An 18-month-old boy was referred to the pediatrics clinic because of persistent anemia and associated failure to thrive. Laboratory analysis confirmed a microcytic anemia and revealed blood lead levels of 50 mg/dL (2 times normal levels) and high levels of coproporphyrinogen III in the urine. The child was put on chelation therapy and recovered uneventfully. The cause of the child's difficulty was most likely due to the effects of the lead. The findings in this patient most closely reflect lead inhibition of which of the following enzymes of heme biosynthesis?a) δ-aminolevulinic acid (ALA) dehydrataseb) ferrochelatasec) porphobilinogen (PBG) deaminased) proporphyrinogen III cosynthasee) uroporphyrinogen decarboxylase
Answer:
B) Ferrochelatase
Explanation:
The hematological effects of lead poisoning includes the inhibition of the body's ability to produce hemoglobin. This is done by interfering with several enzymatic steps in the heme synthesis pathway.
Lead inhibits or decreases heme synthesis by inhibiting Ferrochelatase enzyme activity.
Ferrochelatase catalyses the insertion of iron into protoporphyrin IX and is very sensitive to lead.
A 6-month-old who is failing to thrive is brought to your clinic. Tests reveal hepatosplenomegaly, muscle weakness and atrophy, hypotonia, and decreased deep tendon reflexes. Biopsy of the liver reveals initial stages of cirrhosis due to the accumulation of an abnormal glycogen whose structure resembles amylopectin. These results indicate the child is suffering from Andersen disease. Which of the following would also be expected in this child?a) aminoaciduriab) hyperglycemiac) hyperlipidemiad) hypoglycemiae) normal glycemia
Answer:
c) hypoglycemia
Explanation:
Hyperglycemia refers to the condition in which blood contains low amount of sugar or glucose molecules. The feeling of hunger, sweating and weakness of muscles are the symptoms of this disease and we know that the child has weak muscles so we can say that the child is suffering from hypoglycemia which is another disease that is present in the child.

What molecule is required each time the myosin head detaaches from one site and reattaches to another
Answer:
The adenosine triphosphate (ATP) molecule
Explanation:
The actin filaments are often associated with myosin to produce muscle contraction. These myosin filaments are considered to be 'molecular motors' capable of converting the chemical energy contained in the ATP molecule to mechanical energy, thereby producing cell movement. Myosin heads bind to actin filaments in order to generate a power stroke. When the adenosine triphosphate (ATP) molecule binds to myosin, the myosin head detaches to the actin filament. During this process, the ATP molecule is broken down and then the released energy is used by the myosin filament to return to its original position.

Complete question reads;
Read the following paragraph from the article.
In soccer, Hai is a goal scorer who plays in forward positions, always keeping his eyes trained on the ball and chance to put one past a goalkeeper. He’s not above playing advantages. “(Other players) don’t want to hurt me,” he said. “I try to juke them.” His coach said opponents soon learn to play him honestly or pay the consequences.
Which idea is BEST supported by the above paragraph?
(A) Hai's coach recognizes that Hai needs to be protected from bullying.
(B) Hai is a very skilled soccer player who consistently outdoes his peers.
(C) Hai's coach wants Hai to understand that it is not acceptable to cheat to win a soccer game.
(D) Hai is sometimes underestimated by other players, and he uses this to his advantage.
Answer:
(C) Hai's coach wants Hai to understand that it is not acceptable to cheat to win asoccer game.
Explanation:
The expression, "pay the consequences" as used by Hai's coach indicates his intention of letting Hai know the rules governing soccer; meaning there's a penalty when opponents hurt a rival player.
Interestingly, in the game of soccer, it is a foul to deliberately bring down your opponent. Major consequences arrive when a player receives a red card from the referee, due to an offense committed by the player; the red card indicates that the player would be sent out of the court.

Abnormal vascular regulation by endothelial cells in small vessels of the heart contributes to:___________. a. Hypertension b. Dysrhythmias c. Truncus arteriosus d. Ischemic heart disease
Answer: The correct answer to the question is option D
ISCHEMIC HEART DISEASE.
Explanation: To answer the question effectively, let us look at the options given,what they are and how they affect the heart.
Endothelial cells play a crucial role in the regulating vascular tone,They do so by secreting variable amounts of constricting and relaxing factors inorder to control tissue perfusion.
Hypertension on the other hand occurs as a result of factors that varies distinctively and not all related to vascular tone.
Dysrhythmias on it's own will affect the function and conduction of heart chambers but not necessarily vascular tones.
Truncus arteriosus results in only in one large artery exiting/leaving the heart.

what has a greater influence on protien levels
Question is incomplete, The complete question is as follows:
What has a greater influence on protein levels?
A. Protein degradation has a greater influence because they are denatured faster than the cell can produce them
B. mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced
C. mRNA destroyer concentration has a greater influence because mRNA is destroyed right after the proteins are produced
D. Protein degradation has a greater influence because outside factors like antibiotics can cause it, and it is difficult to recover from
Answer:
B. mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced
Explanation:
mRNA destroyer concentration has a greater influence on protein levels because mRNA destroyers abort the mRNA as soon as the enough mRNA are produced before formation of proteins.
mRNA destroyer follow the mRNA around itself and dragged it once mRNA is picked for protein synthesis.
Hence, the correct answer is "B".
What is a scientific theory? What is a hypothesis? How are they similar? How do they differ?
Answer: Scientific theories can be backed up with evidence/data (the evidence that backs the theory isn't common knowledge to everyone yet), while a hypothesis is just an educated guess, meaning that you are making a prediction based on something already known.
They are both similar in the sense that they are questions that are answered by facts, but theories are answered with factual evidence rather than factual reasoning (hypothesis).

Which of the following best characterizes an adaptive radiation? Which of the following best characterizes an adaptive radiation? Natural selection is particularly intense because disruptive selection occurs. A single lineage diversifies rapidly, and descendant species occupy many habitats and ecological roles. Descendant species occupy a large geographic area. Species recover after a mass extinction.
Answer:
A single lineage diversifies rapidly, and descendant species occupy many habitats and ecological roles.
Explanation:
In biology, adaptive radiation refers to a phenomenon in which organisms tend to diversify rapidly from a common ancestor and then radiate into a multitude of new organisms.
These new organisms may have to change their environment in order to survive. This change in their environment creates new challenges and may lead to the appearance of new environmental niches.
