3 0

Answer:

Water, Solar energy, and Carbon Dioxide.

Explanation:

The overalll reaction of photosynthesis is 6CO2 + 6 H2O -> C6H12O6 (Glucose) + 6O2. This reaction is driven by energy in the form of electromagnetic radiation (light).

As we can see we need CO2, H2O, and light as reactants. And oxygen + glucose (carbohydrates) are our products.

Which of the following is NOT part of the peripheral nervous system?
Ksju [112]

The correct answer is: B. spinal cord  

The nervous system can be divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS). The spinal cord and the brain are part of the CNS, whereas the PNS consists of the nerves that radiate from the CNS to all parts of the body. The PNS includes all neurons that sense and transmit information to the CNS.

The CNS controls thinking processes, movements, and registers the sensations throughout our body. Moreover, the PNS acts to transmit information from the CNS to all parts of the body.

The PNS is in turn divided into two main parts:

1-The Autonomic nervous system (ANS), which regulates involuntary functions and glands. The parasympathetic nervous system is one division of the ANS that controls visceral organs such as glands.

2- Somatic nervous system (SNS), which regulates voluntary muscle movement and transmits information from eyes, ears, and skin to the CNS.

What are the dated fossils called that help scientists to identify or date rocks or fossils?
mamaluj [8]

Answer:

Index fossils

Explanation:

The index fossils are the fossils that come in very handy for the geologists when it comes to identifying or dating rock samples or other fossils. The reason for this is that the index fossils have already been dated. They are fossils that are very commonly found, wide dispersed, are easy to be identified, and are limited to only a certain geological period. These characteristics make them an excellent indicator for the dating of the rock layers in which they are found, or the fossils found in the same layers with them, without conducting further examinations.
