Bacteria living deep within the Earth's crust would use chemosynthesis, a type of cellular respiration, to obtain energy. They use inorganic materials to generate energy because light for photosynthesis doesn't reach these depths.
The bacteria found deep within the Earth's crust would likely rely on a process called chemosynthesis to obtain energy. Unlike photosynthesis, which uses sunlight for energy, chemosynthesis utilises chemicals from the surrounding environment. It's a kind of cellular respiration where energy is generated from inorganic substrates. In the deep parts of the Earth's crust, light doesn't penetrate, making it impossible for photosynthesis to occur. Instead, bacteria can obtain energy by converting inorganic materials, like iron, sulfur, and other minerals, into usable energy. Therefore, the correct answer is A. Cellular Respiration.

Scientists have recently modified the bacteria that causes tooth decay by inserting a fragment of DNA into the bacteria's DNA that prevents it from producing lactic acid. The new DNA is called recombinant DNA.
DNA is defined as deoxyribonuclic acid and it is a polymer made up of two polynucleotide chains that arranged in foiled structure to form a double helix carrying genetic information for the various processes such as growth development functioning and reproduction.
There are four nitrogen bases of DNA nucleotides are such as adinine, thymine, guanine and cytosine.
Friedrich miescher discovered DNA in the year of 1860.Scientists have recently modified the bacteria that causes tooth decay by inserting a fragment of DNA into the bacteria's DNA that prevents it from producing lactic acid. The new DNA is called recombinant DNA.
The main function of DNA is to carry information from one generation to another generation this is the reason due to which DNA is also known information molecule.
In our body DNA is found in the nucleus of the cell and it is known as nuclear DNA.
The shape of DNA is double helical structure.Scientists have recently modified the bacteria that causes tooth decay by inserting a fragment of DNA into the bacteria's DNA that prevents it from producing lactic acid. The new DNA is called recombinant DNA.
Siblings share only about 50% of same DNA due to the reason of recombination.
The life span of DNA is 521 years.There are four nitrogen bases of DNA nucleotides are such as adinine, thymine, guanine and cytosine.

Answer:
Dinosaurs are the extinct organisms that belong to the class reptilia. Dinosaurs are the most advanced and bulkier reptiles at the history time and they were overspecialized in their environment.
The dinosaurs extinct rapidly due to the change in the external conditions and the volcanic eruptions that occur at the dinosaurs time. The recent searcher claims that asteroid impact and massive volcanic eruption leads to the dinosaur extinction. The fossil evidence and the presence of the specific basalt and other chemicals are found in the volcanoes and in the asteroid.

A. The cells divide more frequently.
B. The cells use more energy.
C. The cells store more nutrients.
D. The cells degrade more proteins.
Some cells have more mitochondria because the cells use more energy. The correct option is B.
Mitochondria are the powerhouse of the cell. It is a long cylindrical organelle. Some cells contain more mitochondria than others because they require more energy. The mitochondria store energy for the function of the cell.
So, for example, the muscle contains a lot of mitochondria, as does the liver, the kidney, and, to some extent, the brain, which runs on the energy that those mitochondria make.
Depending on the function of thecell, several mitochondria are frequently found in one cell. Mitochondria, like other organelles, are found in the cytoplasm of cells.
Therefore, the correct option is B. The cells use more energy.

Minerals must have a definite chemical composition which may differ within specified limits. According to geologists minerals must be:
>naturally occurring-meaning, people did not make it.
Answer: Minerals must be homogenous.
