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
Answers
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.

d.
All of the above
Please select the best answer from the choices provided
A

Answers
Answer:
B - Water is filtered as it passes through the root systems of trees.
Explanation:
Water is filtered as it passes through the root systems of trees. So, the correct option is (B).
What are Trees?A tree is defined as a perennial plant with a tall stem, or trunk, usually supporting branches and leaves where the tree may be narrower consisting of woody plants with only secondary growth, such plants Those that are usable as timber or are plants above a specified height.
Trees are described as large and tall plants with very thick, woody and rigid stems called trunks. This single main stem or stem gives rise to many branches which bear leaves, flowers and fruits.
Trees improve water quality by a process called soil erosion which prevents sediment from entering storm drains and streams, filtered through the root system of trees
Thus, Water is filtered as it passes through the root systems of trees. So, the correct option is (B).

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:

protoporphyrin ix fluorescence and photobleaching during interstitial photodynamic therapy of malignant gliomas for early treatment prognosis
Answers
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).

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.

Fermentation does not produce ATP. Why is fermentation such an important process in cells
Answers
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,
What two characteristics are useful for supporting the photosynthetic mode of energy generation found in euglenids?.
Answers
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.

A cell with 30% solute is in an environment that consists of 25% solute. Which statement is true?
A.water will move both into and out of the cell equally.
B. Water will move into the cell.
C. Water will move out of the cell.
Answers
Answer:
Hypotonic solutions are those with less solute (again read as higher water potential). Isotonic solutions have equal (iso-) concentrations of substances. Water potentials are thus equal, although there will still be equal amounts of water movement in and out of the cell, the net flow is zero.
