Answer:
The first statement is true, while the second statement is false.
Explanation:
Every living organism needs a particular amount of food in order to be able to survive. Each species though has its own different requirements, and there are great variations that occur because of size, lifestyle, is the organism cold-blooded or warm-blooded, etc.
In this case, we have to examples. In the first one, a single mouse needs 4 square meters of grass in order to stay healthy. In order to get the amount of grass needed for fifty mice, we just need to multiply the number of mice by the amount of grass needed for one of them:
50 x 4 = 200
We got 200, meaning that 200 square meters of grass will support a population of 50 mice.
In the other case, a single snake needs 10 mice in order to stay healthy. To get a result how many mice are needed for 10 snakes, again we just need to multiply the number of snakes by the number of mice a single snake needs:
10 x 10 = 100
We got 100, meaning that 10 snakes need 100 mice in order to stay healthy.

a. Shelter
b. Income
c. Feltilizers
d. Windbreakers
Answer:
Windbreakers
Explanation:
Income and fertilizers have nothing to do with it, so those are not it. Then there are shelter and windbreakers. It kind of acts as a shelter, but mainly it protects crops and homes by acting as a windbreaker. If it was shelter, that would mean that the crops would mainly be planted under the trees to reduce damage from storms and typhoons. Therefore, it is D) Windbreakers.

An animal leaves its footprint in wet mud, and later, when the mud dries, the footprint can be filled with plaster. When the plaster hardens, it has
same shape as the foot of the animal. The plaster cast could then be used to make new footprints in soft mud identical to those made by the animal. The
process of using the plaster cast to make new footprints most accurately models
translation of mRNA codons to form a protein.
transcription of mRNA from the original DNA code.
insertion of nucleotides into the mRNA codons
deletion of nucleotides from the tRNA anticodons.
Answer:
The process of using the plaster cast to make new footprints most accurately models transcription of mRNA from the original DNA code
Explanation:
Transcription is a process in protein synthesis that takes place in the nucleus. During transcription, the DNA of a gene is used as a template to make an RNA molecule. In the process, nucleotide bases which are complementary to those found in the DNA molecule pairs with the DNA bases in a process called complementary base-pairing. However, Uracil is the nucleotide base that binds to adenine in the mRNA instead of thymine. An enzyme called RNA polymerase II catalyzes the formation of a mRNA molecule. Three steps are involved in transcription:
Initiation- is the beginning of the transcription process when RNA polymerase binds to DNA.
Elongation- addition of nucleotides to the RNA strand.
Termination- is the end of the process whereby RNA strand detaches from DNA template. The resulting mRNA is a single-stranded copy of the gene.
It models the transcription of mRNA from the original DNA code.
The process of using the plaster cast to make new footprints most accurately models the transcription of mRNA from the original DNA code because both have exactly the same type of materials.
Transcription is the process in which the information present in a strand of DNA is copied into a new molecule of messenger RNA which serve as a blueprints for protein synthesis during the process of translation. The mRNA has all the information that is present in the original DNA so we can conclude that it models the transcription of mRNA from the original DNA code.

Describe the movement of oxygen molecules if there were more oxygen molecules
outside the cell
Explanation:
Because there's a higher concentration of oxygen molecules outside the cell compared to the cell's cytoplasm, you'll see that oxygen diffuses into the cell along this concentration gradient. ... Because the molecules are moving at random, some will move out of the cell, but most will be moving in in this case.
Transporation is the mechanism by which the molecules and enzymes move in and out of the cell. When more oxygen is present outside the cell diffusion will occur along the concentration gradient.
What is diffusion?Diffusion is a transportation mechanism that involves the movement of the ions and the molecules from the high concentration area towards the low concentration region.
The high amount of oxygen present outside the cell will diffuse through the cell membrane inside the cell along the concentration gradient so that the concentration inside and the outside achieves equilibrium.
Therefore, the movement of the oxygen molecules from high concentration to low is diffusion.

The glucose transporter used by cells to obtain glucose from the media is a protein embedded in the membrane. When researchers first started to investigate the glucose transporter's structure they had trouble because it seemed to have 2 differnet shapes! Eventually they realized that the glucose transporter changes shape as it moves glucose into the cell but does not require energy to do it's work. Which of the following is the best description for the glucose transporter?
a. It's a carrier protein doing facillitated diffusion
b. It's a carrier protein doing active transport
c. It's a protein channel doing facillitated diffusion
d. It's a protein channel doing active transport
Answer:
a. It's a carrier protein doing facillitated diffusion
Explanation:
Facilitated diffusion may be defined as the transportation of molecules from a high concentration to a low concentration that is down the concentration gradient without input of the energy. Whereas the active transport is transportation of the molecules from the low concentration to the high concentration which is against concentration gradient by the membrane protein.
The glucose transportation process requires membrane protein for the transport and does not require any energy. Therefore, it is carrier protein which is doing the facilitated diffusion.

Unstained cells have very little contrast. What single adjustment could you make to your microscope that would make cells easier to see at the same time while reducing the evaporation of your sample?
Answer and Explanation:
Microscope objects have thermal profiles. These profiles differ as a purpose of their physical parameters. Most objects are sold and designed for the resolution of fixed cell microscopy.
There is little indication that the temperature cycle affects the strain characteristics. A large box can be constructed around the microscope and heated with hot air.
The heating system's cycling causes the specimen to drift out of focus and can also change the coverslip position.
The microscope can be equilibrated to a single temperature to eliminate the movement resulting from the thermal expansion of the microscope's components.
Air currents connecting the specimen chamber should also be reduced—tight control of temperature for the entire laboratory and microscope. Any change in the temperature can lead to unwanted movement in the microscope. Heating ducts often produce localized temperature changes.
