Answer:

d. The molecules present in the log are transformed into molecules that contain less energy than the original molecules. The energy difference is the heat of the fire

Explanation:

When a log of wood burns, Oxygen must be present because it is a combustion reaction. A log of wood is composed of organic materials and the main organic material present is Carbon.

Due to the fact that Oxygen is present, Carbon reacts with Oxygen to form Carbon dioxide which contains lesser energy than Carbon.

Elina [12.6K]

Answer:

These islands are barrier islands.

Explanation:

Barrier islands are islands in front of the mainland that separate part of the sea from the open sea. They lie parallel to the coast and have an elongated, narrow shape. On the sea side, dunes often shape the surface, on the land side they are flat. They were created by deposits of waves, currents and wind. Their formation requires a shallow coastal fore, a sufficiently large sediment store and a weak to moderate tidal range.

mamaluj [8]

Answer:

There are many questions that can be answered by science but I will provide some examples below.

Explanation:

Science involves many areas of study, <u>from biology and chemistry to physics and neuroscience</u>. Generating questions and providing answers are the most important steps in science as this process has allowed thousands of scientists to develop new drugs to treat previously-mortal diseases, to protect endangered species, to prevent population declines, to understand the behavior of fauna, among many other remarkable outcomes and discoveries.

In this answer, I will focus on some questions belonging to the life sciences areas that can be answered by science:

Biology

<em />

Ecology

<em>How does the reduction of apex predator populations (terciary consumers) affect the population of secondary consumers?</em>

<em />

Conservation Biology

<em>Why do increased temperatures lead to coral bleaching? What is the mechanism and how can it be controlled?</em>

<em />
