An investigation was carried out over a five-year period to measure the effect of color on the survival of trout in a stream. The stream contained many brightly colored stones and food was plentiful. At the start of the investigation (year 0), 100 bright-colored trout and 100 drab-colored trout were placed into a section of the stream that had been blocked with netting. Investigators monitored the trout populations for five years and recorded the water condition each time a count was done. The data collected are shown in the table below.
Year Bright colored trought Drab colored trought condition of water
0 100 100 clear
1 64 36 clear
2 86 25 clear
3 25 77 cloudy
4 14 86 cloudy
5 90 9 clear

How does this demonstrate that natural selection depends on the environment? This will be graded based on your overall claim and supporting statements, use of direct evidence from the data table, and your reasoning (CER).

In "simple columnar epithelium," which word describes cell shape and which word describes the number of cell layers?
dolphi86 [110]

Answer:columnar describes cell shape.

Simple describe the number of layers

Explanation: epithelial tissues are one of the four major tissues of the body.the others being nervous, muscular, connective tissues.

Epithelial tissues are made up of thin cells that cover the external and internal surface of the body.

The cells may form one layer or more and they occur in several shapes.if they form one layer ,it is called simple.if they form several layers,it is called stratified.

Some are called pseudo-stratified because the cells occur with varying lengths and give the impression of stratified but they are actually made up of one layer.

Simple columnar epithelium is a single layer of tall, closely packed cells. They possess cellular extensions ,such as microvilli in the small intestine, or the cilia in the female reproductive tract.

Lithified ash (or ash mixed with pyroclastic fragments) forms a volcaniclastic rock called a:________
sweet [91]

Lithified ash (or ash mixed with pyroclastic fragments) forms a volcaniclastic rock called a Tuff.

  • A form of rock called tuff is created when volcanic ash is blasted from a vent during an eruption.
  • The ash is transformed into a rock after ejection and deposition. Tuff is defined as rock with an ash content of more than 75%, whereas tuffaceous refers to rock with an ash content of 25% to 75%.
  • The thickness of tuff often decreases with distance from the volcano and is usually greatest close to the volcanic vent. The typical shape of a tuff deposit is that of a "lens," not a "layer."
  • Tuff may also be thickest on the vent's side that faces away from the wind or on the side facing the direction of the blast.
