explain how redox reactions are involved in energy exchanges

Answers

Answer 1

Answer:

In redox reactions, energy is released when an electron loses potential energy as a result of the transfer. Electrons have more potential energy when they are associated with less electronegative atoms (such as C or H), and less potential energy when they are associated with a more electronegative atom (such as O).

Which of these graphs represents the effect of temperature on the rate of photosynthesis? Explain your answer.

WILL MARK BRAINLIEST!!

Answers

a. A describes the effect of light intensity on photosynthesis.

Answer: A

Explanation:
In plants and other primary producers, photosynthesis is a biological mechanism that is vital to energy production. Energy-containing carbohydrates are derived from light, water and carbon dioxide in the form of glucose molecules.
The waste product oxygen is released as a result. Photosynthesis depends on many variables, including:
carbon dioxide concentration,
ambient temperature
and light intensity
It is a rate-limited reaction. Since photons or particles of light provide the energy required for the reaction, high intensities of light increase the photosynthetic rate. From the graph shown, as the intensity increases steadily, so does the rate- but at too high of an intensity, it ceases to affect the rate of photosynthesis, which becomes constant or plateaus.
Beyond this point, either the supply of carbon dioxide or the temperature limits the reaction. For instance, at high intensities tissues may even be damaged by high temperatures or heat.

Graph A represents the effect of temperature on the rate of photosynthesis.

Why is photosynthesis affected by temperature?

Photosynthesis is a biological process that is essential to the synthesis of energy in plants and other primary producers. Light, water, and carbon dioxide combine to generate glucose molecules, which are the building blocks of energy-containing carbohydrates.

As a result, the waste product oxygen is emitted. Numerous factors affect photosynthesis, such as the amount of carbon dioxide present, the surrounding temperature, and the amount of light. It is a reaction with a rate constraint. High light intensities accelerate the rate of photosynthetic reaction because photons, or light particles, supply the energy needed for the reaction. According to the graph, the rate rises steadily as the intensity does, but at a certain point, the intensity stops having an impact and the rate of photosynthesis plateaus or becomes constant.

Beyond this point, the reaction is restricted by either the temperature or the carbon dioxide supply. For instance, at high intensities, heat or high temperatures may even harm tissues.

Which group was not present in Linnaeus' system but is present in modern classification systems? A) Species B) Kingdom C) Domain D) Phylum HELP ME

Answers

Answer:

D) Phylum

Explanation:

The group that was not present in the Linnaeus' system but is present in modern classification systems is Domain. The correct option is C.

What is Linnaeus classification system?

The Linnaean classification system is based on a hierarchy of groupings known as taxa. Taxa vary from kingdoms to species.

The kingdom is the most extensive and inclusive grouping. It is made up of organisms that have only a few basic resemblances.

The Linnaean system is significant because it paved the way for the use of binomial nomenclature to distinguish between species.

Scientists could communicate instead of using misleading common names once the system was implemented.

Domain is a group that was not present in Linnaeus' system but is present in modern classification systems.

Thus, the correct option is C.

Explanation:

New cells are created from existing cells through a process referred to as the cell cycle

in all organisms, certain genes are expressed at any given time while other genes are not. both prokaryotes and eukaryotes regulate gene expression at the transcription stage. however, the greater complexity of eukaryotic cells makes it possible for gene expression to be regulated at many other stages as well. the diagram below shows different stages at which gene expression may be regulated in eukaryotes.

Mitosis maintains chromosomes in each {blank} while meiosis maintains chromosome number in the {blank}.

Answers

Answer:

Mitosis maintains chromosomes in each cell division constant, while meiosis maintains chromosome number in half

Explanation:

Mitosis maintains chromosomes in each daughter cell while meiosis maintains chromosome number in the gametes.

What is mitosis and meiosis?

Mitosis is the process by which a cell divides into two identical daughter cells, each with the same number and type of chromosomes as the parent cell. During mitosis, the cell's DNA is replicated, and the replicated chromosomes are evenly distributed into the two daughter cells. This ensures that each daughter cell receives a complete set of chromosomes, maintaining chromosome number in the daughter cells.

Meiosis, on the other hand, is the process by which a cell divides into four non-identical daughter cells, known as gametes. During meiosis, the cell's DNA is replicated, and the replicated chromosomes are shuffled through a process called crossing over. This shuffling results in gametes with unique combinations of chromosomes, which helps to maintain chromosome number in the gametes. Gametes, also known as sex cells, are the cells involved in sexual reproduction, and they are important for maintaining chromosome number in offspring.

The concept is creating a genetically modified organism, or GMO. This specifically would be done to try to water plants salt water and they could still grow. This is a pro in an area with little to no freshwater available, such as extreme drought. The cons of this is it would kill any other non salt water tolerant plant. Salt building up in the soil would make it so no other plant could grow there in the future, unless it was also made into a gmo. Overall this is not a feasible solution for most areas and most crops.
