4. Describe an observation you made today and an inference you can make from that observation.
OleMash [197]

Answer:

my my teacher gives my class and I a mystery box for us to observe what's inside that box it was closed, as we was trying to know what's inside that box we were looking and thinking what does it sounds like, but my friend next to me says it sounds like a stapler and my other friend said it's not very heavy, as we were we said we could take another box just like that identified box and put a stapler since it sounds like a stapler and it's not that heavy as we know staplers are not that heavy. well we did that we check and our activity shows that the mystery box it slides and appear to be flat and all the box it slides in appear to be flat so that's the same thing as our box and the mystery box and we were looking at how does it sound when we close the box and everything we were checking how does it sound as we are observed that the mystery box it makes a metallic song when it strikes the side of the box an hour box the stapler makes a thudding sound when it strikes the side of the box and we also checked if the mass of the box was the same but it wasn't the mystery box was 270 g and our box was much more heavier which is 410 g so we were checking what was the really wrong thing we was checking and checking is like what should we do next, and we did in for the things in the box had to be different because our observation of the two boxes are different, and we observed yes things are different of course.

and there's a picture with the observation chart I will be showing it's above take a look and you will be have more understanding and knowledge about the really topic I am talking about thank you.

kotykmax [81]

Traditional classification is based on superficial attributes of organisms while modern classification is all-encompassing.

<h3>Traditional versus modern classification</h3>

Classification refers to the science of grouping living organisms based on certain attributes.

Traditional classification groups organisms based on superficial attributes such as similarity in appearance, habitats, etc.

Modern classification takes cognizance of virtually all the attributes of organisms, including evolutionary relationships, biochemical similarity, etc.

Based on the information in the chart, during which eon would you expect to find fossil evidence about the evolution of insects?
Ivahew [28]

Answer:

A) Phanerozoic

Explanation:

In the given question, the chart about the evolution of insects has not been provided but based on the previous knowledge, this question can be answered.

The geologists have divided the time scale into many variables in which Eon represent the longest time scale period which has lasted for the millions of year.

The Phanerozoic eon represents the time scale during which first visible life evolved and began around 542 million years ago and is present until today. The insects belong to the arthropod group which evolved during a smaller time scale called Devonian period.

Since the insects evolved around 479 million years ago which falls under the Phanerozoic eon, therefore, phanerozoic is the correct answer.

Thus, Option-A is correct.
