Answer:
A and B
Explanation:
1. Which of the following describes the amount of organic material that is available for transfer to the next trophic level after 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.
Net primary productivity is the amount of organic material that is available for transfer to the next trophic level after subtracting material used for respiration.
When a plant is eaten by a mouse, the mouse is consumed by a snake, and the snake is in turn consumed by a hawk. In this case, there will be less organic matter available.
Biomass change from lower to higher trophic levels by decreasing.
The incomplete burning of ethanol in gasoline is known to create black carbon and contribute to global warming.
There is less secondary consumers in an ecosystem than producers because there isn’t enough energy available to support more secondary consumers.
It should be noted that global warming brings about the increase in the temperature around the world.

Evaluate the evolutionary benefits of regulating an internal variable, such as body temperature, versus the cost.
Answer:
The benefits of being able to regulate the internal body temperature are many and it is considered a beneficial evolutionary character, since in this way the living organism is better maintained in relation to the environment, and it achieves better balance.
Reptiles cannot control their internal temperature, it depends on the external one, that is why to warm their body they need to be in the sun, and to cool down in the shade or in temperate places.
This is a little evolutionary characteristic since the environment is very changeable and the right or ideal temperature for the organism could not be controlled.
Explanation:
Faced with climatic catastrophes or extreme situations, living organisms cannot depend on the great climatic variants, in very cold situations one enters hypothermia and in very hot conditions the proteins are systematically denatured, entering a thermal shock.
explain the process of DNA extraction and gel electrophoresis
Answer:
The process of that same framework in question is defined below.
Explanation:
The DNA was indeed prepared by mixing with either a dye as well as a radioisotope which enables the gel to have been recognized. The specific filaments would then be differentiated from one another DNA electrophoresis. The procedure occurs with the injection including its completely separate genetic code into boreholes that have already been reduced either at the final moment including its gel pavement.
what happens to the chemical bonds during chemical reactions
Only answer if you know the answer
Answer:
B. A helicase enzyme unwinds the DNA molecule, then corresponding nucleotides are added to the separated original strand forming two separate semiconservative molecules
Explanation:
DNA Replication is an important phenomenon as far as cell division is concerned. It is the process whereby a DNA molecule doubles its content or forms two DNA molecules from one.
In the semi-conservative model of DNA replication, an enzyme called DNA helicase unwinds the double stranded DNA molecule into two single strands. The single strands are then used as template for DNA polymerase to synthesize another molecule of DNA. Hence, two separate DNA molecules comprising of one old strand and one new strand.

5. The lion researchers in the film have studied 20% of the park and identified 41 lions. (Show your
work/justify your answer for each section.)
a. The entire Gorongosa park is 4,000 km². Approximately how large (in km) is the portion of
the park that has been studied?
ASAP PLSS
Answer:
800 km²
Explanation:
If the researchers have studied 20% of the 4000 km² park, to find out how much of the park in km they have studied, all you have to do is find 20% of 4000.
4000 x .20 = 800
800 km² is your answer.
If the area of the entire Gorongosa park is 4,000 km². Among which, 20% of the park is already studied, it means 800 [tex]km^2[/tex].
What do you mean by the researcher?A researcher may be defined as a kind of person who significantly carries out academic or scientific research in order to find some unrevealed data and information.
According to the question,
The total area of Gorongosa park = Gorongosa park is 4,000 km²
The area which is already studied = 20%.
Now, you have to find the area that is already studied in km. So, you have to calculate the 20% of 4,000 km².
The area which is already studied = 4000 × .20 = 800 [tex]km^2[/tex].
Therefore, if the area of the entire Gorongosa park is 4,000 km². Among which, 20% of the park is already studied, it means 800 [tex]km^2[/tex].

The batteries in a flashlight are Dead and the flashlight no longer works. What happened to the energy that was in the battery
Answer:
See the answer below
Explanation:
When the batteries in a flashlight become dead and the flashlight no longer works, it means that the chemical energy present in the battery has been converted to electrical energy to power the touch and eventually got lost to the environment as heat.
In a typical flashlight that works with batteries, the chemical energy in the batteries is converted to electrical energy, and this powers the bulbs in the flashlight. Gradually, the electrical energy is converted to heat energy and this is lost to the environment by radiation. When all the energy is lost to heat, the batteries are said to be dead and the flashlight stops functioning.

Fish are considered carbon-based organism
Answer:
Its how you see it.
Explanation:
1.Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.
2.All life on earth can be thought of as "carbon-based." Just be careful about turning this around backwards. It is true that all living things contain carbon compounds... but the opposite is not true. Just because a certain material is referred to as organic does not mean it is or ever was alive.
A species of elm has winged-seeds. How would biologists explain how a species of elm with winged-seeds evolved from an ancestral elm species without winged-seeds
Answer:
In an ancestral elm species, mutations gave rise to the phenotypic trait "winged-seeds". Subsequently, selection favored elm plants with winged-seeds that diverged over time to become a separate species
Explanation:
A mutation is a genetic change in the DNA sequence. In general, mutations have a negative impact on the fitness of the individual (i.e., mutations are generally deleterious) and therefore they disappear from the population. However, there are situations where mutations are beneficial and confer an adaptive advantage, thereby increasing their frequency in the population. In this case, mutations associated with the formation of winged-seeds conferred an adaptive advantage (i.e., higher seed dispersal capacity) to individuals who had this phenotypic trait, thereby these individuals had more chances to reproduce and pass their genes to the next generation. Eventually, Elm plants with winged-seeds accumulated sufficient genetic differences to prevent interbreeding, leading to the formation of a separate species.
