Arachidonic acid (ARA) and docosahexaenoic acid (DHA) are two long-chain fatty acids necessary for the development of Multiple C
lana [24]

Answer:

The correct answer is: the nervous system, brain, and eyes.

Explanation:

Arachidonic acid (ARA) and docosahexaenoic acid (DHA) are long-chain polyunsaturated fatty acids that have great nutritional value, as they are omega-6 and omega-3 fatty acids, respectively, meaning they are essential fats that cannot be produced by the body and, therefore, need to be part of the diet.

The consumption of ARA and DHA has been directly linked to the development of the brain and the retina, and the inclusion of these fatty acids in the nutrition of infants has been proven to be extremely beneficial to their growth.

Besides their functions in the development of the nervous system and the eyes, ARA and DHA play a role in maintaining a healthy immune system and preventing cardiovascular conditions.

Does any landform on Earth’s surface look the same as it did 5 million years ago? explain why or why not.
Sophie [7]

Answer:

Earth's surface didn't look much different. With few exceptions.

The global climate is cooler and drier, and seasonal, similar to modern climates. As the climate began to cool down grasslands continued to expand and forests started to dwindle in extent. In the seas, kelp forests made their first appearance and soon became one of Earth's most productive ecosystems. Water from the Atlantic Ocean poured in through the Strait of Gibraltar to deluge the Mediterranean Basin. The event is called the Zanclean flood. Parts of of southern Norway and southern Sweden that had been near sea level rose to form the Hardangervidda plateau and the South Swedish highlands.

Shorty after, the glaciations, uplift of the Rocky mountains and Panama seaway closure began to reshape the Earth.
