Answer the following question given this paragraph: Migration refers to seasonal movements of animals from one area to another. Migrants typically travel long distances, and travel the same paths each seasonal cycle. Usually, the migrants move to another area in order to find food or mates. Many birds, fish, and insects migrate. Mammals such as whales and caribou migrate as well. Figure below shows the migration route of a bird called a godwit. Another example of a behavior with a yearly cycle is hibernation. Hibernation is a state in which an animal's body processes are slower than usual, and its body temperature falls. An animal uses less energy than usual during hibernation. This helps the animal survive during a time of year when food is scarce. Hibernation may last for weeks or months. Animals that hibernate include species of bats, squirrels, and snakes. Most people think that bears hibernate. In fact, bears do not go into true hibernation. In the winter, they go into a deep sleep. However, their body processes do not slow down very much. Their body temperature also remains about the same as usual. Bears can be awakened easily from their winter sleep. Q: The seasonal movements of animals from one area to another is referred to as? Choices: - mitigation - hybernation - echolocation - migration A:
migration
Answer the following question given this paragraph: Whereas cystic fibrosis, Tay-Sachs, and phenylketonuria are all autosomal recessive disorders, achondroplasia is an autosomal dominant disorder. Achondroplasia is the most common cause of dwarfism in humans. Achondroplasia is a result of an autosomal dominant mutation in the fibroblast growth factor receptor gene 3 (FGFR3), which causes an abnormality of cartilage formation. FGFR3 normally has a negative regulatory effect on bone growth. In achondroplasia, the mutated form of the receptor is constitutively active (constantly "turned on") and this leads to severely shortened bones. Individuals with achondroplasia are heterozygous for the mutation (one mutant copy, one normal copy). Homozygous for the achondroplasia mutation is lethal prior to birth or shortly after birth. Q: What is the most common cause of dwarfism? Choices: - deformity - hypothyroidism - retinopathy - achondroplasia A:
achondroplasia
Q: Answer the following question given this paragraph: 8.3 The Pelvic Girdle and Pelvis The pelvic girdle, consisting of a hip bone, serves to attach a lower limb to the axial skeleton. The hip bone articulates posteriorly at the sacroiliac joint with the sacrum, which is part of the axial skeleton. The right and left hip bones converge anteriorly and articulate with each other at the pubic symphysis. The combination of the hip bone, the sacrum, and the coccyx forms the pelvis. The pelvis has a pronounced anterior tilt. The primary function of the pelvis is to support the upper body and transfer body weight to the lower limbs. It also serves as the site of attachment for multiple muscles. The hip bone consists of three regions: the ilium, ischium, and pubis. The ilium forms the large, fan-like region of the hip bone. The superior margin of this area is the iliac crest. Located at either end of the iliac crest are the anterior superior and posterior superior iliac spines. Inferior to these are the anterior inferior and posterior inferior iliac spines. The auricular surface of the ilium articulates with the sacrum to form the sacroiliac joint. The medial surface of the upper ilium forms the iliac fossa, with the arcuate line marking the inferior limit of this area. The posterior margin of the ilium has the large greater sciatic notch. Q: The pelvic girdle, consisting of a hip bone, serves to attach a lower limb to this? Choices: - exoskeleton - appendicular skeleton - cytoskeleton - axial skeleton A:
A: axial skeleton
Question: Answer the following question given this paragraph: One common example of an extra-chromosome disorder is Down syndrome ( Figure below ). Children with Down syndrome are mentally disabled and also have physical deformities. Down syndrome occurs when a baby receives an extra chromosome 21 from one of his or her parents. Usually, a child will receive one chromosome 21 from the mother and one chromosome 21 from the father. In an individual with Down syndrome, however, there are three copies of chromosome 21 ( Figure below ). Therefore, Down syndrome is also known as Trisomy 21. These people have 47 total chromosomes. Q: What's the most common disorder from having an extra chromosome? Choices: - Williams syndrome - Turner syndrome - cri-du-chat syndrome - down syndrome A:
Answer: down syndrome
*Question*
Answer the following question given this paragraph: The answer depends on if the cell is prokaryotic or eukaryotic. The main difference between the two types of cells is the presence of a nucleus. In eukaryotic cells, DNA lives in the nucleus. Q: What is the main difference between prokaryotic and eukaryotic cells? Choices: - enlarged mitochondria - presence of cytoplasm - absence of cytoplasm - presence of a nucleus A:
**Answer**
presence of a nucleus
Q: Answer the following question given this paragraph: Q: What is used to date older fossils? Choices: - search engines - litmus testing - electron microscopes - radioactive isotopes A:
A: radioactive isotopes
