Answer:
Carbohydrates are used by the body for energy and structural support in cell walls of plants and exoskeletons of insects and crustaceans. They are made of smaller subunits called monosaccharides. Monosaccharides have <u>carbon</u>, <u>hydrogen</u>, and <u>oxygen</u> in a 1:2:1 ratio.
Difinition of disaccharides: any of a class of sugars whose molecules contain two monosaccharide residues.
Make an example...
Short carbohydrate chains are called <u>oligosaccharides</u> and contain 3 to 10 sugar molecules. Long carbohydrate chains can contain hundreds or even thousands of monosaccharide units. molecule of <u>glucose</u> and one molecule of <u>fructose</u> joined together.

Explanation:The musculoskeletal system provides form, support, stability, and movement to the body. It is made up of the bones of the skeleton, muscles, cartilage, tendons, ligaments, joints, and other connective tissue that supports and binds tissues and organs together.
Answer:The Rainforest mesocosm, at the north end of Biosphere 2, was created to simulate several tropical Rainforest habitats. The biome can be divided into the following habitats: Bamboo belt of dense bamboo species was intended to screen the biome from airborne salt that might be entrained from the ocean biome.
Explanation: yes
The Earth core has two layers: the outer core, and the inner core. Moreover, the magnetic field protects Earth from solar weather.
The Earth's magnetic field is an invisible layer that protects life from the majority of the solar wind blast.
The magnetic field covers us from charged solar particles that crash into it and then flow around it.
Moreover, the Earth core has two layers: the outer core and the inner core, which are separated by a boundary known as the Bullen discontinuity.

Answer:
Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.
Explanation:
You need to prepare 250. mL of a 0.550 M aqueous solution of sucrose, C12H22O11 (aq),
which is used frequently in biological experiments.
Based on your answer above, what is the value of x?
Solution:
A 0.550 M aqueous solution contains 0.550 mole of sucrose per liter of solution.
250 ml = 0.250 liter
Thus a 0.250 liter of a 0.550 M aqueous solution of sucrose contains 0.250 * 0.550 = 0.1375 mole of sucrose
Recall:
Mass = number of moles * mass of 1 mole
mass of 1 mole of C12H22O11
= 12(12) + 1(22) + 16(11)
= 144 + 22 + 176
= 342 grams
Mass = 0.1375 * 342 = 47.025 grams of sucrose.
Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.
