Biology

Margarita [4]3 years ago

An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.

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

In photosynthesis, the electron that travels through the electron transport chain in the thylakoid membrane comes from____1____
Step2247 [10]
Answers:
1) Water
2) NADH

--------

1) Water donates the initial electron in photosynthesis. The process of photolysis splits the water into H+ and O2 (oxygen, a byproduct of photosynthesis), and releases electrons which are taken up by photosystem II.

2) The electron transport chain is in the last step of cellular respiration, oxidative phosphorylation. NADH donates the electrons, which are used to pump H+ against the gradient into the intermembrane space of the mitrochondria. These H+ flow back across the membrane through ATP synthase to generate ATP.

Summarize the total response of cortisol induced changes.
belka [17]

Answer:

The degree of cortisol release during high intensity exercise depends in part on the time of day and the timing of meals. When exercise is performed during a time of already high cortisol levels (for example, in the morning), it doesn’t increase above already elevated levels.

Which of the following is the type of DNA repair in which thymine dimers are directly broken down by the enzyme photolyase?
Ainat [17]

Answer: Direct repair

Explanation:

The direct repair of the thymine dimer occurs through the process known as Photoreactivation in the presence of the visible light.

An enzyme known as photolyase recognizes the distortion that is present in the DNA helix, caused by thymine dimer.

This is a type of DNA repair mechanism which is used repair thymine.
