(a) Predict what would happen if, after 22 months, guppies from the transplanted population were returned to the source pool. (b) Describe an experiment to test your prediction.

Answers

Based in the experiment with the guppies, it can be concluded that natural selection is a factor of evolution.

What is a hypothesis?

A hypothesis is an explanation put forward to explain an observation without prior testing.

From the observations in the guppies;

The question is whether natural selection is favors coloration in guppiesThe hypothesis is that natural selection determines coloration in guppies The prediction is that guppies with bright coloration will thrive in a predator free environment The control group is the source poolthe experimental group is the transfer poolthe conclusion from the data is that guppies with bright coloration are naturally selectedReturning the guppies from the transfer pool to the source pool will essentially reduce the population of the bright colored guppies due to predation.

Therefore, it can be seen from the guppies that natural selection drives evolution of species.

An amoeba is a single-celled organism. Amoebas extend their cell membrane around a food particle or prey organism. Then, the bring the food into the cell, as shown in the picture. Which term best describes the cell process amoebas use to get food *

A.exocytosis

B.endocytosis

Answers

Answer:

endocytosis

Explanation:

Endocytosis is a cellular process in which substances are brought into the cell. The material to be internalized is surrounded by an area of cell membrane, which then buds off inside the cell to form a vesicle containing the ingested material.

An amoeba is a single-celled organism that extend their cell membrane around a food particle or prey organism, and the term that best describes the cell process amoebas use to get food is called endocytosis, which is in option B.

What is the significance of endocytosis?

Endocytosis is seen in both the cells of the unicellular eukaryotes and the multicellular cells and by this process, the cells take the food in and use it for many processes, such as in the amoeba, which takes the food in and later uses it for the cellular process. The water intake is seen by the cells and called "pinocytosis," while the removal of the product from the cell is called "exocytosis."

Hence, an amoeba is a single-celled organism that extend their cell membrane around a food particle or prey organism, and the term that best describes the cell process amoebas use to get food is called endocytosis, which is in option B.

#CarryOnLearning

Answer:

1. (A) Sea Breeze

2. (C) Uneven heating of earth'S surface

3. (C) Mountain Breeze

Explanation:

Sea breezes occur during hot, summer days because of the unequal heating rates of land and water. During the day, the land surface heats up faster than the water.Local winds are caused by unequal heating of Earth's surface within a small area. Local winds form only when large-scale winds are weak. A sea breeze is a local wind that blows from an ocean or a lakeWhen the valley floor warms during the day, warm air rises up the slopes of surrounding mountains and hills to create a valley breeze. At night, denser cool air slides down the slopes to settle in the valley, producing a mountain breeze.

11.) If a hypotonic solution surrounds a cell; water will ___.

b.) be transported by proteins in the plasma membrane
c.) move out of the cell
d.) move into the cell
e.) be dissolved

Answers

Answer: The cell will swell

That’s from what I can remember, I hope I helped out a little

Solutions are categorized as isotonic, hypertonic, and hypotonic based on concentration. If a hypotonic solution surrounds a cell; water will move into the cell. Thus, option d is correct.

What is a hypotonic solution?

A hypotonic solution has been defined as a solution that has been known to have a lesser amount of the concentration of the solute dissolved in the solvent. The movement of the ions in a hypotonic solution has been regulated by the osmotic pressure.

Osmosis moves the ions from the concentration from an area with low solutes to the area with higher solute concentration. When hypotonic solution is present outside the cell then the ions move inside the cell resulting in swelling of the cell.

Therefore, option d. in hypotonic solution solute moves inside the cell.
