Motor, sensory
4
Root hairs are important to a plant because they
Contain xylem tissue
Anchor a plant in the soil
Increase surface area for absorption
Store starches
5
What allows water to move through the phloem of a plant?
Transpiration through the stomata
Root pressure
Gravity
A difference in osmotic pressure between the source and sink
6
What portion of your immune system is responsible for this effect?
Non-specific
Macrophages
Humoral
Cell-mediated
7
The rate of flow of water in the xylem is regulated by
the number of companion cells in the phloem.
active transport.
passive transport by the pith.
the force of transpirational pull.
8
Which of the following describes the autonomic nervous system?
It is part of the central nervous system.
It regulates the internal environment of the body.
It integrates sensory inputs to the brain.
It carries signals to skeletal muscles.
9
What is the difference between the responses of B cells and cytotoxic T cells?
B cells kill pathogens; T cells kill hosts
B cells-active immunity; T cells passive immunity
B cell-cell mediated; T cells humoral
B cells secrete antibodies; T cells kill cells.
10
Why does altruism occur in terms of natural selection?
It helps maintain Hardy Weinberg equilibrium.
