Answer:

20%

Explanation:

The frequency is the number of times a given thing appears in a specific period of time.

In the given situation, you have a total of 80 cows, amongst these 16 have black and white coat and 64 have solid black coats.

To find the frequency of black and white coats you need to simply find it probability.

This would be = No. of cows with black and white coats/ total number of cows

using this formula we get => 16/80 = 2/10

Therefore frequency in terms of percentage would be 2/10 X 100 = 20%.

There are 6 molecules of O2.



"O2" is the formula for one molecule oxygen, which has 2 atoms.

The subscript (small) "2" tells you how many atoms are in the molecule.

The coefficient is the big number tells you the number of molecules.

In 6O2, there are 12 atoms in total (6 molecules of 2 atoms each).

what types of minerals are good conductors of electricity, are strong and can be formed into various shaped and sized products w
Sidana [21]

Minerals which are good conductors of electricity are described below.

Explanation:

  • metals tend to be highly efficient conductors of heat and electricity. The vast majority of elements on the periodic table are metals, and most of these fall into one of five families: alkali metals; alkaline earth metals; the very large transition metals family; and the inner transition metal families, known as the lanthanides and actinides.
  • Metals are lustrous or shiny in appearance, and malleable or ductile, meaning that they can be molded into different shapes without breaking. Despite their ductility, metals are extremely durable and have high melting and boiling points. They are excellent conductors of heat and electricity, and tend to form positive ions by losing electrons.

Alex777 [14]

Answer:

Reinforcement

Explanation:

Reinforcement can be referred to as anything that can be used to increase, enhance or strengthen a desirable behavior in a person or an organism. Reinforcement is of two types, they include positive reinforcement and negative reinforcement. Positive reinforcement has to do with adding a reward in order to enhance a desirable behavior, while negative reinforcement has to do with removing an undesirable thing in order to strengthen a desirable behavior.

From the question asked,  because the presence of insects after moving the decaying logs increased the frequency at which the bears moved the decaying logs, the finding of the insects is, therefore, a reinforcement. The finding of the enhanced or strengthened the desirable behavior.
