EUTROPHICATION
Explanation:
Melting ice sheets increase the volume of water in the oceans and reduce the salinity of water. How would this affect:
a) sea animals in polar regions?
b) coastal areas already at sea level?
Answer:your answer is B
Explanation:
In the polar regions if the water goes onto shore it would freeze adding to the icy land and giving sea animals an advantage as all the sea animals would be at the to of the sea level giving a better attack on prey. as in Coastal area it would flood the area causing and flood.
predict the effect of reintroducing wolves into the park on the coyote, grass and raven populations.
Answer:
Wolves and coyotes will compete for resources and the coyote population will decrease and wolves might decrease from competition as well. The increase of predators (wolves and coyotes) will cause the raven population to go down. If the raven eat grass then the grass population will go up becuase more ravens are getting eaten= no one eating grass.
Explanation:
Answer:
The amount of grass increases. The amount of coyotes decrease. The amount of ravens increase.
Explanation:
Wolves and coyotes will compete for resources and the coyote population will decrease. The increase of dead deers caused by the increase of the wolf population will cause the raven population to increase and the amount of grass to increase.

think of it how you use chalk on a chalk board, its less friction using chalk instead lets say a marker on a white board.
While investigating applications of science knowledge, Willy learned that scientists have used genetic engineering techniques to attach insulin-producing genes to bacterial DNA. These bacteria produce large amounts of scarce human hormones. Scientists predict that hormones produced by bacteria will be inexpensive and will not cause allergic reactions. (SC.7.N.1.5) Scientists developed hormone-producing bacteria because they wanted to
Answer:
develop methodologies to increase the production of hormones for human use
Explanation:
Genetic engineering refers to the manipulation of an organism's genes by using recombinant DNA (rDNA) techniques in order to develop biotechnological and biomedical applications. For this purpose, genetically engineered bacteria carrying recombinant human genes can be used for producing human hormones. For example, recombinant human insulin can be produced by using Escherichia coli strains, and this hormone can then be purified as genetically engineered bacteria grow in order to treat diabetic patients. For this purpose, a bacterial plasmid (i.e., an independent fragment of circular bacterial DNA) is cut with restriction enzymes and then the human gene encoding the hormone of interest is inserted into the plasmid. Finally, the genetically modified plasmid may be readily transferred to the bacterial chromosome and thus increase the supply of the hormone of interest for its use by humans.

Volcanoes form most commonly in regions where one tectonic plate plunges beneath another tectonic plate. How does this process
lead to volcano formation?
OA. The plate plunging downward suddenly turns upward, breaking through the surface to form volcanoes.
OB. The plate plunging downward knocks loose part of the Earth's core, which rises up to form volcanoes at the surface.
OC. It causes strong earthquakes, which shake the ground upward into the shapes of volcanoes.
OD. It causes part of the overriding plate to melt into magma, which rises up to form volcanoes at the surface.
Answer:
OD is the correct answer
Answer:
The answer is
OD. It causes part of the overriding plate to melt into magma, which rises up to form volcanoes at the surface.

1. primary consumers
2. secondary consumers
3. producers
4. the sun
Answer:
The sun.

What percentage of the U.S. population has Rh+ blood?
Answer:
85% of the the U.S. population has Rh+ blood
Explanation:
Out of the total population of USA, nearly 15% of the individuals are having Rh negative blood.
The remaining population has Rh positive blood which is equal to 100-15%
or 85%.
Thus, 85% of the the U.S. population has Rh+ blood

Are the nitrogenous bases just free floating in the nucleus? If so..why are they just floating? And how are they made? Thank you :)
Answer:
No, they order in sequences of base pairs in DNA
Explanation:
As you know, there are four nucleotides: Adenine, Thiamine, Cytosine, and Guanine. Adenine and guanine are purines, and cytosine and guanine are pyrimidines. You might not know what that means, so just in case purines are longer and pyrimidines are shorter. Therefore, A pairs with T and C with G. These pairings, along with other structural enzymes, build strands of DNA in the nucleus. I hope that helped, if you have more questions just let me know.

Does light have an effect on carbon dioxide production by plants and animals?
(No Links!! type the answer)
Answer:
Light provides the energy for photosynthetic pig- ments to convert carbon dioxide (CO2) and water into sugars and oxygen. As light intensity increases – until a point – the amount of sugars increases and thus, more energy is available for plant growth and maintenance. ;)
What landscape feature contributes to the dryness of deserts?
O Desert canyons collect all water and funnel it out of the desert.
O Mountains block the winds that bring rain clouds.
O The open, flat areas of a desert prevent clouds from forming.
O Desert lakes absorb all the water.
Answer:
Deserts are areas that receive very little precipitation. ... Others are dry expanses of rock, sand, or salt flats. ... air hinders the formation of clouds, so very little rain falls on the land ... In fact, the Atacama Desert is the driest place on Earth. ... With little vegetation to block it, the wind can carry sand and dust
Explanation:
i hope this help
Answer:
he was trying to say the answer was :
C.The open, flat areas of a desert prevent clouds from forming.
Which earthquake wave travels the fastest and arrives first?
a) S-wave
b) tension wave
c) P-wave
d) shear wave
Answer:
C) P-wave
Explanation:
P waves travel the fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave.
:Copper is a mineral commonly used in electronics. Copper ore deposits were created by volcanic activity. Heat and pressure creates copper ore and deposited it in sedimentary rock layers. Copper is considered a resource. renewable non renewable or conserved
No Links IF You Dont know the answer don't answer it
Answer:
Copper is a metal that has been deposited from hot sulphur solutions, created in volcanic regions. The hot solutions concentrated the copper up to a thousand times more than would normally be found in rocks. The resultant enriched rocks are called copper ores.
