Dandelions grow quickly and produce many seeds, ensuring that at least some plants will survive and produce seeds themselves. Wh

Pani-rosa [81]

Species strategies to survive and successfully reproduce define three basic survivorship curves. The survivorship curve type III is the one that best represents the Dandelion plants.

------------------------------

According to the species strategies to survive, reproduce, and ensure their reproductive success, we can mention three basic curves,

Type I.

Mortality often occurs at the end of the cycle, representing species with low mortality.

Organisms exhibiting this type of survivorship curve have long life cycles and high probabilities to survive until they are old enough.

These species have few descendants and spend too much time and energy in parental care to ensure their reproductive success.

Type II.

The probabilities of dying are equals all along the cycle, at any age interval.

The number of dead individuals remains constant from the beginning to the end of the life cycle.

These species have reduced offspring, and they ensure their reproductive success by providing some significant parental care.

Type III.

Significant mortality during the early stages of life.

Only a few individuals reach the later life stages, getting to survive their first period of life. Survivors usually have a long life.

These species produce large offspring at the same time, but they provide little or no parental care.

The reproductive success of these species depends on the number of descendants and not on the parenting time spent.

According to this information, and the characteristics of the Dandelions, we might assume that this species is represented by type III curve.

imagine a cell-surface receptor protein is being newly synthesized. How can it get into the membrane that it will ultimately be

motikmotik

Answer:

the steps for a new receptor synthesis:

Explanation:

Do not forget the steps vary from an eukarityc cell to prokarityc one.

IN AN EUKARYOTIC CELL:

1- Transcription: in the nucleus, mRNA is synthesized from the DNA sequence that codifies the protein. Exons are spliced if needed by spliceosomes.

2- From nucleus into cytoplasm: mRNA goes through nuclear membrane into the cytoplasm were ribosomes, substrates for protein synthesis and other organelles are.

3- Ribosomes recognize a signal in mRNA and start reading the genetic code, three consecutive nucleotides at a time and adjust the correspondent tRNAs (tRNAs carry the aminoacids)

4- Peptide bonds are formed between consecutives aminoacids, and a polypeptide is build up according to the mRNA sequence.

5- (The mRNA has a signal that is recognized by the rough endoplasmic reticulum) The peptide goes into this reticulum (RER) and then into Golgi apparatus. (more chemical modifications are made if needed). By this moment the protein has an inserted portion in a lipid membrane.

6- The protein is transported in a vessel that finally fusions with cytoplasmic membrane and the receptor is in destiny. Hydrophobic aminoacid sequences are inserted in membrane.

IN A PROKARYTIC CELL:

1- Transcription (no splicing is needed, there are not exons)

2- There are not nucleus and cytoplasm divided (no transport)

3- Ribosomes recognize a signal in mRNA and start reading the genetic code, three consecutive nucleotides at a time and adjust the correspondent tRNAs (tRNAs carry the aminoacids)

4- Peptide bonds are formed between consecutives aminoacids, and a polypeptide is build up according to the mRNA sequence.

5- The mRNA has a signal that is guides the growing protein to cellular membrane. Hydrophobic aminoacid sequences are inserted in membrane.
