When the sound wave is converted to a digital signal, it can be stored and transmitted by a computer.

A wave is defined as a disturbance in a medium that carries energy without net movement of particles which may take the form of elastic deformation, variation of pressure, electric or magnetic intensity, electric potential or temperature.

When a sound wave is converted into a digital signal that can be stored and transmitted by a computer. It allows us to download, play and stream music from our smartphones. Analog signals can be converted to digital signals where modern computers are controlled by digital, not analog signals.

Thus, when the sound wave is converted to a digital signal, it can be stored and transmitted by a computer.

Answer:8

Explanation:

Number of chromosomes in each body cell is 8.

A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones.

Moreover, chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).

Therefore, passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

The velocity of a river decreases  when it enters another body of water.

A river's velocity abruptly drops as it reaches a lake or ocean, for example, and the stream deposits its silt in a deposit known as a delta.

The channel's form, the slope the river travels down, the volume of water in the river, and many other factors affect a river's velocity.

Answer:

A greenhouse effect is when a planets atmosphere gets thicker and warms

Explanation:

As a planet with water's parent star gets brighter every million years,  The amount of evaporation increases. these are called greenhouse gasses. greenhouse gasses include water vapor and Carbon. This is why  Venus is a burning hell. it was once like earth, but the sun kept getting brighter and brighter, causing clouds to form all over the rock, trapping in more heat, and making it far to hot for even metal. One day this will happen to earth, as well. this is why we have global warming. It can be caused by Co2 from earth's inhabitants and water vapor from it's vast oceans.

Small and Family Farms. More than 90 percent of farms in the U.S. are classified as small, with a gross cash farm income of $250,000, or less. These farms, most of which are family-owned and operated, confront considerable challenges due to current trends, such as increased movement into cities, an aging population, farm consolidation, and changing weather patterns.

Explanation:

Conduction is a heat transfer method. The heat passes by direct contact between two objects. The heat will go from the object with the higher temperature to the one with the lowest one. We call this temperature gradient. If we analyze the molecular aspect of conduction, we can see that the molecules with higher temperatures have more energy so, they move more. These molecules will collide with the molecules of the other object transferring their energy. As a result, heat passes from the hottest object to the cooler one till the two substances are at the same temperature, there is thermal equilibrium.

Answer:

In photosynthesis, light gives energy to the electron moving through the electron transport chain. So its C.

Explanation:

In the photosynthesis of plants, the light gives energy to the electrons passing through the electron conveyor chain. This Light energy is then transformed to chemical energy, which creates ATP; an energy storehouse molecule, and NADPH, a decreased electron transport. Moreover, light energy is utilized to elevate protons across a membrane to compose a proton-motive force.

Answer:

It occurs in organisms because an organism with a beneficial trait/mutation have a higher chnace of surviving compared to organisms that do not. So the organsims that do survive pass on their genes to the next generation, and the bext generation will pass on those genes to the generation after and so on. But all the organisms that do not possess a beneficial trait/mutations will not survive, therefore they cannot reproduce and pass on those genes to their offspring. This means that most of the population will posses that trait/mutation.

Example: Spotted moths camouflage with bark so they are seen by predators and eaten. Black moths are easily seen by predators and are eaten. Spotted moths then pass on their genes to the next generation of moths.

Answer:

Explanation:

Genes contain specific instructions for how to make proteins within the body.

Epigenetic changes are generally heritable genetic changes that are due to environmental factors, which work by turning genes that already exist in the body 'on' or 'off' depending on these factors.

Meiosis produces gamete cells. This is usually a total of 4 gamete cells which are all part of producing everything required in the reproductive process.

exposure to extreme heat is probably the most likely cause of mutation for E. Coli as it needs a steady 36–40°C for survival.

Changes to body cells affect cell division. This is because genetic mutations cause cells that are designed for normal cell growth to greatly increase which can throw the system off and cause many problems.

Answer:

1.5m/s

Explanation:

Using the formula;

Speed (m/s) = distance (metres) ÷ time (seconds)

According to the information provided in this question, Heather and Matthew spend 60seconds to travel a distance of 90 metres. This means that t = 60s, d = 90m

Hence,

Speed = 90/60

Speed = 3/2

Speed = 1.5m/s.
