Answer:
The Gulf Stream is caused by a large system of circular currents and powerful winds, called an oceanic gyre.
As the warm water comes in, colder, denser water sinks and begins moving south—eventually flowing along the bottom of the ocean all the way to Antarctica.

A student drew the following diagram to model the structure of a prairie
community. Which level represents short and tall grasses?
A. Level 2
B. Level 1
C. Level 4
D. Level 3
Answer: B. Level 1
Explanation:
The prairie community is dominated by the grass and vegetation cover. Thus the lower most trophic level in the prairie ecosystem are the short and tall grasses. They produce major source of biomass for the herbivores of the food chain. They consume the grasses can be designated as primary consumers of the food chain. Also the producers which are grasses which make up the large amount of biomass will provide a source of food for the consumers. They will receive 100 percent energy from the sun and they will utilize 90 percent of it to make their food by the process of photosynthesis. Only ten percent of energy is transferred to the next trophic level.

however, crossover can cause endless possibilities of genotypes!
Suggest why energy from the sun flows in one direction while materials are cycle within an ecosystem
Answer:
Energy flow in an ecosystem is unidirectional. It means that energy which is absorbed by the producers from sun and is converted into chemical energy, always flow from a lower trophic level to a higher trophic level as in a food chain when herbivore consumes producers the energy is transferred from producers to consumers and so on. Some of this energy is assimilated some is used by the organism and some is dessipated in the environment but the flow of energy is never reverted, that is obviously a producer can not consume a consumer.

How does your model show what happened to the circled rock material as a result of plate motion?
Answer:
Once exposed, they are weathered, both physically (by mechanical breaking of the rock) and chemically (by weathering of the minerals), and the weathering products — mostly small rock and mineral fragments — are eroded, transported, and then deposited as sediments. Therefore, the model should show signs of deterioration and subduction.

why is earth's crust necessary for any life to take hold on our planet
Answer:
I think is this
Explanation:
The crust is a thin but important zone where dry, hot rock from the deep Earth reacts with the water and oxygen of the surface, making new kinds of minerals and rocks. It's also where plate-tectonic activity mixes and scrambles these new rocks and injects them with chemically active fluids.
If water is being extracted from an underground aquifer at a lower rate than precipitation is replenishing the aquifer, then the aquifer will eventually fill beyond
capacity.
True
False
Answer:
True
Explanation:
If precipitation occurs more frequently and it precipitates more than what is being extracted, it will eventually fill beyond capacity.
WILL MARK BRAINLIEST Identify 2 organisms that would have a decreased food supply if insects were removed from the food web,
Answer:
Frogs and voles would have less food supply.
Explanation:
There would be more food for the rabbits and slugs, so their populations would increase. However, ( there would be less food for the frogs and voles), so their populations would decrease. This means less food for the foxes and hawks. However, there are likely to be more rabbits and thrushes for them to eat, so their populations might stay the same.

A. Identify two examples of environmental factors that may impact myeloperoxidase activity. Describe how each of the environmental factors would affect the reaction tare of an enzyme.
B. Predict the how researchers can use myeloperoxidase activity as oxidative stress biomarkers in patients with rheumatoid arthritis. Provide reasoning to justify your prediction.
Answer:
So... MPO is most abundantly expressed in neutrophil granulocytes, and produces hypohalous acids to carry out their antimicrobial activity through oxidative damage during the respiratory burst. It requires heme as a cofactor.
Regarding environmental factors ... obviously the first factor is the presence of an infection and inflammation that cause an increase in the activity and production of MPO. Second, alterations in the MPO gene cause its congenital deficiency which predispose to infections.
Rheumatoid arthritis is an autoimmune and autoinflammatory rheumatoid disease in which significant joint damage is observed. In the joint capsule, inflamed infiltrates are observed composed of neutrophils and lymphocytes. Measurement of MPO levels in the joint cavity could therefore be related to the amount of neutrophils and thus to the extent of the inflammatory damage.
When the respiratory burst occurs, MPO is most abundantly expressed in neutrophil granulocytes, which then create hypohalous acids to carry out their antimicrobial function through oxidative damage.
What is MPO?Regarding environmental causes, the first one is undoubtedly the existence of an infection and inflammation, which elevate MPO activity and production.
Second, changes to the MPO gene result in its congenital deficit, which makes people more susceptible to infections.
Therefore, the amount of neutrophils and, consequently, the severity of the inflammatory response might be connected by the measurement of MPO levels in the joint cavity.
Therefore, When the respiratory burst occurs, MPO is most abundantly expressed in neutrophil granulocytes, which then create hypohalous acids to carry out their antimicrobial function through oxidative damage.

Which amino acids do the following codons encode - UUC,
UCU, CUU?
The amino acids which are encoded by the following codons are UUC- Phenylalanine, UCU- Serine, and CUU- leucine amino acid.
What are codons?
A codon is a DNA or RNA sequence which is made up of three nucleotides that forms a unit of the genomic information that encodes for a particular amino acid or signaling the termination of protein synthesis i.e., stop signals in a cell. There are about 64 different codons of which 61 specify amino acids and 3 are used as stop codons that terminate translation process. The 61 codons codes for 20 amino acids in the human beings.
The codons given in this case encodes for different amino acids which are UUC encodes for phenylalanine, UCU encodes for serine amino acid, and CUU encodes for leucine amino acid.

A. tRNA delivers DNA code to the ribosome and mRNA delivers amino acids to the ribosome
B. mRNA delivers DNA code to the ribosome and tRNA delivers amino acids to the ribosome
C. tRNA delivers DNA code to the nucleus and mRNA delivers proteins to the ribosome
D. mRNA delivers DNA code to the nucleus and tRNA delivers proteins to the ribosome
Answer:
The right answer is D.
Explanation:
The messenger ribonucleic acid, messenger RNA, or mRNA is a transient copy of a portion of the DNA corresponding to one or more genes. mRNA is used as an intermediate by cells for protein synthesis. Jacques Monod, François Jacob, and their collaborators issued and showed the concept of messenger RNA in 1960.

All of them grew from one progenitor species, which inhabitated the islands only a few million years ago.
This process, whereby species develop rapidly to use empty ecospace, is called as adaptive radiation.
