Wound healing is usually prolong in the elderly people due to three basic factors, these are:
1. delayed inflammatory response: inflammatory response allows the white blood cells and nutrient to reach the site of the wound in order to stimulate healing. This response is very slow in the elderly people.
2. reduced skin elasticity: skin elasticity has been highly reduced in elderly people.
3. Diabetes mellitus: most elderly people have diabetes mellitus; the condition prevent wound from healing.
Out of these three, the most important one is the delayed inflammatory response.
to understand what the result of these crosses would be like, we need to know what is gene
<h3>Gene</h3><h3 />
The gene is a strand of a DNA molecule (deoxyribonucleic acid), which carries the characteristics that are genetically inherited. They are composed of a sequence of DNA and RNA (ribonucleic acid), responsible for the production and synthesis of proteins in the cell. The gene's greatest attribution, therefore, is to be a store and transmitter of information.
Genes can be classified into:
- Dominant genes: assume the specific characteristic in the offspring;
- Recessive genes: manifests itself in the absence of the dominant gene;
- Structural genes: are those that contain the information that will determine the structure of living beings;
- Operator gene: acts on the functioning of other genes;
- Regulatory gene: responsible for controlling the synthesis and transcription of other genes.
<h3 /><h3 />
in genetics, are individuals who have pairs of genes that are identical or different alleles. This means that while the has two identical genes alleles, with the beings the opposite happens, since they have two different genes alleles.
with this information we can say that a white and short plant, when crossed with a plant for both traits, has 60% of this plant being with expression of the dominant genes and 40% of being with expression of the recessive gene.

Answer:
During platelet plug formation, platelets begin to stick to: collagen with the assistance of von Willebrand factor. As a platelet plug forms at an injury site platelets become activated and their cytoplasm: degranulates as they release chemicals such as ADP and thromboxane A2.
