You start off with 100 E. coli cells known to divide every 20 minutes. Based on this information and using formulas for exponent

ial growth (Nt = No2n), growth constant (k = n/t (gen/hr), and generation time (g = t/n or 1/g (hr/gen), calculate the following: a. From the given information, what is the generation time? Remember it’s the length of time (in hours) for the population to double.

Answer:

21 minutes or 0.35 hours

Explanation:

The formula for exponential population growth is

A = A_0* e^{kt}\\

where

A_0 = initial population of E.coli i.e 100

k is the rate of population growth i.e 2 as the population doubles

t is the time period i.e 20 minutes

Substituting the given values in above equation, we get -

A = 100 * e^{2 * \frac{20}{60} }\\\\A = 195

Generation time

G = \frac{t}{3.3 * log \frac{194}{100} } \\G = \frac{t}{0.949} \\G= 21 minutes

or 0.35 hours

STALIN [3.7K]

Answer:

Explanation:

The main  function of the plasma membrane is to protect the cell from its surroundings. Made of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules it also regulates the movement of substances in and out of cells. Plasma membranes must be very flexible in order to allow certain cells, such as red blood cells and white blood cells, to change shape as they pass through narrow capillaries. Membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors, which then trigger intracellular responses. Some viruses, such as Human Immunodeficiency Virus (HIV), can intercept  these receptors to get into the cells, causing infections.

What is the term for a fruit that develops from tissues other than the ovary?
bekas [8.4K]

The correct answer is D. Accessory fruit

Explanation.

Fruits are structures that develop from the fertilized ovary of plants and that contain the seed of it, this includes simple, aggregate and multiple fruits. However, there is one type of fruits that do not develop from ovary but from other tissues that are usually near the ovary, these fruits are called accessory or pseudo fruits as they do not fit completely the definition of regular fruits, this includes fruits such as strawberries or pineapples that develop from tissues different to the ovary.
