Answer:
B
Explanation:
All substances, whether living or nonliving are made up of atoms. Different combination of these atoms is what forms different molecules, elements, and compounds. An example is that carbon atom, which is the chief atom of life on earth, is also the main component that makes up nonliving substances such as diamond and graphite.
Answer:
crabs, shrimp, starfish, scallops and sea urchins
Explanation:
Unequal crossing over during Prophase I can result in one sister chromosome with a deletion and another with a duplication. A mutated form of hemoglobin, known as hemoglobin Lepore, is known in the human population. Hemoglobin Lepore has a deleted set of amino acids. If it was caused by unequal crossing over, what would be an expected consequence?
A) There should also be persons whose hemoglobin contains two copies of the series of amino acids that is deleted in hemoglobin Lepore.
B) Each of the genes in the hemoglobin gene family must show the same deletion.
C) The deleted gene must have undergone exon shuffling.
D) The deleted region must be located in a different area of the individual's genome.
Answer:
A) There should also be persons whose hemoglobin contains two copies of the series of amino acids that is deleted in hemoglobin Lepore.
Explanation:
The process of crossing over generates recombinant chromatids that carry the exchanged genetic segments. In case of unequal crossing over, a part of the genetic segment is missing from one recombinant chromatid of a homologous chromosome and is inserted into the recombinant chromatid of the corresponding homologous chromosome. The gamete that obtains the chromosome with an additional genetic segment would give rise to a person carrying the duplicated amino acids that are otherwise missing from the chromosome of the person expressing hemoglobin Lepore.
Answer:
genotype; (rr)
phenotype; black eyes
Explanation:
<em>phenotype </em>is the physical characteristic of the individual, which is expressed by the <em>genotype</em>.
<em>genotype </em>is the genetic code of the individual
Answer: France
Explanation:
The French Revolution began in 1789 and was based on the High Enlightenment vision that called for an overthrow of old authorities such as the monarchy, replacing it with a leadership that was more reflective of the will of the people and changing all society to be more rational in operation such that liberty and equality were prominent virtues.
The intentions were good but the execution saw much blood and violence and led to different factions taking control of the Government to lead the French in a manner they thought best. All this ended in 1799 however, when Napoleon Bonaparte took power.
