Vertebrates have a bilateral symmetry due to which their entire body is divided into right and left halves while the invertebrates either have radial symmetry or the bilateral symmetry. Therefore, option D is correct.

The other basic differences between the vertebrates and the invertebrates are that vertebrates have a spinal cord and a backbone while invertebrates lack them, vertebrates have well developed brain, lungs or gills in respiratory system and closed circulatory system.

Choose ALL of the phases of matter listed<br> that are able to flow:<br> gas<br> liquid<br> solid
IrinaK [193]

Answer:

- gas

- liquid

Explanation:

     Part of the definition of gases and liquids is the ability to flow, so this answers your question.

     Why does this not apply to solids? The cells in a solid are closer together with less room for movement, so they do not "flow" like gasses or liquids. You can think of the device you are asking this question on versus the water in the ocean.

<u>Note</u>: Gas can still flow, but it does not flow the same as water. It depends on what you are being taught for if gas flows or not.

-> Liquid flows from high to low only, while gas can flow in all directions

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

     ★ Also please leave the rating you think I deserve (It helps other users as well as myself)

In a population of 1000 individuals, 500 new individuals were born and 200 individuals died over the course of 1 year. Which equ
blagie [28]

(Initial individuals + newborn individuals) - dead individuals = total individuals

Growth rate = (total individuals/initial individuals) * 100

Population growth rate = new percentage minus 100%

Calculations

(1000 + 500) - 200 = 1500 - 200 = 1300

Growth rate = (1300/ 1000) * 100

= 1.3 * 100

= 130%

Population growth rate = 130% - 100%

= 30% per year if it is uniform
