Why is blood typing considered codominance and multiple alleles
Alecsey [184]

Answer:

An example of multiple alleles is the ABO blood-type system in humans. In this case, the IA and IB alleles are codominant with each other and are both dominant over the i allele. Although there are three alleles present in a population, each individual only gets two of the alleles from their parents.

Select the correct hybridization for the central atom based on the electron geometry cocl2 (carbon is the central atom).
Rainbow [258]
In this compound (Phosgene) the central atom (carbon is Sp² Hybridized).

Sp, Sp² and Sp³ can be calculated very simply by doing three steps, 

Step 1:
           Assume triple bond and double bond as one bond and assign s or p to it. In this example carbon double bond oxygen is considered once and let suppose it is s. Now we are having our s.

Step 2:
          Count lone pair of electron, each lone pair counts for s and p. In this case there is no lone pair of electron on carbon, so not included.

Step 3:
          Count single bonds for s and p. As we have already assigned s to the double bond, now one p for one single bond, and other p for the other single bond.

Result:
          So, we counted 1 s for double bond, 1 p for one single and other p for second single bond. As a whole we got,

                                                       Sp²

Practice:
You can practice for hybridization of Oxygen in this molecule. Oxygen has 2 lone pair of electrons. (Hint: Sp² Hybridization)

The thickness of a 6.00 cm square piece of Al that has a mass of .842 g and a density of 2.70 g/cm^3
lutik1710 [3]
Volume = Mass / Density
Volume =  .842 / 2.70
Volume = .31185 cubic centimeters
Aluminum square * depth = .31185 cubic centimeters
6 * 6 * depth = .31185 cubic centimeters
depth = (.31185 cubic centimeters) / 36
<span><span><span>depth = 0.0086625514 centimeters

(That must be aluminum foil.)

PLEASE ANSWER BEFORE JAN 1, 2020!!!
True [87]

Answer: option C - The cells produced at the end of meiosis contain half the number of chromosomes as the parent cell

Explanation:

Meiosis is also known as REDUCTIVE DIVISION, simply because a parent cell with diploid number of chromosome (46) is divided into four daughter cells with haploid number of chromosome (23)

Thus, ONLY option C correctly defines meiosis
