50 points and brainliest'!!!!!!!!!!!!!!!!!!!!!!!!Reliability and probability in forensic tests are important. When you look at matching a paint chip to a specific car, you are working to increase the probability that the right car matching your paint chip evidence will be found. Reliability means you have practiced and applied the correct procedures and processes for all your evidence testing, and you know you can trust the results. Some forensic tests are more reliable than others, and the best type of test or tests to use will usually depend on the kind of evidence that is present. If all types of evidence were present at a crime scene, which type of test would you choose based on its reliability and probability of accuracy? Identify which test you would choose and provide a detailed argument as to why you feel it has a high level of reliability in comparison to other types of evidence. Your answer should be at least two paragraphs in length and should include solid arguments for your choice. There is no wrong choice, just be sure to provide a convincing argument.

Final answer:

For forensic science, the Gas Chromatography-Mass Spectrometry (GC-MS) is highly reliable and accurate for identifying specific materials. In a case involving a paint chip, it accurately identifies the various elements and compounds in the paint and discriminates between different paint brands and types.

Explanation:

In the entire arsenal of forensic tests, one test stands out for its high reliability and accuracy in identifying specific materials: the Gas Chromatography-Mass Spectrometry (GC-MS). It has two main components: Gas Chromatograph, which separates the different components in a substance, and Mass Spectrometer, which identifies each of these components.

The GC-MS test is particularly effective when analyzing biological materials like blood, saliva, and even paint fragments. When dealing with a case involving a paint chip, for instance, GC-MS can not only identify the various elements and compounds in the paint but can discriminate between different paint brands and types, thereby increasing the probability of accurately matching the paint chip to a specific car.

A genetics researcher finds that a form of human albinism in a certain population is controlled by the recessive allele, a, for the absence of skin pigment and the completely dominant allele, A, for presence of skin pigment. If the recessive allele occurs in 30% of this population, what percent of the population has skin pigment but also carries the recessive allele?21 percent
42 percent
91 percent
51 percent

Answers

Answer:

Option A

Percent of the population that has skin pigment but also carries the recessive allele is $21\n$ percent

Explanation:

As per hardy-weinberg equation,

$p^2+q^2+2pq = 1\n$ ------------- Eq(A)

where

$p^2= \n$ frequency of the homozygous genotype (dominant)

$q^2= \n$ frequency of the homozygous genotype (recessive)

$pq= \n$ frequency of the heterozygous genotype (recessive)

Also, sum of the allele frequencies at the locus is equal to one.

Thus, $p + q = 1\n$ ------------- Eq(B)

Here frequency of recessive allele i.e $q = 30\n$ %

Substituting this in equation B, we get

$p + 0.3 = 1\np = 1-0.3\np= 0.7\n$

frequency of dominant allele i.e $q = 70\n$ %

Substituting the value of frequency of both dominant and recessive allele in equation A, we get

$(0.3^2) + (0.7^2) + 2pq = 1\npq = (1-0.3^2-0.7^2)/(2) \npq = (0.42)/(2) \npq = 0.21\n$

Thus, percent of the population that has skin pigment but also carries the recessive allele is $21\n$ percent

The correct answer will be 42%

What is a well-known issue with cross-sectional methodology?

Answers

Answer:

This methodology enables to measure simultaneously both the result and exposure in the group under study

Explanation:

A cross-sectional method is a type of scientific design based on observational data. The cross-sectional studies involve the use of diverse groups that differ in the variable investigated but share other features (for example, individuals with the same educational background, ethnicity, economic status, etc). This class of studies is generally used in developmental psychology.

What does the presence of these coral fossils suggest about the location of North America 370 million years ago?

Answers

Answer:

These fossils indicate that North America must have had a much warmer (i.e a tropical environment 370 million years ago)

Explanation:

Corals are marine animals whose skeletons are easily fossilized and thus have an extensive fossil record. There are many fossils of extinct corals in North America. For example, Lophophyllum is a North American extinct genus of corals dated at 320 million to 290 million years ago (i.e., from the Late Carboniferous period). In general, corals live in warm seawater, and thereby their fossil records can be used as indicators of environmental conditions.

The coral fossils' presence suggests that North America was located near the equator 370 million years ago, within the subtropical climate zones where corals thrive the most.

These seasonal changes in density create growth rings, similar to those found on trees. Scientists can use these rings and other features to determine the climatic conditions during the growing season of the coral.

By comparing the soil and plant and animal evidence at a site, scientists can get a general idea of what the environment was like in the past. By comparing living plant and animal evidence to these ancient remains, scientists can get an idea of what the environments were like.

When does oxyhemoglobin form during respiration? Group of answer choices during internal respiration immediately after carbon dioxide enters the blood when the chloride shift occurs during external respiration

Answers

Answer:

during external respiration

Explanation:

Oxyhemoglobin is a type of hemoglobin carrying oxygen which is bright red in color. In the blood, it's major function is to carry oxygen molecules throughout the body.

Oxyhemoglobin is formed during external respiration. External respiration also known as breathing occurs in the lung. During external respiration, there is an exchange of oxygen and carbon-dioxide between the cells of the body and blood vessels. During breathing, oxygen diffuses into the blood, the oxygen then binds with heme in the hemoglobin found in erythrocytes to form oxyhemoglobin.

Answer:

during external respiration

Explanation:

Oxyhemoglobin is a protein formed when hemoglobin is combined with an oxygen molecule during lung respiration, also called external respiration. Its function is to transport oxygen throughout the body.

External breathing is performed when we breathe in oxygen into the body. This oxygen will be used for cells to perform cellular respiration that will be responsible for exhaling carbon dioxide out of our body.
