Answer:

Explanation:

y=-2/3x+7 you multiply everything by 3 to cancel the fraction

3y=-2x+21 add 2x to both sides cuz u want the x and y on the left side for standard form

2x+3y=21

Answer:

2x + 3y = 21

Explanation:

We have to work backwards here, in order to find out what the standard form of this equation would be.

So it's safe to say, since the slope has 3 as the denominator, we would've divided by 3 at some point when turning the standard form to slope-intercept form.

Dividing is usually the last step, and we do this to isolate the y. So this means that 3 was in front of y instead of x. This also means that the y-intercept was able to be divided by 3. (We can rule out the second and last options, for these reasons.)

Now the problem is looking like this:

3y = -2x + 21

Next we would've had to move the 2x in order for it to be on this side, so now we have to move it back. So we will add 2x on both sides to get 2x + 3y = 21.

Here's your answer. Sorry the explanation is a little lengthy btw.

Hope this helps you though :)

Why does sexual reproduction result in more genetic variation in a species than asexual reproduction?

goldenfox [79]

Answer:

Explanation:

During asexual reproduction, the parent essentially clones their DNA to make their child. This means that there is very little possible variation, except for some occasional mutations. However, during sexual reproduction, the child gets the copy of DNA from both of their parents, and their features a mixture of their parents. This makes them not identical to either parent, unlike asexual reproduction. Therefore, the correct answer is choice B. Hope this helps!

Since there are no genes coding for carbohydrates and lipids, how do cells produce them?

lina2011 [118]

<span>Cell code for enzymes that can convert other molecules into carbohydrates, nucleic acids and lipids. Humans can synthesize 11 out of the 20 amino acids and bacteria can synthesize all 20. Plus bacteria can synthesize many of the vitamins that humans cannot, including vitamin C. As far as humans are concerned, we can make carbohydrates and glycogen from glucose. We use some amino acids to make nucleic acids and we can synthesize lipids and cholesterol from acetyl coA. There are certain types of fatty acids we can't synthesize and we must get them from our diet.</span>

Explain how the structure (order) of DNA can determine the structure of a protein. Use as many of the following terms as you can

jek_recluse [69]

The stages of DNA bases in a molecule can determine the order of amino acids in protein molecules. Groups of three bases called triplets represent different amino acids. This is the basis of the genetic code . A sequence of bases (genetic information) on DNA that codes for a protein is called a gene

You have a population of dogs with three alleles for teeth size: L (large), M (medium), and S (small). Individuals with SS, SM,

Dahasolnce [82]

Answer:

<em>Small teeth will be missing. </em>

Explanation:

As seen from the information of the question, that dogs having medium and long teeth will not carry any alleles for small teeth. So, if a certain viral disease eradicates all the dogs with small teeth, there will be no organisms left to carry genes for this trait. Over time, the medium teeth dogs and long teeth dogs will be more adapted to the environment. Hence, after 10 generations no small teeth dogs will be seen.
