Describe how epinephrine has different effects in different target tissues
Answer:
Epinephrine binds to receptors on some smooth muscles (ex: around arterioles) → Ca++ released from ER → intracellular Ca++ up → stimulates contraction. c. Epinephrine binds to receptors on some smooth muscles (ex: around bronchioles) → phosphorylates protein needed for response to Ca++, preventing response.

<< Previous Question
Next Question >>
Answer:
C!!
Explanation:
It's not B because it's located in the great plains. Not D because in 50 years, 70% of the aquifer will be gone. Not A because water use isn't regulated.
Ogallala Aquifer is the rock holding the groundwater in the Great Plains of America. The Ogallala Aquifer is running out of water. Thus, option C is correct.
What is Ogallala Aquifer?Ogallala Aquifer is an underground layer of water that is held by the rocks, pebbles, and gravel that make the water well above the surface. It is not beneath the East Coast but is situated on the Great Plains of the United States.
It has been reported that the water usage of the Ogallala Aquifer is not regulated and hence it does not have enough water to last up to 6,000 years. At approx 70%, the water of the aquifer will be soon gone resulting in the deprivation of the water.
Therefore, option C. the Ogallala Aquifer is running out of water is correct.

Where do the thickest deposits of terrigenous sediment typically form?
A. deep-ocean trenches, such as the Mariana Trench
B. mid-ocean ridges
C. abyssal plains
D. continental margins near the mouths of rivers
Answer: D. continental margins near the mouths of rivers
Explanation:
Terrigenous sediments are those that are formed via processes on land as opposed to in water. They result mostly from the erosion of rocks and yet make up 20% of all ocean sediments.
Continental margins near the mouths of rivers contain the thickest deposits of this sediments as they are closest to land which is the source. It is made more convenient by the presence of rivers bringing the sediments to them when the rocks are eroded.
What is meant by the term "density"? Please provide an example of how
density is determined in air masses.
Answer:
1) density "the degree of compactness of a substance."
2) air masses "More dense, or “heavier” air will slow down objects moving through it more because the object has to, in effect, shove aside more or heavier molecules. Such air resistance is called “drag,” which increases with air density."

A scientist is researching two different traits in an insect: body texture and color. Smooth body (B) is dominant to bumpy body (b), and gray (G) is dominant to white (g). A BbGg and a bbgg insect mate and produce the following 480 offspring: Phenotype Number of Offspring Smooth, gray 119 Bumpy, white 117 Smooth, white 123 Bumpy, gray 121 What type of inheritance is displayed from these offspring
Answer:
Independent assortment
Explanation:
The type of inheritance displayed by the offspring is a simple independent assortment inheritance according to Mendelian law.
The result of crossing BbGg and bbgg is as follows (see the attached image)
4 BbGg smooth and gray
4 Bbgg smooth and white
4 bbGg bumpy and gray
4 bbgg bumpy and white
The phenotype ratio from the cross is 1:1:1:1 as far as the independent assortment is concerned.
Now, looking at the population of each phenotype from the cross
Smooth, gray 119
Smooth, white 123
Bumpy, gray 121
Bumpy, white 117
119:123:121:117 is approximately equal to 1:1:1:1.
Hence, the cross agrees with Mendel's law of independent assortment of genes.
