Answer:
This question lacks options, the options are:
A) THC ATS AWT HER AT
B) CAT THE SAW RAT THE
C) EHT TAC WAS EHT TAR
D) THE THE CAT SAW THE RAT
The answer is A
Explanation:
Mutations are generally any change that occurs to the nucleotide sequence of a gene. However, a FRAMESHIFT Mutation is a kind of mutation that changes/alters the reading frame of the nucleotide sequence. Frameshift mutations are caused when either a DELETION (removal of nucleotides) OR INSERTION (addition of nucleotides) MUTATION occurs.
In this question, Ji wants to write an example of a frameshift mutation using the following sentence: THE CAT SAW THE RAT. A frameshift mutation will delete or add nucleotide bases to the sequence. Hence, the sequence: THC ATS AWT HER AT best represents frameshift mutation because a deletion mutation has altered the reading of the sequence in three's.
Notice that the bases in options B, C and D are still read in three's.
Answer:
THC ATS AWT HER AT.

What is a clue that the lac operon is on?
A.)Lactose is absent.
B.)The cell membrane changes.
C.)The repressor protein has fallen off the molecule.
D.)RNA polymerase is blocked by the repressor.
The correct answer is C.) The repressor protein has fallen off the molecule.
The lac operon is a regulatory system found in bacteria, which controls the expression of genes involved in lactose metabolism.
The lac operon consists of three main components: the structural genes (lacZ, lacY, and lacA), the promoter region, and the operator region. The regulation of the lac operon depends on the presence or absence of lactose and glucose.
In the absence of lactose, the lac repressor protein binds to the operator region of the operon, preventing the expression of the structural genes. This inhibits the production of enzymes involved in lactose metabolism.
However, when lactose is present in the environment, it acts as an inducer. Lactose is converted into allolactose, which binds to the repressor protein and causes it to undergo a conformational change. As a result, the repressor protein falls off the operator, allowing RNA polymerase to bind to the promoter region and transcribe the structural genes.
Therefore, the clue that the lac operon is on is the falling off of the repressor protein from the operator region, enabling gene expression and the production of enzymes required for lactose metabolism. Therefore, the correct answer is C.

Gross production is the amount of energy left after cellular respiration. Please select the best answer from the choices provided T or F
Answer:
FALSE
Explanation:
Gross production is the amount of energy left after cellular respiration that is false, as the gross production is the total production and the net production is the amount of energy left after cellular respiration.
What is the significance of the gross production?Gross production is the total amount of energy produced by an organism through different processes, such as photosynthesis, ingestion, and digestion of food, while after energy is used by the organism for cellular respiration, what is left is called the "net production." Although the gross energy is not released, the net energy is.
Hence, gross production is the amount of energy left after cellular respiration that is false, as the gross production is the total production and the net production is the amount of energy left after cellular respiration.

Ribulose biphosphate carboxylase is a chemical that aides in the process of photosynthesis. Ribulose biphosphate carboxylase breaks down carbon dioxide and bonds carbon atoms together to begin the formation of sugars. Without ribulose biphosphate carboxylase, photosynthetic organisms would not be able to produce as much food. Even though ribulose biphosphate carboxylase is involved in assisting chemical reactions, its chemical structure is unchanged.
Based on the information about the function of ribulose biphosphate carboxylase, what is the best classification of the chemical?
A.Carbohydrate B.Enzyme C.Lipid D.Nucleic Acid
Answer:
The correct answer is - B. Enzyme.
Explanation:
RubisCo or ribulose bisphosphate carboxylase is an enzyme and most abundant protein on the earth that catalyzes the formation of the sugars from the CO2 by the photosynthesis process.
As it is given that in absence of the RuBisCo enzyme the cells plants or the photosynthetic organisms are not able to produce as much food as they produce in presence which means it has an essential role in increase the photosynthetic process to produce the food. By this, we can say it is an enzyme that helps in the process of photosynthesis.

For this assignment, conduct some independent research on the raccoon and mountain gorilla. You may do your research online or from library books and magazines.
Part 1: Fill in the table below and then answer the questions.
Trait
How many offspring do they have in a year, usually? What do they eat?
Where are they found in the world?
How many are there in the world?
Are they hunted for meat, skin, fur, or other parts?
Part 2:
Which species is most vulnerable to extinction? Give at least three reasons why.
Which species would be most harmed by environmental change that wiped out one area of its habitat? Why?
Answer:
Raccoon:
1. Mother raccoons can have between two to five babies in a litter, and they will have just one litter per year.
2. Raccoons are omnivores, meaning they will eat both plants and other animals. This includes fruits, berries, nuts, fish, frogs, mussels, crayfish, insects, turtles, mice, rabbits, muskrats and bird eggs.
3. Raccoons can be found natively throughout most of the US and Canada, as well as in parts of Latin America, from Mexico extending down to the northernmost regions of South America.
4. There are only 323 to 955 left in the world.
5. They are hunted for their fur and skin.
Mountain Gorilla:
1. Once they have reached an age of approximately 10 years, female mountain gorillas give birth to one baby every 4 years.
2. They eat roots, shoots, fruit, wild celery, and tree bark and pulp.
3.Mountain gorillas are found in two separate locations: the Virunga range of extinct volcanic mountains on the borders of the Democratic Republic of Congo (DRC), Rwanda and Uganda, and in the Bwindi Impenetrable National Park in Uganda.
4. There are only about 1,000 mountain gorillas left.
5. Not only are they hunted for meat, mountain gorillas are also illegally hunted for trophies and live infants.
Part 2:
The mountain gorrila is most vulnerable to extinction. People hunt for mountain gorillas more than they hunt for raccoons. mountain gorillas are on the endangered list. Not only are the mountain gorillas hunted for their meat but they are killed as trophies. Raccoons are rarely out in the daytime making them harder to hunt.
The raccoons would be most harmed by environmental change. Raccoons live in trees and need places to hide in the day time. Gorillas would be able to adapt better considering they dont need to hide in the trees. Raccoons would then be out in the daytime making it easier for them to be caught.

Explain why hunter-gatherer societies were highly mobile.
PLEASE HELP!!!
Answer:
Hunter and gatherer societies were highly mobile because if the place they they were staying ran out of resources they would have to move. The way that later societies would combat this is by planting farms which could grow back every year and allow them to stay in one place for long periods of time. Hope that helped!
Answer:
Hunter Gatherers rely on the land around them to keep them alive and well, with this being said , if a heard of Buffalo were to move away the village would starve because their main food source would be gone, so they have to “follow their food” and move with nature to stay alive.

How are kettle lakes formed
Answer:
Kettles form when ice detaches from a glacier. Eventually, it becomes wholly or partially buried in sediment and slowly melts, leaving behind a pit.
Answer:
A kettle lake is formed when an inactive block of ice breaks off of a glacier, as time goes on it gets buried sediment and begins to melt, as it melts it leaves behind a pit. Where eventually water will fill it up and the pit will become a body of water.
Again, imagine that your liver, which has a volume of 2 liters, developed from a single embryonic precursor cell with a volume of 1000 μm3, or 1 x 10-12 liters. You previously calculated how many cell division cycles would be required for the precursor cell to produce your mature liver.
What if the control of liver organogenesis were a bit faulty, and the process went exactly 2 cell division cycles beyond this? What then would be the volume of your liver in liters?
I found that the answer to the first question is 41, but I can't figure out the second part.
Answer:
41 cycles
If cell division went 2 cell division cycle beyond the precursor; we have 43 cycles
The volume would be = 17.59 Litres
Explanation:
From the given information:
The number of cells in the liver that developed from an embryonic precursor is roughly [tex]\dfrac{2}{10^{-12}}= 2\times10^{12}[/tex]
The number of cell cycles needed to produce [tex]2\times 10^{12[/tex] cells is:
= [tex]log_2(2\times 10^{12})[/tex]
= 40.86
[tex]\simeq[/tex] 41
Thus, nearly 41 cycles of cell division are required to form the mature liver.
Now;
Suppose 2 extra cell division cycles took place;
The total number of cells would be 2⁴³ = 1.759 × 10¹³; &
The volume would be = 1.759 × 10¹³ × 10⁻¹²
The volume would be = 17.59 Litres
