A)Exons 2 and 3 must have the same number of nucleotides. B)Exons 2 and 3 must contain an integral number of codons (that is, the number of nucleotides divided by 3 must be an integer). C)Exons 2 and 3 must contain a number of nucleotides that when divided by 3, leaves the same remainder (that is, 0, 1, or 2). D)Exons 2 and 3 must have different numbers of nucleotides. Multiple Choice

Answers

Answer 1

Answer:

Statement C is the only one that is necessarily true for exons 2 and 3. It is also true for exons 7 and 8. While statements A and B could be true, they don’thave to be. Because the protein sequence is the same in segments of the mRNA that correspond to exons 1 and 10, neither choice of alternative exons (2 versus 3, or 7 versus 8) can alter the reading frame. To maintain the normal reading frame—whatever that is—the alternative exons must have a number of nucleotides that when divided by 3 (the number of nucleotides in a codon) give the same remainder. Since the sequence of the a-tropomyosin gene is known, it is possible to check to see the actual state of affairs. Exons 2 and 3 both contain the same number of nucleotides, 126, which is divisible by 3 with no remainder.

Answer:

Copying of DNA to form an mRNA strand

Explanation:

In transcription, DNA is copied to form an mRNA strand with complementary bases.

The DNA strand being copied during the process is called the template strand, and the mRNA that is made will be created from that strand.

This is the first step of protein synthesis.

This strand of mRNA is further used during translation, where it is used to code for amino acids to make proteins.

So, the correct answer is Copying of DNA to form an mRNA strand

Answer:  The correct answer is Copying of DNA to form an mRNA strand

B. 30% of the sun’s energy cannot be absorbed by producers because it is in the wrong wavelength of light. C. Producers only absorb 40% of the sun’s energy, most of which is lost during photosynthesis. D. Producers absorb 5% of the sun’s energy, and reflect 5% of the sun’s energy.

Answers

Answer:

A. Producers are able to convert 40% of the sun’s energy into chemical energy.

Explanation:

Energy in an ecosystem must be transferred in the ecosystem. The primary source of energy in an ecosystem is the sun. The terrestrial ecosystem mostly consists of plants and marine ecosystems. As energy flow in an ecosystem is unidirectional. It passed from the organism from one tropic level to another. Only 10% of the energy is available to them.

The DNA molecule could be compared

Answers

Answer:

The correct answer is -To a ladder.

Explanation:

Most commonly DNA molecule is considered and compared to a twisted ladder as the structure of DNA can be compared to a ladder. It makes the side of the ladder by an arrangement of alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder.

Nitrogenous bases that are purine and pyrimidine make up the 'rungs' or steps of the ladder and also bind with hydrogen bonds with one other in the rug as two bases make a single rug, and are attached to the backbone where the deoxyribose (sugar) molecules are located.

Jaleel

[tex]2(x - 2) + 2 = 2x - 4 + 2 = 2x - 2[/tex]

Lisa

[tex]2(x - 2) + 2 = 2x - 2 + 2 = 2x[/tex]

Who is correct

Analyzing the solutions

For, Jaleel; we have:

[tex]2(x - 2) + 2 = 2x - 4 +2[/tex] --- this is correct

[tex]2(x - 2) + 2 = 2x - 2[/tex] --- this is correct

For Lisa, we have:

[tex]2(x - 2) + 2 = 2x - 2+2[/tex] --- this is incorrect because:

[tex]2(x - 2) + 2 \ne 2x - 2+2[/tex]

Many plant pathologists believe that plant resistance is based upon the interplay of different signaling molecules? Justified.

Answers

Answer:

Yes.

Explanation:

Many plant pathologists believe that plant resistance is based upon the interplay of different signaling molecules because plants have various signaling molecules that plays a great role in their growth and development. Ethylene, auxin, cytokinins, gibberellins, and abscisic acid are the growth regulators that controls the growth of plants in different conditions i.e. in resistance. These signals leads the plant to take measures in difficult situations experience by the plants so in this way the plant is resistance to the harsh environmental condition.

When observing a plant cell under a microscope, what parts do you think would be big enough to see?

Answers

Answer:

Explanation:

There are a few key structural differences between plant cells and animal cells.

Below are a few of the main ones:

Plant cells are generally larger than animal cells.

Only animal cells have lysosomes (however, recent, and controversial, research suggests that some plant cells may have lysosomes), and only plant cells have chloroplasts.

While plants cells have a rigid cell wall, animal cells have a thin and flexible plasma membrane.

Plants cells have a large central vacuole and animal cells have many small vacuoles

When observing a plant cell under a microscope, one can see large interlocking rectangular blocks. Around each cell, the cell wall is clearly visible. When stained, the cell wall is somewhat thick and visible. The cytoplasm is also lightly stained, with a darkly stained nucleus at the cell's periphery.

What is a plant cell?

A plant cell is a eukaryotic cell with something like a true nucleus and organelles that perform specific functions. However, some organelles found in plant cells differ from those found in other eukaryotic cells.

At the time of observing a plant cell under a microscope, person can see large rectangular blocks as well as cell wall is clearly visible.

When stained, the cell wall is thick and visible. The cytoplasm will also be lightly stained, with stained nucleus at the cell's periphery.

Thus, these structures can be visible under a microscope.

e. The vesicles derived from the Golgi apparatus produce a cell plate at the middle of the cell that eventually forms the new cell wall.

Answers

Answer:

d. The cell begins to elongate and the two poles have an equivalent collection of chromosomes.

Explanation:

The cell cycle is a fundamental cellular process by which a parent cell divides into two or more daughter cells. In somatic cells, this cycle can be divided into two major phases: interphase, where the cell prepares for its division, and mitosis or 'M phase'. The M phase can in turn be divided into four stages: 1-prophase (also divided into early prophase and prometaphase), 2-metaphase, 3-anaphase, and 4-telophase. During prophase, chromatin condenses, thereby forming visible chromosomes. Subsequently, during metaphase, the sister chromatids (i.e., the two identical halves of a single replicated chromosome) align along the middle of the cell at the metaphase plate by attaching their centromeres to the spindle fibers. Next, during anaphase, sister chromatids are separated and move to opposite poles of the cell, pulled by the mitotic spindle fibers. At the end of anaphase, the microtubules of the mitotic spindle pull the two sister chromatids toward opposite poles, thereby the cell gets begins to lengthen. Finally, during the telophase, daughter chromosomes arrive at opposite poles and uncoil, while daughter nuclei begin to form at the two poles and nuclear envelopes are formed.

Answers

Explanation:

Biomolecules like carbohydrates, fats etc. are well known for their energy storing abilities. Glucose, as a carbohydrate, is the most used source of energy but is stored in excess as glycogen in the muscle and liver cells.

However, fats are far more efficient in storing energy than carbohydrates or proteins because they give more ATP per molecule. Fats are stored in tissues of the body called ADIPOSE tissues. Hence, the richest source of stored chemical energy in the body is FATS IN TISSUES.
