Ten think-time questions on the seven characteristics of living things, species, the binomial name, kingdoms, vertebrates and arthropods, and dichotomous keys.
Transcript
Ten quick questions on the characteristics of living things and classification. Listen, think, then check your answer.
Question one. What is respiration? A, breathing air in and out. B, chemical reactions in cells that release energy from food. Or C, taking in food.
The answer is B, chemical reactions in cells that release energy from food. Respiration is a chemical reaction in cells. It releases energy from food.
Question two. Which characteristic is the ability to detect changes and respond to them? A, sensitivity. B, excretion. Or C, growth.
The answer is A, sensitivity. Sensitivity is detecting changes and responding. A plant that turns towards light shows sensitivity.
Question three. Removing the waste made by chemical reactions is called: A, nutrition. B, excretion. Or C, reproduction.
The answer is B, excretion. Excretion removes waste from the body. Carbon dioxide is an example.
Question four. A species is a group of organisms that can: A, live in the same place. B, reproduce to make fertile offspring. Or C, eat the same food.
The answer is B, reproduce to make fertile offspring. Members of a species can reproduce. Their offspring are fertile.
Question five. Which is the correct way to write the binomial name of humans? A, Homo sapiens. B, homo Sapiens. Or C, Sapiens homo.
The answer is A, Homo sapiens. The genus comes first, with a capital letter. The species comes second, with a small letter.
Question six. Which is the largest group in classification? A, species. B, genus. Or C, kingdom.
The answer is C, kingdom. The kingdom is the largest group. The species is the smallest.
Question seven. Which kingdom has organisms with chloroplasts that make their own food? A, animals. B, plants. Or C, fungi.
The answer is B, plants. Plants have chloroplasts. They make food by photosynthesis.
Question eight. Which of these animals is a vertebrate? A, an insect. B, a bird. Or C, a spider.
The answer is B, a bird. A bird has a backbone. Insects and spiders are arthropods, with no backbone.
Question nine. Which feature do all arthropods have? A, jointed legs. B, feathers. Or C, fur.
The answer is A, jointed legs. Arthropods have jointed legs. They also have a hard outer skeleton.
Question ten. A dichotomous key is a set of: A, questions that each have two answers. B, pictures with no words. Or C, Latin names in a list.
The answer is A, questions that each have two answers. Each question has two answers. The answers lead to the name of the organism.
