Answer:

The correct answer is "photorespiration".

Explanation:

Photorespiration is a process in plants, where molecular oxygen is taken in a light-dependent  manner. Photorespiration is often considered a wasteful pathway because it competes with the Calvin cycle, which is much more efficient. In C3 plants the conservation of water promotes photorespiration. This occurs when the C3 plants close its stomata because the environment its too hot, or the carbon dioxide concentration drops to about 50 ppm.

As temperature increases, density decreases. This is because the particles have more energy, and spread out, which causes the density to decrease. When the particles spread out, it can also lead to the object changing states. The same effect is seen when the temperature decreases. The particles slow down, have less energy, and go closer together. When the particles come together, it can also lead to an object changing states.

As temperature increases, density decreases. This allows a hot air balloon to fly because the air in the balloon is heated which makes the air in the balloon less dense then the air around the balloon. Less dense air goes up and denser air goes down so this is why the balloon fly. The design of the balloon is related to thermal energy because as the temperature rises the balloon expands.

Type III PKS (Polyketide Synthase) enzymes play a crucial role in the biosynthesis of various secondary metabolites in both plants and bacteria.

These enzymes are responsible for the production of a diverse range of compounds with important biological functions. Understanding the evolutionary mechanisms and functional diversity of Type III PKS enzymes can provide insights into the evolution and biological significance of these metabolites.

Type III PKS divergence refers to the evolutionary processes that lead to the diversification of Type III PKS enzymes within and between different species. These mechanisms can include genetic mutations, gene duplications, gene losses, and natural selection acting on the genes encoding Type III PKS enzymes.

Currently, twelve functionally divergent Type III PKS enzyme families have been identified in plants, along with three families in bacteria. Each family of Type III PKS enzymes exhibits specific biological functions and activities, leading to the synthesis of distinct secondary metabolites. These metabolites can have various roles, such as defense against pathogens, UV protection, pigmentation, and signaling.

Studying the evolutionary mechanisms and functional diversity of Type III PKS enzymes provides valuable insights into the adaptation and specialization of organisms, as well as the potential for discovering novel bioactive compounds with pharmaceutical or agricultural applications.

Body composition is a term used often by doctors and health professionals. It refers to the percentage of fat, bone, and muscle in your body. Doctors use body composition to see if you’re at a healthy weight for your individual body.

Explanation:

Errors in transcription or translation can be offset by the redundancy of the genetic code. The codon chart displayed on the previous page shows that each amino acid is coded for by multiple different codons. This redundancy helps to reduce the likelihood of errors in translation or transcription.

For example, Alanine can be coded for by four different codons: GCU, GCC, GCA and GCG. This means that if a mutation occurs in the coding strand of DNA, such as a single base substitution, the new codon may still code for Alanine. As a result, the amino acid sequence will not be changed and the protein product of the gene will remain the same. This is known as a silent mutation and it can offset errors in transcription or translation.

The redundancy of the genetic code also helps to reduce the chances of errors occurring during translation. This is because, if a codon is misread, the cell can still recognize the correct amino acid. For example, if a cell misreads the codon for Alanine (GCA) as GAA, the cell will still recognize the correct amino acid because GAA is the codon for Glutamic Acid. This means that the protein product of the gene will remain the same.

In conclusion, the redundancy of the genetic code helps to offset errors in transcription and translation by allowing single base substitutions to go unnoticed and allowing codons to be misread without changing the amino acid sequence of the protein product.
