Which additional claim can be BEST supported by the evidence from the skulls in the whale fossil record?

A.
The fossil record shows differences in the skulls of the mammals, which shows that they are from three separate species that all lived at the same time.

B.
The fossil record shows similarities in the skulls of the mammals, which shows that they must have had similar habitats and environments.

C.
The fossil record shows that some mammals evolved so that their nostrils are further at the top of their skull for better breathing while in the water.

Answer: A. Raindrops act like a prism and separate the white light in sunlight.

Explanation:

The reason for the formation of rainbow is option A. Raindrop acts like a prism and separate the white lite into different colors.

Rainbow is an arc of colors from a white light ray which can be formed by the separation of component colors from white light by the combination of reflection, and refraction.

White light absorbs all colors and reflect all of them. That is why a white object is seen white the mix of all colors. When the white light passes through a raindrop, it gets refracted, the refracted light then reflects from the drop and undergo one more refraction and that make the component colors  in the form a bent or arc.

Therefore, raindrop is acting like a prism to separate the white light into its component colors.  Hence, option A is correct.

4) Reduction

5) Reduction

6) Reduction

7) Oxidation

8) Reduction

Explanation:

Oxidation is said to have taken place when there is a positive change in the oxidation number while reduction is said to have taken place when there is a decrease in the oxidation number.

The change from CH3CHO to CH3CH2OH represents on oxidation reaction.

The change from CH3OH to CH4 is a reduction because the oxidation number of carbon changes from +2 to -4.

The change from N2H4to N2 is an oxidation because the oxidation number of nitrogen increases from -2 to 0.

The gain in electrons is a reduction because the gain of electron leads to a decrease in oxidation number.

The change from NO- 2 to NH3 is a reduction because the oxidation number of nitrogen changes from +4 to -3.

The change from NAD+ to NADH is a reduction since NAD+ is the oxidized form of the enzyme while NADH is the reduced form of the enzyme.

The change from CH4 to Co2 is an oxidation because the oxidation number of carbon changes from -4 to + 4.

The change from Ag+ to Ag is a reduction because it involves the gain of one electron and a consequent decrease in oxidation number.

Answer:

the transfer of energy because eating is gaining energy from a source, so the energy from that source is being transfer to the animal.

The transfer of energy is achieved when eating and feeding exists. Chemical processes may emit or absorb chemical energy.

The ability of a physical process to carry out work is known as energy. It's crucial to remember that simply because energy exists doesn't indicate that it is always ready to do tasks. Thermal energy, sometimes known as heat, is generated when atoms or molecules move. It may be thought of as temperature-related energy.

This energy results from the location of an item. For instance, a ball resting on a table possesses potential energy in relation to the ground because of the influence of gravity. Chemical processes may emit or absorb chemical energy. It is created by atoms and molecules establishing or breaking chemical bonds.

Therefore, the transfer energy is achieved when eating and feeding exists.

Answer:

Enteric Nervous System

The enteric nervous system (ENS) is a subdivision of the autonomic nervous system (ANS) that directly controls the gastrointestinal system.

LEARNING OBJECTIVES

Describe the structure and function of the enteric nervous system (ENS)

KEY TAKEAWAYS

Key Points

The enteric nervous system (ENS), which is embedded in the lining of the gastrointestinal system, can operate independently of the brain and the spinal cord.

The ENS consists of two plexuses, the submucosal and the myenteric. The myenteric plexus increases the tone of the gut and the velocity and intensity of contractions. The submucosal plexus is involved with local conditions and controls local secretion, absorption, and muscle movements.

While described as a second brain, the enteric nervous system normally communicates with the central nervous system (CNS) through the parasympathetic (via the vagus nerve ) and sympathetic (via the prevertebral ganglia) nervous systems, but can still function when the vagus nerve is severed.

The ENS includes efferent neurons, afferent neurons, and interneurons, all of which make the ENS capable of carrying reflexes and acting as an integrating center in the absence of CNS input.

The ENS contains support cells, which are similar to the astroglia of the brain, and a diffusion barrier around the capillaries surrounding the ganglia, which is similar to the blood –brain barrier of cerebral blood vessels.

Key Terms

enteric nervous system: A subdivision of the peripheral nervous system that directly controls the gastrointestinal system.

EXAMPLES

The second brain of the enteric nervous system is the reason we get butterflies in our stomach or need to use the restroom more frequently when we are nervous and/or under stress.

The gastrointestinal (GI) system has its own nervous system, the enteric nervous system (ENS). Neurogastroenterology is the study of the enteric nervous system, a subdivision of the autonomic nervous system (ANS) that directly controls the gastrointestinal system. The ENS is capable of autonomous functions such as the coordination of reflexes.

Although it receives considerable innervation from the autonomic nervous system, it can and does operate independently of the brain and the spinal cord. The ENS consists of some 100 million neurons, one-thousandth of the number of neurons in the brain, and about one-tenth the number of neurons in the spinal cord. The enteric nervous system is embedded in the lining of the gastrointestinal system.

Ganglia of the ENS

The neurons of the ENS are collected into two types of ganglia:

The myenteric (Auerbach’s) plexus, located between the inner and outer layers of the muscularis externa

The submucosal (Meissner’s) plexus, located in the submucosa

The Myenteric Plexus

The myenteric plexus is mainly organized as a longitudinal chains of neurons. When stimulated, this plexus increases the tone of the gut as well as the velocity and intensity of its contractions. This plexus is concerned with motility throughout the whole gut. Inhibition of the myenteric system helps to relax the sphincters —the muscular rings that control the flow of digested food or food waste.

The Submucosal Plexus

The submucosal plexus is more involved with local conditions and controls local secretion and absorption, as well as local muscle movements. The mucosa and epithelial tissue associated with the submucosal plexus have sensory nerve endings that feed signals to both layers of the enteric plexus. These tissues also send information back to the sympathetic pre-vertebral ganglia, the spinal cord, and the brain stem.

This is an illustration of neural control of the gut wall by the autonomic nervous system and the enteric nervous system. A sensory neuron is shown to stimulate the nerves in the submucosal and myenteric plexuses, which are connected to nerves in the sympathetic and parasympathetic nervous systems. The sensory neuron is also shown signal the ganglia and central nervous system.

Neural control of the gut: An illustration of neural control of the gut wall by the autonomic nervous system and the enteric nervous system.

Function and Structure of the ENS

The enteric nervous system has been described as a second brain. There are several reasons for this. For instance, the enteric nervous system can operate autonomously. It normally communicates with the central nervous system (CNS) through the parasympathetic (e.g., via the vagus nerve) and sympathetic (e.g., via the prevertebral ganglia) nervous systems. However, vertebrate studies show that when the vagus nerve is severed, the enteric nervous system continues to function.
