The brain and the spinal cord are wrapped in three protective layers of tissue called the meninges. The cerebral spinal fluid goes between these layers to provide more cushion and protection. It nourishes and protects the nerve tissues of the brain and spinal cord. It also acts as a shock absorber, considering humans move a lot and fall.

The central nervous system is supported and protected by two coverings such as bone and membranous coverings.

The central nervous system consists up two major parts such as brain and spinal cord. This system is involved in integrating and coordinating the activities of the whole body.

The major role of the CNS is to control our thoughts, movements, emotions and desires. Beside this, it controls our breathing, heart rate, the release of hormones, body temperature etc.

The fluid present in CNS called as a cerebrospinal fluid which protects our brain from external injury.

As the brain is located within the cranial cavity of the skull and the spinal cord lies in the within the vertebral column, or spine.

The bony coverings, the brain and spinal cord are invested by three concentric membranous envelopes called as Meninges, which protect CNS over ally.

Answer:

c; two electrons and a hydrogen ion

Explanation:

Through redox reactions, NADPH donates protons and electrons, turning into NADP+. The oposite reaction is NADP+ receiving 1H⁺ and 2e⁻ to form NADPH.

----------------------------------

The coenzyme NADPH is named Nicotinamide adenine dinucleotide phosphate. It plays a significant role, during carbohydrates synthesis, in photosynthetic organisms.

During photosynthesis, NADPH is used to assimilate CO₂. The molecule is formed by using the light energy in the electron transporter chain. After that, as a highly energetic molecule, it helps to impulse the Calvin cycle. In posterior reactions, it helps to produce carbohydrates. These molecules are also involved in cell metabolism, providing protons and electrons.

NADP is the most abundant coenzyme in cells, and its most frequent form is NADPH.

This is a REDOX reaction,

⇒  NADP+ reduces and turns into NADPH,

⇒  NADPH oxidizes and turns into NADP+

                 NADPH ⇆ NADP+ + H⁺ + 2e⁻

During the chemical reaction, NADPH donates H⁺ and e⁻, being categorized as a reductant agent.  

The oposite reaction is NADP+ receiving one H⁺ and two e⁻ to turn into NADPH.

Evolution

Explanation:

Evolution is likely would be a cause of natural selection.

Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment has high chances of survival and pass on the genes to their offspring that aided their survival and successful growth.

This process causes species to change with the passage of time and that changes helps in the survival and growth of that species whereas those organisms which can't evolve will die and become extinct so we can conclude that evolution is the cause of natural selection.

Every living thing, including humans, participates in the intricate webs of interconnected relationships known as ecosystems. Thus, an atom which is the smallest unit is the correct option.

A biological community of living things that interacts with its surroundings and other non-living elements is referred to as an ecosystem. An ecosystem is created by how all living things interact with one another, with the physical and chemical components of their environment, and with each other through the movement of energy. It includes every living thing in a specific location along with their nonliving surroundings like air, water, and sunlight. Ecosystems provide for the basic needs of humans. They supply the raw materials we need to meet our needs for food, water, shelter, clothing, and transportation.

A tree is a living being, and it is with a group of birds, insects and microbes, thus an ecosystem.

An ocean is a huge water body which a wide variety of life therefore is an ecosystem and similarly a lake also supports aquatic life, thus it is also an ecosystem.

But an atom is the smallest unit which has no biological components, therefore it cannot be considered as ecosystem.
