Answer:

Satellites

Localised instruments.

Explanation:

Satellites are technological device that is use to provide information from.some region of the Earth's biosphere like oceans , clods, lands e.t.c.It uses radar or optical sensor to capture images on the Earth. Satellite orbits round bigger objects.

Localised instruments are technological devices that is also use to provide information about the Earth's biosphere.

Answer:

Water is least dense at 0°C (freezing point)

Answer:

Independent Variable - Amount of Light;

Dependent Variable - Plant Growth;

Controlled Variables - temperature, soil, container, and humidity

Explanation:

Independent Variable - Amount of Light;

Dependent Variable - Plant Growth;

Controlled Variables - temperature, soil, container, and humidity

1. Plants need light for it growth and development. By studying photosynthesis and chlorophyll one can  recognizes two factors: measure of light and development of a plant.  

The adjustment in light influences the development of a plant. Both the two factors are measurable.  

Cause-Independent Variable: measure of light  

Impact Dependent Variable: development of plant  

2. Plants have stems that become upward and roots that become descending. Become familiar with geotropism.  

Answer:

The rose experiment is not a specific experiment but refers to a general example used to explain the concept of variables in an experiment. In this example, let's say we want to study the effect of fertilizer on the growth of roses.

The independent variable in this experiment is the fertilizer. It is the variable that is manipulated or changed by the experimenter. In other words, the experimenter decides how much fertilizer to apply to each group of roses.

The dependent variable in this experiment is the growth of the roses. It is the variable that is being measured and affected by the independent variable. In this case, the experimenter measures the height, number of leaves, and number of flowers for each group of roses, and this data is used to determine if the fertilizer had any effect on the growth of the roses.

Therefore, in the rose experiment, the independent variable is the amount of fertilizer applied to each group of roses, and the dependent variable is the growth of the roses, measured by their height, number of leaves, and number of flowers.

Answer:

The most generally accepted explanation for fossil fuel production is that, over time, fossil fuel was formed from declining organic matter. Organisms died and were buried in the earth millions of years ago. The carbonaceous substances within the humans, subjected to the high temperature and pressure below the earth's surface, were converted into types of fossil fuel such as coal and oil.

Answer:

Phototropism is an important light response in plants. Positive Phototropism leans towards the light and negative Phototropism growth away from the light.

A. An experience or period in the author’s life.

Explanation:

A memoir is a story about an experience in someones life, but it has to be factual. A memoir can not be based on fiction, it has to be real and nonfictional.

Memoirs are usually told in first person, as it is recounting the occurrences that happened in ones life. It is different from an autobiography, as autobiographies usually focus on the whole lifespan of a person, while a memoir focuses on one topic or event that happened.

Memoirs also usually focus on personal growth throughout the writing, are truthful and keep track of the persons goals and influences.

Explanation:

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 .

Explanation:

Answer:

The correct answers are "heterozygous", and "homozygous dominant".

Explanation:

Galactosemia is a condition where people are not able to process the sugar galactose. People with this condition have one gene mutated, which does not allow the proper synthesis of the enzyme that breaks down galactose. Galactosemia is inherited as an autosomal recessive genetic condition, therefore, only children that are homozygous recessive develop the condition. Children that are heterozygous or homozygous dominant, will not develop galactosemia.

Answer:

its heterozygous and homozygous dominant
