A woman with type ab blood and a man with type o blood have a child. Which type of blood could the child have?.
Answer: either A or B blood type.
Explanation:
a neuron and a white blood cell have very different functions. for example, a neuron can receive and respond to electrical signals, while a white blood cell defends the body against infection. this is because group of answer choices all of the proteins found in a neuron are completely different from the proteins found in a white blood cell. the neuron and the white blood cell within an individual have the same genome. the neuron expresses some mrnas that the white blood cell does not. neurons and white blood cells are differentiated cells and thus no longer need to transcribe and translate genes.
The blood cells and neurons are wholly separate populations, and the two cell types are not interdependent in any way.
The Correct Answer is : the neuron expresses some mRNAs that the white blood cell does not.
Do white blood cells have RNA?Protein can be produced by white cells that have a nucleus and can create ribonucleic acid (RNA). White blood cells are highly differentiated for their particular functions, so they do not divide into new cells in the bloodstream (mitosis), yet some still have this ability.Leukocytes, thrombocytes, and erythrocytes make up human blood. When determining the amount of nucleic acid in human blood, leukocytes—the only cells with a nucleus—are crucial. While erythrocytes and thrombocytes do contain a small quantity of RNA, they lack a cell nucleus.Here, we report the presence of standard bands for the eukaryotic RNAs 28S and 18S in human RBCs. According to microarray research, erythrocytic RNA contains transcripts from 1019 distinct genes.To Learn more About blood cells and neurons refer to:

What part of the cell cycle has been disrupted to allow for the formation of cancer cells?.
The formation of cancer cells occurs in the interphase cell cycle which is disrupted, precisely when DNA synthesis is in the S phase.
How does the cell cycle affect cancer?In many cancer cells, the number of chromosomes changes so that there are either too many or too few chromosomes in the cell. These cells are said to be aneuploid. Errors can occur during DNA replication resulting in mutations and possible development of cancer.
Cancer is the result of uncontrolled cell division caused by damage to the mechanism that regulates the cell cycle. Loss of control begins with a change in the DNA sequence of a gene that codes for one of the regulatory molecules. Incorrect instructions cause the protein to not work as it should.
Cells that progress through an uncontrolled cell cycle may eventually form a malignant tumor, in which masses of cells grow and divide uncontrollably, then develop the ability to spread and migrate throughout the body.

If pacific field male crickets in hawaii attract females by rubbing their wings together to sing, why is it that in some places up to 90% of the males no longer sing? how could this have evolved?.
The reason why 90% of male crickets no longer sing is Convergent evolution.
What is convergent evolution?It is the independently occurring evolution of traits that are shared by species across historical eras. Analogous structures with similar functions or forms are created as a result of this evolution. They are not present in those units' most recent shared ancestor, though.
Despite the resemblance of the structures, homology is not reflected. Similarity can exist at the phenotypic level, where lineages exhibit identical outward traits yet have different implicit DNA sequences. This kind of evolution occurs when species occupy comparable ecological niches, accommodate similarly, and respond similarly to selective pressures.
