To entice animals and insects to come and pollinate it. They come to drink the nectar and unknowingly pick up pollen and carry it to another plant.
Answer:
atoms (2), community (11) , biome (13), biosphere (14), cells (5), organism (9), ecosystem (12), molecules (3), organ (7), organelles(4), organ system (8) , population (10), subatomic particles(1), and tissues (6)
Explanation:
Levels of organization in order from the simplest to the most complex are:
- Subatomic particles-neutrons, protons and electrons that make up the atom.
- atoms- Smallest particle of a substance that may or may not exist freely.
- molecules- two atoms combine to form molecule. e.g H₂
- organelles- organelles are functioning structures of a cell. e.g. Golgi apparatus.
- cells- organelles combine to form cell. e.g. Parenchyma cells.
- tissue- cells of similar origin and function form the tissue e.g. Cardiac tissue
- organ- tissues combine together to form organs. e.g. Heart
- organ system- many organs combine together to form system. e.g Circulatory system
- organism- several organ system combine to form an organism. e.g. Human being.
- population-organism of same species form a population.
- community- different population combine to form a community.
- ecosystem- communities live in a particular area and interact with the abiotic as well as biotic factors of that area to form ecosystem. e.g. pond ecosystem
- biome-A geographical area where several ecosystem sharing same abiotic factors thrive.e.g. tiaga biome
- biosphere- Narrow zone of the earth where the atmosphere , hydrosphere and lithosphere meet to support life.
Your heart pumps blood so it can circulate to your tissues as well as get oxygen from your lungs, if your heart can’t pump blood well i.e. heart attack you can feel short of breath
Answer:
For the first one the answer is 1) Sodium/potassium pump. For the second one is 2) Active transport. For the last one is 3) b. passive transport osmosis.
Explanation:
1) Sodium/Potassium pump requires ATP for it to start carrying three sodiums to the extracellular fluid and two potassiums to the intracellular fluid.
2) During active transport molecules like glucose, use a protein channel to enter or leave the cell. Although in most cells, glucose goes through the membrane with pumps, it's not general, and in some cells other mechanisms are used. But glucose is always too big to enter the cell with other than active transport.
3) The diffusion of water through a semipermeable membrane is an example of passive transport and osmosis. Water molecules are small enough to go through the cell membrane without any carrier, it also, goes with the gradient, and therefore osmosis happens.
The two point discrimination test
is used to determine sensitivity to touch. This test is performed to evaluate the
ability of an individual to identify two close points on a small area of skin
and how well the individual can discriminate the points. The test can be done by
using calipers.
