Explanation:
The little dots collected from under the fern leaves are spores, not seeds. Ferns are different from seed-bearing plants in that ferns in a sexless way through sporophyte generation. Spores dropped from or taken from grown fern leaves have developed prothallium. Each prothallium generates male and female organs in what is called the gametophyte stage. When fertilization of the female gametophyte happens, small fern plants or leaflets start to grow.
<span> The answer is a misense mutation. In this case, the substitution of the tryosine amino acid with cysteine in the same position in the sequence does not affect the polypeptide becasue both tryosine and cysteine are polar animo acids. If the substitution </span><span><span> in the polypeptide chain </span>was by amino acids with different properties, it would affect the folding of the protein and change its conformation hence also affect its function. </span>
The correct answer is B. Electron transport.
The electron transport chain is the terminal step of aerobic respiration. It occurs on the inner membrane of the mitochondria. Reduced coenzymes NADH and FADH₂ are produced during glycolysis and Krebs cycle. When NADH and FADH₂ move along electron transport chains, high-energy electrons are released from NADH and FADH₂ produce ATP. The final electron acceptor in the process is free oxygen. Each NADH produces 3 ATP and each FADH₂ produces 2 ATP. Therefore, a total of 32 ATP molecules are generated in electron transport. Therefore, the electron transport system releases a lots of energy for cheetah to run fast.
Answer:
Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.
