The human eye is filled with a clear fluid called the aqueous humor. The production, flow, and drainage of this fluid is an active and continuous process which keeps the healthy eye at an intraocular pressure of about 15 mmHg. If the drainage becomes obstructed, fluid accumulates in the eye resulting in an increase of this pressure to the 25 to 50 mmHg range and the clinical onset of glaucoma. What is the pressure of 30 mmHg expressed in units of psi (pounds per square inch)

Answers

Answer:

The pressure will be "0.579 psi".

Explanation:

The given value is:

Hg,

= 30 mm

Density of mercury (Pm),

= 13600 kg/m³

As we know,

1 psi = 6895 N/m²

Now,

The pressure will be:

=  [tex]30 \ mm \ of \ Hg[/tex]

=  [tex]30\times 10^{-3}\times Pm\times g[/tex]

On substituting the given values, we get

=  [tex]30\times 10^{-3}\times 13600\times 9.8[/tex]

=  [tex]3,998,400\times 10^{-3}[/tex]

=  [tex]3,998.4 \ N/m^2[/tex]

So,

The pressure of 30 mm of Hg will be:

=  [tex]\frac{3,998.4}{6895}[/tex]

=  [tex]0.579 \ psi[/tex]

In grapes, the wild-type DND1 gene confers resistance to attain viruses, and strains are susceptible to viruses. The EDS1 gene confers resistance to powdery mildew, a type of fungal infection. The genes are linked, eight map units apart on chromosome 17. A third gene, IR 1. imparts resistance to certain lepidopteran leafminers and is 10 map units from EDS1 and 18 map units from UNDI The abserved double crossover rate is 0.3%. What is the interference?
a. 37.5%
b. 25.%
c. 62.5%
d. 75%

Answers

Answer:

I = 62.5%

Explanation:

Available data:

the wild-type DND1 gene confers resistance to attain viruses. Strains are susceptible to virusesThe EDS1 gene confers resistance to powdery mildew, a type of fungal infection The genes are linked, eight map units apart on chromosomeA third gene, IR 1. imparts resistance to certain lepidopteran leafminers and is 10 map units from EDS1 and 18 map units from DNDIThe observed double crossover rate is 0.3%

According to this information, we can picture the position of each gene in the chromosome

---DND1----------------------EDS1-----------------------------------IR1---

       ║---------- 8MU---------║------------------10MU-------------║

       ║------------------------------18MU------------------------------║

The map unit is the distance between the pair of genes for which one of every 100 meiotic products results in a recombinant product.

1% of recombinations = 1 map unit = 1cM. The maximum recombination frequency is always 50%.

So, if we know the distances between genes, we know their recombination percentages.

DND1-EDS1 = 8 MU = 8% recombinationEDSI-IR1 = 10 MU = 10% recombination

To calculate interference, first, we need to know the coefficient of coincidence, CC.    

CC= observed double recombinant frequency/expected double recombinant frequency

Note:

observed double recombinant frequency=total number of observed double recombinant individuals/total number of individuals expected double recombinant frequency: recombination frequency in region I x recombination frequency in region II.

CC= (0.003)/(0.08 x 0.1)

CC=0.003/0.008

CC=0.375

CC = 37.5%

The coefficient of interference, I, is complementary with CC.

I = 1 - CC

I = 1 - 0.375

I = 0.625

I = 62.5%

At a deep sea whale fall, the Atlantic hagfish, the crustaceans, and the sand make up which of the following?

Answers

Answer:

I would say part of an ecosystem and community.

Explanation:

An ecosystem is a biological community of interacting organisms and their physical environment .In the bottom of the sea,there are already many animals living here and when the whale fall appears at the bottom of the ocean it becomes apart of the ecosystem as it provides them with food.

This is because when a whale dies, its body often falls to the seafloor. The whale's body then becomes food and shelter for organisms in the deep sea. This is called a whale fall. A deep-sea whale  fall might support 200 different species for as long as 10 years! Larger species, such as Atlantic hagfish, are the first to arrive to feed  on the whale flesh. Later, smaller species of snails and crustaceans come to eat the remaining flesh. Worms burrow into the sand beneath  the whale body, and bacteria feed on the whale bones.

Answer:

Part of an ecosystem

Explanation:

The Atlantic hagfish and the crustaceans are living organisms. The sand is a nonliving part of the environment. An ecosystem is made up of living organisms and the nonliving parts of their environment. So, the Atlantic hagfish, the crustaceans, and the sand make up part of an ecosystem.

A six-week fitness program was designed to decrease the time it takes retired individuals to walk one mile. At the beginning of the program, 20 randomly selected retired individuals were invited to participate, and their times to walk a mile were recorded. After the six-week program, their times to walk a mile were again recorded. Most participants saw little to no improvement in their times to walk one mile; however, a few participants saw drastic improvements in their times to walk one mile. The program director would like to perform a hypothesis test to determine if the program reduces the mean time for retired individuals to walk a mile. Which of the following statements is true? a. Because there are 40 observations in total, the sample size is large enough to assume that the sampling distribution of the sample mean differences is approximately normal. b. Because the walk times before and after the program are paired, a hypothesis test is not appropriate. c. The sampling distribution of sample means can be assumed to be approximately normal because the distribution of the sample data is not skewed. d. Because the sample size of 20 is less than 30 and the improvements in walk times in the sample data appear to be skewed, the distribution of sample means should not be assumed to be approximately normal. e. Because the program recruited only retired individuals, the distribution of sample means should not be assumed to be approximately normal.
