Frontal lobe
Frontal lobe is situated near the front of the head and it is the most forward of the four lobes of the cerebral cortex. The frontal lobe is the area responsible for primary motor functions and some of the most complex cognitive processes such as memory, problem solving, sexual behaviors, emotional expression, language, and judgment.
The correct answer is: D.carrying messages to other cells
• Allowing polar molecules to enter the cell - Membrane proteins can be involved in transport. This kind of proteins are called channel proteins and usually are integral, transmembrane proteins of the membrane (span across the bilayer). Channel proteins are responsible for facilitated diffusion and active transport of the molecules.
• Recognizing other types of cells- Membrane proteins may function as markers for cellular identification (recognition) and may connect and join two cells together
• Receiving messages – Membrane proteins are often receptors for peptide hormones and thus involved in signal transduction.
Answer:
physical change

Answer:
C
Explanation:
Aggressive behaviour is a act of violence not without it
For starters, a plant cell is able to produce its own glucose through the process of photosynthesis because the plant cell has chloroplasts that take in sunlight, carbon dioxide, and water and turn it into glucose and oxygen. Then, using the glucose, the plant cell is able to break down the glucose in the mitochondria mainly and produce fuel for the cell (adenosinetriphosphate/ATP). It's like having a self sufficient factory! Ya just need light, air, and water access and the factory doesn't need to take in any material like those animal cells. Silly silly heterotrophic animal cells, plants are autotrophs.
Also, plant cell has a cell wall instead of a soft cell membrane like the animal cell does. This provides structure and added protection to the factory. Think of a plant cell factory of more like a building while and animal cell factory a big gelatinous glob (but still solid, very flexible).
The other thing that comes to mind is that plant cells have much larger vacuoles. This means the factory would be able to store lots of goods! Only for the better.
For some odd reason, I had fun writing this. Hope I helped!!
