Answer:

Cl_3Al

Explanation:

* = electron

Cl (17) * * * * * * *

Al (13) * * *

If one of aluminum's electrons were added to chlorine to make a full shell, still have 2 left over. So you need another:

Cl * * * * * * * * (full)

Cl * * * * * * *

Al * *

Still have another left over. Aluminum needs to lose another one of its valence electrons to be able to have a full shell. So you take another chlorine:

Cl * * * * * * * * (full)

Cl * * * * * * * * (full)

Cl * * * * * * *

Al *

You will eventuate with 3Cl and 1Al, or Cl_3Al. Modeled above:

olga_2 [115]

Answer:

C.)organs are a group of two or more different types of tissues that work together to perform a specific function

Explanation:

Cells of similar function are grouped together into tissues. For example, cardiac muscle tissue is present only in the heart, and made up of specialised cells called cardiomyocytes, or cardiac muscle cells. These cells contract to pump blood around the body.

The heart is an organ, consisting of multiple types of tissue including cardiac muscle tissue, connective tissue, blood vessels and epithelial tissue. Therefore, organs represent a group of at least two types of tissue that work together to carry out functions in the body.

Explain the difference between personal opinion/interpretation and verified observations
LuckyWell [14K]

Answer:

Explanation:

Personal opinion/interpretation are usually firsthand explanation to a phenomenon or problem set. They are usually drawn from logical reasoning and deduction about some event. Most times, they are non-scientific in nature in that they are non-methodical and do not rely on the critical thinking precepts scientific studies are hinged on.

Verified observations are usually drawn from carefully planned experiments. From the results of the experiment, critical decisions can be made.
