1 ) The first terrarium was developed by botanist Nathaniel Bagshaw Ward in 1842. He was interested in studying insect behaviour. Once he accidentally left one of his bug jars open. A fern spore in the jar sprouted, grew and germinated into a new plant. This is how the first terrarium had been created.
2 ) <span />Because of the different conditions within, terrariums there are two, which can be classified as closed and open. Closed terrariums have a lid to enclose the plants entirely within the glass container. Open terrariums do not require a lid.
Sorry working on this right now as well, and I don't have the others yet :(

The total batches of cupcakes that you make with one small bag of sugar will be 22 batches
From the question, we are given the following
Weight of a small bag of sugar = 2.265kg = 2265grams
Since 100g of sugar to make one batch of cupcakes, then:
100g = 1 batch ... 1
In order to get the number of batches of cupcakes can you make with one small bag of sugar, we can write:
2265g = x ... 2
Divide both expressions;
100/2265 = 1/x
100x = 2265
x = 2265/100
x = 22.65 batches
Hence the batches of cupcakes that you make with one small bag of sugar will be 22 batches

Answer:
The correct answer is: Hydrophobic, Hydrophobic.
Explanation:
- Proteins are made up of polypeptide chains which are formed by the polymerization of amino acid molecules, linked together by peptide bonds.
- The amino acids can be broadly classified into non-polar and polar.
- The non-polar amino acids can be defined as those amino acids whose side chains possess hydrocarbon molecules only. They do not possess any charge and are incapable of forming hydrogen bonds with water molecules. They tend to avoid water and so they tend to remain buried into the interior of a protein. Examples can be illustrated as Leucine, Valine, Isoleucine, Phenylalanine, etc.
- The polar amino acids can be defined as those amino acids whose side chains either possess a charge (positive or negative) or a hydroxyl group which is capable of forming hydrogen bonds with water molecules. As they tend to form hydrogen bonds with water molecules they are usually found on the surface of the proteins. Examples can be illustrated as Lysine, Arginine, Serine, Asparagine, etc.
Answer:
Option D, has only a single opening
Explanation:
A gastrovascular cavity has only one opening. The food goes in and comes out of the same opening there by making it a two way digestive tract.
However, a digestive tube is a one way digestive tract where the food goes in from mouth (one end) and comes out of anus (second end) . It is also called as alimentary canal
Hence, option D is correct
Decomposers are organisms that break down dead material in an ecosystem.
