 The solute potential is expressed in the formula P= – iCRT, where i = the ionization constant, C = the molar concentration , R = the pressure constant (R = 0.0831 liter * bars/mole * K), and T = the temperature in K (273 + °C). At atmospheric pressure and 25°C has an osmotic potential - A 0.15 M NaCl solution contains 2 ions, Na+ and Cl- (where sucrose stays as one particle); therefore i = 2, and the water potential = -7.4 bars. 
Water will move into the cell by osmosis from 0.1 to 0.15.

Answer:

The correct answer is -7.429 bars.

Explanation:

The solute potential inside the cell is calculated by the formula = -iCRT

Here, i refers to the number of ions, C refers to the concentration of solute, R refers to the gas constant, and T is the temperature (K)

The concentration within the cell of the plant is 0.15 M for NaCl, i = 2, R = 0.0831 and T = 298 K or 25 degree C.  

Solute potential = - (2 * 0.15 * 0.0831 * 298) = -7.429 bar

natulia [17]

Answer:

Processing and packaging of cellular materials prior to export

Explanation:

Our cells contain many different organelles. Every organelle has its own function, just like every organ in our bodies.

The Golgi apparatus is one of these organelles. It can be found in most eukaryotic cells. Its purpose is to transport, modify, and package proteins and lipids before they're delivered to other parts of the body. This is the function the organelle with smooth-sided channels Megan is observing would need to perform in order to be identified as the Golgi apparatus.

19. If a scientist needs to use a large dataset to explore how corn grows in different soils, how would this data be classified?
Illusion [34]

<u>ANSWER:</u>

The correct option is B- Qualitative.

<u>EXPLANATION:</u>

When the growth of corn has to be recorded, the quality of the corn grown in different soils needs to be recorded. Qualitative methods are best used to classify quality of anything.

Qualitative data basically is non-numerical data which in the case of corns can be the length of the corn plant, the sweetness of the corn kernel or the hardness or softness of the corn. This data cannot be recorded using numerical values and so other methods of data recording cannot be used.

If a homozygous black bull is mated with a homozygous white cow and the calf is gray, this could be an example of ___________. H
givi [52]

Answer:

Incomplete dominance

Co-dominance

Explanation:

Gregor Mendel discovered the principles that governs heredity, in which one of them is that an allele called DOMINANT allele, is capable of masking the expression of its variant allele called RECESSIVE allele in a heterozygous state. However, there has been genetic scenarios contrary to this his LAW OF DOMINANCE.

One of those Non-mendelian pattern of inheritance is a phenomenon called INCOMPLETE DOMINANCE, where an allele does not mask the expression of another completely, instead their combined state produces a third intermediate phenotype that is different from both parents. This is the case of the homozygous black bull mated with a homozygous white cow to produce a grey calf. The grey phenotype is an intermediate phenotype of both the black and white colours that forms due to incomplete dominance.

Another genetic scenario is called CO-DOMINANCE, where one allele is neither dominant nor recessive to the other allele, but instead both phenotypes becomes simultaneously expressed in the heterozygous offspring. In this case, the black bull and white cow were mated to form a heterozygous calf with both black and white spots.

Answer:

The only possible answer is D, which states that the population will reach 5000 and after that the growth will stabilise (exactly what would hapen in a logistic growth).

Which feature of the watson and crick model of dna structure explains its ability to function in replication and gene expression
Ymorist [56]

Answer:

The correct answer is reciprocity or pairing of the bases.

Explanation:

The fact that bases are reciprocal to one another (thymine and adenine, cytosine and guanine) means that the same information contained in one strand is also found in the other one. This led to the fact that the DNA molecule is the one that carries genetic information.
