What's the difference between primary succession and secondary succession

Answers

Answer 1
Primary succession occurs on newly exposed surfaces- it is an ecological change that begins in an area where no remnants of an older community

Secondary succession occurs in a disturbed area where remnants or previous ecosystems (coil and even plants) remain
Answer 2

Final answer:

The difference between primary and secondary succession is that primary succession occurs on newly formed land with no soil, requiring pioneer species to create soil, while secondary succession occurs on disturbed land with existing soil, allowing for faster recovery.

Explanation:

Ecological succession is the process where a community experiences a sequence of changes with the appearance and disappearance of species over time. The main difference between primary succession and secondary succession lies in the condition of the environment where the succession begins.

Primary succession occurs in areas where no soil exists because it's a newly formed or exposed environment, such as land formed from lava flow or locations where glaciers have retreated. Here, the environment is colonized by pioneer species which can grow in such harsh conditions and gradually create soil by breaking down rock and contributing organic matter as they die off.

In contrast, secondary succession happens in areas that were once home to existing life but were disturbed by events like wildfires or human activities. In these cases, soil is already present, and remnants of the destroyed community provide a basis for new growth. Succession in these situations tends to be faster than primary succession because the soil already contains nutrients needed for plant growth.

Which of these is an example of chemical change breaking glass melting ice on windshield burning gasoline denying a bumper

Answers

Answer: Option (c) is the correct answer.

Explanation:

It is known that chemical changes are the changes which tend to show difference in chemical composition of a substance.

For example, toxicity, reactivity, combustion etc are all chemical properties.

When gasoline is burning then a chemical change takes place as combustion is taking place.

A chemical change will always lead to the formation of a new compound and this change is irreversible in nature by any physical means.

On the other hand, a change which is unable to bring any difference in chemical composition of a substance is known as a physical change.

For example, change in shape, size, mass, volume etc are all physical properties.

Breaking glass, melting ice on windshield and denying a bumper are all physical changes.

Thus, we can conclude that out of the given options burning gasoline is an example of chemical change.

Answers

Cohesion holds hydrogen bonds together to create surface tension on water, in other words Cohesion is water that is attracted to water
Adhesive forces pull the water closer to other molecules, which is basically water that is attracted to other substances

Final answer:

Cohesion refers to the attractive force between molecules of the same substance, while adhesion is the interaction between molecules of different substances. Examples include water droplets exhibiting surface tension for cohesion and water adhering to wax paper or moving up a thin tube through capillary action for adhesion.

Explanation:

Cohesion and Adhesion Explained

Cohesion is the force that holds molecules of the same substance together. This property is exemplified by droplets of water forming on a surface, such as wax paper; the water molecules remain together, exhibiting the cohesive force. A notable phenomenon related to cohesion is surface tension, which allows certain insects to walk on water without sinking.

Adhesion is the interaction that occurs between molecules of different substances, leading them to stick together. An example of adhesion is when water droplets adhere to a sheet of wax paper, even when turned upside down, showing the attraction between the water molecules and the paper's surface. The effect of adhesion is clearly seen in capillary action, where water can move up thin tubes or through porous materials, opposing gravity.

Which valuable mineral is often found in the rock called kimberlite?
A.goldB.silverC.diamondD.platinum

Answers

The answer to your question is C. Diamonds

Answer:

The correct answer is option C.diamond.

Explanation:

Kimberlite is a type of heavy and fragmented igneous rock that contains the highly valued diamond mineral. Remember that igneous rocks are formed with hot magma that comes from the interior of the Earth and as it ascends to the surface it cools and creates these types of rocks that contain minerals.

Although diamond is one of the minerals that compose it, it is not the most abundant. The most abundant mineral is olivine, and among other of its minerals is also phygopitta mica.

This rock formation can be found in areas with elevated centers of continental platforms.

what makes a molecule a saturated fat?

Answers

A molecule is considered to be a saturated fat when there is a single bond present.

Final answer:

A molecule is a saturated fat when it consists of carbon chains having only single bonds between carbons, making it fully 'saturated' with hydrogen atoms. These fats have straight chains, can pack tightly together, and are solids at room temperature.

Explanation:

A molecule is classified as a saturated fat when it is a type of simple lipid molecule with a carbon chain bonded to the maximum number of hydrogen atoms possible. This means that each carbon atom in the chain is linked to adjacent carbons by single bonds only, without any carbon-to-carbon double bonds (C=C). Saturated fatty acids comprise these simple lipid molecules and contribute to the molecule's straight chain structure, which allows them to pack closely together. Consequently, saturated fats tend to have high melting points and are typically solids at room temperature.

What role do glucose and oxygen play in cellular respiration?

Answers

Final answer:

In cellular respiration, glucose is used as the primary fuel to produce ATP, while oxygen acts as an essential electron acceptor for efficient ATP production. Without oxygen, much less ATP is produced, demonstrating the necessity of both glucose and oxygen in energy metabolism within cells.

Explanation:Role of Glucose and Oxygen in Cellular Respiration

During the process of cellular respiration, glucose and oxygen play critical roles. Glucose serves as the primary fuel, with its breakdown releasing the energy necessary for the synthesis of adenosine triphosphate (ATP). Oxygen, meanwhile, is crucial for accepting electrons at the end of the electron transport chain, allowing for the efficient production of ATP. Without oxygen, only a limited amount of ATP can be produced through anaerobic pathways.

The Reactants and Products of Cellular Respiration

Glucose enters the body from food intake and is transported by the cardiovascular system from the digestive system to the cells. Oxygen is inhaled into the lungs, diffuses into the bloodstream, and is also carried to the cells. In the presence of oxygen, cellular respiration begins with glycolysis, releasing just two molecules of ATP, and culminates in the mitochondria through the citric acid cycle and the electron transport chain. This leads to the production of the majority of ATP, with carbon dioxide and water as waste products.

Comprehensive Cellular Respiration

Most steps of cellular respiration, including the final and most ATP-productive ones, occur within the mitochondria of cells. All organisms that require oxygen perform cellular respiration to convert glucose into the usable energy of ATP. The overall transformation during cellular respiration involves the consumption of glucose and oxygen and the release of carbon dioxide, water, and ATP. As a result, cellular respiration is essential for powering various cellular processes across organ systems, notably involving the digestive, cardiovascular, and respiratory systems.

Final answer:

In cellular respiration, glucose is broken down with the help of oxygen to produce ATP, carbon dioxide, and water. Oxygen's crucial role is to serve as the final electron acceptor in the electron transport chain, allowing for efficient ATP production. Without oxygen, the ATP yield would be greatly reduced.

Explanation:

Glucose and oxygen play crucial roles in the process known as cellular respiration, which is the method by which cells convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. Oxygen acts as the final electron acceptor in the electron transport chain, which is necessary for the production of ATP. Without oxygen, the electron transport chain would not function, significantly reducing the amount of ATP produced by cellular respiration.

In the presence of oxygen, glucose undergoes a series of reactions that result in the production of carbon dioxide and water as waste products, and the most importantly, ATP, which is the main energy currency of the cell. Each molecule of glucose, through the process of cellular respiration, can produce a significant number of ATP molecules, which the cell uses for various energy-requiring functions.

Cellular respiration is a multi-step process starting with glycolysis, continuing through the citric acid cycle, and concluding with oxidative phosphorylation at the electron transport chain. This intricate process involves the digestive, cardiovascular, and respiratory systems, as glucose comes from the food we eat, and the oxygen needed for respiration is obtained from the air we breathe.

A because to get a scientific theory you have to prove it by multiple trials of the exact same thing. it can be proven thrugh work

The statement C. "eventually becomes a fact" does not describe a scientific theory. Scientific theories remain theories despite extensive evidence and are open to revision; they don't become 'facts'.

The statement that does not accurately describe a scientific theory is "eventually becomes a fact." It's important to note that a scientific theory is a well-substantiated explanation of aspects of the natural world that has been consistently supported by a large body of evidence and facts obtained from multiple observations and experiments. A scientific theory is generally accepted among scientists due to its robust support, not because it has morphed into a fact over time.

Additionally, scientific theories are designed to be testable and are subjected to rigorous testing and refinement. While a theory may be widely accepted and highly reliable due to extensive evidence, it remains open to scrutiny and revision should new evidence emerge.

A sample of an unknown liquid has a volume of 30.0 mL and a mass of 6 g. What is its density? Show your work or explain how you determined this value.

Answers

Alright, so the formula for density is d=m/v or in words, density is equal to the mass divided by the volume. Since grams (g) is a unit of mass, you will place that at the top of your fraction, and since mL is a unit of volume, it will be placed at the bottom. Your equation will look like D=6/30.0 mL When you answer the question, your unit will be g/mL. Hope this helps!

Answer:

Density of liquid having a volume of 30.0 mL and a mass of 6 g is

[tex]0.2 \frac{g}{ml}[/tex]

Explanation:

Density of a substance is given by mass divided by volume

Mathematically it can be represented as

[tex]D = \frac{M}{V}[/tex]

Where D represents the density

M represents the mass and

V represents the volume

Substituting the given values in above equation we get -

[tex]D = \frac{6}{30} \\= 0.2\frac{g}{ml} \\= 200 \frac{Kg}{m^3}[/tex]

Hence, density of liquid having a volume of 30.0 mL and a mass of 6 g is

[tex]0.2 \frac{g}{ml}[/tex]
