identify one piece of evidence that supports oxygenation to atmosphere from cyanobacteria
Answers
One piece of evidence that supports oxygenation of the atmosphere from cyanobacteria is the presence of fossilized stromatolites. Stromatolites are layered rock structures that form over time as layers of cyanobacteria and other microbes build up and trap sediment particles.
These structures date back to around 3.5 billion years ago and are considered to be some of the earliest evidence of life on Earth.
Stromatolites are composed of layers of sediment interspersed with layers of cyanobacterial biofilms. These biofilms are believed to have played a significant role in the oxygenation of the atmosphere. Cyanobacteria are photosynthetic organisms that use energy from sunlight to convert carbon dioxide and water into organic compounds, releasing oxygen as a byproduct. This process, known as oxygenic photosynthesis, is responsible for the majority of oxygen in the atmosphere.
The presence of fossilized stromatolites provides evidence that cyanobacteria were present on Earth and actively engaged in photosynthesis, releasing oxygen as a byproduct, billions of years ago. This supports the hypothesis that the oxygenation of the atmosphere was driven by the activities of photosynthetic organisms, particularly cyanobacteria.

In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) and oxygen (O2). In the process of aerobic respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. The chemical equations that describe these reactions look like this:
6CO2 + 6H2O + light C6H12O6 + 6O2 C6H12O6 + 6O2 6CO2 + 6H2O + energy
How do these equations explain why the total amount of O2 and CO2 remains the same?
Answers
Answer:
During photosynthesis, to form 1 molecule of glucose, 6 molecules of CO2 is needed to be used as a reactant. 6 molecules of O2 is released as a by-product.
However, during aerobic respiration, to hydrolyse 1 molecule of glucose, you will need 6 molecules of O2 as a reactant, releasing 6 molecules of CO2 as by-product.
Essentially, the total amount of CO2 and O2 remains the same assuming the rate of aerobic respiration is the same as the rate of photosynthesis, resulting in no net gain or loss of both CO2 and O2 in the atmosphere.

Explanation:
All living things have certain characteristics. The genetic code carries the directions for inheritance, and offspring usually resemble their parents. With asexual reproduction, offspring have the same traits as their parents. With sexual reproduction, offspring differ from their parents in some ways. Living organisms use energy and materials to grow, develop, and reproduce. These life processes involve a set of chemical reactions called metabolic reactions. Organisms have means of detecting a change in their environment and responding to this stimuli. Most organisms require that their internal environments remain in a fairly constant range, and so they maintain homeostasis. The ability of a group of organisms to change, or evolve, over time is necessary for survival in an ever-changing environment.
Sexual reproduction involves crossing over of genetic materials between non-homologous chromosomes during gamete formation unlike in asexual reproduction. Hence, offspring from sexual reproduction differ from their parents to an extent while those from asexual reproduction are clones of their parents genetically.
Life is generally sustained by chemical processes known as metabolic reactions. Substances are constantly being formed (anabolic) and being broken down (catabolic) within the body of living organisms.
Organisms respond to stimuli in their environment. They are equipped with means to detect changes and act accordingly. Most living organisms are required to maintain a relatively constant internal environment. The process of doing this is known as homeostasis. Organisms need to constantly evolve in order to keep up with ever-changing environment.

when new plants are formed by cuttings (or calluses) from older plants, why do they look just like the parent plants?
Answers
When new plants are formed by cuttings or calluses from older plants, they look just like the parent plants because they are genetically identical to the parent plant.
This is because the cutting or callus that is used to start the new plant contains all of the genetic information of the parent plant, including the information that controls the plant's growth and development. This means that the new plant will have the same characteristics, such as leaf shape, flower color, and overall growth habit, as the parent plant. This process is called vegetative reproduction, where a part of a plant, such as a stem cutting, is used to propagate a new plant. The new plant is genetically identical to the parent plant because it has the exact same set of chromosomes, which is responsible for determining the plant's characteristics. This is different from the sexual reproduction where new plant is formed by the fusion of sperm and egg cells which can lead to genetic variation.

The thick, hardened layers of skin known as calluses and corns form when the skin tries to protect itself from pressure and friction. They typically appear on the fingers, hands, or toes and feet. The calluses and corns can look unpleasant.
The pressure and friction that result from wearing improperly fitting shoes, skipping socks, and using hand tools or musical instruments are the main contributors to the development of corns and calluses. Thus, it can be claimed that an increase in the production of epidermal cells causes the development of calluses and corns.
A section of a plant used in horticulture for vegetative (asexual) propagation is known as a plant cutting. A portion of the donor plant's stem or root is placed in a suitable medium, like damp soil. If the circumstances are right, the plant fragment will start to grow as a separate plant without the help of the parent plant, a process known as striking. New roots and stems are produced through root and stem cuttings, respectively. Some plants can be propagated via leaf fragments, often known as leaf cuttings, which develop both stems and roots. Cuttings are another name for the scions used in grafting.

They are also home to 2,000 species of plants and animals, and have an average elevation of 600 meters above sea level.
The Galapagos Islands' unique environment has led to the evolution of many different species that would not otherwise have been able to survive in their original habitats.

Peroxisomes are able to import folded proteins. Yet, these same organelles are impermeable to relatively small molecules such as NADH and acetyl-CoA. How is it possible to be permeable to one and not the other
Answers
Peroxisomes are able to import folded proteins by using the peroxisomal targeting signal-1 (PTS1) and peroxisomal targeting signal-2 (PTS2) sequence that is located on the C-terminus and N-terminus of the folded protein, respectively.
These signals allow the folded proteins to be recognized by the receptor proteins and to be imported into the peroxisomes by using a translocation mechanism, known as peroxisomal importomer.However, the peroxisomal membrane is impermeable to NADH and acetyl-CoA due to the presence of two specific proteins that are responsible for transporting NADH and acetyl-CoA. These proteins are called NADH and acetyl-CoA transporters, respectively. These transporters act as a selective gate that allows only NADH and acetyl-CoA to enter the peroxisomal matrix, while preventing other molecules from entering.
This selectivity is due to the specific shape and charge of the transporters that are designed to recognize and transport only NADH and acetyl-CoA. Therefore, the peroxisomes are able to import folded proteins, while maintaining the selective permeability to NADH and acetyl-CoA by using different mechanisms and transporters.

In the process of protein synthesis, the first builds RNAs and the second builds proteins. The correct option is A.
What is protein synthesis?Cells create proteins through a process known as protein synthesis. Transcription and translation take place simultaneously.
The conversion of genetic information from DNA to mRNA in the nucleus is known as transcription. Initiation, elongation, and termination are its three stages.
Creating a polypeptide, or protein consisting of a chain of amino acids, is the sole goal of protein synthesis. Keratin, a protein, is produced in the cells of the hair follicle.
In the first stage, messenger RNA (mRNA) is created. After leaving the nucleus, mRNA moves into the cytoplasm and joins a ribosome.
At this time, the second stage of translation starts, during which a specific protein molecule is created by reading the genetic instructions contained in the mRNA molecule.
Thus, the correct option is A.
