Which option identifies ways that people positively affect Earth’s resources?
Answer:
c is the correct answer on EDGE2020
There are many ways by which humans can positively impact Earth's resources. These include reforestation, reducing pollution, protection of endangered species, and mindful use of water and attempts to replenish the water bodies, etc.
What are the earth's resources?The resources present on earth which were not formed due to any kind of human intervention are called earth's resources or earth's natural resources. There are various natural resources found on earth.
Energy resources like petroleum and natural gas, metallic resources like iron, copper, and gold, and nonmetallic resources like granite, sandstone, etc are some of the examples of various resources found on earth.
However, due to the rise in consumerism, these resources are being overexploited by humans which have resulted in their depletion.
But, the awareness of this is spreading fast and humans have adopted various measures to prevent negative impacts and induce positive impacts on the resources of the earth.
Therefore, humans can have a positive impact on Earth's resources.

Well this isn’t biology this is earth science but it doesn’t have the option.... 1. What geologic processes must have occurred for fossil ammonites (relatives to the nautilus that dominated oceans hundreds of years ago) to now be found in rocks at the highest mountains on Earth??
2. What would our planet look like if it contained no radioactive isotopes within it? What would it look like if radioactivity were producing twice as much heat within Earth’s interior?
The answers are that the geological process responsible for fossils being found on high mountains today is called Orogeny Tectonics. With no radioactive isotopes, the Earth's geography would be vastly different and void of life. If radioactivity produced twice as much heat the earth would become unstable.
The discovery of fossil ammonites within rocks at the highest mountains on Earth is due to orogenic plate tectonics. Plate tectonics is the name we use to describe a process in which pieces of the earth's crust move and often slam into each other, causing one of these to pile onto the other.
This can lead to the formation of mountains and mountain ranges. This process helps to explain why fossils of ammonites known to dwell in the ocean can be found in mountains.
Radioactive isotopes, or better yet, the decaying of radioactive isotopes, are responsible for generating most of the Earth's internal heat. The internal heat of the earth is the driving force of plate tectonics and without it, much of the geological activities responsible for the earth's current geography would not have happened.
Mountain ranges would not have formedPlate tectonics would not have caused the formation of the continents we know todayThe earth would lack a magnetic field to defend against ionizing radiation from the sunLife would likely not have evolved.Radioactive isotopes were vital in allowing for the conditions of the earth at the time that life evolved, and the heat they produce allows the earth to have a molten core and thus generate a magnetic field for protection.
Now, if the heat produced by radioactive isotopes were to double, the Earth's internal temperature would nearly double. Since this heat is the driving force for plate tectonics, we can expect a sharp increase in the number of earthquakes and volcanic eruptions. These can, in turn, cause tsunamis and changes to the earth's global temperature. Mountains would form continuously and continents may break apart. This instability would make life on earth's surface improbable.
Therefore, the geological process responsible for fossils being found on high mountains today is called Orogeny Tectonics. Without radioactive isotopes, the Earth's geography would be vastly different and void of life. Radioactivity producing twice as much heat would make the earth very unstable.

Explanation:
True or False: Within the body, all atoms combine to form molecules. If false, why?
Answer:
True
Explanation:
Two or more atoms combine to form a molecule, like how the water molecules, proteins, and sugars are found in living things.
Hope this helps! （づ￣3￣）づ╭❤～
The statement i.e. ''Within the body, all atoms combine to form molecules'' is true.
Atoms combine together to form molecules because atom is unstable substance which can't stay in single form due to its reactive nature but become stable when they form molecules due to filling of outermost shell and attain the electronic configuration of noble gases so we can say that atoms formed molecules in order to attain stability and can not remain individually.

The following events are part of a negative-feedback mechanism. I. blood pressure increase II. receptors detect a low blood pressure III. control center compares actual pressure with the set point IV. the heart beats faster Choose the arrangement that lists the event in the order they occur.
Answer:
II, III, IV, I
Explanation:
Blood pressure regulation is an example of negative feedback mechanism. When the blood pressure is low, sensor in the blood vessels called baroreceptors detect this and send a signal to the control center which is the hypothalamus.
The hypothalamus compares the current blood pressure with the normal and proceeds to send signals to the heart, as well as blood vessels and kidneys. The heart begins to beat faster, thereby increasing the heart rate and a a result, blood pressure goes back up to normal.
Over the period of a few days, a hospital receives an overwhelming increase in the number of patients with food poisoning. How would a scientist respond to this increase in sick patients?

Explanation:
In part A, you analyzed genes that contribute to two diseases. (cystic fibrosis and muscular dystrophy) How can scientists use this information to develop new treatments for these diseases? Based on your findings, do you think that scientists will need to develop multiple treatments to control symptoms of these diseases? Explain your reasoning.
Answer:
By designing suitable gene therapies in order to restore target gene expression.
Explanation:
Cystic fibrosis and muscular dystrophy are inherited genetic disorders associated with serious health problems. Cystic fibrosis is caused by mutations in the gene that encodes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein, and it is a condition associated with abnormal production of sticky mucus that leads to problems in the lungs and the digestive systems. On the other hand, muscular dystrophy is produced by mutations in genes localized on the X chromosome such as, for example, the gene 'dystrophin'. Gene therapy is an experimental approach used to compensate abnormal gene function by introducing exogenous genetic material and thus restore their altered protein products. Consequently, personalized gene therapies can be useful to treat inherited disorders such as cystic fibrosis and muscular dystrophy.
explain the reason for the variation in production by referring to the possible causes for variation in a population
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

Type your response in the box. Many countries have laws that regulate hunting, including restricting hunting to specific times of year. Why is this hunting restriction important for preserving certain animal populations?
Answer:
You can only hunt dear (example) for only sertin times of the year because when the doe's have their fans people want them to get big before they shoot them
Answer:
Animal populations can change from one season to another, so it’s important to restrict hunting to seasons when the population is high. Such a restriction helps prevent a severe drop in population, which could threaten the species. It’s also important to limit hunting during breeding seasons to increase the possibility of offspring reaching adulthood.

Answer:
D. Each enzyme can catalyze a wide variety of different reactions
Explanation:
Each enzyme can only catalyze a few, specific types of reactions.
Since enzymes and substrates are very specific to one another, enzymes cannot catalyze a wide variety of reactions.
If a substrate is not the correct one that fits in the enzyme's active site, a reaction will not occur.
So, each enzyme can only assist in a few reactions.
The correct answer is D. Each enzyme can catalyze a wide variety of different reactions
