast to carnivorous mammals that use their sharp, pointed canine teeth to tear flesh and their molars to shear meat into smaller pieces, herbivorous mammals use their flat, wide molars to grind and crush tough vegetation.
The molars are often covered in ridges and crests, which increase the surface area of the teeth, allowing them to break down the fibrous plant material into smaller pieces that can be more easily digested. The molars are frequently continually expanding throughout the animal's life, allowing the animal to continue to grind up vegetation even as its teeth become worn down due to constant use.
The skull and teeth of a mammal provide important clues about its lifestyle, feeding habits, and ecology, and scientists can learn a lot about past animals by studying their bones.

the comet that hit jupiter raised fiery plumes large enough to incinerate the ________
Answer:
The comet ventured too close to Jupiter's mighty gravitational pull two years ago and was pulled apart into a score of large fragments and thousands of small ones. As each fragment hits Jupiter's dense atmosphere, it is stopped as if it had hit a brick wall. In an instant, its initial speed of 130,000 miles per hour is reduced to zero, and practically all of its gigantic kinetic energy is converted to heat -- so much heat that a titanic explosion results. In the case of each of the largest fragments, this is equivalent to 250 million megatons of TNT. (The largest hydrogen bomb ever detonated produced a blast equivalent to about 58 megatons.)
Explanation:
Could the speed at which molecules diffused over the dialysis tubing been slowed down or sped up? If so, explain how.
The speed at which molecules diffuse over dialysis tubing can be influenced and either slowed down or sped up.
Could the molecules speed up?
In general, smaller molecules disperse faster than larger ones. The diffusion rate would be slower if the molecules attempting to pass through the dialysis tube were larger in size. On the other hand, smaller molecules will disperse more quickly.
Diffusion is greatly influenced by the concentration differential between the two sides of the dialysis tube. Diffusion will happen more quickly if there is a steep concentration gradient (a big variation in concentration). Diffusion will move more slowly if the gradient of concentration is small.

What type of natural selection do you think is acting on these bugs if we consider the golden rain tree bugs and balloon vines bugs together as one group
Complete question:
Question 49 (1 point) The following questions refer to the description below. You have read that soapberry bugs, Jadera haematoloma, adapt to available food sources. For example, in southern Florida, soapberry bugs feed on seeds of a native plant, the balloon vine. In central Florida, the balloon vine is rare and soapberry bugs have switched to eating seeds of an introduced species, the golden rain tree. The seeds of the golden rain tree fruits are much closer to the fruit surface than the seeds of the native balloon vine fruit. As a result, natural selection results in beaks that are shorter in soapberry bugs that utilize golden rain tree fruits than those that feed on balloon vine fruit seeds.

Which is NOT an environmental factor that will influence an organism's behavior?A)Number of stars in the skyB)The amount of food availableC)The amount of water availableD)The average daily temperature
Answer
A - Number of stars in the sky
Explanation
The number of stars in the sky will NOT affect an organisms behavior.
The amount of availability of food, water and daily temperature would influence the behavior of an organism as these are important factors of survival, but the number of starts in a sky would not influence the behavior of an organism. Thus, option A is the correct answer.
The number of stars in the sky does not depends on any factor that is related to an organism to live and survive. An organism would always behave and live according to its need. Hence, an organism does not need to be aware of the number of stars in the sky to thrive.
The environmental factors that influence the behavior of an organism are- the availability of food, water, increasing and decreasing temperatures. The availability of food and water influences the behavior of and organism as it is an important factor for the organism to survive. Also, the fluctuation of temperature is also an influencing factor as excess increase or decrease of temperature would make the environment for an organism inhabitable.
