options for A, B and C.
respiration,
photosynthesis,
transpiration.
The answers are;
1. Respiration.
2. Photosynthesis.
3. The processes form the carbon cycle.
Explanation:
From number 1. Prices which is respiration, respiration is a process of gas exchange which oxygen is inhaled and carbondioxide is exhaled into the atmosphere.
Photosynthesis uses the carbon to produce food. This is a process where carbondioxide are used by green plants in line with light energy from the sun and water to produce glucose and oxygen.
The processes are carbon cycle because carbon cycle shows how carbon flow from the atmosphere to the biosphere.
Some man-made fibres, too, are derived from naturally occurring polymers. For instance, rayon and acetate, two of the first man-made fibres ever to be produced, are made of the same cellulose polymers that make up cotton, hemp, flax, and the structural fibres of wood.

Answer:
Explanation:
Exons can be shuffled independently known as exon shuffling. It can be done in various ways, leading to infinite number of combinations to discover new and meaningful coding sequences hence various proteins. Due to exon shuffling, evolution need not occur only by the slow accumulation of point mutations but might also move ahead by “quantum leaps” with new proteins appearing in a single generation.
Genetic defect is the most likely cause for a miscarriage during the first three months of pregnancy. The most likely time for a miscarriage is during the first three months of pregnancy. It is the common type of pregnancy loss or spontaneous abortion, it is the natural death of an embryo or fetus before it is able to survive independently.
