A cinder cone<span> or </span>scoria cone<span> is a steep </span>conical hill<span> of loose </span>pyroclastic<span> fragments, such as either volcanic clinkers, cinders, volcanic ash, or </span>scoria<span> that has been built around a </span>volcanic vent.[1][2]<span> They consist of loose pyroclastic debris formed by explosive eruptions or lava fountains from a single, typically cylindrical, vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as either cinders, clinkers, or scoria around the vent to form a cone that often is beautifully symmetrical; with slopes between 30-40°; and a nearly circular ground plan. Most cinder cones have a bowl-shaped </span>crater<span> at the summit.</span><span>[1]
hope this helps hope i am brainliest i need one more </span>
Answer:
Prokaryotes such as bacteria propagate by binary fission. ... In bacterial cells, the genome consists of a single, circular DNA chromosome; therefore, the process of cell division is simplified. Mitosis is unnecessary because there is no nucleus or multiple chromosomes. This type of cell division is called binary fission.

Answer:
D. GGACCGTCGATCCTT
Explanation:
Mutation refers to any change in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. According to the question, an INVERSION mutation is a type of mutation in which a segment of a gene gets broken off and reattached in another way on the same DNA. Hence, the only change in inversion mutation is the arrangement of the nucleotide bases on the gene.
Considering the nucleotide sequence: GGACCGTCGATCTTC, the sequence that describes an occurrence of inversion mutation is: GGACCGTCGATCCTT because the segment TTC in the original sequence has been rearranged as CTT in the mutated sequence.
Answer: The person is heterozygous for the trait. The person is a carrier of the recessive allele of the trait.
Explanation: Take for instance the height trait. If H is a dominant allele for tall height and h is recessive allele for short height, a person who has one recessive allele and one dominant allele will have a genotype of Hh, this means that the person is heterozygous for the trait. In this example, the genotype Hh will manifest outwardly as tall height because H is dominant over h.
