Approximately what percent of the oxygen on Earth is produced through
photosynthesis?

Answers

Answer 1

Answer:

50-85%

Explanation:

Answer 2
Like all plants, they photosynthesize – that is, they use sunlight and carbon dioxide to make food. A byproduct of photosynthesis is oxygen. Scientists believe that phytoplankton contribute between 50 to 85 percent of the oxygen in Earth's atmosphere.

Related Questions

Plants take up carbon dioxide (CO2) during photosynthesis and release it during respiration. According to the article, how might increasing global temperatures affect the amount of carbon dioxide plants release during respiration?

Answers

Increasing global temperatures are likely to increase the amount of carbon dioxide that plants release during respiration. This is because higher temperatures can increase the rate of respiration, causing plants to consume more oxygen and release more carbon dioxide.

Additionally, higher temperatures can also have a negative impact on plant growth and development, which can further increase the amount of carbon dioxide released during respiration. For example, if plants are exposed to prolonged periods of high temperatures, they may become stressed and allocate more resources to respiration instead of growth, which can result in increased carbon dioxide emissions.

Overall, increasing global temperatures are likely to have complex and potentially negative impacts on plant growth, respiration, and carbon dioxide emissions.

If you found a white sheep and wanted to determine its genotype, with what kind of animal would you cross it

Answers

The ideal would be to cross this sheep with several black sheep and observe the color of each offspring.

We can arrive at this answer because:

When crossing white sheep with black sheep it is possible to observe the genotypes of the offspring to determine the genotype of the white sheep.This will be even more efficient if we know the genotype of the black sheep.In this case, if the crossing of the white sheep with the black sheep generates an offspring with all individuals with black fur, we can determine that the white sheep has the h0m0zygous recessive genotype.If the offspring is composed entirely of individuals with white fur, we can state that the white sheep has the dominant h0m0zygous genotype.If the offspring have most of their members with white fur and a small amount with black fur, it means that the white sheep has a heterozygous genotype.

In this case, the observation of the offspring's fur is essential to determine the genotype of the white sheep.

A. Adenine
B. Guanine
C. Uracil
D. Thymine

Answers

Cytosine, a nitrogenous base found in DNA and RNA, pairs with guanine. The correct answer is option B.

This pairing is based on the complementary base pairing rule in which cytosine forms three hydrogen bonds with guanine. The other base pairs in DNA are adenine with thymine, and in RNA, adenine pairs with uracil. The complementary base pairing is crucial for DNA replication and transcription processes. Cytosine and guanine, along with adenine and thymine/uracil, form the base pairs that make up the rungs of the DNA double helix structure.Understanding base pairing is fundamental to understanding the structure and function of nucleic acids.

Answers

DNA and RNA have similarities in their nucleotide composition and involvement in genetic processes. However, they differ in their sugar type, strandedness, and specific functions in protein synthesis. Understanding these similarities and differences is crucial for comprehending the fundamental mechanisms of genetics and cellular processes.

RNA and DNA are both nucleic acids that play essential roles in genetic information and protein synthesis. However, they differ in various aspects.

DNA, or deoxyribonucleic acid, is a double-stranded molecule composed of nucleotides. It contains the sugar deoxyribose and the nitrogenous bases adenine (A), cytosine (C), guanine (G), and thymine (T). DNA carries the genetic code and serves as the hereditary material in most organisms.

On the other hand, RNA, or ribonucleic acid, is typically single-stranded and contains the sugar ribose. RNA also consists of nucleotides, but it uses uracil (U) instead of thymine as a nitrogenous base. RNA has several forms, including messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). Each form has specific roles in protein synthesis.

In terms of function, DNA stores and transmits genetic information, while RNA helps translate that information into proteins. DNA is primarily located in the nucleus of cells, while RNA is found in both the nucleus and cytoplasm.

What is the primary reason organisms
undergo cellular respiration?
to get rid of wastes
to convert food to useable energy
to supply plants with carbon dioxide
+
to create energy from the sun

Answers

The primary reason organisms undergo cellular respiration is to convert food to usable energy.

Cellular respiration is a metabolic process that occurs in the cells of living organisms and involves the breakdown of organic molecules, such as glucose, to release energy in the form of ATP. This process is essential for cells to carry out their normal functions and for organisms to maintain their life processes.

Cellular respiration involves a series of reactions that break down glucose into smaller molecules, which are then used to generate ATP. During this process, oxygen is consumed and carbon dioxide is produced as a waste product. The process of cellular respiration is an efficient way for cells to convert the energy stored in food molecules into usable energy, which is essential for cell growth, repair, and reproduction.

In contrast, photosynthesis is the process by which plants and some bacteria use energy from sunlight to convert carbon dioxide and water into glucose and oxygen. This process is essential for plants to produce their own food and to release oxygen into the atmosphere.

Motion energy refers to the energy related to an object's movement. When an object is in motion, it possesses kinetic energy, which is a form of motion energy.

How to explain the energy

The matching will be:

motion energy = energy related to an object's movement

chemical energy = stored energy related to positions of atoms within molecules

thermal energy = energy of motion of particles in a substance

nuclear energy = energy released when a nucleus splits or combines

gravitational potential energy = energy related to height

sound energy = energy generated by vibration of a string

Chemical energy is stored energy that is related to the positions of atoms within molecules. It is the energy that can be released or absorbed during a chemical reaction. When chemical bonds are formed or broken, energy is either released (exothermic reaction) or absorbed (endothermic reaction) in the process.

Visual perception is the capacity to make sense of the world by employing light in the visible spectrum reflected by objects in the environment, including photopic vision (daytime vision), colour vision, scotopic vision (night vision), and mesopic vision (twilight vision). This is distinct from visual acuity, which is the measure of how sharply one can see (for instance, "20/20 vision"). Even if they have 20/20 vision, a person can still experience difficulties processing visual information.

The ability to receive sounds through an organ, such as the ear, by detecting vibrations as periodic changes in the pressure of an environment is known as hearing or auditory perception.
