Answer:
To clean groundwater you must:
Explanation:
Eliminate the pollution source: An underground tank must be pumped dry and then dug out from the ground. A factory must be required to stop releasing toxic chemicals. Farms must be more careful about the chemicals they put on their fields.
Monitor the extent of the pollutant: Scientists test water in wells. Sometimes they drill wells to test water. They learn how the groundwater is flowing: how fast and in what direction. They study the contaminants in the groundwater. Then they determine where the contaminant plume is going.

Alleles are:
A)different genes
B)building blocks of DNA
C)proteins
D)alternate forms of a gene
Answer:
Alternate form of gene
Explanation:
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.

.Specific processes must take place within the cell for protein synthesis to occur. The processes that take place within a cell for protein synthesis to occur. Which occurs during translation but not during transcription? A DNA template is used to create an mRNA strand. A tRNA template is used to create a DNA strand. A tRNA template is used to create an mRNA strand. An mRNA template is used to create an amino acid chain.
Answer:
An mRNA template is used to create an amino acid chain.
Explanation:
Transcription is the first step in the protein synthesis process. Translation is the second.
Overall, the central dogma of biology is DNA->RNA->protein.
Transcription is that first step, DNA to RNA, and translation is RNA to protein: think of it like nucleic acids can just be transcribed, but nucleic acid to protein is like a whole different language, so it has to be translated. So the correct answer here is that mRNA is used to make amino acid chain (aka protein), which happens only in translation.
The picture shows a contractile vacuole of a unicellular freshwater organism. The contractile vacuole regulates the flow of water into and out of the cell in an aquatic environement. What condtions cause the contracile vacuole to fill with water? Your answer: A.The concentration of water is greater outside the cell than inside the cell. B.The concentration of water inside the cell is the same as the concentration outside the cell. C.The temperature of water in the vacuole is higher than the temperature of its environment.
Answer:
A. The concentration of water is greater outside the cell than inside the cell.
Explanation:
This is a question having to do with tonicity, or the concentrations of solutes or solvents across a membrane. In these conditions, there is a hypotonic solution inside the cell (hypo means low, because there's less water inside), which will cause water to come inside.
The contractile vacuole stops the cell from exploding by regulating the amount of water that can come in. Otherwise, it would lyse, or split open.
Ecosystems are closed environments.

When the two parental genotypes BB and bb are crossed, the genotype of all [tex]F_1[/tex] plants is Bb.
What is Genotype?An organism's genotype is defined as the complete set of genetic material that can also be used to refer to alleles or variants that occur in a particular gene or genetic locus.
The term "genotype" describes the genetic makeup of an organism as it describes the complete set of genes of an organism. This term can be used to refer to alleles, or variants of genes, carried by an organism.
When two organisms like BB parent crossed with bb parent, the offsprings that will produce is Bb.

enzymes are macromolecular biological catalysts. enzymes accelerate chemical reactions. almost all metabolic processes in the cell need enzymes in order to occur at rates fast enough to sustain life. without them life on earth would probably not exist. identify two factors that can affect the structure and function of an enzyme and describe what causes the change to occur. course hero.
Answer:
Enzyme is a catalyst
Explanation:
Enzymes make the chemical reaction faster than usual because the activation energy required for a substance to react becomes low with presence of enzymes. if we don't have enzymes it may result to slow metabolic processes. some environmental factor can affect enzymes like over exposed to radiation can activate the enzyme causing it to disrupt. or consuming a mutagenic agents that may affect the enzymes activities.

What is a herbivore?
A. an animal that gets energy from eating other animals
B. an organism that gets energy from eating only plants
C. an animal that gets energy by eating both plants and other animals
D. an animal that eats only herbs
An herbivore is an animal or organism that gets energy from eating only plants, which is present in option B. Examples are the goat, cow, etc., and they eat the producers, such as the plants.
What is the role of the herbivore?The herbivore is the animal that directly eats the plants of the ecosystem, which are later eaten up by the carnivore, and the herbivore gets more energy than the carnivore as they get energy directly from the plant source. The herbivore only eats plants, and the different ecosystems have different herbivores, such as the land ecosystem, which has the goat, elephant, cow, etc.
Hence, an herbivore is an animal or organism that gets energy from eating only plants, which is present in option B. Examples are the goat, cow, etc., and they eat the producers, such as the plants.

C. The molecule has no nitrogen atoms.
D. The molecule has an OH group on the end.
We know the molecule below is an unsaturated fat because the molecule contains carbon double bonds.
What is an unsaturated fat in molecule?An unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain. A fat molecule made of chains where some carbon atoms are not fully saturated with hydrogen atoms.
Unsaturated fat, a fatty acid in which the hydrocarbon molecules have two carbons that share double or triple bond and are therefore not completely saturated with hydrogen atoms. Due to the decreased saturation with hydrogen bonds, the structures are weaker and are, therefore, typically liquid at room temperature.
Unsaturated fats are either monosaturated fats, as in olive or canola oils, or polyunsaturated fats, as in nuts, seeds, and seed oils
The correct answer is option A.

Which option describes cations?
Answer:
D
Explanation:
A cation is a positively charge ion, such as a sodium ion, as when it becomes an ion, it gives away electrons, becoming positively charged.
The opposite is an anion, which is a negatively charged ion, such as oxygen as it receives elections from the cation when forming an ionic bond.
Cations are the positively charged ions.
What are cations?A cation has more protons than electrons, consequently giving it a net positive charge. For a cation to form, one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them.
The number of electrons lost, and so the charge of the ion, is indicated after the chemical symbol, e.g. silver (Ag) loses one electron to become Ag+, whilst zinc (Zn) loses two electrons to become Zn2+.
In contrast, most nonmetallic atoms have a stronger attraction to electrons than do metallic atoms, and as a result, they gain electrons to form anions.
Therefore, Cations are the positively charged ions.
