Answer:
B. He has no E alleles.
Explanation:
In order for the boy to have an attached earlobes phenotype, he must have no E alleles, because the E is dominant. So his genotype must be ee. If he has even just a single E allele (like Ee) he will have detached earlobes, because the dominant trait will mask the expression of the recessive trait.
Why not A or D: Heterozygous Ee (one of each allele) would result in detached earlobes.
Why not C: If he has no recessive alleles, EE, he would have detached earlobes.
Answer:
The forest is defined as a carbon sink, and with its removal, there will be more carbon
released into the atmosphere.

Answer:
1. meiosis 2. meiosis 3. meiosis 4. Binary fission 5. mitosis and meiosis 6. mitosis 7. meiosis 8. mitosis and meiosis 9. mitosis 10. Binary fission 11. meiosis.
Explanation:
The process of mitosis ad meiosis is a type of cell division that occurs in eukaryotes. The type of cell division in prokaryotes including bacteria is the binary division in that they do not have nucleus.
Mitosis is a type of division that produces identical diploid cells as the parent diploid cell. It involves only one division and involved in replacement of damaged tissue and for growth and development.
Meiosis is a type of cell division that produces unique daughter cells with genetic variation as a result of genetic recombination that occurs in the crossing over event in the interphase 1 of meiosis. This type of division involves two division (meiosis II and II) and also produces haploid cells. The parent cell is a germ line cell that was first diploid and then undergoes this form division producing haploid cells to be transferred to offspring.
Answer
Most of these techniques, including microarray analysis and reverse transcription polymerase chain reaction (RT-PCR), work by measuring mRNA levels. However, researchers can also analyze gene expression by directly measuring protein levels with a technique known as a Western blot.
A. Tetanus does not refer to the shape of a bacterium.
