ECOLOGY
The Conversion of nitrates to nitrogen gas. It is carried out by denitrifying bacteria in the soil.
What is Denitrification?
These are Very small organelles made of protein and RNA. Function is to make proteins
What are ribosomes?
This is the Name given to chromosomes when they are not dividing
What is chromatin?
The transfer of pollen from an anther to a stigma on a different plant of the same species.
What is cross-pollination?
These Control the direction of blood flow.
What are valves?
This Involves an active physical contest between 2 individuals. Eg – Robins actively defend a territory for feeding, nesting and reproduction.
What is Contest Competiotion?
These are Cells grown on a sterile nutrient medium outside an organism
What is a tissue culture?
A form of cell division that produces two daughter cells, genetically identical to each other and to the parent cell.
What is mitosis?
This is the Resting period when seeds undergo no growth and have reduced cell activity/metabolism
What is dormancy?
This chamber of the heart is where you'll find the pacemaker.
What is the right atrium?
A study to find out the type(s) of organism that exist in an ecosystem
What is a qualitative study?
This is The movement of a substance(usually ions) from its area of lower concentration to its area of higher concentration. (Opposite of diffusion)
What is active transport?
This is all the living parts of a cell.
What is protoplasm?
This is what all Female parts of the flower are called collectively
What are carpel?
These are Formed in the bone marrow and matured in the lymph nodes. They recognise proteins(antigens) on the cell membranes of invading organisms and respond by making antibodies which kill the invaders
What are Lymphocytes?
The Ways in which organisms are specialised either in structure/behavior to survive competition.
What are adaptations?
This Has a low concentration of solutes and thus a higher concentration of water than another solution.
What is a hypotonic solution?
Where certain cells lose their ability to control both the rate of mitosis and the number of times mitosis takes place
What is Cancer?
The Growth of plants in response to gravity.
What is geotropism?
Non granular and are also phagcytic. They often leave the capillaries in search of foreign material.
What are monocytes?
The functional role of an organism in an ecosystem. Eg – How it feeds, what it eats, who eats it etc.
What is a Niche?
This Is the pressure of the cytoplasm and vacuole against the cell wall
What is Turgor pressure?
This process is where large particles are engulfed by the cell and become incorporated into a vacuole within the cell.
What is Phagocytosis?
Asexual reproduction in plants. Eg – Strawberry
What is vegetative propagation?
A blood pathway that begins and ends in capillaries
What is a portal system?
