In a popular movie, a salt water fish jumped into a freshwater drain to be reunited with his father.
Using your knowledge of osmosis and solutions what would have really happened to the cells in the
fish?
А
The cells would have expanded and burst because of water entering the cells.
B
The cells would have shrunk as water left the cells.
с C
The cells would have remained the same as the freshwater is isotonic.
D
The cells would have become freshwater cells until reaching the ocean.
Answer:
A
Explanation:
fresh water is hypotonic to the fish cell,that means water will diffuse into fish cells by osmosis because a hypotonic solution contains low solute concentration.

3. How does oxygen cross into the cell?
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.
The oxygen cross into the cell as water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion has been one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.
What is osmosis?
Osmosis has been the process in which molecules of the solvent pass via a semipermeable membrane from a lower concentrations to higher concentration or from less concentrated solution to high concentrated solution. In the process of the osmosis movement of the water takes place.
There are mainly three types of the osmosis and these are hypertonic, hypotonic, and isotonic. The process of osmosis has been passive transport as water moves from low solute concentration to high solute concentration.
Osmosis has been also known as diffusion of water or solvent via a membrane which allows only selective substance to go across the channel. The process of osmosis does not require ATP because it is a passive process.
Therefore, The oxygen cross into the cell as water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ).

Which is the role of restriction enzymes?
to isolate the selected gene
to cut DNA into fragments of different lengths
to move and separate the strands of DNA
to join the sticky ends of DNA fragments
Answer:
to cut DNA into fragments of different lengths
Explanation:
A restriction enzyme is a protein that recognizes a specific, short nucleotide sequence and cuts the DNA only at that specific site, which is known as restriction site or target sequence.
More than 400 restriction enzymes have been isolated from the bacteria that manufacture them. In live bacteria, restriction enzymes function to defend the cell against invading viral bacteriophages. Restrictions sites in the viral genome (a "happy accident" of nature, as far as the bacteria are concerned, since they don't appear to have any specific function in the virus) are cleaved by the bacterium's restriction enzymes, fragmenting and destroying the DNA of invading bacteriophages before it can incorporate into the host's genome and take over the cell.
A bacterium is immune to its own restriction enzymes, even if it has the target sequences ordinarily targeted by them. This is because the bacterial restriction sites are highly methylated, making them unrecognizable to the restriction enzyme.
Isn't evolution fantastic?
The correct answer is option C i.e. to cut DNA into fragments of different lengths.
what is restriction enzyme?A restriction enzyme is a bacterial protein that cleaves DNA sequences at sequence-specific places, resulting in DNA fragments with known sequences on both ends.
Certain laboratory processes, such as recombinant DNA technology and genetic engineering, require the use of restriction enzymes.
There are four different types of restriction enzymes: type I, II, III, and IV, which differ principally in structure, cleavage site, specificity, and cofactors.
Both restriction and methylase functions are carried out by a single big enzyme complex in Types I and III enzymes.
The restriction enzyme is independent of its methylase in the Type II system.
Several thousand type II restriction enzymes have been identified from a variety of bacterial species.
These enzymes recognize a few hundred distinct sequences, generally four to eight bases in length.
Type III restriction enzymes are a group of endonucleases that recognize a non-pallindromic sequence, comprising two inversely oriented sites.
Type IV restriction enzymes cleave only methylated DNA and show weak sequence specificity.
hence, the correct answer is option B.

A radioactive substance has a half-life of 1.25 million years. What is the age of a rock in which 6.25% of the original radioactive atoms remain? 5 million years old 6.25 million years old 3.75 million years old6 2.5 million years old 1.25 million years old 625 thousand years old
Answer:
The age of the rock is 5 million years
Explanation:
Fraction of radioactive substance remaining = 6.25% = 625/10000 = 1/16
Number of half-lives undergone by the substance to leave behind 1/16 of the original sample
1/16 = (1/2) * (1/2) * (1/2) *(1/2)
Therefore, the substance have decayed 4 times
One half=life = 1.25 million years
Four half-lives = 4 * 1.25 million years = 5 million years
Therefore, the age of the rock is 5 million years

Answer: The options are not given, here are the options.
a. located in the space outside the nucleus.
b. spread evenly throughout an atom. c. concentrated at multiple sites in an atom.
d. concentrated in the center of an atom.
The correct option is D.
concentrated in the center of an atom.
Explanation:
In an atomic model, the atomic particles has the nucleus which is located at the center of the particle. This nucleus contain positive charge which is called proton at the center and the neutrons(no charge). The electrons is located out side the particle she'll or nucleus and atomic particles become neutral because the number of protons is equal to the number of electrons which is negatively charge orbiting outside the nucleus.

Answer:
it would be (d) amount of pressure in the air caused by gravity and matter moving on all objects
Explanation:
d. amount of pressure in the air caused by gravity and matter moving on all objects.
Air pressure:The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. As the pressure decreases, the amount of oxygen available to breathe also decreases. Atmospheric pressure is an indicator of weather.Thus, the correct statement that describes air pressure is the amount of pressure in the air caused by gravity and matter moving on all objects i.e. option d.

Explanation:
After the 2004 tsunami disaster in Asia, there were reports that trained elephants had moved away
from the coastline before the tsunami struck. Scientists wondered if elephants had sensed the oncoming wave and the earthquake that created it. Elephant trunks have two kinds of nerve endings that are sensitive to pressure differences, but little is known about nerve ending distribution in the elephant's skin or feet. An elephant has recently died at a nearby zoo and scientists have decided
to dissect one of its feet to search for any special nerve endings. Results show a high density of pressure-sensitive nerve endings in the front of the foot and along the edges, which supports the
idea that elephants are sensing seismic signals produced by such disasters as earthquakes.
1. Independent variable
2. Dependent variable
4. Constant
5.controls
6.hypothesis
7. Sample size
8. Presence of repeated measures
Answer:
In the given dissection for the finding of the idea that elephant can sense the seismic signals generated by natural disasters are as follows:
Independent variable: it is the variable which influences the dependent variable or the dependent variable depends on. Here the area of the feet that is chosen to be dissected is the independent variable.
Dependent variable: It is the variable that is manipulated or influenced by the independent variable, in this dissection the sensitive to the pressure, nerve ending in the selected area of the feet.
Constants: It is a variable that remains constant or fixed in the complete experiment. The number of the selection area is constant hat is in one foot here.
Controls: There is no such control present in this experiment However, the density of pressure-sensitive nerve endings can be considered as control.
Hypothesis: the pressure-sensitive ending is significantly enriched in the feet of the elephant.
Sample size: subject in this study is only one elephant and one foot so the sample size is 1.
Presence of repeated measures: Repeated measures are not performed during this study is only one experiment of dissection is performed on a single subject.
