It produces pollen.​

Answer:

Soil are tiny bits of substances that contains animal and plants parts as well as nonliving matter such as rocks. They are compressed together by years of new layers of whatever sitting on top of it (New layers of soil, etc). Erosion also assists in the forming of soil as it may take layers of soil from a forest to another for example.

Answer:

a. glycolysis

Explanation:

I'm really unsure about this but in glycolysis if there is no oxygen, there is a process called fermentation. Fermentation is an anaerobic process and is used when our body lacks in oxygen

Answer:

With the help of warmth, oxygen, and good food from the soil, the seed will  open and sprout out. Once the leaves and roots will grow, the plant can go through the process of photosynthesis, the process that plants use to breathe and to make food using sunlight, during photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Explanation:

Answer:

The cells that make up the digestive, muscular, skeletal, reproductive, and excretory systems all need oxygen from the respiratory system to function, and the cells of the respiratory system as well as all the other system bneed nutrients and must get rid of metabolic wastes.

Answer:

1. Slash and Burn agriculture refers to a technique of farming that requires plants in a forest or woodland to be decimated to create a cultivable expanse of land.

Some of these plants are usually homes to wild chimpanzees. The more they are cut down, the deeper into the forests they would migrate, that's if they ever find a place like it.  

2. When compared to the other primates such as monkeys, baboons, etc their larger body size, puts them at a disadvantage. This is because when they are placed in a restricted space, they need more food which in turn translates to increased height and weight.

Answer:

1. Nitrification occurs when soil microbes convert ammonium into nitrate. Much of the overlap between the carbon cycle and the nitrogen cycle occurs in the soil, in processes conducted by soil microbes. Microbes break down nutrients, build new compounds for their own growth, and eventually die.

The second question im not sure sorry- the positive and negative one ;(

3. Many human activities have a significant impact on the nitrogen cycle. Burning fossil fuels, application of nitrogen-based fertilizers, and other activities can dramatically increase the amount of biologically available nitrogen in an ecosystem. As nitrogen makes up 78% of the atmosphere, there is no shortage of it – it just isn't in a form plants and animals can use.

4. Carbon makes its way through living things as carbon-based compounds, like energy molecules, fats and proteins, eventually cycling its way back into the atmosphere. Nitrogen is mainly found in the atmosphere as well and enters the ecosystems as nutrients for plants. Water, nitrogen and carbon cycles. Carbon moves from the atmosphere and back via animals and plants. Nitrogen moves from the atmosphere and back via organisms. Water moves on, above, or below the surface of the Earth.

5. Carbon cycle, Nitrogen cycle, Nutrient cycle, Oxygen cycle, Phosphorus cycle, Sulfur cycle, Rock cycle, Water cycle.

6. Wind, water, and ice erode and shape the land. Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of earth's plates slowly reconfigures oceans and continents. Each one of these processes plays a role in the Arctic and Antarctica.

Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Earth's surface is the only habitat available to the human race. Understanding the processes by which that habitat has been created and continually altered is important to determine the causes of environmental degradation.

The event that is associated with convergent boundaries is ; ( A ) Formation of  Island chains

Island chains also known as Archipelago are a group of Islands evenly distributed in lakes, oceans and rivers within a defined area. with the Islands sharing a convergent boundary with each other.

Examples of an Island chain is the Mariana Islands and Japan where the chain of Islands share convergent boundaries.

Hence we can conclude that the event that is associated with convergent boundaries is the formation of Island chains .

1. Energy is often considered the “Fuel of Life”. Primarily, it is needed for maintaining basic

metabolism (maintenance energy). Any excess is then used for production of meat (growth)

and/or eggs (production). Fed too much energy, hens become overweight (excess growth)

leading to poor production. If fed too little energy, hens begin using protein to meet their basic

maintenance needs and egg production may be compromised. As is the case with most things

in life, balance is the key. This article is an attempt to provide a flock manager with some tools

to use when making decisions on feeding energy to a breeder flock. Some of the research

cited is not current and is in no way intended to be anything more than an example of the

thought processes that may be helpful when making difficult decisions about feeding.

Energy is essential to meet our most basic needs: cooking, boiling water, lighting and heating. It is also a prerequisite for good health – a reality that has been largely ignored by the world community.

2. Coal and diamond are two examples of carbon allotropes, where the carbon atoms are bonded together in different configurations. These structural differences result in very different material properties, such as hardness.

On its own, carbon cannot form diamonds under the surface of the Earth. Both coal and diamond are made primarily from carbon, but their chemical structures are significantly different. Coal is formed from highly impure carbon that often contains elements like oxygen, selenium, hydrogen, nitrogen and sulfur.
