Answer:
Cells have many structures inside of them called organelles. These organelles are like the organs in a human and they help the cell stay alive. Each organelle has it's own specific function to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA.

Villi in small intestine helps to increase area of absorption for minerals and nutrients.
True
False
Answer:true
Explanation:The function of the plicae circulares, the villi, and the microvilli is to increase the amount of surface area available for the absorption of nutrients. Each villus transports nutrients to a network of capillaries and fine lymphatic vessels called lacteals close to its surface.
How might a plant cell compensate for the excessive membrane fluidity that occurs during prolonged exposures to elevated temperature?A) Reduce membrane cholesterol content.B) Alter the lipid composition to have longer fatty acyl tails and fewer double bonds.C) Alter the lipid composition to have shorter fatty acyl tails and more double bonds.D) Alter the lipid composition to have shorter and more unsaturated fatty acyl tails.E) Reduce cholesterol content and alter the lipid composition to have shorter fatty acyl tails.
Answer:
E) Reduce cholesterol content and alter the lipid composition to have shorter fatty acyl tails.
Explanation:
Reducing the amount of fat makes the tissues or membranes have less plasticity, since these fatty acids with high temperatures increase their fluidity, are less dense and give greater plasticity in their elastic modulus.

What values or parameters can you adjust in this computer model?
Hi, you've asked an incomplete question. However, I provided some information about what a computer model does.
Explanation:
Remember, a computer model in simple terms is a representation of a real-life process or system using a computer. In other words, the computer model is a virtual representation of reality.
For example, weather forecasters often make use of computer models in other to predict changes in weather by taking note of certain values or parameters.
Answer:
You can adjust the type of fluid used, the amount of the fluid, and the amount of water.

Why might there be more dissolved oxygen in a lake in Vermont than in a similar sized lake in Florida in summer? (20 points)
A.) The sandy bottoms of Florida lakes absorb dissolved oxygen better than the rocks in Vermont.
B.) The cooler water in a Vermont lake would be able to hold more dissolved oxygen.
C.) Water evaporates more slowly from Vermont lakes, leaving more dissolved oxygen in them.
D.) More rain falls in Florida in summer, diluting the dissolved oxygen in the lake.
Answer:
B
Explanation:
In summer, the temperature of Vermont is lower than that in Florida. When temperature increases, the ability will decrease. So there is more dissolved oxygen in Vermont's lake.
Answer:
B.) The cooler water in a Vermont lake would be able to hold more dissolved oxygen.

One goal of scientists is to assign every organism a universally accepted name according to the system known as
Answer:
Binomial Nomenclature
Explanation:
Karl Line is the creator of the binomial nomenclature, which leads to uniqueness in naming plants and categorizing plants into classes, orders, genders, and species.
Binomial nomenclature in biology denotes the official method of naming species. As the word itself suggests, the scientific name is formed by a combination of two expressions: the name of a genus and a species.

Answer:
endoplasmic reticulum (ER)
Explanation:
What is the natural tendency of molecules to spread from an area of high concentration to an area of low concentration?
A.
Active transport
B.
Vesicle
C.
Passive transport
D.
Diffusion
Answer:
This concept is known as diffusion. Diffusion is a passive process, as it requires no energy for it to occur. In a cell, it is used as a method of passive transport since it requires no energy.
Explanation:

What was the result of using drainage blocks to keep water in the field level during the growing season?
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, it should be noted that the idea of blocking the drainage, which could cause waterlogging (since the water will not be able to leave the field), is a type of irrigation that ensures there is sufficient amount of water for the plants to grow during a growing season. Although, some plants do not grow well in environments like this (in the case of waterlogging) because this environment lowers oxygen level in the root o the plant (caused by the water at the top of the soil).
Why does the cell sometimes have to expend energy to move individual molecules across the cell membrane?
Answer:
Normally, molecules move naturally down a concentration gradient [From an area of high concentration to an area of low concentration] by a process called diffusion. However, sometimes the concentration of the needed substance is higher in the cell than out of it, so the cell uses a different process called Active Transport. Unlike Diffusion, Active transport requires energy, as it is going against a concentration gradient.
Cells expend energy to move cells across the cell membrane as they use Active transport rather than diffusion.
Human protein X is encoded by human gene X. Gene X consists of 4 exons of 200 bp each, interspersed with introns of 1,000 bp each.
An mRNA cap will be found on ____________.
a. the primary transcript
b. the mRNA
c. at least one of the lariats
d. the poly(A) tail.
e. exon 1
f. all exons
g. some introns
Answer:
a. the primary transcript
Explanation:
The first step in RNAm maturation is the modification of the 5' end of the transcript via the addition of a structure called a cap or 7-methyl guanosine cap. The enzymes responsible for the formation of this cap are recruited to the phosphorylated C-terminal domain after the addition of the first twenty to thirty nucleotides of ARN. The formation of the cap is started by the addition of a GTP molecule oriented inversely to the 5' end nucleotide on RNA. Then methyl groups are added to this G residue and to the ribose forms of one or two nucleotides located on the 5' end. All these reactions take place in the nucleus when the mRNA is found as a primary transcript.

Relative dating techniques have been around for hundreds of years. How did newer
absolute dating techniques change the way we look at seologic cross section
It allowed us to put reologie cross sections lo better order
It allowed us to put a formation date on some geologic crosections
It allowed us to disprove the existence of land bridges
It allowed us to start using the idea of superposition
Answer:
It allowed us to put a formation date on some geologic crossections
Explanation:
Absolute dating is a newer way of evaluating the chronology of historical events by assigning numerical ages to them. The age thus assigned might not be the exact age but it is still closer to the real age.
It is unlike relative dating techniques which simply give the chronology or order of past events instead of the exact dates. Relative dating techniques have been in use before the emergence of absolute dating techniques in the twentieth century.

the zipper like mountain ranges the run across the flor of the ocean are called ??
Answer:
answer is mid ocean ridges
Answer:
Undersea mountain ranges are mountain ranges that are mostly or entirely underwater, and specifically under the surface of an ocean. If originated from current tectonic forces, they are often referred to as a mid-ocean ridge. In contrast, if formed by past above-water volcanism, they are known as a seamount chain

Sucrase is the enzyme that catalyzes the reaction
Sucrose
Sucrose + Water ----------------------> Glucose + Fructose
If we place 5 moles of Sucrase (enzyme) and 5 moles of Sucrose in a solution of water, how many moles of each substance would we have after 10 minutes?
Answer:
0 moles of sucrose
5 moles of sucrase
5 moles of glucose
5 moles of fructose
Explanation:
Sucrase hydrolyses the glyosidic bond in a sucrose molecule to produce one glucose and one fructose, therefore;
Assuming all the sucrose has been hydrolysed in 10 minutes, you would have:
0 moles of sucrose
5 moles of sucrase
5 moles of glucose
5 moles of fructose
Describe limits to cell division.
Answer:
All cells in the body have this internal control and most cells only divide between 50-70 times before they stop or die.
The study of cells is called cell biology.
The cell theory is given by Rudolf Virchow
The postulates of a cell theory are as follows:-
All the organism is made up of cellThe structure and the functional unit of life is the cell.All the pre-existing cell is made up of old cell.The limits of the cell division are cancer cells. The cancer cell does not stop after a limit. It divides continuously and forms a tumor.
Hence, the correct answer is a cancer cell.
