Answer:
Origin of whales
Natural selection
Modern understanding
Explanation:
<u>Origin of whales</u> - In the first edition of "On the Origin of Species" in 1859, Charles Darwin speculated about how natural selection could cause a land mammal to turn into a whale.
<u>Natural selection</u> - To understand the origin of whales, it's necessary to have a basic understanding of how natural selection works. Natural selection can change a species in small ways, causing a population to change color or size over the course of several generations. This is called "micro-evolution."
<u>Modern understanding</u> - Darwin didn't know anything about genetics, Pobiner said. "He observed the pattern of evolution, but he didn't really know about the mechanism." That came later, with the discovery of how genes encode different biological or behavioral traits, and how genes are passed down from parents to offspring.

The answer is ''starfish" or option D. Mitosis is cell division that includes two daughter cells that actually has the same amount of chromosomes as each other. (most likely twins) Mitosis is also part of the cell cycle with meiosis which helps the organism remain homeostasis and homeostasis is the process organism used to stay cold on a arm day, or stay warm on a cold day.

Answer:
The average temperature on Earth would be 0 degrees Fahrenheit because there would be nothing holding in the heat inside the atmosphere.
Explanation:
The Greenhouse effect happens when the heat from Earth gets trapped in the atmosphere, making the Earth warmer. Without the Greenhouse gasses, the heat escapes the atmosphere, leaving Earth to being colder.
the phospholipid bilayer:
1. allows certain substances in and out of the cell
2. allows the water in the cell to stay in and the water outside to stay out.
