Answer the following question given this paragraph: A protein is an organic compound made up of small molecules called amino acids . There are 20 different amino acids commonly found in the proteins of living things. Small proteins may contain just a few hundred amino acids, whereas large proteins may contain thousands of amino acids. Q: What is an organic compound made up of small molecules called amino acids called? Choices: - a carbohydrate - a fat - a compound - a protein A:
a protein
Answer the following question given this paragraph: Transgenic Animals Although several recombinant proteins used in medicine are successfully produced in bacteria, some proteins require a eukaryotic animal host for proper processing. For this reason, the desired genes are cloned and expressed in animals, such as sheep, goats, chickens, and mice. Animals that have been modified to express recombinant DNA are called transgenic animals. Several human proteins are expressed in the milk of transgenic sheep and goats, and some are expressed in the eggs of chickens. Mice have been used extensively for expressing and studying the effects of recombinant genes and mutations. Q: Animals that have been modified to express recombinant dna are called what? Choices: - reproducing animals - mammalian animals - aquatic animals - transgenic animals A:
transgenic animals
Q: Answer the following question given this paragraph: The process of cell division is how multicellular organisms grow and repair themselves. It is also how many organisms produce offspring. For many single-celled organisms, asexual reproduction is a similar process. The parent cell simply divides to form two daughter cells that are identical to the parent. Asexual reproduction produces offspring that are genetically identical to the parent, whereas sexual reproduction produces a similar, but genetically unique offspring. In sexual reproduction, meiosis produces haploid gametes that fuse during fertilization to produce a diploid zygote ( Figure below ). In other words, a child inherits half of the genetic material from each parent. Look at the family in Figure below . The children resemble their parents, but they are not identical to them. Instead, each has a unique combination of characteristics inherited from both parents. The children, of course, result from sexual reproduction. Q: What process of allows multicellular organisms to grow and repair themselves? Choices: - proteins division - atom split - DNA division - cell division A:
A: cell division
Question: Answer the following question given this paragraph: Look at the honeybees in Figure below . Honeybees live in colonies that may consist of thousands of individual bees. Generally, there are three types of adult bees in a colony: workers, a queen, and drones. Q: Adult bees include workers, a queen and what other type? Choices: - laborers - soldiers - builders - drones A:
Answer: drones

Answer the following question given this paragraph: Pelvis The pelvis consists of four bones: the right and left hip bones, the sacrum, and the coccyx (see Figure 8.12). The pelvis has several important functions. Its primary role is to support the weight of the upper body when sitting and to transfer this weight to the lower limbs when standing. It serves as an attachment point for trunk and lower limb muscles, and also protects the internal pelvic organs. When standing in the anatomical position, the pelvis is tilted anteriorly. In this position, the anterior superior iliac spines and the pubic tubercles lie in the same vertical plane, and the anterior (internal) surface of the sacrum faces forward and downward. The three areas of each hip bone, the ilium, pubis, and ischium, converge centrally to form a deep, cup-shaped cavity called the acetabulum. This is located on the lateral side of the hip bone and is part of the hip joint. The large opening in the anteroinferior hip bone between the ischium and pubis is the obturator foramen. This space is largely filled in by a layer of connective tissue and serves for the attachment of muscles on both its internal and external surfaces. Several ligaments unite the bones of the pelvis (Figure 8.14). The largely immobile sacroiliac joint is supported by a pair of strong ligaments that are attached between the sacrum and ilium portions of the hip bone. These are the anterior sacroiliac ligament on the anterior side of the joint and the posterior sacroiliac ligament on the posterior side. Also spanning the sacrum and hip bone are two additional ligaments. The sacrospinous ligament runs from the sacrum to the ischial spine, and the sacrotuberous ligament runs from the sacrum to the ischial tuberosity. These ligaments help to support and immobilize the sacrum as it carries the weight of the body. Q: Designed to support the weight of the upper body when sitting and transfer this weight to the lower limbs when standing, what body structure consists of four bones: right and left hip bones, sacrum, and coccyx? Choices: - tissues - Chest - lungs - pelvis A:
**Answer**
pelvis
Q: Answer the following question given this paragraph: Problem-Solving Strategies for the Effects of Heat Transfer 1. Examine the situation to determine that there is a change in the temperature or phase. Is there heat transfer into or out of the system? When the presence or absence of a phase change is not obvious, you may wish to first solve the problem as if there were no phase changes, and examine the temperature change obtained. If it is sufficient to take you past a boiling or melting point, you should then go back and do the problem in stepstemperature change, phase change, subsequent temperature change, and so on. Identify and list all objects that change temperature and phase. Identify exactly what needs to be determined in the problem (identify the unknowns). A written list is useful. Make a list of what is given or what can be inferred from the problem as stated (identify the knowns). Solve the appropriate equation for the quantity to be determined (the unknown). If there is a temperature change, the transferred heat depends on the specific heat (see Table 14.1) whereas, for a phase change, the transferred heat depends on the latent heat. See Table 14.2. Substitute the knowns along with their units into the appropriate equation and obtain numerical solutions complete with units. You will need to do this in steps if there is more than one stage to the process (such as a temperature change followed by a phase change). Check the answer to see if it is reasonable: Does it make sense? As an example, be certain that the temperature change does not also cause a phase change that you have not taken into account. Q: What is the term of a phase change if solid water has it's average kinetic energy increased to change it to liquid water? Choices: - boiling - freezing - evaporation - melting A:
A: melting
