Given what we know about global carbon levels in the present and the past, we can confirm that in order to be at the level of early civilizations, the modern-day carbon level should be at 280 parts per million.
Global atmospheric carbon levels are measured in parts per million. What this means is that for every one million units of mass in the atmosphere, 280 of them were carbon. This means that in recent years, the global carbon levels in the atmosphere have doubled.
The primary cause of these increased carbon levels is industrial pollution. Chemicals are released into the atmosphere as a by-product of industrial processess. This began with a noticeable spike during the industrial revolution and has then increased without end.

[tex] \huge \bf༆ Answer ༄[/tex]
The acceleration produced by that boy is Zero .
_____________________________________
Want to know how ? here's the reason : -
As he is running with a constant velocity, so there's no change in velocity and Acceleration is defined as " Rate of change in Velocity " and since there's no change in velocity and direction (because he is moving in a straight road) hence Acceleration is 0.

How has the global climate changed in the last century? What has the greatest impact on the climate where you live? Have humans influenced the climate on Earth? If so, how and what should we do?
Answer:
Over the last century, the average temperature on the surface of the Earth has increased by about 1.0 degrees F. The greatest impact is the droughts that my state is constantly in. I believe that we had a great part in global climate change. How I think that we have is all the air pollution and not taking care of out earth the way we should. How I think that we can fix this is if we start powering our home with more solar. We can also reduce the amount of water that we use.
Explanation:

Based on information from the cladogram and the data table shown below, which of the following best describes the evolutionary history of rabbits?
Claws/Nails Feathers Jaws Lungs Mammary glands
Bird X X X X
Hagfish
Lizard X X X
Rabbit X X X X
Salamander X X
Tiger X X X X
Trout X
Image depicts a cladogram with hagfish, trout, salamander, lizard, bird, rabbit, and tiger represented. Trout diverge from hagfish with the introduction of jaws. Salamander diverges from trout with the introduction of lungs. Lizard diverges from salamander with the introduction of claws and nails. Bird diverges from lizard with the introduction of feathers. Rabbit and tiger diverge from lizard with the introduction of mammary glands.
They are more closely related to tigers than they are to birds.
They became able to produce mammary glands as a result of lacking feathers.
They evolved into a separate species due to the presence of mammary glands.
They share a more recent common evolutionary ancestor with salamanders than they do with lizards.
Answer:
A. They are more closely related to tigers than they are to birds.
Explanation:
Short answer: I took the test
Actual explanation:
-If you look at the first graphic that you have, you will notice that rabbits and tigers have all the same boxes checked off. AND birds and rabbits only have 3 checked off.
-salamanders actually have less in common with rabbits than they do with lizards, salamanders have 3 things in common, and lizards only have 2, proving option D. wrong. (if you are wondering where I got that evidence, look at the chart) AND if you look at the cladogram, lizards are closer to the rabbits than salamanders meaning that lizards have a more common ancestor (I think?) But nevertheless, it it still wrong, because of the above evidence.
- The options with mammary glands are also incorrect for these reasons, B. makes no sense, literally no sense, why would not be able to produce mammary glands with feathers, so B, is automatically out. With option C, rabbits did not evolve into a whole new species, it is the clade showing that tigers and rabbits both have mammary glands. There is no showing of a new species on the cladogram, and I don't think that it makes sense to evolve into a whole species just because of mammary glands.
- Now, if you look at the cladogram again, you wills see that tigers and rabbits are closest together, meaning that they are closely related. BUT, birds and rabbits are also the closet together, so, refer back to point a, that the chart shows that birds only share 3 out of the 4 that rabbits and tigers share. so that's that.
So after doing the work, option A. Rabbits are more closely related to tigers than they are birds. (and If you read my long explanation THANK YOU I put time and effort into it to make it accurate :))
Hope this helped :)) ~addison

membrane molecules that use the energy of atp to move ions against a concentration gradient are called
Membrane molecules that use the energy of ATP to move ions against a concentration gradient are called PUMPS. This type of transport is called active transport.
Active transport is a type of transport that requires energy (e.g, ATP) to move molecules and/or ions against a concentration gradient.
In active transport, specific membrane transporter proteins referred to as pumps are used to move ions against an electrochemical gradient across biological membranes.
These protein pumps are fundamental for creating electrochemical gradients that are subsequently used by cells for diverse purposes (e.g., muscle contraction).

Stickleback fish protect themselves from predators with a thick covering of brownish plates. They feed on
small aquatic organisms and are preyed upon by bigger fish like trout. In a certain lake, the number of
stickleback fish was documented over a period of 30 years. During this time, the clarity of the lake water
also changed.

every time the differences will change because of the large fishes which kill the small ones and the fishes het big like in one big fish there will be 100 of small fishes like the megladon
during this blood also leaks and the colour of the lake changes
Answer:
In each instance, the variations in fish populations are subject to change due to the predation of larger fish on smaller ones. As a result, the surviving fish grow larger, akin to the manner in which the Megalodon can have hundreds of smaller fish within its body. This process can also result in the release of blood, which has the potential to alter the color of the surrounding water body.

Explanation:
During exercise, the blood is travelling more quickly around the body. This carries more oxygen to the exercise muscles. Describe other changes in the athlete's body that enable more oxygen to be taken in at the lungs.
Answer:
your heart rate goes up explaining why the blood is traveling quicker. this causes you to breath faster meaning bring more oxygen to the blood in your lungs faster. your blood pressure also goes up from the increase in heart rate.
Answer:
the breathing rate and volume of each breath increases to bring more oxygen into the body
Explanation:
it removes the carbon dioxide produced. the heart rate increases, to supply the muscles with extra oxygen and remove the carbon dioxide produced.

Suppose white and brown fur in a species of rodent were due to different alleles at the same gene. An F1 cross between true breeding brown and white lines is set up. What evidence would best support white fur being dominant to brown
An F1 cross between true breeding brown and white lines is set up. What evidence would best support white fur being dominant to brown -----
The best evidence to show that white fur being dominant is when all the offspring after the cross are white instead of brown
They are therefore expected to produce heterozygous lines.
The evidence that would best support white fur being dominant is when all the lines produced are white despite being heterozygous.
A dominant trait is known to mask the expression of other traits.

please help me with insects with out piercing and sucking mouth parts and the reason why. please help me I really request.
Answer:
Insects have a range of mouthparts, adapted to particular modes of feeding. The earliest insects had chewing mouthparts. Specialization has mostly been for piercing and sucking, although a range of specializations exist, as these modes of feeding have evolved a number of times (for example, mosquitoes and aphids (which are true bugs) both pierce and suck, however female mosquitoes feed on animal blood whereas aphids feed on plant fluids. In this page, the individual mouthparts are introduced for chewing insects. Specializations are generally described thereafter.
