What two body systems will work together to provide cells with energy?
A. Excretory and Digestive, because the nutrients from the digested food will be sent to the excretory to be delivered out as waste products.
B. Digestive and Muscular, because the nutrients from the digested food will be used immediately by the muscles for energy.
C. Respiratory and Excretory, because the oxygen will be transported to the cells so that wastes can be delivered out as a waste production.
D. Digestive and Cardiovascular, because the food will be broken down and nutrients will be sent in the bloodstream to the cells for use.
Answer:
Answer:
The correct answer for the first question would be B) the respiratory and circulatory systems.
Respiratory system is a set of organs which help in exchange of gases in the body. They bring oxygen from outside into the body and release carbon dioxide from inside the body to outside world. The exchange of the gases takes place at alveolar site (or gills in aquatic animals).
The circulatory system then carries this oxygen (mixed in blood) from gas exchange site to all the cells of the body. In addition, it also brings carbon dioxide (waste product of cellular respiration) from all the cells to the gas exchange site (respiratory system).
The correct answer of the second question would be C)the digestive and circulatory systems.
Digestive system helps in breaking down of macro-molecules (such as starch, polypeptide, fats) into smaller units (such as glucose, fructose, amino acids) as well as absorption of the same.
Nutrients from the absorptive site (usually small intestine) are then transported to the entire body with the help of blood through capillaries and arteries that is, circulatory system.
Explanation:
Body systems that will work together to provide cells with energy are:-Digestive and Cardiovascular, because the food will be broken down and nutrients will be sent in the bloodstream to the cells for use.
Digestive system will breakdown complex macromolecules into micro molecules which are then transferred into blood.Blood or Cardiovascular system will carry these micro nutrients to different parts of the body Describe digestive system?It is system that include organs that take in food and liquids and break them down into substances that the body can use for energy.
Describe cardio vascular systemThe circulatory system or cardiovascular system pumps blood from the heart to the lung to get oxygen. The heart then sends the oxygenated blood through arteries to the rest of the body. Veins carry deoxygenated blood from various parts of the body to lungs.To know more about body systems here

dy÷dx=(x-1)(x+3) at x=2
Answer:
[tex]\dfrac{dy}{dx}=\dfrac{4}{25}[/tex]
Explanation:
The given expression is :
[tex]y=\dfrac{(x-1)}{(x+3)}[/tex]
We need to find dy/dx at x = 2
[tex]\dfrac{dy}{dx}=\dfrac{d}{dx}(\dfrac{x-1}{x+3})\\\\=\dfrac{(x+3)\dfrac{d}{dx}(x-1)-(x-1)\dfrac{d}{dx}(x+3)}{(x+3)^2}\\\\=\dfrac{x+3-(x-1)}{(x+3)^2}\\\\=\dfrac{x+3-x+1}{(x+3)^2}\\\\\dfrac{dy}{dx}=\dfrac{4}{(x+3)^2}[/tex]
Put x = 2 in above expression
[tex]\dfrac{dy}{dx}|x=2=\dfrac{4}{(2+3)^2}\\\\=\dfrac{4}{25}[/tex]
Hence, the value at dy/dx is [tex]\dfrac{4}{25}[/tex]

someone may ask you to distill a complicated idea into a brief summary that gets right to the point. how does this relate to distillation in chemistry
Answer:To separate two or more liquids by distillation, you first heat them in a flask. The more volatile liquid (the liquid with the lower boiling point) will typically evaporate first and the vapor will pass into a ... the refluxing liquid can condense, re-evaporate, and condense again, essentially distilling the ...
Explanation:
Distilling a complicated idea into brief summary that gets right to the point relates with distillation in chemistry in that both requires breaking a complex idea/substance into smaller component pieces.
In chemistry, distillation is a technique used for separating a liquid mixture into its components by allowing each component to boil, evaporate off the mixture, and then allowed to condense.
Because the each component of a mixture has different boiling point, this attribute is applied in distillation. The mixture is placed in a distiller and heated. At their respective boiling temperature, each component evaporates off the mixture and condenses at a collection point by a cooling water.
This is what it means when a complicated idea is being asked to be distilled. Such idea is to be broken down into smaller, concise ideas that can easily be executed as part of the whole idea.

3.We anticipate our recombinant DHFR protein to be functional for use in future research applications. However, if you had been able to test functionality and found that your recombinant GST-DHFR-His protein was not functional, what would you propose is one potential issue you would investigate to troubleshoot further. In other words, what is one thing that could have gone wrong to result in non- functional protein from the method used and results obtained this semester
Answer:
In the given case, the protein would have required to go through the process of post-translational modification, however, the mentioned protein would have been cultured in the prokaryotic system, the process of post-translational modification would have failed to take place. This step would be essential for the functionality of the protein. Thus, there is a need to culture it within the eukaryotic system.
The covalent and generally the enzymatic modification of proteins post its biosynthesis is termed as post-translational modification.

Answer:
B. organism
Explanation:
Carolyn observed a freshwater plant, Elodea, in a small aquarium filled with freshwater on her desk. In one five-minute period, Carolyn counted 32 bubbles that formed on the plant’s leaves and were released into the water. She then moved the aquarium from her desk to a sunlit window and observed the Elodea again. In a second five-minute period, Carolyn observed 194 bubbles form and be released by the Elodea into the water.
a. Explain how the bubbles released by the Elodea signify that the plant is cycling matter. Provide evidence to support your answer.
Hello there! Photosynthesis
Objectives:
(Adaptable to grade levels 6-9)
The student will:
1. Observe evidence of photosynthesis in a water plant.
2. Assemble the equipment needed to measure the rate of photosynthesis in
elodea (water plant).
3. Count bubbles of oxygen gas given off by elodea to determine the rate of
photosynthesis.
4. Change the conditions of photosynthesis by altering light intensity and
carbon dioxide amount, and determine the effects on the photosynthesis rate.
5. Prepare a graph of the collected data and analyze it.
Materials Needed:
(For each group of four students)
elodea (water plant) lamp (40 watt)
test tube razor blade (single-edge)
dechlorinated water (room temperature) tape
sodium bicarbonate powder (baking soda) clock or timer
metal stand with rod or test tube rack metric ruler
Strategy:
PART A. Setting Up the Experiment
1. Obtain a sprig of elodea. Remove several leaves from around the cut end of
the stem. Slice off a portion of the stem at an angle and lightly crush the
cut end of the stem.
2. Place the plant into the test tube, stem end up, filled with water.
3. Secure the test tube to a metal stand with tape or place the test tube in a
test tube rack.
PART B. Running the Experiment
1. Place a 40 watt lamp 5 cm from the plant. After one minute, count and
record the number of oxygen bubbles rising from the cut end of the stem.
Count bubbles for five minutes. If bubbles fail to appear, cut off more of
the stem and recrush.
2. Run a second five-minute trial. Record and average your results.
3. Move the lamp so it is 20 cm from the plant. After one minute count and
record bubbles for two five-minutes trials. Again, average and record your
results.
4. Add a pinch of sodium bicarbonate powder to the test tube. Place the lamp
5 cm from the test tube. After one minute, record bubbles for two five-
minute trials. Average and record your results.
5. Prepare a graph of your results. Use the average number of bubbles for the
vertical axis. Use the type of environmental condition for the horizontal
axis.
Performance Assessment:
The students will answer these questions using specific values from the
investigation. Diagrams may be included.
1. How does this investigation demonstrate that plants give off oxygen during
photosynthesis? Explain your answer based on your observations.
2. How does the rate of photosynthesis change when the light source is moved
from a distance of 5 cm to 20 cm?
3. How does the rate of photosynthesis change when sodium bicarbonate is added
to the water?
Conclusions:
Plants use green pigments called chlorophylls to trap light energy. The
chlorophylls give a plant its green color. Inside the cells that have
chloroplasts, the light energy is used to make a simple sugar called glucose.
The process by which plants use light energy to make glucose is called
photosynthesis.
During this process of sugar production, carbon dioxide combines with water to
form glucose and oxygen is released. Oxygen that is produced in photosynthesis
is given off as a gas. If a lot of oxygen is being given off, photosynthesis is
occurring rapidly. If little oxygen is being given off, photosynthesis is
occurring slowly. The amount of trapped light energy and the amount of carbon
dioxide available affects the rate of photosynthesis.
The purpose of adding sodium bicarbonate powder to the water increases the
amount of carbon dioxide in the water.
This investigation can be performed with water plants grown in many parts of
the world, except regions that have permanent ice.
Return to Biology Index
The bubbles released by the Elodea signify that the plant is cycling matter because:
carbon is being fixedoxygen is being releasedCarbon in the form of carbon dioxide is being fixed in the Elodea through the process of photosynthesis according to the following equation:
[tex]6CO_2 + 6H_2O ---> C_6H_1_2O_6 + 6O_2[/tex]
During respiration by the same Elodea, the carbohydrate produced would be broken down in a reaction with oxygen to produce carbon dioxide and water:
[tex]C_6H_1_2O_6 + 6O_2 ---> 6CO_2 + 6H_2O[/tex]
Thus, important materials such as carbon and oxygen are being recycled in the photosynthetic process.
More on matter recycling can be found here: https://brainly.com/question/1192312
what are the inputs for photosynthesis and where are they used?
Answer:
In terms of inputs, outputs and energy transformations, photosynthesis can be summarized as follows. Inputs - Sunlight as energy source, carbon dioxide and water. Processes - Chlorophyll traps sunlight; the energy is used to split water molecules; hydrogen from water is combined with carbon dioxide to produce glucose.
