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:

F. Photosynthesis

Explanation:

The organelle pictured (a chloroplast) seems to be absorbing energy from the sunlight and that is included in the process of photosynthesis.

The carbohydrates (glucose) are formed by the process of photosynthesis in the chloroplast of the cell which then sent to the mitochondria for the production of ATP through glycolysis. Thus, the correct option is F.

Photosynthesis is the process of conversion of light energy (sunlight) into chemical energy (glucose). This process takes place in the chloroplast of plant cell where chlorophyll is present, this pigment (chlorophyll) is responsible for trapping the sunlight which is responsible for conduction of photosynthesis.

The products of photosynthesis (glucose) is sent to the mitochondria of cell for the production of ATP by the process of glycolysis. This ATP is then utilized by the cell in other cellular mechanisms.

Therefore, the correct option is F.

A. atmosphere

explanation: there is water vapor in the atmosphere that is considered to be part of the hydrosphere.

In an ecosystem, atmosphere is a sphere in  the Earth system  which is also part of the hydrosphere.

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Answer:

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:

Non Renewable Energy Impact on Environment

All energy sources have some impact on our environment. Fossil fuels—coal, oil, and natural gas—do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions.

Answer:

The four types of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.

Explanation:

So, your answer would have to be lipids, carbohydrates, and proteins, and nucleic acids. Fatty acids and carbon are not macromolecules.

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.

Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. They provide raw materials and resources for medicines and other purposes.

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.
