Explanation:
Between prokaryotes and eukaryotes, which type of cells are believed to have evolved first? Scientists have concluded that prokaryote life forms preceded the more complex eukaryotes. All organisms on Earth are classified into two basic cell types. Kary means nucleus.
Answer:
Light travels in straight lines.
Explanation:
Once light has been produced, it will keep travelling in a straight line until it hits something else.
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.

1. Carbohydrates
(There are 3 sources of calories (or energy), which are also known as macronutrients: carbohydrates, protein, and fat.

(The human body does has 4 types of tissue: Epithelial, muscle, connective and nervous tissue).
