Answer:
The ribosome is a highly complex cellular machine. It is largely made up of specialized RNA known as ribosomal RNA (rRNA) as well as dozens of distinct proteins (the exact number varies slightly between species). The ribosomal proteins and rRNAs are arranged into two distinct ribosomal pieces of different size, known generally as the large and small subunit of the ribosome.

More than 90% of plants have mycorrhizal associations with fungi. How might this association have evolved (include mechanisms)
Answer:
It is a symbiotic relationship and it evolved because of the benefits both plants and fungi derive from the association.
Explanation:
Mycorrhizal association is a symbiotic association between fungi and plants where both of the benefits from the relationship. The fungi inhabit the root system of plants which increase the ability of the plant's root system to absorb water for it own use and the fungi benefited from it by carbohydrates from plants which is produced as a result of photosynthesis.

Which pair of factors affects the force of gravity between objects? direction and distance mass and distance mass and shape shape and time
Answer:
It's B
Explanation:
Mass and distance affects the force of gravity between objects.
Thus, option B is correct.
What is force of gravity?Force of gravity is defined as the force of attraction between any two objects in the universe.
The force of attraction depends upon the mass of the object and the square of the distance between them.
Mass is the total amount of matter contained by an object.More the matter of the object has, the more the mass.Weight of an object can be zero but mass of the object cannot be zero.
Distance is defined as the amount of space between two places or things. Measurement of distance are kilometer, inch, foot, yard.
Therefore,Mass and distance affects the force of gravity between objects.
Thus, option B is correct.

Identify the igneous rock
Answer: Red Volcanic Rock
Explanation: Extrusive igneous rocks, also known as volcanic rocks, are formed at the crust's surface as a result of the partial melting of rocks within the mantle and crust.
Describe where in nature you would see contaminated water actively weathering rocks and how it may differ from non-contaminated water.
Answer:
The contaminated water contains harmful chemicals which results in the cracking of rock.
For example: The feldspar crystals within the granite react with the water chemically to form clay minerals which makes the rock weak and hence result in weathering.

Maltase is an enzyme that catalyzes the hydrolysis of the disaccharide maltose. This process occurs during human digestion when maltase is secreted by the intestine and then converts maltose into glucose. Which two classes of biomolecules are directly involved in this process?
A .proteins and carbohydrates
B. lipids and proteins
C. carbohydrates and nucleic acids
D. carbohydrates and lipids
Answer: D
Explanation:
Carbohydrates and nucleic acids are the two main classes of biomolecules which are involved directly in the process of digestion of maltose through maltase enzyme. Thus, the correct option is D.
What is Maltase?Maltase is a an enzyme which belongs to the alpha-glucosidase enzyme family. These are found in the small intestine's brush bordered cells. The hydrolysis of the disaccharide maltose into two simple sugars such as glucose is catalyzed through the enzyme maltase.
Maltose is a disaccharide which is produced by the enzymatic hydrolysis of starch, which is a homopolysaccharide and this is catalyzed by the enzyme amylase. Maltose sugar is further hydrolyzed by the enzyme maltase to produce two molecules of d-glucose.
Therefore, the correct option is D.

Primer design is a critical step for the detection of a particular sequence in a sample. Which of the following would be true of primer design?
The group of choices is as follow:
A. RNA polymerase are added to the PCR mix to design random primers
B. If detecting viral infection by PCR, the primers must not be complimentary (match) to regions of human DNA
C. Pairs of primers must be designed, one to start amplification with Taq polymerase, the other to start amplification with human polymerase
D. Primers are optional if you want to amplify all DNA within a sample
Answer:
The correct answer is - B. If detecting viral infection by PCR, the primers must be complementary to regions of human DNA.
Explanation:
Short, single-stranded segments of DNA sequences utilize in the real-time PCR or polymerase chain reaction technique are called primers. Primers used to hybridize the region of the segment needed to be amplified.
The human polymerase enzyme is not used in the PCR reaction and requires a 3'OH group to synthesize the DNA by amplification which is possible only in the presence of primers as they have a 3'OH.
If, somehow, the number of daylight hours did not change throughout the year, but Earth
was still tilted at 23.5°, would there still be seasons in the Northern and Southern
Hemispheres of Earth? Would the temperature difference between the seasons still be as
great? Explain your reasoning.
Answer:
There would still be seasons, because the intensity of light would still change throughout the year, due to the earth's tilt.
Explanation:
If, somehow, the number of daylight hours did not change throughout the year, but Earth was still tilted at 23.5° then-
Yes, there would still be seasonsNo, the temperature difference between the seasons would not be as greatThe tilt of the Earth's axis at 23.5° leads to the different parts of the Earth to gets a high or less amount of direct sunlight at different times of the year.
If there would be no tilt of the earth then there would be no seasons on Earth.If the number of daylight hours did not change then seasons still be there due to the intensity of light would still change throughout the year as the earth is still tilted. If the number of daylight hours did not change throughout the year then the temperature difference would not be as great due to less light in the daytime will not be able to heat enough and the Earth would not be heated for a longer time in summer.Thus, the correct answer is -
Yes, there would still be seasonsNo, the temperature difference between the seasons would not be as great.Learn more about the earth's tilt:

Discuss how constraints related to biology and management affect the choice of a crossbreeding system. Please be descriptive.
Answer:
Some important constraints:
-Plant breeding: autogamy and allogamy, self-sterility, etc
-Animal breeding: trait compatibility
- Breeding systems in general (i.e., both in plants and animals): barriers for sexual reproduction
Explanation:
Crossbreeding systems consist of the breeding between two breeds in order to develop progeny with particular advantageous phenotypic traits. In-plant crossbreeding systems, it is imperative to have into account whether the plant is autogamous (reproducing by self-pollination) or allogamous (reproducing by cross-fertilization), because it will affect the fitness of the progeny resulting from these breeds. Moreover, the biological mechanisms of self sterility and compatibility must be also taken into consideration. In-animal breeding systems, it is important to have into consideration that phenotypic traits we desire to obtain in the progeny must be compatible between races. In addition, the barriers for sexual reproduction are also an important issue both in plant and animal breeding systems, it thus being impossible, for example, to get a breeding between Chihuahua and Great Dane dogs.
