Answer:
Question: Two requirements for gas exchange which are accomplished by the gills in a fish include:
1. Water flowing in opposite directions across the gill lamellae for gas exchange, in other words, respiration is experienced by the fish.
2. The fish allows water through its mouth, then forces the water to drain through the gills supporting gill lamellae, and enhancing gas exchange.
Question: How does their structure help to satisfy these requirements?
1. The rows of gill filaments with numerous folds through diffusion makes sure oxygen from the water moves from a place of more concentration to the blood of the fish which has less concentration causing the removal of carbon dioxide.
2. The large surface area of the gill means it has to maximize the low percentage of dissolved oxygen in the water compared to the higher percentage of oxygen in the air makes it possible for water to pass through the mouth and empty through the gills after the mouth is closed.
Both are under the phylum annelida
Polychaeta are more numerous than oligochaeta
Example of polychaeta is sand worm
While oligochaeta is earth worm
Both are free living organisms
Answer:
Yes, it has.
Explanation:
Replicability of an experiment holds great importance in the scientific world. Different groups of scientists ought to be able to replicate a certain experiment to achieve the same results/conclusions as the first team of scientists did. This is essential to prove that the findings are credible and did not just occur by chance, which is the case here too.
Answer:
B. an amino terminal signal peptide
Explanation:
The reactions of the citric acid cycle occur in the matrix of mitochondria. Therefore, all the enzymes required for this pathway are present in the matrix of mitochondria. These enzymes are formed on the ribosomes present in the cytosol and are transported into the mitochondria with the help of cytosolic heat shock proteins. The newly formed mitochondrial proteins have signal sequences present at their N terminal. The proteins to be transported into the matrix have a single signal sequence that at N terminal which is removed by a protease once the enzyme enters into the matrix.
