bacteria culture starts with 400 bacteria and grows at a rate proportional to its size. After 4 hours, there are 9000 bacteria.

yawa3891 [41]

Answer:

A) $P = P_0 e^{rt}$

B) $19564$

C) $5.5$ or $6$ hours

Explanation:

A) The formula that can be used for bacteria after "t" hours is

$P = P_0 e^{rt}$

Where ,

$P$ represents the population after "t" hours

$P_0$ represents the initial population.

$r$ represents the rate of growth of population

$t$ represents the time taken by the population to grow

B) Here let us first find the rate of population growth.

$9000 = 400 * e^{r*4}\\3.11 = r* 4\\r = 0.778$

Thus, the population of bacteria after 5 hours

$P = 400 * e^{0.778 * 5} \\P = 400* 48.91\\P = 19564\\$

C)

$30000 = 400 * e^{0.778 * t) \\\\4.317 = 0.778 * t\\t = 5.549\\or t= 5.5 or 6$

Explain why having more red blood cells per cm3 of blood is an advantage to an athlete.

leva [86]

Answer:

Haemoglobin carries oxygen, therefore, more oxygen can be transported to cells such as muscle cells. More oxygen transported to cells results in more aerobic respiration of cells such as muscle cells.

Both aerobic and anaerobic respiration yield a net gain of ATP molecules to be used as energy for living things. The processes o

pshichka [43]

Correct answer: C). Oxidative phosphorylation

Oxidative phosphorylation gives a basic unit of energy for all the metabolic processes called as ATP, it is a highly efficient metabolic process which is known to produce a large amount of ATP.

During the process of oxidative phosphorylation, electrons are exchanged between the molecules, that creates a chemical gradient, which is required for the production of ATP. It is known to produce more ATP called the energy currency of cell that any other cellular respiration. It produces 90% of the total ATP synthesized in the cell.

4. A single-celled organism that a student observed under a microscope is shown below.

Katyanochek1 [597]

Explanation:

D. The organism is eukaryotic because it has membrane-bound organelles.

Cells are the basic microscopic units of all organisms. There are two cell types, Prokaryotes and Eukaryotes.

Prokaryotic ( meaning pro: before and Karyon: for kernel/nut) describes organisms which don’t have a cell nucleus or other organelles surrounded by membranes. Eukaryotic (eu meaning true), are organisms with a cell nucleus and several other organelles surrounded by membranes. Example prokaryotes do not contain: nuclei , Golgi apparatus, chloroplasts, mitochondria

<em>Both may contain a cell wall (seen in eukaryotic fungi and plant cells)</em>

<em />

Arranged in a phospholipid bilayer, the membrane is semi-permeable; allowing entry into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water and hydrophilic molecules to move across the membrane along the concentration gradient.

Their structural components (i.e. their makeup) determine their function (what they do) . For instance, photosynthesizing cells in algae and plants have structures called chloroplasts. These contain chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates. In specific cell types, collected proteins may function as a unit called an organelle. Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they:

may increase metabolic reaction efficiency; they allow cells to concentrates smaller fractions of enzymes and solutes
separate proteins and molecules that me harm the cell by parceling them into membrane-bound organelles for example, proteaseas bound within lysosomes can break down many structural proteins
