Explanation:
why cell size remain small even though organism size is large
Answer:
Cell size is limited by a cell's surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes. A cell's function is determined, in part, by its shape.

How would the environment impact a multifactorial trait like height in someone with normal genetic variation? How would environment impact someone with a mutation that results in dwarfism?
Answer:
Explanation:
On someone with a normal genetic variation, the environment helps them adapt and pushes for the evolution of the traits that will help that species increase their chances of survival in future generations. This includes traits such as height, thus increasing this trait so that the species is able to reach food in higher places or reach higher places in order to find shelter. This does not have the same effect when dealing with a certain genetic mutation such as dwarfism since the mutation targets a specific value for these traits and is not affected by its environment.

What are grassroots movements?A grassroots movement is one that uses the people in a given district, region or community as the basis for a political or economic movement.
Grassroots environmentalism is that element of the wider environmental movement that engages in forms of contentious politics to develop knowledges about environmental issues, challenge examples of environmental destruction.
Grassroots groups can develop new solutions for existing problems and make use of both local governments and citizens for this. In both resource-rich and resource-poor contexts, grassroots organizations can develop an alternative neighbourhood-based voice.

The nucleotide sequence encoded in a gene defines the
that make up proteins.
Answer:
amino-acids
Explanation:
The process by which the nucleotide sequence in a DNA template is used to synthesize a complementary RNA is known as 'transcription', while the process by which this messenger RNA (mRNA) template is converted into an amino acidic chain in a protein is known as 'translation'. During transcription, the DNA template is read by an enzyme named RNA polymerase that synthesizes a complementary single-stranded RNA sequence called primary transcript (precursor mRNA), which is subsequently processed to yield a mature mRNA. On the other hand, during translation, this resulting mature mRNA is read by codons composed of triplets of bases (3bp). These triplets (codons) are read by using the genetic code which defines how the mRNA sequence will be specifically translated into 20 types of amino acids (with exception of stop codons TAA, TAG, and TGA) in order to form the polypeptide chain.

An experiment is designed to study the mechanism of sucrose uptake by plant cells. Cells are immersed in a sucrose solution, and the pH of the solution is monitored. Samples of the cells are taken at intervals, and their sucrose concentration is measured. The pH is observed to decrease until it reaches a steady, slightly acidic level, and then sucrose uptake begins. Rank the steps from first to last. To rank items as equivalent, overlap them.
A proton Pump, using ATP, pumps protons outside.
Sucrose moves into the cell.
H+ moves down electrochemical gradient into the cell.
A steady proton gradient with a higher concentration of H+ out of the cell is maintained by the proton pump.
pH decreases.
The gradient becomes sufficient.
Answer:

H+ moves down electrochemical gradient into the cell; Sucrose moves into the cell.
Explanation:
A proton Pump, using the energy of ATP hydrolysis, pumps protons outside the cell.
A steady proton gradient with a higher concentration of H+ out of the cell is maintained by the proton pump.
The continues outward pumping of protons by the proton pump causes the pH of the extracellular fluid to decrease
At some point the gradient becomes sufficient, and pH reaches a steady slightly acidic level.
H+ moves down its electrochemical gradient into the cell together with Sucrose through the hydrogen ion-sucrose co-transporter.
To rank items as equivalent, overlap them.

A) A proton Pump, using ATP, pumps protons outside.
D) A steady proton gradient with a higher concentration of H+ out of the cell is maintained by the proton pump.
F) The gradient becomes sufficient.
A co-transporter also called a symporter, is a carrier protein that transports a solute and an ion from one side of the membrane to the other at the same time.
The proton pump is an integral protein that builds a proton gradient across a biological membrane.
The cell cannot import sucrose by simple diffusion, the cell expends energy to move the substance against a concentration gradient.
The sodium and potassium maintain the electrochemical gradient of living cells, the direction an ion moves across a membrane is determined by the electrochemical gradient.

If we consider the challenges posed by the Great Plate Count Anomaly, what is the primary advantage of using culture independent techniques in microbiology?
Culture independent techniques is simply the use of methods in microbiology that are not based on or relies on cultivation inorder to study a microorganism in a defined ecosystem.
Independent based techniques offer a variety of advantages over the culture dependent methods.
The primary advantage of using culture independent techniques in microbiology is that culture independent techniques has the ability to identify or point out a large proportion of the microbial diversity readily and that identification on a normal state will be difficult to be observed using culture based studies or culture independent techniques.
The explanation regarding the primary advantage of using culture independent techniques in microbiology is described below;

What does speed mean?Speed is defined as the distance that is allegedly covered in a given amount of time. It is regarded as the speed at which anything is said to move.
In this instance, speed is estimated as 1/2mv2.
As a result, the variables for calculation are:
If the bottle is moving at 2 m/s, then
= ½ (0.250) (2) ^2
= 0.5
If the bottle is moving at 3 m/s,
= ½ (0.250) (3) ^2
=1.125
If the bottle is moving at 4 m/s, then
= ½ (0.250) (4) ^2.
= 2
If the bottle is moving at 5 m/s, then
= ½ (0.250) (5) ^2
= 3.125
= ½ (0.250)(6)^2
=4.5

What does the ATP molecule transfer to the sodium potassium pump?
Answer:
Using the energy from ATP, the sodium-potassium moves three sodium ions out of the cell and brings two potassium ions into the cell.
The pump binds ATP and three sodium ions to the cytoplasm where ATP then phosphorylates the pump and it changes shape, opening an opening to the outside of the cell and sodium is released and two potassium ions are taken up .
What is Sodium potassium pump?A sodium-potassium pump is defined as an enzyme found in the membrane of all animal cells where it performs many functions in cell physiology. The Na⁺/K⁺-ATPase enzyme is activated. For every ATP molecule used by the pump, three sodium ions are exported and two potassium ions are imported.
In this Na+ K+ pump which is an electrogenic transmembrane ATPase which was first discovered in 1957 and is located in the outer plasma membrane of cells; on the cytosolic side. The Na+ K+ ATPase pumps 3 Na+ out of the cell and 2 K+ into the cell for every ATP consumed.
Thus, the pump binds ATP and three sodium ions to the cytoplasm where ATP then phosphorylates the pump and it changes shape, opening an opening to the outside of the cell and sodium is released and two potassium ions are taken up.
