The things with winter and overnight freeze are that this change of the weather can seriously harm the crop and do irreversible damage.

To prevent this, farmers use some methods.

One is the usage of heaters, not allowing the freeze to set.

Another one is to spray the crop with water before the predicted overnight freeze. When water freezes and turns into ice, it releases latent heat. Then, the ice that builds upon the plant will insulate it from the colder surrounding air temperatures.

How can gel electrophoresis be used to help illegal poaching of great white sharks?
statuscvo [17]

Explanation:

Gel electrophoresis is one simple and cheap laboratory technique used in profiling. In this case, it can be used to identify Great White Sharks using their proteins or DNA. This way, even if the fish is completely mutilated into the meat, the species can still be identified helping policies to be enforced.

DNA or proteins of a sample of suspected meat is processed and passed through gel electrophoresis. The bands that form are then compared with a standard to check if the bands match. A match indicates that the meat is from a Great White Shark.

Answer:

mRNA:   A-U-G-C-A-U-U-A

Explanation:

Given DNA template: T-A-C-G-C-T-A-A-T

Newly transcribed  mRNA:  A-U-G-C-A-U-U-A

Transcription is a process that uses DNA template strand to make RNA strands. The process occurs in nucleus. The nucleotide sequence of DNA template is always complimentary to its respective RNA sequence.

Here, thymine of DNA template strand pairs with adenine of newly formed RNA. Adenine of DNA template would pair with uracil of RNA. Guanine of DNA template pairs with cytosine.

What is photosynyhesis and cellular respiration?
Alex787 [66]

Photosynthesis is the process through which plants use sunlight and carbon dioxide to make food to sustain themselves. Cellular Respiration is when cells use oxygen and water to create a food source for the cell. The formula for photosynthesis is the same for cellular respiration except it's backwards. Hope this helps.

How is a society likely to address the problem of overuse of wildlife
Marianna [84]

Answer:

C. By creating laws or traditions that regulate hunting and fishing

Explanation:

Wildlife resources refer to wild animals (terrestrial, aquatic etc) in their natural habitat. Wildlife is an integral part of our society, however, they are being overexploited by human activities.

According to the options in the question, one way to address the problem of over use of wildlife resources is by creating laws or traditions that regulate hunting and fishing. Laws that compel hunting and fishing, which are the means humans over use wildlife, will help bring the rate at which these resources are used.

For example, creating a law that prohibits hunting in certain areas will help preserve wildlife in that area because it is a punishable offence by the law to hunt. Hence, wildlife resources will be preserved.
