What makes a membrane semipermeable?
Explanation:
Membranes
Recall that phospholipids have a hydrophobic end and a hydrophilic end and that when placed in water they will orient themselves accordingly (5.11 pg 79). This is the basis for the plasma membrane of a cell. The cell membrane consists of a phospholipid bilayer with embedded proteins. We refer to the modern conceptual model of the cell membrane as the "fluid mosaic" model since the phospholipids are able to move about across the surface of the membrane (fluid) and the proteins are many and varied (mosaic) (5.12).
Attached to the some proteins and to some of the phospholipids are oligosaccharides (short polysaccharides). When a protein has an oligosaccharide attached it is called a glycoprotein. Glycolipids are phospholipids with the sugar chains added. These oligosaccharides are found on the outside of the membrane and are used in cell to cell recognition. They differ among species, among individuals and within individuals.
Membrane proteins can have a number of functions, such as transport proteins, enzymes (more on these shortly), receptor sites, cell adhesion, attachment to the cytoskeleton. (5.13)
The most important thing about membranes is that they regulate what moves in and out of a cell. The membrane is selectively permeable because substances do not cross it indiscriminately.
Some molecules, such as hydrocarbons and oxygen can cross the membrane. Many large molecules (such as glucose and other sugars) cannot. Water can pass through between the lipids. Ions such as H+ or Na+ cannot.
Transport proteins make passage possible for molecules and ions that would not be able to pass through a plain phospholipid bilayer. Some transport proteins have a hydrophilic tunnel through them which allows polar molecule or ions to pass. Others actually bind to the molecules and move them across the membrane. In either case transport proteins are very specific.

A. All objects in space move around Earth in perfect circles.
B. All objects in space move around the sun.
C. All objects in space move in parallel tracks.
D. All objects in space are perfect spheres.
Answer:

What is an energy pyramid????
Answer:
From each trophic stage in an ecosystem, a pyramid of energy reflects how much energy, originally from the sun, is retained or deposited in the form of new biomass. Around 10% of the energy is typically passed from one trophic level to the next, preventing a large number of trophic levels from forming.

In order to identify genes that function together in genetic pathways researchers can perform modifier screens, looking for second site enhancers or suppressors of a mutant. Which of the following is the most reasonable strategy for carrying out a suppressor screen in particular?
a. analyze the DNA sequence near the mutation of interest, looking for sequences that may act as silencers.
b. identify mutations that, when crossed with the original mutant, result in synthetic lethality.
c. mutagenize the original mutant and look for new mutations that reduce the severity of the original mutant phenotype.
d. screen for enhancer-trap strains that show gene expression differences in the original mutant.
e. isolate mutants with phenotypes similar to the original mutant phenotype and then cross the mutants to identify the affected genes.
Answer:
c. mutagenize the original mutant and look for new mutations that reduce the severity of the original mutant phenotype.
Explanation:
A suppressor screen is a technique employed to identify a second mutation (i.e., a suppressor mutation) capable of reverting/alleviating the phenotypic effects associated with an initial mutation. There are two types of mutants obtained from this approach: 1-Intragenic suppressors, which involve second mutations inside the gene that restore the original function of the mutated gene; and 2- Intergenic suppressors, also known as extragenic suppressors, which involve second mutations in a gene that is distinct from the original mutated gene (usually extragenic suppressors function in the same signaling pathway as the original mutated gene).

Let the retention factor of species A be 0.5, while the retention factor of species B be 0.3. If species A moves 1.0 cm how far does species B move
Answer:
The correct answer is - 1.2 cm.
Explanation:
The retention factor is represented by Rf.
Given:
Rf of species A is = 0.5
Rf of species B is = 0.6
Formula:
Rf = distance the compound moves/distance the solvent moves
Rf(A)/Rf(B) = [tex]\frac{distance moved by A/distance moved by solvent}{distance moved by B/distance moved by solvent}[/tex]
Rf(A)/Rf(B) = distance moved by A/distance moved by B
0.5/0.6 = 1/distance moved by B
distance moved by B = 0.5/0.6
= 1.2 cm
The distance traveled by species B if species A moves 1.0 cm is 0.6 cm
The Retention factor [tex]\mathbf{R_f}[/tex] is the ratio of the distance moved by the species by the distance moved by the solvent front.
From the information given:
[tex]\mathbf{R_f(A) = 0.5}[/tex][tex]\mathbf{R_f(B) = 0.3}[/tex]For specie A;
[tex]\mathbf{0.5 = \dfrac{1.0 \ cm}{distance \ moved \ by \ solvent \ front}}[/tex]
[tex]\mathbf{distance \ moved \ by \ solvent \ front= \dfrac{1.0 \ cm}{0.5}}[/tex]
distance moved by solvent front = 2 cm
For specie B;
The distance traveled by the species B will be:
= 0.3 × 2.0 cm
= 0.6 cm
