Answer:

Explanation:

aerobic respiration equation

glucose+ oxygen -> carbob dioxide gas + water + energy

Answer:C

Explanation:

Psychometric scores for anxiety, depression, negative self, somatization, and hostility were combined into a single Global Severity Index (GSI). Global Severity Index was compared for 80 adolescents who were seen in the outpatient clinic for 7 different physical complaints (short stature, obesity, lack of weight gain, breast problems, genital problems, menstrual problems, and hirsutism). Report the degrees of freedom for the relevant F statistic in the numerator and the denominator. (Round your answers to the nearest whole number.)

Answers

Answer:

The correct answer is -

Numerator = 6

Denominator = 73

Explanation:

In F static test or table there are two sets of degrees of freedom: one for the numerator and one for the denominator. The degrees of freedom are equal to the number of observations minus one. Thus, if the sample size were 7 then the degree of freedom would be 7 minus 1

Numerator df = 7 - 1 = 6

Thus, the numerato would be - 6.

Denominator is calculated by subtracting the observation or variables from the total number of sample size.

Denominator df = 80- 7 = 73

In a study involving a cell-free translation system from coli, the polyribonucleotide AUGUUUUUUUUUUUU directs the synthesis of the oligopeptide fMet-Phe-Phe-Phe-Phe. In the presence of a new class of translation-targeting antibiotics that bind to the large ribosomal subunit, the ribosomal complex forms, the initiator tRNA binds the mRNA, the second tRNA enters the A site of the ribosome, but no peptide bonds form. Which of the following is a likely function of these new antibiotics?

a. Blocks peptidyl transferase activity
b. Inhibits tRNA aminoacyl synthetase function
c. Inhibits ribosomal translocation along the mRNA
d. Prevents anticodon base-pairing with the codon
e. Blocks binding of the Shine-Dalgarno box to the rRNA

Answers

Answer:

c. Inhibits ribosomal translocation along the mRNA.

Explanation:

Initiator tRNA is thought to bind directly to P-site of small ribosomal sub unit. These tRNA are positioned at P site and remain attached to tRNA located at this site. Initiation factor helps to mediate this event.

Explain how the villi are adapted to absorb glucose.

Answers

Answer:

The villi in the small intestine provide a large surface area with an extensive network of blood capillaries. This makes the villi well adapted to absorb the products of digestion by diffusion and active transport.

Villi have a large surface area adapted to absorb glucose

What is glucose?"Glucose is a simple sugar with the molecular formula C₆H₁₂O₆."It is a monosaccharide.Different enzymes are present in human body that converts polysaccharide and disaccharides into glucose.It is transported in human body through blood.What is surface area?"The area of an outer part or uppermost layer of something."What is villi?Villi is a finger like projection present in the lumen of small intestine.It has large surface area to absorb glucose.Just below the outer surface of villi, blood vessels lie that transports glucose.

Describe fluid exchange between capillaries and the interstitial fluid. Be sure to discuss the forces (pressure) that moves the fluid and the direction in which fluid moves. (4 points) In one to three sentences, describe the role of lymphatic system in this fluid exchange. (3 points) g

Answers

Answer:

Capillary exchange is the exchange of fluid from the capillaries into the interstitial fluid and vice versa. Diffusion, transcytosis, and bulk flow are three mechanisms that facilitate capillary exchange.

The blood plasma or interstitial fluid exerts a pressure of the fluid on the capillary walls known as Hydrostatic pressure. Osmotic pressure is a pressure exerted by proteins either in the blood plasma or interstitial fluid called oncotic pressure.

Lymphatic capillaries gather lymphatic fluid and regulate the pressure of interstitial fluid due to the forces of hydrostatic or oncotic pressure. An essential role of the lymphatic system is to return the fluid to the blood.

A. The production of dirt.B. The release of free nitrogen into the atmosphere.C. The release of sulfur dioxide into the atmosphere.D. The movement of air currents by convection cells.

The production of dirt is cause predominantly by living organisms

This production can be caused through emission of pollution in the form of air, water, soil, noise or e-waste.

What is Pollution?

Pollution is defined as the introduction of unwanted harmful elements in the form of release of gaseous toxic substances which result into polluting the environment.

These pollutants can be both natural and anthropogenic.

Natural pollutants are volcanic ash, river sediments

Anthropogenic pollutants are chemicals released from industries vehicular emission.

Majorly pollution are of four types- Air, Water, Soil and Noise. Recently another pollution in the form of e-waste is also prominent.

Effects of pollution on environment:

1. Biomagnification describes situations where toxins (such as heavy metals)  passes through trophic levels, becoming exponentially more concentrated in the process.

2. Carbon dioxide emissions cause ocean acidification, the ongoing decrease in the pH of the Earth's oceans as CO2 becomes dissolved.

3. The emission of greenhouse gases leads to global warming which affects ecosystems in many ways.

4. Nitrogen oxides are removed from the air by rain and affect the land which can change the species composition of ecosystems.

5. Smog and haze can reduce the amount of sunlight received by plants to carry out photosynthesis and leads to the production of tropospheric ozone which damages plants.

6. Sulfur dioxide and nitrogen oxides can cause acid rain which lowers the pH value of soil.

7. Organic pollution of watercourses can deplete oxygen levels and reduce species diversity.

Rest three options are majorly natural process.

Option B focuses on release of free nitrogen into atmosphere which is one of the important step of Nitrogen Cycle.

Option C focuses towards release of Sulfur Dioxide into atmosphere. This process is caused either naturally or anthropogenically. Thus cant blame solely the anthropogenic factor for its release.

Option C is the total natural process i.e. Climatological Process where air currents are regulated by Convection Cells and regulate based on different natural factors.

Question 19
How would the carbon cycle be influenced by an increase in aerobic respiration?

Answers

Answer:

Cellular respiration does not affect the carbon cycle but is part of the carbon cycle. The 2 carbon cycles. carbon ( C ) is taken up by the plants and trees in the form of carbon dioxide ( CO2 ). Plants converts this CO2 into organic compounds such as glucose ( C6H12O6 ).

Explanation:

Increase in aerobic respiration will lead to increase in the amount of CO2 released into to the atmosphere due to respiration.

Aerobic respiration occurs when oxygen is combined with glucose to yield carbon dioxide and water. This is one of the major ways through which carbon dioxide enters the carbon cycle.

Note that the carbon cycle shows the movement of carbon in nature. Increase in aerobic respiration means that more carbon will be introduced into the atmosphere as carbon dioxide.

At this point, the writer is considering adding the following sentence. Successful nerve impulse transmission depends not only on myelin sheaths, but also on the presence of ion pumps embedded in the cell membrane. Should the writer make this addition here?
A) Yes, because it describes how the presence of ion pumps is related to the functions of cholesterol.
B) Yes, because it supports the passage’s main argument with a second example of cholesterol’s potential adverse health effects.
C) No, because it identifies a relationship between the nervous system and ion pumps that has already been discussed.
D) No, because it interrupts the paragraph’s discussion of cholesterol’s functions with loosely related information.

Answers

Answer:

D) No, because it interrupts the paragraph’s discussion of cholesterol’s functions with loosely related information.

Explanation:

The passage was discussing the importance of cholesterol in nerve impulse transmission. Its presence in the myelin sheaths of nerve cells speeds up nerve impulse transmission. It will not be wise for the author to now bring in the relationship between nerve impulse transmission and ion pumps. This is because the main topic under discussion is cholesterol and its importance. The sentence should be continued with other importance of cholesterol and not ion pumps.
