choke. The water has gotten into the person's
windpipe. Which part of the upper respiratory
system is supposed to prevent this?
larynx
nasal cavity
pharynx
nose
A flap of tissue called the epiglottis sits over the top of the trachea. This flap blocks food and drink from going down into the trachea when you swallow. But in some cases, food or drink can enter the trachea. It may go down as you swallow.

Study the graph below. At what depth does the thermocline begin?
A line graph relating ocean depth to water temperature. At 0 meters, temperature is approximately 27°C. At 100 meters, temperature is approximately 24°C. At 200 meters, temperature is approximately 11°C. At 300 meters, temperature is approximately 8°C.

0 meters
100 meters
200 meters
300 meters
Answer: 100 meters
Explanation:
The thermocline begins at 100 meters of depth. Thermocline is a transition oceanic water layer between deep and surface water in which water temperature decreases rapidly with increasing depth. From the given graph it cam be seen that at 100 meters the thermocline begins such that the temperature drops from to.

Explain the impact of a force on wave movement on land.
Answer: Waves are important for building up and breaking down shorelines. Waves transport sand onto and off of beaches, transport sand along beaches, carves structures along the shore. The largest waves form when the wind is very strong, blows steadily for a long time, and blows over a long distance.
The wind could be strong, but if it gusts for just a short time, large waves won’t form. Wave energy does the work of erosion at the shore. Waves approach the shore at some angle so the inshore part of the wave reaches shallow water sooner than the part that is further out. The shallow part of the wave ‘feels’ the bottom first. This slows down the inshore part of the wave and makes the wave “bend.” This bending is called refraction.
Wave refraction either concentrates wave energy or disperses it. In quiet water areas, such as bays, wave energy is dispersed, so sand is deposited. Areas that stick out into the water are eroded by the strong wave energy that concentrates its power on the wave-cut cliff.
A wave-cut platform is the level area formed by wave erosion as the waves undercut a cliff. An arch is produced when waves erode through a cliff. When a sea arch collapses, the isolated towers of rocks that remain are known as sea stacks.
Wave Deposition
PictureRivers carry sediments from the land to the sea. If wave action is high, a delta will not form. Waves will spread the sediments along the coastline to create a beach. Waves also erode sediments from cliffs and shorelines and transport them onto beaches.Beaches can be made of mineral grains, like quartz, rock fragments, and also pieces of shell or coral. Waves continually move sand along the shore and move sand from the beaches on shore to bars of sand offshore as the seasons change. In the summer, waves have lower energy so they bring sand up onto the beach. In the winter, higher energy waves bring the sand back offshore.Some features form by wave-deposited sand. These features include barrier islands and spits. A spit is sand connected to land and extending into the water. A spit may hook to form a tombolo. Shores that are relatively flat and gently sloping may be lined with long narrow barrier islands. Most barrier islands are a few kilometers wide and tens of kilometers long.In its natural state, a barrier island acts as the first line of defense against storms such as hurricanes. When barrier islands are urbanized, hurricanes damage houses and businesses rather than vegetated sandy areas in which sand can move. A large hurricane brings massive problems to the urbanized

In what phase of meiosis is DNA replicated?
Answer:
During prophase I, the chromosomes condense and become visible inside the nucleus. Because each chromosome was duplicated during the S phase that occurred just before prophase I, each now consists of two sister chromatids joined at the centromere.

1. the process by which organisms produce new organisms of the same type ____________________
Answer:
Reproduction.

A biological macromolecule is made up of glycerol and fatty acids. Based on this information, what type of molecule is this? Choose 1 answer: Choose 1 answer: (Choice A) A Nucleic acid (Choice B) B Carbohydrate (Choice C) C Protein (Choice D) D Lipid
Answer:
D. Lipids
Explanation:
A biological molecule that is made up of glycerol and fatty acids is known as Lipid. Thus, the correct option is D.
What are Biological macromolecules?Biological macromolecules may be defined as those large and organic molecules that are important to biophysical processes. It includes carbohydrates, lipids, proteins, and nucleic acids.
Nucleic acids are derived from a pentose sugar, a phosphate group, and a base. Protein is derived from their monomers known as amino acids. Carbohydrates are derived from monosaccharides units such as glucose. It includes carbon, hydrogen, and oxygen.
Triglycerides are a simple form of lipids that are constructed with the help of one molecule of glycerol while three molecules of fatty acids.
Therefore, a biological molecule that is made up of glycerol and fatty acids is known as Lipid. Thus, the correct option is D.

Why is the use of stem cells to produce new specialized cells, which can replace a body's damaged cells and cure disease, creating a controversy?
Answer:
human embryonic stem cells are obtained from embryos, thereby they are subject to ethical, religious, political and legal considerations
Explanation:
Human embryonic stem cells (HESCs) are pluripotent undifferentiated cells derived from blastocyst-stage embryos, which have the ability to produce any type of somatic cells. HESCs are obtained in vitro from embryos that are 5-6 days old. These cells are valuable tools in research in order to understand the genetic and physiological mechanisms of human development, as well as to develop treatments against diseases. The use of embryonic stem cells in research is controversial because these techniques involve the destruction of human embryos, and there are people who consider human life begins with the formation of the diploid zygote after fertilization, thereby raising the debate if a human embryo can be regarded as a human being.

How do you think that wearing personal protective equipment helps to protect us from contracting airborne diseases?
Answer:
Airborne transmission may occur if patient respiratory activity or medical procedures generate respiratory aerosols. These aerosols contain particles that may travel much longer distances and remain airborne longer, but their infective potential is uncertain. Contact, droplet and airborne transmission are each relevant during airway manoeuvres in infected patients, particularly during tracheal intubation.

Why did Mendel study pea plants?
Answer:
Pea plants were fundamental in allowing him to understand the means by which traits are inherited between parent and offspring. He chose pea plants because they were easy to grow and could be bred rapidly and had many several observable characteristics like petal color and pea color. Mendel used a tall plant and a small plant expecting a medium plant to com out. That was not the case one tall plant came out and so did 3 small ones. This is because of genetics. And the genetic chart showing what the percents are.

Answer:
Tube 1: Pepsin
Tube 2:Albumin
Explanation:
The tubes that contain protein are TUBE 1 : PEPSIN and TUBE 2 : ALBUMIN
Pepsin contains inactive protein called Zymogen also called pepsinogen.
Albumin is the single most abundant protein which is produced in the liver.
Starch does not contain protein but sugar which yields Carbonhydrate.
Tube 4 : contains water which is also a form of nutrient different from protein.
Therefore, the tubes that contain protein ARE tube 1 and tube 2 : PEPSIN and ALBUMIN.
