Answer the following question given this paragraph: Geology is the study of the solid Earth. Geologists study how rocks and minerals form. The way mountains rise up is part of geology. The way mountains erode away is another part. Geologists also study fossils and Earth's history. There are many other branches of geology. There is so much to know about our home planet that most geologists become specialists in one area. For example, a mineralogist studies minerals, as seen in ( Figure below ). Q: What is the name of the scientific field that deals with the general study of the solid earth? A:

OPTIONS:
- astronomy
- physics
- chemistry
- geology

Answer: geology

- sinus
- diaphragm
- pharynx

Answer: pharynx

Problem:OPTIONS:
- abnormalities
- clusters
- chromosonal variations
- phenotypes

Answer the following question given this paragraph: Consider the following example: Suppose you have a purple and white flower and purple color ( P ) is dominant to white ( p ). The white flower must be homozygous for the recessive allele, but the genotype of the purple flower is unknown. It could be either PP or Pp . A testcross will determine the organism's genotype. The unknown genotype can be determined by observing the phenotypes of the resulting offspring. If crossing the unknown dominant phenotype ( PP or Pp genotype) individual with the recessive phenotype individual produces only dominant phenotypes (no recessive), then the unknown individual is homozygous dominant. If any recessive phenotypic individuals result from the cross, then the unknown individual must carry the recessive allele, and have the heterozygous genotype. Q: An unknown genotype can be determined by observing what, the term for characteristics of the resulting offspring? A:
****
A: phenotypes

Answer the following question given this paragraph: Q: Are birds and mammals mainly exothermic or endothermic? A:
OPTIONS:
- autotrophic
- hypothermic
- exothermic
- endothermic
endothermic

Answer the following question given this paragraph: Helicopter pilots are quite familiar with rotational kinetic energy. They know, for example, that a point of no return will be reached if they allow their blades to slow below a critical angular velocity during flight. The blades lose lift, and it is impossible to immediately get the blades spinning fast enough to regain it. Rotational kinetic energy must be supplied to the blades to get them to rotate faster, and enough energy cannot be supplied in time to avoid a crash. Because of weight limitations, helicopter engines are too small to supply both the energy needed for lift and to replenish the rotational kinetic energy of the blades once they have slowed down. The rotational kinetic energy is put into them before takeoff and must not be allowed to drop below this crucial level. One possible way to avoid a crash is to use the gravitational potential energy of the helicopter to replenish the rotational kinetic energy of the blades by losing altitude and aligning the blades so that the helicopter is spun up in the descent. Of course, if the helicopter's altitude is too low, then there is insufficient time for the blade to regain lift before reaching the ground. Problem-Solving Strategy for Rotational Energy 1. Determine that energy or work is involved in the rotation. Determine the system of interest. A sketch usually helps. Analyze the situation to determine the types of work and energy involved. For closed systems, mechanical energy is conserved. That is,. Q: Helicopter pilots can recover from piloting errors by decreasing altitude, turning some of their potential energy into what kind of energy? A:
OPTIONS:
- electrical
- free
- active
- kinetic

Answer:
kinetic
