How does a frog get rid of urea/urine? Question 4 options: gills lungs heart kidneys
Mrrafil [7]
A frog gets rid of it's urine through the kidneys because the heart pumps blood throughout the body, the lungs are used to take in O2 molecules and gills are use to filter out the hydrogen in HO2 so they can breathe under water. However the kidneys are part of the waste disposal system (what makes us need trip to the bathroom ever now and then) therefore that is the answer.<span />

There is a population where the frequencies of allele 1 and allele 2 are 0.7 and 0.3, respectively. Allele 1 has a selection coe
Lorico [155]

Answer:

0.8

Explanation:

There is a population where the frequencies of allele 1 and allele 2 are 0.7 and 0.3, respectively

Let's use GG to represent allele 1

Let's use gg to represent allele 2

So we can equally say that;

GG = p = 0.7

gg = q  = 0.3   ( from Hardy-Weinberg Equilibrium)

So, given that the selection coefficient = 0.2

We known that the cross between GG and gg will definitely results to (GG,Gg and gg)

Then the fitness of these genes can be represented as:

1 - s, 1 and 1 - t respectively.

Thus. the allele 1's genotype fitness can be determined as

= 1 - s    ( where s is the selection coefficient)

= 1 - 0.2

= 0.8

Punnet squares are a useful tool for predicting what the offspring will look like when mating plants or animals. Reginald Crundall Punnett, a mathematician, came up with these in 1905, long after Mendel's experiments. Let's take a look at how Punnet squares work using the yellow and green peas example from im not sure about the tree by three thing but maybe this will help :)

Most of the oxygen transported by the blood is___________.
Pie

Answer:

c. Bound to hemoglobin.

Explanation:

The oxygen is relatively insoluble in plasma. At normal atmospheric pressure, only 0,3% of oxygen dissolves. That why there are respiratory pigments that <u>elevate almost 70 times</u><u> the capacity to transport O₂ of blood</u>. The most common respiratory pigments are hemoglobin (in all vertebrates and some invertebrates) and hemocyanin (in mollusks and arthropods).
