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 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.

Hope This Helps You ❤️Four differences between the aorta and vena cava ?
Answer:
Aorta and vena cava are two main types of blood vessels attached to the heart. The main difference between aorta and vena cava is that aorta carries oxygenated blood whereas vena cava carries deoxygenated blood. Aorta is the main artery that leaves the heart through the left ventricle. It supplies oxygenated blood throughout the body. Two types of venae cavae supply blood to the right atrium of the heart. They are superior vena cava and inferior vena cava. Superior vena cava drains deoxygenated blood from the head, arms, and other upper parts of the body while inferior vena cava drains that from the lower parts of the body.

Explanation:
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.

Answer:
Cell
Explanation:
Sodium and potassium ions are essential for muscle contractions of the heart, and the ions are transported using a pump, which obtains energy from the breaking of ATP molecules, this action requires the expenditure of energy, so sodium and potassium ions are transported using active transport.
What is muscle contraction?Sodium and potassium ions play a crucial role in muscle contractions, including those of the heart, and to maintain the appropriate concentration of these ions inside and outside the cell, the body uses a protein pump called the sodium-potassium pump, which is an active pump. It requires energy to move substances across cell membranes; the pump uses the energy released by the breakdown of ATP molecules to change its shape, transport the sodium and potassium ions across the membrane, and regulate the muscle contraction.
Hence, the ions are transported using a pump, which obtains energy from the breaking of ATP molecules, this action requires the expenditure of energy, so sodium and potassium ions are transported using active transport.

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

I need to know what which weathering it is
Answer:
the answer is D
Explanation:
Rocks break down into smaller pieces through weathering. Rocks and sediment grinding against each other wear away surfaces. This type of weathering is called abrasion, and it happens as wind and water rush over rocks. The rocks become smoother as rough and jagged edges break off.
i) Describe the function of stomata.
Answer:
Stomata have two main functions, namely they allow for gas exchange acting as an entryway for carbon dioxide (CO2) and releasing the Oxygen (O2) that we breath. The other main function is regulating water movement through transpiration.
Explanation:
the main fiction of stomata is to open and close the pores in the leaves for an exchange of gases.
it allows the plants to take in carbondioxide and gives out oxygen for photosynthesis.
