<h2>The given statement is true</h2>
Explanation:
The recent finding of the fossils which showed that <em>Homo erectus</em> and <em>Homo habilis</em> lived side by side in eastern Africa for perhaps half a million years challenged the conventional way that these two species evolved one after the other(<em>H.habilis</em> 1.44 million years old and <em>H.erectus </em>1.55 million years old)
- The fossils were found in Kenya and took years to prepare the specimens for study and to be sure of the identification of the species, the scientists said
- University of Utah geologists determined the dates of the fossils from volcanic ash deposits
- The most recent <em>Homo habilis</em> that had been known was about the same age as the earliest <em>Homo erectus</em><em>,</em> said Daniel Lieberman, a professor of biological anthropology at Harvard University, “Now we have extended the duration of the habilis species, and there’s no doubt that it overlaps considerably with erectus”
- The fact that the two hominid species lived together in the same lake basin for so long and remained separate species, Meave Leakey said in a statement from Nairobi, “suggests that they had their own ecological niche, thus avoiding direct competition”
Answer:
chips made from silicon
Explanation:
Non renewable resources are natural substances that cannot be replenished when used for eg natural gas, coal, petroleum ,fossil fuels etc. Silicon is made when silica is heated with carbon after which the the product is reacted with hydrocarbons to polymerize them. Since the hydrocarbons are made from natural gas, oil ,it is non renewable

<h2>1) option is correct </h2>
Explanation:
- Aspirin is contraindicated in a patient who is on oral anticoagulant medication because aspirin intensifies the action of the anticoagulant, which results in bleeding
- Bleeding from shaving cuts may be difficult to control, so the patient should be advised to use an electric razor only
- Patients who are on oral anticoagulant medication have difficulty controlling bleeding from injuries or external hemorrhage
- The nurse should teach the patient techniques such as the application of pressure to control bleeding
- Dental extraction may cause bleeding, which may be uncontrollable for a patient who is on anticoagulant medication, so patients on such type of medication should inform the dentist before starting the treatment
