1. If the ecosystem is balanced, which populations should be the largest? Which should be the smallest?
2. Why can the wolf be considered both a secondary consumer and a tertiary consumer?
3. If the original amount of energy found in the producer trophic level is 100 kcal how much is passed on to the primary consumer trophic level? How does this amount limit the number of members in the next higher level?
4. Analyze what would happen to this ecosystem if one of the primary consumers was removed from the ecosystem? What would happen if a new tertiary consumer such as a mountain lion came into the ecosystem? Describe how each level would be affected if each of these changes occurred.
Answer:
1. producers are the largest and consumers are the least
2. because wolves feed on both primary and secondary consumers
3. Only 10% of energy from each trophic level is passed on to the next; therefore, the energy passed to the primary consumer will be only 10 kcal.
4. disturbe,as we know that secondary consumers feed on primary consumers so if there is no primary consumers then all secondary consumers will die similarly all tertiary consumers will also die and life would be finish on the earth.
if a new tertiary consumer came into the ecosystem then it will create a problem as the number of primary and secondary consumer are same but the tertiary consumer are more so they will get less food and hence die

What happens to a CO2 molecule when an infrared wave hits it?
The energy from the photon causes the CO2 molecule to vibrate. Some time later, the molecule gives up this extra energy by emitting another infrared photon. Once the extra energy has been removed by the emitted photon, the carbon dioxide molecule stops vibrating.

Which of the following is not a function of the skeletal system?
A.
provides a framework for the body
B.
provides protection for internal organs
C.
movement of bones
D.
production of new blood cells
Answer:
C
Explanation:
The skeleton relies upon the contraction and relaxation of muscles which are attached to bone in order to move. The muscular system is made up of three types of muscle, one of which is responsible for the movement of bone. To add to the confusion, the relationship between both muscles and bones is often lumped together as the musculoskeletal system, but to be sure, they are unique in their own ways.
In summary, bones can't move on their own, and therefore movement cannot be the skeletal system's function.
Which blood cell is most abundant?
Puffins live in the Arctic. Penguins live in the Antarctic. Suggest reasons why puffins and penguins are both similar and different
Answer:
Puffins are not actually penguins! They are birds that look similar, but are not the same species. Puffins belong to a family of birds called Alcidae, while penguins belong to the family Spheniscidae; their wings evolved to support different functions.

Why is it important to have range of tools that can measure all parts of the electromagnetic spectrum
This tiny slice of the universe, speckled with galaxies near and far, tells the story of galaxy evolution over cosmic time Among the 10,000 or so galaxies
pictured here are newborns, adolescents, adults and retirees Like looking through a vast collection of family photos, astronomers are poring over this
comprehensive image to see how galaxies grew up, matured, and aged
This portrait of our universe's history is called the Hubble Ultra Deep Field (or HUDF). It is a minuscule patch of sky first targeted by the Hubble Space
Telescope in 2002 and revisited over and over again since then. This version of the HUDF is extra special though It combines observations of the field
taken with Hubble's Advanced Camera for Surveys and the Wide Field Camera 3 from 2002 to 2012, providing one of the farthest views into the universe
we've ever seen Plus, it includes light not just from the visible part of the spectrum but from the invisible) infrared and ultraviolet ranges, too, giving us
different details of the story of how galaxies came to be
Infrared light lets us see the universe's youngest galaxies. These galaxies lie far far away from us, and as their light travels across the universe, it gets
stretched by the expansion of space Wavelengths of visible light grow longer becoming infrared light by the time it reaches us Combining Hubble's
observations of the HUDF in visible and infrared light a team of astronomers led by Garth Illingworth of the University of California identified more than
5,500 galaxies in a central portion of the field some so faint that they are just one ten-billionth the brightness of what the human eye can see Another
team headed by Richard Ellis of the California Institute of Technology (Caltech) used Hubble's infrared observations to find galaxies more than 13 billion
light-years away, when the universe was only about 400 million years old - or about three percent of its present age
Alternatively, to understand slightly older growing galaxies that are not so far away, observing in ultraviolet light is best The hottest and youngest stars
give off huge amounts of ultraviolet light making them easy to spot at those wavelengths of light Most recently, a team of astronomers led by Harry
Teplitz of Caltech used the ultraviolet-sensing abilities of Hubble's Wide Field Camera 3 to add the ultraviolet piece to this view of the HUDF With this
part of the galaxy evolution picture in hand, astronomers are investigating how galaxies grew through bursts of star formation and exactly where when
and how many stars formed over time
Because our atmosphere blocks or absorbs most infrared and ultraviolet light that reaches Earth only a telescope in space, like Hubble, can provide
such insights into the history of galaxies Without both infrared and ultraviolet light, the tale is incomplete.
Answer:
the inly question i understood ::::: Why is it important to have range of tools that can measure all parts of the electromagnetic spectrum
ans
Because the electromagnetic spectrum comprises different types of electromagnetic radiation (radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays), all of which have different wavelengths and require different tools to measure them.

Explanation:
Describe the ways mutations can affect DNA and chromosomes.
The mutation affects DNA and chromosomes by changes in the sequence of DNA or changes in the gene present on the chromosome.
What is mutation?The mutation is a sudden change in the structure of chromosomes or DNA. The smaller mutation affects the nucleotide base in DNA, while the larger mutation affects the genes present on the chromosomes.
The substance which causes mutation is known as mutagens. Mutation can cause problems in growth and development and affects the functioning of the body. When changes occur in chromosomes or DNA, they cause changes in the protein. Due to this, a different kind of protein is produced.
The mutation is caused by the insertion, duplication, deletion, and substitutions of a DNA sequence. Thus, mutation can affect DNA and chromosome in many ways.

what is a cell organelle that has the same function as the urinary bladder?
The cell organelle that has the same function as the urinary bladder is the lysosome.
What are lysosomes?This is a spherical sac-shaped cell organelle surrounded by a single membrane. (Unlike chloroplasts and mitochondrial membranes, which have two membranes.)
It contains hydrolytic digestive enzymes, which split molecules by the addition of water molecules. Autolysis/autophagy, which is the automatic discharge of digestive enzymes in a contained cell that destroys the entire cell, separates the digestive enzymes from other cell organelles.
Plant and animal cells both include lysosomes. The lysosome degrades or eliminates worn-out or damaged organelles. Waste management is something that serves the same purpose.
Therefore, the lysosome is a cell organelle that performs the same job as the urine bladder.

How many reactions that occur in kreb cycle transfer electrons from substrate to an electron acccepting enzyme
Answer:
Four reactions that occur in kreb cycle transfer electrons from substrate to an electron accepting enzyme.
Explanation:
There is four such a response in which electron is transported from substrate to electron-allowing enzyme. In three of those, NAD+ is decreased to NADH and in one FAD decreases to FADH2. The TCA cycle is likewise recognized as the Krebs cycle after the signature of English biochemist Hans Kreb who illustrated the pathway in the 1930s.
