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.

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.

The stages of human gestation and their time duration are given below:

Fertilization may be defined as a biological event that occurs by the fusion of male and female gametes successfully to produce a zygote.

The embryo develops after four to five weeks of conception which is the first trimester, organs initiate to develop by the end of the first trimester.

Swallowing is initiated at the beginning of the second trimester, and all organs are completely developed by the initiation of the third trimester. While all senses of hearing and seeing are developed by the middle of the third trimester.

Therefore, each trimester is characterized with its own functionality.

Answer:

Salts, proteins and hormones.

Explanation:

Salts, proteins and hormones are the substances that are present in red blood cells.  Plasma of the blood is composed of 90% water, salts, lipids and hormones. It is also rich in proteins such as albumin, immunoglobulins, clotting factors and fibrinogen. These substances are important parts of blood which made the blood to perform its function to transport nutrients in the body so after the removal of water, Salts, proteins and hormones are present in the red blood cell.

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.

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.

The membrane is basically semi-permeable, which means that some molecules can pass through but others cannot. Small hydrophobic molecules and gases, such as oxygen and carbon dioxide, rapidly cross membranes.

The term "hydrophobic" literally means "fear of water." Water is repelled by hydrophobic molecules and surfaces.

Oil and other hydrophobic liquids will separate from water. Hydrophobic molecules are typically nonpolar, which means that the atoms that comprise the molecule do not generate a static electric field.

Hydrophilic molecules are the ones that are usually attracted to water and basically dissolve well in polar solvents.

Small hydrophobic molecules and gases, such as oxygen and carbon dioxide, cross membranes very quickly.

Because small nonpolar molecules like oxygen and carbon dioxide are soluble in the lipid bilayer, they can easily cross cell membranes.

Small uncharged polar molecules like water can pass through membranes, but larger uncharged polar molecules like glucose cannot.

Thus, these molecules can be easily passed through the plasma membrane.

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)

Here 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

An 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.

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.
