1. The mechanisms of heat loss contributing to Joel’s feelings of coldness are conduction‚ due to the loss of his hat somewhere on the trail and also his wet clothes; convention‚ which is happening because of the cold wind blowing; and lastly evaporation which is occurring as he breathes in the cold air and exhales it as warm moist air. 2. To help Joel maintain a normal body temperature‚ his body will begin to send signals to conserve and generate heat. This can be done through vasoconstriction

Gandhi once said‚ “The greatness of a nation and its moral progress can be judged by the way its animals are treated” (qtd. in Hajar). Animal testing is unnecessary and irrational because we have the technology to replace the inhumane testing‚ which proves to be even more accurate and precise with its

vascular plants. They function in the transport of water‚ nutrients‚ sugars‚ proteins and RNA throughout the plant. The xylem and phloem are generally found together in vascular bundles and can lie in various positions relative to each other. (Plant Vascular System Development) The term phloem originates from the Greek word‚ phloios‚ meaning “bark”. (Merriam-Webster) In vascular plants‚ phloem is the living tissue that carries organic nutrients‚ particularly sucrose‚ to all parts of the plant where
