Answer:

Heat is taken in from the surrounding environment.

Explanation:

There are two groups of reactions endothermic and exothermic.

Endothermic reactions have a positive ΔH. This means that in order for the reaction to take place, a certain amount of energy is needed to break and form the bonds between the newly formed compound/s.

Exothermic reactions have a negative ΔH. This means that when the reaction takes place, there is still energy "left over" after all the bonds have been formed, this leads to the expulsion of that energy into the environment.

Which of the following best explains why the latitude of a region influences its climate?
Rudik [331]

Answer:

"The latitude of a region determines how much sunlight the area receives" this statement says about why the latitude of a region influences its climate.

Explanation:

The latitude determines the sunlight of the area receives because, the more the latitude the sharper will be angle of the sun's rays which will reach the surface. Means that the rays of the sun are being spread over the broader area. Hence, More the latitude receive will be the less than the lower latitude areas located nearer to the equator. As, we know the sun's ray first strikes over the Earth's surface which is near the equator as these places receive direct solar radiation. At greater latitude the solar radiations gets spread in more area and hence the temperature also reduces.

Define mutagen and describe how mutagens are used in genetic research.
Salsk061 [2.6K]

A mutagenic agent is any chemical, physical or biological compost that can induce a mutation in the cell's DNA, making this mutation pass to the next generation.

Mutagenic agents are widely used in the fields of biotechnology, genetic engineering, medicine and agroindustry. This is because these agents have helped in the advancement and development of new technological tools.  

In genetic research some bacteria and viruses are used by agribusiness companies to obtain transgenic beings. These mutagenic (biological) agents act as vectors of laboratory-created genes that will insert these genes into an organism to be modified. It could be, for example, a gene that will improve maize resistance against a pest. Thanks to mutagenic agents, this genetic information can be passed on to the organism, in this case, the plant.
