19.) Coral polyp and a leaf both are:
a) Cells
b) Tissue
c) Organisms
d) Organs
20.) Which of the following system increase most of heat during workout?
a) Lymphatic system
b) Immune system
c) Muscular system
d) Digestive system
Answers:
1.)
Solution: c) Chemical
Elements that are essential for mainlining life are basically smallest chemical. Hence, it is the most first level of organization.
2.)
Solution: b) Carbohydrates
Carbohydrates cellulose is used to build the cell wall in the plants. So, carbohydrate is essential in building the cell wall
3.)
Solution: b) Asymmetrical
Because it is not dividing the body into two equal halves means there is no symmetry present in the body hence asymmetrical.
4.)
Solution:a) Fats → Never forms Adipose tissue.
Fats are also known as lipids that form adipose tissue. It also provides energy. Fats never adipose tissue is wrong pair.
5.)
Solution: a) Ectoderm and endoderm.
Ectoderm and endoderm are the two external and internal layers present only and Third layer mesoderm is absent so because of only two layers the organism is diploblastic.
6.)
Solution:d) Cell
Each cell in the body has different structure and function. Cell is also known as basic structural and functional unit life. Specialized structures are present in the cell which is known as organelles.
7.)
Solution: c) Cellular level
Cellular level is present in sponges so their different cells are specialized to perform different task and functions.
8.)
Solution: b) Tissue
Organ is made up of different tissues that performs specific function. Two or more different tissues can form organ.
9.)
Solution: a) Heart
Liver, brain, Heart, stomach and lungs are the examples of organ which forms organ system.
10.)
Solution: a) Integumentary
Body temperature is mainly regulated by Integumentary system. It also produces vitamin.
11.)
Solution: d) A-iii), B-ii) and C-i)
Skeletal system includes all the bones and joints that supports body. It also stores minerals. Nervous system includes spinal cord, nerves, brain and sense organs. Endocrine system usually produces hormone by the glands.
12.)
Solution: c) Circulatory
Circulatory system excretes waste of carbon dioxide from cell. Circulatory system circulated blood in the body. So, it includes blood vessels, heart and blood.
13.)
Solution: b) With the help of hormone, it regulates body activities.
Endocrine system involves various glands that produce hormone. These hormone regulates the body activities.
14.)
Solution: b) Food
Digestive system mainly absorbs food. Also, it helps in the breakdown of food to get absorbed.
15.)
Solution: a) Blood
Urinary system also regulates volume of the blood and fluids. Regulation of composition of waste and blood occurs by the urinary system.
16.)
Solution: d) Carbon dioxide
In the respiration process, oxygen is supplied to the body and carbon dioxide is eliminated through nose.
17.)
Solution: d) One living organism
When an organism is maintained by functioning of all the body parts, then it is an organismic level of organisation.
18.)
Solution: c) Organ
The blue Man-o-war do include tissue but it does not include organs.
19.)
Solution: d) Organs
Different tissue together form an organ. For example, heart is an organ in the human body, a leaf is an organ in the plant.
20.)
Solution: c) Muscular system
During workout, body needs a lot of energy. The muscular system generates heat as by product. Heat in the body is generated because of more energy production.
