Answers
Answer:
A=5
B=9
C=3
D=4
Explanation:
3+2=A, so A must equal 5.
A+4=B, since we know A equals 5 then 5+4=B, therefore B must equal 9.
2+C=5, then use algebra to solve by subtracting 2 from both sides. C=3.
3+1=D, so D must equal 4.

Water lilies grow in freshwater ecosystems. When a water lily plant is kept in seawater, it wilts. Which statement best describes what happens to the water lily plants in seawater?
a.Water moves out of the cells of the lily by osmosis
b.Water moves into the cells of lily by osmosis
c.The cells of water lily plants get less oxygen from the seawater
d.The cells of water lily plants lose all important nutrients to the seawater
IN A TEST RN!!!!
Answers
explanation: osmosis is a process where water moves from a less concentrated solution to a more concentrated one. seawater has more salt than the water inside the lily plant, so this causes the water from inside the plant to move out. without much water inside, the plant begins to wilt.

The impact this would have on the biodiversity of the ecosystems within the Great Barrier Reef is that knowing its takes million of years for coral reef to develop it would be devastating as a end result because many organisms and sea lifes rely on the Great Barrier Reef for survival.

According to Chargaff's rule, base pairing in DNA should resemble which of the following?
A = T; C = G
A = C; T = G
A = G; T = U
A = U; C = G
Answers
The Char gaff rule is all about the number of adenine is equal to the number of thymine and with that the number of cytosine is equal to the number of guanine. The correct answer is option B.
What are the types of bonds that are present in between these nitrogenous bases ?The kind of bonds that are present in these nitrogenous bases are hydrogen bonds. A binds with T with two hydrogen bonds and C binds with G through 3 hydrogen bonds.
It is all about that the number of purines is equal to the number of pyrimidines. The number of adenine molecule are present totally in equivalence to the number of thymine molecules.
The number of guanine molecules are present in the molecule of DNA are totally in numbers to the cytosine. In place of thymine uracil is present which is present in RNA.
Therefore, The Char gaff rule is all about the number of adenine is equal to the number ofThe Char gaff rule is all about the number of adenine is equal to the number of thymine and with that the number of cytosine is equal to the number of guanine. The correct answer is option B.

9. What does a pyramid of energy show about the amount of energy available at different trophic levels of a food chain?
10. Why do different trophic levels have different amounts of energy?
Answers
Answer:
A food web can be formed by more than one food chain, since the webs includes all possible interactions that can occur between individuals of different trophic levels.
Explanation:
Based on the scheme shown in the image
1. How many food chains make up the food web?This food network is made up of three food chains
Plant → Bird → SnakePlant → Insect → Bird → SnakePlant → insect → Frog → SnakeFood webs often include several food chains, since they are due to the interaction between organisms at different trophic levels, which actually happens within an ecosystem.
2. Which organism is an herbivore?In this case, both the insect and the bird are herbivorous organisms, since they feed of the producer, which is the plant.
3. Which organism is an autotroph?The only autotrophic organism is the plant, since it is capable of manufacturing its nutrients from sunlight and inorganic matter.
4. Which organism is a third-order heterotroph? To what trophic level does that organism belong?The third order heterotroph is the snake, since it feeds on other animals. The snake is a carnivore and can be a secondary or more commonly tertiary consumer, so it can be placed in the 3rd or 4th trophic level.
5. Which organism is an omnivore?According to the scheme proposed, the bird is omnivorous, since it feeds on both plants and insects.
6. Which organisms belong to more than one food chain?In this case, the plant, the insect, the bird and the snake are part of more than one food chain.
Plant → Bird → SnakePlant → Insect → Bird → SnakePlant → insect → Frog → Snake 7. Which organism belongs to more than one trophic level?The bird can be located in both the second and third trophic level, being a primary consumer —when it feeds on plants— or secondary, when it feeds on insects.
8. What are decomposers? From which trophic levels are the organisms that decomposers feed on?Decomposers are generally bacteria and fungi, organisms capable of degrading organic matter, thus enriching the soil. Decomposers can feed on any trophic level.
9. What does a pyramid of energy show about the amount of energy available at different trophic levels of a food chain?As the ascent of the pyramid occurs —or at the upper trophic level— the amount of energy available decreases. This is because from one trophic level to another only 10% of the energy can be used. If a plant has 5000 Kcal available, the herbivore that consumes it can only use 500 Kcal.
10. Why do different trophic levels have different amounts of energy?The main reason for the difference in energy in each trophic level is that energy is lost in each one of them, which the organisms use in their metabolism. A consequence of the metabolism is the loss of energy as heat, which is acquired by the environment.

Change that happens in a living organism because of a stimulus
Answers
Answer: A change in an organism's surroundings that causes the organism to react is called a stimulus (plural stimuli). An organism reacts to a stimulus with a response- an action or change in behavior. Another example is if you are cold, you shiver. The cold is the stimulus while the shivering is the response.
(The plural of stimulus is stimuli. Its verb form is stimulate, which typically means to spur into action or to invigorate.)
