Answer:
Deletion of two nucleotides.
Explanation:
Every amino acid coded by 3 nucleotides.
12:3=4 (amino acids)
6:3=2 (2 amino acids)
3:3=1 (1 amino acid)
After all of these mutations sequence amino acids change, but after continues stay the same.
Only deletion of 2 nucleotides will completely altered all amino acids encoded without mutation.
A frameshift mutation, altering all subsequent amino acids, can be caused by the deletion of two nucleotides or the insertion of a number of nucleotides not divisible by three.
Explanation:In the context of DNA sequencing, a mutation that changes all amino acids following the point of mutation is characterized as a frameshift mutation. This type of mutation is caused by the insertion or deletion of nucleotides in a DNA sequence that is not divisible by three. The options which could cause a frameshift mutation are either a deletion of two nucleotides or an insertion of a number of nucleotides not divisible by three (for instance, an insertion of six nucleotides would not cause a frameshift mutation as it's divisible by three, but an insertion of twelve nucleotides also wouldn't cause a frameshift mutation for the same reason). Thus, the correct answer would be a deletion of two nucleotides.

D. They show how certain compounds and elements move through the environment and are continually used and recycled
Please help!!
Answer:
D. They show how certain compounds and elements move through the environment and are continually used and recycled
Explanation:
The biogeochemical cycles are the cycles through which the chemical compounds are moving through the different spheres, both abiotic and biotic, and they get constantly used and constantly recycled through them. This basically means that the biogeochemical cycles are the ones that occupy every sphere, as they are what units all of the spheres. By moving through all of the spheres, the chemicals change their composition, getting used, dissolved, merged with other chemicals, and at the end they get recycled and the process continues all over again.

In the town of Edmonton, a breeze blows from the north during the day and toward the north in the evening. What is most likely located to the north of Edmonton?
A.
a desert
B.
a mountain range
C.
an ocean
D.
a forest
Answer:
C. an ocean
Explanation:
You should already know that the breeze leaves the place with the highest pressure and cold air towards the place with the lowest pressure and the warmest air. This movement is done as a way to balance pressure and temperature between these two locations.
During the day, the ocean is the place of great pressure and cooler air, so it is common that at that moment the breeze comes out of the ocean towards the terrestrial portion of the planet. However, at nightfall, the pressure of the ocean becomes lower and the air warmer than that of the land. The breeze at that moment makes the opposite way, leaving the land towards the ocean.
For this reason, we can say that the letter C is the correct answer to your question.

How do cells in a multicellular organism become specialized?
Answer: Cell specialization or cell differentiation is a process of converting generic cells in the body into specialized cells. The specialized cells can perform a certain function within the body. The cell specialization occurs in two stages of a multicellular organism.
i hope this helps yu can probaly find more on https://pediaa.com/how-do-cells-become-specialized/ :)
Answer:
Cells becomes specialized through cell differentiation
Explanation:
Cell differentiation is the process by which the cell in a multi cellular organism gets differentiated.
Basically the function of a cell is determined by DNA. During cell division identical cells are produced with varied genetic identity and this "variation in genetic identity" causes different cells to perform different function. The DNA of a cell with specific genetic area is expressed based on the functionality of the cell irrespective of the expression of entire DNA areas.

After three half- lives, a sample contains 10 grams of parent isotopes. How many grams of the parent isotope were present to start?
its not for biology..... its for Earth/Space Science
Answer: Initial amount of parent isotope present in the sample was 80 grams.
Explanation: Initial amount was= 80 grams
The sample undergone radioactive decay and after first half-life, it has= 40 grams (half of initial amount)
after second half-life, it has= 20 grams
And after third half-life, it has= 10 grams
Thus, the sample at present has 10 grams and initially had 80 grams of the parent isotope materials.
Answer:
The answer is 80
Explanation:
a half lives takes away half of an amount, in the question it said 3 half- lives.
the only posible answer is 80.
FIRST half lives: 80-40=40
SECOND half lives: 40-20=20
THIRD half lives: 20-10=10
80 is the only way to get to 10 with three half-lives.

Answer:
C. The populations of all other organisms in the food web would decrease because there would be less energy.
Explanation:
In the Arctic ecosystem, phytoplankton is producers which synthesise food with the help of sunlight. In this ecosystem, zooplankton and krill are primary consumers as they feed on phytoplankton.
Arctic cod and bowhead whale are secondary consumers which feed on primary consumers. In the arctic ecosystem, the temperature is rising which is killing the phytoplankton.
If the phytoplankton population decreased, then all the consumers in the food chain in this ecosystem would decrease due to lack of food.

George Brooks and his colleagues found that pyruvic acid produced through glycolysis can be used in aerobic respiration or converted to lactic acid in muscle cells, with lactic acid later being reconverted into pyruvic acid for further energy production. These findings have significant implications in athletic training, helping athletes understand how to manage lactic acid build up and utilize metabolic processes for optimizing muscular performance.
Explanation:George Brooks and his colleagues completed research into lactic acid in muscle cells. This research discovered that during exercise, pyruvic acid, formed as a product of glycolysis, can either be used in aerobic respiration or converted to lactic acid. This process involves the enzyme lactate dehydrogenase (LDH).
It was initially thought that an accumulation of lactic acid caused symptoms such as muscle stiffness, fatigue, and soreness. However, newer research conflicts with this. Now, it's understood that once lactic acid has been removed from the muscle and circulated to the liver, it can be reconverted into pyruvic acid and catabolized further for energy.
One significant application of these findings in the field of athletic training is understanding that in the absorptive state following intensive exercise, muscle cells can convert excess glucose to glycogen for storage. Additionally, amino acids are utilized in synthesizing actin and myosin, the proteins responsible for rebuilding muscle fibers.
Furthermore, understanding these metabolic processes in muscle fibers can help devise methods of training and recovery that optimize muscular performance. This understanding can also help individuals increase muscle endurance and delay fatigue by managing the buildup and removal of lactic acid in muscle cells during and after exercise.
