Students used gummy bears to represent cells in the gummy bear osmosis lab. After obtaining an initial mass for each gummy bear,

the gummies were soaked for 24 hours in different solutions and then dried and massed. The solutions included: distilled water, tap water, 20% sugar solution, and 40% salt solution. After 24 hours, the percent change of each gummy bear was calculated and is shown below:
Distilled Water: +320%
Tap Water: +200%
40% Salt Solution: -60%
20% Sugar Solution: +85%

Based on the data, which gummy bear was in the salt solution and what was the tonicity of that solution?
A) A; hypotonic
B) D; hypotonic
Eliminate
C) B; hypertonic
D) C; hypertonic

Group the terms according to the subatomic particle they describe.
LiRa [457]

Answer:

This question is incomplete

Explanation:

This question is incomplete but the completed question can be seen in the document attached.

There are three main subatomic particles namely electrons, protons and neutrons. However, the question only discusses two of them; electrons (negatively charged) and protons (positively charged).

A. Found in all matter

Answer: They are <u>both</u> found in all matter since all matter are made up of atoms and all atoms have both protons and electrons (and even neutrons).

B. Negative charge

Answer: The subatomic particle with negative charge (as discovered by R.A Millikan) is the <u>electron</u>

C. Exists in the nucleus

The subatomic particles found in the nucleus are the <u>protons</u> and neutrons.

D. Attract opposite charges

They <u>both</u> (protons and electrons) attract opposite charges because they are of opposite charges and generally unlike charges attract.

E. Moves at extreme speed

Of the two subatomic particles mentioned, <u>electrons</u> move faster than protons because of there lighter mass when compared to the protons. However, the fastest subatomic particle is the neutrino.

F. Bound by strong force

The <u>protons</u> are bound by strong nuclear force which binds them to the nucleus of the atom.

If you think of the earthworm body plan as a drinking straw within a pipe, where would you expect to find most of the tissues th
Otrada [13]

Option (A) lining the straw is correct.

<h3>What is the anatomy of Earthworm?</h3>
  • An earthworm is a terrestrial invertebrate and a member of the phylum Annelida.
  • They have a tube-within-a-tube body structure, corresponding external and internal segmentation, and typically include setae on each segment.
  • They can be found wherever the soil, water, and temperature permit.
  • The body of an earthworm is composed of a digestive tube and a thick cylindrical muscular tube that forms the body.
  • The body is divided into segments, and furrows on the surface of the body serve as markers for the segment boundaries.
  • The top of the first segment, which encloses the mouth, is a lobe made of muscle and flesh.
