The role of oxygen in cellular respiration is to make water molecules. hence, option (D) is correct.

<h3>What is Cellular respiration ?</h3>

Cellular respiration is the process in which cells break down molecules for energy.

The cells use oxygen to break down food in the form of glucose to produce water and release carbon dioxide.

During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.

In this reaction, energy is produced in the form of ATP that is used by the cell for its various activities.

Thus the correct answer is option D.

The following Lewis diagram represents the valence electron configuration of a main-group element. This element is in group 2A A

Paraphin [41]

<u>Answer:</u> The symbol of the ion formed is $Ca^{2+}$

<u>Explanation:</u>

An ion is formed when a neutral atom looses or gains electrons.

When an atom looses electrons, it results in the formation of positive ion known as cation.
When an atom gains electrons, it results in the formation of negative ion known as anion.

Electronic configuration is defined as the representation of electrons around the nucleus of an atom.

Number of electrons in an atom is determined by the atomic number of that atom.

The element present in Group 2-A and in period 4 is Calcium (Ca)

Electronic configuration of Ca atom: $1s^22s^22p^63s^23p^64s^2$

This atom will loose 2 electrons to attain stable electronic configuration similar to Argon element (noble gas)

The electronic configration of $Ca^{2+}\text{ ion}=1s^22s^22p^63s^23p^6$

Hence, the symbol of the ion formed is $Ca^{2+}$

Referring to the article, which of the following is associated with the use of genetic engineering to clone farm

malfutka [58]

D. All of the given statements are true in context of animal cloning.

Explanation:

Cloning is the method in which a similar genetic copy is produced.

Animal cloning is a complex process in which an organism of similar type is produced with same DNA to each other.

Mostly successfully cloned animals in live are cattle,sheep,goats...

Scientists have also cloned rats,mice,rabbits,horses...

This animal cloning is used for farming by the farmers which gives acceleration in their crop production.

Animal cloning have showed some adverse affects in sheep, and other mammal animals regarding issues in their organs like liver,heart,brain etc.

The success rate is very low like 10% in animal cloning due to many reasons such as surviving from birth to the cloned animals.

The ΔHvap of a certain compound is 49.09 kJ·mol–1 and its ΔSvap is 53.69 J·mol–1·K–1. What is the boiling point of this compound

rusak2 [61]

Hey there !

<span>Convert Joule to KJ :
</span>
1 j ---------------- 0.001 kj
53.69 j ----------- Kj

Kj = 53.69 * 0.001

=> 0.05369 Kj

T = ΔH / <span>ΔS

T = 49.09 / 0.05369

T = 914.32ºC</span>

Be sure to answer all parts. What is the effect of each of the following on the volume of 1 mol of an ideal gas? (a) The pressur

aksik [14]

Answer

A)The volume decreases by a factor of 4

B), the volume has increased by factor of 2

Explanation:

A)Given:

P1= 760Kpa

P2 =202Kpa

The temperature changes from37C to155C

There is increase In pressure from P1 to P2

P1= 760torr.

We need to convert to Kpa

But, 1atm= 760torr

Then 760torr 101000pa

Then 101000pa = 101Kpa

We need to convert the temperature from Celsius to Kelvin

T1= 37+273= 310K

But from ideal gas, we know that PV = nRT where nR is constant

Where P= pressure

V= volume

T= temperature

n = number of moles

(P1V1/T1)=(P2V2/T2)

V1/V2 = P2/P1 * T1/T2

V1/V2 = (202/101)*(310/155)

V1/V2=4

$V2= V1/4$

Therefore, the volume has decreased by factor of 4

Given:

P1= 2atm

P2 =101Kpa

The temperature changes from 305K to 32C

There is increase In pressure from P1 to P2

P1= 2atm

We need to convert to Kpa

But, 1atm= 760torr

Then 760torr 101000pa

Then 101000pa = 101Kpa

P1= 202.65kpa

We need to convert the temperature from Celsius to Kelvin

T2= 32+273= 305K

But from ideal gas, we know that PV = nRT

Where P= pressure

V= volume

T= temperature

n = number of moles

(P1V1/T1)=(P2V2/T2)

V1/V2 = P2/P1 * T1/T2

V1/V2 = (202/101)

V1/V2 = (101/202.65)*(305/305)

V1/V2 = 1/2

$V2=2V1$

Therefore, the volume has increased by factor of 2
