1. Not the first option because there are too many Oxygen molcecules on the right. ( 2O:  3O)

2. Not the second option because, again the oxygen's are not balanced. (6O:8O)

3.Correct! this is a balanced equation as there are equal amounts of all the molecules on each side of the reaction.

4. Not the fourth one because the Magnesium(Mg) are not balanced. (2Mg:1Mg)

Explanation:

Foods produced from or using GM organisms are often referred to as GM foods.

GM foods are developed and marketed because there is some advantage either to the producer or consumer of these GM foods. GM seed developers wanted their products to be accepted by producers and have concentrated on innovations that bring direct benefit to farmers and generally the food industry.

One objective for developing plants based on GM organisms is to improve crop protection. The GM crops currently on the market are mainly aimed at an increased level of crop protection through the introduction of resistance against plant diseases caused by insects or viruses or through increased tolerance towards herbicides.

Resistance against insects is achieved by incorporating into the food plant the gene for toxin production from the bacterium Bacillus thuringiensis. GM crops that inherently produce this toxin have been shown to require lower quantities of insecticides in specific situations, where pest pressure is high.

Which of the following is false? a. an apoenzyme can catalyze its reaction without its cofactor b an organic cofactor can be cal
ozzi

Answer: Option (a) is the correct answer.

Explanation:

A protein part of an enzyme is known as an apoenzyme. An apoenzyme combines with a cofactor, it is known as holoenzyme.

Without a cofactor an apoenzyme cannot function as cofactor helps in the formation of an active enzyme system and provides a specific site on enzyme for the substrate.

Whereas a non-protein chemical compound or metal ion that helps in the activity of enzyme as a catalyst is known as a cofactor. A metal ion cofactor can be bound directly to the enzyme or to a coenzyme.

The organic non-protein molecules which bind to the protein molecule to form an active enzyme is known as a coenzyme. Coenzymes are small size molecules which help the enzymes to act as a catalyst.

Therefore, we can conclude that the statement an apoenzyme can catalyze its reaction without its cofactor, is false.

A typical person has an average heart rate of 75.0 beats/min. Pay close attention to significant figures in this question.
frozen [14]

The number of beats  the person have in 1.7 years is  6.7 x 10⁷ beats.

<h3>Number of beats of the person</h3>

The number of beats of the person is calculated as follows;

n = bt

where;

  • b is the beat rate
  • n is number of beats
  • t is time or duration

b = 75 beats/min

t = 1.7 years = 893520 mins

n = 75 beats/min x 893520 mins

n = 67,014,000

n = 6.7 x 10⁷ beats

Thus, the number of beats  the person have in 1.7 years is  6.7 x 10⁷ beats.
