dedylja [7]

The correct answer is option A, that is, a ratio of 1 carbon atom to 2 hydrogen atoms to 1 oxygen atom.  

Carbohydrates are the main source of diet, they provide energy to the body, mainly via glucose, a basic sugar, which is a part of the starch and an ingredient in various staple foods.  

The carbohydrates can be signified by the stoichiometric formula, that is, (CH2O)n. It can be also be stated that the ratio of the carbon to hydrogen to oxygen is 1: 2: 1 in the molecules of carbohydrates. Carbohydrates are further categorized into three sub-kinds, that is, monosaccharides, disaccharides, and polysaccharides. The monosaccharides are the simple sugars, for example, glucose.

Lynna [10]

However, most of those eggs doesn't survive, and little frogs are never born in that case. This is why it has to have a lot of eggs so as to ensure that a decent number of offspring survives so as to continue the species.</span>

List at least 3 interesting facts about something you have learned so far in Unit 2 Ecology. Please use at least 2 to 3 Sentence
Oksanka [162]

1.)Coral reefs are busy underwater ecosystems. Some people call them the “rainforests of the sea.” The corals look like rocks but actually are animals. They have hard calcium carbonate skeletons like clams. They form a base for lots of other organisms to live. You’ll find crabs, sea stars, worms, clams, sponges, jellies, sea turtles, and lots of fish. Coral reefs are complicated and very fragile. They are easily affected by pollution.

2.) Tropical rainforests are near the equator where it’s almost always warm and wet. These are the key ingredients for making lots of lush plants and trees. Half of the world’s plants and animals live in tropical rainforests. It’s a very busy ecosystem with many kinds of plants, animals, fungi, and microscopic organisms. Many of them live here and nowhere else.

3.) In the world’s many deserts, there is very little rain. The land is very, very dry. Here, living things have creative ways of finding and saving water. Cactuses are very good at storing water. They can live without rain for months. The kangaroo mouse lives in the Nevada desert. It rarely drinks water. It can get its water from the food it eats.
