Answer:
Irritability
Explanation:
Living things have been said to contain or possess certain characteristics that qualifies them to be "LIVING". These characteristics include; movement, respiration, growth, irritability, reproduction etc. The characteristics described in this question is IRRITABILITY.
IRRITABILITY is the ability of a living thing to respond to external or internal stimulus. In this case where Jamie drops a small amount of alcohol nearby a sample of pond water he collected, he notices that the small objects move towards the opposite side. This means that the objects are RESPONDING to a stimuli, which is the ALCOHOL in this case. Hence, irritability is the characteristics being tested.
in what ways does pollination in gymnosperms differ from pollination in angiosperms?
Answer:
In gymnosperms, pollination involves pollen transfer from the male cone to the female cone.
why do food chains in an ecosystem rarely contain more then five organisms
Why do food chains in an ecosystem rarely contain more than five organisms? ... Nutrients are lost from the ecosystem when organisms die. The conversion of food into growth by an organism is not very efficient. Energy is recycled by the decomposers back to the producers.
15. Briefly explain how the gel (or DNA fingerprint) is made after DNA has been amplified.
Answer:
Like the fingerprints that came into use by detectives and police labs during the 1930s, each person has a unique DNA fingerprint. Unlike a conventional fingerprint that occurs only on the fingertips and can be altered by surgery, a DNA fingerprint is the same for every cell, tissue, and organ of a person. It cannot be altered by any known treatment. Consequently, DNA fingerprinting is rapidly becoming the primary method for identifying and distinguishing among individual human beings. DNA fingerprints are also useful in several applications of human health care research and for diagnosis of inherited disorders. DNA fingerprinting is often used in the justice system to link suspects to biological evidence and solve paternity cases.
Explanation:
DNA sample: A DNA sample that will be examined must first be gathered. DNA extraction: Using the lysis process, DNA is then extracted from the sample.
What is DNA fingerprint?Restrictions endonucleases:The DNA fragment is cut at a particular place by a specific restriction enzyme.
Alec Jeffrey, a British biologist, created the DNA fingerprinting technique in 1984 after noticing that some highly variable DNA sequences, or minisatellites, that are repeated inside genes but do not affect their activities.
In DNA fingerprinting, a gel-like fluid is used to distinguish between DNA molecules that move at various speeds. A DNA molecule that is huge moves slowly, whereas a DNA molecule that is little moves quickly.
Therefore, DNA molecules are divided in gel electrophoresis according to size. When DNA molecules are divided into distinct sizes, bands of DNA are created.

Each cell has a structure that separates the inside of the cell from.the environment. What cell is this?
Answer:
Either the cell wall or the cell membrane.
Explanation:
All cells have cell membranes which line the outside of the cell, and some cells have cell walls, which also line the outside of the cell. Since all cells have cell membranes I am inclined to believe that the correct answer would be cell membranes.
What does the process of cell respiration provide for cells?
Answer:
Cells do cellular respiration to extract energy from the bonds of glucose and other food molecules. Cells can store the extracted energy in the form of ATP.

Explanation:
A famous celebrity has an extreme security system for their estate. The security system includes sensors in the ground as well as on the sides of the buildings. A loud truck drives down the road entering the estate. There is a sensor in the ground and another on the side of the security guard’s shed. If both sensors are 100m from the truck, which sensor will pick up the noise of the truck first and why?
A.
Guard Shed - The sensor on the security guard’s shed will detect the sound first because the sound is traveling through the air and sound will travel fastest through a gas.
B.
Ground - The sensor in the ground will detect the sound first because the sound is traveling through the dirt and sound will travel fastest through a solid.
C.
Same time - Because the sound is traveling through both the ground and the air at the same time, it will reach both the shed and the ground sensor at the same time.
D.
Neither sensor - 100m is too far for the sound to travel. Neither sensor will pick up the sound of the truck until it is closer to them.
Answer:
B. Ground - The sensor in the ground will detect the sound first because the sound is traveling through the dirt and sound will travel fastest through a solid.
Explanation:
Sound wave is an example of mechanical wave, which means sound waves require a medium to travel through. However, how fast a sound travels is dependent on the kind of medium it travels through. Sound travels fastest via a SOLID medium, then liquid and slowest through gases.
According to this question, sensor in the ground and side of the security guard’s shed were placed in an estate owned by a famous celebrity. A loud truck, then, drives down the road entering the estate.
Based on the principles of sound eaves movement, the sound from the truck will be picked by the sensors in the GROUND first because the sound is traveling through the dirt and sound will travel fastest through a solid.
Composites are made from
a. layers of wood glued together in sheets
b. two or more plastics mixed together to make a new plastic
c. two or more materials mixed together that chemically mix into a new material
d. two or more materials mixed together to make a stronger material but the individual components remain visible
GREETINGS!
D is the answer
Explanation:
A composite is made by combining two or more other materials so they improve one another but keep distinct and separate identities in the final product. So a composite isn't a compound (where atoms or molecules bind together chemically to make something quite different), a mixture (where one material is blended into another), or a solution.

Earth began as a mixture of about 90% stony, olivine-rich material and about 10% iron metal, just like the composition of chondritic meteorites. Soon after its formation the interior of the Earth is thought to have become very hot. What was the result of this increase in heat? A) The iron melted and collected in the interior of Earth to become its core. B) The olivine remained behind, becoming the mantle and the melted iron became the core. C) Both the olivine and iron melted and as they later solidified, became the mantle and the core. D) The olivine became the crust and the iron, melting, defended into the earth to become the core.
Answer: D. The olivine became the crust and the Iron melting defended the earth to become the core.
Explanation:
Earth was formed after it has went through a molten stage that led to the heavy materials sure as Iron metal moving inward to form the core, and the light materials moves toward the surface to form the crust.
The heat for the melting came from meteorite impacts which is usually very hot, the moon's impact, and the decay of radioactive elements.
Geological activity on the earth is driven from this initial source of heat at the earth's formation until now.

Why is volume measured in both cubic meters or cubic centimeters and liters
Answer:
The base units of length and volume are linked in the metric system. By definition, a liter is equal to the volume of a cube exactly 10 cm tall, 10 cm long, and 10 cm wide. Because the volume of this cube is 1000 cubic centimeters and a liter contains 1000 milliliters, 1 milliliter is equivalent to 1 cubic centimeter.
