Red-eyed tree frogsa. are green and do photosynthesis, so they do not need to eat or drink.
b. are not frogs, because frogs never have red eyes.
c. live in banana trees.
d. none of the above

Answers

I believe ur answer is D.) None of the above, because frogs aren't producers, they hav red eyes becuz of adaptations, not that becuz frogs never do, and obviously, red eye tree frogs can live anywhere, it doesnt hav to be a banana tree, and banana trees aren't like contagious or anything...

Eight people who suffer from sinus infections volunteer to test a new medication that will relieve symptoms. The names of the volunteers are . . 1. Amanda . 2. Scott . 3. Tessa . 4. Jon . 5. Elizabeth . 6. Kevin . 7. Robin . 8. Mike . . Four of the volunteers will receive the new medication, while the other four will receive a placebo as part of a double blind experiment. Starting at the left of the list of random numbers below and reading from left to right, assign four people to be given the medication. . . 20742 05310 65921 01652 75532 95621 12097 . Who are the four people assigned ?

Answers

the easiest way to do this is by ignoring the 0, a nine, or those that has been used before and assign the four other numbers

So the answer would be :
- Scott
- Robin
- Jon
- Elizabeth

Hope this helps

Answer:

Use the first numbers to assign the treatment to the individuals.

Explanation:

The names of the individuals are:

1. Amanda: 20742

2. Scott: 05310

3. Tessa: 65921

4. Jon: 01652

5. Elizabeth: 75532

6. Kevin: 95621

7. Robin: 12097

8. Mike: (no number assigned)

I am assuming that the numbers that are random and are given to them in the order seen. First, remove all the persons that have a zero or 9 in front and no number assigned to their names . That leaves 20742 , 65921, 75532, 12097.

The four individuals would be Amanda, Tessa, Elizabeth and Kevin.

There are other ways to do this randomized selection, that also involves eliminating the numbers with zeros and those that have been used in the same numbers.

It can also be done by using the first two digits, also eliminating the zero and assigning the numbers from lowest to highest alphabetically in ascending or descending order.

Four volunteers will always be chosen based on any of these methods.

In one generation, the frequency of the A allele is 70 percent and the frequency of the a allele is 30 percent. What are the chances of an individual in the next generation having the genotype aa if the population is in genetic equilibrium? 49% 42% 30% 9%

Answers

Answer:

The correct answer would be 9%.

As the population is in genetic equilibrium, then the population must be following the Hardy-Weinberg equations:

p + q = 1 and

p² + q² + 2pq = 1

The frequency of A (dominant allele) in a population is 70 percent.

Thus, the value of p would be 70/100 which comes out be 0.7

Similarly, the value of q would be equal to 0.3

The frequency of individual with homozygous recessive genotype, that is, aa would be equal to q².

So, q² = $(0.3)^(2)$ ⇒ 0.09

Thus, the frequency of individual with genotype aa would be equal to 9 percent.

9%

Why?
The frequency for allele a is 30% or 0.3. Let's call this frequency p.
p^2 would then represent the frequency of genotype aa (this is is derived from the formula p^2+2pq+q^2=1 where p and q represent alleles a and A respectively. So p^2=aa, pq=Aa and q^2=AA)
0.3^2=0.09 or 9%

How are the benefits of wildfires in grasslands and northern forests similar?a. increased tree quantityb. increased food production for grazersc. increased amount of lichensd. all of the abovePlease select the best answer from the choices provided

Answers

The benefits of wildfires in grasslands and northern forests are similar - b. increased food production for grazers

Wildfires affect the ecosystem by

remove low-growing underbrush,
clean the forest floor of debris,
open it up to sunlight,
nourish the soil.

The grassland and northern forests ecosystem are maintained by wildfire.
It warms up the soil and reduces leaf litter.
It allows sunlight to penetrate and grow more food production for grazers

Are you referring to this question?
How are the benefits of wildfires in grasslands and northern forests similar?
a. increased tree quantity
b. increased food production for grazers
c.increased amount of lichensd. all of the above

If you are, the answer would be letter B.
Wildfires not only do they remove dead and decaying plants that act as fuel for future fires — ones that will be more intense and disastrous, wildfires work to eliminate dense foliage and thin out the forest allowing plants closer to the forest floor to come in more contact with sunlight and rain, “enabling a new generation of seedlings to grow”

>>>forest fires play a vital role in maintaining nature’s constant cycle.
