The correct answer is option D: ribosomes translate DNA code to RNA code.
During protein synthesis, ribosomes translate DNA code to RNA code.
Universally, ribosomes are responsible for the synthesis of proteins through the translation of genetic information with the help of mRNA as they code particular amino acids which are the key units of protein synthesis.
These are manufactured as a result of the processing of genetic code into messenger RNA i.e. mRNA through triplet RNA basis known as codons.
Moreover, ribosomes also function as catalysts to accelerate the process of protein formation by continuously supplying amino acids to the polypeptide chain.
During this reaction, transfer RNA i.e. tRNA server as a carrier of amino acids to ribosomal sites where translation of DNA code to RNA code occurs for protein synthesis.

Why do some plants remove water from their cells to reduce the amount of water that freezes inside them during winter?
a. The frozen water constricts organelles and causes plant cells to shrink.
b. As water contracts during freezing, the cells pull away from each other causing damage.
c. Less water in the cells means the cells are smaller and need to do less work.
d. The expansion of water as it turns to ice inside the cells would break the cells apart.
Answer:
b. As water contract during freezing the cells pull away from each other causing damage
[tex]\Large \boxed{\sf D}[/tex]
The cells would split apart due to the expansion of extra water when it freezes inside them. The liquid inside the cells can freeze and expand when the temperature drops below 0°C. The crop becomes unproductive as a result of the cells breaking.

It is true that algal blooms, and the rapid proliferation of photosynthetic plankton can ultimately end up depleting all the oxygen from a body of water.
What is algal bloom?Algal bloom is the dense spread of algae on the surface of water. Algal bloom is caused by a process called eutrophication.
Eutrophication is the ecosystem's response to the addition of artificial or natural nutrients, mainly phosphates, through detergents, fertilizers, or sewage, to an aquatic system.
The proliferation of algal species will result in the increase in the number of decomposers such as bacteria when the algae die. This decomposers will make use of oxygen excessively causing a decline.

This model best represents the role of carbon dioxide in trapping heat from radiation in the green house effect.
What is the green house effect?
By means of "greenhouse gases," heat is held in close proximity to the Earth's surface, creating the greenhouse effect. The world is kept warmer than it would be without the help of these heat-trapping gases, which act as a blanket surrounding the planet.
Most of the sun's visible light can travel through the atmosphere and reach the surface of the Earth. When sunlight heats the Earth's surface, some of the energy is radiated back into space as infrared radiation. Contrary to visible light, this radiation has a tendency to be absorbed by the greenhouse gases in the atmosphere, increasing its temperature. Infrared radiation is sent back toward the surface of the Earth by the heated atmosphere. (Despite its name, the greenhouse effect is not the same as the warming in a greenhouse, where glass panes transmit visible sunlight but hold heat inside the building by trapping warmed air.)

List the energy saving adaptations that help aquatic amphibians manage the challenges of living in a dilute environment as efficiently as possible.
The majority of aquatic amphibians have a short Loop of Henle, which lessens mineral and water absorption. Water thus enters the kidney tubules directly.
Ammonia a safe waste product for amphibians :Ammonia is simple to excrete because it is small and easily diffuses through cell membranes. In essence, there is a trade-off between easy excretion and levels of toxicity. Due to the abundance of water available to diluted ammonia wastes, toxicity is minimal for aquatic animals.

What is PCR?The polymerase chain reaction (PCR) is a technique that is frequently used to quickly create millions to billions of copies (complete or partial) of a specific DNA sample. This technique enables researchers to take a very small DNA sample and amplify it (or a portion of it) to a large enough quantity to study in detail. The PCR method of DNA manipulation was created in 1983 by American biochemist Kary Mullis at Cetus Corporation.

Which sentence best describes the production of the energy carried NADPH by the light reactions?
Photons of light are absorbed by electrons in NADPH, increasing its energy.
Why are photons of light are absorbed by electrons in NADPH?Although it operates similarly, photosynthesis requires the distinct fuel NADPH. A high-energy electron and proton are taken up by the low-energy form NADP+ and transformed into NADPH. NADPH changes back to NADP+ when one electron is lost. Overall, this process transforms light energy into chemical energy in the form of ATP and NADPH.
The Calvin cycle, the following stage of photosynthesis, uses ATP and NADPH from the light-dependent process to produce carbohydrates. Two electron transport chains work together to make ATP and NADPH. During the photoreaction, oxygen and water are both consumed. Since the process starts with sunlight, these reactions can only occur in the sun. the moment the photosystem is reached by an electron from the electron transport chain.

One of the most prevalent minerals on Earth is sodium chloride (NaCl), more generally known as salt. Many animals and plants require salt as nutrition. Seawater and subterranean rock formations both naturally contain sodium chloride.
Salts are ionic substances in chemical language. Most people understand salt to be the sodium chloride compound found in table salt. Ionic bonds between sodium ions and chloride ions produce sodium chloride. NaCl is the chemical formula because there is one sodium cation (Na+) for every chloride anion (Cl-).

Plants and animals are part of all of the nutrient cycles through the foods they eat and what eats them. name four classes of organic compounds contain carbon and explain how the carbon cycle and nitrogen cycle contribute to the usable supplies of the macromolecules.
Four classes of organic compounds containing carbon are carbohydrates, proteins, lipids, and nucleic acids. The carbon cycle involves photosynthesis which gives proteins to plants and animals. plants get their carbon from the air and their nitrogen from the soil.
Every living thing contains organic molecules like lipids, proteins, carbohydrates, and nucleic acids. Large carbon-based structures make up these macromolecules.
Living things use carbohydrates as a significant source of energy. Glucose, fructose, sucrose, galactose, ribose, deoxyribose, cellulose, and chitin are a few examples of carbohydrates.Lipids (Fats) Lipids are molecules that store a lot of energy. In comparison to carbohydrates, lipids store twice as much energy per gram.Amino acids are what make up proteins. The primary building elements of organisms are proteins. Large, intricate molecules called proteins are the building blocks of many different biological elements, including muscle fibers, enzymes, and hemoglobin.RNA and DNA are nucleic acids. The genetic code for producing proteins, specifically, is carried by DNA.Carbon is shared between living things and their environment during the carbon cycle. It describes how carbon moves when it is recycled and used again. Since carbon is the primary component of biological compounds, it is crucial for photosynthetic organisms to absorb carbon dioxide (CO₂) from the atmosphere, use it to make organic molecules like carbohydrates, lipids, proteins, and nucleic acids, and then release it back into the atmosphere as CO₂ during respiration.
On the other hand, plants cannot absorb nitrogen from the atmosphere in the form of the gas N₂. It is transformed by bacteria into ammonia (NH₃), a type of nitrogen that plants may use, as part of the nitrogen fixation process. Animals ingest useable nitrogen molecules when they consume plants.
