Answer:
C- Plant cells make their own food, but human cells do not.
Explanation:
Animal cells must take food in from some other source. Plants, on the other hand, have the ability to make their own food through a process called photosynthesis. In essence, the plant cell uses the energy in sunlight to combine carbon dioxide and water to make molecules of glucose and to release oxygen.
D is wrong because the human body uses three types of molecules to yield the necessary energy to drive ATP synthesis: fats, proteins, and carbohydrates. Mitochondria are the main site for ATP synthesis in mammals, although some ATP is also synthesized in the cytoplasm.
A is wrong because plant cells obtain energy through a process called photosynthesis. Secondly, that energy is used to break down carbon dioxide and form glucose, the main energy molecule in plants. Plants, algae and some bacteria use photosynthesis to create energy used for growth, maintenance and reproduction.B is wrong because food provides building materials for your body. Your body needs building materials so it can grow and repair itself. Specifically, it needs these materials to produce more cells and its components. Food contains substances that help control body processes.What is the passage mainly about?

PLSSSSSSSSSS Which best explains why a person can tell the difference between a whisper and a yell?
Sound waves turn into chemical signals that indicate certain sounds.
Different vibrations in the ear cause the brain to interpret different sounds.
The fluid in the cochlea picks up electrical signals for the intensity of sound.
The eyes see what is making the noise and help the brain process the sound.
Answer:
The difference is the louder the sound the bigger the waves and your ears collect the sound waves and brings it to you brain
Explanation:
Proxima Centauri and the Sun are both main sequence stars, but Proxima Centauri is a red dwarf and the Sun is a yellow dwarf. Based on the information you charted, compare the characteristics of red dwarf stars and yellow dwarf stars.
Answer:
Red dwarfs are low-mass main-sequence stars. Yellow dwarfs are main-sequence (dwarf) stars with masses comparable to that of the Sun.
What are 3 reasons deforestation is an issue for animals?
Answer:
- Animals live in the trees
- Animals eat off of tree
-Animals breed in trees
Explanation:
Answer:
1. They have less territory
2. With less space, populations decline.
3. Some animals need trees to survive.
Explanation:
1. Some animals, like wolves, have huge territories that span over miles of land. Deforestation would cause predators to fight over who gets the remaining space.
2. Populations cant thrive if theres no where to have offspring.
3. Animals depend on trees for shelter and food. If there are no more trees, primary and secondary consumers would suffer.

Answer:
A familiar example of homeostatic regulation in a mechanical system is the action of a thermostat, a machine that regulates room temperature.
Explanation:
Answer:
Humans' internal body temperature is a great example of homeostasis. When someone is healthy, their body maintains a temperature close to 98.6 degrees Fahrenheit (37 degrees Celsius). Being warm-blooded creatures, humans can increase or decrease temperature internally to keep it at a desirable level.
Explanation:
You overheard a classmate in the hallway say the following statement.

Do you agree or disagree with him.
If possible could you explain why you agree or disagree it could help me a lot because I’m kinda confused.
Compare the structures for genetics with every day objects. Must include the words: genes, DNA, chromosomes, and nucleus.
Answer:
Genes play an important role in determining physical traits — how we look —and lots of other stuff about us. They carry information that makes you who you are and what you look like: curly or straight hair, long or short legs, even how you might smile or laugh. Many of these things are passed from one generation to the next in a family by genes. Most cells have one nucleus. The nucleus is a small egg-shaped structure inside the cell which acts like the brain of the cell. It tells every part of the cell what to do. It contains our chromosomes and genes. Chromosomes come in matching sets of pairs and there are hundreds (sometimes thousands) of genes in just one chromosome. The chromosomes and genes are made of DNA.

Explanation:
Pls pls tell me if im wrong, ill do my best to fix it
B. Interaction with other organ systems.
What is an organ ?An organ within an organism performs specific tasks to maintain the overall health and function of the organism. To accomplish these tasks, an organ typically requires interaction with other organ systems within the organism.
For example, the digestive system works in tandem with the circulatory system to transport nutrients to the cells, while the respiratory system works with the circulatory system to deliver oxygen to the body. By working together, the different organ systems help to maintain the overall health and function of the organism.

In an experiment, equal amounts of heated water and soil were left to cool down. The initial and final temperatures of each were recorded. A partial record of the temperature is shown.
Experimental Record
Substance Initial Temperature Final Temperature
Water 27 °C 24 °C
Soil 27 °C ?
Which statement about the final temperature of soil is correct?
It will be less than 24 °C as soil loses heat relatively faster than water.
It will be less than 24 °C as water loses heat relatively faster than soil.
It will be more than 24 °C as it takes relatively longer to change soil temperature than water temperature.

Basically, there is a presentation of types of food and the amount of those foods over 50 years in this graph. This means the graph is showing amounts of certain foods over the time period. I'm guessing that basing off of the the previous text you're just noting a change in the breaks of birds based off of the diet available to them at certain times. The adaptations and natural selection will explain the changes because due to certain limited and available foods the diet of the birds change.
