Science-Grade 7 Notes Lesson 2

Chapter 11 Lesson 2

1. Xylem-the tissue that is made up of tubular vessels that transport water and minerals up from the roots throughout the plant.
2. Phloem-a plant tissue that is made up of tubular cells.
3. Cambium-a tissue that produces new xylem and phloem cells.
4. Stomata-the adaption of leaves is small pores in the leaf surfaces.
5. Guard cells-the stomata that open and closes the pores.

Note

• Roots absorb water and minerals, store food and anchor the plant.
• Stems transport the food and water between roots and leaves to support the plant.
• The palisade layer of leaves carries out photosynthesis. Xylem and phloem tissues are located in the spongy layer of the leaf.
• Roots have vascular tissue to move water and minerals from the ground up through the stems to the leaves.
• Each root system must support the plant parts that are above the ground-the stem, branches, and leaves of the tree, for example.
• Roots also store food. When you eat carrots or beets, you eat roots made up of stored food.
• The main functions of a stem are to support the plant and to allow movement of materials between leaves and roots. Some stems also allow them to store food.
• Inside a leaf, a leaf has many different layers, it has a rows of closely packed cells just below the upper epidermis. Palisade cells and the lower epidermis is a layer of loosely arranged cells, the spongy layer, and many air spaces. Xylem and Phloem are located in these air spaces.

Grade 6-How to Correctly Find the Surface Area

Math- Surface Area and How to Find Them

As you know on the previous homework, you may not have understood it correctly. This would help you on the next homework about surface area.

Surface area is the area of the surface of a 3D figure. Surface area can be calculated by bring the shape to be transparent. This would help you note which side of the shape you did. For example, if you would be calculating the surface area of a rectangle, you would make it transparent. Then calculate the surface area. Then add. To find the surface area, you will have to make each side of the transparent figure look like a 2D figure.

This figure shows a transparent figure.

When you are writing your equations to solve each side of the shape, you must remember to multiply by 2. Then, you would not have to keep calculating the same side of the figure.

If there is a problem that does not show the shape in transparent. Draw a new shape you can clearly visualize so you can solve the problem.

For example:

A rectangle has a length of 6 in., a width of 8 in, a height of 1 in., what i the surface area of the figure?

You would have to write the following equations.

(6x8)2= ?

(6x1)2=?

(8x1)= ?

After that, you add your sub answer to get your final answer.

Religion-Jesus suffers for the sins of Humanity

After Jesus shared the Last Supper with his disciples, he went alone to a garden to pray to his Father. Jesus had given himself to his disciples in the Eucharist and was now preparing to give his life for all of humanity. He prayed, “Father, if you are willing, take this cup away from me; still, not my will but yours be done.” (Luke 22:42) Jesus trusted in God his Father and knew God was with him in his suffering. As Jesus prayed he was in “such agony” that his sweat became like drops of blood falling on the ground.

Later that night, Judas Iscariot, one of Jesus’s own Apostles betrayed Jesus in the garden by greeting him with a kiss. By this sign that he had arranged, Judas identified Jesus to those who had come to arrest him. These men took Jesus before the Sanhedrin, the supreme religious court of the Jews, and before Caiaphas, the high priest. Caiaphas said to Jesus, “I order you to tell us under the oath before the living God whether you are the Messiah, the Son of God.” (Matthew 26:63)

Jesus said to the priest, “You have said so.” (Matthew 26: 64). The high priest said, “He is blasphemed!” (Matthew 26:65). Caiaphas was accusing Jesus of blasphemy, of referring to God in a disrespectful way. And the rest replied, “He deserves to die!” (Matthew 26:66). Jesus was then taken before the Roman governor, Pontius Pilate. When Judas heard this, he regretted what he had done. Judas was so overtaken with grief that he went off and took his own life.

At first, Pontius Pilate wanted to release Jesus, but Pilate’s enemies accused him of trying to stir up a rebellion against the emperor. So Pilate decided to let the crowd decide Jesus’ fate. They shouted out for Jesus’s Crucifixion. And Thus, Pilate handed over Jesus over to them to be crucified.

Special- How to build an Effective Village in Clash of Clans (COC)

Clash of Clans is an game for your ios or android that enables you to apply strategy and probability. It may
not seem like it, but it is indeed true. You may not be the best player, you might be a noob, a beginner, or a novice who is just tired of losing trophies and getting de-ranked to lower leagues. Well, it has to depend on two things, who attacks you and how your village is organized.

Here are some rules that you need to follow in order to ever be good in COC:

• Never leave you town hall on the outside, even if you surround it with defences, a quick rage and healing potion can easily grant that person a star and guarantees his/her victory.
• Always upgrade your defences and barracks to the highest lvl possible before you upgrade your town hall.
• Always use your walls to lead your opponents' troops into your traps. 
• When attacking, always make sure that you go for the town hall if it is on the outside. Always use the lightning potion to take out the mortars if you are using archers. (Mortars have less range than wizard towers)
• Send in your Barbarian King as a last resort when attacking, it is useful for the King to fight during
  
  defence battles.

Now that you have the basics to Clash of Clans, you must learn how to build a good, strong base.  Your main goal for defence is to protect your loot and prevent other people from stealing your loot. The best way to do this, since you will most likely not have enough walls to protect your entire village is that you must always put your storages surrounded by walls. It is also usually a good idea to put it at the center along with your town hall. It is also a good idea if you put your mortar at the center. Since mortars have long range, they also have the least amount of health and are very vulnerable to lightning potions. 2 lightning potions can destroy a mortar. My village has a Barbarian King, Town Hall 7, dark elixir storage, mortar and 2 wizard towers at the center surrounded by my best walls. Here's the most important thing. Make sure that you have
at least two defence guarding the things that you might decide to put outside so that they could start dealing damage as soon as possible. Also, always put your army camps, barracks, spell factories, and clan castle on the outside because they usually have no use to you at all. Usually, you would put the clan castle within the walls, but thanks to the new update by Supercell, enemy troops can no longer steal loot from the clan castle. That is all the essentials you need in order to have a good village in Clash of Clans.
You can join clan Aftermath using the advanced search options: War frequency: Always. Trophies required: 800. In the clan, you should see at least one of these elders: Naruto, King Zeus, Raymond.
Thanks.

The Eucharist- The Sacrament of Sacraments

The Eucharist is the source and summit of all Christian life. However, the Eucharist is also the most confusing
and the most complicated of all sacraments. This article will only go over and review the basics of the Eucharist.
The first thing that Catholics must understand is that the Eucharist is truly the Body and Blood of Christ. The Sacrament of Eucharist does not represent any symbols but it is truly and really the Body and Blood of Christ but just in the form of bread and wine. In the Eucharist they have become Christ- body and blood, soul and divinity. Jesus himself told us that, "I am the living bread that came down from heaven; whoever eats this bread will live forever; and the bread that I give is my flesh for the life of the world." (John 6:51)
He went on to say, "Unless you have eaten the flesh of the Son of Man and drink his Blood, you do not have life within you. Whoever eats my flesh and drinks my blood has eternal life and I will raise him on the last day. For my flesh is true food and my blood is true drink." (John 6:53-55)
As Catholics, we believe that the celebration of the Eucharist makes present to us the sacrifice Jesus offered once and for all on the cross. At the Eucharist, we remember Good Friday not merely as a story or an event from the past, but the sacrifice of Jesus is a mystery; it is more than words can say. It is a mystery we remember and make present each time we celebrate the Eucharist.

Math- How to Simplify and Solve Radicals and Square Roots

Roots" (or "radicals") are the "opposite" operation of applying exponents; you can "undo" a power with a radical, and a radical can "undo" a power. For instance, if you square 2, you get 4, and if you "take the square root of 4", you get 2; if you square 3, you get 9, and if you "take the square root of 9", you get 3:   Copyright © Elizabeth Stapel 1999-2011 All Rights Reserved

The "" symbol is called the "radical"symbol. (Technically, just the "check mark" part of the symbol is the radical; the line across the top is called the "vinculum".) The expression "  " is read as "root nine", "radical nine", or "the square root of nine".You can raise numbers to powers other than just 2; you can cube things, raise them to the fourth power, raise them to the 100th power, and so forth. In the same way, you can take the cube root of a number, the fourth root, the 100th root, and so forth. To indicate some root other than a square root, you use the same radical symbol, but you insert a number into the radical, tucking it into the "check mark" part. For instance:

The "3" in the above is the "index" of the radical; the "64" is "the argument of the radical", also called "the radicand". Since most radicals you see are square roots, the index is not included on square roots. While "  " would be technically correct, I've never seen it used.

a square (second) root is written as 

a cube (third) root is written as 

a fourth root is written as  

a fifth root is written as:  

You can take any counting number, square it, and end up with a nice neat number. But the process doesn't always work going backwards. For instance, consider , the square root of three. There is no nice neat number that squares to 3, so  cannot be simplified as a nice whole number. You can deal with  in either of two ways: If you are doing a word problem and are trying to find, say, the rate of speed, then you would grab your calculator and find the decimal approximation of :

Then you'd round the above value to an appropriate number of decimal places and use a real-world unit or label, like "1.7 ft/sec". On the other hand, you may be solving a plain old math exercise, something with no "practical" application. Then they would almost certainly want the "exact" value, so you'd give your answer as being simply "".
