Which of the following is released during cellular respiration?
A. Carbon dioxide
B. Glucose
C. Mitochondria
D. Oxygen
Answer:
A.) Carbon Dioxide
Explanation:
The main purpose of cellular respiration is to produce ATP. However, one of the byproducts is carbon dioxide. We use the process of cellular respiration when we take in oxygen (so oxygen isn't the answer) and breathe out CO2. Cellular respiration takes place in the mitochondria, but that's not what's released.
Hope this helps!

Carbon Dioxide

C. It makes it easier to sort out all of
the organisms
D. There were too many bacteria for

Prokaryotes were split into two kingdoms because they were discovered to be very different from each other.
The correct option is B.
What are prokaryptes?Any organism that lacks internal membranes, which prevents the formation of a distinct nucleus and other organelles, is referred to as a prokaryote (also written procaryote). The most well-known prokaryotic species are bacteria. Prokaryotes are different from eukaryotes because they don't have internal walls.
Separate prokaryotic kingdoms with purportedly distinct evolutionary histories are called bacteria or eubacteria and archaebacteria or archaea.

The models below represent nuclear reactions. The atoms on the left of the equal sign are present before the reaction, and the atoms on the right of the equal sign are produced after the reaction. Model 1: Atom 1 + Atom 2 = Atom 3 + energy Model 2: Atom 4 = Atom 5 + Atom 6 + energy Which of these statements is most likely correct about the two models? Both models show reactions which produce energy in the sun. Both models show reactions which use up energy in the sun. Model 1 shows reactions in the nuclear power plants and Model 2 shows reactions in the sun. Model 1 shows reactions in the sun and Model 2 shows reactions in a nuclear power plant.
Answer:There are two kind of nuclear ractions: fusion and fission reactions.
Both release a huge amount of energy in different ways.
Fusion reactions are nuclear reations in which two smaller (lighter) atoms combine into a larger (heavier) atom, with the respective release of energy.
That is what model 1 shows:
Model 1: Atom 1 + Atom 2 = Atom 3 + energy
That is the process that happens and is responsible for the huge amount of heat produced in and released by the Sun.
In the Sun two atoms of hydrogen fuse into a larger atom of helium.
That is represented by the nuclear reaction:

Evan's playroom is 4 m by 3 m. The area of the room is:
o 7 m
07 m2
O 12 m
O 12 m2
Answer:
12 m^2
Explanation:
Area = length * width
A = 4m * 3m
A = 12 m^2
(Area is measured in square units)
Answer:
D. 12 m2
Explanation:
To do this problem, you need to find the area. To find the area of a rectangle, you multiply length x width. In this scenario:
4 x 3 = 12.
So, we know that the first two options are incorrect. Next, we have to look at the unit of measurement that we are needed to imply. In this case, we are using meters, which we need to square. Therefore, the answer is 12 m2.

You are touring several ecosystems, including an icy coastline in the Arctic, and a dry desert in the southwest United States. Do you predict that you will observe equal numbers of ectotherms and endotherms in all ecosystems? Explain your prediction.
Answer:
No.
Explanation:
No, we observe different number of ectotherms and endotherms in Arctic, and a dry desert ecosystems because there is difference in the temperature of both the environment. Due to difference in temperature of the external environment, the number of ectotherms and endotherms are present in that ecosystem. More number of ectoderms are present in the desert ecosystem where the ectoderms survive better than endotherms so we can say that number or population is different.

URGENT !!!!!
Please answer correctly
Answer:
A) Identify the Dependent and Independent variables
The Independent variable is Temperature.
The Dependent variable is the seeds. The dependent variable is the variable that is being studied.
B) Calculate the average height of the seedlings in tube C.
To find the average, you must add up all of the heights and divide by the number of seedlings.
3.4 + 4.5 + 2.5 + 3.7 + 2.8 + 4.4 + 4.3 + 2.9 + 2.1 + 3.7 = 34.3
34.3 ÷ 10 = 3.43 cm
C) Conclusion
The seedlings in tube C grew much taller than the seedlings in tubes A and B.
This means that seedlings germinate better in warmer temperatures.
D) Why does Temperature affect Germination?
The temperature of the climate affects the dampness of the cotton wool. Moisture is key to germinating seeds. Seeds like a moist but not soggy environment caused by the correct temperature.
E) How could the experiment be better controlled?
The light levels in this experiment varied, but were not accounted for in the calculations.
It would have been better to keep them all under the same amount of light in order to keep the experiment accurate.

cuáles son las características adaptativas que favorecen la sobrevivencia de los pingüinos?
Answer:
Los pingüinos tienen una cola corta y rígida. Pueden inclinarse hacia atrás y mantener el equilibrio sobre los talones y la cola. Esto reduce la pérdida de calor de los pies al suelo. El color del cuerpo de un pingüino ayuda a camuflarlo cuando nada.

Penguins have a short stiff tail. They can lean backwards and balance on their heels and their tail. This reduces heat loss from their feet to the ground. The color of a penguin's body helps to camouflage it when it is swimming.
Which of the following statements is true about nitrogen fixation?
a. It is done only by plants.
b. It is done mostly by bacteria.
c. It is how animals make proteins.
d. It is a form of decomposition.
Explanation:
option B is the correct one as it is done by nitrogen fixing bacteria.
It is absorbed by bacteria from the atmosphere as a gas and released to the soil, mostly as ammonia. Thus, option B is correct.
What is role of bacteria in nitrogen fixation?The purpose of nitrogen-fixing bacteria is to provide plants with a crucial nutrient that they are unable to receive naturally from the air. Microorganisms that fix nitrogen can obtain assimilate N for plants in a way that crops cannot.
More than 90% of all nitrogen is fixed by nitrogen-fixing bacteria, which makes them crucial players in the nitrogen cycle.
The majority of nitrogen fixation is done spontaneously by bacteria in the soil. In the soil, nitrogen is fixed and changed in form.
Some bacteria form symbiotic relationships with plant roots that are advantageous to both the plant and the bacteria.
Therefore, It is done mostly by bacteria.
