Answer:
No, bears are consumers
Explanation:
Both decomposers and consumers are heterotrophic organisms, i.e., they cannot produce their own food. There are four different classes of heterotrophic organisms: decomposers, herbivores, carnivores and omnivores. The decomposers are heterotrophic organisms that return nutrients to the soil from the organisms that break down. Moreover, bears are classified as omnivores (consumers) that need to kill to get their food. These animals obtain nutrients and energy from both plant and animal sources.
Answer:
Bears are consumers

Which two of the following correctly describe what a gene is?
A packet of genetic information that can be passed down from one generation to the next
A DNA molecule
The entire collection of genetic information in a given species
A section of DNA that provides instructions for building a specific protein
I'm not sure
Answer:
A section of DNA that provides instructions for building a specific protein and A packet of genetic information that can be passed down from one generation to the next
Explanation:
A DNA molecule is not a gene, it is a nucleotide. The entire collection of genetic information in a given species results isn't a gene although many genes comprise what is the genome. Given that those two answers are not what genes are, the other two options are correct.
In the test for protein, why would some tubes show a slight purple color while others show a dark purple color?
Answer:
protein:
1. What is the name of the reagent used to test for the presence of proteins? (1 point)
Biuret reagent
2. What color indicates the presence of protein in a solution when the reagent is added? (1 point)
When Biuret is added, it would turn blue when it is negative but if it is positive then it would turn to a purplish to a dark purple. Showing that there is protein.
3. Which substances tested were positive for protein? (2 points)
The ones that were tested positive were milk solution and 50% egg solution.
4. Describe in your own words what we should do if the test tube for di-water tested positive for protein. (2 points)
Since Di water is our negative control, we know that there would be no proteins but if it was tested positive. Then we should start the experiment all over again this time with new, clean equipment.
What describes G and why they face the watery inside and outside of the cell
Answer:
Because they are hydrophilic
Explanation:
The cell membrane is made up of a phospholipid bilayer. The phospholipid bilayer is made up of an arrangement of phosphate heads, which are (attracted to water) hydrophilic, and fatty acid tails, which are hydrophobic. (repelled by water).
Because they are attracted to water, the phosphate heads face the outside of the cell, where the water is
In North America, many top predators, such as wolves, have been driven nearly to extinction. What effect do you think this has on their main prey, deer? Write your answer below, and discuss with your classmates.
Extinction refers to the elimination of species or groups of organisms due to human-made causes or natural events.
In North America, animals or predators such as wolves have been extinct that can affect the food chain and their prey.
The wolves in North America grew in number to such an extent that government and wildlife agencies developed the rules and regulations to hunt down and kill the wolves, which led them to near extinction.
Wolves feed or attack the deer and are a type of parasitism relationship. In this relationship, wolves are benefitted and deer are harmed.
The extinction of wolves will be led to an increase in the deer population, as deers are the prey and will have no fear from the wolves.
Thus, the deer population will increase in number.

Explanation:
Chap wanted to see if planting seeds deeper into the soil had an effect on plant height. He took ten containers and planted radish seeds at varying depths. He used the same type of soil, kept the plants in the same location, and gave them each 20 milliliters (mL) of water each day. Then, he measured the height of the sprouts every day for two weeks. What are the independent (test) and dependent (outcome) variables in Chap's experiment?
Answer:
Independent variable: Planting depths of seeds
Dependent variable: plant height
Explanation:
Independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response. In this experiment involving the planting of radish seeds at varying depths, the DEPTH AT WHICH THE SEEDS ARE PLANTED is the independent variable.
Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the HEIGHT of the radish plants measured is the dependent variable.

Explanation:
Matthias Schleiden used a microscope to observe that the
parts of plants consist of cells. Theodor Schwann used a
microscope to observe that the parts of animals consist of
cells.
Which two statements did the work of Schleiden and Schwann add to the cell
theory?
A. All living things are made of one or more cells.
B. All cells come from other living cells.
C. Cells contain genetic material that consists of DNA.
D. The cell is the basic structural and functional unit of life.
Answer:
The work of Schleiden and Schwann provided to the Cell Theory the conclusions relating to that all living things are made of one or more cells and the cell is the basic structural and functional unit of life.
Explanation:
Matthias Schleiden was a German botanist who in 1937, while studying plant tissue under the microscope, observed that all plants are made up of cells.
In 1938, physiologist Theodor Schwann performed an experiment similar to Schleiden's, but using animal tissue, concluding that animals are made up of cells.
By bringing together the findings of both scientists, two important conclusions for Cell Theory were reached:
The cell is the structural and functional unit of all living beings. All living organisms are made up of one or more cells.Both conclusions are part of the cellular theory, as it is known today.
Regarding other options:
B. All cells come from other living cells was a conclusion provided by Rudolf Virchow.
C. Cells contain genetic material that consists of DNA is an argument that is not part of the cellular theory. In fact, the DNA would not be discovered until 1953.

1)What is a trophic level?
2) explain how energy travels through food web ? your response must include the following terms:
Decomposer,producer, primary, consumer , 10%.
3)why is energy reduced at successive trophic levels?
1. The trophic level is something's position in the food chain/food web.
2. Energy travels through out the food chain because all the animals eat each other and take each other's energy. The decomposers are eaten, the producers are eaten, but the primary consumers get all the energy.
3. The energy decreases because each animal decomposes the energy a little, before getting eaten. By the time the food reaches the top of the web, the energy is barely left.

How does evolution explain the similar legs in mammals and explain why the function differently?
Answer/Explanation:
These are examples of homologous structures. These are derived from common ancestors , however, they do not necessarily perform the same function. A good example is the vertebrate forelimbs like the ones shown here.
These limbs all have the same basic pattern of bones. They inherited this pattern from a common ancestor, but they now have different functions. This is an example of divergent evolution
Give an example of an adaptive radiation. Provide evidence to support the claim that the radiation originated with one or a few species, that it was rapid and the descendant groups occupy a wide array of ecological niches. Suggest a hypothesis to explain why the radiation occurred.
Answer:
An example of an adaptive radiation with evidence to support the claim that the radiation originated with one or a few species is discussed below in details.
Explanation:
The method of evolution of various classes in a given geographical area originating from a spot and spreading to other regions or habitat is described as adaptive radiation. For example, modifications in nozzles of finches on Galapagos island.
Adaptive radiation indicates the adaptation of an organism that allows it to favorably spread, or radiate, into other circumstances. Adaptive radiation commences to speciation and is only used to explain living organisms.

what fossil layer will corals be present in
Answer:
polyp
Coral polyps secrete a rock-like skeleton of calcium carbonate around them. Calcium carbonate is also the dominant consituent of the rock, limestone. Because modern corals live in large colonies, these skeletons can become quite large, sometimes forming reefs.the soft tissue decays which leaves a hard skeleton behind the skeleton also that was preserved as a fossil of ancient coral and the coral that exists today all belong to the order of Scleractinia (SCLER-ac-TIN-ee-a). in the past the fossils found today lead to the conclusion that their where other kinds of coral which are now extinct The order Rugosa was dominated by solitary corals in which each coral polyp had its own skeleton. Rugose means wrinkled or rough, and the outer surfaces of most rugose coral skeletons has a wrinkled appearance. Because some of the solitary rugose corals formed horn-shaped skeletons, they are called horn corals. Some Rugose corals also formed colonies and coral heads. The order Tabulata consisted entirely of groups of coral animals that lived in large colonies with a shared skeleton. These colonial corals grew in mounds, branching shapes, as chain-like shapes, and even in shapes resembling pipe organs.

D. 24 ATPs.
Cellular respiration uses one glucose molecule to produce a total of 38 ATPs (option B).
What is cellular respiration?Cellular respiration is the process by which cells obtain chemical energy by the consumption of oxygen and the release of carbon dioxide.
Cellular respiration occurs in three processes namely;
Glycolysis; this is the cellular degradation of the simple sugar glucose to yield pyruvic acid, and ATP as an energy source. Krebs cycle; this is a series of enzymatic reactions that occurs in all aerobic organisms; it involves the oxidative metabolism of acetyl units, and serves as the main source of cellular energy.Electron transport chain; this is a series of electron transfer that results in the synthesis of large amount of energy.In total, the overall process of cellular respiration results in the formation of 38ATPs.

Detailed information about the processes and tectonic plate interactions that are causing the volcanos to occur. Include an explanation of convection currents.
Answer:
Tectonic plates recurring over and over again cause a rupture in the Earth's crust. This agitates the magma in volcanoes, causing the volcano to erupt.
Explanation:
Answer:
These tectonic plates rest upon the convecting mantle, which causes them to move. The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of mountains.
