1. Which of the following describes the amount of organic material that is available for transfer to the next trophic level afte

r subtracting material used for respiration?
-Gross Primary productivity
-Biomass
-Net Primary productivity
0r
-Primary productivity

2. Suppose a plant is eaten by a mouse, the mouse is consumed by a snake, and the snake is in turn consumed by a hawk. What could be assumed about the level of available organic matter in the mouse versus the plant?
-There will be less organic matter available.
-There will be more organic matter available.
-Organic matter does not transfer between the plant and the mouse.
0r
-They both have the same amount of organic matter.

3. How does biomass change from lower to higher trophic levels?
-It fluctuates.
-It increases.
-It decreases.
0r
-It stays the same.

4. The incomplete burning of _____ in gasoline is known to create black carbon and contribute to global warming.
-ethanol
-methane
-carbon
0r
-carbon dioxide

5. Why are there less secondary consumers in an ecosystem than producers?
-Around 90% of energy from one trophic level to the next is available.
-There is less land to use for habitat after the producers grow.
-More tertiary consumers will eat secondary consumers over producers.
0r
-There isn’t enough energy available to support more secondary consumers.

Answer:

1C-Biomass 2D There will be less organic matter available. a

Explanation:

Biomass is the material that is eaten by a creature that is eaten by another creature which is eaten by the tetitary creature.

there is less organic matter avaliable once the creature eats and then is eaten

It decreases

What is the best choice for a blank when calibrating the spectrophotometer when you will later measure the absorbance of beverag
ELEN [110]

When calibrating a spectrophotometer, measuring absorbance concurrently is the best option for a blank since it is proportional to the concentration.

Beer's law states that A = a b c, wherein there is the diffusion coefficient at a constant, b is the actual route length, & c is the concentration. Direct proportionality exists between b and c and absorbance.

Once the route length is doubled, incident light contacts double as many molecules in the solution. The consequence is a doubling of absorbance, which is equivalent to a doubling of molecule concentration.

There are two ways to detect chemicals using spectrum scanning. One approach involves turning the monochromator continuously with a stepping motor while gradually altering the wavelength connected to the output slit.

It is more practical to use diode array detectors. Up to a few hundred photodiodes may be incorporated into the chip that makes up this device.

How are proteins related to the cell membrane? DNA
Elanso [62]

Answer:

DNA carries the genetic information for making proteins. ... The base sequence determines amino acid sequence in protein. Messenger RNA (mRNA) is a molecule which carries a copy of the code from the DNA, in the nucleus, to a ribosome, where the protein is assembled from amino acids.
