Energy from an earthquake travels: C. as seismic waves that cause matter to vibrate.

Explanation:

The energy of an earthquake travels in the form of waves. These waves are referred to as seismic or earthquake waves. Earthquake waves are classified into two types: body waves and surface waves. Body waves move through the Earth's interior, whereas surface waves travel along the Earth's surface.

1) You have an electropherogram with a clean, three-locus profile:
STR locus #1 is 10, 14
STR locus #2 is 30 (only)
STR locus #3 is 3, 6
What is the random match probability of this profile? Fill in the blank:
"Approximately one in every
people, drawn randomly from the human
population, would be expected to have this three-locus profile.

Answers

Following the product probability rule and assuming independence among loci, the random match probability of this three-locus profile is 0.000853. See below the procedure for question number 2.

What does the product probability rule state?

The product probability rule allows us to calcuate the probability of occurrence of two or more events at the same time. It is about a joint probability of two or more events that might happen simultaneously, not excluding each other.

This rule is based on the dependence or independence of the events. Two events, A and B, are independent of each other if one of them does not affect the occurrence of the other one.

The rule establishes that the occurrence probability of two independent events -A and B- together is the multiplication product of the probability of occurring A by the probability of occurring B.

P(A∩B) = P(A) x P(B)

In the exposed example,

STR locus #1 has three alleles → 10, 11, 14STR locus #2 has four alleles → 27, 28, 28.2, 30STR locus #3 has three alleles → 3, 6, 7

The frequency of each allele is detailed in the table.

According to the electropherogram, the profiles are

STR locus #1 → 10, 14 → Heter0zyg0usSTR locus #2 → 30 → H0m0zyg0usSTR locus #3 → 3, 6 → Heter0zyg0us

Knowing the allele frequencies, we can get the genotypic frequencies,

   Locus               Allele frequency            Genotypic frequency

STR locus #1

10                                 0.22                    2xpxq = 2 x 0.22 x 0.18 = 0.079

14                                 0.18            

----------------------------------------------------------------------------------------------------  

STR locus #2

30                                 0.22                    p² = 0.22² = 0.048

----------------------------------------------------------------------------------------------------  

STR locus #3

3                                   0.45                    2xpxq = 2 x 0.45 x 0.25 = 0.225

3                                   0.25            

----------------------------------------------------------------------------------------------------

So, the probability, P, of getting these genotypes are,

P ₍₁₀₋₁₄₎ = 0.079P₍₃₀₋₃₀₎ = 0.048P₍₃₋₆₎ = 0.225

The random match probability of this profile is the probability of getting the three genotypes together.

Following the product probability rule and assuming that loci are independent from each other, the profile probability, PP, is

PP = P₍₁₎ x P₍₂₎ x P₍₃₎ x .... P₍ₙ₎

PP = (P₍₁₀₋₁₄₎ ) (P₍₃₀₋₃₀₎) (P₍₃₋₆₎)

PP = 0.079 x 0.048 x 0.225

PP = 0.000853

The random match probability of this three-locus profile is 0.000853.

To fill in the blank, you need to consider the population size -N- and the probability of getting this three-locus profile.  

Since I do not have the total number of individuals in the population, I will say that my population size, N = 500 individuals and I will make the calcs according to this number. You should follow the same procedure but use your N.

We know that the probability of getting this three-locus profile is 0.000853. This is the frequency of individuals carrying this genotype in the population.

To get the number of individuals with this genotype in the population, we need to multiply this frequency by the total number of individuals, N.

Nº of individuals with the three-locus profile = frequency x N

Nº of individuals with the three-locus profile = 0.000853 x 500

Nº of individuals with the three-locus profile = 0.4265 individuals.

Now we know that in a population of 500 individuals, there are 0.4265 individuals with the three-locus profile. Now we need to know the population size in which we can find 1 individual with this genotype.

0.4265 individuals with the three-locus profile-------- 500 individuals

1 individual -------------------------- X = (1 x 500) / 0.4265 = 1,172.33 individuals.

According to these calculations, approximately one in every 1,172.33 individuals, drawn randomly from the population, would be expected to have this three-locus profile.

Note: Remember to use the population size provided to you in this problem. The procedure is the same, but the population size -N- will be different.

Answer:

Dr. Temple Grandin changed the face of animal husbandry by creating a new, humane, and efficient way of processing meat. There are even vet clinics inspired by her to be 100% discomfort-free.

Explanation:

Hope this helps!

Dr. Temple Grandin, an American professor of animal science and a prominent advocate for animal welfare, has had a transformative impact on animal husbandry.

Despite facing challenges with autism, she leveraged her unique perspective and deep empathy for animals to revolutionize the way livestock is handled and treated in the agricultural industry.

Dr. Grandin is renowned for her innovative designs of livestock handling facilities that prioritize the welfare of animals. By understanding the sensory sensitivities of animals, she created more humane systems that reduce stress and fear during handling and transportation. Her designs include curved chutes and non-slip flooring, which encourage a calmer movement of animals, minimizing injuries and distress.

Dr. Temple Grandin's contributions to animal husbandry have been instrumental in promoting compassionate practices, reducing animal suffering, and fostering a greater understanding of the emotional needs of livestock. Her groundbreaking work continues to inspire positive change and serves as a testament to the potential for empathy and innovation to transform industries for the betterment of both animals and humans.

Answer:

C. A Scotland Yard investigator did this in the 1830s.

Reason:

In the 1830s, a Scotland Yard detective was among the first to utilize bullet comparisons to capture a culprit.

A Scotland Yard investigator did this in the 1830s. Therefore, option C is correct.

What are bullets?

A bullet is a kinetic projectile that is fired from a gun barrel as part of firearm ammunition. The majority of handgun bullets are formed of a lead-antimony alloy contained in a soft brass or copper-plated soft steel jacket, although they can also be made of copper, lead, steel, polymer, rubber, and even wax.

A softer lead core is enclosed in a tougher jacket made of steel or cupronickel in rifle and machine gun bullets. Bullets that penetrate armor have an inner core made of hardened steel.

Thus, a Scotland-yard investigator did this in the 1830s. This is true about using bullet comparison to solve crimes. Therefore, option C is correct.
