Which personality trait describes the will to keep trying even after failing?

Coat color in cattle is an example of incomplete dominance. When cattle with solid white coats (W) are mated to cattle with soli

Lisa [10]

Answer:

There is a 25% chance for solid white coats.

Explanation:

To check the chances of a solid white coat offspring being formed, lets make a punnet square.

The gametes of the parents will be W and R v/s W and R.

W R

W WW WR

R WR RR

A punnet square is a diagram which is made to test the outcomes of a cross.

As the following punnet square shows:

There is 25% chance for solid white coat offspring to be formed (WW).
There is a 50% chance for the offspring to be roan (WR).
There is a 25% chance for the offspring to have solid red coats (RR).

Which type of solution will cause cells to swell, or even to burst?

Inga [223]

Answer:

(b) Hypotonic solution

Explanation:

Any solution having lower osmotic pressure as compared to another solution is called as a hypotonic solution and the reason that a solution is hypotonic is that it has more water and lesser dissolved solute in it.
If a cell is placed in a hypotonic solution, the amount of water content in the cell would be lesser as compared to that of the solution and hence, the water will enter the cell due to which the cell will swell and may even burst.
The water molecules can enter the cell through the semipermeable membrane and in case of plant cells, the presence of cell wall may prevent it bursting, however, the animal cells lack the cell wall and hence if kept in hypotonic solution for long these cells may burst.

How is the way a dog looks at a face similar to the way humans look at faces

GarryVolchara [31]

Answer:

ever wonder if your dog really really loves you — or if he’s just in it for the kibbles?

Alas, scientists haven’t figured out exactly how our dogs feel about us. But a study published this week in the journal PLOS One has yielded fresh insight into how dogs see us. It adds to existing research showing that — much like humans, other primates and even goats — our canine friends use specific regions of their brain to “process” our faces.

“Our study provides evidence that human faces are truly special for dogs, as it involves particular brain activity,” study co-author Dr. Luis Concha, an associate professor at the National Autonomous University of Mexico’s Institute of Neurobiology, told The Huffington Post in an email. “To dogs, the human face is no ordinary thing.”

What is natural selection? how was it derived from artificial selection?

Yanka [14]

The breeding of plants and animals to produce desirable traits. Organisms with the desired traits, such as size or taste, are artificially mated or cross-pollinated with organisms with similar desired traits.

Now we need to prepare a buffer that has a pH of 7.4. We need this specific pH to

Anestetic [448]

Answer:

b) By mixing weak base with its conjugate acid and then adjusting the pH with strong acid.

Explanation:

Hello,

In this case, considering that the buffer required a pH greater than 7 where the basic conditions are present, we need a weak base and its conjugate base in order to assure such pH greater than 7. Moreover, by using a strong acid, we can gently add it in order to decrease the pH up to 7.4 via a properly measured neutralization of the necessary moles of base up to a hydrogen concentration of 3.98x10⁻⁸ (pH). Therefore, answer is b) By mixing weak base with its conjugate acid and then adjusting the pH with strong acid.

Best regards.
