The correct answer for this question is (D) It can proceed in the dark.

Calvin cycle is named after Melvin C. Calvin, who won a Nobel prize in chemistry for finding it in 1961. Calvin cycle take place in chloroplasts during photosynthesis and it is a <u>light-independent reaction so also called as dark reaction.</u>

The Calvin cycle proceeds in three stages:

1. Carboxylation, during which CO2 combines with ribulose-1,5- bisphosphate

2. Reduction, during which carbohydrate is formed at the expense of photochemically made ATP and NADPH

3. Regeneration during which the CO2 acceptor ribulose-1,5- bisphosphate is formed again so that the cycle continues.

You want to estimate the number of canvas backs (a type of duck) at the Sacramento Wildlife Refuge. In two days you capture 200
Vsevolod [243]

Answer:

Option A 400 individuals

Explanation:

Using this formula, we can estimate the population size of the canvas backs as this is a capture-recapture method.

N = (MxC) / R

Where N = estimated Number of individuals in the population

M = number of individuals captured and Marked = 200

C = total number Captured the second time (with and without a mark) = 200 and

R= number of individuals Recaptured (those with a mark) = 100

Thus, we have

N = (MxC) / R

= (200 x 200) / 100

= (40,000) / 100

= 400 individuals.

Based on the graph the region expected to have the least population growth will be Australia.

<h3>Graphical illustrations</h3>

Looking at the given graph the population size of each region starts at a lower point and ends at a higher point on the graph between the years 1950 and 2050.

The change in the population also varies depending on the scale on the y-axis. Australia has the lowest scale which lies between somewhere above 10 and 50.

Contrast what happens to thermal energy in evaporation and condensation
Alex17521 [72]
Answer - Will try to Answer in simplest form with Reasoning. Since no one responded.

1.Solar-Thermal energy. For example the sun radiates thermal energy aka heat which then turns Liquid aka Water in gas molecules because they are escaping. (Evaporation) 

2. Condensation happens when the water molecule vapor clump together before thermal energy can be separated by it. Such as the clouds which they form tiny vapor/mist. Thats why when your on a plane and when you hit thru that cloud at hundreds of mph. Your hitting water molecules lol.
