Why do stems have bark? What does the phloem do?
Answer:In old stems the epidermal layer, cortex, and primary phloem become separated from the inner tissues by thicker formations of cork. Due to the thickening cork layer these cells die because they do not receive water and nutrients. This dead layer is the rough corky bark that forms around tree trunks and other stems.

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
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.

Imagine sperm and egg cells have 46 chromosomes like other cells in the body. That
is they have 46 chromosomes when a sperm cells fertilizes an egg cell. Would that
affect the total number of chromosomes in their offspring or children? Tell why or why
not.
Answer:
When an egg and sperm having 46 chromosomes similar to the body cells, their fertilization produces offsprings or children with 92 chromosomes which are double number of chromosomes as compared to parent cell. So they are not similar to parents. As we know that fertilization is the process of fusion of gametes and paring up of chromosomes. The offsprings are different from their parents in having more chromosome sets.
Explanation:
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.)
When the cells reach equilibrium after addition of the solution to the body, has cell volume increased, decreased, or stayed the same?
Based on your answer regarding water movement, the solution was ____ tonic to the body's cells.

300 mosmol/L
Stayed the same
300 mosmol/L
Hypo

decreased
stayed the same
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).

In one experiment, the heart rate of a mollusk at rest was measured at 0.3 cycles/s. How many times did the mollusk's heart beat in 1 min?
Answer:
18 times
Explanation:
Heart rate = 0.3 cycles/s
Heart rate = [tex]\frac{number of cycles}{time}[/tex]
number of cycles = heart rate x time
But, 1 min = 60 seconds
⇒ number of cycles = 0.3 x 60
= 18
Thus, the number of times that the Mollusk's heart beat in 1 min is 18.

Describe the
functions of the cell membrane
and cell wall
Answer:
cell membrane: provides protection for a cell . It also provides a fix environment inside the cell and the membrane has several different fonctions . One is to transport nutrients into the cell and also transports toxic substance out of the cell.
cell wall: cell wall is a structual layer sorrounding some types of cells , just outside the cell membrane . it can be tough , flexible ,and sometimes riding. it provides the cell with both structual support and protection , and also acts as a filtering machine.
A protein isolated from a thermophilic bacterium shows a molecular weight of 160 kD when eluted from a size-exclusion chromatography column, but when the purified protein is run on an SDS-PAGE gel, a single band of 80 kD is observed. These results tell us that the protein is eluting from the size-exclusion column as a
Answer:
as a dimer consisting of two identical monomers (80 kDa subunits) that are packed together via hydrophobic interactions
Explanation:
SDS-PAGE (sodium dodecyl sulphate–polyacrylamide gel electrophoresis), is an electrophoretic methodology used to separate proteins that have a molecular weight between 5 to 250 kDa. SDS is a well-known ionic detergent that is able to break hydrophobic interactions and hydrogen bonds. Moreover, size-exclusion chromatography is a filtration technique that separates molecules in solution according to their molecular size. In this case, SDS-PAGE showed that the target protein is composed of two identical subunits (monomers) of 80 kDa each, which were separated by the detergent and formed one single band in the SDS-PAGE gel.
Which processes produce the carbon dioxide from the original glucose molecule? Which processes do NOT produce CO2 molecules? (this is abt cell respiration)
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.

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.
