What happens when you combine two clear liquid solutions, a thick black solid material forms on the bottom of the beaker.

Answers

Answer 1

Answer:

See explanation

Explanation:

A precipitate is formed when a mixture of two soluble substances results in the formation of an insoluble product. It usually happens during a double decomposition reaction.

The two clear liquids combined both contain soluble substances. These interact to yield an insoluble product also known as a precipitate which is black in colour and settles on the bottom of the beaker.

In the carbon cycle, several processes contribute to the movement of carbon through the ecosystem. For each of the types of movement below, name the process in the carbon cycle that accomplishes it: A. Movement of carbon from the atmosphere into living organisms: ___________________ B. Movement of carbon from living organisms into the atmosphere: ___________________ C. Movement of carbon between different organisms due to feeding: ____________________

Answers

Answer:

A. Movement of carbon from the atmosphere into living organisms: PHOTOSYNTHESIS

B. Movement of carbon from living organisms into the atmosphere: RESPIRATION.

C. Movement of carbon between different organisms due to feeding: DECOMPOSITION

Explanation:

Carbon is the main element in the compounds that make up living organisms. It is found in the remains of living organisms, fossil fuels, inorganic salts, water bodies and air. It is continuously being removed from and added to the carbondioxide in the atmosphere.

The CARBON CYCLE is defined as the process which brings about the circulation of carbon compounds in nature. These processes include:

--> PHOTOSYNTHESIS: Green plants (producers) are continuously removing carbon dioxide from the atmosphere for photosynthesis. The carbon of the carbon dioxide is incorporated into sugars and other complex organic compounds in plants' tissues. When the plants are eaten by animals (primary consumers), the plant material is digested, absorbed and built up into compounds which form animal tissues. Thus, this accomplishes movement of carbon between different organisms due to feeding.

--> RESPIRATION: Plants and animals respire all the time to obtain energy. During this process, sugar are broken down to liberate carbondioxide and water as wastes. Thus this accomplishes the movement of carbon from living organisms back into the atmosphere.

--> DECOMPOSITION: This is a process in carbon cycle where decomposers feed on the dead and decaying organisms and their excreta and bring about their decomposition. They have enzymes that break down organic compounds into simple inorganic compounds. Although inorganic compounds (carbondioxide) are released during decay, decomposers absorb these compounds for their own use. When decomposers doe, othe decomposers feed on them thereby accomplishing the movement of carbon between different organisms due to feeding.

In the early 1900s, three species of goatsbeard wildflowers, T. dubius, T pratensis, and T. porrifolius, were introduced to the United States. Each of the species had a chromosome number of 2N. In the 1930’s, a few populations of offspring from the original wildflowers were identified as having a chromosome number 4N. What does this data suggest about speciation.
A. Speciation has occurred because the original species of wildflowers produced populations of viable offspring.
B. Speciation has occurred because breeding between the offspring and original populations would not be possible.
C. Speciation has not occurred because the offspring of the original wildflowers were not introduced into a new area.
D. Speciation has not occurred because the offspring inherited identical genetic information to the original wildflowers.

Answers

Answer:

B. Speciation has occurred because breeding between the offspring and original populations would not be possible.

Explanation:

Speciation has occurred in the species due to no breeding between the offspring and original populations because the offspring and original species has different number of chromosomes in their DNA. Due to this difference in the chromosome number in the DNA, there is no chance of breeding between offspring and original species. Speciation is the evolutionary process by which populations of organism evolve with the passage of time and become different from the original species.

Which of the following is correct about mutations and genetic variation?

It must be present in a population before natural selection can act upon the population.
It arises in response to changes in the environment.
It tends to be reduced when diploid organisms produce gametes and reproduce.
It is created by the direct action of natural selection.

Answers

Answer:

a. It must be present in a population before natural selection can act upon the population.

Explanation:

Genetic variation is the difference in the DNA sequences in individuals, which makes a member of a species different from another member of the same species. It can also be said to be the differences in the genetic make up of individuals of a species population.

Genetic variation must be present in a species population before evolutionary mechanisms, such as evolution, can occur. Genetic variation must be present in a population of a species before natural selection can act upon the population, as natural selection can only increase or reduce the frequency of alleles present in the species population already.

Genetic variation in a population of species is important for natural selection to occur.

The true statement is that; "genetic mutation must exist before natural selection can act on it."

What is natural selection?

The term natural selection refers to the fact that traits that are more favorable to enable an organism to survive and reproduce tend to persist in the population.

These traits usually occur due to genetic mutations. In a population, genetic mutation must exist before natural selection can act on it.

Which statement best distinguishes aerobic from anaerobic respiration?
A. Only aerobic respiration involves fermentation.
B. Only anaerobic respiration occurs in the mitochondria.
C. Only aerobic respiration requires oxygen.
D. Only anaerobic respiration produces carbon dioxide.

Answers

Answer:

C. Aerobic respiration

Explanation:

Aerobic respiration occurs when oxygen is present

Anaerobic respiration occurs in the absence of oxygen. Anaerobic respiration is usually associated with fermentation process (eg Alchohol production)

The main difference between aerobic and anaerobic respiration is that aerobic respiration needs oxygen to occur, while anaerobic respiration does not. Option C. Only aerobic respiration requires oxygen.

What is cellular respiration?

Aerobic and anaerobic respiration occurrence depends on the presence or absence of oxygen. Option C. Only aerobic respiration requires oxygen.

Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.

What is Aerobic Respiration?

This type of respiration occurs in the presence of free oxygen. It involves a series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.

Aerobic Respiration occurs in mitochondria, and takes place in two steps or stages: Krebs cycle and electron transporter chain.

Glycolysis and Krebs cycle produce electrons. These electrons then travel along the electron transporter chain while releasing energy, and ATP is produced.

What is Anaerobic Respiration?

This is the type of respiration that occurs in the absence of free oxygen.

It is also a series of reactions by which the cell produces 2 ATP molecules by using pyruvate (product of glycolysis).

Anaerobic respiration can occur in two ways: lactic fermentation and alcoholic fermentation.

Lactic fermentation produces lactic acid and 2 ATPAlcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂

The whole anaerobic process occurs outside the mitochondria.

Options:

A). Only aerobic respiration involves fermentation. FALSE.

Anaerobic respiration involves fermentation.

B). Only anaerobic respiration occurs in the mitochondria. FALSE.

Aerobic respiration occcurs in mitochondria and anaerobic respiration occurs in the cytoplasm.

C). Only aerobic respiration requires oxygen. TRUE

Anaerobic respiration does not need oxygen.

D). Only anaerobic respiration produces carbon dioxide. FALSE

Alcoholic fermentation produces CO₂ too.

The correct option is C. Only aerobic respiration requires oxygen.

Which of these statements is true of ecosystems? a animals do not travel from one ecosystem to another ecosystem b the total amount of energy in an ecosystem does not change c air cannot be used by organisms once the air moves out of the ecosystems d matter lost by one ecosystem is gained by the surrounding environment

Answers

Answer:

I think the answer is B. I think energy decreases as it moves up tropic levels when it is lost as the organisms from one level consume the organisms in the other.

Explanation:

It can't be A because animals do travel from one ecosystem to another. It's migration. It's not C because air can be used by organisms as once as the air moves out of their ecosystem because air is everywhere and the organisms need air to breathe and to live. D is definitely incorrect because matter can't be created or destroyed. Remember that an ecosystem is the organisms physical environment. I hope this answers your question.

D, matter lost by one ecosystem is gained by the surrounding environment

Explanation: Here's an explanation for why D is right and all the other ones are wrong.
D- when matter is lost from one ecosystem, it is often gained by another nearby ecosystem. For example, when leaves fall from trees in a forest, they decompose and release nutrients into the soil. These nutrients can then be taken up by plants in the same ecosystem or be transported by water runoff to other ecosystems, such as rivers or lakes. This process of matter transfer ensures the cycling of nutrients within and between ecosystems.
A- animals can and do travel from one ecosystem to another. Birds migrate between different habitats, and some animals spread seeds or pollinate flowers in multiple ecosystems. B- the total amount of energy in an ecosystem does change over time. Energy enters an ecosystem through photosynthesis, where plants convert sunlight into chemical energy. This energy is then passed on to other organisms through the food chain. However, energy is lost as heat during these transfers and eventually leaves the ecosystem, resulting in a decrease in the total amount of energy available. C- organisms rely on air for respiration, and the exchange of gases, like oxygen and carbon dioxide, occue between organisms and the air in the environment. While air moves in and out of ecosystems, organisms continuously utilize the air for their survival.

A variegated leaf with green and yellow patches is used for an experiment to prove that chlorophyll is required for photosynthesis. Before the experiment the green portions (A), and the yellow portions (B), arte observed. What will be the colour of „A‟ just before and after the starch test? Also write the equation of photosynthesis and mark, well ash molecule the by-product is obtained.

Answers

Answer: The colour of A before the starch test is GREEN while after the starch test is BLUE- BLACK. The equation for photosynthesis is

6CO2 + 6H2O → C6H12O6 + 6O2.

Explanation:

PHOTOSYNTHESIS is the process by which green plants use energy from sunlight to manufacture their own food. It is a building up process since simple inorganic compounds such as carbondioxide and water are built up into large organic compounds such as glucose and OXYGEN is given off as a by product.

Oxygen given out in photosynthesis occurs in the light stage during the process of photolysis of water. This occurs when the chlorophyll traps, absorbs and captures light energy and become energised. The energised chlorophyll supplies energy which is to split molecules of water into hydrogen ion ( H+) and hydroxyl ion ( OH-). The hydroxyl ion is reconverted to water and oxygen is given out as a by product.

To show that chlorophyll is NECESSARY for photosynthesis, a variegated leaf with green and yellow patches is used for an experiment.

The green portion is marked A and the yellow portion marked B. The leaf is tested for starch using the procedure below:

--> place leaf in boiling water for half a minute to kill it.

--> decolorize leaf by placing it in hot alcohol.

--> dip decolorize leaf in hot water to soften it.

--> place leaf on tile and add iodine solution to it.

RESULT: It would be found that only the green parts contain starch as blue+black colouration is observed while yellow area is unaffected by iodine.

D.
Some of the matter changed from solid to gas and went into the air.

Answers

Answer: It releases oxygen and heat. The answer is C

Stored inside the match head is another chemical called “potassium chlorate”. When it gets hot, it releases a lot of extra oxygen and heat. This makes the match head burn quickly and strongly. When you put it all together the heat, the fuel, and the oxygen  you get a flame. Matter does not go when something is set on fire. Matter is always the same.  Burning is a chemical process. The flames are caused as a result of a fuel undergoing combustion (burning). (CC BY-SA 2.5; Einar Helland Berger for fire and Walter Siegmund for ash).
