Answer: C. Miller and Urey showed that inorganic compounds could combine to form the building blocks of living cells.
Explanation:
The Miller and Urey were the two scientists who created the atmospheric conditions that were expected to be present on primitive earth. They demonstrated that several organic compounds have been formed spontaneously from the inorganic compounds like water, ammonia, methane and others.
The exposure of mixture of inorganic compounds by the lightening lead to the formation of organic molecules like amino acids which are the building blocks of life. This was similar to the penetration of earth atmosphere by UV radiation producing the organic compounds from inorganic molecules.
Answer:
The correct answer is - glucose is broken down into cellular energy (ATP).
Explanation:
Mitochondria is the double membrane cell organelle presents in all eukaryotic cells that produce the energy by the process of cellular respiration from the food to the cell to perform its day to day functions.
The cellular respiration is the process that involves the braking of the sugars into simple molecules and these catabolic reaction produce energy with CO2 and water as waste. The energy is stored in the form of ATP which is generated in the inner membrane of mitochondria. ATP is used by the cell to perform its function.
Thus, the prower house of the cell is mitochondria.
Answer:
A
Explanation:
The DNA is made 4 nitrogenous bases. A (adenine) pairs with T (thymine) and are held by two hydrogen bonds. C (cytosine) pairs with G (guanine) and are held by three hydrogen bonds.
You might wanna remember this by the preposition 'at', which ultimately makes C and G together. Or you might wanna remember it by something like G- C<em>AT</em>.
Answer:
Conditioned response.
Explanation:
Conditioned response may be defined as a type of learned behavior used in the Pavlov experiment. This type of response mainly generated when the neutral stimulus get mixed with the strong stimulus.
The male quail can be sexually arouse by red light. The red light here acts as the conditioned response because the neutral stimulus (red light) when mixed with the unconditioned stimulus result in the presentation of the female quail and increases the response of the male quail.
Thus, the correct answer is conditioned response.
Answer:
During prophase, chromosomes condense and exit the nuclear envelope to align during metaphase. Anaphase follows metaphase, and is characterized by the separation of sister chromatids. Telophase is the final mitotic stage, during which the cell prepares for cytokinesis.

You're not supposed to give out the answer but thanks anyway
