Answer:
When the soil of a plant runs too low of available water, the water chains in the xylem become thinner and thinner due to less water. Effectively, the plant is losing water faster than it is absorbing it. When this happens, the plant loses its turgidity and begins to wilt.
The term microevolution represents a predictive theory of how species might change with time.
The term macroevolution assumes that nature can create whole new structures and organisms simply be the environmental constraint.
Evolutionary biology, genetics, aetiology, genetics they overlap with the closely related sciences of ecology.
Ecology seeks to explain the movement of materials and energy through living communities, successional development of ecosystem and processes, adaptation and interactions.
Answer:
The model is in the annex
Explanation:
According to the model presented below, after the transition the RNA is in a state called pre-mRNA where we can see the presence of exons and introns. Introns are not sequences of nitrogenous bases that can participate in the production of proteins and therefore are removed from the RNA molecule through a process called splicing. Once the introns are removed, the mRNA is ready and leaves the nucleus towards the cytoplasm, by a process called exportation. Reaching the cytoplasm, the mRNA in association with the tRNA and the ribosomes will give rise to a polypeptide chain, in a process called translation, where the nitrogenous bases are transformed into amino acids.
The polypeptide chain has a linear sequence of amino acids. This chain will undergo several folds in a process called folding, where it will form a three-dimensional structure, the protein.
Search I’m safari there is the answer I think
Answer:
Option D, chloroplast
Explanation:
The process of photorespiration starts in the chloroplast when oxygen attaches to the RuBP. This produces three compounds namely – a) Three carbon compound (3-PGA) and b) Two carbon compound (phosphoglycolate). 3-PGA act as an intermediate to the Calvin cycle and before entering this cycle two of its carbon are removed. To recover lost carbon, plants taken in carbon through series of reactions involving phosphoglycolate. One fourth of the total carbon transported through this pathway is released as CO2. Since this entire process takes place in chloroplast, it can be said that CO2 is produced in chloroplast
Hence, option D is correct
