Question

How do scientists create GMOs in the lab?

- both gene deletion and gene insertion

- gene insertion

- gene deletion

Spontaneous chemical reactions are:

- endergonic and release energy

- exergonic and their products contain more energy

- exergonic and release energy

Humans metabolize by:

- ACR and sometimes anaerobic cellular respiration

- ACR and photosynthesis

- fermentation only

In a balanced chemical reaction,

- the subscripts balance the number of molecules and the arrow points to the reactants

- the coefficients balance the number of molecules and the arrow points to the products

- the subscripts balance the number of molecules and the arrow points to the products

- the coefficients balance the number of molecules and the arrow points to the reactants

Following is the - complete Answer -&- Explanation: for the given: Question Set...in...typed format...

--------------------------------------------------------------------------------------

$\Rightarrow$Question - 1:

$\Rightarrow$Answer:

Option - ( 1 ): both by gene deletion and gene insertion.

$\Rightarrow$Explanation:

Genetically Modified Organism ( i.e. GMOs ) can be created in the lab, by isolation of a gene ( i.e. isolation of a strain of gene) from an existing strain of gene: and then : insertion of the strain of isolated gene: into the genetic elements of the host organism.

$\Rightarrow$Question - 2:

$\Rightarrow$Answer:

Option - ( 3 ): exergonic and release energy

$\Rightarrow$Explanation:

We know, Exergonic reactions: are those reactions, in which: the change of the free energy: is negative, and therefore, it consequently causes, a release of energy. Since, as we know, in case of spontaneous reactions: the free energy of the products: will be lower than, the free energy of the reactants. Thus the net change of the free energy of reaction: will  be negative, i.e. there will be a release of energy.

Since, as we can see,both Exergonic reactions, and Spontaneouis reactions: release energy: we can surely say that: our Answer: will be: Spontaneous reactions are Exergonic and they release energy .

$\Rightarrow$Question - 3:

$\Rightarrow$Answer:

Option - ( 3 ): Fermentation only

$\Rightarrow$Explanation:

Since we know, humans don't  metabolize by anaerobic cellular respiration, whereas, respiration happens most often, by : fermentation: in some cells of the human body, we can surely say that our answer: will be the following: i.e. by Fermentation Only...

$\Rightarrow$Question - 4:

$\Rightarrow$Answer:

Option - ( 2 ): the coefficients balance the number of molecules, and the arrow points to the products.

$\Rightarrow$Explanation:

Actually, in balanced reactions: the both subscripts and stoichiometric coefficients: determine , whether the number of atoms , of the same element, is balanced, and are equal on both sides: of the balanced chemical equation: And as we know, the LHS: of a balanced reaction: indicate the reactants: and the RHS: indicate the products.

Thus, the given: Option - ( 2 ) : will be our answer.
