Many cells make and use an enzyme, called catalase, to facilitate the decomposition of hydrogen peroxide (H2O2). The products of the decomposition are hydrogen (H2) and oxygen (O2). What is the effect of catalase on the decomposition of hydrogen peroxide? A. It decreases the activation energy needed to start the reaction. B. It decreases the total energy released by the reaction. C. It increases the total energy absorbed by the reaction. D. It changes the ratio of the amounts of the two products.
Answer:
A. It decreases the activation energy needed to start the reaction
Explanation:
Organic catalyst which speed up the rate of organic chemical reaction is living cells are called enzymes.They have specific reaction site called active sites.This must be in prefect shape with the substrate for the organic chemical reaction to take place
When this occurs the minimum amount of energy of reaction to activate or stimulate the the atoms and molecules of the substrate to undergo chemical reaction is lowered.This energy of reaction is celled activation energy.
Catalase thought its active sites lowers the activation energy so that the molecules of H2O2 could break down to C02 and H2 faster,thereby reducing the time for theses product to form.The is the general roles of enzyme.To increase the rate of chemical reaction,by reducing the activation energy.

Can be specialized for specific tasks in multicellular organisms Contain DNA Contain nuclei Are surrounded by a cell membrane Were the first photosynthetic organisms on Earth Can be specialized for specific tasks in multicellular organisms
Answer:
See the answer below
Explanation:
Prokaryotic cell: contain DNA, are surrounded by a cell membrane, were the first photosynthetic organisms on earth.
Eukaryotic cells: can be specialized for specific tasks in multicellular organisms, contain DNA, contain Nuclei, are surrounded by a cell membrane.
Prokaryotic cells are the earliest cells to be formed in the pre-oxygen earth. The photosynthetic prokaryotic cells released oxygen into the atmosphere during the process of photosynthesis and as such, other forms of cells were able to evolve. Prokaryotic cells lack a nucleus and membrane-bound organelles. Their DNA lies freely within the cytoplasm but the cell itself is surrounded by a cell membrane that controls the movement of substances in and out of the cell.
The eukaryotic cells evolved much later after the prokaryotic cell. It has both nucleus and membrane-bound organelles. The DNA is located in the nucleus and the cell is also surrounded by the cell membrane. The eukaryotic cells can aggregate together to form tissues, organs, or systems for a specific task in multicellular organisms.
Answer:
Prokaryotes.
1. Have dna.
2. Were the first photosynthetic organisms on Earth
Eukaryotes.
1. Have DNA
2. Have nuclei.
3. Are surrounded by cell membrane.
4. Can be specialized for specific tasks in multicellular organisms.
Explanation:
Prokaryotes are majorly unicellular organisms that have no membrane bound nucleus or organelles. They are the first photosynthetic organisms on Earth. They lack mitochondria and endoplasmic recticulum.
Eukaryotes are multicellular organisms that have membrane bound nucleus or organelles. They lack chloroplast and they gave mitochondria and Endoplasmic recticulum.

Is human survival independent of other species?
Explanation:
As far as I can think of, we're dependent on other species. If we can't be carnivores, then literally, the only other option I can think of is being a herbivore, and that still an organism. We need sufficient life essence to keep living. We CANNOT live without harming another organism.
In short of my babbling, human survival is not independent of other species.

True or False: In Biology, Fitness refers to how fast and strong an individual is. Explain.
Answer:
False
Explanation:
The biological fitness of a person's organism is dependent on their ability to survive and reproduce in a given environment. If different traits or alleles increase the fitness of an organism, those alleles will consequently increase in the gene pool, and that trait will increase in the population. This is how natural selection affects a population.

Three red square pieces of wood, four yellow square pieces, and five blue square pieces are put into a cloth bag. Four red round pieces, two yellow round pieces, and three blue round pieces are also put into the bag. All the pieces are then mixed about. Suppose someone reaches into the bag (without looking and without feeling for a particular shape piece) and pulls out one piece.
The question is incomplete. Here is the complete question.
Three red square pieces of wood, four yellow square pieces, and five boue square pieces are put into a cloth bag. four re round pieces, two yellow round pieces, and three blue round pieces are also put into the bag. All the pieces are then mixed about. Suppose someone reaches into the bag (without looking and without feeling for a particular shape piece) and pulls out one piece.
What are the chances that the piece is red round or blue round piece?
a. Cannot be determined
b. 1 chance out of 3
c. 1 chance out of 21
d. 15 chances out of 21
e. 1 chance out of 2
Because:
a. 1 of the 2 shapes is round
b. 15 of the 21 pieces are red or blue
c. There is no way to tell which piece will be picked
d. Only 1 of the 21 pieces is picked out of the bag
e. 1 of every 3 pieces is a red or blue round pieces
Answer: b. 1 chance out of 3
e. 1 of every 3 pieces is a red or a blue round pieces
Explanation: Inside the bag, there will be:
Total of squares: 3 + 4 + 5 = 12Total of round: 4 + 2 + 3 = 9Total of pieces inside the bag: 12 + 9 = 21The question is asking for a round red piece. The probability of that happening is
P(r) = [tex]\frac{4}{21}[/tex]
And a blue round piece:
P(b) = [tex]\frac{3}{21}[/tex]
It is a "OR" probability, so:
P(r or b) = [tex]\frac{4}{21} +\frac{3}{21}[/tex]
P(r or b) = [tex]\frac{7}{21}[/tex] or [tex]\frac{1}{3}[/tex]
Which means 1 out 3 pieces taken out of the bag will be red or blue.

You will write a creative story describing what happens to a goldfish in three distinct parts. Part 1: As it
passes your lips to the cardiac sphincter. Part 2: As it passes through the cardiac sphincter until it
reaches the place where the duodenum becomes the jejunum. Part 3: From the jejunum until it exits the
body. In doing this you will be responsible for identifying the anatomy involved as well as what happens
in the digestive process at each location.
Answer:
Major organs involved in the digestive system include the mouth, stomach, small intestine, large ... When it reaches your stomach, a sphincter opens and dumps the food in. ... To move into the small intestine, chyme must pass through the pyloric sphincter. From here it enters the duodenum, the first part of the small intestine.

In an experiment, 1000 rodents were released into a light brown sandy area where no rodents previously existed. The rodents' fur color was either brown, black, or tan. There was a known predator of the rodents in the same area. After several generations, what fur color frequency would a researcher expect to see?
Answer:
It is expected that rodents with brown color have more chances to increase their frequency in the population
Explanation:
The cryptic coloration (or camouflage), is an adaptation that organisms have developed to disguise their appearance, thereby blending in with the surrounding environment. The cryptic coloration is used by organisms as a strategy to hide their identity, movement, and location from their predators. In this case, it is expected that organisms with the same color of the surrounding environment would be the best to be selected by natural selection, i.e., these organisms would have more chances to survive and to reproduce.

What are ice cores and how are they useful in giving us info about the past?
Answer:
Ice cores are cylinders of ice drilled from ice sheets/glaciers. ice cores tell scientists about temperature, volcanic activity, atmospheric composition, precipitation, and wind patterns.
Explanation:
the thickness of each layer in the core allow scientists to determine how much snow fell in the area during a particular year. the layers are formed by layers of different types of snow. During the summer, when it is light for 24 hours, the snow on the top layer changes texture. When winter arrives, it turns dark and cold again and more snow falls on top of the summer snow, creating distinct layers.

Write a scientific explanation detailing the transfer of energy through an ecosystem. Using the energy pyramid below, determine how much energy will be transferred to each level of the pyramid if the producers have 1 million kilocalories, and explain where the rest of the energy will go.
Answer:
I cannot do math but i can tell you that less than 1 percentage of eneegy is transfered from the primary plant down the pyramid
The amount of energy that will be transferred to each level of the pyramid if the producers have 1 million kilocalories is as follows:
Producers = 1000000 kcal.Primary consumers = 100000 kcal.Secondary consumers = 10000 kcal.Tertiary consumers = 1000 kcal. What is an ecosystem?An ecosystem may be defined as a place or an area where individuals of different species live together and interact with one another for the purpose of food, shelter, and space.
According to the 10% law given by Lindemann, only 10% of energy gets transferred from one trophic level to the next while the remaining energy is utilized for various life processes of the organisms and some are lost as heat.
The left 90% of the energy is utilized in order to live, grow, reproduce, etc. While some energy may also be lost as heat in the environment.
Therefore, the amount of energy that will be transferred to each level of the pyramid if the producers have 1 million kilocalories is well described above.
