Frogs have their way of avoiding the predators like camouflage, squirting the poisonous liquid out of their system and through their vestigial thumbs. This organ helps them by avoiding predation by stealth which makes them quiet and silent in moving so that predators won't notice them readily.

Why do you think it is Important to communicate your results even if your experiment did not go as planned?
Anna71 [15]
It is important because others do not make the same mistakes. Also, you can compare results. For example, if you do an experiment on high high bouncy balls bounce and you get 16 inches from 5 feet up, others need to know so they can experiment and maybe try things differently, and then compare results. So then you can see if you got roughly the same answer. Please give brainliest answer if this helped.

Tube A contains 1ml of phage stock that has been added to 9ml sterile media. Tube B contains 1ml from Tube A that has been mixed
natulia [17]

Answer:

1/1000 or 0.001

Explanation:

Serial dilution refers to the systematic dilution of the known concentration through successive suspension of initial volume to a fixed value of diluent.

In the given question, the serial dilution is performed in which the dilution factor will be

DF= volume of added solution / total volume of solution

For tube A

= 1/ 1+9

=1/10 or 10 folds.

For tube B

= 1/10 x 1/10

= 1/100 or 0.01

For Tube C

= 1/10 x 1/10 x 1/10

= 1/1000 or 0.001

Therefore, total dilution of tube C will be 0.001 or 1/1000.

In peas, green pods (g) are dominant over yellow pods. if a homozygous dominant plant is crossed with a homozygous recessive pla
slavikrds [6]
Based on the assumptions above, the Parental generation will have a genotype of GG and gg. This means the f1 generation will have a heterozygous genotype. In a Punnet square it will look like this:
     G     G
g  Gg    Gg
g  Gg    Gg

The phenotype of the F1 generation then will be Green. This is because the dominant trait or G will be expressed in a Gg combination. In other words, as long as there is a capital letter in the Genotype combination, the trait represented by the capital letter will be expressed.  

Now if you have two plants from the F1 generation crossed, some variety will appear. Taking the genotype of the two plants in that generation, Gg, we can construct another Punnet square to see the result:

      G     g
G  GG  Gg
g   Gg   gg

The phenotype will then be the following:
3 out of 4 off springs will be phenotype green.
1 out of 4 off springs will be phenotype yellow

In other words, there is a 75% chance of having a green off spring and a 25% chance of having a yellow off spring.
