Section 1

00:00:00

TEACHER: No, this is my banana. You already had a banana. You're not getting another one. Just hang out for a second. I got some students to teach. All right, take a look at this monkey here. You know this cute little guy as an animal.

00:00:12

But how do you really know it's an animal? What characteristics make it an animal but not the tree that it's hanging on? Well, that's what we're going to talk about in this lesson as we work to answer the lesson question which is-- how are animals distinguished from other living things? In a moment, we'll take a look at your lesson goals but I'm going to eat this banana first.

Section 2

00:00:00

TEACHER: Before beginning any lesson, it's important to take a look at your lesson goals because it gets your mind thinking about what you're going to be learning. As we explore the animal kingdom, we are going to examine the characteristics that are common to most animals. We'll identify the main functions

00:00:15

that allow animals to meet their basic needs. And we'll compare and contrast the characteristics of invertebrate and vertebrate animals. Now look at the screen here. There are a lot of words for you to know. We have asymmetry, bilateral symmetry, heterotroph, invertebrate, radial symmetry, vertebrae, and vertebrate. Now again, these are all important science words so now

00:00:41

would be a great time to hit that pause button on your computer, tablet, phone-- whatever you're using-- and write these words down. Even go ahead and take a look at their definitions in your glossary because I'm about to start the lesson right about now. I would like to begin by talking to you about the classification of living things.

00:01:01

And you might recall that there are three domains of life. There's bacteria, archaea, and eukarya. The bacteria and archaea domains both contain prokaryotes, which are organisms whose cells lack nuclei. So let me write prokaryotes here. There we go. Also, keep in mind that these two domains,

00:01:28

they differ in structure and chemical makeup. And then we have the domain eukarya. The domain eukarya contains organisms whose cells contain nuclei. Therefore, these organisms are eukaryotes. And I'm going to write eukaryotes here. Aha.

00:01:51

Also, this domain is divided into four kingdoms that include protists-- let me put a 1 here-- plants, fungi, and, finally, animals. In this lesson, we're going to talk about the animal kingdom. Well, the name of the kingdom is actually animalia, which is where the word animal comes from.

Answer:

No, it is not a square

Step-by-step explanation:

If one wall is 19", that would mean the wall perpendicular to this wall is also 19" (in fact all of the walls would be 19"!) If this was a square, then the diagonal we draw at 20.62" would serve as the hypotenuse of a right triangle. One wall would serve as a leg, and another wall as another leg. If this is a square, then the Pythagorean's Theorem would be satisfied when we plug in the 2 wall measures for a and b, and the diagonal for c:

$19^2+19^2=20.62^2$

We need to see if this is a true statement. If the left side equals the right side, then the 2 legs of the right triangle are the same length, and the room, then is a square.

361 + 361 = 425.1844

Is this true? Does 722 = 425.1844? Definitely not. That means that the room is not a square.

Answer:

The area and the perimeter of the picture are:

Area = 160 cm^2
Perimeter = 67.31 cm

Step-by-step explanation:

To find the area of that figure, you can find the area how if it was a rectangle and next subtract the area of the triangle in the upper part. The area of a rectangle could be found by the next formula:

Area of a rectangle = base * height

As you can see in the picture, the base is 16 cm and the height is 12 cm, then we replace in the formula:

Area of a rectangle = 16 cm * 12 cm
Area of a rectangle = 192 cm^2

Now, we calculate the area of the triangle to subtract to the area we found and obtain the real area, the formula to obtain the area of a triangle is:

Area of a triangle = (base * height) / 2

The height of the triangle is 8 cm, and the base is 8 cm too, because you subtract to the base of the rectangle (16 cm) the measurements in the upper part (16 - 4 - 4 = 8), Now, we replace in the formula:

Area of a triangle = (8 cm * 8 cm) / 2
Area of a triangle = (64 cm^2) / 2
Area of a triangle = 32 cm^2

We subtract to the found area:

Area of the picture = 192 cm^2 - 32 cm^2
Area of the picture = 160 cm^2

To find the perimeter, you must add all the sides of the picture, but, as you can see, there is a side that doesn't have the measurent, this is the hypotenuse of the triangle used before, but how we know the other sides, we can use Pythagorean theorem:
