Answer:

7.5mL

Explanation:

Comsidering the definition of dilution, 7.5 mL of the stock solution  of 2 M are required to prepare 100 mL of 0.150 M solution.

Dilution is a procedure by which the concentration of a solution is lowered. It is achieved by adding more solvent to the same amount of solute.

Then the amount of solute does not vary, but the volume of the solvent does: when more solvent is added, the concentration of the solute decreases, as the volume of the solution increases.

A dilution is mathematically expressed as:

Ci×Vi = Cf×Vf

where

In this case, you know:

Replacing in the definition of dilution:  

2 M×Vi= 0.150 M×100 mL

Solving:

[tex]Vi=\frac{0.150 M x 100 mL}{2 M}[/tex]

Vi= 7.5 mL

In summary, 7.5 mL of the stock solution  of 2 M are required to prepare 100 mL of 0.150 M solution.

Complete question:

The offspring produced between two given types of plants can be any of the three genotypes, denoted by A, B and C. A theoretical model of gene inheritance suggests that the offspring of types A, B and C should be in a 1:2:1 ratio (meaning 25% A, 50% B, and 25% C). For experimental verification, 100 plants are bred by crossing the two given types. Their genetic classifications are recorded in the table below.

Genotype       Observed frequency

    A             →        18 individuals

    B             →        55 individuals

    C             →        27 individuals

Do these contradict the genetic model?  

Use a 0.05 level of significance.

Determine the chi-square test statistic.

Answer:

Do these contradict the genetic model? No, according to the chi-square test, there is not enough evidence to reject the null hypothesis of the population being in equilibrium.  

Explanation:

Available data:

So, let us first state the hypothesis:

Now, let us calculate the number of expected individuals, according to their expected ratio.

4 -------------- 100% -------------100 individuals

1 ---------------  25% -------------X = 25 individuals A

2 --------------  50% -------------X = 50 individuals B

1----------------- 25%--------------X = 25 individuals C

                                                  A                             B                           C

(Obs-Exp)²/Exp

A)  (18 - 25)²/25 = 49/25 = 1.96

B)  (55 - 50)² / 50 = 25/50 = 0.5

C)  (27 - 25)²/25 = 4/25 = 0.16

Chi square = X² = Σ(Obs-Exp)²/Exp  

X² = ∑ ((O-E)²/E) = 1.96 + 0.5 + 0.16 = 2.62

Freedom degrees = 2

Significance level, 5% = 0.05  

Table value/Critical value = 5.99

X² < Critical value

2.62 < 5.99    

These results suggest that there is not enough evidence to reject the null hypothesis. We can assume that the locus under study in this population is in equilibrium H-W.  

Answer:

By decoding information with the help of transfer RNA (tRNA).

Explanation:

The cell uses the information in DNA with the help of transfer RNA (tRNA) to synthesize a protein because transfer RNA (tRNA) decode a messenger RNA (mRNA) in order to produce proteins according to the information present in messenger RNA (mRNA). The information about protein is stored in a gene's DNA which is passed to a RNA in the cell nucleus which is responsible for formation of copies of DNA in the process of translation. So the cell uses the information of gene's DNA with the help of RNA molecules.

Answer:

B sounds like a sensible choice

Explanation:

The extinct dinosaur and modern bird share a common ancestor. So the correct option is B.

Systematics, taxonomy, phylogenetics, and evolution are the four approaches used to investigate evolutionary connections. The branch of science known as systematics is concerned with classifying species and figuring out their relationships. It has two primary branches that may be separated:

Organisms are classified, given names, and grouped in taxonomy. A population, species, genus, or higher-level grouping like a family, order, class, phylum, kingdom, or domain can all be considered as a group or taxon. The word taxon is pluralized as taxa. The determination of evolutionary links or patterns of descent of species is via the study of phylogenetics.

The species of living things that exist now are all descendants of earlier ones. This is the result of evolution or merely time-related change. Branching evolutionary trees can be used to illustrate the evolutionary links between ancestors and their offspring. An evolutionary tree shows which ancestors gave rise to which descendants, much like your family tree does.

Therefore the correct option is B.

Certain plants contain compounds similar to ecdysone which serve as a defense against insects. False

Juvenile hormone levels are high in insect larvae, but must decrease in order for metamorphosis to occur. True.

Chemicals similar to ecdysone and juvenile hormone are widely used commercially to control insect pests. True

Explanation:

The plants produce toxic chemicals such as terpenoids, alkaloids, anthocyanins, phenols, and quinones as a defense against insects. Juvenile hormone levels are high in insect larvae but its concentration decrease when the insect transform into adult stage and in order to  occur metamorphosis. Ecdysone and juvenile hormone are widely used as insecticide because it prevents the insects to transform from larva to adult so if they can't mature they can't harm the plants or other things of our environment.

Complete question:

A scientist used the amino acid sequence of cytochrome c in different species to consider evolutionary relationships.

The data below summarizes the numbers of differences in the amino acid sequences of cytochrome C found in the selected species

Species compared              Number of differences

Human-chimpanzees                              0

Human-Rhesus monkeys                        1

Human-Horses or Donkeys                    7

Human-Cow, Pigs or sheeps                  7

Human-Rabbits                                        7

Mammals-Birds and reptiles                  10-15

Mammals-Fishes                                    18-20

Mammals-Plants                                     45-48

Interpretation of the data supports which of the following statements?

(A) Rhesus monkeys are more closely related to rabbits than they are to horses.

(B) Horses and cows have identical amino acid sequences in their cytochrome c.

(C) Humans are more closely related to rabbits than they are to rhesus monkeys.

(D) Plants and animals have no similarities at all.

(E) Mammals are more closely related to reptiles than they are to fish.

Answer:

(E) Mammals are more closely related to reptiles than they are to fish.

Explanation:

So, what you need to do here is to compare the number of differences found in each comparison. Remember that this information is only regarding cytochrome C. For instance, we can see that between humans and chimpanzees, the number of differences is 0. Their amino acid sequences do not differ at all. On the contrary, the comparison of mammals and plants threw a value of 45-48 differences, meaning that they are very different from each other, almost 50%.

So, this is how you need to interpret the values of the differences in this table. Now, let us go to the options,

(A) Rhesus monkeys are more closely related to rabbits than they are to horses. Rhesus monkey was not compared to any group other than humans, so we could not say that they are more related to one animal or the other.

(B) Horses and cows have identical amino acid sequences in their cytochrome. When comparing humans with horses and then humans with cows, the number of differences was the same -7-. But these results do not indicate which are the differences. Remember that we are comparing amino acid sequences, so probably the number of differences of each group with humans is the same, but the amino acid sequences between horses and cows are not.

(C) Humans are more closely related to rabbits than they are to rhesus monkeys. Humans and rhesus monkeys express only one difference in the amino acid sequence, while humans and rabbits exhibit seven differences. This result means that humans are more closely to rhesus monkeys related than they are to rabbits.

(D) Plants and animals have no similarities at all.

As we mentioned before, plants and mammals have a difference of almost 50% in their amino-acidic sequences. It does not mean that the other 50% is also different.

(E) Mammals are more closely related to reptiles than they are to fish.

The amino acid sequence of mammals and reptiles show 10-15 differences

The amino acid sequence of mammals and fish show 18-20 differences

So yes, mammals seem to be more related to reptiles than to fishes because the number of differences with reptiles is fewer.
