Which processes produce the carbon dioxide from the original glucose molecule? Which processes do NOT produce CO2 molecules? (this is abt cell respiration)

Answers

Glycolysis in cellular respiration and during the process glucose is oxidised to carbon dioxide and water. Processes that produce: glycolysis,link reaction,the Krebs cycle and the electron transport chain

The process that is responsible for the production of carbon dioxide from the original glucose molecule is known as Cellular respiration.

What is Cellular respiration?

Cellular respiration may be defined as a biological process through which a form of sugar which is known as Glucose is transferred into energy in the form of ATP in the presence of oxygen. This energy is required to accomplish metabolic activities.

The complete reaction of cellular respiration is as follows:

Glucose + Oxygen → Carbon dioxide + Water + Energy (ATP).

The process that does not produce carbon dioxide molecules is the oxidation of food during respiration. In other words, it is known as Lactate fermentation. Lactate fermentation initiates with glycolysis and forms lactate.

Therefore, the process that produces carbon dioxide and the process that does not produce carbon dioxide is well described above.

How does energy and matter move through the ecosystem

Answers

Answer:

Using the food chain which originates from the sun's energy.

Explanation:

Answer:

matter moves through an ecosystem through the recycling of energy and nutrients between different trophic levels. The first trophic level consists of primary producers like plants that can be manufactured their own food through photosynthesis. Similarly plants are require nutrients like nitrogen to grow.

Explanation:

Fossils of canines were found on opposite sides of a mountain range. The fossils are from species that are anatomically similar, but the climates were extremely different on each side of the range. Which type of evidence for evolution do these fossils exemplify?
A. vestigial structures
B. analogous structures
C. coevolution
D. biogeography

Answers

The phenomenon described in the question is an example of coevolution.

What is coevolution?

Evolution refers to the changes that occur in organisms as they metamorphose from one form to another over a given time interval. The changes that occur in one specie usually affects the changes that occur in related species. This is known as coevolution.

Hence, if fossils of canines were found on opposite sides of a mountain range and they belong to species that are anatomically similar, but the climates were extremely different on each side of the range, it is an example of coevolution.

D.A series of severe weather events in the habitat.

Answers

Answer:

a series of severe weather events in the habitat

An increase in the population of an organism would most likely be associated with a series of severe weather events in the habitat. The correct option is D.

What is the population?

A collection of creatures from the same species that can interact to create fertile progeny. It is on a level above organisms but below the ecosystem and community.

An ecosystem is a level of organization where several communities of various species and the associated abiotic elements interact. It is the place where different population interacts with each other.

A biosphere and a biome are larger organizational levels than this one. Communities are levels of the organization where various populations coexist and engage in social interactions.

Therefore, the correct option is D. A series of severe weather events in the habitat.

Answer:

B. Energy is transferred from the cooler air to the warmer ground.

Explanation:

When cooler air particles come into contact with the warmer ground, energy is transferred from the cooler

air to the warmer ground.

Answer: The temperature of air would decrease.

Explanation:

The energy gets transferred from hot object to cold object until the two objects are in thermal equilibrium. When air transfers energy to a cooler object, it means the air it self is cooling down till the air and the object are in thermal equilibrium. Thus, the temperature of air would decrease.

Explanation:

SDS-PAGE (sodium dodecyl sulphate–polyacrylamide gel electrophoresis), is an electrophoretic methodology used to separate proteins that have a molecular weight between 5 to 250 kDa. SDS is a well-known ionic detergent that is able to break hydrophobic interactions and hydrogen bonds. Moreover, size-exclusion chromatography is a filtration technique that separates molecules in solution according to their molecular size. In this case, SDS-PAGE showed that the target protein is composed of two identical subunits (monomers) of 80 kDa each, which were separated by the detergent and formed one single band in the SDS-PAGE gel.

The central dogma describes which of the following?


the process by which enzymes are modified after translation


the way DNA is replicated


the flow of genetic information


the way RNA is used as a template to make DNA

Answers

Answer:

The correct answer is - the flow of genetic information.

Explanation:

The process includes the flow of genetic information or instructions encoded in DNA used to make or turn to a final product that can be DNA or protein, known as the central dogma.

Mostly central dogma term use for the protein synthesis from the DNA that takes place in the two steps, transcription is the first converts DNA into RNA and the second translation that converts product of the first step that is RNA  into Protein. DNA → RNA → protein.

Thus, the correct answer is - the flow of genetic information.

The central dogma describes the flow of genetic information. The correct option is C.

A key idea in molecular biology known as the core dogma outlines how genetic information moves through cells. It says that RNA is translated into proteins from transcribed DNA.

This idea emphasises how genes are expressed and proteins are made in living things by sequentially transferring genetic information from DNA through RNA to proteins.

The fundamental dogma excludes DNA replication, the reverse transcription of RNA into DNA, and the process of post-translational enzyme modification.

Thus, the correct option is C.

prophase I
metaphase I
anaphase I
telophase I

Answers

Answer:

The correct answer is - prophase I

Explanation:

Crossing over or recombination is the event that takes place during the pachytene stage of Prophase I of Meiosis I. During this event, the exchange in genetic material between non-sister chromatids of homologous chromosomes results in the recombination of the genetic material or recombinant chromosome.

Prophase I is the first stage which is characterized by the condensation of the chromosome and form tetrad and appeared to be X like structure in the cell and followed by the crossing over or genetic exchange of homologous chromosomes.

Refer to the illustration above. Which of the cells will be a diploid cell at the completion
of division?

Answers

Yes it is easy my guy it’s b just wait til u get to chemistry

Both the cells will be diploid cells at the completion of division. Therefore, the correct option is B.

In diagram 1, the chromosomes are in the metaphase of cell division, that is aligned at the centre of the cell. In the next phase which is anaphase, these chromosomes are pulled apart by the spindle fibres in opposite directions. As a result, the chromosomes are split into half and each cell gets half the number of chromosomes in the form of chromatids. Thus, each cell will have 4 chromatids.

In diagram 2, the chromosomes are in the early anaphase stage. When the cell will split into two, each daughter cell will have 2 chromosomes. These chromosomes separate in the telophase and thus, each cell will have 4 chromatids.

The bacteria that make yogurt carry out lactic acid fermentation, as do the red blood cells in your body, which don't have mitochondria and thus can't perform cellular respiration.

A museum curator collects fossils from two different periods. He has 400 from one period and 204 from a later period. He plans to arrange the fossils in display cases so that each case contains the same number of fossils. Also, each case must contain fossils from only one period. What is the largest number of fossils that can be placed in each case

Answers

Answer:

4

Explanation:

Number of fossils collected over period 1:

400

Number of fossils collected at a later period :

204

For each display case to have the same number of fossils ; the greatest number of fossils possible per case:

Obtain the greatest common factor of both 400 and 204

400 = 1, 2, 4, 5, 8, 10, 25, 40, 50, 80, 100, 200, 400

204 = 1, 2, 3, 4, 6, 12, 17, 34, 51, 102

Hence, the greatest common factor (400 and 204) is 4

Hence, the greatest Number of Fossil possible per case = 4
