Answer:

Controlled Investigation

Field Investigation

Explanation: In a controlled experiment, the scientist has total control over the environmental conditions.  The temperature, humidity, amount of light, amount of noise, materials, etc. can all be controlled and monitored by the scientist throughout the investigation.

A field investigation involves observing and measuring plants and animals (including people) in their natural habitat or environment without changing, harming, or altering the setting or any part of the test subjects.  Like in a controlled experiment, the scientist chooses to observe and measure how one change (IV) has a measurable effect (DV) on something else.

What is one change that would cause more water to evaporate from a stream?
Svetllana [295]

Evaporation

Explanation:

Evaporation is one change that would cause more water to evaporate from a stream.

Evaporation is a phase change in which liquid is changed into its gaseous form.

  • When a substance is heated from solid to liquid, it melts.
  • After melting, additional heat causes a phase change that allows for the liquid to change to gases.
  • In the water cycle, the sun provides heat energy that causes surface water in streams to be heated.
  • This leads to evaporation of the surface water into the atmosphere where they can be condensed to form precipitation.

In the endoplasmic reticulum were removed from the cell which organelle would not be able to function properly and why
zalisa [80]
No endoplasmic reticulum (ER) would result in the cell's death.

There are two types of ER, rough and smooth.

Rough ER (RER) is studded with ribosomes and this is the site of protein synthesis. The RER is very important for proteins that are to be secreted - these proteins have a signal peptide (the first 5-10 amino acids) that gets processed inside the ER lumen - a signal peptidase removes the signal peptide and then this goes to the Golgi to be delivered. No RER - no proteins get secreted to the cell wall - so no transporters, etc. Not a happy cell.

The smooth ER functions in lipid biosynthesis and metabolism. It is also the site of steroid hormone production and detoxification. It is also the site of the initial glycosylation of proteins. If this doesn't happen, the protein doesn't function properly.

No ER = bad news for a eukaryotic cell!

A simple change in DNA results in
Gekata [30.6K]
I believe a simple change in DNA results in Mutation. A mutation is a random spontaneous changes that occur in the genetic make up of an organism ( in the DNA sequences). The mutation are either due to mistakes when DNA are being copied or as a result of environmental factors such as UV light and cigarette smokes among other mutagens. Mutations may be either gene mutation (permanent alteration in the DNA sequence that makes up a  gene) or chromosomal mutation.
