Answer:

The two genes are come from one chromosome.

Explanation:

a. One haploid can synthesize uracil, another one can synthesized leucine. Assume that there is not any mutation, two different amino acids should be encoded by different genes.

b. The genotypes of two haploid strains are different. Each has contained single chromosomes, as same as gametes in any Eukaryotic organism.

c. Firstly, yeast is an Eukaryotic organism, diploid. It means they have chromosomes in pair. Secondly, haploid cell contains half of the chromosomes from parent cell. Due to the theory of meiosis, the half chromosome encoding leucine go to one haploid cell, the other encoding uracil go to another haploid cell. If they are from different chromosomes, there is a chance to have a haploid which can produce both uracil and leucine. Thus, the only possible answer is that they are from a chromosome in opposite long-arm or short-arm of the chromosome, which is later divided into two haploid.

d. There is not any haploid strain which is able to produce both uracil and leucine.

A fish is swimming around the 720-meter perimeter of her pond. If she swims 10 laps in 120 minutes, what is her average speed in
statuscvo [17]

Answer:

The average speed of the fish is:

  • <u>60 m/min</u>

Explanation:

You must take into account that the fish swims 10 laps, so you must multiply the perimeter by 10 to obtain the total meters swam:

  • 720 m * 10 = 7200 meters.

Now, you just must divide the total meters swam by the number of minutes that the fish took to do this, so:

  • 7200 m / 120 min = <u>60 m/min </u>

Remember, ever you do an exercise like this, you must check the units, I mean, the units that the exercise wants to be the same you use, in this case, the average speed of the fish is 60 m/min.

Which cues might cause a plant to respond?
IgorLugansk [536]
A tropism is a turning toward or away from a stimulus in the environment. Growing toward gravity is called geotropism. Plants also exhibit phototropism, or growing toward a light source. This response is controlled by a plant growth hormone called auxin.
