A flask containing 100ml of YNB broth was inoculated with approximately yeast cells. The flask was incubated at 37 degrees Celsius (100rpm). Samples were periodically collected and their absorbance (optical density-OD) was measured: Using the given data (shown in photo) calculate the doubling time of this microorganism (FIRSTLY, you have to determine the exponential phase!)

The time it takes for the yeast population to double is 1 hour.

Explanation:

Convert the OD to an approximation of the number of cells present in the broth. Do this by multiplying the OD value with 3 x 10^7.

The exponential phase of growth for the yeast cells is from

time t = 0 hours to time t = 5 hours

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
