entropy

Answer the following question given this paragraph: footprints, similar to those of modern humans, were found in Laetoli, Tanzania and dated to 3.6 million years ago. They showed that hominins at the time of Australopithecus were walking upright. There were a number of Australopithecus species, which are often referred to as australopiths. Australopithecus anamensis lived about 4.2 million years ago. More is known about another early species, Australopithecus afarensis, which lived between 3.9 and 2.9 million years ago. This species demonstrates a trend in human evolution: the reduction of the dentition and jaw in size. afarensis (Figure 29.42) had smaller canines and molars compared to apes, but these were larger than those of modern humans. Its brain size was 380450 cubic centimeters, approximately the size of a modern chimpanzee brain. It also had prognathic jaws, which is a relatively longer jaw than that of modern humans. In the mid-1970s, the fossil of an adult female A. afarensis was found in the Afar region of Ethiopia and dated to 3.24 million years ago (Figure 29.43). The fossil, which is informally called "Lucy," is significant because it was the most complete australopith fossil found, with 40 percent of the skeleton recovered. Q: What was the informal female name given to the adult fossil found in ethiopia and thought to be over 3 million years old? A:
OPTIONS:
- alice
- aunt
- linda
- lucy

Answer: lucy

Question: Answer the following question given this paragraph: Binary fission can be described as a series of steps, although it is actually a continuous process. The steps are described below and also illustrated in Figure below . They include DNA replication, chromosome segregation, and finally the separation into two daughter cells. Q: Dna replication, chromosome segregation, and the separation into two daughter cells are steps in what process? A:
OPTIONS:
- reproductive fission
- nuclear fission
- multiple fission
- binary fission
Answer: binary fission

input with options: Answer the following question given this paragraph: The double helical nature of DNA, together with the findings of Chargaff, demonstrated the base-pairing nature of the bases. Adenine always pairs with thymine, and guanine always pairs with cytosine ( Figure below ). Because of this complementary nature of DNA, the bases on one strand determine the bases on the other strand. These complementary base pairs explain why the amounts of guanine and cytosine are present in equal amounts, as are the amounts of adenine and thymine. Adenine and guanine are known as purines . These bases consist of two ring structures. Purines make up one of the two groups of nitrogenous bases. Thymine and cytosine are pyrimidines , which have just one ring structure. By having a purine always combine with a pyrimidine in the DNA double helix, the distance between the two sugar-phosphate backbones is constant, maintaining the uniform shape of the DNA molecule. Q: What distinctive configuration of dna demonstrates the base-pairing nature of the bases? A:
OPTIONS:
- single helix
- double loop
- triple helix
- double helix
output: double helix

Q: Answer the following question given this paragraph: Q: What functions as a framework that reinforces the shape of the leaf? A:

OPTIONS:
- the normal structure
- the central structure
- the stylised structure
- the vascular structure

A: the vascular structure

Answer the following question given this paragraph: Examples of Power Examples of power are limited only by the imagination, because there are as many types as there are forms of work and energy. (See Table 7.3 for some examples. ) Sunlight reaching Earth's surface carries a maximum power of about 1.3 kilowatts per square meter (kW/m 2). A tiny fraction of this is retained by Earth over the long term. Our consumption rate of fossil fuels is far greater than the rate at which they are stored, so it is inevitable that they will be depleted. Power implies that energy is transferred, perhaps changing form. It is never possible to change one form completely into another without losing some of it as thermal energy. For example, a 60-W incandescent bulb converts only 5 W of electrical power to light, with 55 W dissipating into thermal energy. Furthermore, the typical electric power plant converts only 35 to 40% of its fuel into electricity. The remainder becomes a huge amount of thermal energy that must be dispersed as heat transfer, as rapidly as it is created. A coal-fired power 6 plant may produce 1000 megawatts; 1 megawatt (MW) is 10 W of electric power. But the power plant consumes chemical energy at a rate of about 2500 MW, creating heat transfer to the surroundings at a rate of 1500 MW. (See Figure 7.25. Q: What does power imply is happening to energy? A:
OPTIONS:
- is expanding
- being destroyed
- being created
- being transferred
being transferred
