Answer: Human use of land has negative impacts. Human activities contribute to the erosion and pollution of beaches. ... More of the rainwater runs off leading to increased erosion and drier soil. Deforestation of land can also lead to desertification and a loss of biodiversity.
Explanation:
Neuromodulation is the release of chemicals (other than ____________ ) from cells that locally regulate or alter the response of neurons to neurotransmitters. The substances released are called ____________ . Neuromodulation generally results in either facilitation or inhibition. When there is greater response from a postsynaptic neuron because of the release of neuromodulators it is ____________ . This may result from either ____________ amount of neurotransmitter in the synaptic cleft or ____________ number of receptors on postsynaptic neurons. When there is less response from a postsynaptic neuron because of the release of neuromodulators, it is called ____________ . This results from either ____________ amount of neurotransmitter in the synaptic cleft or ____________ number of receptors on postsynaptic neurons.
Answer:
Neurotransmitters; neuromodulators; facilitation; an increased; an increased; inhibition; a decreased; a decreased.
Explanation:
In Biology, stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.
Neuromodulation is the release of chemicals (other than neurotransmitters ) from cells that locally regulate or alter the response of neurons to neurotransmitters. The substances released are called neuromodulators. Neuromodulation generally results in either facilitation or inhibition. When there is greater response from a postsynaptic neuron because of the release of neuromodulators it is facilitation. This may result from either an increased amount of neurotransmitter in the synaptic cleft or an increased number of receptors on postsynaptic neurons. When there is less response from a postsynaptic neuron because of the release of neuromodulators, it is called inhibition. This results from either a decreased amount of neurotransmitter in the synaptic cleft or a decreased number of receptors on postsynaptic neurons.

You catch, tag, and release 35 fish back into a pond. Then, you catch 70 more fish, 12 of which have tags on them,
What is the best estimate of the number of fish in the pond?
a 100
b 150
c 142
d 204
Answer:
100
Explanation:
70 + 35 is 105 and if the 12 fish were new it would be 117 which is almost 25 away from 142 but 17 away from 100. hope that makes since!

The brain recognizes action potentials from different sensory modalities as separate and distinct because Group of answer choices the volley of action potentials differs for each sensory modality. action potentials from different sensory modalities are processed through different frontal lobe regions. action potentials from different sensory modalities utilize different neurotransmitter systems. action potentials from different sensory modalities are carried on different nerve tracts.
Answer:
The correct answer is ''action potentials from different sensory modalities are carried on different nerve tracts.''
Explanation:
A nerve tract is a set of axons (bundles of nerve fibers) of the central nervous system that have the same origin and the same destination. Each of the main sensory types that we can experience, pain, touch, vision, sound, etc., is called sensation modality. Nerve fibers only transmit action potentials whatever the stimulus. The perceived modality will depend on the specific point in the central nervous system where the excited fiber ends, that is, the response indicates that each nerve bundle ends at a specific point in the central nervous system and the type of sensation experienced when a nerve fiber is stimulated is determined by the area of the nervous system to which this fiber leads. For example, if a fiber is stimulated for pain, the person perceives this sensation regardless of the type of stimulus that excites them. It can be electricity, overheating the fiber, crushing it, or activating the nerve ending for pain when tissue cells are injured. In all these cases, the person perceives pain. Similarly, if a tactile fiber is stimulated by electrical excitation of a touch receptor or by some other mechanism, the person perceives a sensation of touch because these fibers lead to specific areas of touch in the brain. In this same sense, the fibers from the ocular retina end in the visual areas of the brain, those from the ear end in the auditory areas and the thermal fibers in the areas for temperature. This specificity of nerve fibers to transmit nothing more than a sensation modality is called the principle of the marked line.
How does the color adaptation help fish residing in the coral reefs?
Answer:
Fish found in coral reefs also have bright coloring to help with mating or camouflage. Due to the wide variety of prey found in coral reefs, the fish have developed a generalized feeding structure to take advantage of the biodiversity. Lastly sessile animals, such as coral, have adapted toxins to keep away predators.
Explanation:
Answer:
Many fish have color patterns that help them blend in with their environment. This may allow the fish to avoid being seen by a predator. Some fish, such as the flat fishes (Pleuronectiforms) , can change their skin coloration to match the surrounding habitat. Fish can also have disruptive markings to hide body parts

Suppose you coated the leaves of a plant with petroleum jelly. How would the plant's rate of transpiration be affected?
Answer:
The rate of transpiration would decrease
Explanation:
the petroleum jelly would block the stomata of the leaves resulting in decreased transpiration rates
Petroleum jelly would inhibit the loss of moisture out of the stomata cells. Therefore, the rate of transpiration would be decreased.
What is transpiration?Transpiration exists the procedure of water movement via a plant and its evaporation from aerial parts, such as leaves, stems, and flowers. Water exists essential for plants but only a small amount of water brought up by the roots is utilized for growth and metabolism. The remaining 97–99.5% exists lost by transpiration. An example of transpiration exists when a plant absorbs water in its roots.
Hence, Petroleum jelly would inhibit the loss of moisture out of the stomata cells. Therefore, the rate of transpiration would be decreased.

Absorb excess water released by digestion.
Answer: Provide support to the body.
Explanation:
The skeletal system is a system which is formed by the bones. The bones are important for the structure and function of the body. The bones are connected with the muscles to allow the movement of the body, and they protect the vital organs like heart, lungs, brains, and others. They provide support to the soft tissues, organs, and muscles of the body. They keep the human body upright. The skeletal system provide shape to the body. It provides support by acting as regions of attachment of soft body parts and muscles.
