Fibrous roots grow from the main stem of the plant and does not have a primary root like the taproot. They grow downward and outward, with repeating branches to form a mass of small roots.Dicots and monocots are the two classes of flowering plants. The majority of taproot systems are composed of dicots and conifers.
Inflammatory response can be defined is a reaction of the body to injury or destruction of tissues. This reaction serves to dilute, destroy or simply wall off the agent causing the injury and is localized around the area of injury.Inflammatory response takes place in the following steps:1. Tissue damage caused by injury or bacterial infection is detected.2. Vasodilators and chemotactic factors such as histamine are released.3. As a result, there is increased capillary permeability and blood flow to the area.4. There is migration of phagocytes to the site of infection.5. Phagocytes and specific serum proteins attack and destroy bacteria.<span>6. Inflammation dies down once intruder has been destroyed.</span>
Answer:
anaphase, think a=apart and the chromosomes are being pulled apart
Answer:
D variations in individuals are not heritable
Explanation:
Genetic variation in individuals is what drives evolution. In a population of individuals in an environment, with the adequate resources, overpopulation can occur. However, resources are usually a limiting factor for population growth: there is not sufficient food/shelter etc. for everyone to survive.
Some individuals are better suited to success in the environment. This is because of random variation in their DNA that has arisen that give them a selective advantage. This allows them to thrive, take advantage of the limited resources over other members of the population, and be more likely to survive to reproductive age. This is natural selection.
Because this variation is genetic (in the DNA), they can then pass it on to their offspring. Over time, this leads to evolution over time.
