How did the insertion of a nucleotide in a DNA sequence result in a phenotypic change in an organism
Answer:
if the nucleotide insertion occurs within the coding region of a gene (frameshift mutation), then it will change the open reading frame (ORF) of the resulting protein and thus also will alter the phenotype of the individual
Explanation:
A mutation is any change in the DNA sequence of the genome of a cell/organism. A point mutation is a genetic mutation where a single nucleotide is inserted, deleted or changed from the original DNA sequence. The insertion of a single nucleotide in the coding region of a gene is called frameshift mutation since this nucleotide base shifts the way the DNA sequence is read. A frameshift mutation changes the meaning of the codons that follow the inserted nucleotide base and thereby protein function is generally lost, thereby also affecting the resulting phenotype associated with this protein.
How quickly does the process of excretion occur in plants?
Explanation:
Plants produce two gaseous waste products i.e. oxygen during photosynthesis and carbon dioxide during respiration. Excretion of gaseous waste in plants takes place through stomatal pores on leaves. ... Excess of water is also excreted from the plant body through the stomatal pores and from the surfaces of fruits and stems.

Answer:
The study of evolutionary relationships that includes a branching pattern showing lineages diverging is called phylogenetic tree
Explanation:
The phylogenetic tree is composed of,
• Lineages → These are the taxonomic groups of interest placed in the extremes of the lines called branches.
• Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor.
• Root → This is the older common ancestor that all lineages share. The first one in the tree.
Two or more lineages are more related to each other if they share a recent common ancestor. This means that they all diverge from the same node.
Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.
There are also different phylogenetic relationships between lineages.
• Apomorphies → Occur when the involved lineages share a trait that they inherited from their most recent common ancestor. This trait evolved for the first time in this ancestor. → This relationship is a homology.
• Plesiomorphies → occur when the involved lineages share a trait inherited from a common ancestor, but that is older concerning the present traits exhibited by other descendants of the same common ancestor. → This relationship is a homology.
• Homoplasy → Lineages share a trait that evolved independently in each group. → This relationship is an analogy.
Look at the diagram below. It shows two solutions separated by a partially permeable membrane. Which number arrow shows the direction in which water molecules will move?
Answer:
Arrow no. 4
Explanation:
Water flows from a region of higher concentration to a region of lower concentration, i.e, osmosis.
Dilute solution means it has relatively less solute and more solvent, meaning more amount of water.
And just the opposite for concentrated solution.
So since the dilute solution has more water and concentrated solution has less, and water moves from a region of higher concentration to a region of lower concentration, option 4 is the correct answer.
During the osmosis process solvent is moved from a lower solute concentration to a higher solute concentration, hence arrow 4 defines the movement of water molecules.
What is osmosis?Osmosis is the process through which solvents move from a region of lower solute concentration to one of higher solute concentration across a semi-permeable membrane.
Water in the cell acts as a solvent and moves from lower solute concentration to higher solute concentration through a partially permeable membrane.
Conversely, in diffusion, molecules migrate from an area of greater concentration to regions of lower concentration without the need for a semi-permeable barrier.
Therefore diffusion of water molecules in the osmosis process from low solute concentration to high solute concentration, hence arrow 4 defines the movement of water molecules.

Mientras se calienta una solución en un vaso de precipitados, ¿cuál es el
equipo de seguridad apropiado para tener en el banco?
Answer:
Fire extinguisher.
Explanation:
Fire extinguisher is the appropriate safety equipment to have at the side of the baker while heating a solution in a beaker because sometimes the solution catch heat due to reactions with flammable liquids which leads to big incident so in this case fire extinguisher can avoid such type of incident by turn off the heat due to the gas present inside the container of fire extinguisher so this safety equipment is necessary at the side of the reaction.

Which viral reproduction cycle is used by long term viruses that hide in our body until triggered
Answer:
Lysogenic
Explanation:
There are two types of viral reproductive cycles, lytic and lysogenic. Let's look at both of them:
Lytic Cycle: Ex. of a lytic virus: Influenza (the flu)
A virus injects its genetic material into a cellProteins are created by the virus to hijack the host cell's DNA, allowing the virus control over the cellThe virus uses its control over the cell to make the cell create proteins for new viruses while it replicates viral DNAEventually, the host cell bursts (dies), and new viruses are releasedThose new viruses infect other cells; the cycle continuesHere we can see that the lytic cycle wastes no time. As soon as a cell is infected, it will immediately turn into a virus factory. Now, what about the lysogenic cycle?
Lysogenic Cycle: Ex. of a lysogenic virus: E. Coli
A virus injects its genetic material into a cellThe virus's DNA/RNA inserts itself into the host cell's DNA/RNAThe host cell continues to grow and reproduce. Whenever it produces new cells (by duplicating its genetic material and organelles then splitting in two), the virus's DNA/RNA will also be duplicated and exist in the new cell.The process continues, creating more and more cells with viral DNA/RNAA factor (it can be anything from radiation to nutrient levels) will eventually trigger all infected cells to undergo induction, which is a process very similar to the lytic cycleInduction will: cause the host cells to produce proteins for new viruses until the cell eventually bursts, leading to the release of the newly created viruses (much like the lytic cycle)Those new viruses infect other cells; the cycle continuesAn easy way to remember which is which is lyslowgenic. It's cheesy, but it works!
Please comment if you have any other questions! I've attached a picture for some reference on the cycles if you need it.

HELP PLEASE! Choose 3 of the water quality indicators write a summary of what it is
Answer:
Explanation:
Dissolved oxygen (DO)
The DO test measures the amount of oxygen dissolved in the water. Oxygen is essential for both plants and animals, but high levels in water can be harmful to fish and other aquatic organisms.
Water temperature
Aquatic organisms are dependent on certain temperature ranges for optimal health. Temperature affects many other parameters in water, including dissolved oxygen, types of plants and animals present and the susceptibility of organisms to parasites, pollution and disease.
pH
A pH test measures the alkalinity or acidity of water. A pH of 7 is neutral, below 7 is acidic and above 7 is basic or alkaline. Acid rain, from auto exhaust or other pollutants, causes a drop in the pH. Pollution from accidental spills, agricultural runoff and sewer overflows can also change the pH.
Escherichia coli (E. coli)
E. coli is a fecal coliform bacteria that comes from human and animal waste. The Environmental Protection Agency uses E. coli measurements to determine whether fresh water is safe for recreation. Disease-causing bacteria, viruses and protozoans may be present in water that has elevated levels of E. coli. Levels of E. coli can increase during flooding. E. coli is measured in number of colony forming units. The EPA water quality standard for E. coli bacteria is 394 colony forming units per 100 mL.
Mad cow disease is caused by deformed proteins called prions. The disease is spread when meat from an infected cow is eaten. Prions can make normal proteins deform into more prions. After a few years, the brain of an infected person or cow looks like a sponge full of holes. Are prions considered organisms?
Answer:
No.
Explanation:
No, prions are not considered organisms because they are proteins that the infection to the surrounding cells and tissue. Prion is a type of protein that can change normal proteins in the brain into abnormal. Prion diseases can affect both humans and animals and spread to humans by eating infected meat products. So we can conclude that prions are not organisms, they are proteins.
