77
Q

what is the division of labor?

A

The different functions performed by different cells and tissues.

78
Q

define organ level with examples?

A

Organs are two or more types of tissues that work together to complete a specific task.
For example stomach is an organ specialized for the digestion of proteins and for storing food. Two major types of tissue
are present in its structure. Epithelial (glandular) tissue secretes gastric juice for the digestion of proteins.
Muscular tissue performs contractions of stomach walls for grinding of food and moving food to the posterior end. So two tissues perform their specific functions, which collectively become the function of the stomach.
Stomach heart liver brain lungs

79
Q

define organ system level with examples.

A

an organ system is a group of organs that perform related functions
Digestive system, urinary system circulatory system, respiratory system, Nervous System

80
Q

define organism level with examples

A

an organism has several organ systems that function together.
Different organs and organ systems are organized together to form an individual or organism.
In organism, the functions, processes and activities of various organs and organ systems are
coordinated. For example, when a man is engaged in continuous and hard exercise, not only his
muscles are working but also there is an increase in the rate of respiration and heart beat. This
accelerated rate of respiration and heart beat supplies more oxygen and food to the muscles which
they need for continuous work.
human

81
Q

how does a cell become dependent on its fellow cells?

A

As a cell or tissue becomes more specialized, it becomes increasingly dependent on its fellow cells.
Example: a muscle cell depends on blood cells for its need of oxygen

82
Q

what is a mustard plant?

A

Its botanical name of it is Brassica campestris. It can be divided into two parts on the basis of its functions. Vegetative parts consist of roots, stem leaves, and branches which do not take part in sexual reproduction. Reproductive parts consist of flowers, which directly take part in sexual reproduction, forming seeds and fruits.

83
Q

what is a frog?

A

The biological name of the frog is Rana tigrina. It is an amphibian. The body of the frog consists of limbs. trunk and head.

84
Q

eg of micromolecules

A

fans
fatty acids, amino acids, nucleotides and sugars

85
Q

eg of macromolecule

A

DLPS
DNA Proteins starch lipids

86
Q

Farming and Agriculture

A

Farming deals with the development and maintenance of different types of farms.
The agriculture profession deals with the food crops and animals which are the source of food. An agriculturist works for the betterment of crops like wheat, rice corn etc and animals like buffalo, cows etc from which we get food. In Pakistan, there are many universities that offer professional courses on agriculture after the higher secondary education in biology.
Careers associated with agriculture are food science, agricultural engineering & agricultural entomology etc

87
Q

Who was called Avicenna?

A

Bu ali sina was also called Avicenna in the west.

88
Q

bio elements join together through _______________?

A

ionic and covalent bonding

89
Q

explain the population level.

A

A population is defined as a group of organisms of
the same species located at the same place, at the same time. For example, the human population in
Pakistan in 2010 comprises 173.5 million individuals

90
Q

explain the community level.

A

A community is an assemblage of different populations, interacting with one another within
the same environment.Communities are collections of organisms, in which one
population may increase and others may decrease. A forest may be considered as a community. It includes different plants,
microorganisms, fungi, and animal species. Some communities are complex e.g. a forest
community, a pond community etc. Other communities may be simple e.g. a fallen log with various
populations under it. In a simple community number and size of populations is limited. So any
change in biotic or abiotic factors may have drastic and long lasting effects.

91
Q

explain the biosphere level

A

The part of the Earth inhabited by organisms’ communities is known as the biosphere. It constitutes all ecosystems (areas where living organisms interact with the nonliving components of the environment) and is also called the zone of life on Earth.
