D.) Because the leaf is coated in lipid molecules

A is wrong because water is polar, an example of nonpolar is oil, and everyone knows that oil and water do <em>not</em> mix! Their molecules just aren't attracted to each other.

B is wrong because, like I said, water is polar.

C is wrong because cellulose is one of the most abundant organic compounds on the Earth, and it's a major component of the cell walls in plant cells.

The mammalian tail and
cluponka [151]

The mammalian tail and the human coccyx, the leaves of pitcher plants and cacti, are homologous organs while, the flippers of penguins and dolphins, as well as the shells of turtles and crabs are analogous structures.

<h3>What are homologous organs?</h3>

Homologous organs are those that are similar in structure but operate differently. They resulted from divergent evolution.

Divergent evolution occurs when species are closely connected to the same ancestors but develop similar structures that perform different tasks in different environments.

Analogous Organs are organs from various creatures that, despite their appearance, perform the same function.

In the given case, the mammalian tail and coccyx, as well as the leaves of pitcher plants and cacti, are homologous organs, whereas penguin and dolphin flippers, as well as turtle and crab shells, are analogous structures.

Thus, these are the different instances of homologous and analogous organs.

What pattern of growth will a population with limited resources show?
Paladinen [302]

Answer:

b. logistic

Explanation:

Logistic growth occurs when growth begins as exponential but then slows and flattens out (or becomes constant) at a certain point. The growth of a population is logistic because at the beginning all populations growths are exponential. This is because there are more than enough resources when a population is small. However, once a population reaches carrying capacity, which is the limit an environment can hold, resources begin to run out and the growth becomes slower and constant. Logistic growth is also known as an "S curve" because on a graph the growth resmbles an S.
