How does the sugar concentration affect the size of a cell?

1 answer:

4 0

If sugar concentration within a cell is high/rises, then water will enter the cell increasing the volume of cytoplasm within the cell and hence the volume/size of the cell itself;

Alternatively, if the sugar concentration within a cell is low/falls, then water leave the cell decreasing the volume of cytoplasm withing the cell and thus the cell will get smaller.

In humans, the allele for the dimple trait is dominant over the allele for the non-dimple trait, and the allele for the cleft ch

gayaneshka [121]

Answer:

Probability of Dimples and a cleft chin among their offspring = 1/4

Probability of no dimples and a non-cleft chin = 1/4

Explanation:

the allele for the dimple trait D is dominant over the allele for the non-dimple trait d.

the allele for the cleft chin trait C is dominant over the allele for the non-cleft chin trait c.

Mr. Smith has heterozygous alleles for both traits.

Mrs. Smith does not have dimples, nor does she have a cleft chin

Mr Smith DdCc x. ddcc

Probability of Dimples and a cleft chin among their offspring = Dd x dd = 1/2

Cc x cc = 1/2 = 1/2*1/2 = 1/4

Probability of no dimples and a non-cleft chin = Dd x dd = 1/2, Cc x cc = 1/2 = 1/2*1/2 = 1/4.

How many possible open reading frames (frames without stop codons) are there that extend through the following sequence? 5'... C

fenix001 [56]

Answer:

There are 4 reading frames without stop codons.

Explanation:

1) To find the possible reading frames you need to separate your sequence in codons (trios) for the 5'-> 3' sense, first, excluding the first nucleotide, then excluding 2 nucleotides and then not excluding nucleotides.

5'... C TTA CAG TTT ATT GAT ACG GAG AAG G... 3' NO STOP CODON

5'... CT TAC AGT TTA TTG ATA CGG AGA AGG... 3' NO STOP CODON

5'... CTT ACA GTT TAT TGA TAC GGA GAA GG... 3'

2)Then you find the complementary sequence (which you already have)

3'... GAA TGT CAA ATA ACT ATG CCT CTT CC... 5'

3'... GA ATG TCA AAT AAC TAT GCC TCT TCC... 5'

3'... G AAT GTC AAA TAA CTA TGC CTC TTC C... 5'

3) Next, you have to obtain the reverse complementary

CCT TCT CCG TAT CAA TAA ACT GTA AG NO STOP CODON

CC TTC TCC GTA TCA ATA AAC TGT AAG NO STOP CODON

C CTT CTC CGT ATC AAT AAA CTG TAA G

4)Now you need to find start (AGT in terms of DNA) and stop codons(TAA, TAG, TGA, also in terms of DNA), in 5->3 and de reverse complementary.

As you can see, you have for open reading frames that lack of stop codon, unfortunately, they also lack of AGT, the start codon.

I added a table where you can find thestart and stop codons as well as the proteins that they translate to in terms of RNA.

I hope you find this information interesting and useful, good luck!

To be considered acid rain, precipitation would have to be?

Korolek [52]

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
