The vascular bundles contain xylem vessels, which transport water, and phloem vessels, which transport glucose. A food chain shows how food passes through a community of organisms. The thyroid gland secretes thyroxine to control the metabolic rate.
Progesterone production carries on and menstruation does not occur. A cell is removed from the embryo for genetic screening.
The eye is a sense organ for detecting light. The genetic code is universal in all living organisms, so a gene from one organism can be placed into another where it will continue to carry out its function.
They are opened and closed by the guard cells. The ileum is long and has a very large surface area. Nutrition Enzymes are biological catalysts and control nearly all reactions in the body.
The Respiratory System Breathing ventilation is a set of muscular movements that draw air in and out of the lungs. When we feel cold, shivering increases the rate of respiration and more energy is released as heat.
Parasites feed off a living organism called the host. This gives the plant support. Section 2 requires only 30 minutes and asks 27 multiple-choice questions that require the candidate to apply scientific knowledge from Key Stage 4 of the National Curriculum for England in school mathematics and science.
T lymphocyte A type of lymphocyte that differentiates in the thymus that is responsible for cell-mediated immunity. It is caused by a selective closing and opening of voltage-sensitive ion channels. Deforestation leads to loss of habitat, and increased soil erosion.Nope!
We used Biology for IGCSE by Gareth Williams (Publisher Nelson Thornes), and Physics for You (which i think was a GCSE book). Biology for IGCSE was a great textbook, the physics one wasn’t – it was a bit messy and didn’t really adhere to the curriculum (I mean, afterall it wasn’t written specifically for IGCSE).
Gravitation. Gravitational field strength at a point is defined as the gravitational force per unit mass at that point. Newton's law of gravitation: The (mutual) gravitational force F between two point masses M and m separated by a distance r is given by. Heat Transfer and explaining physical changes and physical properties using a particle model.
