Heavy metals are harmful and should not be consumed in large amounts. Therefore, option (A) is correct.
What are harmful effects of heavy metal in water?The flow of groundwater and surface water, as well as seepage and runoff from the surface, can introduce heavy metals into private wells. People who consume significant quantities of heavy metals put themselves at risk for acute and chronic toxicity, as well as anemia, cancer, and damage to their liver, kidneys, and intestines.
Heavy metals in water are usually treated using methods like chemical precipitation, flotation, adsorption, ion exchange, and electrochemical deposition. Most of the time, heavy metals are taken out of inorganic effluent by a process called chemical precipitation.

An animal leaves its footprint in wet mud, and later, when the mud dries, the footprint can be filled with plaster. When the plaster hardens, it has
same shape as the foot of the animal. The plaster cast could then be used to make new footprints in soft mud identical to those made by the animal. The
process of using the plaster cast to make new footprints most accurately models
translation of mRNA codons to form a protein.
transcription of mRNA from the original DNA code.
insertion of nucleotides into the mRNA codons
deletion of nucleotides from the tRNA anticodons.
Answer:
The process of using the plaster cast to make new footprints most accurately models transcription of mRNA from the original DNA code
Explanation:
Transcription is a process in protein synthesis that takes place in the nucleus. During transcription, the DNA of a gene is used as a template to make an RNA molecule. In the process, nucleotide bases which are complementary to those found in the DNA molecule pairs with the DNA bases in a process called complementary base-pairing. However, Uracil is the nucleotide base that binds to adenine in the mRNA instead of thymine. An enzyme called RNA polymerase II catalyzes the formation of a mRNA molecule. Three steps are involved in transcription:
Initiation- is the beginning of the transcription process when RNA polymerase binds to DNA.
Elongation- addition of nucleotides to the RNA strand.
Termination- is the end of the process whereby RNA strand detaches from DNA template. The resulting mRNA is a single-stranded copy of the gene.
It models the transcription of mRNA from the original DNA code.
The process of using the plaster cast to make new footprints most accurately models the transcription of mRNA from the original DNA code because both have exactly the same type of materials.
Transcription is the process in which the information present in a strand of DNA is copied into a new molecule of messenger RNA which serve as a blueprints for protein synthesis during the process of translation. The mRNA has all the information that is present in the original DNA so we can conclude that it models the transcription of mRNA from the original DNA code.

67. Obligate anaerobes
68. Aerotolerant anaerobes
69. pH
70 media nutrient density
71. agar concentration
72. extremophiles
Explanation:
Anaerobes are microorganisms which do not require oxygen for their metabolic activities. The types of anaerobes based on metabolism are: obligate anaerobes; facultative anaerobes ; and aerotolerant anaerobes.
Some bacteria are anaerobes.
67. Obligate anaerobes do not require oxygen at all for their metabolism. They die in the presence of oxygen.
68. Aerotolerant anaerobes do not require oxygen as well but can also tolerate oxygen. they are unaffected by the presence or absence of oxygen
69. The pH of the medium affects the growth of bacteria. When pH becomes too low or too high, bacteria colonies begin to die.
70. when the nutrient concentration is high, growth rate of bacteria colony increases, but when it is low, bacteria colony growth decreases.
71. agar concentration limits the growth of bacteria colony. When the agar is very concentrated, that is the medium is hard, the bacteria colony is limited in their ability to move and vice versa.
72. Extremophiles is the name given to archaea that thrive in extreme conditions of temperature and pH. For example, the archaeal Methanopyrus kandleri strain 116 grows at 122 °C while the genus Picrophilus e.g., Picrophilus torridus has the ability to grow at a pH of 0.06.

10. Which type of telescope is known to be difficult to keep aligned?
rotating
refracting
reflecting
radio
Explanation:
Larger lenses are heavier, and tend to sag under their own weight, ruining the image quality as the lenses distort. The long mounting tubes are hard to make mechanically stiff, and so they tend to flex under the weight of the lens, making it hard to keep the optics in alignment.
The different types of telescopes include refracting telescopes, reflecting telescopes, radio telescopes, and rotating telescopes.
The refracting telescope was used by Galileo to discover the mountains and valleys on the moon.These refracting telescopes required long lenses in order for the light to focus properly.However, these long lenses made the telescope heavy.Because of their heaviness, it becomes difficult to keep refracting telescopes aligned.Hence, the correct answer is refracting telescopes.

Unstained cells have very little contrast. What single adjustment could you make to your microscope that would make cells easier to see at the same time while reducing the evaporation of your sample?
Answer and Explanation:
Microscope objects have thermal profiles. These profiles differ as a purpose of their physical parameters. Most objects are sold and designed for the resolution of fixed cell microscopy.
There is little indication that the temperature cycle affects the strain characteristics. A large box can be constructed around the microscope and heated with hot air.
The heating system's cycling causes the specimen to drift out of focus and can also change the coverslip position.
The microscope can be equilibrated to a single temperature to eliminate the movement resulting from the thermal expansion of the microscope's components.
Air currents connecting the specimen chamber should also be reduced—tight control of temperature for the entire laboratory and microscope. Any change in the temperature can lead to unwanted movement in the microscope. Heating ducts often produce localized temperature changes.

Which of the following describes a non-sense mutation?
A.Base pair change results in a premature stop codon; protein is nonfunctional.
B.Base is changed but the resulting amino acid is the same as in the non mutant DNA. No outward changes
.
C.A base is either added or deleted and causes the codons to be read incorrectly.
D.Base pair change results in a different amino acid; this may or may not affect the protein that result.
Answer:
A.Base pair change results in a premature stop codon; protein is nonfunctional.
Explanation:
Mutation, generally, refers to any change that occurs to the genetic sequence of a DNA. It can occur in different forms, hence, has different types. One particular type is the base pair substitution mutation, which involves the replacement of one or more nucleotide base by another in a sequence.
Base pair substitution can either result in one of the following namely: silent, missense, and nonsense. In NONSENSE mutation, the replacement of bases in the sequence causes the translation process to stop because a STOP CODON is prematurely encountered. Hence, the protein is non-functional.
Human growth hormone (HGH) is necessary for growth during human adolescence. Pituitary dwarfism is a condition that results from the inability of a person to produce HGH. Luckily, the human gene for HGH can be inserted into E. coli bacteria, which are able to make our HGH. The resulting HGH is used by people who are unable to make their own. What property about hereditary information makes this possible
Answer:
The correct answer is - DNA is a genetic language that is common and uses by every organism including humans and bacteria.
Explanation:
DNA is the unit of heredity and present in almost every living organism, it carries the genetic information and transfer from generation to generations. In this process of transfer of the genetic information, there are two processes transcription and translation helps to produce protein.
The ability to produce proteins with the help of DNA for the particular function as said in question which is HGH production. Correcting the abnormality of not able to produce HGH, to produce the normal protein with the help of putting human genes into Bacteria as DNA is universal genetic language.

Describe the movement of oxygen molecules if there were more oxygen molecules
outside the cell
Explanation:
Because there's a higher concentration of oxygen molecules outside the cell compared to the cell's cytoplasm, you'll see that oxygen diffuses into the cell along this concentration gradient. ... Because the molecules are moving at random, some will move out of the cell, but most will be moving in in this case.
Transporation is the mechanism by which the molecules and enzymes move in and out of the cell. When more oxygen is present outside the cell diffusion will occur along the concentration gradient.
What is diffusion?Diffusion is a transportation mechanism that involves the movement of the ions and the molecules from the high concentration area towards the low concentration region.
The high amount of oxygen present outside the cell will diffuse through the cell membrane inside the cell along the concentration gradient so that the concentration inside and the outside achieves equilibrium.
Therefore, the movement of the oxygen molecules from high concentration to low is diffusion.

The glucose transporter used by cells to obtain glucose from the media is a protein embedded in the membrane. When researchers first started to investigate the glucose transporter's structure they had trouble because it seemed to have 2 differnet shapes! Eventually they realized that the glucose transporter changes shape as it moves glucose into the cell but does not require energy to do it's work. Which of the following is the best description for the glucose transporter?
a. It's a carrier protein doing facillitated diffusion
b. It's a carrier protein doing active transport
c. It's a protein channel doing facillitated diffusion
d. It's a protein channel doing active transport
Answer:
a. It's a carrier protein doing facillitated diffusion
Explanation:
Facilitated diffusion may be defined as the transportation of molecules from a high concentration to a low concentration that is down the concentration gradient without input of the energy. Whereas the active transport is transportation of the molecules from the low concentration to the high concentration which is against concentration gradient by the membrane protein.
The glucose transportation process requires membrane protein for the transport and does not require any energy. Therefore, it is carrier protein which is doing the facilitated diffusion.

HURRRRYYYp
Answer:
The first statement is true, while the second statement is false.
Explanation:
Every living organism needs a particular amount of food in order to be able to survive. Each species though has its own different requirements, and there are great variations that occur because of size, lifestyle, is the organism cold-blooded or warm-blooded, etc.
In this case, we have to examples. In the first one, a single mouse needs 4 square meters of grass in order to stay healthy. In order to get the amount of grass needed for fifty mice, we just need to multiply the number of mice by the amount of grass needed for one of them:
50 x 4 = 200
We got 200, meaning that 200 square meters of grass will support a population of 50 mice.
In the other case, a single snake needs 10 mice in order to stay healthy. To get a result how many mice are needed for 10 snakes, again we just need to multiply the number of snakes by the number of mice a single snake needs:
10 x 10 = 100
We got 100, meaning that 10 snakes need 100 mice in order to stay healthy.

direction of an object's motion.
Answer:
True
Explanation:
Hope this helps:)
To solve this, we must be knowing each and every concept related to speed, acceleration and its calculation. Therefore, the given statement is false.
What is speed?Speed may be defined as the distance traveled by an item in the amount of time it requires to travel that distance. In other words, it measures how rapidly an item travels but does not provide direction. The term "velocity" refers to the combination of direction and speed.
Acceleration is defined by the rate at which an object's velocity changes with respect to time. When an object's velocity changes, it is referred to as accelerating or to have acceleration. Speed does not include the direction of an object's motion. Acceleration include the direction of an object's motion.
