Stacey wants to know if plants have the same phototrophic reaction from artificial light as they do from natural light. Using steps in the scientific method, design an experiment that will test this effect.
Explanation:
Yes I agree that plants have the same phototrophic reaction from artificial light as they do from natural light.
you have to take a big box an keep a small plant in it and make some holes in down side for taking carbon dioxide then attach a bulb in left side of the box and lit it and cover the box
after two days you will notice that plant is leaned towards the bulb
this show that plants have the same phototrophic reaction from artificial light as they do from natural light.
is this an underlined clause?

Answer:
Pancreatic juices may not reach the duodenum if the duct or papilla is blocked, or if the pancreas is so damaged by disease that it cannot produce adequate bicarbonate and enzymes. Lack of pancreatic juices results in inadequate digestion.
Hershey and Chase labelled phages with 32P and 35S. They found that the S35 labelled protein remained outside the cell and could be removed without affecting the phage infection. 32P labelled DNA entered the bacterial cells and could be found in progeny phages. Could this experiment have been performed using radioactively labelled hydrogen and carbon?
This experiment could not be performed using radioactively labelled hydrogen and carbon
The research of Hershey and Chase has shown that the genetic material they used to create the radioactive T2-bacteriophage is DNA (Viruses that infect E. coli bacteria). Virus T2 or the Enterobacteria phage The Group-I bacteriophage includes T2.
The T2-bacteriophage belongs to the Myoviridae family and has a linear, ds-DNA genome. The head, collar, and tail are the main components of the T2-bacteriophage's body. Because of its tail, the T2-bacteriophage resembles the T4-like virus or T4-bacteriophage.
In the Hershey and Chase Experiment, radioactive phosphorus (P32) and radioactive sulphur (S35) were used to identify the phage DNA and protein in order to determine which will infect E. coli. Hershey and Chase carried out a number of studies, including infection, mixing, and centrifugation, after labeling the phage DNA and protein.

Some people use paint to protect the outside of their houses. Why does a house painted a dark color get hotter than a house painted white?
Answer:
Dark color absorb more photons and thus gets more hot
Explanation:
Dark color is dark b/c it absorbs different wavelengths of light (think about little photons of light vibrating slighting differently) .This means it absorbs a lot of photons which makes it warmer.
If a thing is white, that means it reflects all lights and absorbs none. Thus, since it does not absorb photons (little packets of energy which is light), the house does not get warm.
Answer: Dark color absorb more photons and thus gets more hot

Two related populations separated by a mountain range for many generations eventually become different species providing an example of what type of speciation
Two related populations separated by a mountain range for many generations eventually become different species is an example of Allopatric type of speciation.
What is Allopatric speciation?Allopatric speciation is a type of speciation that occurs when a species separates into two separate groups which are isolated by a physical barrier from one another.
So we can conclude that two related populations separated by a mountain range for many generations eventually become different species is an example of Allopatric type of speciation.

Answer:
Chemical energy
Which form of energy does our food contain?
Yes, food serves as a basic source of the nutrients and energy needed to maintain and grow the body. Food contains what is referred to as "chemical energy" in terms of energy. This is nothing more than the bonds between the atoms that make up the specific food item, which the body may break down to release energy that it can use to create, repair, and ensure appropriate bodily function. This chemical energy is ultimately sunshine energy, which plants have the extraordinary capacity to use and store in the chemical compounds they produce, mostly in their leaves, using sunlight, water, and atmospheric carbon dioxide. Food does indeed contain energy, but that energy ultimately originates from the sun. Since people have known this for thousands of years, many civilizations revere the sun, along with water, air, and of course fire, as the source of life. For the body to function, energy is required by the muscles, brain, heart, and liver. The food we eat provides us with this energy. Our bodies break down the food we consume by combining it in the stomach with fluids (acids and enzymes). The carbohydrate (sugars and starches) in food is broken down into another form of sugar, termed glucose, during digestion in the stomach. The glucose is absorbed by the stomach and small intestines before being released into the circulation. Upon entering the bloodstream, glucose can either be utilized right away for energy or stored for later use. But in order to utilize or store glucose for energy, our systems need insulin. When insulin is absent, glucose remains in the circulation, which raises blood sugar levels. The glucose is burnt inside of your cells to create heat and adenosine triphosphate (ATP), a chemical that stores and releases energy as the cell requires. Either oxygen is present throughout the process of converting glucose into energy, or it is not. In the mitochondria, which are microscopic structures located in the gel-like fluid that fills every cell, glucose is transformed into energy using oxygen. This conversion results in waste products including water and carbon dioxide as well as energy (ATP, heat). Without oxygen, red blood cells convert glucose into energy because they lack mitochondria. ATP, heat, and lactic acid are produced as a result. Muscle cells also use glucose as a source of energy. Muscle cells are, well, double-jointed when it comes to converting glucose into energy. They can metabolize glucose with oxygen because they contain mitochondria. However, if the muscle cell's oxygen level plummets, the cells can simply convert glucose into energy on their own without it. When you have been working out so hard that you are physically out of breath, this is most likely to occur.

A boy with a mass of 40kg carries a load of 10kg up a stairs of 3m given(Force×Effort) calculate the force used to carry the box up the stairs.
a.30j
b.500j
c.1200j
d.1500j
tq for answering.
The force used to carry the box up the stairs is 500 N.
What is force?Force is an agent which causes a change in the motion or position or state of an object.
Force = mass * accelerationForce on the boy = 40 * 10 = 400 N
Force on the load = 10 * 10 = 100 N
Total force = 400 + 100 + 500 N
Therefore, the total or net force used to carry the box up the stairs is 500 N.

which of the following is an enzyme required by the process of rephosphory,to create ATP? A) AD Pase B)AT Pase C)Polymerase D)AT synthase ?
Answer:
D) ATP Synthase (Hopefully that was an option, I'm not sure if option D intentionally left out the P)
Explanation:
ATP synthase is responsible for synthesizing ATP through the phosphorylation of ADP. This is the result of mechanical energy being generated by the proton motive force (H+ ions moving into the matrix). The asymmetrical rod changes the affinity for ATP, ADP, and inorganic phosphates of each subunit in the F1 subunit, allowing ATP to be produced/prepped/released. In all, this enzyme is very important in the entire process of oxidative phosphorylation.
