Explanation:
All medical research is carefully planned, and this includes medical
research with animals. Experts who review a scientist’s proposed
experiment involving animals weigh several considerations before
approving each study.
The most important thing is that the research must be relevant
to human or animal health. Studies need to protect the animals’
welfare. That means that only the fewest number of the most
appropriate species may be used. Under federal law, all animals
must be treated humanely and undergo the least distress possible

Since, it has a nervous system, blood vessels, and a long digestive tube is most likely a segmented worm.
<h3>What is a segmented worm?</h3>
Segmented worms have long tube-like bodies that are divided into segments.
They are the simplest organism with a true nervous system and blood contained in vessels.
They have a long digestive tube that runs down the length of the worm's inner body.
They can take in dissolved oxygen from the water through their skin.
Thus, a segmented worm has a nervous system, blood vessels, and a long digestive tube.

Yes, the all living tissues contains the catalase, Catalase protects cellular organelles and tissues from damage by peroxide.
<h3>
Do all living tissues contain catalase?</h3>
Catalase is a common antioxidant enzyme which is present in all living tissues of an organism and it is responsible for the degradation or reduction of hydrogen peroxide to water and molecular oxygen using either iron or manganese as a cofactor.
Liver, potatoes and other living tissues contain the enzyme catalase. This enzyme breaks down hydrogen peroxide which is a harmful by-product of the process of cellular respiration. If it builds up in concentration in the cells, the cells are adversely affected which leads to serious complications in the organisms.
So we can conclude that all living tissues contains the catalase, Catalase protects cellular organelles and tissues from damage by peroxide.
