The three methods of heat transfer include: conduction, convection, and radiation. It is through one of these processes of heat

transfer that the air temperature over water is warmer than the water over land during the winter months. You'll notice on the graph, that January (month 1) and February (month 2) water temperatures are about 20 degrees while the respective air temperatures are about 15 degrees. This is a 5 degree difference in temperature between the air and the water at the same geographical location. Which process do you believe to be the cause of the air temperature differences between land surfaces and a body of water? A) Heat goes directly from water to air through conduction. B) The heat of the ocean is being radiated into the air through the process of radiation. C) Cooler air is replaced by warmer air rising from the surface in the process of convection. D) Heat is transferred through the circulation of the water through the atmosphere in the process of convection.

Pseudomonas putida is used for fermentation of the lactose present in cheese whey. The bacteria are cultivated in a steady-state
fgiga [73]

Answer:

Explanation:

Given that:

The dilution rate D = 0.28 h⁻¹

The concentration of lactose in the feed S_o = 2.0 \ g/L

The effluent S = 0.10 g/L

Also;

Y_{X/S} = 0.45 g\  X/g  \ S , \\ \\  Y_{X/O2  }= 0.25 g  \ X/g  \ O2,  \\ \\

Saturation C* = 8 mg/l

To calculate the steady-state biomass, we use the formula:

X = Y_{X/S}(S_o-S_e) \\ \\ X = 0.45(2.0 -0.10) \ g/L \\ \\ X= 0.45 (1.9) \ g/L \\ \\  X = 0.855\ g/L \\ \\  X = 855 \ mg/L

The biomass is 0.855 g/L

For a steady-state condition, the oxygen uptake rate can be illustrated by using the formula:

q_{o_2}X =\dfrac{\mu_X}{Y_{X/O_2}}

where;

\mu = dilution rate (D)

Thus, the steady-state can be expressed as:

q_{o_2}X =\dfrac{D}{Y_{X/O_2}}

q_{o_2}X =\dfrac{0.28}{0.25}

q_{o_2}X =1.12 \ h^{-1}

The specific rate of oxygen consumption q_{o_2}X =1.12 \ h^{-1}

b)

In the fermentation medium, if the desired DO concentration C_L = 2 mg/L

Here, the oxygen transfer is regarded as the rate-limiting step.

As such, the oxygen transfer rate(OTR) is equivalent to the oxygen uptake rate.

In this scenario, let's determine the oxygen transfer coefficient (K_{La}) by using the formula:

OTR =  K_{La}(C^* - C_L)

where;

K_{La}= coefficient of oxygen transfer

C* = saturation

Since OTR = q_{O_2}X

q_{o2}X = K_{La}(C^*-C_L) \\\\ (1.12 )(855) = K_{La}(8-2) \\ \\  957.6 = K_La (6) \\ \\ K_{La}= \dfrac{957.6}{6} \\ \\ K_{La} = 159.6 \ h^{-1}

Thus, the oxygen transfer coefficient K_{La} = 159.6 h⁻¹

Why the solute can't move from higher concentration to lower concentration?
Basile [38]

Answer:

yes, so when the concentration of a solute is high, the concentration of water is lowered since there is more solute per water, less water per solute. Thus, when water moves from low concentrations of solute to high concentrations of solute, it moves from high concentrations of water to low concentrations of water.

Which phrese does not describe oceans near the equator
irina [24]

Low lightning does not describe oceans near the equator. thus option D is correct..Low tempretare, low salinty and low density are the other options which are not mention in question.

<h3>Which oceans are near the equator?</h3>

The Pacific, Atlantic, and Indian Oceans are all located along the equator.

Low lighting does not describe oceans near the water because they receive maximum sunlight in the daytime. As a result, the equator experiences significantly stronger sunshine than the north and south poles, which warms the water there.Low tempretare, low salinty and low density are phrase describe ocean near the equator.

How are Amino acids linked to become proteins?​
wlad13 [49]

Answer:

Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain.

Explanation:

Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.
