Which of the following pollutants are most likely the result of a living organism?
I. Mold
II. Pollen
III. Radon
Answer:
Mold and pollen are results of living organisms.
I and II only.
Although radon occurs naturally (radon gas is a result of uranium being broken down in the rocks and soil below our feet, stated in the lesson), the reason radon is not in this category is because it is not directly a result of living organisms, only of non-living elements of nature - soil and rock.
What’s the difference of anaerobic respiration and aerobic respiration
Answer:
Unlike aerobic respiration, anaerobic respiration does not need oxygen. It is the release of a relatively small amount of energy in cells by the breakdown of food substances in the absence of oxygen.
Have a good day <3
Explanation:
Aerobic respiration takes place in presence of oxygen; whereas anaerobic respiration takes place in absence of oxygen. Carbon dioxide and water are the end products of aerobic respiration, while alcohol is the end product of anaerobic respiration.

How did you revise your sequence from your initial idea ? Explain how you decided on the sequence . For the Natural Selection activity
Natural selection is the reason behind evolution.
What is natural selection?The term natural selection refers to the fact that organisms that possess certain favorable characteristics live long enough to reproduce and pass on these favorable characteristics to their offspring.
In the opinion of Charles Darwin, natural selection is the reason behind evolution and he explained this in his book titled ;"On the origin of species".

Answer:

Explanation:
Part A: Bb would be their genotype.
Part B: The offspring would be born with black hair if they were to have any of the dominant alleles. (BB or Bb) Their fur would be colored white if their genotype was "bb". The uppercase "B" represents the dominant allele and the "b" represents the recessive allele. Since there's "BB" and "bb" genotypes breeding, the only outcome for their offspring would be the "Bb" genotype.
A segment of DNA that codes for RNA, and can vary in length from a few hundred to as many as two million base pairs in length best defines a(n)
We can confirm that a segment of DNA that codes for RNA and can vary in length from a few hundred to as many as two million base pairs in length best defines a gene.
What is a gene?To expand on the definition given, we can say that a gene is, as mentioned, a series of base pairs known as nucleotides that will code for RNA. The RNA in question is messenger RNA that will later become a protein. Through this process, genes code for every aspect of an organism and will determine its morphology and all other biological aspects.
Therefore, we can confirm that a segment of DNA that codes for RNA and can vary in length from a few hundred to as many as two million base pairs in length best defines a gene.

The steepest slope on this hill can be found on the side that is facing which direction?
Answer: the answer is northeast
Explanation:
Answer:
Northeast
Explanation:
To find the steepest part of a topographic map, simply look at the contour lines and if they are close together, they are steep, but if they are distanced fairly they are at a gentler slope range. Also if they are very far apart the land would be flat, which is both good for farming and housing. Since there was no topograpic model of a land structure given in this answer, I chose to go with assumptions of most land structures such as mountains or volcanoes which have commonly had the steepest part be in the Northeast, as this fact can be support by geological evidence and the movement of the plate tetonic and the convergent boundaries that border most of the mountains on the planet earth.

Mangrove forests play an important role in _______. A. Fisheries b. Coastal protection c. Wildlife habitat d. All of the above.
Mangroves swamps or forests are productive wetlands and grow in saline and humid climates. They play an important role in fisheries, coastal protection and wildlife habitat.
What is the importance of mangrove forests?The mangroves are located in the subtropical and the tropical region where the climate is high in humidity and have saline and waterlogged forests.
The mangroves interact with the ecosystem through various means and help other aquatic organism for shelter and reproductive sites.
They help the ecosystem in maintaining water quality and help in coastal protection along with aiding the wildlife habitat. The fishes reside in the roots and the forests structures and lay their eggs.

What is an adaptation? Pick one.
a structural, behavioral, or physiological trait that enhances an organism's ability to survive and/or reproduce
the process during which light energy from the Sun is used to convert carbon dioxide and water into oxygen and food
the process through which organisms with advantageous structures or behaviors are naturally selected over organisms that do not possess these traits
a physical or behavioral characteristic that has stood the test of time and is still present after generations of other evolutionary changes
Adaptation is the process through which organisms with advantageous structures or behaviors are naturally selected over organisms that do not possess these traits.
What are the functions of traits?A trait, as related to genetics, is a specific characteristic of an individual. Traits can be determined by genes, environmental factors or by a combination of both. Traits can be qualitative (such as eye color) or quantitative (such as height or blood pressure).
Biological traits describe species' physiology, morphology, life history, and behavior, capturing both inter-specific interactions and the connections between species and their environment.
All living things have certain traits in common: Cellular organization, the ability to reproduce, growth & development, energy use, homeostasis, response to their environment, and the ability to adapt. Living things will exhibit all of these traits.

Explain how ecosystem services link rural lands with urban lands?.
Ecosystem services link rural lands with urban lands because people living in urban lands need resources that only come from rural areas such as crops, clean drinking water, fertile soil, and trees. ... Humans use forest land for harvesting wood, wildlife, fish, nuts, and other resources.
The advantages that come from ecosystems to people are called ecosystem services. Clean air and water, food production, and recreational activities are just a few of these advantages.
What is ecosystem?An ecosystem is a region where a bubble of life is created by plants, animals, and other organisms interacting with the weather, environment, and other factors.
First, rural lands offer crucial ecosystem services that are necessary for metropolitan regions to function.
Second, urban regions can provide rural areas with crucial ecosystem services.
Urban areas, for instance, might offer markets for agricultural products as well as financial and technological support for sustainable agricultural methods.
Third, the viability of both urban and rural communities depends on their connections. The movements of materials, energy, and information that unite urban and rural areas create a connection between them.
Finally, ecosystem services act as a vital link between rural and urban areas.
Thus, this way, ecosystem services link rural lands with urban lands.

Given what we know, we can confirm that the basic idea resulting from these studies is that a creature's metabolism is related to its lifespan.
How is metabolism related to lifespan?From the studies done and the comparison of the lifespan of certain species in relation to their metabolic rates, scientists have noticed that metabolism and lifespan are inversely proportional. The slower the metabolism of an organism, the longer that organism can live.
Therefore, we can confirm that the basic idea is that a creature's metabolism is inversely proportional to its lifespan, meaning that the faster the metabolism, the shorter the lifespan of the creature in question.
