A group of biology students conducted a lab to study the effect of water on plant growth. They used the following procedure:

1 – Germinate nine bean seeds.

2 – Put three bean plants each into three identical pots containing the same weight and type of soil. Label the pots A, B, and C.

3 – Place pots in an area where they can receive the same amount of sunlight.

4 – Each day pour 30 mL of water into pot A, 20 mL of water into pot B, and 10 mL of water into pot C.

5 – Measure and record the height of the plants every other day for 15 days.

Recorded data:

Which was a limiting factor for this experiment?

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
