Ans.

In a evolutionary or phylogenetic tree, the nodes represent common ancestral species of the descendants, which are represented by the tips of branches, arising from the nodes.

According to the given evolutionary tree, all organisms are evolved from a common ancestor, represented by the last node, which was present about 13 million years ago. Hence, the option 1). is correct.

The second last node is showing a common ancestor to gorilla, chimpanzee, bonobo, and human, which was evolved to different species about 6 million years ago. Hence, the option 3). is correct.

Thus, the correct options are 'option (1). and option (2).'

How is form used in classification?
Yuri [45]
Form classification is the classification of organisms based on their morphology, which does not necessarily reflect their biological relationships. Form classification, generally restricted to palaeontology, reflects uncertainty; the goal of science is to move "form taxa" to biological taxa whose affinity is known.

3. What are 6 things the ocean provides for humans?
Veseljchak [2.6K]

Answer:

What are 6 things the ocean provides for humans?

The Ocean produces more oxygen than the Amazones.

The Ocean regulates the Earth climate.

It is an important source of food.

The best holidays are close to the water.

Many jobs are related to sea activities.

The Ocean has therapeutic properties.

Explanation:

It is often thought that rainforests are the primary source of oxygen on the planet, but the truth is that rainforests are only responsible for 28% of the oxygen on earth while oceans are responsible for the 70%. It does not matter how far we live from the sea, from every ten breaths you take seven come from the ocean

In many ways, the sea regulates our climate. It soaks up the heat and transports warm water from the equator to the poles, and cold water from the poles to the tropics.

The ocean is the number one source of protein for more than a billion people. Fish accounts for about 15.7% of the animal protein consumed globally (2).  Although, not everything is fish and seafood.

The ocean is not just home to us ocean lovers, but it is home to the greatest abundance of life on our planet. When you sail across an ocean, you will see dolphins, whales or a turtle popping up to take a breath.

The ocean is a happy-zone! Our temple, our life, our second home, our exhilaration place. It’s where we swim, surf, sail, dive, chillax, and ‘lime’. Family holidays and Sundays often happen on the beach. For sailors, fisherman and islanders, it also is a transport zone.

The FAO estimates (6) on the most recent official statistics indicate that 59.6 million people in the world were engaged in fisheries and aquaculture in 2016. Only at the European Union level, the blue sector represents 3.362.510 of jobs(7), in 9 subsectors: coastal and maritime tourism, Aquaculture, Renewable Energy, Mineral Resources, Biotechnology, Fisheries, Shipbuilding and Ship repair, Offshore Oil and Gas, and Transport. In fact, 90% of the world trade is made by sea
