A cell wall is a permeable layer found in plant cells which acts as a membrane through which water molecules can pass through while animal cells do not have cell walls.. they just have a cell membrane which is selectively permeable to some chemicals or substances.. water does not move from the region of higher to lower concentration in animal cells
In short, plant cells have cell walls that allow osmosis while animal cells do not have cell walls for osmosis to take place
hope it helps you :)
Instead in our hands... something else happens rills or groove shaped lines are formed in our fingers.. it is an adaptation for our body to provide for some friction in water...
The type of evolutionary mechanism that occurred was natural selection
Answer:
RNA splicing is the intron removal and exon binding in the mRNA before leaving the nucleus.
Explanation:
Alternative splicing of identical RNA transcripts into different cell types can produce different mature mRNA molecules that translate into different polypeptides.
The genetic information encoded in the AND is transcribed to a copy of RNA (primary transcript). This copy is then modified with the addition of the 5 ’cap (CAP) and the poly-A tail, the excision of the introns and the union of the exons (splicing). The mature mRNA then goes to the cytoplasm, where it is translated into proteins.
Option 2 is the correct answer. it doesn't follow the trend.
Answer:
true
Explanation:
you frequently need a control which shows the experiments to stay the same. controls are very important.
