Eustachian Tube
Theeustachian tube(pharyngotympanictube) connects the middle ear cavity with the nasopharynx. It aerates the middle ear system and clears mucus from the middle ear into the nasopharynx. Opening and closing functions of theeustachian tubeare physiologically and pathologically important.
Green colour of plant is due to the presence of

_____ plants bears no fruits but process seeds
Cycas
____ are considered to be the simplest living organisms with ability to manufacture their own food by photosynthesis.
Blue-green algae
Bryophytes are
Non-Vascular plants
The forest in Pak comprising of _____ are facing the danger of extinction
Junipers

Photosynthesis is a bio-chemical process for the transfer of solar energy to
Petrological Cycle
Ginger is an example of
Rhizome
(Rhizome definition, a rootlike subterranean stem, commonly horizontal in position, that usually produces roots below and sends up shoots progressively from the upper surface.)
Earliest organisms that appeared on the surface of earth were probably
Throughout the Proterozoic era, from about 2.3 billion years ago until around 575 million years ago, life on Earth was mostly single-celled and small. Earth’s biota consisted of bacteria, archaea, and eukaryotic algae.
Osmosis?
A function of the spontaneous net movement of solvent molecules through a semi-permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides
____ plant micronutrients is involved in the electron transport in photosynthesis
Copper
Bamboo is a
Grass
Cork Cells are impervious to water because of the presence of
Suberin
Fern belongs to
Pterophyta
In____ section of the plant the function of photosyntesis takes place
Leaves
Photosynthesis takes place faster in
Red light
Age of tree can be determined by
Counting the number of rings in the stem
Protien which act as hormone is
Oxytocin
*(Protein hormones are a type of chemical compound in the body that regulate metabolism and cell function. They are derived from amino acids (the building blocks of proteins) and facilitate signaling between cells of the endocrine system and various other cells of the body.)
Potato is a modified form of
Stem
A plant cell is distinguished from an animal cell by the presence of
Cell Wall
A man with blood group A can receive blood from persons having blood groups
A and O
What does Mycology study?
Fungus
(study of fungi, including their genetic and biochemical properties, their taxonomy and their use to humans as a source for tinder, medicine, wine, cheese, food, and entheogens, as well as their dangers, such as poisoning or infection)
Duodenum is situated in
At the uppermost part of the small intestine
In brain, the site for intelligence, memory and emotion is present in
Cerebrum
Vaccines are
Treated bacteria or viruses or one of their proteins
Excessive vomitting and diarrhoea may result in the decrease of _____ in the blood stream
Sodium
Inuslin was discovered by
Canadian physician Frederick Banting and medical student Charles H. Best discovered the hormone insulin in pancreatic extracts of dogs. On July 30, 1921, they injected the hormone into a diabetic dog and found that it effectively lowered the dog’s blood glucose levels to normal
Haemophilia
Haemophilia, also spelled hemophilia, is a mostly inherited genetic disorder that impairs the body’s ability to make blood clots, a process needed to stop bleeding. This results in people bleeding longer after an injury, easy bruising, and an increased risk of bleeding inside joints or the brain.
____ is responsible for transferring the genetic information from one generation to the next
DNA
Anaerobics are
Bacteria which can complete their life cycle without oxygen
Deficiency of Iron in the human body causes
Anaemia
(Anaemia is a condition that develops when your blood does not contain enough healthy red blood cells or haemoglobin. These cells are important for carrying oxygen around the body)
The red colour of tomato is imparted by
Karotionoid
(Carotenoids, also called tetraterpenoids, are organic pigments that are produced by plants and algae, as well as several bacteria and fungi)
Proteins are made up of
Amino Acids
Pencillins (Penicillin is one of the most commonly prescribed antibiotics.) are made by Fungus called
Pencillium
Penicillium ascomycetous fungi are of major importance in the natural environment as well as food and drug production
Water helps in the metabolism process in the presence of
Enzymes
Enzymes are
Protien
Science of treatment of Muscular and skeletal system is known as
Orthopaedics
_____ area of the brain is responsible for control of the body temperature
Hypothelamus
EQUANIL
What is Equanil used for?
Meprobamate affects chemicals in your brain that may become unbalanced and cause anxiety. Meprobamate is used to relieve anxiety, nervousness, and tension associated with anxiety disorders. Meprobamate may also be used for purposes other than those listed in this medication guide.
Warm blood animals maintain high body temperature for faster
Breeding
Pituitary Gland controls
Growth of the bones
The yellow colour of the Urine is due to the presence of
Urochrome
Disease realted to lungs
Chronic obstructive pulmonary disease (COPD): Lung conditions defined by an inability to exhale normally, which causes difficulty breathing. Chronic bronchitis: A form of COPD characterized by a chronic productive cough. Emphysema: Lung damage allows air to be trapped in the lungs in this form of COPD
During formation of bread, the product that raises the bread is
Yeast
Ageing in human beings is caused by disapperance of _____ gland.
Thymus Gland
Antigen is a substance which
Destroys harmful bacteria
If a colour-blind lady marries a normal male, and gives birth to a son and a daughter, the
The son would be colour-blind but the daughter would be heterozygous normal
The Harmone are the
Chemical Messengers (a regulatory substance produced in an organism and transported in tissue fluids such as blood or sap to stimulate specific cells or tissues into action.)
Master gland is ____ gland which control the activities of
- Pituitary Gland
- Control the activities of Adrenal Gland, Adrenal and thyroid glands, Pancreas and Gonads glands.
