The death rate will most likely rise and birth rate will end up falling. (Less organisms to populate= less offspring)
AnswerThese are the enterocoelomates.Starfish, sea urchins are examples.Generally animals of the phyla annelida, molluscs and anthropoda belong to this group.
They are animals formed by enterocoely; in which the mesoderm arises from the wall of the embryonic gut archentron. The latter is an hollow outgrowth which forms the coelom.It is the type of coelom found in deuterostome animals.
Explanation:
Smoking causes changes to homeostasis throughout the body best explains the relationship of cause and effect which DeShawn best explains and is denoted as option B.
<h3>What is Homeostasis?</h3>
This is common in biological systems and is the process in which they maintain a stable internal environment through series of techniques such as excretion etc.
Smoking will disrupt the homeostasis in the body as a result of the presence of a high amount of carbon dioxide as against that of the non smoker which has a large concentration of oxygen.
This makes the body internal environment unstable and is therefore the reason why changes to homeostasis was chosen as the correct choice.

Answer:
a. The polarity of membrane phospholipids.
Explanation:
Phospholipids are the amphipathic lipids with polar heads and non-polar tails. The non-polar tails of two lipid layers form the core of the membrane while their heads are oriented towards both of the faces of the membrane. The polarity of the phospholipids does not affect the transport of substances. If a membrane has more of the saturated phospholipid tails in its core, the tight packing of the tails makes the membrane less permeable for large and polar substances.
On the other hand, a membrane with a greater proportion of unsaturated hydrocarbon tails in its core is more permeable. Cholesterol is also an amphipathic sterol and moderates the fluidity of membrane and thereby affects its permeability. A more fluid membrane is more permeable than a more solid membrane. Temperature affects the membrane polarity by affecting the membrane fluidity.
