Absorptive cells- Form the walls of the intestines
epithelial cells- Form skin, body cavities, and some organs
Secretory cells- Glands (Sweat)
Nerve cells- Form the nervous system
Sensory cells- Conveys sensory information to the brain (light, smell, taste, ect.)
Muscle cells- Form muscles (body and organs)
Reproductive cells- Allow for reproduction or furthering of the species
Explanation:
C. They make it more fluid
Lipids are composed of fatty acids which form the hydrophilic head and glycerol which forms the hydrophilic tail; their arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties. Via diffusion, 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. Cholesterol, which is comparatively rigid, anchors other molecules attached to the membrane, maintain membrane stability or structural integrity and aid in separating some lipids, helping with membrane fluidity at low environmental temperatures.

The planetary body that Spirit was designed to explore the wide ranges of soil and rocks for clues of the water activity on Mars. Spirit specifically landed at the Gusev Crater which was before, a possible lake in a giant crater.
Answer:
E
Explanation:
This is a glycolysis 2nd reaction, the organic molecule or glucose must be negatively chargedin order to reduce the positively charged NAD+. Oxygen must be present to oxidize the NADH produced back to NAD+ and the free energy liberated when electrons are removed from the organic molecules must be greater than the energy required to give the electrons to NAD+.
B.) crossing over, this is when chromosomes exchange DNA
