Answer: However, bacteria can also cause disease. Examples of bacterial diseases include tetanus, syphilis, and food poisoning. Bacteria may spread directly from one person to another. For example, they can spread through touching, coughing, or sneezing. Some Eubacteria can induce serious diseases such as tuberculosis, meningitis, anthrax, leprosy, cholera and tetanus. Antibiotics disrupt normal functioning of bacterial ribosomes or synthesis of the cell wall and prevent further multiplication of bacteria in the body.

Which best describes how to classify water?
A It is an element because it is made
from a pure substance.
В
It is a compound because it is made
of a single kind of molecule.
© It is a mixture because it is composed
of more than one molecule.
D It is a solution because it is a
homogenous mixture of different
compounds.
Answer:
D
Explanation:
Water is a compound and scientifically known as H[tex]_{2}[/tex]0 (2 hydrogen atoms and 1 oxygen). Therefore, the answer is...
Not A because water is not an element of one pure substance; rather, it is a compound and can be broken down into two pure substances.Not B because the statement contradicts itself: a compound is made of different atoms and, thus, different molecules.Not C because a mixture contains different substances that are physically -- not chemically -- combined. And as we know, water is a compound, which means that its atoms are chemically bonded to one another. Or else it would just be 2 free hydrogen atoms and 1 oxygen.D (yay!) because it is not the *most* accurate, but simply the best description of those provided. Water can be described as a homogenous (uniform in appearance) mixture because, minus the "mixture" part, that's what it is, essentially: a substance that looks pure but is really made of up different molecules.Ngl this was tricky, but I hope this helps :)

When is the production of genetically identical offspring a disadvantage? Explain your reasoning.
Answer: In an unstable or unpredictable environment asexually-reproducing species may be at a disadvantage because all the offspring are genetically identical and may not have the genetic variation to survive in new or different conditions. In an unstable or unpredictable environment asexually-reproducing species may be at a disadvantage because all the offspring are genetically identical and may not have the genetic variation to survive in new or different conditions.
Explanation:
The correct answer for the given question about Asexual Reproduction is "Production of genetically identical offspring is a disadvantage in an unstable or unpredictable environment".
What is Asexual Reproduction?Asexual reproduction refers to a type of reproduction when a child is born to a single parent. The newly created people are clones of their parents since they have the same genetic and physical characteristics.Both multicellular and unicellular species can reproduce asexually. There will be no gamete fusion involved in this procedure, and the number of chromosomes will remain the same. With the exception of specific situations where there is a possibility that a rare mutation may occur, it will inherit the same genes as the parent.So we can conclude that as all of the offspring are genetically identical and could not have the genetic variation to thrive in novel or changing environments, asexually reproducing animals may be at a disadvantage in an unstable or unpredictable environment.

1. Explain why the greenhouse effect is necessary but how an enhanced greenhouse effect can harm the planet.
2. Define global warming and explain what has caused the recent trend of warming that the earth is experiencing.
3. Explain why Earth's temperature is directly affected by the amount of greenhouse gases in the atmosphere.
4. Define carbon sequestration and explain how deep geologic burial of carbon works.
5 Describe the connection between fossil fuel burning, the melting of polar ice, and the rising of global sea levels.
Answer:
1. The enhanced greenhouse effect disrupts the Earth's climate equilibrium and has led to an increase in the global average surface temperatures.
2. Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect" 1 — warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping.
3. Greenhouse gases absorb some of the energy and trap it in the lower atmosphere. Less heat radiates into space, and Earth is warmer. ... Carbon dioxide, methane, water vapor, and nitrous oxide are naturally present in Earth's atmosphere.
4. Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide. It is one method of reducing the amount of carbon dioxide in the atmosphere with the goal of reducing global climate change.
5. As climate change caused by burning fossil fuels drives temperatures higher, the ocean warms, causing it to expand. ... Scientists have found that water draining from melting glaciers and ice sheets in polar and mountain regions is now also contributing to this rise in sea levels.
Answer: 1. Necessary because it keeps heat in and keeps the planet at the right temperature for life.
It can harm the planet if more pollution occurs and the greenhouse gas effect traps too much heat and causes global warming. 2. Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"1 — warming that results Greenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse. The greenhouse effect keeps Earth's climate comfortable when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping. 3. Human activities contribute to global warming by increasing the greenhouse effect. ... Greenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse. 4. Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide. It is one method of reducing the amount of carbon dioxide in the atmosphere with the goal of reducing global climate change. Geologic carbon sequestration is the process of storing carbon dioxide (CO2) in underground geologic formations. The CO2 is usually pressurized until it becomes a liquid, and then it is injected into porous rock formations in geologic basins. 5. As climate change caused by burning fossil fuels drives temperatures higher, the ocean warms, causing it to expand. This expansion in turn causes sea levels to rise. ... There is now so much warming baked in to the global climate system that sea levels will continue to rise for centuries.

Name and give examples of 2 major types of mutations. What do they have in common? How are they different?
Answer:
The correct answer would be - Two major types of mutations are deletions and substitutions.
Explanation:
The two major types of mutations are deletion and substitution, other than these there are many more mutations that are categorized under gene mutations and chromosomal mutation.
The deletion mutation takes place in the conditions where the DNA deletes or missed copying the nucleotide in a new DNA molecule. This type of mutation can occur in one or more nucleotides. Whereas Substitution mutation occurs when there is a wrong nucleotide added to the DNA sequence or substitute with other.
Both could be deleterious and takes place at the nucleotide level. Both mutation depends on the number of nucleotide or the location of the mutation on the gene.

How does the color adaptation help fish residing in the coral reefs?
Answer:
Fish found in coral reefs also have bright coloring to help with mating or camouflage. Due to the wide variety of prey found in coral reefs, the fish have developed a generalized feeding structure to take advantage of the biodiversity. Lastly sessile animals, such as coral, have adapted toxins to keep away predators.
Explanation:
Answer:
Many fish have color patterns that help them blend in with their environment. This may allow the fish to avoid being seen by a predator. Some fish, such as the flat fishes (Pleuronectiforms) , can change their skin coloration to match the surrounding habitat. Fish can also have disruptive markings to hide body parts

Researchers allow bees to feed from a feeder located 500 meters due south of the hive for several days in a row. They then place a new feeder due south of the hive and place feeders in several other directions from the hive as well, but all are now 450 meters from the hive. They leave the original feeder empty. Next, they determine which feeders that new bees from the hive now visit. What information can they learn from this experiment alone
Answer:
they can learn if Bees are able to calculate distance and direction or if they simply stick to what they know.
Explanation:
From this experiment they can learn if Bees are able to calculate distance and direction or if they simply stick to what they know. Since they have been accustomed to feeding from the feeder that is south they may continue to do so, but since it is not the farthest from the hive and there are other feeders located closer they may chose the new feeder. If they do decide to change feeder, then it tells the researchers that the Bees are able to calculate the distance and know that the new feeders are closer, while which feeder they choose might give them information on how bees determine direction.
The Tibetans and Han Chinese share several genetic traits and DNA. However, the EPAS1 gene, which increases the ability of red blood cells to carry oxygen even in low oxygen environments, is only commonly found in the Tibetan population that live in higher elevations. Explain why this gene is only common in Tibetan populations from the perspective of competitive advantage and natural selection. Write your answer in three to five sentences.(4 points)
Answer:
When in higher altitudes, ticker blond has a tendency to cause problems like heart attack's, however the Tibetans have adapted to the high altitudes and this has made their blood thinner in order to keep them safe in the altitudes, including that it has low oxygen rates in the altitude therefore providing more oxygen in the bloods cells.
Explanation:
:D It's not my best explanation but I hope this helps <3.
Owing to the fact that ability of the redblood cells to to carry oxygen even in low oxygen environments is neccessary at high elevations, the Tibetan population that live in higher elevations are found to possess the EPAS1 gene.
What is natural selection?The term natural selection refers to the fact that organisms that are better adapted to their habitat will live longer and reproduce. Now we have to note that owing to the elevation at which they live, the people that possess this EPAS1 gene can cope with oxygen stress that could likely occur at a high altitude.
As such, the Tibetan population that live in higher elevations are found to possess the EPAS1 gene.

How does the movement, diet, and cellular structure of an organism play a role in classification?
Centrosomes and lysosomes are found in animal cells, but do not exist within plant cells.
The lysosomes are the animal cell’s “garbage disposal”, while in plant cells the same function takes place in vacuoles.
Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells.
The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell.
The chloroplasts, found in plant cells, contain a green pigment called chlorophyll, which captures the light energy that drives the reactions of plant photosynthesis.
The central vacuole plays a key role in regulating a plant cell’s concentration of water in changing environmental conditions. follow me
