The building blocks of DNA are like alphabet letters, because they:
A. Are each associated with a particular sound
B. Can be used in a variety of languages
C. Each have an uppercase and a lowercase form
D. Spell out different instructions depending on their order

Answers

Answer: The answer is D.

Explanation: It makes the most sense and explains how both the aplhebet and DNA have simrialities.

The building blocks of DNA are like alphabet letters because they spell out different instructions depending on their order. Thus, the correct option for this question is D.

What are the building blocks of DNA?

The building blocks of DNA are known as nucleotides. These nucleotides are made up of three parts. They are as follows:

A phosphate group.A pentose sugar.Nitrogenous base.

These nucleotides are arranged by one another with the help of a linkage known as phosphodiester linkage. Nitrogenous base in nucleic acids like DNA includes Adenine, Thymine, Cytosine, and Guanine. In the DNA, they are represented as A, T, C, and G. Due to this, the building blocks of DNA are like alphabet letters.

Therefore, the building blocks of DNA are like alphabet letters because they spell out different instructions depending on their order. Thus, the correct option for this question is D.

what is dominant character ?

allele can be defined as a form of a gene which can be present as a pair shows either homozygous or heterozygous phenotype of a character.

these gene can express the phenotype either dominant or recessive form. In a cross between two organism, in F2 generation the offspring's are produced shows three phenotypes homozygous dominant, recessive, heterozygous dominant.

dominant allele can suppress recessive allele.

As with Part H. you have a total body concentration of 300 mOsM and body volume of 3 liters. You now add 2 liters of a 500 mOsM solution. The solution is equal parts NaCI (nonpenetrating) and urea (penetrating), so it has 250 mosmol/L NaCI and 250 mosmol/L urea. Answer the following questions about your new solution:
Drag the terms on the left to the appropriate blanks on the right to complete the sentences.
The solution is_______ osmotic to the body.
What is the concentration of nonpenetrating solutes (NP) in the solution?
What is the internal concentration of the body's cells? (All intracellular solutes are nonpenetrating.)

Answers

Answer:

- The solution is hyperosmotic to the body.

- What is the concentration of nonpenetrating solutes (NP) in the solution? 500 mosmol/L

- What is the internal concentration of the body's cells? (All intracellular solutes are nonpenetrating.) 300 mosmol/L

- When the cells reach equilibrium after addition of the solution to the body, has cell volume increased, decreased, or stayed the same? increased

- Based on your answer regarding water movement, the solution was hypotonic to the body's cells.

Explanation:

A hyperosmotic (or hypertonic) solution is a solution with a greater solute concentration. If a cell is placed in a hyperosmotic solution the water will leave the cell and the cell will shrink. Conversely, a hypotonic solution is a solution that has a lower concentration of solute. If a cell is placed in a hypotonic solution the water will enter the cell through osmosis and the cell increases in size. In this case, the NaCl is a non-penetrating solute, and thereby the concentration in the body's cells maintains constant. Moreover, urea is a penetrating solute, thereby it will penetrate in the cells until the equilibrium is reached (i.e., the cells will increase in volume).

Answer:In old stems the epidermal layer, cortex, and primary phloem become separated from the inner tissues by thicker formations of cork.

Suppose that you are an explorer who has found a new species of plant. Some of the plants have red flowers and some have yellow flowers. You cross a red-flowered plant with a yellow-flowered plant and all the offspring have orange flowers. What is the most probable explanation

Answers

Answer:

Incomplete dominance

Explanation:

In genetics, incomplete dominance refers to an inheritance mode in which two gene variants (i.e., alleles) of the same locus combine in a way that neither allele dominates the other. This phenomenon is similar to codominance, but in this last case, both alleles are dominant. Incomplete dominance produces a new phenotypic trait resulting from the combination of both non-dominant alleles. An example of incomplete dominance includes the pink color of snapdragons resulting from the cross of red-flowered snapdragons with white-flowered snapdragons.

Which processes produce the carbon dioxide from the original glucose molecule? Which processes do NOT produce CO2 molecules? (this is abt cell respiration)

Answers

Glycolysis in cellular respiration and during the process glucose is oxidised to carbon dioxide and water. Processes that produce: glycolysis,link reaction,the Krebs cycle and the electron transport chain

The process that is responsible for the production of carbon dioxide from the original glucose molecule is known as Cellular respiration.

What is Cellular respiration?

Cellular respiration may be defined as a biological process through which a form of sugar which is known as Glucose is transferred into energy in the form of ATP in the presence of oxygen. This energy is required to accomplish metabolic activities.

The complete reaction of cellular respiration is as follows:

Glucose + Oxygen → Carbon dioxide + Water + Energy (ATP).

The process that does not produce carbon dioxide molecules is the oxidation of food during respiration. In other words, it is known as Lactate fermentation. Lactate fermentation initiates with glycolysis and forms lactate.

Therefore, the process that produces carbon dioxide and the process that does not produce carbon dioxide is well described above.
