Answer:
The answer is "Option a".
Explanation:
In this question it is correct because, in a densely forested environment, the conformation of cords into an open country could be a disadvantage, and wrong choice can be defined as follows:
- The adjustments to a cup did not provide an observation coat, its ability to find tiny moisture condenses as well as the chemical defensive performance from many other predatory animals.
- Its plains are not accessible and America's bush deserts had also assisted them spread throughout almost all these same continents.
- Its satisfaction of its demands of local conditions does not prove which organisms expand their context to many other types of circumstances.
The appropriate response is an opponent-process theory. Opponent-process theory is a mental and neurological model that records for an extensive variety of practices, including shading vision. This model was first proposed in 1878 by Ewald Hering, a German physiologist.
To fully understand the processes occurring in present-day living cells, we need to consider how they arose in evolution. The most fundamental of all such problems is the expression of hereditary information, which today requires extraordinarily complex machinery and proceeds from DNA to protein through an RNA intermediate. How did this machinery arise? One view is that an RNA world existed on Earth before modern cells arose (Figure 6-91). According to this hypothesis, RNA stored both genetic information and catalyzed the chemical reactions in primitive cells. Only later in evolutionary time did DNA take over as the genetic material and proteins become the major catalyst and structural component of cells. If this idea is correct, then the transition out of the RNA world was never complete; as we have seen in this chapter, RNA still catalyzes several fundamental reactions in modern-day cells, which can be viewed as molecular fossils of an earlier world.
Answer:
The addition of new bone tissue is termed as bone remodeling. In the process of bone remodeling, the tissues of the bone are withdrawn or resorbed from the skeleton and the formation of new bone tissue takes place also known as ossification. The mentioned procedures also monitor the shape of the bones after the incidents like fractures.
In the process of bone remodeling, two types of cells play an essential part, that is, osteoblast that generates new bone and osteoclasts that dissociates a bone. In the process of bone remodeling, the resorption of the bone takes place by osteoclasts, which is succeeded by bone deposition by osteoblasts. In combination, the cells, which are accountable for bone remodeling are called BMU or basic metacellular unit.
