Answer:


Well, you may have errors in measuring the concentration of your solution, or in weighing the potato slices before and after the experiment. If you use different potatoes, or different parts of the potato are different (eg one part for some reason dryer) then that could add to the error. If you put a potato into an isotonic solution it should remain the same weight, but if you have more solute in the water than in the potato, water from the potato will be drawn out (like salting a snail or tomato), but if the water has less solute than the potato, it will be drawn into the potato, making it heavier.

Answer:

In the experiment it includes several separate tests and errors that can be easily occurring. One of the errors is the potato cores were not necessarily all the same weight to even begin with. However, another source of error is the cores were not exactly completley covered by the solution, which is due to the larger beaker.

Cell growth and cell division are processes that are regulated by specific genes. Mutations in these
andre [41]

Answer:

I'm pretty sure it's C) Accumulated

Explanation:

Accumulated verb in the dictionary is: past tense: accumulated; past participle: accumulated

So I would think that it does not have anything to do with division of cells, or the process.

I'm sorry if this is not right. I hope it is though.

Have a nice day! Bye :)

If a plant is inherited by complete dominance where homozygous dominant is a red flower color and homozygous recessive is a whit
WITCHER [35]

Answer:

Genotype of parents is Rr

Explanation:

Let the allele for red flower be represented by "R" and the allele for white flower be represented by "r"

Allele for red color is dominant over allele for white color.

Co-dominant causes the expression of characteristics associated with dominant allele only.

Genotype of parents is Rr

Rr * Rr

RR, Rr, Rr, rr

"rr" is white colored flower

"RR and Rr" is red colored flower

Ftsz is a bacterial cytoskeletal protein that forms a contractile ring involved in bacterial cytokinesis. its function is analog
natita [175]

The function of the FtsZ is analogous to the cleavage furrow of the cells of eukaryotes of an animal. This is a protein encoded by the gene FtsZ in which this protein has the capability of producing a new cell wall that is in between the dividing cells.

An individual's complete collection of genes is called his or her:
BabaBlast [244]

The right answer is genotype.

The genotype is the information carried by the genome of an organism, contained in each cell in the form of deoxyribonucleic acid DNA. Carried by the chromosomes, it is located inside the nucleus in eukaryotes and in cytoplasm in prokaryotes.

In humans, it is estimated that the number of genes is between 25,000 and 30,000.

Ling made a study chart for science class.
aliina [53]

Alyssa's additional observation would be cell Y having a larger vacuole than cell X. The third option is the correct one.

<h3>Plant cell vs animal cell</h3>

From the observations, both cells are eukaryotic. This is because:

  • cell X has lysosomes which are only found in eukaryotic cells
  • cell Y has a nucleus which also peculiar to eukaryotic cells only

Lysosome houses digestive enzymes and is found mostly in animal cells. Only a few plant cells have lysosomes.

Thus, the lack of a lysosome means that cell Y is a plant cell while the presence means that cell X is an animal cell.

Generally, plant cells have larger vacuoles than animal cells.
