Scavengers play an important role in the network of food. They keep the world clean from the remains of dead animals, or carrion. Scavengers break down this raw material and recycle it as nutrients into the environment. Vultures consume only the corpses of deceased animals.
Lysosomes and chloroplasts are unique to plant cells.
Replication is performed prior to cell division
Answer:
this one`s been up for debate for awhile now.
1. it depends on the organism
learning about an organism could be considered 'easier' to study in different ways. for example, if you are studying marine life, you will most likely have to keep it in a water habitat to watch it alive. If you are studying a land species, then watching from it`s natural habitat will give you more accurate results. sometimes the environment can affect an organisms internal systems more than you may think. this leads into my second point.
2. it depends on what you are trying to study
if you are trying to learn about the mating process, seasonal activity, migration, or external behavior, then monitoring it from it`s natural habitat or an area that is a close copy is your best option. but if you are looking into studying internal organs/systems or cells, then in <em>most</em> cases, the organism will need to be taken out of its natural habitat. only in very careful situations is it left in a habitat during examination.
The first thing to do is activate
EMS. Use cool or cold water to cool the burn for 10 minutes as soon as
possible. ( Do not use ice or frozen compress.) Early cooling will minimize the
depth of injury and decrease pain. Remove jewelry near the affected area. Cover
the injury with dry, clean pad loosely
to protect it. Do not give food or drink to injured person. Keep him comfortable
until EMS arrives and takes over.
