Answer:
the answer is C non-specific immunity
Explanation:
B) The water molecules remain together. The salt molecules break apart.
Step-by-step explanation:
When the salt is being place upon the water, the sodium in salt becomes attracted to the water molecules. Both H20(water) & NaCI (salt) start to become drawn, during this reaction. This causes water to remain together, while the salt is broken apart and dissolves. Hope this helps!
Answer:
Touching, Smelling.
Explanation:
Touching will be useful to detect stimuli like coldness and hotness.
Smelling on the other hand will help to make observations on smell and change in smell. These two are among the five senses that we use to make observations as we record what we see, hear, touch and feel, smell and taste.
Answer:
E2F transcription factors
Explanation:
The E2F transcription factors (TFs) encode intracellular factors associated with the control of the cell cycle. E2F are TFs that bind to promoter consensus sequences in order to activate transcription. These TFs control the expression of target genes involved in cell proliferation including, among others, genes for DNA replication and mitotic activation. Moreover, the E2F proteins also may act as a link between cell fate and the cell cycle. The retinoblastoma (Rb) is a protein that modulates the activity of the E2F family of TFs, and it has been shown that the Rb/E2F pathway is a key molecular mechanism associated with cell proliferation.
