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.
I am a microorganism that helps to increase soil fertility naturally.
Ribosomes
Rhizobium
Leguminous plants
Answer: rhizobium
Explanation: Some bacteria like rhizobium and blue green algae are able to fix nitrogen gas from the atmosphere to enrich the soil with nitrogen compounds and increase its fertility.
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.
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

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).
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.
Which statement describes competition in an environment? Organisms share a place to sleep. A living thing consumes berries on a tree. Sunlight shines only three months out of the year. A stream supplies an abundance of water in a forest.
Answer:
Sunlight shines only three months out of the year.
Explanation:
I think this is right
Because abundance means a large amount so there would be no competition there.
If organisms share a place to sleep then that means no competition
If a living thing is consuming berries on a tree then the living thing is just eating
But if the sunlight only shines three months out of the year then that can cause a shortage of food in the environment causing for the living creatures in the environment to compete for the food that is left since there won't be enough to supply for and abundance of living things.
The statement that describes competition in an environment is option B a living thing consumes berries on a tree. Thus, consuming berries on a tree is reducing the availability of the food for other livings depends on the berries.
What is survival of living things?In the nature, the concept that survival of the fittest domintates. The organisms which are fit physically and are smart to gather food will survive in the nature otherwise they will extincts.
An ecological community is a collection of populations of at least two distinct species that interact both directly and indirectly in a specific geographic area. Within this community, diffrent organisms can be found .
Numerous ecological characteristics and functions, including nutrient cycling and food webs, are based on interactions between species. Depending on the evolutionary context and environmental factors that they take place in, these interactions can have a variety of different natures.
Because of this, ecological interactions between particular individuals and entire species are frequently difficult to identify and quantify and depend on their scale and context they face extinction. Hence, option B is correct.

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.

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.
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.

How are cancerous cells different from normal cells?
Answer:
Cancer cells differ from normal cells in many ways that allow them to grow out of control and become invasive. One important difference is that cancer cells are less specialized than normal cells. That is, whereas normal cells mature into very distinct cell types with specific functions, cancer cells do not.
