Core Concept Of Biology ( Lecture 3 )

Question 1

Core concepts of biology

Answer 1

1. Life is subject to chemical and physical laws
   2.structures determine functions
2. Living systems transform energy and matter
3. Living systems depend on on information transactions
4. Evolution explains the unity and diversity of life

Question 2

What is the complementary of structures and function

Answer 2

Structures often seem designed to perform specific functions because of their unique size, shape, form and location.

Structures determines what function can take place

Shape and organization provide clues to what specific structures do

Question 3

How can organisms transform energy

Answer 3

Photosynthetic organisms transform solar energy into chemical energy

Others transform chemical energy into other firms of energy

Question 4

What is evolution

Answer 4

The process by which species arises and change over time. The idea that all organisms have descended from common ancestors

Question 5

What is evolution

Answer 5

The process by which species arises and change over time. The idea that all organisms have descended from common ancestors

Question 6

Lines of evidence of supporting evolution

Answer 6

1. Fossil record
2. Age of the hearth
3. Mechanisms of heredity
4. Comparative anatomy
5. Molecular evidence

Question 7

What is fossil record

Answer 7

Fossils are preserved evidence of the past

Question 8

Explain the core biology concept that says that living things transform matter and energy

Answer 8

All living things consistently require energy. Some gain this energy through photosynthesis while others transform chemicals in various forms of energy.

Question 9

Explain that structures define functions

Answer 9

certain structures because of their shape, form, size and location seem to perform specific functions.
These structures determine what function can be.

Question 10

Define that life is subject to chemical and physical laws

Answer 10

Knowledge such as chemical bonds, kinetics, thermodynamics and molecule composition is relevant in biology.
