an agricultural biologist was evaluating two newly developed varieties of wheat as potential crops. in an experiment, seedlings were germinated on moist paper towels at 20c for 48 hours. oxygen consumption of the two day old seedlings was measured at different temeratures
Indirect metabolic rate measurements are made using oxygen uptake and carbon dioxide production. This works because food is metabolized by cells while they produce energy, water, and carbon dioxide through cellular respiration.
It was discovered that increasing temperature generally increased the rate of oxygen consumption and ammonia excretion. From 0.97 mg O2/g/hr at 30 degrees C to 2.2 mg O2/g/hr at 35 degrees C, it was discovered that oxygen consumption increased. The absolute O2 concentration and, consequently, the output of the O2 sensor, are temperature-dependent, just like barometric pressure. If the temperature correction is not used for relative measurements, the relative O2 concentration fluctuates while remaining constant at 20.95%.

Who should decide what types of energy sources should be developed?
Explanation:
Your mitochondria makes ATP. There are the lots of process that goes into making ATP.
an enzyme catalyzes the reaction a → b. the initial rate of the reaction was measured as a function of the concentration of a. the following data were obtained: a) What is the Km of the enzyme for the substrate A?b) What is the value of V0 when [A] = 43?c) What is the value of the y-intercept of the line?d) What is the value of the x-intercept of the line?
The Km can be determined by fitting data to the Michalis-Menten equation, V0 at [A]=43 needs more information, y-intercept is 1/Vmax, and x-intercept is -1/Km.
What are the Km, V0 at [A]=43, y-intercept, and x-intercept of the line obtained by fitting initial rate data of an enzyme catalyzed reaction to the Michalis-Menten equation?To determine the Km of the enzyme for substrate A, we need to plot the initial rate data as a function of substrate concentration and fit the data to the Michalis-Menten equation, which is given by:
V0 = Vmax [A] / (Km + [A])
where V0 is the initial rate of the reaction, Vmax is the maximum rate of the reaction, [A] is the concentration of substrate A, and Km is the Michalis-Menten constant.
By plotting the initial rate data and fitting the curve to the Michalis-Menten equation, we can estimate the value of Km.
Specifically, Km is equal to the substrate concentration at which the initial reaction rate is half of the maximum rate.
The value of V0 when [A] = 43 cannot be determined without additional information about the initial rate data.We need to know the specific values of V0 at different substrate concentrations to determine the rate of the reaction when [A] = 43.
The value of the y-intercept of the line corresponds to 1/Vmax, where Vmax is the maximum rate of the reaction. This is because when [A] is very high, the reaction rate approaches Vmax, and the Michaelis-Menten equation can be simplified to:V0 = Vmax
Therefore, the y-intercept of the line is equal to 1/Vmax.
The value of the x-intercept of the line corresponds to -1/Km. This is because when the initial rate is zero, the denominator of the Michalis-Menten equation is equal to Km, which can be rearranged to:[A] = Km / 1
Taking the reciprocal of both sides gives:
1/[A] = 1/Km
Therefore, the x-intercept of the line is equal to -1/Km.
The values of V0, Vmax, and Km cannot be calculated without the actual data.

The major lipids of plasma membranes. are called b. Phospholipids, which form a bilayer in the cell membrane.
What is the phospholipid bilayer in the cell membrane?
The phospholipid bilayer in the cell membrane is an arrangement of phospholipids in order to form biological barriers that allow the selective movement of substances across the internal medium of the cell and the surrounding environment.
A phospholipid is composed of a phosphate polar head and fatty acids that are located on the internal side of the cell membrane because it is hydrophobic (polar phosphate heads are in contact with surrounding water which stabilizes the cell membrane).
Therefore, with this data, we can see that the phospholipid bilayer in the cell membrane is arranged in the sense that the phosphate heads of these biomolecules are located on the outside and fatty acids inside.

This Venn diagram is being used to compare the characteristics of nonvascular and vascular plants.
Which characteristic is shared by the two plants, and can therefore be placed in the overlapping section?
have roots
perform photosynthesis
have xylem and phloem
produce seeds
Answer:
perform photosynthesis
The specific xylem and phloem tissues that vascular plants (tracheophytes) have for supporting and conducting water and food, respectively, set them apart from nonvascular bryophytes.Thus, option B is correct.
What best defines about nonvascular and vascular plants?The existence of chloroplasts and the green pigment chlorophyll, which enable plants to carry out photosynthesis, is the fundamental similarity between these two plant groupings. Due to their capacity to manufacture their own food, plants are now the main contributors to the ecosystem's production.
Tracheophytes are another name for vascular plants. Pteridophytes, gymnosperms, and angiosperms are among them.Nonvascular plants lack the specialized vascular system required to transmit water and nutrients. Examples of simple structures that are specialized for doing transportation are those found in algae and bryophytes.

Describe the general flow of energy through an ecosystem beginning with the Sun and going through a third order consumer.
Answer:
1) Autotrophs transform solar energy into chemical energy.
2) Herbivores and omnivores (primary consumers) eat producers, make use of some of the energy, making from it their biomass.
3) Following, carnivores or predators (secondary, tertiary, and other consumers) eat herbivores, using only 10% of the flowing energy.
4) Decomposers (last order in the chain) recycle all the dead organic material and make use of some of the stored energy.
Explanation:
Energy flow: From the whole quantity of energy that reaches the earth's surface, only 0.1 or 1% is absorbed by autotroph organisms or producers.
From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment.
Organisms that can use light, and turn it into organic matter according to their own needs are producers, and they are called autotrophic organisms. These organisms are by excellence all plants, algae, and bacteria that photosynthesize. Organisms that are incapable of producing their food are called heterotrophic. They depend on other organisms from the trophic chain such as plants or other animals to feed on, so they can get proteins and energy. In the trophic web, heterotrophic organisms occupy the first, second, or third consumer level, after producers. There are different types of heterotrophic animals: carnivorous, herbivorous, omnivorous, hematophagous, ichthyophagous, and etcetera. All of them depend on autotrophic organisms.
At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.
The progressive reduction of energy determines the number of trophic levels in the chain (4 or 5).
1) Autotrophs use water, CO2, and solar energy to produce O2 and glucose, by the process of photosynthesis and convert it into biomass. Producers transform solar energy into chemical energy.
2) Herbivores and omnivores (primary consumers) make use of some of this energy to survive, making from it their biomass. The rest of the energy is lost.
3) Following, carnivores or predators (secondary, tertiary, and other consumers) eat herbivores, using only 10% of the flowing energy. The rest of the energy is lost.
4) When different organisms die, decomposers (last order in the chain) recycle all the organic material and make use of some of the energy stored in their tissues. The rest is lost.
in state- of- the- art vacuum systems, pressures as low as 1.00 × 10−9 pa are being attained. calculate the number of molecules in a 1.00 m3 vessel at this pressure and a temperature of 27.0°c. a. 1.44×1021molecules b. 1.42×1011molecules c. 2.42×1021molecules d. 2.42×1011molecules e. 2.48×1012molecules
Using the ideal gas law equation, the number of molecules in a 1.00 m³ vessel at this pressure and a temperature of 27.0°C is 2.48 × 10^12 molecules. The answer is e. 2.48 × 10^12 molecules.
To calculate the number of molecules in a 1.00 m³ vessel at a pressure of 1.00 × 10−9 Pa and a temperature of 27.0°C, we can use the ideal gas law equation. The ideal gas law is given by PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature.
First, we need to convert the pressure to Pascals (Pa). 1 Pa is equal to 1 N/m2. Therefore, 1.00 × 10−9 Pa is equal to 1.00 × 10−9 N/m2.
Next, we need to convert the temperature to Kelvin (K). The temperature in Kelvin is equal to the temperature in Celsius plus 273.15. Therefore, 27.0°C + 273.15 = 300.15 K.
Now we can substitute the values into the ideal gas law equation:
(1.00 × 10−9 N/m2) * (1.00 m3) = n * (8.314 J/(mol·K)) * (300.15 K)
Simplifying the equation:
n = (1.00 × 10−9 N/m2 * 1.00 m3) / (8.314 J/(mol·K) * 300.15 K)
n ≈ 4.19 × 10^-11 mol
Finally, to calculate the number of molecules, we can use Avogadro's number, which is approximately 6.022 × 10^23 molecules/mol:
Number of molecules = (4.19 × 10^-11 mol) * (6.022 × 10^23 molecules/mol)
Number of molecules ≈ 2.52 × 10^13 molecules
Therefore, the answer is e. 2.48 × 10^12 molecules.

short-chain fatty acids such as butyrate are absorbed by the mammalian intestine and used as metabolic fuels. how many atp can be derived from the complete oxidation of butyrate?
About 29 ATPs are derived from the complete oxidation of butyrate. This comes from 1 FADH₂, 2acetyl CoA, and 1 NADH.
Fatty acids are considered the building units of fats. These fatty acids are nothing but a chain of hydrocarbons. They are also used to generate energy in the body. This metabolic process of energy generation from fatty acids is referred to as β-oxidation. One complete round of this oxidation helps to generate about 1 FADH₂, 1 acetyl CoA, and 1 NADH.
Butyrate is considered a short-chain fatty acid. It has only four carbons, and oxidation of this will result in the production of two acetyl coA in a single round. So the number of ATPs from FADH₂ is 2, NADH is 3, and 1 acetyl co A is 12. Then, the total ATP is 2+3+24=29 ATPs. The required answer is 29 ATPs.

When blood glucose levels are high, the pancreas secretes the hormone insulin, which causes the liver to remove excess glucose from the blood and to store it in the liver as ____________ . When this stored form of glucose is low, the liver converts ____________ from fats and amino acids to glucose molecules. Most pancreatic cells produce pancreatic juice, which contains ____________ , to help neutralize the stomach acid. Pancreatic amylase digests ____________ , trypsin digests protein, and lipase digests fat. The major functions of the liver include: removing or detoxifying harmful substances from the blood; storing glycogen, ____________ , and several vitamins; synthesizing many proteins found in the blood ____________ ; and regulating blood cholesterol. Another function of the liver is to produce bile, which is a yellowish-green color because it contains bilirubin, a breakdown product of ____________ . Bile also contains bile salts, which serve to emulsify ____________ in the small intestine.
Answer:
The correct answer is - small intestine; glucagon, glycogen; glycerol, sodium bicarbonate; starch, iron, plasma, hemoglobin; fats.
Explanation:
The digestive enzymes are released in the small intestine by pancreatic cell, the cluster of these pancreatic exocrine cells called pancreatic islets that release insulin and glucagon hormones for controlling blood sugar level.
Insulin stores the excess amount of blood glucose in the liver as glycogen and in the case of low sugar glycerol is converted to glucose from fats. Pancreatic juice contains sodium bicarbonate to regulate acidity and the amylase enzyme helps in digesting starch. The liver stores various nutritional substances such as vitamins and iron and others and release them in blood plasma.
