How can we use science and math to develop a cost-benefit
analysis to help manage natural resources?

Answers


Cost–benefit analysis (CBA), also known as benefit–cost analysis, is rooted in applied welfare economics. It is a way of organizing and analyzing data as an aid to thinking. It provides a set of procedures for comparing benefits and costs and is traditionally associated with government intervention and with the evaluation of government action and government projects. The underlying rationale for CBA is rational choice; that is, a rational agent will weigh the costs and benefits of any proposed activity and will only undertake the activity if the benefits exceed the costs

Two pea plants heterozygous for the characters of pod color and pod shape are crossed. Assume that G allele stands for green pod color, g allele−for yellow pod color, I allele−for inflated pod shape, and i allele−for constricted pod shape. Complete the Punnett square for this cross.

Answers

Answer:

Please find the punnet square in the attachment section

Explanation:

This question involves two different genes; one coding for pod color and the other for pod shape. The allele for green pod color (G) is dominant over the allele for yellow pod color (g) while the allele for inflated pod shape (I) is dominant over the allele for constricted pod shape (i).

According to this question, two pea plants heterozygous for both of the characters or traits are crossed i.e. GgIi × GgIi. Each heterozygous parent will produce the following possible gametes:

GgIi - GI, Gi, gI and gi.

Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

- Green, inflated pods (G_I_) = 9

- Green, constricted pods (G_ii) = 3

- Yellow, inflated pods (ggI_) = 3

- Yellow, constricted pods (ggii) = 1

A consistent response in many organisms to changing environmental temperatures is the restructuring of cellular membranes.In some fish, phosphatidylethanolamine (PE) in the liver microsomal lipid membrane contains predominantly docosahexaenoic acid, 22:6 at C-2 of the glycerol-3-phosphate backbone and then either a saturated or monounsaturated fatty acyl group at C-1. Which of the following statements are False?

a. At 10 degrees Centigrade a lower percentage of PE molecules contain saturated fatty acyl groups at C-1 when compared to fish acclimatized at 30 degrees Centigrade.
b. At 10 degrees Centigrade a higher percentage of PE molecules contain saturated fatty acyl groups at C-1 when compared to fish acclimatized at 30 degrees Centigrade.
Ñ. At 30 degrees Centigrade a lower percentage of PE molecules had monounsaturated acyl groups at C-1 compared to that observed at 10 degrees Centigrade.
d. At 30 degrees Centigrade a higher percentage of PE molecules had monounsaturated acyl groups at C-1 compared to that observed at 10 degrees Centigrade.
e. The purpose of membrane restructuring with a change in temperature is to maintain fluidity of the membrane.

Answers

Answer:

The false statements are :

b. At 10 degrees Centigrade a higher percentage of PE molecules contain saturated fatty acyl groups at C-1 when compared to fish acclimatized at 30 degrees Centigrade.

d. At 30 degrees Centigrade a higher percentage of PE molecules had monounsaturated acyl groups at C-1 compared to that observed at 10 degrees Centigrade.

Explanation:

The false statements are :

b. At 10 degrees Centigrade a higher percentage of PE molecules contain saturated fatty acyl groups at C-1 when compared to fish acclimatized at 30 degrees Centigrade.

d. At 30 degrees Centigrade a higher percentage of PE molecules had monounsaturated acyl groups at C-1 compared to that observed at 10 degrees Centigrade.

Reason -

When temperature decreases,  the proportion of unsaturated fatty acids increases and saturated fatty acids decreases that also decreases the fluidity of the membrane and thereby make it stiff.

When temperature increases, the proportion of unsaturated fatty acids decreases and saturated fatty acids increases that makes the cell membrane more fluidic.

So, the temperature changes restructures the membrane with respect to fluidity of membrane.

Therefore,

At 10° Celsius, at C-1 of glycerol, the proportion of unsaturated fatty acids increases and saturated fatty acids decreases.

At 30° Celsius, the proportion of unsaturated fatty acid decreases and saturated fatty acid increases.

C) Investigators say that the suspect must be of a certain minority because that is who usually commits the crime in their precinct.
d) Investigators look for all the people leaving the crime scene to see if they are possible suspects.

Answers

Answer:

C) Investigators say that the suspect must be of a certain minority because that is who usually commits the crime in their precinct.

Explanation:

Cultural bias is the action where by someone holds a bias about a particular group of people or ethnicity due to the negative information which he or she had been feed with while growing up.

For example, when someone believes that, all crimes committed in America is done by African American people is a typical example of cultural bias. In the scenario given above, for the investigator to believe that, the suspect to be a certain minority rather than having an open view that it could have been anyone shows cultural bias and profiling of the investigators.

PLEASE HELP! huntington’s disease (HD) is prevalent South Africa. Most of the families with HD have Dutch or British ancestry, which suggests they inherited the European HD allele. HD is believed to have first arrived in South Africa more than 300 years ago when Dutch colonists settled into the Western Cape in the 1600s. Thus, the prevalence of HD in South Africa is the result of the founder effect.

Mutations in the HTT gene cause Huntington’s disease. The HTT gene provides instructions for making a protein called huntintin. This protein plays a role in nerve cells in the brain. The HTT mutation that causes HD involves a DNA segment known as a CAG trinucleotide repeat. This segment is made up of a series of three DNA building blocks that appear multiple times in a row. Normally, the CAG segment is repeated 10 to 35 times within the gene. In people with HD, the CAG segment is repeated 36 to more than 120 times. An increase in the size of the CAG segment leads to the production of an abnormally long version of the huntintin protein. This causes the dysfunction and eventual death of neurons in certain areas of the brain. The more repeats, the more serious the disease is.

HD is inherited in an autosomal dominant pattern. There is both an adult onset (after reproductive age) and a juvenile onset pattern. People with adult onset typically have 40 to 50 repeats, while people with the juvenile form tend to have more than 60 repeats. Individuals who have 27 to 35 repeats do not develop HD, but they are at risk of having children who will develop the disorder. As the gene is passed on to offspring, the size of the repeat may lengthen into the range associated with HD.

Predict what will happen to the allele frequencies for Huntington’s disease in South Africa if there were a new mutation to the HTT gene that causes a reduction to the CAG trinucleotide repeat. Justify your prediction with evidence. Your response should include links to the sources of information gathered.

Answers

Answer:

If there were a new mutation to the HTT gene that causes a reduction to the CAG trinucleotide repeat, the allele frequency for Huntington's disease would decrease in South Africa. HD is caused by too many repeats of the CAG segment causing an abnormally long version of the huntintin protein which becomes deadly. so if the number of repeats is reduced then the person is more likely to not have Huntington's disease. If they do still develop Huntington's disease, it will be more likely to be adult onset and they will still have an opportunity to reproduce offspring which may carry the trait for reduced CAG.

A population of raccoons is thought to be in Hardy-Weinberg equilibrium for a tail-length gene. The frequency of the dominant allele (long tails) is 0.8. When a certain forest was surveyed, the scientist was able to tag 25 animals, which were all long-tailed. Does the lack of short-tailed animals suggest that the population is out of Hardy-Weinberg equilibrium in this forest?
A. Yes, because the survey shows 100% AA individuals, so the short tils must have been selected against.
B. No, because you would only expect 4 of the surveyed racoons to be short-tailed, so they may have been missed by chance.
C. Yes, because 20% of the surveyed raccoons should have been short-tailed.

E. Germ Layer- Coelomate

Explanation:

Coelom is a fluid filled body cavity which stores food, blood like fluid in it in some animals.

Those organisms which do not possess the body cavity or coelom they are called as acoelomate. Example, Platyhelminths

Those animals which have a body cavity derive from the germinal layers ectoderm, endoderm, and mesoderm are coelomate. Example, Annelids

Those animals which have scattered pouches which are not lined by all germinal layers instead one mesoderm will not be able to form coelom. These are called as pseudocoelomate. For example, Nematodes.
