decomposition of what was alive then the remains are buried by sediments which results in fossilization
Answer:
<u><em>The correct options are:</em></u>
<u><em>All traits are inherited.</em></u>
<u><em>Offspring inherit one allele for a gene from each parent.</em></u>
<u><em>An offspring with two identical alleles for a trait is homozygous.</em></u>
Explanation:
- In the biological world, a trait can be described as a genetic characteristic which makes up an organism. Every organism has a particular set of traits.
- Traits are inherited from parents, however they can be influenced by the environment.
- The alleles of a gene make up the genotype and the influencing phenotype. An organism acquires one allele for the gene pair from each parent.
- When both the alleles of a gene pair are similar, the organism is said to be homozygous for the trait. If both the alleles of a gene pair are different, the organism is said to be heterozygous for the trait.
Answer:
B. A helicase enzyme unwinds the DNA molecule, then corresponding nucleotides are added to the separated original strand forming two separate semiconservative molecules
Explanation:
DNA Replication is an important phenomenon as far as cell division is concerned. It is the process whereby a DNA molecule doubles its content or forms two DNA molecules from one.
In the semi-conservative model of DNA replication, an enzyme called DNA helicase unwinds the double stranded DNA molecule into two single strands. The single strands are then used as template for DNA polymerase to synthesize another molecule of DNA. Hence, two separate DNA molecules comprising of one old strand and one new strand.
The correct answer is the marble would weather more rapidly.
The weathering of the rock can be defined as the procedure of the erosion of the rock by various agents. The marble is a metamorphic form of the limestone. The limestone is easily affected by the hot and the humid climates. The rain and the atmospheric carbon dioxide get mix together form mild acids, this acid react with the limestone and causes the chemical changes. As a result, the marble is subjected to erosion in hot and humid climate.
