Answer:
D / D / D / B / C
Explanation:
I just took the quick check myself, got all of them right :)
1 ) Top predators do not increase the number of prey, neither do they create imbalance or increase the food for other predator species. This is common knowledge, so ruling those out you are left with D. As they do in fact maintain the rest of the food chains populations.
2) A top predator in the ocean is a shark. Of course some might mistake a small whale to be a top predator, but sharks are actually known to hunt whales- the small ones anyway. A sea lion fish or a bird wouldn't exactly be a candidate for the top of the food chain either.
3) During seasonal flooding, to an area such as a river, water gets added to the existing pool, and many biotics and abiotics take this to their advantage. As a result- biodiversity actually increases during these times, but once season flooding is over it goes back to being the same.
4) The impact difference of seasonal flooding from damming a river is actually quite big. Seasonal flooding is.. well.. seasonal.. while damming for the most part is permanent, or will be there for much longer time span than season flooding is. Seasonal flooding increases biodiversity, but damming does not. This is becuase of the long term increase of water, the environment has to readapt, as plants that were once there drowned, and the known species most likely ran off to find better environment. Here it takes a while but eventually new abiotic and biotic species adapt and reclaim the dammed area of the environment.
5) Yes, a long term increase in the average temperature would disturb the ecosystem. Even if it's for a little bit, it's still something the environment wouldn't be used to, meaning the plants and animals there would have to learn to adapt for the time being- even if its temporary.
1: It maintains other populations
2: A shark
3: The biodiversity of the area increases
4: Seasonal flooding does not impact biodiversity for as long term as damming.
5: Yes, because such a change could have a large-scale impact on wildlife.

what happens to carbon dioxide molecules in the body cells?
Answer:
Carbon dioxide can be transported through the blood via three methods. It is dissolved directly in the blood, bound to plasma proteins or hemoglobin, or converted into bicarbonate. The majority of carbon dioxide is transported as part of the bicarbonate system. Carbon dioxide diffuses into red blood cells.

what is the molar mass of Br2 in grams
Answer:
159.808 g/mol
Explanation:
Br itself is 79.904 g/mol. So multiply it by two.
The molar mass of [tex]Br_{2}[/tex] is approximately 159.808 grams per mole.
When calculating the molar mass of [tex]Br_{2}[/tex], also known as diatomic bromine, the atomic masses of the two bromine atoms (Br) found in the molecule are added together.
Bromine (Br) has a mass of roughly 79.904 grammes per mole according to its atomic weight.
Because of this, the molar mass of [tex]Br_{2}[/tex] is calculated as follows: 2 times 79.904 g/mol = 159.808 g/mol
As a result, the amount of grammes that constitute one mole of [tex]Br_{2}[/tex] is roughly 159.808.

which of the following does mitochondrion undergo to provide energy for the cells?
Answer:oxygen
Explanation:”Quoted from somewhere”
Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. ... NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP). In ATP the energy is stored in the form of chemical bonds.
Answer:
Mitochondria: the energy converters
Explanation:
Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria.
The graph models the linear relationship between the water level of the river in feet and number of days the water level measured. Which function can be used to find y, the water level of the river after x days
Answer:
option 4, y=1/4x+16
Explanation:
to solve this you must find the slope and the y intercept.
slope is rise/run, and equal to 2/8 or 1/4
then, the find the y intercept, find where the line crosses the y axis. Here it is 16.
finally you plug these answers into the slope intercept form, y=mx+b. In this form, m= slope, x=days, and b= y intercept.
after you plug in your answers you are left with y=1/4x+16.

the chromatin condenses
into visible chromosomes
Answer: DNA and proteins contained in the nucleus, known as chromatin, condenses. ... The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes. Chromosomes are made of a single piece of DNA that is highly organized.During prophase, chromatin condenses into chromosomes, and the nuclear envelope, or membrane, breaks down. In animal cells, the centrioles near the nucleus begin to separate and move to opposite poles (sides) of the cell. ... The spindle starts to form during prophase of mitosis

Stalactites: Grow toward the cave floor.
Stalagmites: Grow toward the cave ceiling.
Swallow hole: A cave that has collapsed because of gravity.
Sinkhole: Where a stream disappears into the ground.
What are Stalactites?Mineral deposits known as stalagmites and stalactites are frequently seen in caves. The pointy, downward-pointing minerals that fall from the caves' roofs give rise to the stalactites.
On the other hand, stalagmites are created when minerals that fall from the roof are deposited on the ground afterward.

How is the age of the earth used as evidence of evolution?
Answer:
Explanation:
All radiometric evidence points to the age of the Earth as about 4.54 billion years old. The old age of the Earth is evidence for evolution, a change in the genetic makeup of a population over time.
Answer:
The age of the earth can be used as evidence of evolution because it withholds the past that we are capable of uncovering bit by bit. We excavate fossils buried in the ground which we use accordingly. The fossil record reveals that the deeper you go, the farther back in history you unearth. This is known as the Law of Superposition. With these fossils, we can compare and contrast the anatomy of closely related organisms and possibly uncover vestigial structures. All of which is evidence that evolution has taken place.

What is the function of the surface protein on the influenza virus?
Answer:
A virus surface proteins are organized to help penetrate host mucus.
Explanation:
The surface of viruses includes many copies of one type of protein that binds, or adsorbs, specifically to multiple copies of a receptor protein on a host cell.
The surface protein of influenza virus, hemagglutinin, helps the virus attach and enter host cells.
What are surface proteins?The surface protein on the influenza virus is called hemagglutinin (HA) and it plays a critical role in the virus' ability to infect host cells. HA is a glycoprotein that protrudes from the surface of the virus and binds to specific receptors on the surface of host cells, particularly in the respiratory tract.
This allows the virus to enter the host cell and hijack its machinery to replicate and produce more virus particles. The HA protein also enables the virus to evade the immune system by constantly changing its structure through a process called antigenic drift, which prevents recognition by the host's antibodies.
The importance of the HA protein makes it a prime target for the development of vaccines and antiviral drugs against influenza.
