Answer:
The process of photosynthesis converts light energy into stored chemical energy by converting carbon dioxide plus water into sugars plus released oxygen. ... As matter and energy flow through different organizational levels of living systems, chemical elements are recombined in different ways to form different products.

Answer:
somethings always different
Explanation:
Ans. 25.
Messenger RNA or mRNA has genetic information in the form of triplet codes, called as codons. These codons are made up of three nucleotide bases and each codon codes for a specific amino acid during protein synthesis.
According to codon chart, GCU codes for alanine (Ala), AAU codes for asparagine (Asn), and GUC codes for valine (Val). Thus, the amino acid sequence for the mRNA strand GCU - AAU - GUC is Ala-Asn-Val.
Ans. 26.
a). There are a total of sixty-four codons, made up of combinations of four nucleotide bases (4 X 4 X 4= 64). Out of sixty four codons, sixty one codons code for twenty amino acids that make proteins, while three codons (UAG, UGA, UAA) do not code for any amino acid and act as stop codons. Thus, no protein will be form with the mRNA strand UAG-UGA-UAA.
b). The UAG, UGA, and UAA are stop codons that act as signals to terminate the translation during protein synthesis. Thus, if a ribosome reads the mRNA sequence UAG, UGA, and UAA during translation, it will lead to termination of protein synthesis.
<span>The question is asking us to choose the order of increasing complexity and the correct answer is
(3) organelles → cells → tissues → organs. Organelles are parts of cells, for example a mitochondrium is an organelle. Many cells form tissues and tissues form an organ. Many organ for an organism, for example, a human being is an organism - that's the whole animal or plant. </span>
