Answer:
1) Organisms in this level are either unicellular or colonial (Cellular level).
2) Organisms that live in a group called a colony (Colonial).
3) The work being divided up into specialized tasks (Division of labor).
4) A very long, contracting cell (Fiber).
5) A group of tissues working together as a unit (Organ).
6) A degree of organism complexity. Organisms at this level have their cells arranged into organs (Organ level).
7) The highest level of complexity of a living thing (Organism level).
8) The limiting of the function of a cell to a specific function muscle (Specialization).
9) A group of organs working together for a common purpose (System).
10) Organisms at this level have their cells arranged into systems (System level).
11) Cells working together to perform a particular task division of labor (Tissue).
12) Organisms at this level have their cells arranged into tissues (Tissue level).
Answer: The FDA and USDA cerate food safety programs, safeguards to protect Americans, to protect people from unsafe food. The FDA has monitoring programs for pathogens, naturaltoxins, pesticides, etc.; their methods are science-based.
Explanation:
B) protein channel
Lipids are composed of fatty acids which form the hydrobic tail and glycerol which forms the hydrophilic head; glycerol is a 3-Carbon alcohol which is water soluble, while the fatty acid tail is a long chain hydrocarbon (hydrogens attached to a carbon backone) with up to 36 carbons.
Their polarity or arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties. Via <em>diffusion,</em> small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.
Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Carrier proteins and channel proteins are the two major classes of membrane transport proteins.
- Carrier proteins (also called carriers, permeases, or transporters) bind the specific solute to be transported and undergo a series of conformational changes to transfer the bound solute across the membrane. Transport proteins spanning the plasma membrane facilitate the movement of ions and other complex, polar molecules which are typically prevented from moving across the membrane.
- Channel proteins which are pores filled with water versus enabling charged molecules to diffuse across the membrane, from regions of high concentration to regions of lower concentration. This is a passive part of facilitated diffusion

Well you can give them stuff that they want but that always don't work,so u can be nice to them or ask them what is wrong with them hope this helps :))))))(
B natural changes allow for greater biodiversity
