Which organisms are most closely related?
Answer:umm a and b
Explanation:
Messenger RNA is the carrier of information from DNA to the ribosomes in the cytoplasm, where proteins are synthesized. The RNA
is transcribed from a DNA template. A special enzyme is involved in separating the two strands of the DNA molecule apart and
then hooks the RNA nucleotides together as they base pair along the DNA template. The special enzyme involved in this process is
called
A)
DNA primase
B)
DNA polymerase
RNA polymerase.
D)
helicase.
a promoter
Answer:
b.) DNA polymerase
Explanation:
Answer:

What is central dogma of life?The fundamental tenet of molecular biology explains how genetic information moves from DNA to RNA to produce a protein, a useful end product.According to the core dogma, RNA acts as a messenger to transport the information from DNA to the ribosomes, where it is used to produce all of our proteins.In the cell, the ribosomes work as factories where information is "translated" from a code into the usable component.Gene expression is the process by which the DNA instructions are translated into the functional result.Transcription and translation are the two essential phases of gene expression.Learn more about the central dogma of life with the help of the given link:

What two characteristics are useful for supporting the photosynthetic mode of energy generation found in euglenids?.
Answer:
An eyespot ( or photoreceptor) and a flagellum are useful for supporting the photosynthetic mode of energy generation found in euglenids
Explanation:
What use does the eyespot serve in euglena?
Near the reservoir, one can observe an eyespot on a euglena's anterior end. It can sense light. This supports euglena in locating sunny areas where they may capture sunlight for food preparation.
Euglena has two flagella one flagellum is very short and can not be seen clearly while the second one is large and can be observed. Flagella help euglena in locomotion or movement purposes and also in sensing environment. Flagella also help euglena in photosynthesis. While Euglena uses its flagellum to walk about in looking for food at night, Euglena contains chloroplasts and can do photosynthesis during the day.

Question 10 (3 points) Which statement about energy is true for all living things? Plants convert energy into ATP? Energy cannot transfer from one organism to the next? Energy comes only from sunlight? Organisms require energy for survival?
Fermentation does not produce ATP. Why is fermentation such an important process in cells
Answer:
In humans we go through Lactic Acid Fermination
Explanation:
It is important because after glycolysis we have the elctron carrier NAD+ reduced to NADH and we cant continue glycolysis until we have NADH back to NAD+ so all lactic acid fermintation does it removed the electron and allow glycolysis to continue. It should be noted that fermintation occurs when there is no oxygen / not enough to continue cellular respiration so we rely on glycolysis to produce very little ATP while oxygen is replenished,

Where do you find the x axis
Answer:
An x-axis is one of the axes of a two- or three-dimensional graph. The x-axis is the horizontal plane of a graph in a Cartesian coordinate system, which gives a numerical value to each point along the horizontal x-axis, as well as the vertical y-axis (in a two-dimensional graph).
Explanation:
X-axis is the line where the values of y-coordinate are zero for all the values of x. Then the data points for the x-axis are: (1,0), (-1.5, 0) Therefore the equation of the x-axis is y = 0, and its graph on the x and y graph chart is shown below.
Answer:
A coordinate grid has two perpendicular lines, or axes (pronounced AX-eez), labeled just like number lines. The horizontal axis is usually called the x-axis. The vertical axis is usually called the y-axis. The point where the x- and y-axis intersect is called the origin.

protoporphyrin ix fluorescence and photobleaching during interstitial photodynamic therapy of malignant gliomas for early treatment prognosis
Prior to therapy, a high PpIX fluorescence was observed in three patients; however, after iPDT, this fluorescence was entirely photobleached. These patients' viable tumor sections had high PpIX concentrations (mean PpIX uptake per tumor: 1.4-3.0 M).
Briefing:However, no or just minimal PpIX uptake (0-0.6 M) could be seen in the remaining two cases. Strong PpIX uptake patients demonstrated therapeutic response and long-term clinical stabilization (no progression at 29, 30, and 36 months); the remaining two patients experienced early treatment failure (death after 3 and 9 months).
Describe fluorescence:Two steps make up the chemical process of fluorescence first, a chemical fluorophore such a protein or carotenoid absorbs shorter-wavelength light (excitation), and then some of the absorbed energy is released as longer-wavelength light (emission).

What type of energy is present in lightning?
Electrical energy
Chemical energy
Nuclear energy
Potential energy
Answer:
electrical energy
Explanation:
As the charges that cause the energy are moving, electrical energy is a form of kinetic energy.
The type of energy present in lightning is electrical energy. When the electrical difference gets really big, it makes a way for electricity to flow out as lightning.
What type of energy is present in lightning?Lightning is one that is known to be a natural electric shock that happens during thunderstorms in the sky.
Therefore, This happens when electrical energy builds up and is released in the atmosphere. Lightning happens when there is an imbalance in electrical charge between the ground and the sky, usually because of positive and negative charges in a thunderstorm cloud.
Hence option A is correct.

effects on survival of bap1 and pbrm1 mutations in sporadic clear-cell renal-cell carcinoma: a retrospective analysis with independent validation.
A high-risk BAP1-mutant group and a favorable PBRM1-mutant group have been identified as mutation-defined subgroups of clear-cell renal cell carcinoma with differing clinical outcomes.
Why is the PBRM1-mutant group more advantageous and the BAP1-mutant group more risky?Different clinical behaviors are displayed by clear-cell renal-cell carcinomas. However, it is unknown what molecular genetic processes underlie these behaviors. We found that PBRM1 and BAP1 mutations are largely mutually exclusive and that BAP1 is mutated in roughly 15% of clear-cell renal-cell carcinomas.
145 patients from the University of Texas Southwestern Medical Center in the United States who had primary clear-cell renal cell carcinoma and known PBRM1 and BAP1 mutation status were evaluated between 1998 and 2011 for this retrospective investigation. We used The Cancer Genome Atlas (TCGA second )'s independent cohort (n = 327) for validation.
Those with BAP1-mutant tumors had considerably lower median overall survival in the UTSW cohort than patients with PBRM1-mutant tumors. Despite being rare (three in the UTSW cohort and four in the TCGA cohort), patients with mutations in both PBRM1 and BAP1 had the lowest overall survival.
These findings lay the groundwork for a molecular genetic classification of clear-cell renal cell carcinoma that may have an impact on future treatment choices.

What is the major difference between positive and negative feedback A positive feedback causes to continue of negative feedback cause it to stop or start B positive feedback results in temperature increases while negative feedback results in temperature decreases C positive feedback stimulates body system so while negative feedback shuts down body systems D positive feedback is controlled by external factors while negative feedback is controlled by internal factors
Answer:
A positive feedback causes to continue of negative feedback cause it to stop or start
Explanation:
A positive feedback occurs to help increase the output or increase the changes. While a negative feedback occurs to decrease or reduce the output or decrease the change. A positive feedback amplifies the results of any reaction to make the reaction more quickly and the negative feedback results in a reaction to reduce the system to its original state or stable state. Thus a positive feedback occurs to continue while negative feedback causes it to stop or to start.
