Answers
Answer:
Explanation: COMPOST BIN
WHAT IS A COMPOST BIN?
A compost bin is a container into which you place organic waste to turn into compost (organic material) over time.
Most compost bins are designed to hasten the decomposition of organic matter through proper aeration and moisture retention. With the proper combination of air and moisture, ideal conditions are produced for the activity of aerobic organisms responsible for the high temperatures that transform the organic materials into compost
Read on to find out how to start a compost bin, DIY compost bin ideas, and more tips for beginners.
The decomposition process will eventually take place over time in a compost "pile" or "heap," even without any housing to contain the matter. However, a compost bin is worth it because it helps speed up decomposition and keeps the area neat. Some bins are continuous, meaning you can keep adding waste to them, while others create batches of compost with a set mix of ingredients you add all at once. Depending on the style of compost bin you choose, bins can also have the advantage of making it harder for rats to get at your compost. This is true of the tumbler type, for example.
CHOOSING THE RIGHT BIN
Select the right bin for your composting needs. You can make an inexpensive compost container out of almost any container or material. Some ideas include:
Plastic storage container
Plastic bucket
Trash cans
Straw bales
Lumber
Branches harvested from the woods
Stone
Cinder blocks
Wire fencing
Ceramic (also popular for a kitchen countertop compost bin)
The best bin, however, is one you can easily turn or rotate consistently to control odors and make sure all the materials decompose. This is especially important for aerobic composting (more information below). A tumbler composting bin is pricey, but you can DIY one from barrels and sawhorses. You can turn compost with a rake or shovel in a non-rotating bin, it just takes more labor to do so.

They are multicellular creatures with pores and channels that let water to move through their bodies, which are made of jelly-like mesohyl sandwiched between two thin layers of cells.
Sea sponges were among the earliest animal groups to form on Earth, but new chemical evidence puts their appearance 120 million years earlier than previously assumed, according to New Scientist.
According to the research, it is found that When there is a sliding of sponges in opposite directions, the sponges will compress. As water filters through the porous shell of a sponge, it develops motion, obtains food and oxygen, and expel waste.
Therefore, Flagella, microscopic hairlike structures inside the sponge, produce currents that filter germs out of the sponge's cells and trap food within them.

Answers
Answer:
1. plasmas
2. special physical forces.
3. solids.
you are most welcome! :D
Answer:
Refer to the explanation.
Explanation:
1.) Plasma is a lot like gases, but the atoms are different because they are made up of free electrons and ions of the element.
In a gas, the atoms or molecules are mostly neutral and not ionized. However, in plasma, the gas is ionized, meaning some or all of the atoms have gained or lost electrons, resulting in the presence of free electrons and ions. These free electrons and ions make plasma distinct from gases and give it unique properties, such as the ability to conduct electricity and respond to magnetic fields.2.) Elements and compounds can move from one phase to another phase when special conditions or factors (such as temperature, pressure, or the addition/removal of heat energy) are present.
The phase of a substance refers to its physical state, such as solid, liquid, or gas. The transition between these phases can occur under specific conditions. Generally, substances change phase when certain thresholds of temperature and pressure are reached, but other factors can also play a role. For example, when a solid is heated to a certain temperature (its melting point), it can transition to a liquid phase, and further heating can turn it into a gas. Similarly, changing pressure can cause phase transitions, such as when a gas is compressed to a certain pressure, causing it to condense into a liquid.3.) The atoms inside of a solid are not allowed to move around too much.
In a solid, the atoms or molecules are tightly packed and held together by strong intermolecular forces. This close arrangement and strong bonding restrict the movement of atoms or molecules, keeping them relatively fixed in their positions. While atoms in a solid can still vibrate around their equilibrium positions, they generally do not have enough energy to move freely throughout the substance like in liquids or gases. This lack of mobility gives solids their characteristic rigidity and shape.This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system.

List three evidences that show that the Bible is the Word of God.
Answers
Answer:1.God tells us that He is the Author (2 Peter 1:20-21 Open in Logos Bible Software (if available) & 2 Timothy 3:15-17 Open in Logos Bible Software (if available))
1.The Old Testament and New Testament Authors understood they were writing the Word of God. Common Old Testament phrase – “Thus saith the Lord”. The Apostle Peter confirmed the Apostle Paul’s writings as Scripture (2 Peter 3:16)
3.Its Historical Accuracy – as verified by archeology, which has never contradicted the Bible, but only confirms and silences its critics.
Explanation:
Answer:
Many people question who the author of the Bible is and wonder if the Bible is really the Word of God. I want to give you five reasons to affirm that the Bible is God's Word.
The Word of God: Evidence that Scripture is Divine
First, I believe the Bible is the Word of God because of its scientific accuracy. The Truth of the Word of God tells us that God “hangeth the earth upon nothing” (Job 26:7). How did Job know that the earth hung in space before the age of modern astronomy and space travel? The Holy Spirit told him. The scientists of Isaiah’s day didn’t know the topography of the earth, but Isaiah said, “It is [God] that sitteth upon the circle of the earth” (Isaiah 40:22). The word for “circle” here means a globe or sphere. How did Isaiah know that God says upon the circle of the earth? By divine inspiration.
Secondly, the Bible is affirmed through historical accuracy. Do you remember the story about the handwriting on the wall that is found in the fifth chapter of Daniel? Belshazzar hosted a feast with a thousand of his lords and ladies. Suddenly, a gruesome hand appeared out of nowhere and began to write on a wall. The king was disturbed and asked for someone to interpret the writing. Daniel was found and gave the interpretation. After the interpretation, “Then commanded Belshazzar, and they clothed Daniel with scarlet, and put a chain of gold about his neck, and made a proclamation concerning him, that he should be the third ruler in the kingdom.” (Daniel 5:29). Basing their opinion on Babylonian records, the historians claim this never happened. According to the records, the last king of Babylon was not Belshazzar, but a man named Nabonidas. And so, they said, the Bible is in error. There wasn’t a record of a king named Belshazzar. Well, the spades of archeologists continued to do their work. In 1853, an inscription was found on a cornerstone of a temple built by Nabonidas, to the god Ur, which read: “May I, Nabonidas, king of Babylon, not sin against thee. And may reverence for thee dwell in the heart of Belshazzar, my first-born favorite son.” From other inscriptions, it was learned that Belshazzar and Nabonidas were co-regents. Nabonidas traveled while Belshazzar stayed home to run the kingdom. Now that we know that Belshazzar and Nabonidas were co-regents, it makes sense that Belshazzar would say that Daniel would be the third ruler. What a marvelous nugget of truth tucked away in the Word of God!

You are working on your senior year science fair project. Your idea is to develop a demonstration to show evidence of how cellular respiration and photosynthesis depend on each other. Your presentation will show how cellular respiration is the process by which all cells transform food into energy, whereas photosynthesis is the process by which plants obtain food. Your experimental design should show evidence of how cellular respiration and photosynthesis depend on each other.
Answers
By using one animal and one plant or tree in an experiment to show that cellular respiration and photosynthesis depend on each other.
How do cellular respiration and photosynthesis depend on each other?The process of Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the producers whereas oxygen is a by-product that is used in the process of respiration and the extra will diffuse in the atmosphere. In the cellular respiration process, oxygen and glucose are converted into water and carbon dioxide. Water and carbon dioxide are the waste material and ATP is the energy that is used in the process. In the photosynthesis process, carbon dioxide gas combines with water molecules forming glucose and oxygen gas while on the other hand, in the process of respiration, glucose combines with oxygen gas forming carbon dioxide gas, water, and energy in the form of ATP. This ATP is used for performing different activities by the cell.
So we can conclude that using one animal and one plant or tree in an experiment to show that cellular respiration and photosynthesis depend on each other.
