Which one of the following is true about the importance of Lucy in resolving debates about human evolution?

  1. A.Big brains came before bipedalism.
  2. B.Lucy had a brain size of 18% of her body mass.
  3. C.Bipedalism came before big brains.
  4. D.Lucy was partially an arboreal primate.
Deebii fi ibsa ilaalaa

Deebii: C Bipedalism came before big brains.

Maaliif

Lucy is a fossil of Australopithecus afarensis found in Ethiopia in 1974. Her leg, pelvis and spine show that she walked upright on two legs, yet her brain was still small, close to the size of a chimpanzee's brain.

Before her discovery, scientists argued about which came first: a big brain or upright walking. Lucy settled that debate. Bipedalism came before big brains, so option C is correct.

Which one of the following can best explain behavior? It is

  1. A.the co-ordinated response of an organism to an internal or externalstimuli.
  2. B.the tendency for parts of plants to grow towards light.
  3. C.the actions or reactions of a person or animal in response to external or internal stimuli.
  4. D.a cell or group of cells that receives and processes stimuli.
Deebii fi ibsa ilaalaa

Deebii: A the co-ordinated response of an organism to an internal or externalstimuli.

Maaliif

In biology, behavior is the coordinated response of an organism to internal or external stimuli. The word "organism" matters here: all living things behave, not only people and animals. Plants also respond to stimuli, for example by growing toward light.

Option C is tempting, but it limits behavior to persons and animals, so it is too narrow. Option B is only one plant example, and option D defines a receptor, not behavior.

Textbook: Biology Grade 11, Unit 2 Animals, section 2.5 Animal behavior.

Gaaffii 3

The quick withdrawal of your hand from a hot plate is an example of

  1. A.fixed action pattern.
  2. B.innate behavior.
  3. C.biological clock.
  4. D.key stimulus.
Deebii fi ibsa ilaalaa

Deebii: B innate behavior.

Maaliif

Pulling your hand away from a hot plate is a simple reflex: a sudden, involuntary response that does not have to be learned. Reflexes belong to innate (inborn) behavior, so B is correct.

A fixed action pattern is a complete sequence of instinctive actions, such as web building in spiders, not a single quick response. A biological clock controls repeating rhythms, and a key stimulus is the trigger of a behavior, not the behavior itself.

Gaaffii 4

Which one of the following processes describes a biological clock?

  1. A.Removal of one's thumb from hot objects quickly
  2. B.The growing of plants towards light
  3. C.Circannual migration of birds from temperature to tropical areas
  4. D.Kinenis and taxes of woodlice and other simple animals
Deebii fi ibsa ilaalaa

Deebii: C Circannual migration of birds from temperature to tropical areas

Maaliif

A biological clock is an internal timer that makes a behavior repeat on a regular cycle. Bird migration from temperate to tropical areas happens once every year, on a yearly rhythm called a circannual rhythm, so it is driven by a biological clock.

Hand withdrawal is a reflex, growth toward light is a plant tropism, and kinesis and taxis are simple orientation movements. None of these run on a timed cycle.

Textbook: Biology Grade 11, Unit 2 Animals, section 2.5.2 Patterns of behavior.

Gaaffii 5

Identify learned behavior from the following.

  1. A.Dog trained to hunt.
  2. B.Honey bee making honey.
  3. C.Child withdrawals hand from hot things.
  4. D.Ants making nest.
Deebii fi ibsa ilaalaa

Deebii: A Dog trained to hunt.

Maaliif

Learned behavior is gained through experience or training during an animal's own life. A dog hunts on command only because a person trained it, so this is learned behavior.

Making honey, pulling a hand away from heat and building nests are inborn abilities. The animals do them correctly the first time, without any training, so they are innate.

Gaaffii 6

Which one of the following features is unique to bacteria?

  1. A.Presence of permeable membrane
  2. B.Being unicellular
  3. C.Absence of nuclear membrane
  4. D.Having flagella for location
Deebii fi ibsa ilaalaa

Deebii: C Absence of nuclear membrane

Maaliif

Bacteria are prokaryotes. Their DNA lies free in the cytoplasm because there is no nuclear membrane around it. Among the choices, this is the feature that separates bacteria from eukaryotic cells.

The other options are shared with many organisms: every cell has a selectively permeable membrane, protozoa and some algae are also unicellular, and sperm cells and many protists also move with flagella.
