Answer:
<h2>
1. Protein synthesis on attached ribosomes:</h2><h2>Destination: cell membrane.
</h2><h2>One general function
: to be a surface receptor.</h2><h2>2. On free ribosomes- destination: cytosol
</h2><h2>One general function: microfilaments.</h2>
Explanation:
Proteins are synthesized by the process known as translation. Translation occurs by ribosomes as they can be attached with endoplasmic reticulum or they can be free in the cytosol.
Protein is synthesized according to the sequence of nucleotide on mRNA.
Newly synthesized protein contain signals sequence which targets then for their final destination.
1. ONE ultimate destination of a protein produced on an attached ribosome: These proteins, after synthesis enter into ER and then according to the signal sequence, they reach to their final destination.
Example: cell membrane.
One general function of the protein
- to be a surface receptor
2. One ultimate destination of a protein produced on a free ribosome: cytosol
One general function of the protein: microfilaments
It's body cells would have 40 chromosomes and its gametes would contain half of the total genetic information, 20 chromosomes.
Answer:
Natural selection is the process through which populations of living organisms adapt and change. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.
Explanation: I hope this is right?
Answer:
Option A, Competition has restricted the ranges of both species
Explanation:
When two species which depend on the exactly same kind of resources, get into a mode where they prefer to stay in two different ecosystems without interfering each other’s circle and thus they get excluded from each other due to competition. This phenomenon of the ecosystem is called Competitive exclusion
According to Gause's Law of competitive exclusion two species which are competing for similar kind of resources are unable to stay together.
Hence, option A is the correct choice.
