A batsman is unlikely to score a century in every cricket match. This is an example of "partial reinforcement".

Option: C

Explanation:

Unlike constant reinforcement, partial reinforcement is only strengthened during certain times or time ratios, rather than emphasizing the action every single time. This method of arranging reinforcement is also called intermittent reinforcement after certain number of correct answers or certain interval of time. Thus here a batsman donot plan intentionally to make a century in every cricket match, but it goes random. Although when they need to score high on pressure, they force themselves to stretch as much possible which is not general.

What is the best description of what viruses are made of?

Mazyrski [523]

The answer is C.

A virus is made up of or consists of a nucleic acid in varying quantity which may either be RNA or DNA.

The nucleic acid is surrounded by a protein shell called a capsid. The word capsid comes from the Latin word capsa which means box.The capsid and the nucleic acid within it are together referred to as nucleoprotein.The capsid is made up of small sub units called capsomeres.

In many viruses, the nucleoprotein makes up the whole virus. More complex viruses have one or more further enclosing structures also made mostly of protein. These structures are referred to as envelopes and each envelop is specific to a particular virus.

uysha [10]

Answer:

C. An approximately three-to-one ratio of black to brown coated mice in F2 is accounted for by the black allele being dominant over the brown allele

Explanation:

Assuming the black genotype is BB and the brown genotype is bb.

At F1:

BB x bb = All Bb (black)

At F2:

Bb x Bb = BB (black), 2Bb (Black), bb (brown)

Th ratio of black to brown is 3:1

961 black : 317 brown is approximately 3:1.

Hence, the correct option is C.

An approximately three-to-one ratio of black to brown coated mice in F2 is accounted for by the black allele being dominant over the brown allele

Why might it be more difficult to prepare a vaccine against noroviruses than against rotaviruses?

White raven [17]

Designing efficacious norovirus vaccines remains a major challenge due to several factors:

(1) the extreme genetic variability within the norovirus family and within genogroups

(2) the rapid evolution of antigenically dissimilar pandemic GII.4 norovirus strains

(3) the lack of lasting immunity upon natural exposure to noroviruses in at least a proportion of the population.
