Answer:
okay, but bill nye notes for what? you need to be more specific
Answer:
In oxygenic photosynthesis, the first electron donor is water, creating oxygen as a waste product. In anoxygenic photosynthesis various electron donors are used. Cytochrome b6f and ATP synthase work together to create ATP. This process is called photophosphorylation, which occurs in two different ways.

I believe it would be mitosis.
Explanation:
The best answer - dermal tissue.
Dermal tissue in plants forms the first line of defense against physical damage and infection from the outside world.
Dermal tissue covers the outside of the plant, except in woody shrubs and trees, which have bark. The most common cell type in dermal tissue is epidermal cell. Generally, a thin waxy layer called a cuticle covers the epidermal cells and protects them.
Other cells in the dermal tissue are guard cells that surround the stomata, which are openings in the leaves. Gases enter and leave the dermal tissue through the stomata.
Answer:
C) binding to mRNAs and degrading them or blocking their translation
Explanation:
<u>miRNAs:</u>
miRNAs is the abbreviation of MicroRNAs. These are the small noncoding RNAs of ∼22 nucleotides which can not code for peptides. miRNAs are responsible for gene expression regulation at the level of post transcription. They can do so by forming complementary base pairing with target mRNA and inhibiting their translation.
They silenced mRNA by the following processes:
(1) Cleavage of the mRNA strand into pieces,
(2) stopping mRNA from translation into proteins by ribosomes.
(3) Shortening of mRNA poly(A) tail and destabilizing it.
