Answer the following question given this paragraph: Fruit The seed forms in an ovary, which enlarges as the seeds grow. As the seed develops, the walls of the ovary also thicken and form the fruit. In botany, a fruit is a fertilized and fully grown, ripened ovary. Many foods commonly called vegetables are actually fruit. Eggplants, zucchini, string beans, and bell peppers are all technically fruit because they contain seeds and are derived from the thick ovary tissue. Acorns and winged maple keys, whose scientific name is a samara, are also fruit. Mature fruit can be described as fleshy or dry. Fleshy fruit include the familiar berries, peaches, apples, grapes, and tomatoes. Rice, wheat, and nuts are examples of dry fruit. Another distinction is that not all fruits are derived from the ovary. Some fruits are derived from separate ovaries in a single flower, such as the raspberry. Other fruits, such as the pineapple, form from clusters of flowers. Additionally, some fruits, like watermelon and orange, have rinds. Regardless of how they are formed, fruits are an agent of dispersal. The variety of shapes and characteristics reflect the mode of dispersal. The light, dry fruits of trees and dandelions are carried by the wind. Floating coconuts are transported by water. Some fruits are colored, perfumed, sweet, and nutritious to attract herbivores, which eat the fruit and disperse the tough undigested seeds in their feces. Other fruits have burs and hooks that cling to fur and hitch rides on animals. Q: Because they spread seeds, fruits are an agent of what? Choices: - propagation - disposal - predation - dispersal A:
dispersal

Answer the following question given this paragraph: neotropicum infects the ant Cephalotes atratus, leading to dramatic changes in the infected ant's morphology and behavior. The infected ant's abdomen turns red and is held raised up, which makes it resemble a fruit and increases the likelihood of the infected ant being eaten by birds (). The birds transport the worms, which survive in their digestive systems until they are excreted; they are then eaten by, and infect new ants to complete the worm's life cycle.78 Perhaps the most famous example of this type of behavior occurs in wasps of the family Ichneumonidae. Female wasps deposit their fertilized eggs into the bodies of various types of caterpillars. The wasp eggs hatch out and produce larvae which then feed on the living caterpillar, consuming it from the inside out. Charles Darwin, in a letter to the American naturalist Asa Gray, remarked "There seems to me too much misery in the world. I cannot persuade myself that a beneficent & omnipotent God would have designedly created the Ichneumonidae with the express intention of their feeding within the living bodies of caterpillars, or that a cat should play with mice. " Rather than presume that a supernatural creator was responsible for such apparently cruel behaviors, Darwin and others sought alternative, morally neutral naturalistic processes that could both generate biological diversity and explain biological behaviors. As the diversity of organisms became increasingly apparent and difficult to ignore, another broad and inescapable conclusion began to emerge from anatomical studies: many different organisms displayed remarkable structural similarities. For example, as naturalists characterized various types of animals, they found that they either had an internal skeleton (the vertebrates) or did not (the invertebrates). Comparative studies revealed that there were often many similarities between quite different types of organisms. A classic work, published in 1555, compared the skeletons of a human and a bird, both vertebrates.79 While many bones have... Q: Which infection turns ant's abdomen red and fruit-like and an easy prey for birds? Choices: - yeast - trichina - cocklebur - neotropicum A:
(Answer)
neotropicum
Ques: Answer the following question given this paragraph: Figure 10.14 The role of normal p53 is to monitor DNA and the supply of oxygen (hypoxia is a condition of reduced oxygen supply). If damage is detected, p53 triggers repair mechanisms. If repairs are unsuccessful, p53 signals apoptosis. A cell with an abnormal p53 protein cannot repair damaged DNA and thus cannot signal apoptosis. Cells with abnormal p53 can become cancerous. (credit: modification of work by Thierry Soussi). Q: Hypoxia is a condition of the reduced supply of what? Choices: - methane - food - nitrogen - oxygen A:
Ans: oxygen

Harmful bacteria will be discussed in another concept. Q: What would you call a relationship where the bacteria benefit and and the other organism is harmed? Choices: - pathology - fungi - symbiotic - parasitism A:
(A).
parasitism
Ques:Answer the following question given this paragraph: Figure 20.8 shows the schematic for a simple circuit. A simple circuit has a single voltage source and a single resistor. The wires connecting the voltage source to the resistor can be assumed to have negligible resistance, or their resistance can be included in R . Q: What has a single voltage source and a single resistor Choices: - complex circuit - pattern circuit - stuff circuit - simple circuit A:

Ans:simple circuit
Ques:Answer the following question given this paragraph: Oogenesis begins long before birth when an oogonium with the diploid number of chromosomes undergoes mitosis. It produces a diploid daughter cell called a primary oocyte. The primary oocyte, in turn, starts to go through the first cell division of meiosis (meiosis I). However, it does not complete meiosis until much later. The primary oocyte remains in a resting state, nestled in a tiny, immature follicle until puberty. Q: What begins when an oogonium with the diploid number of chromosomes undergoes mitosis? Choices: - germination - morphogenesis - gametogenesis - oogenesis A:

Ans:
oogenesis
