Answer:- Surface is primarily driven by wind (friction from wind transfers energy and momentum to surface water)
- Deep is slower, driven primarily by density (salinity and temperature) differences
- Thermocline: dramatic temp drop 50 m from surface bc sun can't shine
- Halocline: dramatic gradient in saline, increase as it deepens
- Pycnocline: resulting change in density (50-1000)
Explanation:
Which describes a eukaryotic cell, but not a prokaryotic cell?
A: is surrounded by a cell membrane
B: makes and uses proteins
C: contains DNA in a nucleus
Answer:
c?
Explanation:
eukaryotes have a nucleus and prokaryotes do not
Answer:
C.) Contains DNA in a nucleus
Explanation:
There are several differences between the two, but the biggest distinction between them is that eukaryotic cells have a distinct nucleus containing the cell's genetic material.

The graphs show the reaction rate for an enzyme across a range of temperatures and pH. Based on these data, this enzyme functions best at what temperature and pH? *
The graph is attacged and the options is as follows:
Temperature of 27oC and a pH of 4
Temperature of 37oC and a pH of 6
Temperature of 40oC and a pH of 8
Temperature of 50oC and a pH of 10
Answer:
The correct answer would be - temperature of 37oC and a pH of 6
Explanation:
The graph 1 shows the relation between the rate of reaction for an enzyme and the temperature of reaction is been represented. In this graph the rate of eaction is highest (point from the slope starts decreasing) at the So, by the options and graph the temperature 37°C(Below 40°C) rate of reaction is maximum.
Similarly, in other graph rate of reaction and and pH has been represented in which rate of reaction is maximum at pH 6. after 6 pH the rate of reaction started decreasing.
Often in laboratory experiments you will want to amplify regions of the genome from several different preparations of gDNA. To do this, a mastermix will be created with all the common reagents to ensure easier pipetting, proper mixing, and controlling for variations in pipetting. Create a mastermix for running 8 identical reactions, including one negative control, each with different gDNA templates (7 total gDNA templates).
Answer:
Mastermix in PCR helps in providing faster and easier setup with pipetting, proper mixing, reduction in contamination and controlling fir variation in pipeting or tube to tube variability. Contents of PCR master mix for the desired reaction are as follows:
dNTPsPrimersthermostable DNA polymerasecofactor (MgCl2)Template DNA (for 7 samples)PCR-grade waterThe only difference in negative control for the PCR master mix is template or the different primer rest the components are the same in the master mix.
Can you combine an apple and an orange to make a cross hybrid fruit? (Not sure this classify as biology)
Answer:
No
Explanation: Apples and Oranges are different species, therefore they are unable to interbreed. This would only be possible by gene splicing (Gene splicing is a form of genetic engineering where specific genes or gene sequences are inserted into the genome of a different organism) which is incredibly difficult.
Which of the following base pairs would be found in a cell
The base pair cytosine and guanine is found in the cell. The correct option is D.
What are base pairs?A base pair is a primary component of double-stranded nucleic acids that comprises two nucleobases that are hydrogen-bonded to one another.
They are the foundations of the DNA double helix and make a contribution to both DNA and RNA's folded structure.
Purines and pyrimidines are nitrogen bases that form hydrogen bonds between DNA strands.
Predicated by Chargaff's Rule, they associate together via complementary pairing A::T and G::C. The purines in DNA are the same as those in RNA: adenine and guanine.
The 2 significant pyrimidine bases in DNA are cytosine and thymine, which base pair with guanine and adenine. Uracil supplants thymine and base pairs to adenine in RNA.
Thus, the correct option is D.

A farmer has decided to dig an artesian well into the unconfined aquifer below his crops. However, water does not fill his well. Why isn't his well working?
A. An artesian well needs the pressure of a confined aquifer
B. An artesian well must be near a lake
C. An artesian well must be near the site of groundwater infiltration
D. An artesian well only works in areas that are going through a drought
Answer:
it is a
Explanation:
i did the test
A farmer has decided to dig an artesian well into the unconfined aquifer below his crops. His well is not working because an artesian well needs the pressure of a confined aquifer. The correct option is A.
What is an aquifer?An artesian well is a deep tube well drilled underground to gather water for human usage. This good type is found in restricted aquifers.
The artesian well differs from the others in that it does not require the use of a pump to raise the water, as the cistern does. The sort of subsurface reservoir causes the water that travels through the tube to naturally spurt to the surface.
The underground reservoir with the qualities required for drilling an artesian well is the product of extremely specialized geological conditions. Gushing wells are caused by the restricted aquifer, as this sort of deep groundwater is known. This type of reservoir is found between impermeable subsurface layers.
Therefore, the correct option is A. An artesian well needs the pressure of a confined aquifer.

After exposure, the scientist determines that some of the petri dishes have cancer cells.What factor do all the petri dishes that contain cancer cells have in common?
Answer:
they are normal mutations you can never have a cure to cancer you would have to throw a lot of your DNA and genes away to have a less chance of dying but we could slow or kill cancer but no way to prevent it from happning as it happens everyday to you but those cells have a higher chance to become cancer becuase of those thing that help cells to become cancer.
