Which of the following statements describes a process that occurs during photosynthesis but not during cellular respiration?
ATP is produced that stores energy.
O
Chemical energy is converted to light energy.
Reactions occur in the mitochondria of the cell.
Light energy is converted to chemical energy.

Answers

Answer:

D (see below for explanation)

Explanation:

Using the process of elimination, we can go down the answer choices:

A) ATP is produced that stores energy.

In photosynthesis, light energy, water, and carbon dioxide is taken in and converted to oxygen and glucose. Cellular respiration, however, uses glucose and oxygen and converts it to water, carbon dioxide, and ATP.

As you can see, there is no mention of ATP in photosynthesis. ATP is not created in photosynthesis—photosynthesis' main purpose is to make food for the organism.

So A is not the answer.

B) Chemical energy is converted to light energy.

In photosynthesis, the light energy taken in is converted to chemical energy so it can be used. Cellular respiration requires only oxygen and glucose, so light energy doesn't relate to cellular respiration directly.

However, if you read the answer carefully, it says that chemical energy is converted to light energy. The main purpose is to use the light energy, which cannot be used in its light form, so it has be converted into chemical energy.

So B is not the answer.

C) Reactions occur in the mitochondria of the cell.

Photosynthesis occurs in the chloroplasts of an organisms. Heterotrophs do not have chloroplasts, so they cannot make their own food. However, mitochondria are in all eukaryotic cells, as cellular respiration occurs in all eukaryotic cells as well.

Cellular respiration happens in the mitochondria of a cell. Photosynthesis does not.

So C is not the answer.

D) Light energy is converted to chemical energy.

If you go back to my explanation for B, you can see that photosynthesis uses light energy, but to do so, it has to convert it to light energy first. It cannot use light energy itself.

So D is the right answer.

How does inorganic nitrogen from the atmosphere
(N2) get into living systems?

Answers

Answer:

When an organism excretes or dies, nitrogen is in the form of organic nitrogen in its tissues (e.g. amino acids, DNA). During the ammonification process, many fungi and prokaryotes then break the tissue down and release inorganic Nitrogen into the atmosphere as ammonia.

Explanation:

Plants use their roots for nitrogen compounds. When they consume the seeds, animals acquire certain chemicals. When plants and livestock die, or animals excrete waste, the organic nitrogen compounds return to the soil, where microorganisms known as decomposers break down their compounds.

Answers

The answer is b.mitosis

Meiosis has evolved to produce the greatest variation of offspring.

What is meiosis?

Meiosis is a type of cell division that occurs in eukaryotic cells, such as those in animals and plants, to produce reproductive cells (gametes) that have half the number of chromosomes as the parent cell.

During meiosis, chromosomes pair up and  genetic material through a process called crossing over, creating genetic diversity among the gametes. This diversity increases the chances that at least one offspring will be better suited to its environment and increase the survival chances of the species.

Sometimes new ideas in science come from traditional methods people used in the past. What did researchers learn from terra preta? How is bio-char different from the traditional Amazonian method of creating terra preta?

Answers

Answer:

What did researchers learn from terra preta?...  Because terra preta is loaded with so-called bio-char -- similar to charcoal -- it also can pull substantial amounts of carbon out of the increasing levels of carbon dioxide in the Earth's atmosphere, helping to prevent global warming.

How is bio-char different from the traditional Amazonian method of creating terra preta?  Terra preta owes its characteristic black color to its weathered charcoal content, and was made by adding a mixture of charcoal, bone, broken pottery, compost and manure to the low fertility Amazonian soil. ... Terra preta soils were created by farming communities between 450 BCE and 950 CE..  

The BBC's Unnatural Histories presented evidence that the Amazon rainforest, rather than being a pristine wilderness, has been shaped by man for at least 11,000 years through practices such as forest gardening and terra preta.

Terra preta is a type of dark, fertile soil found in the Amazon rainforest that is believed to have been created by indigenous people thousands of years ago. Researchers have learned from terra preta that it contains a high level of carbon, along with nutrients such as nitrogen, phosphorus, and potassium.

What is terra preta soil?

Terra preta, or "black earth," is a type of dark, fertile soil found in the Amazon rainforest that is believed to have been created by indigenous people thousands of years ago. Scientists have studied terra preta to understand its unique properties and how it was created. Terra preta is a type of anthropogenic soil, which means that it was created by human activity rather than natural processes. It is believed that the indigenous people of the Amazon region created terra preta by adding biochar to soil along with other organic materials such as bones, shells, and manure.

Hence, researchers have learned from terra preta that it contains a high level of carbon along with nutrients such as nitrogen, phosphorus, and potassium.

Protein synthesis is the generation of proteins by cells that employ DNA, RNA, and different enzymes.

What is protein synthesis?

It generally includes transcription, translation, and post-translational events, such as protein folding, modifications, and proteolysis the process of protein synthesis.

the mRNA contains the sequence of nucleotides transcribed from the DNA that defines the sequence of amino acids that a synthesized protein will have.

In mRNA, codons are triplets of nitrogenous nucleotides that code for amino acids and using ribosomes mark the beginning and end of protein synthesis.

Therefore, in contrast to mRNA codons, anticodons are triplets of nucleotides found in transfer RNA (tRNA). The linking of amino acids to the polypeptide chain being produced is carried out by tRNA.
