The energy used by sperm to move up the fallopian tube is stored in the epididymis <span>of the sperm's midpiece. </span>The epididymis<span> is a tube located at the back of the </span>testicles. During ejaculation, the sperm move from the lower part <span>of the </span>epididymis. They<span> have not been activated by products from the prostate gland yet, and they are not able </span>to swim. However, they are transported through the peristaltic action of muscle layers within the vas deferens. They are mixed with the diluting fluids of the seminal vesicles and other accessory glands before ejaculation.

Answer:
The phenotype may change constantly throughout the life of an individual because of environmental changes and the physiological and morphological changes associated with aging. Three types of natural selection, showing the effects of each on the distribution of phenotypes within a population.
Answer:
Photosynthetic process
Explanation:
Cellulose, a tough, fibrous and water-insoluble polysaccharide in the cell walls of plants. It is the most abundant organic macromolecule on Earth and also the main component of a plants structure, conferring rigidity on the plants' cells.
Cellulose chains are arranged in microfibrils or bundles of polysaccharides arranged in fibrils which in turn make up the plant cell wall.
All plants are made up of polysaccharides, a very large sugar molecule made of hundreds or thousands of single sugar units (monosaccharide). Cellulose is composed of a long chain of at least 500 glucose molecules joined together by B-1,4- linkages.
Green plants create this simple sugar molecules (glucose) on their own through the process of photosynthesis. Photosynthesis is the chemical combination or fixation of C02 and water by the utilization of energy from the absorption of visible light. This glucose produced is a building carbohydrate that combines with other sugars to form the plant structure (as they make up part of cellulose) and store energy.
Chromosome is apart of a cell that contains genetic material inform of genes, it contains DNA molecules packaged around histone proteins. Mitosis is a type of cell division that take place in the somatic cells where a cell divides into two daughter cells with the same number of chromosomes as the parent cell (diploid). Therefore, in this case each daughter cells will have 30 chromosomes.
