It's easy to say "ooo fossils" but as far as what kind goes I would say cave drawing and marking have proven to show their was life back then. (I have no clue if this helps)
Your answer is A. True
Hope this helps.
Explanation:
Contamination can have undesirable consequences in real experiments, some of them are related to the feelings that may arise in the research participants, the contamination bias reduces the differences between the research groups, and can cause a comparison between the treatments of each different group, the which can generate conflicts and rivalries on the part of groups that consider themselves to be inferior to others. These contamination-related problems can significantly interfere with the research results.
Technology is basically a body of knowledge used to create tools, develop skills, and extract or collect materials. Now of course there are many pros and cons of technology. One pro is that it’s gets stuff done faster a con is that some people loose their jobs because a machine can do it so why does a person need to do it.
<span>There are two types of reproductive strategies: r and k
r- strategy is the type of organism that makes alot of babies. They have limited to no parent care. They also have a high death rate, but matures rapidly. The growth curve would be exponential like X^2.
For example: Think r for RATS because even if you think you killed all the rats, there are constantly making more.
k-strategy is the type of organism that makes a single or few babies. The give alot of attention/parent care. They mature slow, and low death rate. The growth curve is sigmuodial. The have a limited to how much species live in that environment called the carrying capacity. Carrying capacity = maximum of # of population within an environment (food, living space, etc).
For example: Think K for Kangaroo. </span>
