The mineral is structured solid found in nature, with a fixed chemical composition. If a mineral scratches glass, the property hardness of the mineral is measured. The property hardness refers to the mineral's resistance to being scratched. In odrer to determine this property, scientists use the Moh's Hardness Scale. According this scale the mineral can be categorized as: <span>talc, gypsum, calcite, fluorite, apatite, orthoclase (feldspar), quartz, topaz, corundum or diamond.</span>

The mineral is structured solid found in nature, with a fixed chemical composition. If a mineral scratches glass, the property hardness of the mineral is measured. The property hardness refers to the mineral's resistance to being scratched. In order to determine this property, scientist see if the mineral can scratch certain objects such as glass, metal, nails, and coins.

A cell come a certain organism has 64 individual, or 32 pairs, of chromosomes. Which of these can you draw?
Dmitriy789 [7]

Answer:

B. The cell cannot be a human

Explanation:

Humans have 23 pairs of chromosomes, or 46 individual chromosomes. Mutations in humans usually cause there to be a single extra chromosome, or a single missing chromosome. A mutation would not cause there to be 64. So, A cannot be true. Prokaryotic cells usually have one chromosome, not 64, so C cannot be true. D cannot be assumed as you cannot tell if there is uncontrolled cell growth. Therefore, the answer would be B.

What is the potential problem for robotic rovers on Mars?
Step2247 [10]

Answer:

The limited  autonomy of the robotic rovers on Mars posed a big problem.

Explanation:

Missions are very costly, and can lead the project to fail with the simplest errors. If the rover was permanently trapped on a rock or destroyed, it would have a catastrophic impact on the exploration. Thus on-board technologies would still be more traditional than what a laboratory environment has sought. The autonomous rovers will considerably increase the productivity of  crew. Responsibility for their own well-being is also useful for the rovers: to prevent getting hurt, to recognize and correct recoverable hardware and software faults.
