<u>Answer:</u> When oppositely charged species interact.

<u>Explanation:</u>

Ionic compound is defined as the compound which is formed by the complete transfer of electrons from one element to another element.

In these compounds, oppositely charged ions are attracted towards each other to form a compound.

<u>For Example:</u> NaCl is formed by the attraction of $Na^+\text{ and }Cl^-$ ions. So, same number of oppositely charges maintain electrical neutrality.

Electrical neutrality in a compound is achieved when atoms forming a compound have same number of opposite charges. Basically the charges on cation is balanced by the charges on anion.

Select the true statements about eicosanoids. a. Eicosanoids are broken down within seconds to inactive residues. b. Arachidonic

Evgen [1.6K]

Answer: the true statements about eicosanoids includes options A,B,D,E

Explanation:

EICOSANOIDS are mostly produced from the precursor arachidonic acid, a C20 polyunsaturated fatty acid. They are broken down within seconds to inactive residues after synthesis.High concentrations of eicosanoids are necessary for effective action.The three major types of eicosanoids includes:

-prostaglandins,

- thromboxanes, and

- leukotrienes.

Depending on the above types mentioned, they play a role in inflammation, pain, fever promotion, blood pressure regulation, and blood clotting. They also influence the immune response and certain respiratory and reproductive processes.

However, eicosanoids are NOT transported in the blood stream to their site of action RATHER they exert their effects on the tissue where they are synthesized.

A 3.50 g sample of an unknown compound containing only C , H , and O combusts in an oxygen‑rich environment. When the products h

statuscvo [17]

Explanation:

First, calculate the moles of $CO_{2}$ using ideal gas equation as follows.

PV = nRT

or, n = $\frac{PV}{RT}$

= $\frac{1 atm \times 4.41 ml}{0.0821 Latm/mol K \times 293 K}$ (as 1 bar = 1 atm (approx))

= 0.183 mol

As, Density = $\frac{mass}{volume}$

Hence, mass of water will be as follows.

Density = $\frac{mass}{volume}$

0.998 g/ml = $\frac{mass}{3.26 ml}$

mass = 3.25 g

Similarly, calculate the moles of water as follows.

No. of moles = $\frac{mass}{\text{molar mass}}$

= $\frac{3.25 g}{18.02 g/mol}$

= 0.180 mol

Moles of hydrogen = $0.180 \times 2$ = 0.36 mol

Now, mass of carbon will be as follows.

No. of moles = $\frac{mass}{\text{molar mass}}$

0.183 mol = $\frac{mass}{12 g/mol}$

= 2.19 g

Therefore, mass of oxygen will be as follows.

Mass of O = mass of sample - (mass of C + mass of H)

= 3.50 g - (2.19 g + 0.36 g)

= 0.95 g

Therefore, moles of oxygen will be as follows.

No. of moles = $\frac{mass}{\text{molar mass}}$

= $\frac{0.95 g}{16 g/mol}$

= 0.059 mol

Now, diving number of moles of each element of the compound by smallest no. of moles as follows.

C H O

No. of moles: 0.183 0.36 0.059

On dividing: 3.1 6.1 1

Therefore, empirical formula of the given compound is $C_{3}H_{6}O$ .

Thus, we can conclude that empirical formula of the given compound is $C_{3}H_{6}O$ .

Two proteins interact to form a multimeric complex. When one of the proteins is mutated, there is a substantial loss of function

ololo11 [35]

Answer:

<h2>4. dominant negative</h2>

Explanation:

Mutation is the process in which sudden changes take place within the sequence of amino acids that causes different type of problems. On the basis of nature and conditions mutation can be classified as dominant negative, neomorphic and some others types. Dominant mutation is also called as antimorphic mutation and changes the functions of the molecules that are proteins.
