Garrett notices a small island has formed off the coast of his hometown in Florida. Which of the following best describes what c

aused the island to form?
The sand was deposited into a pile by the action of waves.
Beach sand that was eroded from the local beach formed an island.
The sand was a remnant from a tropical storm that had a large storm surge.
Erosion of the areas behind the island caused it to be surrounded by water.

I would say either the first, second, or fourth answer; waves have a very strong impact on the movement of sand and other particles under the water. Erosion of particles off an island are similar in this case.
It wouldn't be anything about a tropical storm; it's no where in the question and we don't know how many storms Florida has or how strong they are.

Why is the resting membrane potential (Vm) approximately - 70 mV for most cells? Most cells contain a large concentration of Cl-
Yuki888 [10]

Answer:

Option (4).

Explanation:

Cell membrane potential may be defined as the difference in the electric potential between inside and outside of the cell. This potential is important for the action potential.

The resting membrane potential of the cell is -70mV. This membrane potential is maintained by the potassium ions of the cell. The cell membrane are almost 40 times more permeable to potassium ions than sodium ions and makes the cell membrane potential negative.

Thus, the correct answer is option (4).

Predict what the calf produced in a union between each of these parents might look like. Explain your answers.
Charra [1.4K]
We know that purebred means that the organism contains the same alleles for the trait and hybrid means that it contains two different alleles for the trait. Dominant means that it will be shown in a hybrid and a purebred, but recessive traits will only be shown in purebred recessive organisms.

a) The offspring of a purebred white (recessive) cow and a purebred brown (dominant) bull, would be all hybrid brown (dominant). This is because as I stated above, dominant traits are shown when the offspring has both dominant and recessive alleles for the same trait.

b) The offspring of a purebred brown (dominant) cow and a purebred brown (dominant) bull would all be purebred brown (dominant). This is because if both of the parents have only alleles that code for brown color, the only color that the offspring can be is brown.

c) The offspring of a purebred white (recessive) cow and a purebred white (recessive ) bull would all be purebred white (recessive), for the same reason stated above in part b), the only difference being that the alleles are recessive and code for white color instead of being dominant and coding for brown color.

d) The offspring of a hybrid brown (dominant) cow and a purebred white (recessive) bull would be half hybrid brown (dominant) and half purebred white (recessive). This can be seen best if you set up a Punnett Square, which is a diagram that shows allele frequencies in offspring. This shows you that the chance that the offspring get the dominant allele from the mother cow is 50%, thus 50% would be hybrid brown (dominant), as the father can contribute only a recessive white allele. The other 50% would be purebred white (recessive) because the mother cow would be contributing a white allele and so would the father.

Hope this helps! :)

If cells are placed in a hypertonic solution containing a solute to which the membrane is impermeable, what could happen?
finlep [7]

Answer: A

 The cells would lose water and shrink. In a hypertonic solution, the concentration of solute is higher than water in a cell. With this, there is a net movement of water from inside to outside initiating water to lose from the cytoplasm and vacuole causing the cell to shrink due to osmosis and achieve equilibrium.

This process is applied in food preservation where microbial cells will be dehydrated in a hypertonic environment, making them malfunction and preventing them to cause food spoilage.
