Phenotype, physical appearance, is determined by the genotype, an organism's genetic makeup.
D. would be the most accurate because you can't make waste without developing also you get energy from developing so D would be the correct answer
Answer:
The answer is; Simulation of early Earth conditions and long-term study of the resulting molecules
Explanation:
It is believed that the first molecules on earth were made spontaneously through reaction spurred by energy from lightning and also the heat from the earth. It is believed that these molecules over time then formed polymers through the catalysis by metals in the oceans. These polymers were able to self-replicate and also act as enzymes since they were able to fold up. This hypothesis was coined by Carl Woese, Francis Crick and Leslie Orgel in the 1960s. To prove it, the then conditions of early earth need to be replicated, data collected, and analyzed.

The structural feature of a spermatozoon containing mitochondria arranged in a spiral around the microtubules is the sperm neck. The spermatozoon functions to carry genetic material from the body of a male. It consists of two major parts which are the head and the tail. It is in the tail that the neck is found. This part is a constricted and a short segment. At least two mitochondria can be found in this portion.
