Answer:
A. The formation of fossil fuels
Explanation:
Human activities would have the least immediate impact on the formation of fossil fuels because the fossil fuels are not affected the formation of fossil fuels. The formation of fossil fuels takes millions of years because it is a very slow process. Human activities greatly affected the coral reef bleaching, over population and Eutrophication due to the release of pollutant gases in the atmosphere that greatly impact the environment.

ou have isolated a previously unstudied protein, identified its complete structure in detail, and determined that it catalyzes the breakdown of a large substrate. You notice it has two binding sites. One of these is large, apparently the bonding site for the large substrate; the other is small, possibly a binding site for a regulatory molecule. What do these findings tell you about the mechanism of this protein
Answer:
These findings tell us that possibly this protein has an enzymatic function, that is, it is an enzyme.
Its function can be catalytic as well as analytical.
The substrate binding site should be the largest, while the other regulatory site is the smallest.
Explanation:
This happens since hormones regulate their enzymatic activity through inhibitory sites.
They have another smaller binding site, where when an inhibitory molecule binds, it deforms the morphology of the protein causing it to no longer bind to its substrate at the binding site, therefore they inhibit the chemical reaction that is happening within the enzyme. both catalytic and analytical.
What is an anticodon?*

what is the function of cell nucleus?
Answer:
The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. The gel-like matrix in which the nuclear components are suspended is the nucleoplasm.

Which three statements contain information about cats that is based on scientific knowledge rather than opinion?
Answer:
First claim '' cats are very smart animal''. Second claim '' cats make bonds with humans''
oxygen transport in humans involves the bonding of oxygen with
A : white blood cells
b :platelets
C :Hormones
D Hemoglobin molecules
Answer:
i think it's d. hemoglobin molecules
Oxygen transport in humans involves the bonding of oxygen with hemoglobin molecules. Therefore, option (D) is correct.
Human oxygen transport is essential for delivering oxygen, a key gas needed for cellular respiration, to all tissues and organs. Haemoglobin molecules in red blood cells deliver oxygen.
Oxygen diffuses into the bloodstream and meets haemoglobin in the lungs. Oxyhemoglobin is formed when haemoglobin binds to oxygen molecules. Oxygen partial pressure and other factors affect reversible binding.
The heart pumps oxygenated blood via the circulatory system to tissues and organs. Oxyhemoglobin releases its oxygen, allowing cells to use it in cellular respiration to make energy. The mechanism efficiently supplies oxygen for metabolic needs. Life and physiological activities depend on this mechanism. Therefore, option (D) is correct.

Which scientific claim can be made? Songbirds numbers will increase due to the effects of climate change increasing global Temperatures
The scientific statement that can be made is that the imbalance in the food chain happened because of this fact, because the songbirds will harm other living beings by their growth.
What is an imbalance in the food chain?Ecological imbalance occurs when some element (animal or plant) of an ecosystem is reduced in
quantityadded or subtracted.This change can give rise to chain reactions and directly affect the functioning of the ecosystem.
With this information, we can conclude that the scientific statement that can be made is that the imbalance in the food chain happened because of this fact, because the songbirds will harm other living beings by their growth.

After examining the fossil record, scientists have determined that scorpions today are much smaller than their extinct ancestors. For example, Jaekelopterus rhenaniae, a giant scoprtion species that lived 255 million to 460 million years ago was 2.5 meters long. Which of the following conclusions is supported by this information?
A. scorpions living today have increased their numbers since they first appeared
B. scorpions in the fossil record are smaller than their descendants are
C. scorpions have changed as a result of natural selection
D. scorpions do not appear in their original state in the fossil record
Answer: C. scorpions have changed as a result of natural selection
Explanation:
The text tells us that scorpions today are now smaller than they were in the past. This means that the scorpions have changed since then i.e. they have evolved.
The primary reason for evolution is natural selection which refers to a situation whereby only the organisms that are better adapted in their species survive.
The conclusion that can be drawn from this research therefore is that we have smaller scorpions today because they stood a better chance of survival than the larger ones and so survived whilst the larger ones died out.

Which definition is the best for “semipermeable membrane
Answer: A semi-permeable membrane is that which only allows certain
substances to pass through.
Answer: A semipermeable membrane is a layer that only certain molecules can pass through. Semipermeable membranes can be both biological and artificial. Artificial semipermeable membranes include a variety of material designed for the purposes of filtration, such as those used in reverse osmosis, which only allow water to pass. The biological membranes of cells are created by two sheets of phospholipid, which contain a lipid tail attached to a polar head. The tail regions of each sheet cluster together, while the heads of the molecules point outward. The polar heads point both outward toward the environment of the cell and inward toward the cytosol. In this way, a hydrophobic region of lipid tails separates the two bodies of solution. This can be seen in the image below.

Most renewable resources are clean and nonpolluting.Renewable resources can be replenished.Most renewable resources are easily available in nature.Thus, the correct options are A, B, and C.
What are Renewable sources of energy?Energy sources that are renewable are defined as those that miraculously come from natural sources and are replenished or recharged more quickly than they are actually consumed.
These energy sources are based on the idea of sources which are continuously replenished more quickly. Most of the time, this energy is produced in a clean, non-polluting manner. Since renewable energy comes from natural resources, it is substantially cheaper or free to get renewable energy in nature.
Therefore, the correct options are A, B, and C.

Answer:
time: 1.122 secondsrange: 10.693 mmaximum height: 1.543 mExplanation:
Given:
runner is launched at 30° angle to horizontal at 11 m/s
acceleration due to gravity is g = -9.8 m/s²
Find:
runner's hang time
runner's distance to the landing point
runner's maximum height
Solution:
The (horizontal, vertical) speed components will be ...
(11 m/s)(cos(30°), sin(30°)) = (5.5√3 m/s, 5.5 m/s)
The time of flight can be found from the height formula:
h(t) = 1/2gt² +vt . . . . . . where v is the vertical speed at launch
The time we're concerned with is the time when h(t)=0 and t>0.
0 = -4.9t^2 +5.5√3t = t(-4.9t +5.5√3)
The second factor is zero when ...
t = (5.5√3)/4.9 ≈ 1.122 . . . seconds hang time
__
The distance to the landing point will be the product of horizontal speed and hang time:
d = (5.5 m/s)(5.5√3/4.9 s) ≈ 10.693 m . . . . distance to landing
__
The maximum height can be found from the formula (based on conversion of kinetic energy to potential energy) ...
h = v²/|2g| = (5.5 m/s)²/(2(9.8 m/s²)) ≈ 1.543 m . . . . maximum height
If something is 12 grams and has a volume of 1.6 cubic centimeters, how many grams per cubic centimeter.
Answer: 7.5 grams per cubic centimeter.
Explanation:
We area given that , Mass of something is 12 grams
Volume of that thing is 1.6 cubic centimeters
To find gram per cubic centimeters, we will divide Mass by Volume ( which computes Density)
Number of gram per cubic centimeters = [tex]\dfrac{12}{1.6}[/tex]
Number of gram per cubic centimeters = 7.5
Therefore, 7.5 grams per cubic centimeter. (density of the thing)
