Answer the following question given this paragraph: Each kind of pigment absorbs specific wavelengths (colors) of light (dashed lines). Sunlight contains many different wavelengths, which you see when they separate into a rainbow. Not all colors of light are used in photosynthesis (solid line). Most plants, algae, and photosynthetic bacteria appear green because they reflect green wavelengths. Their pigments have absorbed the violet-blue and red wavelengths. The amount of photosynthesis depends on the wavelength of light available. Beta-carotene is another type of pigment that absorbs sunlight. Q: Sunlight contains many different wavelengths, which you see when they separate into what? Choices: - shadows - charges - sounds - rainbow A:
rainbow
Answer the following question given this paragraph: Eutherians are the most widespread of the mammals, occurring throughout the world. There are several groups of eutherians, including Insectivora, the insect eaters; Edentata, the toothless anteaters; Rodentia, the rodents; Chiroptera, the bats; Cetacea, the aquatic mammals including whales; Carnivora, carnivorous mammals including dogs, cats, and bears; and Primates, which includes humans. Eutherian mammals are sometimes called placental mammals, because all species have a complex placenta that connects a fetus to the mother, allowing for gas, fluid, waste, and nutrient exchange. While other mammals may possess a less complex placenta or briefly have a placenta, all eutherians have a complex placenta during gestation. Primates Order Primates of class Mammalia includes lemurs, tarsiers, monkeys, and the apes, which include humans. Non-human primates live primarily in tropical or subtropical regions of South America, Africa, and Asia. They range in size from the mouse lemur at 30 grams (1 ounce) to the mountain gorilla at 200 kilograms (441 pounds). The characteristics and evolution of primates are of particular interest to us as they allow us to understand the evolution of our own species. All primate species have adaptations for climbing trees, as they all descended from tree-dwellers, although not all species are arboreal. This arboreal heritage of primates resulted in hands and feet that are adapted for brachiation, or climbing and swinging through trees. These adaptations include, but are not limited to 1) a rotating shoulder joint, 2) a big toe that is widely separated from the other toes and thumbs that are widely separated from fingers (except humans), which allow for gripping branches, and 3) stereoscopic vision, two overlapping visual fields, which allows for the depth perception necessary to gauge distance. Other characteristics of primates are brains that are larger than those of many other mammals, claws that have been modified into flattened nails, typically only one offspring per pregnancy, and a... Q: Why are eutherian mammals sometimes called placental mammals? Choices: - identical placental connection - reacts placental connection - minor placental connection - complex placental connection A:
complex placental connection
Q: Answer the following question given this paragraph: Learned behavior is any behavior that occurs only after experience or practice. The more intelligent a species is, the more it depends on learned behaviors, which have the advantage of being flexible. Ways in which animals learn behaviors include habituation, observational learning, conditioning, learning through play, and insight learning. Q: What is the term for any behavior that occurs only after experience or practice? Choices: - practiced behavior - saved behavior - studied behavior - learned behavior A:
A: learned behavior
Question: Answer the following question given this paragraph: Q: What type of response do signal transductions within target cells bring about? Choices: - resporatory - bacterial - psychological - physiological A:
Answer: physiological
*Question*
Answer the following question given this paragraph: All the cells of your body need oxygen, which they get from red blood cells. Red blood cells, in turn, get oxygen in the lungs. The lungs are the main organs of the respiratory system. The respiratory system is the body system that exchanges gases with the outside air. It brings air containing oxygen into the body for the cells. It also releases carbon dioxide from the cells into the air. Q: Where do the cells in your body get oxygen from? Choices: - white blood cells - the digestive system - pores - red blood cells A:
**Answer**
red blood cells

Answer the following question given this paragraph: Many important crops, such as corn, are planted and harvested as seeds. These seeds are important sources of food. For example, corn is ground into feed for chickens and cows. And corn syrup is used to sweeten beverages and candy. But most importantly, seeds are the starting point for a new plant. Q: Many important crops, such as corn, are planted and harvested as what? Choices: - trees - cuttings - berries - seeds A:
(A).
seeds
