Vertebrates are animals with a backbone (think vertebrae). These are the creatures we usually think of when we think of animals. Vertebrates have tremendous diversity in shape, size, ability, and characteristics. They are truly wondrous creatures! The 5 classes of vertebrates are:  

Fish, Amphibians, Reptiles, Mammals, and Birds.

All invertebrates obtain food differently, some have a mouth, and others have a beak. The eight different phyla are, Porifera, Cnidarians, Platyhelminthes, Nematoda, Annelida, Echinodermata, Mollusca, and Arthropoda.

Fossil fuel consists of coal, oil, and natural gas that have been formed from the remains of plants and animals that died millio
Georgia [21]

Answer:The sun

Explanation:

Coal and crude oil are made from the remains of plants and animals that died long ago. The primary energy source in an ecosystem is the sun. Plants take in energy from the sun to produce high energy molecules which are transferred along the food chain to animals. When these plants and animals die, the high energy molecules are now stored in fossil fuels. Recall that the molecules were formed using energy from the sun, therefore, the sun is the energy source from which the high energy molecules contained in fossil fuels are obtained.

How many atoms are in 1.204x10^22 moles of arsenic?
ra1l [238]

Answer:

<h2>0.02 moles </h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

We have

n =  \frac{1.204 \times  {10}^{22} }{6.02 \times  {10}^{23} }    \\  = 0.02

We have the final answer as

<h3>0.02 moles</h3>

Hope this helps you
