Explain how the discoveries by Rosalind Franklin helped Watson and Crick build an accurate model of DNA.How can DNA be used to help solve a crime?

Answers

Answer:

Rosalind Franklin had taken the first picture showing the structure of DNA, called the double helix. This helped confirm what Watson and Crick had thought, thus leading them to make the first accurate model. DNA can be used to solve a crime because it can prove a certain person did something. EX: finding hair and who it belongs to/ finding finger prints and who they belong to.

THIS IS CROSSING OVER- DNDNNFNCBXJXBDJBXJX WHY DO YOU HAVE SUCH HARD QUESTIONS-

The Offspring produced by a cross between two given types of plants can be any of the three genotypes denoted by A, B, and C. A theoretical model of any of the three genotypes denoted by A, B, and C should be in the ratio 1:2:1. For experimental verification, 100 plants are bred by crossing the two given types. Their genetic classifications are recorded. Do these data contradict the genetic model

Answers

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:

Crossed genotypes: twoGenotypes among the offspring; Three → A, B, and CExpected phenotypic ratio → 1:2:1Total number of individuals, N = 100A = 18 individualsB = 55 individualsC = 27 individuals

So, let us first state the hypothesis:

H₀= the population is equilibrium for this locus → F(A) = 25%,  F(B) = 50%, F(C) = 25%  H₁ = the population is not in equilibrium

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

Observed                         18                            55                         27 Expected                         25                           50                         25 (Obs-Exp)²/Exp                1.96                        0.5                        0.16

(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  

∑ is the sum of the terms O are the Observed individuals: 2 in chamber B, and 18 in chamber A.  E are the Expected individuals: 10 in each chamber  

= ∑ ((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:

A majority of tornadoes that occur in the United States, occur in the  Midwest and Southeast region of the United States.

Explanation:

Tornadoes can impact just about every U.S. state, but the majority of these storms are concentrated in states throughout the Midwest and Southeast. In fact, of the average 1,137 tornadoes that occur in the United States each year, 64% of them form in states located in “Tornado Alley” and “Dixie Alley”, two regions with a disproportionately high frequency of tornadoes due to atmospheric conditions that persist for long stretches of the year.

With an average of 140 tornadoes annually, Texas is the most tornado-prone state in the U.S., followed by Kansas with 80 and Florida with 59, according to National Oceanic and Atmospheric Administration data.

Top five states with the most tornadoes

Texas - 140

Kansas - 80

Florida - 59

Oklahoma - 56

Nebraska - 54

Bottom five states with the least tornadoes

Alaska - 0

Hawaii - 0

Answers

Answer:

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.

i am sorry if this is wrong

The following pieces of evidence does not mid-ocean ridges are formed Mid-ocean ridges are found on the bottom of most oceans.

What is mid-ocean ridges?

The central parts of the oceans have mid-ocean ridges. The mid-ocean ridges are volcanic underwater mountain ranges.

There is constant propelling of magma, and as the magma cools off quickly it creates new crust.

This results in the mid-ocean ridges gaining heights of up to 1.5 km above the surrounding area.

So, option B is correct.

What are evolutionary relationships?

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.
