Cells Questions And Weather Review

If your answer is something like what the correct answer says, then you were right, even if it says you were wrong. The most important point is that you know it is where photosynthesis happens.

Cells are the building blocks of living things because they are the pieces that living things are made of, just like atoms are the building blocks of matter.

See how there is the word MOTION as part of the word!

All cells need nutrients. The nucleus is where genetic material (DNA) is found. Only living things are made of cells.

Weather = matter (air and water) + energy (heat). Also, we did not talk at all about how the Sun or Moon changes position or about tectonic plates (those are UNDERGROUND!)

This is one of the characteristics of all living things!

All cells need nutrients to provide energy for the work they do. Nutrients, such as carbohydrates, proteins, and fats, are broken down during cellular respiration to produce ATP, which is the main source of energy for cells. Chloroplasts are only found in plant cells and are responsible for photosynthesis, not energy production. Atmospheric nitrogen and carbon dioxide are not directly used for energy production in cells.

All living things need energy is one of the seven characteristics of all living things. This energy is usually in the form of food or heat. Not all living things have blood (plants, mold, single-cell organisms).

Chloroplasts are found only in plant cells and are responsible for photosynthesis, the process by which plants convert sunlight into energy. Cell walls are also unique to plant cells and provide structural support and protection. Mitochondria and nucleus are found in both plant and animal cells. Endoplasmic reticulum and ribosomes are present in all cells and are involved in protein synthesis. Cytoplasm and cell membranes are also found in both plant and animal cells. Therefore, the correct answer is chloroplasts and cell walls.

all of the others are made of more than one cell.

Multicellular means they are made of more than one cell. An ameba is made of only one cell. Reproduce asexually means that it can make copies of itself completely on its own. Everything in the picture except the ameba needs one other organism like it to make copies of itself.

Remember that Weather = Matter (Air and water) + energy (HEAT!)

Weather happens only in the lowest layer. These layers are listed by how close they are to Earth's surface. Remember TSMTE: Timmy steals money to eat.

The correct answer is "The parts of something that it is made of on the inside (like organelles)". An internal structure refers to the components or parts that make up the inside of something, such as an organism or a cell. In the context of this question, it specifically refers to the internal components of a cell, known as organelles. Organelles are specialized structures within a cell that perform specific functions, such as the nucleus, mitochondria, and endoplasmic reticulum. These organelles make up the internal structure of a cell and contribute to its overall function and organization.

The atmosphere is the air surrounding Earth, so the only answer could be a weather event (something that happens in air). Tides are movement of the oceans (hydrosphere). Eclipses are movement of the Moon in front of the Sun. Earthquakes are movement of the ground (lithosphere). Tornadoes are a weather event, in the air (atmosphere). If thunderstorms, blizzards, hurricanes, rain, or any other weather event were choices, those would have been correct, too.

The cell membrane is responsible for controlling the movement of substances in and out of the cell. It acts as a barrier, allowing some molecules to pass through while preventing others from entering or leaving. This selective permeability allows the cell to maintain its internal environment and regulate the exchange of nutrients, waste products, and other molecules with its surroundings. The cytoplasm is the gel-like substance within the cell, the nuclear membrane surrounds the nucleus, and the cell wall is a rigid structure found in plant cells that provides support and protection.

THIS IS A VERY TRICKY QUESTION. For answer A, again, genetic material is found in the nucleus. Answer B describes all living things but not all cells. This is because not all cells grow and reproduce, even though all living things grown and reproduce. C is the correct answer because no cell can function without nutrients. That is what gives them energy. D is not correct because not all cells are found in multicellular organisms, some can only be found in single-cell organisms.

Again, these layers are in order of how close they are to Earth's surface. The one on the bottom is being pressed down on most by the others (like a football player at the bottom of a pile), so its gases are pushed together (concentrated) more than the other layers.
