Biology
1 answer:
Pavlova-9 [17]3 years ago
8 0

Answer:

Plants is the first organisms to receive Carbon as CO2, to initiate the process of photosynthesis. Through this process the plants is serving as the primary producers, and sources of carbons for other organisms.These organisms  (the consumers) must feed on  plants  to trap Carbon, when they consume plants to derive carbohydrate(glucose),proteins and lipids.

In the terrestrial food web above, what would be the effect of a farmer introducing a rat poison in to the ecosystem that is tox
love history [14]

Answer:

As explained below

Explanation:

  • The terrestrial food web is a food web that is characterized by all land animals and is largest terrestrial food chain on earth as the farmer tends to introduce a rat poison in this food web the rat may get killed by the medicine but if the same rate may be eaten by a snake the poison that killed the rat may infect the snake.
  • Hence the pollutant may climb up the ladder and intoxicate the hawk that depends on small animal for prey which may be further eaten by a man or other animal like a cat may then spread this disease or the infection to other upwards in the food chain and thus the process of Biomagnification takes place in the ecosystem.

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.
