A woodcutter could justify cutting trees for use say in a pioneering situation whereby the pioneer needs shelter and food so trees could be necessary to say construct a small log cabin and table for eating/preparing food at to ensure the survival of the pioneer.
Answer:
Tilapia is one of the most productive and internationally traded food fish in the world. The production of farmed tilapia is among the fastest expanding food sectors in the world. Nile tilapia ( Oreochromis niloticus) is the most cultured freshwater species among the farmed tilapia and contributes about 71% of the world total tilapia production.
Tilapia is one of the most important farmed fish species worldwide (FAO 2018) and an important source of protein (Fitzsimmons 2000;Hai 2015). Due to its sequenced genome (Conte et al. 2017), easy reproduction, efficiency in adapting to diverse diets, high resistance to diseases and handling practices, and high tolerance of a wide variety of husbandry conditions, it is considered an ideal model in toxicological research.

The interpretation of bodily pain and touch also involves the parietal lobe.
<h3>What area of the brain is responsible for controlling movement and pain perception?</h3>
The eyes, face, and mouth may all move thanks to the brainstem. Additionally, it sends sensory information (such hot, painful, and noisy) and regulates breathing, awareness, heart function, and uncontrollable muscular movements like sneezing, coughing, vomiting, and swallowing. Cerebellum. This area of the brain is the back.
<h3>The brain's mechanism for detecting touch?</h3>
Sensitivity to touch and cortical maps
Initial impulses from sensations are produced by touch receptors in your skin. They move along sensory nerves made of bundled fibers that are linked to spinal cord neurons. After that, information is transmitted to the thalamus, which in turn informs the rest of the brain.

Answer:
A pair of nephridia is present on each segment of the earthworm, They are similar to flame cells in that they have tubules with cilia and function like a kidney to remove wastes.
Explanation:
The reasons are:
- the blood is very low on nutrition
- the leech is not feeding itself regularly
The leech slows it metabolism a lot, so it can survive on very low nutrition. The blood is very low on nutrition, and it is the leech's food source, so the evolution made it preserve energy.
The leach doesn't have the opportunity to feed itself on regular basis, so it takes maximum advantage of any opportunity and consumes as much blood as possible so that it can survive long term when it will not have food at disposal.
