It provides energy for the cell to build, repair, and reproduce. Cells needing more energy have more mitochondria.
It makes sense that cell membranes are made of phospholipids because water cant mix in with lipids, so the phospholipids will be able to effectively block out any unwanted water or chemicals suspended in water outside of the cell.
B is the correct answer
A prokaryote cell has no distinct nucleus with a membrane and neither does it have other specialized organelle.
In a eukaryotic cell, the genetic material is DNA in the form of chromosomes which are found within a distinct nucleus.
Examples of prokaryotes Streptomyces soil bacteria (from which streptomycin antibiotic is derived), Escherichia coli bacterium and Streptococcus bacteria (which causes strep sore throat).
Examples of Eukaryotes include protozoa such as amoeba, fungi, plants, animals and generally all multicellular organisms.
Answer:
The answer is the cerebrum.
Explanation:
The brain consists of the following parts; the cerebrum, cerebellum and the brainstem.
The cerebrum is the largest part of the brain located in front. It has two large hemispheres joined by the corpus callosum. The cerebrum has four lobes including frontal, parietal, temporal, and occipital lobes. Functions include: initiation and coordination of movement, memory, touch, hearing etc
The brainstem is composed of the midbrain, the pons, and the medulla. Controls involuntary muscle movements, cardiac function, sneezing etc.
The cerebellum located at the back of the head has two hemispheres. It is controls voluntary muscle movement, posture, balance and equilibrium.
Your answer is the peripheral proteins. Its on the inner or outer surface of the phospholipid bilayer, but not embedded in its hydrophobic core.
