 Blue green ALGAE

Heterocysts, specialised for nitrogen FIXATION, occur in CERTAIN Blue green algae.

 Preservattives

There are many chemical preservatives USED in FOOD industry. SODIUM benzoate is generally used is KETCHUPS, pickles, jams etc.

 Saprophytic

Saprophytic BACTERIA get their FOOD from DEAD organic MATTER.

 Haemophilia

Haemophilia is a HEREDITARY DISEASE.

 KIDNEY

Filtration of BLOOD TAKES PLACE in kidney.

 Plague and Malaria

Vehicle-borne TRANSMISSION is a vehicle that is, an inanimate object or MATERIAL CALLED in scientific terms a "fomite"—becomes contaminated with the INFECTIOUS agent. The agent, such as a virus, may or may not have multiplied or developed in or on the vehicle. The vehicle contacts the person's BODY. Plague and Malaria are vehicle borne transmitted diseases.

 Bacteria

Bacteria play a central ROLE in the MAKING of DAIRY products such as BUTTER, cheese, yogurt ETC.

 BUFFALO

Theilreia PARVA CAUSES INFECTION in buffalo.

 Are nutrient-poor ENVIRONMENTS

Compared to LAND, the OPEN OCEANS are nutrient-poor environments.

 Stomata

The exchange of OXYGEN and carbon dioxide in the leaf (as well as the loss of water vapour in transpiration) occurs through pores called stomata (SINGULAR = stoma). NORMALLY stomata open when the light strikes the leaf in the MORNING and close during the night.

 BACTERIA

Among the many substances manufactured commercially by means of bacteria are ACETIC ACID, acetone, butanol, lactic acid and several vitamins.

 Acoelomates

If the BODY CAVITY is absent CALLED as acoelom and animal called as ACOELOMATE e.g., Platyhelminthes.

 SEPTUM

A WALL of muscle called the septum separates the LEFT and right atria and the left and right VENTRICLES.

 Tracheophytes

Tracheophytes have VASCULAR TISSUES i.e .XYLEM and PHLOEM VESSEL.

 PITUITARY

Growth HORMONE (GH) is an ANCESTRAL hormone SECRETED episodically from somatotroph CELLS in the anterior pituitary.

 Climate change

The Kyoto Protocol is an INTERNATIONAL agreement that aimed to manage and REDUCE carbon dioxide EMISSIONS and GREENHOUSE gases. The Protocol was adopted at a conference in Kyoto, Japan, in 1997 and became international law on February 16, 2005.

 Adipose

A adipose tissue is formed BENEATH the SKIN and between INTERNAL ORGANS.

 Contains fluoride to HARDEN the TOOTH ENAMEL

Contains fluoride to harden the tooth enamel is not a function of SALIVA.

 Histology

Histology, also known as microscopic ANATOMY or microanatomy, is the branch of biology which studies the microscopic anatomy of biological tissues. Histology is the microscopic counterpart to gross anatomy, which looks at LARGER structures VISIBLE WITHOUT a microscope.

 MALPIGHIAN TUBULE

Glomerulus and BOWMAN's CAPSULE CONSTITUTE Malpighian tubule.

 NUCLEUS, Cell membrane, Mitochondria, CYTOPLASM

Nucleus, Cell membrane, Mitochondria and Cytoplasm is present in ANIMAL cells.

 SPIRILLA

The BACTERIA which are twisted, HELICAL or spiral in shape and CALLED spirilla.

 A is TRUE R is FALSE

Assertion is true but the REASON is false.

 DNA replicates before the division

Meiosis 2 is similar to mitosis because it SEPARATES the chromosomes to have SISTER chromatids in each cell. In both processes, you are separating the chromosome and dividing the cell to make 2 cells out of 1.

 Cones

NORMAL cones and pigment sensitivity enable an INDIVIDUAL to distinguish all the DIFFERENT colours as well as SUBTLE MIXTURES of hues. This type of normal colour vision is known as trichromacy and relies upon the mutual interaction from the overlapping sensitivity ranges of all three types of photoreceptor cone.

 MITOCHONDRIA

Work on mitochondria did not stop in the 1950s after it was named “the POWERHOUSE of the cell.”

 Human body

ENZYMES are produced naturally in the body. For EXAMPLE, enzymes are REQUIRED for PROPER digestive system function. Digestive enzymes are mostly produced in the pancreas, stomach, and SMALL intestine.

 root hairs

Root hair cells are specialized epidermal cells that greatly increase the surface area of ROOTS. The function of root hairs is to COLLECT water and mineral NUTRIENTS present in the soil and TAKE this solution up through the roots to the rest of the plant.

 23

A human CELL has 23 pairs of chromosomes.

 PANCREAS

Trypsinogen is the PRECURSOR form (or ZYMOGEN) of trypsin, a digestive enzyme. It is PRODUCED by the pancreas and found in pancreatic JUICE, along with amylase, lipase, and chymotrypsinogen.

 Binary Fission

Bacteria reproduce by binary fission. In this process the bacterium, which is a SINGLE cell, divides into TWO identical daughter CELLS. Binary fission begins when the DNA of the bacterium divides into two (REPLICATES).

 Potassium metabisulphite

Chemicals like potassium metabisulphite may be ADDED to different foods or FRUITS to prevent or retard the GROWTH MICROORGANISMS.

 Iris

The SIZE of the pupil is controlled by the activities of two muscles: the circumferential sphincter muscle found in the MARGIN of the iris, innervated by the PARASYMPATHETIC nervous system: and the iris DILATOR muscle, running radially from the iris ROOT to the peripheral border of the sphincter.

 Seed plants

The vascular plants, or tracheophytes, are plants that have SPECIALIZED tissues for CONDUCTING water, minerals, and photosynthetic PRODUCTS through the plant. They include the ferns, clubmosses, horsetails, flowering plants, conifers and other GYMNOSPERMS. They are often called the higher plants or the seed plants.

 Algae and Fungi

A lichen is a COMPOSITE ORGANISM that emerges from algae or CYANOBACTERIA living among the FILAMENTS (hyphae) of the fungi in a mutually beneficial SYMBIOTIC relationship. The fungi benefit from the carbohydrates produced by the algae or cyanobacteria via photosynthesis.

 Histology

Histology is the branch of biology CONCERNED with the COMPOSITION and structure of plant and animal TISSUES in relation to their SPECIALIZED functions.

 Low HUMIDITY and high TEMPERATURE

The suitable CONDITIONS in which the RATE of EVAPORATION occurs more fastly are low humidity and high temperature.

 ARTERY

We GET PULSE RATE from artery.

 TRANSPIRATION

The ultimate cause of water MOVEMENT in a plant STEM against GRAVITY is transpiration.

 BLUE-green ALGAE

The bio-fertilizers used for rice CROP are Azospirillum, PHOSPHOBACTERIA, Blue green algae azolla and Mycorhiza.

 Production of ATP from the breakdown of glucose

Aerobic RESPIRATION is the aerobic CATABOLISM of nutrients to carbon dioxide, WATER, and energy, and INVOLVES an electron transport system in which molecular oxygen is the final electron acceptor.

 THYROID

Thyroid glands are LOCATED in the NECK, in close approximation to the first part of the trachea. In humans, the thyroid gland has a "butterfly" shape, with two LATERAL lobes that are CONNECTED by a narrow section called the isthmus.

 ALKALINE

Blood is alkaline.

 METAPHASE

The SHAPE of CHROMOSOME is CLEARLY VISIBLE at metaphase.

 PANCREAS

The most IMPORTANT hormone that the pancreas produces is INSULIN. Insulin is released by the 'beta cells' in the ISLETS of Langerhans in RESPONSE to food.

 Breaking down FOOD

They are necessary to the lives of people, plants, animals, and all other organisms. NUTRIENTS help break down food to give organisms energy. They are USED in every process of an organism's body. Some of the processes are GROWTH (building cells), repair (HEALING a wound), and maintaining life (breathing).

 VITAMIN A

Night BLINDNESS is CAUSED by LACK of vitamin A.

 CRANIATA

Vertebrate, ALSO called Craniata, any animal of the subphylum VERTEBRATA, the predominant subphylum of the phylum CHORDATA.

Ecology term was coined by Ernst Heckel. It STUDIES the INTERACTION of LIVING BEINGS with their environment.
