4 typhoon means a wind threat that has the high speed of wind can attack 118-184 km/h.

Typhoon is defined as a tropical cyclone with a maximum wind of 34 knots or higher. A tropical cyclone with a maximum wind of fewer than 34 knots is called a tropical depression. The difference between the two types of tropical cyclones is just if the maximum wind is less than or above the threshold of 34 knots.

Tropical cyclones (Typhoon ) form between 5 and 30 degrees North latitude that move toward the west. Sometimes the winds in the middle and upper levels of the atmosphere change and move the cyclone toward the north and northwest direction.

So we can conclude that a typhoon is a tropical cyclone that includes a maximum wind of 34 knots or maybe higher.

Answer:

Ptolemy

Explanation:

Ptolemy is the earliest earliest astronomer and mathematician in the list who lived and worked in the second century AD. Nothing is known about his personal life but his scientific work is well known.

He made his observations using naked eyes. In his opinion, the Universe is ''a set of nested, transparent spheres, with Earth in the center.''(Khan Academy). His argument was that the Moon, Mercury, Venus, and the Sun were all revolving around around Earth.

Although Ptolemy made significant contributions in Astronomy but he was wrong in positing that the earth did not move at all. This is inconsistent with our present day knowledge about the celestial bodies. Also, his work missed out other planets that were yet to be discovered then such as Uranus, Neptune, Pluto etc.

1. anterograde transport- movement down the axon away from the soma

2. slow anterograde transport- movement of enzymes and cytoskeleton components down the axon to renew worn-out axoplasmic components

3. fast retrograde transport- returns used synaptic vesicles and other materials to the soma

4. fast anterograde transport- movement of enzymes and small molecules toward that distal end of the axon

5. axonal transport- two-way passage of proteins, organelles, and other materials along an axon.

What does the word "axon" mean?

The component of a nerve cell (neuron) known as the axon, also known as the nerve fiber, is responsible for carrying nerve impulses away from the cell body. Typically, a neuron contains one axon that connects it to other neurons, muscle cells, or glandular cells. Some axons may extend all the way from the spinal cord to the tip of a toe, for instance.

Axonal transport, which is thought to be crucial for nerve growth, function, and survival, is the process by which motor proteins actively travel microtubules to transfer a variety of payloads, such as organelles, from one end of the axon to the other.

Hemolytic jaundice, also known as hemolytic anemia, is the type of jaundice seen in adults that is the result of increased destruction of red blood cells.

Jaundice is a medical condition characterized by yellowing of the skin and eyes, caused by high levels of bilirubin in the blood. Hemolytic jaundice occurs when there is an accelerated breakdown of red blood cells (hemolysis) in the body. This increased destruction can be due to various factors, such as autoimmune disorders, certain medications, infections, or inherited conditions like sickle cell disease or hereditary spherocytosis. As red blood cells break down, bilirubin, a yellow pigment produced from the breakdown of hemoglobin, is released into the bloodstream. Elevated levels of bilirubin lead to the characteristic yellowing of the skin and eyes seen in jaundice.

Among the different types of jaundice seen in adults, hemolytic jaundice specifically arises from increased destruction of red blood cells, resulting in the accumulation of bilirubin and subsequent yellowing of the skin and eyes.

The non-oxidative stage of the pentose phosphate pathway produces substances that are intermediates of glycolysis.

Glycolysis is the method of dividing glucose to produce energy. It generates two pyruvate particles, ATP, NADH, and water.

The process occurs in a cell's cytoplasm and therefore does not entail oxygen. It can be found in aerobic and anaerobic organisms.

Since it is utilized by nearly all organisms on Earth, it was most likely one of the first metabolic pathways to evolve.

The non-oxidative phase of the pentose phosphate pathway generates glycolysis adducts.

Answer:

Bears and lizards are more closely related.

Explanation:

The chart shows the branches of the species. The relativity of each species to each other shows how closely related they are.

organisms that are placed close to each other and have a nearly common ancestor have some similarities, so the bear and the lizard are closer to each other than the newt because they are closely present in the cladogram.

The cladogram is the diagrammatic representation of the animals and shows how the organisms have evolved and their special traits. This cladogram explains how the species show commonness and difference, such as the bear and the chimpanzee, which are both derived from the common mammal ancestor.

From the common amneote ancestor, the lizard, bear, and chimpanzee are descended, so they all have the traits of the amneote. From a common tetrapod ancestor, the newt, the lizard, the bear, and the chimpanzee are derived, and all have some characteristic of the tetrapoda.

Hence, the bear and the lizard are closer to each other than the newt because they are both present closely in the cladogram.

The developments and discoveries made during the industrialization period have had a profound impact on science and medicine. They have led to many new treatments and cures for diseases, as well as many new ways of understanding the world around us.

There have been many developments and discoveries in science and medicine that have been attributed to industrialization. One of the most important ones is Salk's development of a vaccine that could prevent polio. The vaccine is made by taking a weakened virus and injecting it into a person's body. The body's immune system then produces antibodies that can fight off the virus if it ever enters the body again.

Another important discovery was Pasteur's discovery that disease is spread by bacteria. He proved this by using a microscope to look at samples of water that had been taken from different sources. He found that the water from some sources contained bacteria, while the water from others did not. This led him to conclude that the bacteria were the cause of the disease.In addition to these discoveries, there were other important ones that were made during this time. Curie's development of the process of pasteurization, for example, was an important one. Pasteurization is a process by which food is heated to a temperature that kills harmful bacteria. This process is still used today in many food production processes.

Finally, Jenner's discovery of a medium for growing and identifying bacteria was also an important one. This discovery led to the development of many new medical treatments that have helped to save countless lives.

Factors such as initial velocity, launch angle, distance to rescue ship, and acceleration due to gravity needed to be considered, and unique circumstances such as the assumption of no external factors and level surface were considered in predicting the height of the flare.

To make the prediction, several factors needed to be considered, such as the initial velocity and launch angle of the flare, the distance to the rescue ship, and the acceleration due to gravity.

These factors were used to calculate the time it would take for the flare to reach the rescue ship and the height of the flare when it is directly above the ship.

Additionally, some unique circumstances needed to be considered, such as the assumption that the flare was launched from a level surface and there were no external factors affecting its trajectory, such as wind or air resistance.

These assumptions allowed for a simplified calculation of the height of the flare and may not necessarily reflect the actual height in a real-world scenario.

It's also important to note that in a real-world rescue situation, the flare's trajectory and height could be affected by various environmental factors.

And the rescuers would need to take these factors into account when determining the flare's location and the direction of the rescue operation.
