Answer:
Coral reef fish are a significant food source for over a billion people worldwide. Many coastal and island communities depend on coral reef fisheries for their economic, social, and cultural benefits. But too much of a good thing can be bad for coral reefs. Download this infographic | Infographic Text
Coral reef ecosystems support important commercial, recreational, and subsistence fishery resources in the U.S and its territories. Fishing also plays a central social and cultural role in many island and coastal communities, where it is often a critical source of food and income.
The impacts from unsustainable fishing on coral reef areas can lead to the depletion of key reef species in many locations. Such losses often have a ripple effect, not just on the coral reef ecosystems themselves, but also on the local economies that depend on them. Additionally, certain types of fishing gear can inflict serious physical damage to coral reefs, seagrass beds, and other important marine habitats.
Coral reef fisheries, though often relatively small in scale, may have disproportionately large impacts on the ecosystem if conducted unsustainably. Rapid human population growth, increased demand, use of more efficient fishery technologies, and inadequate management and enforcement have led to the depletion of key reef species and habitat damage in many locations.

PLZZZZZ HELP!!! WITH 5 STAR THANK AND MARK BRAINLIEST!!! Explain how form and function are related in human cells. Include examples.
Answer:Each cell carries out basic life processes that allow the body to survive. Many human cells are specialized in form and function, as shown in Figure below. Each type of cell in the figure plays a specific role. For example, nerve cells have long projections that help them carry electrical messages to other cells.

choose the correct statement about the earth crust A. the earth crust is thin and could be compared to an eggshell B. most of the earth crust is only 6 km deep C. the earth crust is around 200 km deep D. the earth crust is the thickest layer
''A. the earth's crust is thin and could be compared to an eggshell'' is the correct answer.
Why earth's crust is considered an egg shell?The egg is considered a tiny model of the Earth. The thin shell of the egg represents the Earth's crust which is divided into plates. Both earth and egg have a thin and brittle shells. The crust of the earth is broken into various pieces like the cracked shell of a boiled egg. The mantle of the earth is like the egg white part whereas the core of the earth is present in the center like the egg yolk. The earth's crust is broken into pieces that geologists called it plates. The inside of the planet earth is layered like an egg. Scientists considered the surface of the Earth to be cracked like a big eggshell. They call these pieces tectonic plates that cover the Earth. The plates float slowly on the surface and sometimes crash with each other, and move away from each other.
So we can conclude that option A is the right answer about the earth's crust.

PLEASEEEE ANSWER ITS DUE TODAY Polar bears can have thin medium or thick coats. Due to global warming temperatures at the poles are rising and ice is melting. Only 1 out of 3 polar bear Cubs can survive. Identify the 5 points below in the scenario above.
Answer:
Due to global warming temperatures at the poles are rising and ice is melting is described below in complete explanation.
Explanation:
Global warming is generating Arctic ice to melt at a very fast pace, ice shows sunlight, while water consumes it. Polar bears might be extinct by 2200 because of melting ice, climate modification, research reflects. Fresh research recommends the Arctic animals are in high danger of being killed into extinction by the finish of the century.
What is the end result of DNA replication?
O An mRNA strand that will be used to create a protein.
O two strands of DNA that are identical to cach other
O An MRNA strand that will not be used to create a proteir
O Two strands of DNA that are different from one another.
Answer:
two strands of DNA that are identical to each other
Explanation:
Replication is defined as the process in which two identical copies of DNA is formed from parent DNA strand. The end result of DNA replication is two strands of DNA that are identical to each other which are called chromatids. The process of DNA replication is known as semi-conservative as the end result is consist of one new and one old chain of nucleotides.
Hence, the correct answer is "two strands of DNA that are identical to each other".

Explanation:
Neurons are constantly firing on a regular basis in order to keep your body functioning. In your words, describe how a neuron utilizes a stimulus to create an action potential. (Be detailed)
Answer:
Neurons are in charge of receiving stimuli from the environment, transforming them into nervous excitations and transmitting them to the nerve centers, where they organize themselves to give a response.The cycle of depolarization and hyperpolarization of the membrane and return to the resting membrane potential is called the action potential, an all-or-nothing reaction that can occur at rates of up to 1,000 pulses / second. Membrane depolarization that occurs as voltage gate Na + channels open at one point on an axon passively spreads a short distance and triggers the opening of adjacent channels, resulting in the generation of another action potential. In this way the depolarization wave, or nerve impulse, is conducted along the axon.
Explanation:
Neurons are highly specialized cells whose central function consists in the generation and transmission of signals, in order to communicate with the other neurons of the nervous system and with the outside of the organism. They are made up of three parts: the cell body, the dendrites, and the axon. Dendrites are extensions of the cell body with short, tubular branches, through which each neuron receives signals from other neurons. These signals are added or averaged, and in the event that the total intensity of the received stimulus is greater than a certain threshold, the neuron will generate and emit an electrical response signal. This signal will be sent through the axon, which will transmit the information to other neurons through chemical exchange. The axon divides near the end into thin branches that contact other neurons. The point of contact is called the synapse. At the synapse, there is a gap between the two cells called the synaptic cleft. The synapse is produced by the release of chemicals from the presynaptic neuron that excites the postsynaptic, transmitting the informational code. The arrival of an impulse at the end of a nerve fiber causes a chemical compound, a transmitter substance, to be released, which excites the neighboring neuron. The same neuron may have inhibitory and excitatory connections with different neurons, for which it will need to produce different chemicals that act as transmitters. A neuron receives and integrates multiple stimulations through the synapses, those received by the dendrites are added to those received in the soma so that the electrical potential of the cell membrane ends up exceeding the threshold and originates a nerve impulse in the area of the axonal cone. Nerve impulses are electrical signals generated by the spike trigger sites (axon cones) of a neuron as a result of membrane depolarization, which are conducted along the axon to its termination. The transmission of impulses from the endings of a neuron to another neuron, a muscle cell or a gland occurs at the level of the synapses.
What is the other main type of chemical bond?
Answer:
Explanation:
Answer:
answer (UNDER)
Explanation:
Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other.
