Answer:
B. Rock Layers
Explanation:
The definition is a layer or a series of layers of rock in the ground.
Answer and Explanation:
12. The water has a lower osmotic pressure than the cell sap of the root hairs. Due to the osmotic difference water is drawn by osmosis across the cell wall and cell membrane into root hairs. Water moves by osmosis into adjacent cortex cells and their osmotic pressure is lowered drawing water by osmosis. Water passes to the successive cortex cells and through the endodermis to the xylem vessels. At the leaves, the xylem passes into the petiole and then into the veins of the leaf. Water leaves the veins and enters the cells of the spongy and palisade layers.
13. Food and other manufactured material are translocated by the phloem. They enter the sieve elements through plasmodesmata connecting them to adjacent companion cells which are sites of high metabolic activity. The manufactured food are translocated through sieve tube along the cytoplasmic strands.

The two major components of the tobacco mosaic virus were:
1. Protein Coat/Capsid: Each rod consists of about 2130 elliptical protein subunits (capsomers). They are closely packed together and arranged in a helical fashion
</span><span>2. Nucleic Acid: It is a single-stranded RNA helix having a diameter of 80 Å.

Answer:
monomers
Explanation:
The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts.
