Answer:
Alternative splicing is a posttranscriptional modification that enables to produce many proteins from a single gene, thereby increasing its functional diversity. In mammals, alternative splicing has shown to be associated with the control of different signaling pathways in response to environmental conditions.
Explanation:
Posttranscriptional modifications are required for the maturation of primary RNA transcripts, and it is associated with the process of translation into proteins. These types of modifications include the alternative splicing in order to remove introns of pre-mRNA molecules, the addition of a cap to the 5' end and polyadenylation of the 3′ end of mRNAs, etc. For example, the polyadenylation (poly-A) of mRNA tails provide stability to these molecules, thereby they are more resistant to exonucleolytic degradation and thus can be translated into proteins.
The mechanism by which proteins synthesized in the cytosol are imported into the mitochondrial matrix is different from the mechanism by which proteins enter the nucleus, yet the two mechanisms do share some features. Indicate whether each of the following statements applies to nuclear import, mitochondrial import, both, or neither. Sort each statement into the appropriate bin.
1. The polypeptide to be transported into the organelle has a specific short stretch of amino acids that targets the polypeptide to the organelle.

PLEASE HELP. DONT ANSWER IF YOU DONT KNOW. Name any three specifications that reduce carbon dioxide expenditure and promote biodiversity.
Answer:
A carbon footprint is the total greenhouse gas (GHG) emissions caused by an individual, event, organization, service, or product, expressed as carbon dioxide equivalent.[1] Greenhouse gases, including the carbon-containing gases carbon dioxide and methane, can be emitted through the burning of fossil fuels, land clearance and the production and consumption of food, manufactured goods, materials, wood, roads, buildings, transportation and other services.[2]
In most cases, the total carbon footprint cannot be calculated exactly because of inadequate knowledge of and data about the complex interactions between contributing processes, including the influence of natural processes that store or release carbon dioxide. For this reason, Wright, Kemp, and Williams proposed the following definition of a carbon footprint:
Specifications that reduce carbon dioxide expenditure and promote biodiversity are as follows:
1. Provide tree plantation through urban afforestation.
2. It has low concentration of carbon dioxide as plants absorb this gas and release oxygen
3. By promoting fruits and shade for the neighborhood.
What is Carbon Dioxide?Carbon dioxide is defined as the chemical compound which is made up of molecules each containing a carbon atom bonded twice to two oxygen atoms and is found in the gaseous state at room temperature. In air, carbon dioxide is transparent to visible light but absorbs infrared radiation which acts as a greenhouse gas.
This is a minor component of the Earth's atmosphere at about 3 volumes in 10,000 employed by plants in the combustion of carbon-containing material, in fermentation, and in the respiration of animals and in the photosynthesis of carbohydrates.
Thus, specifications that reduce carbon dioxide expenditure and promote biodiversity are as follows:
1. Provide tree plantation through urban afforestation.
2. It has low concentration of carbon dioxide as plants absorb this gas and release oxygen
3. By promoting fruits and shade for the neighborhood.

What best describes the behavior of nonconservative elements in seawater?
The given question is incomplete due to missing options, however, the options for the question as follows:
A. Nonconservative elements are reactive in seawater and have a long residence time.
B. Nonconservative elements are reactive in seawater and have a short residence time.
C. Nonconservative elements are non-reactive in seawater and have a short residence time.
D. Nonconservative elements are non-reactive in seawater and have a long residence time.
Answer:
The correct answer is option C.
Explanation:
Non conservative components are components that enter the ocean water and have little concentration in the sea and show spatial variations. These components have short home time that is short replacements time and they are non responsive.
Constituents, for example, phosphate, nitrate, and different supplements, and broke up oxygen, carbon dioxide, and so on are non-conservative on the grounds that their concentrations are later altered by chemical reactions in the ocean.
Thus, The correct answer is option C.
A student recorded the height of each student in the school. She then made a bar graph of her results. She observed that
the results form a bell-shaped curve. The student could use her graph as evidence to support which argument?
Height is affected by multiple pairs of genes on different chromosomes.
The alleles for tall height and short height are codominant.
The allele for being tall is dominant to the allele for shorter heights.
There are three alleles for height that demonstrate incomplete dominance.
Answer:
Height is affected by multiple pairs of genes on different chromosomes.
Explanation:
The height is a quantitative trait, it is a phenotypic feature that presents a continuous range of variation in the population. The cumulative effects of many genes and the environment produce a normal distribution bell-shaped curve when they are drawn, this being a characteristic of quantitative genetic traits. Examples of quantitative traits include, among others, height, metabolic rate and weight.
The student could use their graph as evidence to support the argument that "The alleles for tall stature and short stature are codominant."
What is a Codominant gene?Codominant: Autosomal codominant inheritance is the condition in which the heterozygote has the characteristics determined by both alleles (dominant and recessive).
What is allele?Allele genes are those that occupy the same locus on homlogous chromosomes and are involved in determining the same character.
With this information, we can conclude that the genes alleles of the students in this class are codominant.

What are the values of a, b, and c in the quadratic equation 0 = 5x – 4x2 – 2? a = 5, b = 4, c = 2 a = 5, b = –4, c = –2 a = –4, b = 5, c = –2 a = 4, b = –5, c = –2
Hey there! :)
Answer:
The 3rd choice. a = -4, b = 5, c = -2.
Explanation:
Rearrange the quadratic equation given into the form 0 = ax² + bx + c:
0 = 5x - 4x² - 2 --> 0 = -4x² + 5x - 2
The corresponding coefficients for the a, b and c values are:
a = -4
b = 5
c = -2.
The given quadratic equation must be first rearranged in the form ax2- bx-c. From this, we can find the values of a= -4, b= 5, and c= -2
How can a quadratic equation be defined?Quadratics can be defined as a polynomial equation of a second degree, which implies that it comprises a minimum of one term that is squared. It is also called quadratic equations. The general form of the quadratic equation is ax² + bx + c = 0.
Quadratic equations are commonly used in situations where two things are multiplied together and they both depend on the same variable. For example, while working with the area, if both dimensions are represented in terms of the same variable, you use a quadratic equation.
Throwing a ball, shooting a cannon, diving from a platform, and hitting a golf ball are all examples of situations that can be modeled by quadratic functions.

Craig Mellow investigated RNA interference by injecting antisense and double-stranded RNAs into C. elegans. If the antisense and double-stranded RNAs were very similar, but not identical, to C. elegans mex-3, what would be the results of their experiment
Answer:
It is required that the seed region of the processed dsRNA molecule bind to the mRNA of mex-3 in order to inhibit its translation
Explanation:
Double-stranded RNAs are small interfering non-coding RNAs (about 20 nucleotides in length) that, after processing, can bind by complementary base pairing to RNAs and thus inhibit protein translation by a mechanism referred to as 'RNA interference' (RNAi). The base pairing is not always perfect; however, the guide strands of dsRNAs can conserve their ability to inhibit the translation if the complementarity is enough good to match target RNA sequences. The critical region in the dsRNA that is required to bind target RNAs is known as seed region, and consists of 6 to 8 nucleotides in length.

Construct at least two possible hypotheses for the student’s experiment
Answer:
OFFICIAL SAMPLE ANSWER (Do not copy verbatim):
Hypothesis 1: The natural nutrients in compost will cause the tomato plants to grow at a faster rate than they grow when given artificial fertilizer.
Hypothesis 2: The artificial fertilizer is formulated specifically for tomato plants, so it will cause the plants to grow at a faster rate than they grow when given compost.
Explanation:
If questioned for situation below.....
"Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops.
A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer.
"
1. compost pits and manure use, bio gas can be produced
2. using natural compost replenishes the soil fertility in the long run unlike the chemical fertilizers are two possible hypotheses for the student’s experiment
What are the basics of experiment ?The basics of experiment is to test the hypothesis what we set previously and it is a foundation of the scientific method, types of experiments include controlled experiments, field experiments, and natural experiments.
The key steps taken in scientific method are observations, ask a question, making of hypothesis, design and conduct experiment, result, accept or reject or repeat the hypothesis from result.
The most important parameter taken in an experimental set up is variable which can be dependent, independent and controlled variables where the independent variable is something which can not influenced by other factor.
A dependent variable can be changed by the influence of independent variable and Control variable can be used to check bias of experiment.
