Why the surface of motor end plate of skeletal muscle are NOT smooth?
Answer:
The axons that innervate smooth muscle fibers do not have typical branching end feet of the type in the motor end plate on skeletal muscle fibers. ... In the varicosities are vesi-cles similar to those in the skeletal muscle end plate that contain transmitter substance.
Explanation:
Hey mate, here's your answer...
The motor end plate is the neuromuscular junction present at the muscle fibers. The plates of the smooth muscles are not smooth as they contain terminal branches of the nerve axons.
What are motor end plates?Motor end plates are neuromuscular junctions that are chemical synapses formed at the site where the terminal branch of the nerve axons lies and is in contact with the skeletal muscle cells.
The skeletal muscles have the motor end plate, which is an essential synaptic contact created between the axons of the motor nerve cells and the skeletal muscle fiber.
These neuromuscular junctions are important connections that are involved in the transportation of the electrical impulses and signals to make the skeletal muscles contract.
Therefore, the motor end plate of the skeletal muscles is not smooth.

Extra-large breakers are crashing into the surf. How will this affect the undertow? Make a prediction
Answer:
This will make the undertow return to the sea with greater intensity and violence.
Explanation:
Undertow is the movement of the wave in contrast to the sea, that is, it is the movement of the waves on themselves, which makes the sea very agitated, especially when these waves return to the sea with a lot of violence and force. Although this violence and force can be caused by the wind, extra-large breakers can also cause this effect, because the impact of the waves on the breakers, pushes the waves into the sea with more force, making them more violent and intense.

Sea organisms rely on the deep oceanic currents for food and nourishment.
Answer: Currents are powerful physical forces in the seas. They move water and heat around the globe, and help determine the chemical make-up of the water column. Currents also are a major factor in ocean ecosystems. Two types of current motion, upwelling and downwelling, strongly influence the distribution and abundance of marine life.
Upwelling
Currents play a huge role in marine productivity, through a process called upwelling. Sea life is concentrated in the sunlit waters near the surface, but most organic matter is far below, in deep waters and on the sea floor. When currents upwell, or flow up to the surface from beneath, they sweep vital nutrients back to where they're needed most.
Nowhere is the link between ocean circulation and productivity more evident than around Antarctica. There, strong currents pump nitrogen and phosphate up from the deep sea to fuel vast blooms of algae and other plants. These plankton are eaten by swarms of shrimp-like crustaceans called krill. Because of upwelling nutrients, krill are abundant enough to feed the largest animals on earth, baleen whales, as well as myriad penguins, seals, and seabirds. In fact, despite the harsh conditions, the biomass of Antarctic krill is thought to be greater than that of any other animal on Earth.
Downwelling
The importance of upwelling to surface organisms is matched by the need of sea bottom life for downwelling, or the sinking of surface water. Surface water can be forced downward by the pressure of the “pile” of water that forms where currents converge or wind drives the sea against a coastline. But for bottom dwellers, the sinking of water caused by density changes is especially noteworthy. The global conveyer belt takes oxygen-rich surface water and flushes it through the deep sea. Without this renewal, the dissolved oxygen in bottom sediments and waters would quickly be used up by the decay of organic matter. Anaerobic bacteria would take over decomposition, leading to a build up of hydrogen sulfide. Few benthic animals would survive such toxic conditions.
In the most extreme cases, a lack of downwelling may lead to mass extinctions. Paleontologists have suggested that 250 million years ago, deep circulation slowed nearly to a stop, and the ocean began to stagnate. Low oxygen, sulfide and methane-rich waters filled the ocean deeps and then spread onto the continental shelves, wiping out 95% of all marine species in the greatest extinction event in Earth history.

What is lactose endurance?Lactase endurance is the continuing interest of the lactase enzyme in adulthood. Since lactase's simplest feature is the digestion of lactose in milk, in maximum mammal species, the interest in the enzyme is dramatically decreased after weaning.
Thus it is clear that 40% of the human population evolve to tolerate lactose.

1.If a population has a birth rate of 0.07 and a death rate of 0.01, calculate the number of individuals added/subtracted from a population of 1,000 individuals in one year. 2.In a mark-recapture experiment, scientists tagged 300 birds in one month. Several months later, they returned and captured 500 birds. 75 of those birds had a tag on them. What is the size of the entire population
Answer:
1. The number of individuals added/subtracted from a population of 1,000 individuals in one year = 70/10 respectively (60 net).
2. The size of the entire population of birds = 2,000.
Explanation:
1. Population = 1,000
Birth rate = 0.07
Death rate = 0.01
Population Growth Rate = Birth rate + Net migration - Death Rate
= 0.07 = 0.01
= 0.06
The number of individuals added to the population = 70 (1,000 * 0.07)
The number of individuals subtracted from the population = 10 (1,000 * 0.01)
Therefore, the overall number added = 60 (70 - 10) or (1,000 * 0.06)
2. Number of birds tagged in one month = 300
Number of birds captured after several months later = 500 birds
Number of birds captured with a tag on them = 75
The proportion of tagged birds out of the captured = 75/500 = 0.15
The size of the entire population of birds = Number of birds tagged/Proportion of captured birds with a tag
= 300/0.15
= 2,000

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
Histones are a group of highly basic proteins that are mainly associated with deoxyribonucleic acid (DNA) in the nucleus of a living organism and are responsible for condensing it to chromatin.
Typically, acetylation of histone tails leads to relaxed packaging of the chromatin and increased transcription.
Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
