CAN FISH SURVIVE ONLY IN WATER WITH DISSOLVED OXYGEN?
Answers
Answer:
Oxygen dissolves into water from two sources: the atmosphere and from plants in the water. kills fish from oxygen depletions can range from “partial” to “total”. In a partial kill the dissolved oxygen level gets low enough to suffocate sensitive species and large fish, but many small fish and hardy species survive.

Place these events in the correct order of occurrence in the muscle contraction: End plate potential triggers an action potential Transverse tubules convey action potentials into the interior of the muscle fiber Acetylcholine binds to receptors on the motor end plate Calcium is released from the sarcoplasmic reticulum Ligand-gated channels open leading to depolarization Calcium ions bind to troponin, which then moves tropomyosin
Answers
Answer:
1. Acetylcholine binds to receptors on the motor end plate
2. Ligand-gated channels open leading to depolarization
3. End plate potential triggers an action potential
4. Transverse tubules convey action potentials into the interior of the muscle fiber
5. Calcium is released from the sarcoplasmic reticulum
6. Calcium ions bind to troponin, which then moves tropomyosin
Explanation:
Acetylcholine (ACh) is a signaling molecule (neurotransmitter) that binds to receptors on muscle cells. This binding triggers the opening of ligand-gated sodium channels, thereby ions enter into muscle cells, which causes the depolarization of the sarcolemma and thus promotes the release of Ca2+ ions from the sarcoplasmic reticulum. The myoneural junction, also known as the motor endplate, is the site of synaptic contact between a motor axon and a skeletal muscle fiber. The endplate potential is the voltage that produces the depolarization of muscle fibers when ACh molecules bind to their receptors in the cell membrane. This depolarization spreads in the sarcolemma through transverse tubules (T tubules) and thus generates an action potential. Finally, this action potential induces the release of Ca2+ in the sarcoplasmic reticulum, which activates troponin protein and induces muscle contraction.

the amount of electrical energy that can be generated by a hydroelectric power plants depends upon
Answers
Answer:
The amount of electricity a hydropower plant produces depends on two factors: How Far the Water Falls. The farther the water falls, the more power it has. Generally, the distance that the water falls depends on the size of the dam.
Explanation:
The amount of electrical energy that can be generated by a hydroelectric power plant depends upon the following factors:
The actual flow rate of water. The height of the water that falls. What is a Hydroelectric power plant?A Hydroelectric power plant may be defined as a renewable source of energy that generates electricity through the utilization of water from dams or diversion structures. Such types of plants are mainly used to transform hydraulic potential energy into electrical energy from water.
The actual flow rate and height of the water from it is falling demonstrate the amount of generated electrical energy. If the amount of water is present in excess quantity with a huge rate of flow and more the height of water in the hydroelectric power plant, it reveals that the generated electricity must be high under such circumstances.
Therefore, the rate of flow and height of water overall reveals the amount of electrical energy that can be generated by a hydroelectric power plant.

Correct option isA0Based on the dispersion of white light into its constituent colours, we can conclude that (a) the white light consists of seven colours(b) the violet light suffers maximum deviation and the red light suffers minimum deviation.
Based on observations from dispersion, it can be concluded that white light is composed of seven colours of light.
What is dispersion of light?Dispersion of light is the separation of white light onto its constituent color as it passes through a refraction prism.
White Light consists of seven colours of varying wavelength.
When light is passed through a refracting prisms, dues the difference in the speed of the different constituents of light, seven colours of light are produced.
Therefore, based on observations from dispersion, it can be concluded that white light is composed of seven colours of light.

The actual number could be much higher, but it is impossible to make a determination about the origin of many other sequences. Why do you suppose it is difficult to make assignments about the origin of many of the sequences in the human genome
Answers
Answer:
TEs are repetitive and mobile elements, thereby it is hard to trace their origins
Explanation:
Repetitive elements are patterns of nucleotide sequences in the DNA characterized to have multiple copies throughout the genome. DNA mini-satellite and Transposable Elements (TEs) are some examples of highly repetitive DNA. TEs are repetitive mobile elements that have the ability to jump within the genome and occupy a major part of eukaryotic genomes. For instance, there is a type of TEs called retrotransposons which mobilize through a copy-and-paste mechanism, thus increasing their number in a genome. In consequence, TEs represent highly repetitive and dynamic genomic sequences, and thereby it is hard to trace their evolutionary histories.

Ecological Succession: Transformation of Communities over Time
Why does secondary succession occur faster than primary succession?
Answers
Answer:
Because there is already presence of soil and nutrients in secondary succession
Explanation:
Ecological succession, which is the series of gradual change that occurs in a community over time, can be of two forms namely: primary succession and secondary succession.
- Primary succession is a kind of succession that occurs in a barren land where no form of life has existed before while secondary succession occurs on a land that has been previously colonized by certain organisms called PIONEER SPECIES, and hence, a substrate containing nutrients called SOIL for growth is available during secondary succession.
This accounts for the reason the secondary succession is faster than the primary succession because there is already presence of soil and nutrients in secondary succession.
Answer:
Soil with nutrients is already present. Seeds are present from earlier occupants, brought in by wind, and/or germinate after fire.
