Because the first two statements are true, Eric is the youngest of the three, so the third statement must be false.

D) Heme

CO2 combines with the amino (NH2) groups of the globin chains of hemoglobin, forming carbaminohemoglobin. It does not directly combine with the heme group. The heme group in hemoglobin is responsible for binding oxygen, not carbon dioxide.

B) Mg^2+

Among the given options, Mg^2+ possesses the maximum hydration energy. This is because magnesium ion (Mg^2+) has a high charge density due to its 2+ charge and relatively small size. As a result, it attracts water molecules strongly, leading to a higher hydration energy compared to the other ions listed.

The primary source of energy in lipids comes from the C-H bonds, represented by option C. When these bonds are broken through oxidation, energy is released for cellular processes.

The correct answer is:

C) 45%

P1V1/P2
Putting values, we get 25cm^3

To find the number of moles present in 0.6 grams of silica, we first need to determine the molar mass of silica (SiO2).

The molar mass of silica (SiO2) is calculated as follows:
1 atom of silicon (Si) weighs 28 grams
2 atoms of oxygen (O) weigh 2 * 16 = 32 grams

So, the total molar mass of SiO2 = 28 (Si) + 32 (O) = 60 grams/mol

Now, we can use the formula for calculating the number of moles:

Number of moles = Mass (in grams) / Molar mass

Substituting the given values:
Number of moles = 0.6 grams / 60 grams/mol = 0.01 mol

Therefore, the correct answer is:
A) 0.01 mole

Here are the meanings of the words provided:

(A) Statute: A written law passed by a legislative body. It's a formal enactment of a rule or regulation.

(B) Legislation: The act of making or enacting laws. It refers to the process of creating laws by a legislative body.

(C) Ballot-papers: These are the physical or digital documents used for voting in an election. They contain the names of candidates or options for voters to choose from.

(D) Suffrage: The right to vote in political elections. It's the privilege or franchise of voting, especially in public elections.

B) Displacement of the OH-1 from the acid by OCH3

During the formation of an ester from acetic acid, the reaction involves the displacement of the hydroxyl group (OH-) from the acid (acetic acid) by the methoxy group (OCH3) from the alcohol. This substitution reaction leads to the formation of the ester.

The correct answer is:
B) Coelomates

Option C uses the correct punctuation marks:

A semicolon (;) is used before "otherwise" to join two closely related independent clauses.
A comma (,) is used after "otherwise" to set off the transitional adverb from the rest of the sentence.

A semicolon (;) is used before "otherwise" to join two closely related independent clauses.

A comma (,) is used after "otherwise" to set off the transitional adverb from the rest of the sentence.

Ratio of third mode frequencies for closed pipe to open pipe.

As we know that,

Concepts of :

Open organ pipe (One end open).

Fundamental frequency : fₙ = (nv/2l).

Closed organ pipe (One end closed).

Fundamental frequency : fₙ = (nv/4l).

Using this concepts in this question, we get.

Third mode frequencies for open organ pipe.

⇒ f₃ = (3v/2l).

Third mode frequencies for closed organ pipe.

⇒ f₃ = (3v/4l).

To find : Ratio of third mode frequencies for closed pipe to open pipe.

(Ratio of closed organ pipe)/(Ratio of open organ pipe).

⇒ [(3v/4l)]/[(3v/2l)].

⇒ (3v/4l) x (2l/3v).

⇒ (2/4).

⇒ (1/2).

Correct option is B ThO2

Zinc (Zn) is a metal that can replace hydrogen from dilute acids to form salts. This reaction is a common example of a single displacement reaction in chemistry. When zinc reacts with a dilute acid, such as hydrochloric acid (HCl) or sulfuric acid (H2SO4), it displaces the hydrogen in the acid to form zinc salts and hydrogen gas. This is represented by the general equation:

Zn(s) + 2HCl(aq) -> ZnCl2(aq) + H2(g)

So, the correct answer is option B) Zn.

I appealed to her to look after my children during my absence, and she acceded to my request."

In this sentence, "to" is the appropriate preposition to use after "appealed" and "acceded."

C) Secondary alcohol

When a ketone is reduced using sodium borohydride (NaBH4), it results in the formation of a secondary alcohol. This is because the hydrogen from NaBH4 adds to the carbonyl group of the ketone, leading to the formation of a new hydroxyl (-OH) group, resulting in a secondary alcohol. Phenol is not typically formed through the reduction of a ketone with NaBH4.

The correct answer is D) It generates ATP through oxidative phosphorylation. The pentose phosphate pathway (PPP) produces NADPH and ribose-5-phosphate, contributing to biosynthetic processes and antioxidant defense, but it does not directly generate ATP through oxidative phosphorylation, which occurs in the mitochondria.

Key Points

In the given sentence, the adjective ''too much'' before the adjective 'windy' is incorrect.

The adjective ''too much'' is used before the nouns showing the quantity.

The word 'windy' in the sentence is an adjective.

The adverb ''much too'' is used before adjectives to modify the adjectives.

Therefore, the adverb ''much too'' should be used in place of the adjective ''too much''.

T1=T2
5*50=10* x
250/10=x
x=25cm
Now we have to find OP which is equal to
50cm+ 25cm=75cm

The correct answer is "gave - wouldn't". This is because the sentence is in the conditional form, expressing a hypothetical situation. The verb "gave" is in the past tense, indicating a past action that did not happen. The verb "wouldn't" is the negative form of "would", indicating that if the hypothetical action of giving had occurred, there would be no money left.

Zero order with respect to a reactant Means that the rate of
reaction is Independent of the concentration of the reactant i.e. a change in concentration of P has no effect on the rate of the reaction.

So, the correct answer is:
A) △H = ΔE

The codon for Phenylalanine is:
A) UUU

Here are some examples of common codons:

UUU and UUC both code for the amino acid Phenylalanine.
UUA and UUG both code for the amino acid Leucine.
CUU, CUC, CUA, and CUG all code for the amino acid Leucine as well.
AUU, AUC, and AUA all code for the amino acid Isoleucine.
AUG codes for Methionine and serves as the start codon.
GUU, GUC, GUA, and GUG all code for the amino acid Valine.
These are just a few examples, as there are a total of 64 possible codons, including stop codons.

6 µF and 3 µF are in series

C = 3*6/3+6 = 18/9
C = 2

Both 2µF are also in series

C = 2*2/2+2 = 1

Nor finally
C = 2+1 = 3µF

0 , because Glycolysis produces NADH not NADPH

The most appropriate word to replace "belittle" without changing the meaning of the sentence is "disparage." It maintains the sense of diminishing or downplaying the legitimate concerns of parents. Therefore, the correct answer is:

1. A) disparage

The logical relation between "oasis" and "sand" is that an oasis is surrounded by sand, providing a contrast between water and a dry, desert environment. Following the same logic, the correct option would be something that contrasts with an island, which is surrounded by water. Therefore, the most appropriate option is:

The odd one out is "B) Cilia" because it is a cellular structure primarily involved in movement and sensory functions, such as moving fluid or sensing the environment, rather than being directly involved in cell division like the other options.
