Answer:
Dicer
RNA-dependent RNA polymerase amplifies siRNAs by binding to them and making more dsRNA, which is recognized and cleaved by Dicer into secondary siRNAs. The result is the silencing of genes by amplifying the RNAi effect. In certain cases RNAi also silences genes by the formation of heterochromatin.

After conducting the experiment and reviewing the data, a marine biologist states that sea
turtles nest from May to October and determines that August is the most critical month. This is
an example of which step in the Scientific Method?
A. analyze the results
B. conduct the experiment
C. form a conclusion
D. form a hypothesis
The scientific method includes the problem statement, previous knowledge, hypothesis and goals, methodology, results, and discusion/conclusion. The correct option is C. form a conclusion.
----------------
The scientific method is a research method that consists of systematic observations, measures, experimentation, analysis, and verification of a hypothesis. It is based on reproducibility and refutability.
When conducting an experiment, you need to consider,
Definition and problem statement. The question for which there is not an answer yet. A question the investigator wants to answer.
Theoretical framework. Antecedents from other investigations. Previous knowledge about the study object is always required for a better understanding.
The main goal of the study is basically what the investigator wants to find out.
Hypothesis formulation. The researcher makes a hypothesis to predict or make a conjecture -not verified and which requires corroboration- about what is going on or expected to happen.
Identification of the study groups, involved variables -independent, dependent, and control-.
Methodology description. Steps needed to get data.
Results. It includes data statistical analysis. This step involves testing the observations.
Discussion and Conclusion, through which the hypothesis might be rejected or accepted.
In the exposed example, the researcher has already collected field data, and made analysis.
Probably, the marine biologist noticed, while analyzing the results, that turtles lay eggs from May to October. But there might have been a biotic or abiotic factor threatening the survival of the eggs during august.
According to the analysis the researcher concluded that the nest season involves monthes between may and october, and august turns to be the most critical month for nesting.
The correct option is C.

HELP QUICKLY Why are the deepest high tides so deep and the shallowest low tides so shallow? Hint: how are the Earth, Sun, and Moon aligned?
There are different kinds of tides. This change occur because when the gravitational pull of the sun works along with the gravitational pull of the moon on Earth, it leads to the oceans bulging out.
This result above makes the high tides as been little higher and low tides been little lower than normal.Spring tides are known to be the deepest as oceans levels are highest in this kind of tide. The neap tides are known to be the shallowest.
This often occurs when the moon, earth, and sun are said to be at a right-angled plane. Therefore, the gravitation pull of the moon and sun on the oceans do counteract each other making its net effect is smaller.

condensation, precipitation, infiltration, runoff, and evapotranspiration are the correct steps of water cycle.
what is condensation ?It is the process by which water vapor is converted into liquid water. It is an integral part of the water cycle.
It shows how water continually converts into three forms solid, liquid, gas throughout the earth surface.
The boiling point and the condensation point are same and take place at 100 degrees Celsius.
The temperature range of condensation occurs between 0 degree Celsius to 100 degree Celsius.
In water cycle due to condensation water molecule forms a cumulous clouds and fog followed by fall down of water droplets on the Earth’s surface as precipitation, which is commonly called rain.
Rain water enters the earth’s waterways, soil absorbed by plants or freeze into its solid form ice form.

Draw the structure of ATP molecule and explain how it is formed
ATP is formed from the breakdown of glucose molecule in mitochondria of the cell.
ATP molecule is formed in the process of respiration i.e. aerobic and anaerobic. During aerobic cellular respiration, glucose reacts with oxygen in the mitochondria of the cell, forming ATP that can be used by the cell in different cellular activities. When glucose reacts with oxygen, three molecules are formed i.e. ATP, Carbon dioxide and water. ATP is used by the cell whereas the Water and carbon dioxide molecules are waste materials which are removed from the cell so we can say ATP is formed from the breakdown of glucose molecule in mitochondria of the cell.Learn more about ATP here: https://brainly.com/question/893601

Transcribe the following Strand of DNA:
GTCCTTTACCATCGATTGGAAAACGTTAAAATCCAGTTCCAT
Answer:
CCGATAGGT
Explanation:
got this for my hw.
Answer:
So the central dogma of molecular biology describes the journey from DNA to protein product:
DNA --transcription--> mRNA --translation--> Protein
Assuming the DNA sequence provided is the template strand (rather than the complimentary coding strand), we start by transcribing the sequence into mRNA starting on the 3' end of the DNA towards the 5' end (which would build the mRNA 5' to 3'). This process involves the enzyme "RNA polymerase," which can only add nucleotides to the 3' end of the mRNA, just like how DNA polymerase can only synthesize DNA in the 5' to 3' direction. The RNA polymerase will bind to the template DNA strand and synthesize the complimentary mRNA, substituting uracil for thymine (since RNA does not contain thymine like DNA).
In terms of transcribing the sequence given to you, we'll have to work backwards + flip it around to get the 5' to 3' mRNA since the DNA is given 5' to 3' rather than 3' to 5'. Due to the length and the fact that we'll have to use triplets in translation anyways, it can help to break the sequence into triplet codons now.
5’-AAG | TTA | ATG | AGA | AAT | CGA | CAT | GGG | GCG | CCG | AAA | GTA | TAA | CCG | TCT | TAG | AAT | AGC-3’
We can then cross out each codon as we transcribe it and flip the sequence to be 5'-3' mRNA:
mRNA: 5'- GCU | AUU | CUA | AGA | CGG | UUA | UAC | UUU | CGG | CGC | CCC | AUG | UCG | AUU | UCU | CAU | UAA | CUU -3'
Normally, mRNA sequences start with "AUG" which is the start codon (and codes for Methionine), but I'll assume this is just for practice translating + transcribing in general. There's also a stop codon before the end but I'll assume the same again.
Translation involves three main steps - initiation, elongation, and termination. Initiation involves the translation ribosome assembling around the mRNA starting at the 5' end start codon, and tRNA carrying an amino acid binding to the complimentary section of the mRNA. As each tRNA attaches and the ribosome moves along the mRNA, the amino acids on each tRNA are bonded into a longer and longer peptide chain and the now amino acid-less tRNA are ejected (elongation). Termination occurs when a stop codon is reached, the ribosome will end elongation and help fold the protein into its final structure.
To translate the mRNA sequence here we'll need an amino acid/mRNA codon chart. I don't believe I can attach an image here, but looking up those exact words should yield the right results in images.
5'- GCU | AUU | CUA | AGA | CGG | UUA | UAC | UUU | CGG | CGC | CCC | AUG | UCG | AUU | UCU | CAU | UAA | CUU -3'
Ala - Ile - Leu - Arg - Arg - Leu - Tyr - Phe - Arg - Arg - Pro - Met - Ser - Ile - Ser - His - STOP - Leu
Amino acids are often abbreviated into three letters (Ala = alanine, Met = methionine, etc), and sometimes are abbreviated as single letters, though I've only seen that for sequencing databases.
In terms of locations for each of these processes, transcription occurs in the nucleus for eukaryotes and translation in the ribosomes/cytoplasm.

Unmanned marine vehicles are useful because they help with marine tasks, completing them in less time, reducing risks, reaching deeper areas.
Unmanned marine vehicles (UMV) are robotic vehicles controlled from afar that allow us to explore the sea and perform tasks with minimum risks.
UMV is useful because:
They substitute people working at the sea in risky tasks,They allow deeper exploration of the sea.They do tasks in less time than humans.An example of how useful these marine vehicles are is during the construction of ports. They replace divers who have to do the job manually, spending many hours and risking their lives. With a UMV, there is no need for humans to go under the water, experts control the robot from the surface.
In conclusion, UMVs are useful because they are practical tools that save time and reduce risks.

In dogs, one pair of alleles determines coat color (dark and albino). Another pair of alleles determines hair length (short and long). Thus, each gamete will contain one of the coat-color alleles, C or c and one of the hair-length alleles, B or b. In repeated crosses of a specific dark, short-haired dog with an albino, long-haired dog, all the offspring were dark with short hair, as shown in cross I. However, in subsequent crosses of another dark, short-haired dog with a dark, long-haired dog, the ratios shown in cross II below were obtained. In cross II, the genotype of the dark, short-haired parent is which option choice.

Answer C: CCBB
Answer D: CCbb
Answer E: ccBB
Answer:
the answer is b
Explanation:
In cross II, the genotype of the dark, short-haired parent is which option choice. Answer A: CcBb
Genetic crossesIn genetic crosses, the allelic combinations that translate the phenotypes are called genotypes, and thus, the designations aa, Aa and AA represent the genotypes. In crosses of single-gene inheritance, in which there are dominance relationships, two different genotypes (Aa and AA) reproduce the same phenotypes. And when a cross occurs, both phenotypic and genotypic proportions can be observed.
With this information, we can conclude that the genotype in the second cross was heterogametic.
