Answer:
I reckon it's part D.
Explanation:
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.

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.

Is there just one universal scientific method?
Answer:
There is no such unique standard method—scientific progress requires many methods—but students in introductory science courses are taught that `The Scientific Method' is a straightforward procedure, involving testing hypotheses derived from theories in order to test those theories.
Explanation:
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.

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.

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).
Type 2 diabetes (insulin-independent diabetes) is a non-infectious disease. If not treated this disease is characterised by large fluctuations in the concentration of glucose in the blood Maltase is an enzyme that completes the digestion of starch in humans Molecules of maltase are bound to the microvilli of epithelial cells in the small intestine Ascorbate is a drug used in the treatment of type 2 diabetes. Molecules of ascorbic have a very similar shape to that of the substrate for maltase. (1) Explain how ascorbase acts to inhibit these membrane-bound enzymes.
Answer: Ascorbase a form of ascorbate, a drug used in the treatment of type 2 diabetes which acts to inhibit maltase a membrane bound enzyme that completes the digestion of starch in the human body.this inhibition is done through;
- By preventing substrates from binding to the active site therefore forming few enzyme complex substrates.
- it also inhibits the enzymes by binding to the active sites of that enzyme.
- it also does so by reacting slowly and also because it has a complementary shape to the active site of the enzyme maltase.

In CaF2, the oxidation number of Ca is , and that of F is . In H2SO4, the oxidation number of H is , that of S is , and that of O is . In CaSO4, the oxidation number of Ca is , that of S is , and that of O is . In HF, the oxidation number of H is , and that of F is
Answer:
1. The oxidation number of Ca is 2, F is -1 in CaF₂
2. The oxidation number of H is 2, S is 6, O is -8 in H₂SO₄
3. The oxidation number of Ca is 2, S is 6, O is -8 in CaSO₄
4. The oxidation number of H is 1, F is -1 in HF
Explanation:
To get the oxidation number, we need to take the oxidation number of the whole compound 0. Then we need to know the oxidation number of the other elements and we need to take 'x' as the oxidation number of the unknown element.
Example:
In case of CaSO₄,
We can write an equation as-
CaSO₄ = 0
If we need to know the oxidation number of S
We can write the equation like this-
→2+ x+ (-2*4) = 0 (as we know the oxidation number of Ca is 2 as it has two electrons in its last shell which it gives to other elements to form bonds and the oxidation number of O is -2 as it takes 2 electrons to complete its outer shell)
→2+ x+ (-8) = 0
→2+ x- 8 = 0
→x- 6 = 0
→x = 6; which is the oxidation number of S
The following are the oxidation numbers:
In CaF2, the oxidation number of Ca is +2, and that of F is -1.
In H2SO4, the oxidation number of H is +1, that of S is +6, and that of O is -2.
In CaSO4, the oxidation number of Ca is +2, that of S is +6, and that of O is -2.
In HF, the oxidation number of H is +1, and that of F is -1.
What is oxidation number?Oxidation numbers are a way of representing the degree of oxidation (loss of electrons) or reduction (gain of electrons) of an element in a chemical compound. The oxidation number of an element is calculated based on the number of valence electrons (electrons in the outermost energy level of an atom) and the rules for assigning oxidation numbers.
In general, the oxidation number of an element is equal to the charge it would have if all the bonds in the compound were ionic (made up of positive and negative ions). This allows chemists to predict the behavior of elements in a compound and to balance chemical equations.

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.

Earth is heated by global warming how Ian the water cycle affected global warming
Answer:
The heat increases the rat of the water making it easier for the water to turn onto vapor
Explanation:
Answer:
[tex]\boxed{\mathrm{view \: explanation}}[/tex]
Explanation:
As the global temperatures increases, more evaporation and precipitation will be the result. Hence, speeding up the water cycle.
At higher temperatures, there is more evaporation from land and sea into the atmosphere. Since the air gets warmer, it can hold more water vapor, this can lead to high rainstorms or precipitation.
