Why did removing bees have a bigger effect than removing the rabbits?
I think removing bees have a bigger effect than removing rabbits because bees help a lot with our earth and some things would probably be bad without them. Bees do things like help plants grow, breed and produce food, and they transfer pollen between flowering plants so they can keep the cycle of life turning. Plus they make great honey ! But with the rabbits they can sometimes cause damage to the earth by overgrazing native and sown pastures, leading to loss of plant biodiversity and reduced crop yields. and they also compete with native animals and domestic livestock for food and shelter, increasing grazing pressure and lowering the land's carrying capacity. So therefore, if we removed bees from our earth it would turn everything upside-down more then it would with rabbits. :)

diffusion stop?
Answer:
Explanation:
Osmosis. Osmosis is the diffusion of water through a semipermeable membrane down its concentration gradient. If a membrane is permeable to water, though not to a solute, water will equalize its own concentration by diffusing to the side of lower water concentration (and thus the side of higher solute concentration).

What things do humans do in the flower garden that alter the biotic elements of
the ecosystem? What effects do they have on biodiversity?
Answer:
Humans often use pesticides to destroy undesirable organisms that live in flower gardens, such as insects, weeds, or fungi. The use of such chemicals will reduce biodiversity. Humans also plant many of the same plants in gardens, which reduces biodiversity.
Humans perform different functions in the flower garden that alter the biotic elements of the garden, which include the usage of most of the pesticides that affect the soil and the microorganisms present in it, the planting of non native species, etc.
What is the significance of human interference in the garden?Human interference in the garden has many negative impacts, such as the introduction of non-native plant species to a garden, which can lead to the replacement of native plants, excess watering and fertilizing lead to an overgrowth of certain species and create an imbalance that changes the naturalness of the garden.
Hence, humans perform different functions in the flower garden that alter the biotic elements of the garden, which include the usage of most of the pesticides that affect the soil and the microorganisms present in it, the planting of non native species, etc.

Which statement best describes the role of DNA?
Answer: It transmits genetic information to the next generation
Explanation:
DNA stores information on how the cell should be made and ‘run’. This is why it is critical that its integrity is well preserved. Otherwise, mutations on DNA can be lethal to the cell. In higher cells, DNA is protected in the nucleolus. To pass down the genetic information, DNA is replicated by DNA polymerases and then during cell division, either copy of the pair goes to each of the two daughter cells.
Answer:
it contains genetic information
DNA strands are organized into small units which are known as genes. Genes carries sequences of bases which instruct the cells which protein is to be synthesized for a particular function in the body.

heres the answers:
1. Cell- work together with similar cells to form structures called tissues.
2. DNA-DNA contains the instructions needed for an organism to develop, survive and reproduce.
3. DNA with a mutation- Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.
4. Nucleus- The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.
5. Organism- Organisms respond to stimuli from their environment and actively maintain their internal environment through homeostasis.
6. Proteins- Your body uses protein to build and repair tissues.
7. Ribosome- Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule.
8. Amino acid - When you eat protein, your body breaks the protein down into amino acids. Those amino acids are then used to repair and grow new muscle fibers. When you consume an adequate amount of protein, your body will experience something called a positive balance of nitrogen.

Which continent is located southeast of the Indian Ocean?
Answer:
Australia and Antarctica. Antarctica would be more south.
Explanation:
8. Alexander was studying the effect of playing rock music on plant growth.
One of the plants was exposed to rock music for 24 hours a day for a
period of 6 weeks. Data on the growth of the plant was collected at
the end of each week and plotted in a graph. Based on the data,
which would be the MOST reasonable measurement at the end of an
8-week period?
A. 2 decimeters B. 6 decimeters
C. 8 decimeters D. 16 decimeters
Answer:
C. 8 decimeters
Explanation:
As seen on the graph, the height of the plant is located on the y-axis while the period of growth or time in weeks is located on the x-axis. If you observe closely, the plant has an average growth of 1 decimeter per week.
week 1 = 1 decimeter
week 2 = 2 decimeters
week 3 = 3 decimeters
week 4 = 4 decimeters
week 5 = 5 decimeters
week 6 = 6 decimeters
week 7 = 7 decimeters
So, this means that at the end of the 8-week period, the plant's height is at 8 decimeters.

Explanation:
In the lung ballin model, the plastic at the bottom acts as the diaphragm. Diaphragm is a strong muscle that expand and contracts that cause air to flow in and out of the lungs. The movement of the balloon matches with breathing. When someone breathe in, air moves into the lungs like the balloons and it is because the diaphragm/plastic expands and these make air to enter through the straw which represent trachea and when you breathe out, the diaphragm contracts which allow air to move out.

Cells contain small specialized structures called___________that act just like organs in your body
Answer:
Organelles
Explanation:
Organelles are specialized structures that perform various jobs inside cells. The term literally means “little organs.” In the same way organs, such as the heart, liver, stomach, and kidneys, serve specific functions to keep an organism alive, organelles serve specific functions to keep a cell alive.
Cells contain small specialized structures called organelle that act just like organs in your body.
What are cell organelles?An organelle is a subcellular structure that, like an organ, has one or more specific jobs to do in the cell.
The nuclei, which store genetic information, mitochondria, which produce chemical energy, and ribosomes, which assemble proteins, are among the more important cell organelles.
The major organelles and cellular structures found within the cytoplasm include the nucleolus, nucleus, ribosome, vesicle, rough endoplasmic reticulum, Golgi apparatus, cytoskeleton, smooth endoplasmic reticulum, mitochondria, vacuole, cytosol, lysosome, and centriole.
The nuclei, which store genetic information, mitochondria, which produce chemical energy, and ribosomes, which assemble proteins, are among the more important cell organelles.

Answer:
DNA
Explanation:
I did the assignment. and got a 100
The displayed segment is a part of a DNA MOLECULE. This nucleic acid (DNA) forms a double helix.
The deoxyribonucleic acid (DNA) is a double helix molecule composed of two long chains of nucleotides, which interact by hydrogen bonds.
Conversely, the ribonucleic acid (RNA) molecule is a single-stranded molecule consisting of a long chain of nucleotides.
In DNA, there are four types of nucleotides, each containing one distinct nitrogenous base, i.e., Adenine, Guanine, Cytosine and Thymine.
According to the base pair rules, Adenine always pairs with Thymine via two hydrogen bonds, whereas Guanine pairs with Cytosine through three hydrogen bonds.
In RNA, Thymine bases are replaced by Uracil bases.
