compare how is the overall chemical reaction for cellular respiration related to the overall chemical reaction for photosynthesis
Answer: cellular respiration reverses the overall photosynthetic reaction, but less efficiently. The useful energy output of respiration is less than the energy input required for photosynthesis.
Explanation:
overall photosynthetic reaction
Light energy + 6CO2 + 6H2O —> C6H12O6 + 6O2
cellular respiration
C6H12O6 + 6O2 —> 6CO2 + 6H2O + energy (as ATP and heat)
Whales, birds, snakes, and fish need oxygen to survive. Even though they share this trait, these animals are not related because they do NOT —
A. inherit genetic instructions passed down from the same parents.
B. lives in the same type of environment.
C. eat the same types of food.
D. need oxygen to survive in their environments.
Answer:
A. inherit genetic instructions passed down from the same parents.
These animals are not related because they do not inherit genetic instructions passed down from the same parents. The correct option is A.
What is inheritance?The transmission of traits and otherwise information through one generation of individuals or cells to the next is referred to as inheritance.
Inheritance can occur through one of two mechanisms: genetic inheritance or epigenetic inheritance.
Deoxyribonucleic acid is another name for DNA. It is the genetic structure that is in charge of storing information.
A nitrogen base, sugar, and phosphate backbone make up DNA. Inheritance occurs when genetic information is passed from a parent to a child, and thus from one generation to the next.
A gene pair's two alleles are inherited, one from each parent. Alleles interact with one another in various ways. These are referred to as inheritance patterns.
Thus, the correct option is A.

Erosion from glaciers takes a long time because glaciers move very slowly across the land. For example, The Appalachian Mountains in the U.S. used to be really tall but slowly overtime, glaciers rounded them off.
A student noticed that when a dog is cut, the dog periodically licks its wounds. Usually
after a few days, the wound begins to heal without ever showing
signs of infection. The
following steps outline the student's line of reasoning:
1. I wonder why the dog's wound doesn't become infected.
2. The dog's saliva must prevent the growth of infection-causing bacteria.
3. I'll obtain a bacterial culture and grow the same kind of bacteria in two identical
culture dishes. Once the bacteria start growing, I'll add dog saliva to only one of the
dishes and leave the other alone. I'll cover both dishes. Then I'll observe what
happens each day for a week.
4. Even after adding the dog saliva to one of the dishes, the bacteria continued to grow
in both dishes over the course of the week. However, the bacteria in the treated dish
grew more slowly than the bacteria in the untreated dish.
5. I think I'll try something else. I'll start with two identical culture dishes, as before, and
use the same kind of bacteria in each dish, but this time I'll treat one dish with dog
saliva before I add the bacteria. I'll observe what happens each day for a week. 12.

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.

Which biomolecule provides cells with the most energy per gram?
lipids
proteins
nucleic acids
carbohydrates
Answer:
carbohydrates
Explanation:
Among the choices above, it is "carbohydrates" that provide the most energy per gram. Although both carbohydrates and proteins provide 4 calories per gram, carbohydrates contain the most number of glucose, which is being used in order for the body to have energy. So, if you want a quick way to become energetic, it is best to eat "healthy carbohydrates" than proteins.
Around 60% of proteins are converted into glucose while 100% of carbohydrates are converted into glucose. Therefore, carbohydrates provides more energy.
Which activity causes the least amount of wetland and estuary degradation when it occurs near the coast?
A. dune grass rehabilitation
B. hydrologic alterations
C. agricultural development
D. urbanization and land development
Answer:
The activity which causes the least amount of wetland and estuary degradation when it occurs near the coast is:
A. dune grass rehabilitation
Explanation:
This is actually a rehabilitation effort, unlike the other three options that cause land degradation. A dune grass rehabilitation accretes sand and minimizes the rates of beach erosion. The program tries to protect coastal infrastructure and upland properties from storm damage by planting vegetation, fencing off sensitive areas, blocking storm surge, creating dune walkways, and absorbing wave energy. During dune grass rehabilitation, activities that adversely affect the dunes are avoided.
