An example of a haploid cell is the sperm cell. A haploid cell has a complete set of chromosomes. Through meiosis, a haploid cell called the gametes is produced. Haploid cells could also refer to the number of chromosomes in an egg or a sperm cell.

Answer:

Complete the following problems using the equation:

Students are not required to memorize this formula but must know the meaning of the symbols:

D = diversity index

N = total number of organisms of all species found

Σ = the sum of

n = number of individuals of a particular species

D is a measure of species richness. A high value of D suggests a stable and ancient site, and a low value of D could suggest pollution, recent colonization or agricultural management. The index is normally used in studies of vegetation but can also be applied to comparisons of animal (or even all species) diversity.

Example: A lake contains 934 brown trout, 733 smallmouth bass, 34 catfish, 2003 carp,

234 steelheads, and 32 northern pikes.

Fish

Number (n)

n(n-1)

Brown Trout

934

934 x (934-1) = 871422

Smallmouth Bass

733

733 x (732) = 536556

Catfish

34

34 x (33) = 1122

Carp

2003

2003 x (2002)=4010006

Steelheads

234

234 x (233)=54522

Northern Pike

32

32 x (31)=992

Total (N)

3970

= 5 474 620

= 3970 x 3969 = 15 756 930

D = = 2.88

Simpson’s Diversity Index – Practice Problems

When comparing two or more samples, the location with the larger D has a greater amount of diversity. Note that a higher total population does not indicate higher diversity.

An area of the Black Forest in Germany contains 134 pitch pines, 24 douglas firs, and 53 red pines.

A meadow contains 1532 chestnut oaks, 342 black cherry trees, 12 white ash trees, and 1022 yellow birches.

Your backyard contains 12 fleas, 34 aphids, 84 ants, 93 beetles, and 1 butterfly.

An African National Park contains 15 lions, 94 giraffes, 1000 wildebeests, 50 elephants, and 5 hyenas.

Mindo (a city in Ecuador) has 832 toucans, 392 red headed barbets, 3 golden headed quetzals, 500 tanagers, 899 parrots, and 50 white capped dippers.

Answer the following questions in your workbook:

Calculate Simpson’s diversity index for each location. Include the table in your workbook.

Distinguish the differences in diversity between two locations listed above.

Explain what may lead to those differences.

Outline the significance of the Simpson’s Diversity Index. You may refer to the following online resource and your textbook to help outline your ideas - http://www.countrysideinfo.co.uk/simpsons.htm

Scientists are uncertain about how life began on Earth.<br>Why?​
Ksju [112]
By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth. There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind. This is why scientists cannot be certain about how life began.

vekshin1
The introduction of the Asian Clam in Lake George is an example of an Invasive Species.

Asian Clam are small in size, hardly 1.5 inches long. However, they can reproduce very quickly without the need for a partner. A single clam can give birth to hundreds of offspring in a single day without a mate.

Asian Clam is extremely unpleasant for most fresh water bodies since it excretes nutrients such as nitrogen.

This helps in the development of algae and gives off a foul stink.

What is the appropriate dose of 1:10,000 (0.1 mg/ml) concentration of epinephrine for endotracheal administration to a baby weig
vlada-n [284]
I believe the appropriate dose will be 1.5 mL, 
Epinephrine is used for both allergic reaction and heart attacks, in an effort to increase blood flow through veins and to reduce swelling in airways. When epinephrine is recognized by receptors on smooth muscles, it causes airway-blocking muscle constriction to subside. Other drugs that may be administered by the endotracheal route include atropine sulfate, lidocaine hydrochloride, naloxone hydrochloride, and metaraminol bitartrate.
