The effects of biomagnification are most dramatic in the larger organisms in comparison to the smaller ones.
What is Biomagnification?Biomagnification can be defined as the accumulation of a particular substance such as chemicals in the body of living organisms at different trophic levels of a food chain. An example of biomagnification is the accumulation of insecticide DDT that gets accumulated in zooplanktons. Small fishes consume these zooplanktons and dies and this disturbs the aquatic food chain.
Biomagnification happens when toxic chemicals, whose remains in the environment are consumed indirectly by organisms through food. When an organism in the higher food chain consumes the organism at lower levels containing such chemicals, the chemicals get accumulated in the higher organisms.

How many trophic levels do most food webs have? Why? Relate your answer to the appropriate law of thermodynamics
Answer:
Most food webs have between 4 and 5 trophic levels
Explanation:
Energy flow: From the whole quantity of energy that reaches the earth's surface, autotroph organisms or producers only absorb 0.1 or 1%.
From the input of solar energy begins a unidirectional energy flow. It passes through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is eventually dissipated in the environment.
There is an energy transfer from each trophic level to the next, and each level only uses 10% of this energy. This assessment is called "The 10% rule". As a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time. The rest of the energy is used by the organisms in their own metabolism or dissipated as heat to the environment.
The progressive reduction of energy determines the number of trophic levels, which, in general, turns to be between 4 and 5.
Humans maintain a constant body temperature by using __
Answer:
The hypothalamus helps keep the body's internal functions in balance. It helps regulate: Appetite and weight. Body temperature
Explanation:
Answer:
Hypothalamus or the dermis
Explanation:
Our internal body temperature is regulated by a part of our brain called the hypothalamus. The hypothalamus checks our current temperature and compares it with the normal temperature of about 37°C. If our temperature is too low, the hypothalamus makes sure that the body generates and maintains heat.

Mitosis results in two diploid cells that have the same genetic makeup. Meiosis results in four haploid cells that are all genetically different from each other.
What is Mitosis?A kind of cell division known as mitosis occurs when a single cell (the mother) divides into two genetically identical daughter cells. Mitosis, when referring to the cell cycle, is the stage of cell division during which the DNA in the cell's nucleus is divided into two identical sets of chromosomes.
Mitosis is used in the vast majority of cell divisions that take place in your body. Mitosis fills an organism's body with cells during development and growth, and it replaces old, worn-out cells with new ones over the course of an organism's existence.
Mitotic divisions are a type of reproduction for single-celled eukaryotes like yeast, resulting in the generation of new members of the population.
Therefore, Mitosis results in two diploid cells that have the same genetic makeup. Meiosis results in four haploid cells that are all genetically different from each other.

You need energy to do any work, which is why the ability to do any work is energy. Read that again. Potential and kinetic energy are two forms of energy that can be converted into each other. Potential energy can be converted to kinetic energy and vice versa.
Explanation:
Humans produce the enzyme amylase. This enzyme breaks down starch, a
complex carbohydrate found in many food sources (e.g. potatoes, breads).
Explain why the human digestive system is unable to use amylase to break down
the complex carbohydrate cellulose, which is also found in some foods (such as
celery).
Explanation:
We lack the enzyme cellulase which is the enzyme required to break down cellulose.
Base on the given information, human can produce the enzyme amylase, but cannot produce the appropriate enzymes that is able to breakdown the beta acetal linkages that exist in cellulose.
Enzymes serves as biological protein, and it is needed in the body to carry out specific functions.
Human posses amylase which made it possible to breaks down starch that is contained in many carbohydrate food that we eat.
We can conclude that human doesn't have the enzymes that that act on complex cellulose contain in found like celery.

Oy=12
Oy=6
Oy=5
y=2
If x and y vary inversely and x=3 when y=8, then y will be 6 when x=4. Therefore, option (B) is correct.
What is the value of Y?If x and y vary inversely, it means that their product remains constant. Mathematically, we can write this as x * y = k, where k is a constant.
We are given that x = 3 when y = 8. Using the formula above, we can find the value of k:
x * y = k
3 * 8 = k
k = 24
Now we need to find y when x = 4. Again, using the formula above:
x * y = k
4 * y = 24
y = 6
Therefore, the option is Oy=6.

What is the activation energy. Ea for this reaction? Show your work?
Answer:
The activation energy depends on reactive species.
Explanation:
The minimum amount of energy required by the reacting species in order to start a specified reaction is called activation energy. Without activation energy, the reaction can be started so activation energy is very important for occurring of a chemical reaction. There are different amount of activation energy is needed to start different chemical reactions so we can conclude that activation energy depends on the type of reactive species and on the reaction.
An EMT reaches the scene of a car accident, disinfecting and dressing a man's head wound that has been bleeding profusely. Upon taking off his bloodied latex gloves, he notices that a shard of window glass has penetrated one glove and cut is palm. Years later, long retired after a second career as an accountant, he is surprised to discover that he has liver cancer. Thinking back, he recalls having received both hepatitis vaccines available at the time of the exposure, and guesses that he may most likely have been exposed to __________.
Answer: hepatitis C.
Explanation:
Based on the information given in the question, it's most likely that the person has been exposed to hepatitis C.
Hepatitis C is an infection that is caused when a virus attacks the liver which leads to the inflammation of the liver. Since the person reaches the scene of a car accident, it's possible that the EMT got in contact with the contaminated blood. In this case, he most likely have been exposed to hepatitis C.

Explanation:
Images that you see in your peripheral vision are not as sharp as those directly in front of you because: there is a higher concentration of cone cells in the center of the retina in an area called the fovea. there are fewer rod cells in areas of the retina where images from the periphery are focused. the lens cannot focus images well on areas of the retina where images from the periphery are projected. the rod cells in the periphery are sensitive to blue and green light only.
Answer:
The correct answer is ''there is a higher concentration of cone cells in the center of the retina in an area called the fovea.''
Explanation:
The fovea, the central area of the macula, is the area of the retina where the vision of details is the most accurate. It is located in the extension of the optic axis of the eye. The fovea is populated only with cones, and allows us the best optical resolution, the field of vision that occurs around the central focus / outside the center of the field of vision (fovea) is known as peripheral vision, it is related to the location and recognition of the visual information that is around the object on which we fix our attention. That is, it is one that uses the peripheral area of the retina and that gives rise to the field of vision that surrounds the point where the sight is fixed / allows us to see the environment that surrounds us in a general way.

Why is an imbalanced high population of moose on the island seen as a
problem? *
If the moose population continues to grow, they will run out of space on the island and
take over the wolf niche.
If the moose population is unchecked, the local balsam fir population will be
decimated, leaving a barren ecosystem.
It was not seen as a problem; science believes we should let the ecosystem run its
course and dies out.
It was not seen as a problem because the absence of wolves on the island ensured
the future of the ecosystem.
Answer:
If the moose population is unchecked, the local balsam fir population will be decimated, leaving a barren ecosystem.
Explanation:
The imbalanced high population of moose on the island seen as a problem because it decreases the local balsam fir population which is a major food source for the moose in the winter season. If the population of moose is grow higher then the scarcity of food sources occurs and the food source will be eliminated from that ecosystem. If the moose population increases the local balsam fir population will be eliminated from the ecosystem and the land will remain barren or without vegetation.
