What roles do humans play in biomagnification?
Answer:
The food chain
Explanation:
Biomagnification affects humans the most because we are at the top of the food chain, thus the accumulated toxins and chemicals are in their largest concentration amongst us.
which laboratory tools are useful when looking at internal organs of an earthworm
Answer:
An earthworm's internal organs can be viewed through a dissecting microscope. This type of microscope allows enhanced observation of objects that are too large for a compound microscope. Because the magnification is low, this microscope cannot be used to examine cells.

Rebecca’s family uses their house’s heating system to stay warm in the winter. How do they know when their system is at equilibrium?
A. The house temperature balances the set temperature and the system shuts off.
B. The house temperature is changing and the system is rapidly changing from on to off then back again.
C. The house temperature is lower than the set temperature and heat is on.
D. The house temperature is higher than the set temperature and the cooling is on.
Thank you.
Answer: A
Explanation:
Answer:
A. The house temperature balances the set temperature and the system shuts off.
Explanation:
Equilibrium is a state in which the competing factors of a system are in balance. In the case of the heating system, the house temperature and set temperature would be the same and the system would turn off.

PLEASE HELP!!!!! Describe in detail the process of dna replication
Answer:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. The replication process relies on the fact that each strand of DNA can serve as a template for duplication. DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand. Once synthesis is complete, the RNA primers are replaced with DNA, and any gaps between newly synthesized DNA segments are sealed together with enzymes. Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

How is a renewable resource different from a nonrenewable one?
A. A renewable resource is more likely to run out.
B. A renewable resource can never be replenished.
C. A renewable resource has a higher demand
D. A renewable re purse is replenished faster than it is used
Answer:
Explanation:
d
A renewable resource is different from a nonrenewable one by the fact that a renewable resource is replenished faster than it is used. Thus, the correct option for this question is D.
What is a Renewable resource?A renewable resource may be defined as a type of resource that significantly continues to exist in nature despite being consumed or can replenish itself over a period of time even as they are utilized by the organisms.
Examples of renewable resources may include wind power, solar energy, geothermal energy, biomass, etc. These resources are available in nature in unlimited amounts as compared to non-renewable resources.
Therefore, a renewable resource is different from a nonrenewable one by the fact that a renewable resource is replenished faster than it is used. Thus, the correct option for this question is D.

Hello! I have to write an essay based on the Water Cycle and what it is/does. I will give Brainliest for the correct answer. I will also give 20 points to whoever writes the essay, and has the correct answer. Good luck.
Answer: The water cycle also known as the hydrolic cycle describes the always foward rotation above and below the surfaces of the earth. The mass of water on earths surface remains fairly consistant. However, the water splits up into diffrent groups, freshwater, saline water, ice, and atmospheric water. The water can travel between catorgories such as river to ocean or ocean to atmosphere through evaporation, condensation, precipatation, surface runoff and subsurface flow. When water go through these physical process it can change aswell such as being a liquid, solid,and gas. During evaporation it takes water from it surroundings and cools its enviromwnt,
the exchanges in heat fluctuate the climates tempature.
Deoxyribonucleic acid and ribonucleic acid (DNA and RNA, respectively) are very important
biomolecules necessary for life. In at least 7 sentences and in your own words, compare
and contrast DNA and RNA. Explain what you know about the components (parts) of DNA
and RNA and their importance. Be sure to include at least five of the following words:

• Nucleic acid
• Nucleotide
• Nitrogen base
• Gene
• Genetic code
• Phosphate
• Sugar
• Protein
• Double helix
• Backbone
Answer:
pa heart follow back follow me brainliest me please
Explanation:
Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. They are both linear polymers, consisting of sugars, phosphates and bases, but there are some key differences which separate the two1. These distinctions enable the two molecules to work together and fulfil their essential roles. Here, we look at 5 key differences between DNA and RNA. Before we delve into the differences, we take a look at these two nucleic acids side-by-side.

What is the critical mass of a species?
A:The weight of all representatives of a species.
B:The weight of the last representative of a species.
C:The number of individuals that must exist for a species to continue.
Answer:
The number of individuals that must exist for a species to continue
Explanation:
I just had it on a quiz. Can I have brainliest?
The critical mass of a species is the number of individuals that must exist for a species to continue. Therefore, the correct option is C.
What is the critical mass of a species?The critical mass of a species refers to the minimum number of individuals that are required for a population to maintain its viability and continue to survive and reproduce in a given environment. This is also known as the minimum viable population (MVP) size.
The concept of critical mass is important in conservation biology because small populations are often more vulnerable to extinction due to genetic factors, environmental fluctuations, and other factors.
Therefore, understanding the critical mass of a species is significant for determining appropriate conservation strategies and protecting endangered species. Therefore, the correct option is C.

In cats, the bones in the legs involved in
walking are very similar to the bones of
whales' flippers that are involved in
swimming. These are examples of -
F: analogous structures
G: homologous structures
H: vestigial structures
J: endosymbiosis
Answers: G
Answer:
Your answer is most likely G), so you are correct.
These are the example of Homologous structure. So, the correct option is (G).
What are different types of structures?Homologous structures are similar in structure and location, but perform different functions, resulting in divergent evolution. For example, An arm of a human, the leg of a dog or a flipper of a whale are all homologous structures.
Analogous structures are similar in function but have different origins and structures resulting in convergent evolution. For example, from wings in birds, bats and insects to fins in penguins and fishes are all analogous structures.
Structures with similar anatomy, morphology, embryology, and genetics, but dissimilar functions are known as homologous structures, while structures that are superficially similar but perform the same physiological function are referred to as analogous structures.
Thus. these are the example of Homologous structure. So, the correct option is (G).
