LESSON 2: UNIFYING THEMES IN THE STUDY OF LIFE

Question 1

is the discipline of science that deals with the study of life. This comprises number of disciplines such as biochemistry and ecology
As a wide-ranging and complex science, biologists designed the term “unifying themes”, which serve as the 10ases for the study of life.

Question 5

Living things work as a system, at the same time they cannot be separated from non-living things since they are both operating as a system.

Answer 5

Biological system

Question 6

Answer 8

An ecosystem

Question 9

is an organized group of interacting parts.

Answer 9

Answer 10

Cell

Question 11

Cell examples

Answer 11

sperm cell
egg cell
root hair cell
ciliated epithelial cell
white blood cell
red blood cell
muscle cell
nerve cell

Question 12

Ivf (ISI)

Answer 12

Intracytoplasmic
Sperm
Injection

Question 13

Living things cannot live alone, their survival depends on how they interact with the environment.
Organism have evolved to live and interact with other organisms. Ecology deals with the interactions of living organisms with one another and their environment.

Answer 13

3. INTERACTION WITH
   THE ENVIRONMENT

Question 14

Living organisms use a source of energy for their metabolic activities.

Answer 14

Energy and life

Question 15

Some living organisms capture the light energy and convert it into chemical energy in food

Answer 15

Autothrops

Question 16

Some living organisms use chemical energy stored in molecules obtained from food.

Answer 16

Heterotrophs

Question 17

Organisms ‘ structures fit with its functions.
Bats navigate and feed insect prey using echolocation. They produce sound waves at frequencies above human hearing, called ultrasound. The sound waves emitted by bats bounce off objects in their environment. Then, the sounds return to the bats’ ears, which are finely tuned to recognized their own unique

Answer 17

Form and function

Question 18

Bats use

Answer 18

Echolocation

Question 19

Traits of parents are being passed from one generationt to the next generation.

Answer 19

Reproduction and inheritance

Question 20

Asexual, sexual reproduction

Answer 20

Single parent, two parents

Question 21

Organisms must maintain homeostasis to survive in diverse environments.

Answer 21

Regulation

Question 22

is the maintenance of constant internal conditions. All living organisms must live in a stable environment.
Cell
of the body
are
surrounded by a small amount of fluid, and normal cell functions depend on the maintenance of cell fluid environment including temperature, volume, and chemical content.

Answer 22

Homeostasis

Question 23

-_____distributes heat throughout the body

-evaporation of water helps
regulate____

Answer 23

Blood, body temperature

Question 24

-regulates temperature & changes in osmotic pressure
-maintain water balance in the body
-regulates blood sugar level

Answer 24

Hypothalamus, kidneys, pancreas

Question 25

Living organisms survive depending on how one will adopt to its changing environment.

Answer 25

8. ADAPTATION

Question 26

The change in living things over time. (The genetic makeup of a population of a species changes).

It is the process by which different kinds of living organisms are thought to have
develope
and
diversified from
earlier
forms during the history of the earth.
It accounts for both the diversity and unity of life.

Answer 26

Evolution

Question 27

The field of science is changing the lives of all organisms through research.

Answer 27

BIOLOGY AND SOCIETY
