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.
What is a hydrophobic molecule?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:
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 study of evolutionary relationships that includes a branching pattern showing lineages diverging is called... * 1 point
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.
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.
Owls can be found all over the world, EXCEPT ________. *
Answer:
Owls can be found in all parts of the world except Antarctica.
Explanation:
Owls are found in many different habitats, such as deserts, forests, prairies, and even the Arctic tundra. They nest in trees, in holes in the ground, in barns, and in caves. And while many other birds migrate to warmer places during the winter, most owls do not. They live in the same place all year round. Antarctica is the only place in the world without owls because of the extreme temperatures of the ice desert, making it insanely hard for much life to exist there.

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.
How could the aquifer around the Los Angeles are in California be susceptible to an impact by a Tragedy of the Commons?
Answer:
Due to over-pumping of water.
Explanation:
The aquifer around the Los Angeles are in California could be susceptible to an impact by a Tragedy of the Commons because the people used more water than the aquifer receives. The excess use of water from the aquifer through the well causes depletion of water which results in the shortage of water to fulfill the needs of existing population so it is wise to use water efficiently and used lower or equal water the aquifer receives in order to maintain level of aquifer.

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.

What is the ultimate role of ecological succession in an environment
Answer:
The stable, end stage of ecological succession in which the plants and animals of a community use resources efficiently and balance is maintained by disturbances such as fire. The ultimate goal of ecological succession. After a natural disaster and continues until a climax community is reached.
Explanation:
The ultimate role of ecological succession in an environment is to reach the equilibrium in an ecosystem.
What is Ecological Succession?This event involve in the steady and gradual change in a species of a given area with respect to the changing environment is called as ecological succession.
The changes are inevitable process where all biotic components of the ecosystem keep up with the changes in our environment.
This process ultimately reach equilibrium in the ecosystem and the community that achieves this referred as a climax community, where some species increase in number and others decrease.
The communities that undergo changes sequentially in an area is called sere, so it is also called as seral stage or seral community.
Evolution has taken place simultaneously with that of ecological succession, so all the communities we observe are the result of ecological succession.
