one of the tallest dog breeds is the great dane which stands over a meter tall. one of the shortest is the pomeranian which stan

Gemiola [76]

We know that domestic dogs are descended from wolves. Exactly when and how this occurred is still being studied; many experts indicate that dogs were first domesticated about 12,000 years ago, but a few DNA studies indicate a much earlier date for the split between the wolf and the dog, perhaps as long ago as 130,000 years. Regardless of the exact timing of the divergence between wolves and dogs, one thing is true: both species display quite a bit of genetic diversity, particularly in size and coloration.In order to breed a dog of a specific size, all one has to do is choose parents with the appropriate variations. For instance, if you want to create a small dog breed, you would just breed the smallest dogs you have, then you would choose their smallest offspring to breed the next generation, and so on until you have reached the desired size.

A lab director asks two students, Lydia and Damien, to each select a bottle of a concentrated weak base. When they reach the cab

algol13

Lydia and Damien should select the bottle of weak base with high molarity(M)

<h3>Further explanation</h3>

According to Arrhenius, Base is a compound which in water releases OH- ions

Electrolytes (acids or bases) with a small degree of ionization are classified as weak electrolytes

If two students, Lydia and Damien, select each bottle of a concentrated weak base, then a guide can be chosen to choose some of the solutions available in the lab :

Base compounds are usually known from their names ending in hydroxide suffixes such as NaOH, sodium hydroxide

The weak base will be partially ionized in water because the ionization degree is close to 0 or less than 1

If there is a Kb value (base ionization constant), then this shows the strength of the base. The greater the value of Kb, the greater the base strength

If there are some weak bases, then Lydia and Damien choose the highest concentration, usually indicated by the value of Molarity (M)

Because no choice solution is included, the weak base example is:

Ammonia (NH₃)

Aluminum hydroxide (Al (OH)₃)

Copper (II) hydroxide Cu (OH)₂

Mercury (II) hydroxide Hg (OH)₂
