From your genetics lab, Agrobacterium tumefaciens gram-positive bacterium was used during your experiment on genetic manipulation of a corn plant
Rhizobiaceae is a family of bacteria that includes Agrobacterium tumefaciens. Gram-negative and aerobically growing, these bacteria don't produce endospores. The cells have one to six peritrichous flagella and are rod-shaped and motile. Cells can exist alone or in pairs and range in size from 0.6 to 1.0 m by 1.5 to 3.0 m.
Agrobacterium tumefaciens is a gram-negative bacterium that causes tumors in plants through horizontal gene transfer. In a variety of plant species, Agrobacterium tumefaciens has been widely exploited as the primary agent in the generation of transgenic plants. A soil phytopathogen called Agrobacterium tumefaciens naturally infects plant wound sites and causes the disease known as crown gall by the transfer of (T)-DNA.

Answer:
b. the positive feedback's effector responses are in the same direction as the initiating stimulus rather than opposite of it
Explanation:
Both positive and negative feedback have the same components:
1. Stimuli - external or internal
2. Sensors - detect the stimuli
3. Control center - processes the information (CNS)
4. Effectors - activated by control center
Negative feedback loops act to oppose the stimulus.
Unlike negative feedback loops, positive feedback loops amplify the starting signal.
Golgi bodies package and store proteins. They also store lipids.
Answer:
I think it's sedimentary rock
