Scientist rely on <em>Biology </em>concepts when researching crop production and medicine.
1. determine the genotypes of the parent organisms
2. write down your "cross" (mating)
3. draw a p-square
4. "split" the letters of the genotype for each parent & put them "outside" the p-square
5. determine the possible genotypes of the offspring by filling in the p-square
6. summarize results (genotypes & phenotypes of offspring)
Answer:
- gas
- liquid
Explanation:
Part of the definition of gases and liquids is the ability to flow, so this answers your question.
Why does this not apply to solids? The cells in a solid are closer together with less room for movement, so they do not "flow" like gasses or liquids. You can think of the device you are asking this question on versus the water in the ocean.
<u>Note</u>: Gas can still flow, but it does not flow the same as water. It depends on what you are being taught for if gas flows or not.
-> Liquid flows from high to low only, while gas can flow in all directions

Answer:
C. All plankton are closely related to plants.
Explanation:
Plankton are organisms found in water that exist in a drifting state. They are too small or weak to swim on their own, so they let the current or tide carry them. They are usually microscopic but include larger species as well, such as some crustaceans and jellyfish.
Phytoplankton are autothrophic plankton. This means that they produce their own food. They are primary producers and closely related to plants.
Zooplankton are heterotrophic plankton, which means that they feed on other organisms. They are animals and aren't closely related to plants.
Nekton are organisms found in water that swim actively.
Based on this information, we can conclude that statement C is the only incorrect statement.
Answer:
they carry out experiments to understand it
Explanation:
Scientists raise hypotheses which are tested by experiments made under controlled conditions in order to explain a particular topic. When a hypothesis is confirmed by the experimental data, the evidence obtained from this experiment provides the basis to increase the scientific knowledge about a particular issue. In consequence, experimentation can be considered as a critical step in the scientific method and research aims to advance knowledge of a particular phenomenon by confirming a hypothesis, which must be testable (i.e. verifiable as a result of further experimentations).
