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.

Is the animal cell unicellular or multicellular.
Answer:
Most of them are unseen, visible only under a microscope. These tiny organisms are unicellular, composed of only a single cell. The familiar plants, animals and fungi that we can see represent only a tiny fraction of life on Earth. These organisms, being made of more than one cell, are called multicellular.

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.

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.

A student is studying Earth's layers. She is trying to determine how temperature and density change from one layer to another. Which relationship that exists between Earth's layers did the student most likely find?
A. The temperature of Earth's layers decreases with depth, while density increases with depth.
B. The temperature of Earth's layers increases with depth, while density decreases with depth.
C. The temperature and density of Earth's layers decrease with depth.
D. The temperature and density of Earth's layers increase with depth.
Answer:
The answer is D!
As one gets closer to the Earth's core, temperature, and pressure rise gradually. Thus, option D is correct.
What are the factor involving in the earth layer study?Gravity will tug on something more strongly the denser it is. The consequence is that less dense layers migrate away from the Earth's core, while the densest components are attracted closer to it.
Because it is the densest and is formed of solid iron and nickel, the inner core is located near the center of the Earth.
The surface, where the water is the warmest, has the lowest density. The pycnocline is a zone of rapidly rising density with depth that is present as depth increases.
The density has an inverse relationship with volume and a direct relationship with mass. As a result, the density rises as the volume shrinks.
Therefore, The temperature and density of Earth's layers increase with depth.

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.

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.
