Which statement best describes how waves carry energy?

Answers

Answer 1
Answer:

A wave transfers energy by causing the particles of a medium to be set into vibration.

What is a wave?

A wave is a disturbance along a medium which transfers energy. We know that the particles that compose a medium tend to vibrate when a wave is in motion.

Hence, a wave transfers energy by causing the particles of a medium to be set into vibration.

Answer 2
Answer: In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. In water waves, energy is transferred through the vibration of the water particles.

2. A DNA molecule has the bases: A C G T T A. What set of bases will bond in a complementary way during replication? 3. Another molecule has the bases: A C G T T A. What mRNA strand will be made during transcription?

Answers

2. The base-pairing rule states that A can only pair with T and C with G.

So, T G C A A T

3. Messenger RNA is the complementary strand of the DNA with one exception: A pairs with U. Because RNA has a different sugar than DNA (ribose), thymine can no longer "Fit" with adenine and uracil is used instead. So, U G C A A U

Osmosis is the diffusion of water across a selectively permeable membrane in which water moves from a solution containing a low concentration of solute to what kind of solution?   A. a solution containing the same amount of solute
   B. a solution containing only the solute
   C. a solution containing a high concentration of water
   D. a solution containing a high concentration of solute

Answers

Answer:

D. a solution containing a high concentration of solute

Explanation:

Water alongside solutes tends to naturally move in the environment i.e. to and fro a cell. This movement is achieved when an osmotic gradient is formed during OSMOSIS. Osmosis is the movement of water from a region of low concentration of solute (high concentration of water) to a region of high concentration of solute (low concentration of water) through a semi-permeable membrane (usually the plasma membrane).

The difference in solution concentration between a cell and its external environment creates the OSMOTIC gradient. Water moves until an equilibrium is achieved in both the cell and environment.

State why detritivores are an important part of the ecosystem

Answers

The energy flow and biogeochemical cycles of the ecosystem depend heavily on detritivores as recyclers. Particularly in terms of the function of returning nutrients to the soil.

What is detritus food chain in ecosystem?

The kind of food chain known as a detritus food chain begins with decomposed organic matter. Microorganisms break down the decayed organic materials.

Detritivores, also called decomposers, are organisms that consume detritus, or dead organic materials.

Particulate Organic Material (POM), which is composed of tissues left behind when plants and animals die or molt and lose their skin or antlers, along with feces and germs, makes up detritus.

Therefore, detritivores are an important part of the ecosystem for energy flow and  biogeochemical cycles.

Answer: a schema

Explanation:

The term schema was first introduced in 1923 by developmental psychologist Jean Piaget. Piaget proposed a stage theory of cognitive development that utilized schemas as one of its key components. Piaget defined schemas as basic units of knowledge that related to all aspects of the world.

A schema is a cognitive structure that serves as a framework for one’s knowledge about people, places, objects, and events. Schemas help people organize their knowledge of the world and understand new information. While these mental shortcuts are useful in helping us make sense of the large amount of information we encounter daily, they can also narrow our thinking and result in stereotypes.

For example, when a child is young, they may develop a schema for a dog. They know a dog walks on four legs, is hairy, and has a tail. When the child goes to the zoo for the first time and sees a lion, they may initially think the lion is a dog as well. From the child’s point of view, the lion fits their schema for a dog.

Various types of schemas exist. These include object schemas, person schemas (behavior, appearance, preferences, personality), social schemas ( be respectful, don’t eat garlic before a date, pay for your dates movie tickets), self schemas( for example future doctor, smart, hates vegetables) roles schemas, event schemas (professionalism, business suit, portfolio, handshake) etc.
