Answer:

Since electromagnet waves do not need a medium they can travel through space. Sound waves can't travel through space because they need a medium.

Explanation:

The satellite uses electromagnetic waves instead of sound waves these types of waves do not require any medium for the transmission of the information.

The types of electromagnetic waves that are used by satellites are known as radio waves. These waves are utilized in order to carry out satellite signals with a speed of 3000,000km/sec.

Electromagnetic waves facilitate the required amount of speed and characteristics which ease the transmission of information required by the satellites. Radio waves are traveling through the vacuum of space with the fastest speed at which the information via the satellite can be transmitted. Radiowaves are also used for spacecraft communications as well.

Therefore, the satellite uses electromagnetic waves instead of sound waves these types of waves do not require any medium for the transmission of the information.

If I were you, I would make my hypothesis something like:

"If the vegetation type is a savannah/woodland, then it will support the highest abundance of life."

Explanation:

I know that hypothesis can be tricky to write at first, but if you turn the research question into a sentence, then you can write your hypothesis. Best of luck with your experiment.

Answer:

During cellular respiration glucose and oxygen are converted into carbon dioxide and water and the energy is transferred to ATP.

Explanation:

The climate change increases the overall temperature of the earth, glaciers can melt into the ocean. The spheres involved cryosphere and hydrosphere. Thus option A is correct.

Cryosphere is defined as solid precipitation, snow,  sea ice, lake and river ice, icebergs, glaciers and ice caps, ice sheets, ice shelves, , and seasonally frozen ground are all components of the Earth's climatic system.

It can also be defined as the area of the earth's surface marked by the presence of water.

Hydrosphere is defined as the total mass of water on, beneath, and above the surface of a planet, minor planet, or natural satellite.

It can also be defined as the component of the Earth made up of all liquid water.

There are basically three types of hydrosphere.

Climate change is defined as the long-term temperature and weather pattern shifts These changes could be natural, such as oscillations in the solar cycle.

Thus, the climate change increases the overall temperature of the earth, glaciers can melt into the ocean. The spheres involved cryosphere and hydrosphere. Thus option A is correct.

Answer:

Time, t = 9.62 secs.

Explanation:

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

[tex]Speed = \frac{distance}{time}[/tex] ....equation 1

Making time the subject formula;

[tex]Time = \frac{distance}{speed}[/tex] .....equation 2

Given the following data;

Distance = 100m

Speed = 10.4m/s

Substituting into equation 2;

[tex]Time = \frac{100}{10.4}[/tex]

Time, t = 9.62 secs.

Answer:

If ATP and NADPH are already used up at night , the production of glucose will stop.

Explanation:

IMPORTANCE OF ATP AND NADPH -: To temporarily store energy, the light-dependent reactions generate ATP and either NADPH or NADH. In light-independent reactions, these energy carriers are used to drive the energetically unfavorable mechanism of "fixing" organically inorganic CO2.

ATP is the molecular energy "currency" in biological systems. All energy produced by living organisms' cellular respiration must end up being used as ATP to power it. NADPH is a hydrogen carrier molecule reduced by NADP (Nicotinamide Adenine Dinucleotide Phosphate). While the light-dependent reactions take place, energized electrons hop on to electron carriers excited by photon energy from the sun (On Photosystem 2) and finally get to Photosystem one.

If ATP and NADPH are already used up at night, the fixation of carbon dioxide into glucose will halt. In other words, the light-independent reaction of photosynthesis will stop.

There are essentially 2 reactions in photosynthesis:

In the light-dependent reaction, radiant energy is used to excite electrons chlorophyll molecules while electrons in water replace the excited electrons. ATP and NADPH are generated in the process.

The ATP and NADPH produced during the light-dependent reaction of photosynthesis are essential for the reduction of carbon dioxide into glucose in the light-independent reaction.

Hence, unless the light-dependent reaction takes place to make ATP and NADPH available, there is no other way to produce the precursors for the fixation of carbon dioxide into glucose.
