Lab apparatus:
- Analytical balance with 0.1 g precision (at least)
- Spatule
- Burette (0.1 mL precision) plus erlenmeyer or a graduated volumetric flask.
- Magnetic agitator
Safety precautions:
- Use gloves of the proper material
- Use safety googles
- Wear lab coat that fits you
<span>- Know where the safety equipment is located</span>
It helps improve spike stability by alternating between crops with deep roots and those with shallow roots. Pests are also put off because their food source keeps changing.
I think the correct answer from the choices listed above is option D. An increase in corn output resulting from genetic engineering, the invention of the air conditioner and the invention of LCD televisions are all example of technological progress. They make use of the present knowledge and making advantage of it to help the lives of people.
The correct answer is B. S-curve
Explanation
There are two models of population growth. One of them is the J-curve in which the population grows constantly without stabilizing, forming a J-shaped graph. Second, the S-curve is a model in which the population grows to a point, and from there it stabilizes, forming an S-shaped graph. According to the above, bacteria that divide rapidly until they run out of space and their growth slows down stabilizing the size of their population has an S curve model because the population does not grow unlimitedly but stabilized under specific circumstances. So, the correct answer is B. S-curve
