Answer:
This child should receive only a small fraction of the standard dose.
Explanation:
Acute lymphoblastic leukemia may be defined as the cancer in which the bone marrow continuously divide and results in the formation of large number of lymphocytes. This may also effect the red blood cells as well as platelets.
6-mercaptopurine drug is used for the treatment of the acute lymphoblastic leukemia. Since, child does not have enough enzyme for the metabolism of this drug, only the small amount of the standard dose of this drug for the cancer treatment.
Thus, the correct answer is option (b).
Answer:
SAMPLE ANSWER: The model does not represent a compound because it shows two atoms of the same element combined. To be a compound, the model would need to contain atoms of different elements, represented by different-colored balls.
Explanation:
Answer:
Physical science is the study of the inorganic world. That is, it does not study living things.
Explanation:
that would not be possible without phosphorus.
Answer:
It would be impossible to store and transfer genetic information
It would be impossible to carry out majority of cellular activities due to lack of usable energy.
Explanation:
Phosphorus, as stated in the question, represents a very low amount in our body system, however, its role in living systems cannot be underestimated. Phosphorus is a vital component of major biomolecules in our system.
- It is the building block of the NUCLEOTIDES that make up nucleic acids. Nucleic acids (DNA and RNA) store genetic information and help transfer it to offsprings. However, without one of the elemental components (phosphorus) that make up its structure, it will not be produced. Hence, the storage and transfer of genetic information will be impossible.
- Phosphorus also makes up the structure of the ADENOSINE TRIPHOSPHATE (ATP) molecule. ATP provides the cell with all the energy used in carrying out cellular functions. However, the absence of phosphorus needed for the synthesis of ATP, ATP will not be produced and ultimately no energy.
Phosphorus is necessary for DNA, RNA, ATP, phospholipids, enzyme activation, energy metabolism, and pH balance in cells.
Phosphorus is an essential element in the human body and plays a crucial role in various cellular functions. One of the primary functions of phosphorus is its role in the structure and function of DNA, RNA, and ATP (adenosine triphosphate), which are all fundamental to cellular processes. Phosphorus is also involved in the formation of phospholipids, which are the main components of cell membranes.
Furthermore, phosphorus is important for the activation of enzymes, regulation of cellular energy metabolism, and maintaining pH balance within cells. The (ATP) molecule's structure is made up of phosphorus as well. All of the energy required for the cell to perform its cellular processes is provided by ATP. However, because phosphorus is required for the synthesis of ATP, ATP cannot be created, which results in the absence of energy.

B. In maternal effect, an offspring will have the genotype of their mother.
C. In a reciprocal cross, if an offspring has the mother's phenotype for both crosses, cytoplasmic inheritance is responsible.
D. The direction of shell coiling in Lymnaea peregra is influenced by the orientation of the first cleavage division.
E. It is safe to say that a maternal effect is caused by the genotype, not the phenotype, of the parent producing the egg.
Answer:
Answer is D.
Explanation:
The first cleavage division can be explained or described as the series of first cellular division of the zygote after fertilization.
In this case, the process of recoiling of the shell of the snail can not be categorized as one of the examples at this stage.
Answer:
Out of the 22 amino acids, 8 cannot be produced in the body and must be consumed from outside sources, so they're called "essential".
b. Cnidarians
c. Nematodes
d. Insects
e. Vertebrates
Answer:
The correct answer is E. Vertebrates have a closed circulatory system.
Explanation:
The main mission of the circulatory system is to deliver oxygen and nutrients to all body cells.
In the closed circulatory system, blood travels inside a network of blood vessels, without leaving them. The material transported by the blood reaches the tissues through diffusion. It is characteristic of all vertebrates, including humans.
