Answer: The correct answer is- B) AA.

Dominant allele is the one that masks the expression of recessive allele and is depicted by capital letter. Homozygous dominant genotype means both the alleles ( alternative form of a gene) are same.

Out of the given options, option B) AA shows that both the alleles are same and are dominant.

Thus, B) is the right answer.

It is not always possible to measure every individual in a population; what is the name of the representative group?
ra1l [238]

Answer:

d. sampling unit

Explanation:

<u>Sampling unit:</u>

Refers to the unit or group of elements that are selected from an original population during an investigation. The sampling unit might be composed of a statistical unit or a group of statistical units.

The statistical unit or element is the elemental unit that composes the target population.

The sampling unit is a basic concept to keep present during the development of the investigation project. It is the minimal unit of observation that will be used to take information about the variables of interest.  All the sample unit composes the population and is defined by an <em>N</em>, while only some representative sample units compose the sample, and are represented with an <em>n</em>.

So, the whole population can not be measured because of its size, or the individuals´ characteristics, among other many factors. So we need to take a random and representative sample or group of the population to proceed with our investigation. This sample or group is composed of some of the original population individuals, which are defined as "sample units".

A usable dilution of disinfectant is one that prevents growth of bacteria when compared with the positive control tube. reduces
dolphi86 [110]

When compared to the positive control, a disinfectant dilution is considered to be useful if it stops bacterial growth.

Choosing a disinfectant:

When selecting a disinfectant, keep the following things in mind:

  • The range of bacteria that need to be eliminated. Look into the specifications of the manufacturers.
  • The conditions of usage of disinfectant.

Application of disinfectants :

  • Activity: it is necessary for efficient disinfection since, once diluted, it degrades over time. Different disinfectants deteriorate at different rates. Obtain data from the manufacturers. Disinfectants that don't have a color indication, like Virkon, should be marked with an expiration date.
  • Touch time: it has to be verified that the manufacturer's data to make sure the organism stays in contact for the specified amount of time. Considering that solid materials like cells and tissue granules are difficult for disinfectants to penetrate, autoclaving would be a more effective way to inactivate.

Therefore the correct choice is an option (A).

Calcium has an atomic number of 20 and an atomic mass (weight) of 40. Therefore, we know that calcium has
romanna [79]
It would have 20 protons, 20 neutrons, and 20 electrons. Protons and electrons are USUALLY (I say usually because of the different types of atoms) the same as the atomic number. To find neutrons you take the atomic mass minus the atomic number. 40-20=20
