Answer:
4)
Explanation:
Gametes have one haploid (n) genome, which is half of somatic cells, having one diploid (2n) genome combined through fertilization from two haploid (n) gametes.
In humans, gametes have 23 chromosomes, and somatic cells have 23 homologous pairs, which is 46 chromosomes.
Different species have different numbers, but most follow the same pattern.
Answer:
Explanation: Diffusion is a process that allows particles to move from areas of high concentration to areas of lower concentration. The process requires that particles are moving. As long as particles are not at a temperature of 0K (absolute zero) they have kinetic energy (energy of movement)
Monosaccharide molecule is produced and stored as energy for future use is Glucose.
Unlike people, plants must produce their own energy through photosynthesis in order to meet their needs for fuel. Plants produce and store starch in their leaves for short-term needs.
A polysaccharide, such as starch, is created when a series of glucose molecules are bonded together to form a longer molecule.
In starch, there are two varieties of polysaccharides:
- Amylose – a linear chain of glucose
- Amylopectin – a highly branched chain of glucose
Depending on the plant, starch is made up of between 20-25% amylose and 75-80% amylopectin.
