Answer:
c. 10
Explanation:
The pH scale ranges from 0 to 14.
0 is the most acidic
7 is neutral
14 is the most alkaline
10 is near 14
Osmosis is the movement of <em>water </em>from a region of higher water concentration to a region of lower water concentration across a selectively permeable membrane. Simply put, water passes across membranes into areas where more 'stuff' is dissolved.
In this system, The slice shriveled in salt solution. That means water left the potato's cells. Then the slice regained its shape when placed in pure water. That means water moved back into the cell.
A) <em>incorrect</em>. Salt does not move across the membrane
B) <em>incorrect</em>. If water moved into the slice, it would have swelled, not shriveled
C) correct. Water moved out of the cell into the more concentrated salt solution
D)<em>incorrect</em>. Placing the slice in pure water does not balance the concentration of salt between the cells and the water.<em />
Answer:
I<em> think</em> it's only one allele is required to express the trait.

Answer:
Because the west coast has winds blowing off the water (because of the earths rotation and the prevailing westerlies). The waters along the west coast are much cooler than the east coast during the summer so if the winds blew off the east coast, a lot of the eastern US would be pretty tropical. NYC wouldnt even see snow to give you an idea. I would guess that day time highs in the WINTER in virginia beach would be in the upper 60s with nights in the low to mid 40s if winds blew off the east coast and summers would be cooler with daytime highs getting in the low to mid 80s and lows in the low 70s. Much milder during the winter and in the summer which means warmer winter temps and slightly cooler summer temps also. NYC would probably have a January high temperature in the upper 50s and a low temperature in the upper 30s to low 40s and a July high temperature in the mid 80s with a low temperature in the low 70s.
I just came up with those temperatures in my head, but the point is that the water does moderate temperatures a lot and even though the waters in the west coast are much cooler than the east coast (ex is san diego with a water temp in the low 60s and NYC with a water temperature in the upper 70s this time of the year) but since the wind blows off the water on the west coast and the mountains block inland winds, the west coast is milder than the east coast.
Explanation:
The gene which is produced once or twice in a lifetime is the milk producing hormone after childbirth. This is because it is produced only after the birth of the child. The growth of the mammary glands takes place during pregnancy. The breast continue to increase in size after giving birth to a child. After delivery only copious milk is produced which is generally done with the help of milk hormone. During pregnancy the secretion of the milk is inhibited by the estrogen and progesterone which circulates in the blood stream which in turn inhibits the release of prolactin from the pituitary gland thus making the mammary glands unresponsive. Where as insulin is a hormone which helps the body to utilise the sugar or glucose from different sources like carbohydrates that we get while we eat food and adrenaline is secreted when we are scared or when we feel that we are in danger. Therefore, milk producing hormone is the gene that are turned once or twice in a lifetime.
