What is the best way to prevent contracting the influenza virus?
A.taking antibiotics B.getting a vaccination C.Drinking lots of water D.treating water supplies
Answer:
B. Getting a vaccination.
Explanation:
B. Getting A Vaccination
Influenza virus It is a respiratory virus because it infects the respiratory tract including the nose, mouth, bronchi and can even go further into the lungs to the alveoli and cause pneumonia. A person will spread the virus through coughing or sneazing that become airborne droplets. When a suceptible person comes in contact and breathes in these droplets, it causes an infection.

What happens when living things get in the dirt?
how do cells use oxygen during cellular respiration
Answer:
In cellular respiration, cells use oxygen to break the sugar molecule. That releases the energy which is then transferred to an ATP (adenosine triphosphate) molecule. ATP is the fuel that cells need for energy. And where does cellular respiration happen?

In a DNA strand, you find that 20% of the bases are Adenine. What percentage of the DNA would be Cytosine?
Answer:
Yes
Explanation:Since adenine is 20%, then thymine is 20% as well. The total of both is 40%. From 100 remains 60% which is divided equally between guanine and cytosine, so each is 30%.

Explanation:
Find out two types of water purification and name and describe them here.
Answer:
1. Reverse Osmosis
Reverse Osmosis works by forcing feedwater through a semi-permeable membrane.
A pump is used to apply pressure to reverse the normal osmotic flow across a membrane, meaning purified water molecules (permeate) are forced through the reverse osmosis membrane and recovered in preference to contaminants in the concentrated side which are left behind (reject concentrate).
2. Oxidisation
Oxidisation in the form of chlorination has been used as a means of water purification since the beginning of the last century. Hypochlorite is the key agent, achieving a disinfection of water by oxidising bacteria to eliminate waterborne diseases. Several different methods can be used to provide oxidation, including ozonation, chloramination, UV, bromination & chlorine dioxide. During the treatment, hydroxyl radicals are generated to destroy bacteria cells.

By using mutable collagenous tissue, what advantage do Echinoderms have?
Answer:
The properties of this connective tissue are mutable for a short period of time, under neural control, which provides certain mechanical advantages, which include the ability to maintain various postures without muscular effort; that is, it allows Echinoderms to change the consistency of the body, this is useful to escape predators or crawl along the seabed.
Explanation:
Echinoderms comprise the marine organisms known as starfish, sea urchins, sea cucumbers and sea lilies. These present, for the most part, benthic habits and are distributed from intertidal environments to deep bottoms and at different latitudes. They have a mutable collagenous tissue that allows them to change the consistency of the body, that is, they can rapidly change their stiffness and is involved in processes such as fission and autotomy. Some echinoderms quickly switch back and forth between being soft and stiff, which helps crawl along the seabed. Others twist only once from stiff to soft, letting a starfish cut off one of their arms to escape a predator, that is, they can drop an arm when attacked by a predator. When this happens it is called autotomy or autoamputation and the nervous system tells the mutable collagen tissue near the base of the arm to disintegrate. The wound heals and then the arm grows back, a process that can take weeks to months, depending on the species.
Answer:
saves energy
Explanation:
Mutable collagenous tissue is used to lock an Echinoderm into position.

Explain what is different about how genetic
information (DNA) is stored in prokaryotes and
eukaryotes? *
Answer:
The main difference between eukaryotic and prokaryotic cells is that eukaryotic cells have a nucleus.
The nucleus is where cells store their DNA, which is the genetic material.
The nucleus is surrounded by a membrane. ...
Explanation:
All prokaryotes are single-celled (unicellular) organisms.

Briefly describe the layers of the atmosphere:Troposphere-Exosphere-Stratosphere-Mesosphere-Thermosphere-
Answer:
Explanation:
-Troposphere. It is the lowest layer and encompasses the Earth's surface up to an average height of 12 kilometers; about 17 kilometers in the equatorial regions and about 9 kilometers at poles
- Stratosphere.Separated from the troposphere by the tropopause is this layer containing 19 percent of the atmospheric gases, but very little amount of water vapour.
-Mesosphere. It is located above the stratosphere up to a height of 80-85 kilometers in the mid-latitudes, where the mesopause is located.
-Thermosphere. From the upper limit of the mesopause extends the thermosphere, known as the upper atmosphere.
-Exosfera. It is the last layer, the outerest until connected with the solar wind.

Explanation:
The copper wire is cut into three pieces of unequal lengths. All three pieces of copper would have (1 point)
A the same mass
B the seſme physical properties
C different crystal structures
D different arrangement of atoms
B.) The same physical properties.
Also the copper wire would also have the same Chemical Properties. They wouldn't have a different arrangements of atoms because that would mean they are a different substance. They wouldn't have the same mass whereas they are now in 2 pieces. Copper is not a crystal meaning it would not have any crystal structures. That leaves the only applicable answer to be B. Also in case you need to find whether or not two identical substances are the same would be by testing the melting point, hardness and solubility. I just finished working on this section in my own 8th grade Science class so I think this should either help you now or later on.
Hope this helps.

Explain the relationship between codon and gene.
Answer:
A codon is a trinucleotide sequence of DNA or RNA that corresponds to a specific amino acid. The genetic code describes the relationship between the sequence of DNA bases (A, C, G, and T) in a gene and the corresponding protein sequence that it encodes. The cell reads the sequence of the gene in groups of three bases.
