Answer:
Two essential molecules found in all organisms and that require nitrogen to make them are DNA and proteins (options B and D).
Explanation:
Nitrogen is the most abundant element in the atmosphere and is important for the construction of some organic molecules.
Both nitrogenous bases and amino acids have nitrogen in their molecular structure, and they serve for the constitution of nucleic acids, such as DNA, and proteins.
The process of incorporating nitrogen into living organisms begins with the nitrogen-fixing bacteria found in the soil, which are absorbed by plants and then consumed by animals.
Other options are not correct because both carbohydrates and fats have a predominant composition of carbon, hydrogen and oxygen.

What will happen to the concentration of ATP, NADPH, and sugar when you increase the temperature. Will they decrease, increase, or stay the same?
Answer:
Hello!What happens with ATP, NADPH, and sugar when you increase the temperature is that the mixture will INCREASE.
Explanation:
Hope this helps! :)-jade
The concentration of ATP, NADPH, and sugar will increase if temperature increases.
The rate of photosynthesis is depends upon several factors such as Light intensity and Temperature.
In very low temperature the rate of photosynthesis decreases because some enzymes will not able to work at very low temperatures.At very high temperature the rate of photosynthesis decreases because, enzymes denatured and become unable to work.If the temperature is increased slightly, the the rate of photosynthesis will increase because the enzymes become more active.Therefore, the concentration of ATP, NADPH, and sugar will increase if temperature increases.

Explain how entropy relates to the amount of energy that is available in the different trophic levels of a food chain
Answer:
There ya go!!
Explanation:
Entropy is defined as the measure of heat that is available in any kind of system. When moving towards the next levels in the food chain, the distribution of heat will be less at each stage and at the lower levels of food chain the heat energy that is produced will be high and the value of entropy will be less.
Answer:
Entropy is the tendency of a system towards a larger number of random arrangements. Overall, entropy must increase during processes, so a system will tend towards greater disorder. The energy available for organisms decreases from one trophic level to another, because some of the energy is dissipated as heat from each level to the next because of that tendency toward disorder.

What are the four bases found in DNA and RNA?
Answer:
Nucleic Acids: DNA and RNA
Four different types of nitrogenous bases are found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G).
Answer:
Nucleic Acids: DNA and RNA
Four different types of nitrogenous bases are found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G).
Explanation:The four bases that make up this code are adenine (A), thymine (T), guanine (G) and cytosine (C). Bases pair off together in a double helix structure, these pairs being A and T, and C and G. RNA doesn't contain thymine bases, replacing them with uracil bases (U), which pair to adenine1

Bacteria attach to the roots of pea plants. These bacteria feed off nutrients of the plant and convert nitrogen to ammonia. The plants then use the ammonia for its healthy growth. Which best describes the relationship between these two organisms?
Answer:
Symbiotic relationship
Explanation:
A symbiotic relationship is a relationship between two species that benefit at least one of them. There are 3 different types of symbiotic relationship parasitism (just one benefits while the other is harmed), commensalism (one benefits, the other remained neutral or unharmed) and mutualism (both benefit).
These bacteria feed off the nutrients of the plant and convert nitrogen to ammonia. The plants then use ammonia for healthy growth.
What is the symbiotic relationship between plants and bacteria?Certain plants establish a symbiotic relationship with bacteria, enabling them to produce nodules that facilitate the conversion of atmospheric nitrogen to ammonia. In this connection, cytokinins have been found to play a role in the development of root fixing nodules.
Thus, bacteria feed off the nutrients of the plant and convert nitrogen to ammonia. The plants then use ammonia for healthy growth.

What is unique about stem cells?(1 point)
They are only found in plants.
They are unspecialized.
They are differentiated.
They are only found in embryos.
Answer:
The answer is that they are unspecialized.
Explanation:
Stem cells can turn into multiple different cell types, therefore they have no specific cell that they will become. They are unique because they can turn into many different cells. (Example being one turning into a tissue cell while another turns into a cell for the lungs)
Stem cells are UNSPECIALIZED cells, which are capable of self-renewing in order to create functional tissues.
Stem cells are body cells that have the ability to generate new cell types.Conversely, mature cells (e.g., mature red blood cells) are specialized to play a specific role (e.g. red blood cells transport oxygen).Embryonic stem cells are found in embryos, while adult stem cells are localized in the bone marrow of adults.Embryonic stem cells are pluripotent, thereby they differentiate into different cell types.In conclusion, stem cells are UNSPECIALIZED cells, which are capable of self-renewing in order to create functional tissues.

What parts of the animal do you think were removed to make bath sponges a marketable product?
Answer:
The natural sponges we use in our baths are actually animal skeletons. Bath sponges consist of a highly porous network of fibres made from a collagen protein called spongin. The skeletons are obtained by cutting the growing sponges and soaking the cut portions in water until the flesh rots away. The exposed network of spongin fibres is cleaned and bleached. In recent years New Zealand scientists have investigated the possibility of farming a native species of bath sponge, Spongia manipulatus, for commercial production. Sea sponges have been over-harvested from the major sponge-gathering areas around the Mediterranean, Caribbean and Florida coasts, but demand remains high. Pictured here are two New Zealand bath sponge skeletons, bleached and unbleached.
