Hey there!
Here are some observations you can make to conclude this is a fish:
~Gills
~Fins
~Scales
These three things normally tend to only be on fish. However, reptiles may have some of these characteristics as well.
Hope this helps!

Frogs have their way of avoiding the predators like camouflage, squirting the poisonous liquid out of their system and through their vestigial thumbs. This organ helps them by avoiding predation by stealth which makes them quiet and silent in moving so that predators won't notice them readily.
Answer:
Steroid hormones that enter the cell activate receptors. These hormone-receptor complexes then bind HREs and influence gene expression.
Explanation:
Mechanism of action of steroid hormones is as follows:
- Steroid hormone enters cell and bind to the receptor.
- Translocation of activated receptor- ligand complex into nucleus.
- This complex then bind to another receptor on the chromatin.
- Steroid receptors form dimers.
- Act on DNA
- These hormone-receptor complexes then bind HREs and influence gene expression.
- Augmentation or Suppression of transcription.
Phlebotomy refers to a collection of venous blood. This operation can be practiced on all the superficial veins of the body, on those of the foot, the leg, the neck, the whole upper limb. It must be done in an area where there is a protruding vein and the least sensitive to limit pain to the patient. It should not be done in an altered, injured or infected area (like bruise)
The blood is collected on tubes with or without anticoagulant according to the analyzes that one wants to practice.
The reason for choosing the sampling site is for the most part practical, the veins are easily identifiable, and easily accessible for paramedical personnel. Their collection is less dangerous than that of arteries, which are generally thinner and close to the peripheral nerves.
