Water is a small molecule that easily diffuses through a cell membrane despite the lipid tails. The diffusion of water is what we call “osmosis”. Oxygen is a small molecule and it is also nonpolar, so it easily passes through a cell membrane.
It is able to pass through because of the high osmotic pressure difference between the inside and outside of the cell.
Most of the water passes through channels called “aquaporins”.
Answer:
TCAATGCT. GTCGGAAC. TAATCGGA
Explanation:
Matching base pairs in a nucleic acid sequence may form a double-stranded structure.
C-A-T-G with a complementary base would be is G-T-A-C.
Continental Drift Theory!!
Hope this helps...have a good day!!;)
Answer:
Food chains are a pictorial description of an ecosystem: what eats what. This helps scientists track the web of interdependence. If one important component in a chain is removed or affected, we can make predictions about how this might impact the entire ecosystem. We can track the effects of disruptions on a system.
The correct answer is: Differentiate
Every cell in a multicellular organism has an identical genome, and yet, there are various cell types. These varieties are the result of highly controlled modifications in gene expression (different sets of genes must be turned on and off).
Cellular differentiation almost never involves a change in the DNA sequence itself. Therefore, different cells can have very different physical characteristics regardless of having the same genome.
