COMPARE THE LOUDNESS OF SOUND WAVES THAT ARE IN PHASE WHEN THEY INTERFERE WITH THE LOUDNESS OF SOUND WAVES THAT ARE OUT OD PHASE WHEN THEY INTERFERE

Answers

Answer 1

Answer:

Loudness of a sound relates the intensity of any given sound to the intensity at the edge of hearing.

The loudness of sound waves that are in phase will be twice as loud as they would be by themselves, if they are out of phase, a beat will be produced, or maybe a neighborhood of no sound at all.

Intensity of sound

The intensity of a sound is the power of the sound in Watts divided by the area the sound covers in square meters. The loudness of a sound relates the intensity of any given sound to the intensity at the edge of hearing.

Thus, the sound waves that are in phase will be twice as loud as they would be by themselves,if they are out of phase, the beat will be produced.

Answer 2

Answer: The loudness of sound waves that are in phase (experiencing constructive interference) will be twice as loud as they would be by themselves. If they are out of phase, a beat will be produced, or even an area of no sound at al

Salinization increases the concentration of _______ in soil.a. plants
b. nutrients
c. salt
d. water

Answers

Answer: The correct answer for the blank is - c. salt.

Salinization can be described as a process of increasing salt content in any body (such as water body, soil).

Soil Salinization thus increases the concentration of salt in the soil (in the form of water soluble salt).

Thus, option C) is the right answer.

Salt, its the process of increasing the salt content.

Imagine that a scientist discovers a new, flying species of mammal that resembles a winged rabbit. what can the scientist say about this organism? if molecular sequence data show that bats and this new species share a common ancestor not shared by other mammals, the wings of these two species would be considered analogous. if molecular sequence data show that bats and this new species do not share a common ancestor not shared by other mammals, the wings of bats and this new species would be considered homologous. no data could support or disprove the hypothesis that the wings of bats and the new species are homologous. if molecular sequence data show that bats and this new species share a common ancestor not shared by other mammals, the wings of these two species would be considered homologous. without any further information, the scientist can say that bat wings and the wings of this new species are homologous.

Answers

I think the scientist would say this about the organism; that if molecular sequence data show that bats and this new species share a common ancestor, the wings of these two species would be considered homologous. Homologous structures are structures which have similar ancestries and common traits but maybe not have the same function in an organism. Examples are the arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin, are all homologous structure.

A critical feature of the plasma membrane is that it is selectively permeable. this allows the plasma membrane to regulate transport across cellular boundaries--a function essential to any cell's existence. how does phospholipid structure prevent certain molecules from crossing the plasma membrane freely?

Answers

The structure of the plasma membrane makes it selectively permeable, enabling it to regulate the transport substance into and out of the cell, such as
- small, non polar molecules are hydrophobic
- Polar molecules and ions are hydrophilic
- Polar molecules and ion usually pass with the help of protein

hope this helps

The factor which makes the permeability of the plasma membrane a main reason for the cells existence is that this condition makes the cell a to take in important required substances and throw out waste. Thus, the life of the cell is based the fact that the plasma membrane is selectively permeable.

Further Explanation:

Eukaryotic cells are the cells which have membrane-bound organelles, membrane-bound nucleus, and several chromosomes. They have a true nucleus and have some similarity with prokaryotic cells like plasma membrane, cytoplasm, and ribosomes.

Plasma membrane is selectively permeable as they allow only certain molecule to pass through them. This permeability is dependent on many factors one of them being the need of the molecule by the cell. The membrane of the cell is made up of following components;

1. Phospholipid bilayer

2. Transmembrane proteins

3. Interior protein network

4. Cell surface markers

Out of these components the one responsible for maintaining the movement of the chemicals or molecules across the membrane is the phospholipid bilayer and the transmembrane proteins. The major component which acts as an permeability barrier is the phospholipid bilayer.

Which three components are common to all amino acids?

Answers

An amino acid is usually considered as the building block of a protein, is a constituent that plays a significant function in the body. The amino acids are required for essential activities like the synthesis of neurotransmitters and hormones and manufacturing of proteins.

There are different kinds of amino acids found, however, all these amino acids possess three constituents, which are common to all the amino acids. These are an amino group, a carboxyl group, and an R group.

the 2o amino acids vary structure by the r-group , otherwise all amino acids are in the same structure, all amino acids have carboxyl group , amino group and a r-group and a hydrogen which are all bonded to a central carbon,
