Biology
1 answer:
masya89 [10]3 years ago
7 0

Answer:

An enzyme is a molecule that speeds up a reaction. In the case of DNA reproduction, enzymes not only speed up the reaction, they are necessary for DNA reproduction.

Explanation:

An enzyme is a molecule that speeds up a reaction. In the case of DNA reproduction, enzymes not only speed up the reaction, they are necessary for DNA reproduction.

Recall that DNA is a long strand with a many repeating base pairs. In order for DNA to reproduce, the base pairs must be split apart. One half of the strand is then used as a template to build a new strand of DNA.

The enzyme helicase is responsible for splitting DNA along the base pairs. Helicase moves along the DNA strand unzipping the strand just as a zipper.

How will hurricane risks and impacts change over the next 100 years?
Papessa [141]

Answer:

Hurricanes will become more frequent and expand to new areas.

Explanation:

Global warming will rise sea temperatures worldwide. This means conditions for hurricanes will be met more often (they only form in higher than average sea temperatures). That means more hurricanes will form in the future. Also because of rising sea temperatures new areas will be effected by hurricanes as they will meet the threshold required for hurricanes to form.

How can one determine the median of a data set?
Tema [17]
To determine the median of a data set, you need to put all of the values you have in their numerical order. Count how many figures there are overall, if there is an even number, then the median will be the middle number. if there is an even number, then to find the median number you need to determine the mean of the two numbers in the middle. To determine the mean of a data set, you first need to add together all the values within the set. Next, count up how many overall values there are, and then divide the previous total by the number of values that there are.
