What is a food chain? Where do you fit in on the food chain?
Answer:
well a food chain is where there is a line of organisms eat one another
Explanation:
so if you have the sun the sun gives energy to plants like grass so a grasshopper eats the grass and gains that energy. The grasshopper is a primary consumer and then a frog eats the grasshopper the frog is the secondary consumer then a bird eats the frog like a chicken and they are the tertiary consumers. i believe we are tertiary consumers bc they dont get eaten by anything else we are the top of the food chain

What makes elements and compounds different from mixtures? Elements and compounds-
a). have a constant composition
b). are made of gases
c). will not change when heated
d). conduct electric current
Answer:
a). have a constant composition
Explanation:
Let's take water, a compound, as an example. Regardless of how much water you have, there will be one oxygen molecule every two hydrogen molecules. It has a constant composition. The same case is with elements. You'll have a constant amount of atoms per mole. Meanwhile, in mixtures, the composition of everything mixed together is not constant as it is not equal everytime.
Besides, the rest of the choices do not even make sense in the first place...
write a mini-essay about Balanced & Unbalanced Forces
Answer:
Forces have a magnitude (strength) and a direction. Forces can be represented as arrows with the length of the arrow representing the magnitude of the force and the head of the arrow pointing in the direction of the force. Using such arrows, the resulting force (net force) and direction can be determined.
Forces acting on an object can be balanced or unbalanced.

A.
The insulin produced by bacteria can be used to help treat people with diabetes.
B.
E. coli bacteria are one of the main causes of the disease, diabetes.
C.
The bacteria can be injected into a person with diabetes and permanently cure him or her.
D.
all of these
Insulin is a hormone that regulates the breakdown of glucose for energy insulin produced by bacteria can be used to help treat people with diabetes.
What is the function of insulin?Numerous toddlers and teenagers suffer from the dangerous condition known as type 1 diabetes. Insulin, a hormone that controls blood sugar levels, is no longer produced by the pancreas as a result of the condition.
The smallest blood vessels in the body eventually suffer harm from high blood sugar levels. In order for blood sugar to be utilized as fuel by the body's cells, insulin aids in its absorption.
The liver receives a signal from insulin to store blood sugar for later use. When blood sugar enters cells, blood sugar levels fall, which tells insulin to do the same.
Therefore, glucose from the blood can be absorbed by the cells in the muscles, fat, and liver by insulin, hence option A is correct.

Petroleum products, which contain carbon, are burned, and the carbon escapes into the atmosphere, as carbon dioxide, BUT, how does it get into the petroleum in the first place?
Answer:
they got there because of the chemicals that the carbon has
Explanation:
Carbon from plants and animals that lived millions of years ago is stored in rocks like limestone and fossil fuels like coal and oil. Slow geologic processes trapped the carbon from these organisms' deaths and converted it into these natural resources.
What form of carbon is in fossil fuels?As previously stated, fossil fuels are hydrocarbons. When hydrocarbons are burned in the presence of oxygen, carbon dioxide is released into the atmosphere. Carbon dioxide is a greenhouse gas that contributes significantly to global warming.FOSSIL FUEL : The compounds that make up plankton and plants transform into fossil fuels after millions of years underground. Plants decompose into coal while plankton decomposes into natural gas and oil.Carbon compounds are used as fuel because they burn cleanly and produce no smoke. Carbon compounds have higher calorific values, a higher maximum ignition temperature, and their combustion is more controlled. As a result, carbon and its compounds are an excellent source of fuel.To learn more about : Fossil fuels

Answer:
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have:
1. a membrane-bound nucleus
2. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria)
3. several rod-shaped chromosomes
Because a eukaryotic cell’s nucleus is surrounded by a membrane, it is often said to have a “true nucleus. ” Organelles (meaning “little organ”) have specialized cellular roles, just as the organs of your body have specialized roles. They allow different functions to be compartmentalized in different areas of the cell.
Or:
Animal Cells
Centrosome:
The centrosome is a microtubule-organizing center found near the nuclei of animal cells. It contains a pair of centrioles, two structures that lie perpendicular to each other. Each centriole is a cylinder of nine triplets of microtubules. The centrosome (the organelle where all microtubules originate) replicates itself before a cell divides, and the centrioles appear to have some role in pulling the duplicated chromosomes to opposite ends of the dividing cell. However, the exact function of the centrioles in cell division isn’t clear, because cells that have had the centrosome removed can still divide, and plant cells, which lack centrosomes, are capable of cell division.
Lysosomes:
In addition to their role as the digestive component and organelle-recycling facility of animal cells, lysosomes are considered to be parts of the endomembrane system. Lysosomes also use their hydrolytic enzymes to destroy pathogens (disease-causing organisms) that might enter the cell. A good example of this occurs in a group of white blood cells called macrophages, which are part of your body’s immune system. In a process known as phagocytosis or endocytosis, a section of the plasma membrane of the macrophage invaginates (folds in) and engulfs a pathogen. The invaginated section, with the pathogen inside, then pinches itself off from the plasma membrane and becomes a vesicle. The vesicle fuses with a lysosome. The lysosome’s hydrolytic enzymes then destroy the pathogen.
Plant Cells
Chloroplasts:
Like the mitochondria, chloroplasts have their own DNA and ribosomes (we’ll talk about these later!), but chloroplasts have an entirely different function. Chloroplasts are plant cell organelles that carry out photosynthesis. Photosynthesis is the series of reactions that use carbon dioxide, water, and light energy to make glucose and oxygen. This is a major difference between plants and animals; plants (autotrophs) are able to make their own food, like sugars, while animals (heterotrophs) must ingest their food.
Like mitochondria, chloroplasts have outer and inner membranes, but within the space enclosed by a chloroplast’s inner membrane is a set of interconnected and stacked fluid-filled membrane sacs called thylakoids. Each stack of thylakoids is called a granum (plural = grana). The fluid enclosed by the inner membrane that surrounds the grana is called the stroma. The chloroplasts contain a green pigment called chlorophyll, which captures the light energy that drives the reactions of photosynthesis. Like plant cells, photosynthetic protists also have chloroplasts. Some bacteria perform photosynthesis, but their chlorophyll is not relegated to an organelle.
Vacuoles:
Vacuoles are membrane-bound sacs that function in storage and transport. The membrane of a vacuole does not fuse with the membranes of other cellular components. Additionally, some agents such as enzymes within plant vacuoles break down macromolecules. Plant cells each have a large central vacuole that occupies most of the area of the cell. The central vacuole plays a key role in regulating the cell’s concentration of water in changing environmental conditions. Have you ever noticed that if you forget to water a plant for a few days, it wilts? That’s because as the water concentration in the soil becomes lower than the water concentration in the plant, water moves out of the central vacuoles and cytoplasm. As the central vacuole shrinks, it leaves the cell wall unsupported. This loss of support to the cell walls of plant cells results in the wilted appearance of the plant. The central vacuole also supports the expansion of the cell. When the central vacuole holds more water, the cell gets larger without having to invest a lot of energy in synthesizing new cytoplasm. You can rescue wilted celery in your refrigerator using this process. Simply cut the end off the stalks and place them in a cup of water. Soon the celery will be stiff and crunchy again.

The function of the nucleus is to regulate cell activity.
