A biological community of interacting organisms and their physical environment.
Answer:
a. one allele from each parent
Explanation:
According to Mendel, gametes are always pure and contain one allele for each gene. Let's assume that the genotype of the tall plant is "TT" and the genotype of the short plant is "tt". The tall plant would produce all the gametes with one copy of the "T" allele while all the gametes from the short plant would carry only the "t" allele.
The random fusion of gametes from tall and short parent plant produces all the F1 progeny with genotype "Tt". Here, each F1 plant obtained one "T" allele from the tall parent plant and one "t" allele from the short parent plant.
With the choices given, the answer to the biology question presented above would be b. heavy metals such as mercury. Heavy metals contribute to soil pollution more than air pollution. The other choices are sources of air pollution. Thus, letter b is the answer.
Alfred Wegener is often credited as the father of the tectonic playe theory. He got this title when he noticed that the eastern coast of South America and the western coast of Africa appear to fit well together like a puzzle. He used fossil and rock samples from both continents to prove his claim
Answer: it is C
Explanation: Telophase include a reappearance and enlargement of the nucleolus, enlargement of the daughter nuclei to their interphase size, decompensation of the chromatin resulting in a brighter appearance of the nuclei with phase-contrast optics, and a period of rapid
