Answer:
Spider has a circulatory system
Question:
What cell part contains an organism's genome?
Answer:
The nucleus
The features or characteristics of organic compounds include:
1. They contain covalent bonds and are mostly non polar in nature
2. Have lower boiling and melting points than inorganic compounds
3. Many organic compounds are thermally unstable, They decompose into simpler molecules when heated at fairly high temperatures
4. Most organic compounds are inflammable and burn exothermically in sufficient air to yield carbon dioxide, water and heat energy.
5. Most organic compounds being largely non polar are insoluble in water.
This was answered else where on Brainly, and this is what they said,
"Most proteins in the living organisms are enzymes and they required specific optimum conditions in order to function optimally. Disruption in the homeostasis will leads to deactivation of these proteins. For instance, if the temperature needed for a protein to work optimally has been exceeded, the protein may be denatured and will be unable to perform its needed functions, this may result in several adverse effects in the organism."
Answer:
In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.
