Answer:
Propose an explanation for why populations of top carnivores, such as hawks, are always smaller than the populations of herbivores, such as caterpillars. Because only ~10% of the energy gets transferred up the pyramid, it takes a lot of the previous level to sustain the next higher level.

If a gap in the fossil record exists between ancient and modern forms of a species, which of the following is the most appropriate conclusion?
A. The gap indicates that gradualism must have occurred for the species to evolve from ancient to the modern form.
B. The gap indicates that punctuated equilibrium must have occurred for the species to evolve from the ancient to the modern form.
C. No conclusions can be drawn because fossils connecting the ancient and modern forms may exist but have not yet been discovered.
D. With no fossils to show connection between the ancient and modern forms, evolution has been disproven.

How does potential energy transfer to kinetic energy?
Answer:
An object has potential energy (stored energy) when it is not in motion. Once a force has been applied or it begins to move the potential energy changes to kinetic energy (energy of motion). Hope this Helps :)

1. Why would cells in some organs be consuming more oxygen than cells in other organs?
2. What happens to the glucose levels in the blood after a meal? Why does this happen?
3. Why might our muscles “burn” when we exercise for long periods of time?
Answer:
1- Im not sure, im so sorry! I hope i could help, if I have the answer ill edit this :)
2- When you eat some form of carbohydrate, the body breaks it down into glucose, such as pasta, fruit, bread or sugar. Glucose is absorbed into the bloodstream and, to be used for energy, insulin helps extract it from your blood into your cells.
3- The breakdown of molecules for energy occurs in the muscle region as people work out, which is why people may feel their muscles burning at the end of a difficult workout.
Explanation:
Intro:
Hello!!! Princess Sakura here ^^
Explanation:
1.) Every cell in your body needs oxygen for cellular respiration. Cellular respiration uses oxygen to break down sugar and create energy. The mitochondria are organelles that produce ATP and usually the muscle cells need the most because they are always working.
2.) The carbs you consume converts to blood sugar. So the more carbs you ingest the higher the levels of glucose you'll have released.
3.) It's because as we workout the breakout of molecules for energy happens in the muscle area, and that's because muscles have the most energy and needs the most energy.

At MOST 500
I use Edmentum an I got it right.
The correct answer is option A i.e. at least 500million years ago.
what are fossils?
Fossils are the preserved remains of plants and animals whose bodies were buried in sediments, such as sand and mud, under ancient seas, lakes and rivers. Fossils also include any preserved trace of life that is typically more than 10 000 years old.
There are five types of fossils:
Body FossilsMolecular FossilsTrace FossilsCarbon FossilsPseudo fossilsso, this trilobite existed around 500 million years ago and million years ago.it is confirmed that the rock might have been formed way before the trilobite fossil that has been formed. It is needed not that the rock has formed during the formation of fossil itself. So we can safely say that the rock is at least 500 million years ago.

It’s never a good idea to Water house plant with salty water plants would most likely die depending on how much of the solution is used how would salt water most likely affect plant cells
Answer:
Water would leave the large vacuole of the
cell and the plant will droop.
Explanation:
Water goes to high to low concentration and water wants to equalize. because there’s more water outside of the plant than inside of the plant so the water will leave meaning that the plant will droop.
If a DNA molecule consists of 29% Adenine, how much Thymine will it contain?
Answer: 29%
Explanation: Remember the base pairing rules: adenine always pairs with thymine (in DNA exclusively; in RNA, where there is no thymine, it will pair with uracil), and cytosine with guanine. Because the nitrogenous bases are always paired rationally, they will always be equal in amount.
How long are X- ray wavelengths compared with ultraviolet wavelengths?

why do cells need to be small?
Cells are small because they need to keep a surface area to volume ratio that allows for adequate intake of nutrients while being able to excrete the cells waste. That is why the cell needs to be small. The smaller it is, the larger the surface area to volume ratio is. ... This is why cells are so small

Meteorologists want to design a system of instruments that will evaluate ocean air temperature and wind speed in order to predict catastrophic weather such as hurricane and cyclones what should they do before producing their first working system of instruments
Answer:
Build a prototype
Explanation:
A prototype may be defined as an early sample or a model or the release of the product that is built to test the concept or the process. It is generally made in use to evaluate some new design such as to enhance the precision by a system analysts and the users.
Thus in the context, a Meteorologists who wishes to design an instrument to evaluate the air temperature of the ocean and the speed of the wind so as to predict hurricanes and cyclones should first built a prototype of his concept and test the process before the production of the first working system.
In dogs, curly tails are dominant over straight tails. If a pure curly-tailed dog is mated with a straight-tailed
dog, what percentage of their offspring will have curly tails?
Answer:
75%
Explanation:
If the two genes were equally dominant then the answer would be 50% because you have a 50/50 chance of getting a curly tailed dog. But since the curly tail gene is more dominant, the answer would have to be 75% because you are more likely to get a curly tailed dog.

Why is meiosis important for organism
Answer:
Meiosis is called as reduction division and it gives rise to four daughter cells which have only half of the genetic information that was present in the parent cell. Hence, it plays very important role in the formation of gametes (egg and sperm). The gametes are essential in the production of zygote which ultimately develops into a new organism.
