Hypothesis is what you think will happen before the experiment, it isn't necessarily backed up by any sources or evidence. A scientific law is the observation of a phenomenon and a theory is the explanation both can be used together to back each other up.

Describe the function of each organelle.
Elis [28]

Answer:

Cytoplasm: Fluid between the cell membrane and the nucleus. helps protect organelles

Nucleus: A part of the cell containing hereditary information and is responsible for growth and reproduction; the "command center" of the cell.

Ribosome: A small particle in the cell that can make proteins.

Endoplasmic Reticulum: A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.

Golgi Apparatus: A cell structure that helps make and package materials to be transported out of the cell or for storage inside the cell.

Lysosome: Cell organelle filled with enzymes needed to break down certain materials in the cell, such as large food particles or old parts of the cell. May be found only in animal cells.

Vacuole: Saclike storage structure in the cell. can store water, nutrients, and even toxic substances.

Mitochondrion: An organelle containing enzymes responsible for producing energy. (Metabolism/respiration)

Chloroplast: An organelle found in the cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy (photosynthesis).

Cell membrane: The thin, flexible barrier around a cell; controls what enters and leaves the cell.

Cell wall: The structure outside of the cell membrane that is used to provide support and protection. Present in plants, algae, fungi, and many prokaryotes.

Which geological feature is most common at oceanic-continental convergent boundaries?
alex41 [277]

Trenches are geological feature is most common at oceanic-continental convergent boundaries.

Explanation:

Usually, the oceanic plate, because it is denser, becomes subducted underneath the continental plate. The enormous stress of the two colliding plates causes the plates to warp abit downwards along the boundary causing a trench to form that stretches the boundary.

As the oceanic plate gets subducted and ‘dives’ into the mantle, it begins to melt into magma. Usually, due to the enormous stress along the boundary, fissures develop on teh continental plate along teh boundary. The magma rises through these fissures and erupts at the surface. Several mountains form long the boundary forming another signature geological feature of convergent boundary which is volcanic arc mountains.

Chloe reads that given the correct conditions, cuttings from certain plants will form roots along the stem, enabling a new plant
Archy [21]

Answer:

The correct answer is - If you use the rooting hormone when cloning plants from cuttings, then it will be beneficial for the cuttings.

Explanation:

A hypothesis is a possible explanation or solution behind the particular natural world process or phenomenon. It is formed on the basis of the observation of the phenomenon or process, how it works or what characteristics it shows.

In this study, it is found that the root hormones promote the growth in the clonings from the cuttings of plants thus, the provided hypothesis is the correct hypothesis for the experiment given.
