movement of a solvent (such as water) through a semipermeable membrane (as of a living cell) into a solution of higher solute concentration that tends to equalize the concentrations of solute on the two sides of the membrane.
How would the absence of juxtamedullary nephrons affect the volume of urine and its osmotic concentration?
Answer:
Increase volume; decrease osmotic concentration
Explanation:
Nephron is the functional unit of a kidney.
The juxtamedullary nephrons is responsible for the development of the osmotic gradients. The osmotic gradient helps in ensuring the urine is well concentrated and helps in adequate water reabsorption.
The absence of juxtamedullary nephrons affect the volume of urine and its osmotic concentration by Increasing the volume and decreasing the osmotic concentration.
Which gas is responsible for global warming and Which gas is responsible for ozone layer depletion?
Answer:
Green house gases like carbon dioxide, carbon monoxide, carbon tetra chloride, methane, sulphur dioxide, nitrogen dioxide, etc .. are responsible for Global warming and Chlorofluorocarbons and nitrides of oxygen are responsible for Ozone layer depletion.
Explanation:
One of the first things the IPCC concluded is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, buildings, factories, and power plants. The gas responsible for the most warming is carbon dioxide, or CO2.
Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion. The total amount of effective halogens (chlorine and bromine) in the stratosphere can be calculated and are known as the equivalent effective stratospheric chlorine (EESC).

Explanation:
In addition to the repair of DNA double-strand breaks, homologous recombination is a mechanism for generating genetic diversity by swapping segments of parental chromosomes. During which process does swapping occur?
Answer:
during cell division (meiosis)
Explanation:
During meiosis, DNA double-strand breaks (DSBs) between homologous chromosomes are induced and, after the exchange of DNA pieces, breaks are jointed by specific DNA-repair enzymes (such as DNA glycosylases). DSBs can be repaired by two different mechanisms: non-homologous end-joining (NHEJ) and homologous recombination (HR), which have different functional consequences. These mechanisms of recombination have potential for increasing the genetic variation since the resulting gametes will contain a different set of chromosome fragments.
For the following biomolecular interactions, choose the main weak force interactions that mediates them.
Interaction between hydrophobic (nonpolar) amino acid side chains van der Waals interaction
Repulsion between negatively charged backbone of DNA double helix van der Waals interaction
Interaction between water and carbonyl oxygen of guanine hydrogen bond
Answer:
Interaction between hydrophobic (nonpolar) amino acid side chains is due to hydrophobic interactions.
Repulsion between negatively charged backbone of DNA double helix is due to electrostatic repulsion forces.
Interaction between water and carbonyl oxygen of guanine is due hydrogen bonding
Explanation:
The hydrophobic effect refers to the tendency of non-polar substances forms aggregates in an aqueous solutions in order to avoid interactions with water molecules. This results in a favorable entropy increase.
For non-polar amino acids, hydrophobic interactions are important in stabilizing their structure wherein they are densely packed within the core of a protein while those with with polar groups are found in the exterior.
The phosphate backbone of DNA is negatively charged. Since like charges repel, therefore, electrostatic repulsion forces of the ions are responsible the repulsion of the backbone DNA double helix.
Hydrogen bonds are formed between electronegative oxygen atoms and hydrogen atoms of neighboring molecules due to the partial negative and positive charges on each of the atoms.
This hydrogen bonding is responsible for the interaction between water and carbonyl oxygen of guanine as the hydrogen atoms of the water molecules are attracted to the oxygen atoms of the guanine molecules due to the partial charges on each of the atoms.

what are the disc shaped membranous structures inside of the chloroplast where the light-dependent reactions take place
Answer:
These are the thylakoids
Explanation:
The thylakoids which contains the chlorophyll is the primary site of photosynthesis. It is covered by layers of cell called the thylakoid membrane.These are the actual site for light dependent reaction.This membrane contains both photosytem I and ii, ATPase enzymes, and Cytochrome b6f complex.While the photosystem i and ii transfer elecrons during photosynthesis, the ATPase enzyme control the catalysis the phosphorylation of ADP to ATP needed for the light independent stage, the Cytochrome proteins acts as the ETC. involved in the transfer of electron during light dependent stage.
When thylakoids are packed together in disc shape they are refer to as Grana,(singular -granum).Each grana are linked together by intergrana.Thus two or more grana are linked by intragrana to form a single photosynthetic functioning unit.The entire structure is bath continuously by the fluid medium-Stroma.
Their stacked and disc shape is to increase the surface area available to accommodate enough ETC, needed to transport electron for chemiosmosis needed for photosynthesis.
How was cell discovered?
Answer:
The cell was first discovered and named by Robert Hooke in 1665. He remarked that it looked strangely similar to cellula or small rooms which monks inhabited, thus deriving the name. However what Hooke actually saw was the dead cell walls of plant cells (cork) as it appeared under the microscope.
Describe the Nebular Hypothesis Theory
Explanation:
The solar nebular hypothesis describes the formation of our solar system from a nebula cloud made from a collection of dust and gas. The nebular hypothesis is the idea that a spinning cloud of dust made of mostly light elements, called a nebula, flattened into a protoplanetary disk, and became a solar system consisting of a star with orbiting planetsWhich of the following statements about translational termination is correct?A. Accessory proteins called elongation factors recognize the stop codon in the mRNA to terminate translation.
B. The ribosome keeps translating until it reaches the end of the mRNA and falls off the transcript.
C. Peptidyl transferase breaks the bond between the growing polypeptide chain and the tRNA in the P site, but there is no new charged tRNA in the A site, which results in the termination of translation and release of the polypeptide.
D. A special stop-tRNA enters the A site and terminates translation.
E. Rho proteins bind to the mRNA when the ribosome pauses and stops translation.
Answer:
C
Explanation:
The correct answer here would be that the peptidyl transferase breaks the bond between the growing polypeptide chain and the tRNA in the P site, but there is no new charged tRNA in the A site, which results in the termination of translation and release of the polypeptide.
The translation process stops when the stop codon in the mRNA being translated enters site A in the translation complex. When this happens, the release factor recognizes the stop codon and makes the enzymes that form peptide bonds to add water to the last amino acid on the chain.
The addition of water leads to the breaking of the peptide bond by peptidyl transferase, causing the separation of the polypeptide chain from the tRNA and the eventual release of the protein.
Hence, the correct option would be C.

5,890,000,000,000 (The distance to the sun in km)
pls help.
Answer:
[tex]D=5.89\times 10^{12}\ km[/tex]
Explanation:
The distance to the Sun is 5,890,000,000,000. We need to write this distance in km.
A number can be written as [tex]x.0\times 10^y[/tex] in scientific notation where x is a real no and y is any integer.
There are 10 zeros in the given number and also there are 12 digits after. It would mean that,
[tex]D=5.89\times 10^{12}\ km[/tex]
So, the distance in scientific notation is : [tex]D=5.89\times 10^{12}\ km[/tex]

charles darwin is credited with outlining the principles of evolution by natural selection. what aspects of the scientific method can be identified in darwin's work
Answer:
Charles Darwin's work followed the rules of hypotheses creation and testing.
In order to prove a scientific suspicion, a true scientist has to follow the above methods.
So Darwin probably theorized that the offspring of certain living entities were by either environmental conditioning or by natural selection different genetically from their parent.
He tried this hypothesis over time and using the results he got, modified his theory.
