Answer:
7683.2 Joules
Explanation:
We can calculate potential energy using the equation that is used to calculate the work done by a conservative force, in this case, gravity.
U(x)gravity = mgy
U represents potential energy, m is mass, g is gravity, and y is the height.
U(x) = (80 kg)(9.8 m/s^2)(9.8m)
Potential Energy = 7683.2 Joules
Mistakes are sometimes made in duplicating or transmitting genetic information. These mistakes are called
Answer:
Mutation
Explanation:
Mutation is any alteration or change in the genetic sequence of a gene caused by mutagens (substances) or mistakes during replication of genetic sequences.
A mutation occurs in the gene from time to time, although, the cell has protocols in place to put them under control if they occur. However, when DNA or a gene is being copied and transferred to offsprings, there is bound for mistakes called MUTATION to occur.

What is RNA primase's job?
-removing a few bases for DNA polymerase
-add a few bases for DNA polymerase
-removing a few bases for helicase
Answer:
The correct answer is - add a few bases for DNA polymerase
Explanation:
A short extended nucleic acid composed of ssRNA molecule. This is a molecule that synthesize a primer initialy and later again lay down a primer after the opening of replication fork by DNA helicase.
It sysntheisze before and after the helicase and follow the helicase in order to prepare for the replication process. Thus, adding a few bases for DNA polymerase is main job of RNA primase.

What's the definition of absoulute dating
Absolute dating is the process of determining an age on a specified time scale in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty and precision. Absolute dating provides a numerical age or range in contrast with relative dating which places events in order without any measure of the age between events. In archeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates. Techniques include tree rings in timbers, radiocarbon dating of wood or bones, and trapped charge dating methods such as thermoluminescence dating of glazed ceramics. Coins found in excavations may have their production date written on them, or their may be written records describing the coin and when it was used, allowing the site to be associated with a particular calendar year.

If the sodium/potassium ion pump were to stop functioning, what would eventually happen to the concentration gradients of sodium and potassium ions across the membrane
Answer:
The correct answer would be - concentration gradient will reach to equilibrium.
Explanation:
If the Na+/K= ion pump stops working which is to pump the sodium and potassium ion across the cell membrane. The movement takes place in 3:2 ratio with the help of ATP.
Eventually, the concentration gradients of sodium and potassium would be equal and found equilibrium across the membrane. This equilibrium would be reached due to passive transport that occurs in either direction across the membrane.
The theory,of evolution states that all living things had a single common ancestor. The translation between mRNA and amino acids is the same for all living thing. Does the second statement support the theory of evolution ?
Answer: the theory of evolution states that all living things we can identify descend from the Last Universal Common Ancestor. It is not that the translation process between mRNA and amino acids is universal, but that the underlying genetic code relating DNA nucleotide triplets (codons) to amino acids is the same for almost all living things.
Explanation: The genetic code ‘tells’ mRNA which the sequence of amino acids in a protein and when to stop adding amino acids. The DNA . triplets, called codons, code for 20 amino acids and a STOP signal. The code is identical in almost all cases, but there are variation, mostly found in mitochondrial DNA. But even when these variants exist, most of the code is the same as in other living organisms. For example the codon AGG normally codes for the amino acid serine but in arthropod mitochondria it codes for lysine. These very few and minor changes tend to confirm the single ancestry of the code and how well it has been conserved through billions of replications

What is the medical term for the process or procedure that destroys or inhibits disease-causing microorganisms to prevent infection:
Answer: Sterilization.
Explanation:
Sterilization is the process that kills, or deactivates all forms of life so then a product is considered free of viable microorganisms. This process must be designed, validated and carried out to ensure that it is capable of eliminating the microbial load of the product.
Since sterility cannot be demonstrated without causing the complete destruction of the products, sterility is considered when the probability of a product being contaminated is acceptably remote. A critical product is considered sterile when the probability of a microorganism being present in an active or latent form is equal to or less than 1 in 1,000,000 (sterility safety factor 10^-6).
Agents that kill microorganisms are called microbicides or more commonly called "germicides". If the agent kills bacteria, it is called a bactericide. And if it kills fungi, then it is called a fungicide. It is important to consider than after an exposure of the sterilized object to the air or its surroundings, it will have become contaminated again with microorganisms.
Examples of sterilization include physical methods and chemical methods. Physical methods include:
Wet heat (in steam autoclave) Dry heat (in sterilization oven) Radiation (gamma radiatio, electron beam, X-ray, ultraviolet, microwave, white light)Chemical methods include a variety of chemicals in liquid and vapor form, for example:
Hydrogen peroxideChlorine dioxideOzone gasesEthylene oxidePropylene oxidePeracetic acidOnly answer if you know the answer
Answer:
B. A helicase enzyme unwinds the DNA molecule, then corresponding nucleotides are added to the separated original strand forming two separate semiconservative molecules
Explanation:
DNA Replication is an important phenomenon as far as cell division is concerned. It is the process whereby a DNA molecule doubles its content or forms two DNA molecules from one.
In the semi-conservative model of DNA replication, an enzyme called DNA helicase unwinds the double stranded DNA molecule into two single strands. The single strands are then used as template for DNA polymerase to synthesize another molecule of DNA. Hence, two separate DNA molecules comprising of one old strand and one new strand.

Which of the following is true about CO_2CO
2
?
A
It does not have much effect on the climate.
B
It is a greenhouse gas.
C
Very little CO_2CO
2
is being emitted now.
D
If we cut CO_2CO
2
emissions by half, the temperature will stop rising.
Answer:
B.
Explanation:
It has a huge impact on the environment
It is being emitted in large amounts
And if we cut our carbon emissions in half it would delay the risk of raising the global temperature of 1.5 degrees Celsius but half of it would still pumped into the atmosphere along with the carbon dioxide already in the atmosphere.
But it is a greenhouse gas because it helps trap the heat remaining in Earth's atmosphere which is why the Earth is warming.
CO2 is a greenhouse gas.
what are greenhouse gases?
Greenhouse gases are gases in the atmosphere that affect the energy balance of the planet. The greenhouse effect is caused by them. Carbon dioxide (CO2), methane, and nitrous oxide, the most well-known greenhouse gases, can all be present in low concentrations in the environment.
The greenhouse gases in the atmosphere trap heat and warm the earth.
Carbon dioxide, methane, nitrous oxide, and water vapor (all of which exist naturally) are the principal greenhouse gases, as are fluorinated gases (which are synthetic).
Carbon dioxide (CO2) is released into the atmosphere as a result of the combustion of fossil fuels (coal, natural gas, and oil), solid waste, trees, and other biological materials, as well as chemical processes (e.g., manufacture of cement). As part of the biological carbon cycle, carbon dioxide is absorbed by plants and released from the atmosphere.
hence, CO2 is a greenhouse gas.
