Answer:
Option B
Explanation:
Nitrogen fertilizer runoff into the farmlands results into Eutrophication which is a form of nutrient enrichment of the water body. Because of the nutrient enrichment, the productivity of the water increases and hence the oxygen level of the water reduces thereby degrading the quality of water and adversely affecting the aquatic life in the water body

Answer:
the process of turning from liquid into vapour
Answer:
Evaporation is a surface phenomenon, which implies that the process only occurs at the surface of the liquid. During evaporation, the molecules of the liquid that are present at its surface overcome the intermolecular forces of attraction to break away from the liquid and escape into the atmosphere as a gas (or vapour).
Or

A tornado strips out a section of a forest. What type of succession is this? Why?
Answer:
Secondary succession
Explanation:
A secondary succession is when a type of disturbance happens when there is already soil present. In this case, it has already started out with a forest (including plants, trees, and wildlife). Other examples of a secondary succession include a wildfire, hurricane, flood, or human destruction.
This is different from a primary succession. A primary succession occurs when there is no soil present.

The diagram below represents some changes that took place in a bacterial population recently exposed to an antibiotic.Which statement would best explain the presence of bacteria on day 4?A) A bacterial population cannot survive exposure to antibiotics.B) This bacterial population cannot survive exposure to this antibiotic.C) Bacteria can change whenever it is necessary to survive antibiotic treatment.D) Some of the bacterial population was resistant to this antibiotic.
About the question:
You will find the diagram used to answer the question in the attached files.
Answer:
D) Some of the bacterial population was resistant to this antibiotic.
Explanation:
The term resistance refers to an inheritable change in a population sensitivity, reflected through the consecutive failure of the chemical effects, correctly used to reach a desired effect on the target population.
The excessive use of antibiotics on the bacteria population leads to the fixation of new mutated genes -by natural selection-. The mutated genes make these cells even more resistant to the drug.
In the exposed example we have,
Day 1 ⇒ a big population of white bacteria and only one black cell, probably carrying mutated genetic material.The population was treated with antibiotics.
Day 2 ⇒ there are fewer white bacteria and three black cells. This means that white bacteria are dying, while the black ones are reproducing.The mutated phenotype gets to survive under the effects of the chemical.
Day 3 ⇒ There are no more white bacteria. Only the black population survived and keeps reproducing.The mutated bacteria reproduce with the capability of tolerating the antibiotic dose that is usually used to destroy a population of white bacteria.
Day 4 ⇒ Black bacteria got to survive a produce a big population. Remember that bacteria follow the exponential growth model, meaning that their reproductive rate is too high. This black population survived the antibiotic action and reproduced at high rates.hello please help i’ll give brainliest
Answer:
abiotic
Explanation:
abiotic - nonliving components of an ecosystem that can affect the living organisms.
Temperature is a nonliving component and it affects the organisms that live within a certain environment.
Therefore the answer is Abiotic
Reasons its not the other answers:
Biotic factors must be living things
Temperature is not a living thing therefore Biotic cannot be the answer
Same with living, temperature is not living therefore the answer cannot be living.
Temperature plays a huge role in an ecosystem therefore it is considered an important component and the answer cannot be unimportant.

Are RNAs processed before translation is able to occur in Prokaryotes? Do only mRNAs undergo processing and maturation in Eukaryotes?
Answer: RNAs are not processed before translation in prokaryotes, this process only takes place in eukaryotes.
Explanation:
Messenger RNA or mRNA is a single-straded ribonucleic acid that transfers the genetic information from the DNA (deoxyribonucleic acid) molecule of the cell nucleus to a ribosome (which are the machinery responsible for protein synthesis) in the cytoplasm. mRNA determines the order in which the amino acids of a protein will be joined and acts as a template or pattern for the synthesis of that protein. To accomplish this, the DNA molecule must be transcribed into an RNA molecule, which is used for protein synthesis.
The messenger RNA obtained after transcription is known as primary transcribed RNA or precursor RNA or pre-mRNA, which in most cases is not released from the transcription complex in a fully active form, but in eukaryotes it must undergo modifications before it can perform its function (RNA processing or maturation). These modifications include:
Elimination of fragments (splicing): In most cases, the mRNA undergoes the removal of internal, non-coding sequences called introns, and the connection of exons. This does not occur in prokaryotic cells, as they do not have introns in their DNA.Protection by CAP: Addition to the 5' end of the structure called "cap" or "capping", which is a modified guanine nucleotide, 7-methylguanosine triphosphate, via a 5'-5' triphosphate linkage, instead of the usual 3',5'-phosphodiester linkage. This cap is necessary for the normal RNA translation process and to maintain its stability. Polyadenylation signal: Addition to the 3' end of a poly-A tail, a long polyadenylate sequence, whose bases are all adenine. Its addition is mediated by a sequence or polyadenylation signal (AAAAAA), located 11-30 nucleotides upstream of the original 3' end. This tail protects the mRNA from degradation, and increases its half-life in the cytosol, so that more protein can be synthesized.The mature mRNA (in eukaryotes) is transferred to the cytosol of the cell through pores in the nuclear envelope. Once in the cytoplasm, ribosomes are coupled to the mRNA. However, in prokaryotes, ribosome binding occurs while the mRNA strand is being synthesized. After a certain amount of time, the mRNA is degraded into its component nucleotides by ribonucleases. So, the transcription and translation processes are carried out in a similar way as in eukaryotic cells but they occur simultaneously. But, the fundamental difference is that, in prokaryotes, the messenger RNA does not undergo a maturation process and, therefore, no cap or tail is added and no introns are removed. Moreover, it does not have to leave the nucleus as in eukaryotes, because in prokaryotic cells there is no defined nucleus.
So, RNAs are not processed before translation in prokaryotes, this process only takes place in eukaryotes.

Explanation:
Choose the items that complete the sentence about the key features of f(x) = 8x. The y-intercept is Choose... , the asymptote is y = Choose... , and the range is y > Choose... .
Answer:
I suppose that the equation is:
f(x) = 8/x
(You wrote 8x, this is a linear function, so it has no asymptotes, then I assume that the actual function was 8/x)
The y-intercept is the value such that f(x) = 0
Notice that there is no value of x such that 8/x = 0 (if the numerator is never zero, then the quotient can't be zero)
So we do not have an y-intercept.
The asymptote:
Here we have four:
if x tends to zero from the negative side, then:
8/x tends to negative infinity.
if x tends to zero from the positive side, then:
8/x tends to positive infinity.
These two asymptotes can be written as:
[tex]\lim_{n \to \_-0} \frac{8}{x} = -\infty\\ \lim_{n \to \_+0} \frac{8}{x} = +\infty[/tex]
We also have two when x tends to plus infinity (and 8/x goes to zero) and when x tends to negative infinity, such that the function tends to zero again, these two can be written as:
[tex]\lim_{n \to \infty} \frac{8}{x} = 0\\ \lim_{n \to -\infty} \frac{8}{x} = 0[/tex]
Finally, the range:
The only value that y never reaches (only on limits) is:
y = 0
Then the range is the set of all real numbers except the zero, or:
R : { x ∈ R / {0} }

The diploid cells of a polar bear contain 74 chromosomes.
How many chromosomes are there
The genetic material that is passed from a parent to a child is called a chromosome. With a diploidy of 74 chromosomes, the haploid cell of the polar bear will have 37.
What is the difference between haploid and diploid cells?The number or ploidy of chromosomes in the somatic or germinal cells determines whether a cell is diploid or haploid. A twofold set of chromosomes is referred to as diploidy and is symbolized by the number 2n.
Haploidy, which is denoted by the number n, refers to the single or partial set of chromosomes found in germinal or reproductive cells. They describe the gametes that participate in fertilization.
If a polar bear's diploid cells (2n) have 74 chromosomes, its haploid cells (n) will have the following chromosome makeup:
2n = 74
n = 37
