You would use the digestive system (which includes your mouth and teeth) to chew, swallow, and begin digesting the carrot. You would use the nervous system to taste and smell the carrot. You would use the muscular system to close and open your jaw to chew the carrot and also to raise the carrot to your mouth and to maintain posture. You would also use the muscular system to swallow and digest the food using peristalsis (which is the back and forth motion by smooth muscle to churn the carrot). You would use the skeletal system (specifically the maxillae (upper jaw and hard palate) and the mandible (lower jaw)) as support for your muscles to chew the carrot and the skeletal system to maintain posture while sitting at the table. These are the systems directly involved with ingesting a carrot.
Biotechnology can be defined as using living organisms and to develop new products that can help human beings. Biotechnology has had an impact as follows:
Medicine: In the field of medicine, Biotech has resulted in the discovery and mass production of 'small molecule pharmaceutical drug'. Other examples include Genetic testing and genetic diagnoses of diseases.
Agriculture: Biotech has led to the development of GMC (genetically modified crops) which was able to bring about Green revolution and increase world production of food approx. 10 times.
In animals, selective breeding and mutation breeding are examples of how Biotech has helped in factory farming methods.
Conservation: Biotechnology is being used to harness the potential of creating energy from plant-based sources such as Plankton and Algae. Biotech has also led to the development of trees and plants which are more resilient to climate change and can help in transforming communities.
Answer:
Oceanic crust is younger crust . Well, It is because, an oceanic crust is formed when a continental crust undergoes a big tension crack due to the forces generated inside the earth, which may be because of the magma dwelling inside. As the crack becomes prominent, the continent is broken into the segments with a big oceanic basin kind of structure between them (This takes millions and millions of years). Sediments deposit in the basin and get stratified to form the oceanic crust. This is the reason that oceanic crust is younger than the continental crust.
These two closely related species have evolved to use the resources of an ecosystem in a different way, in order to be able to cohabit and coexist. Niche is an ecological term used to refer to the ecological roles of species in an ecosystem. In the same context, niche differentiation refers to the process by which competing species use the environment differently in a way that helps them to coexist. In addition, interspecific competition is another ecological term used to describe how individuals of different species compete for the same resources in an ecosystem. When individuals of these two species of swallows live on the same ecosystem, they compete against the resources (food and habitat) that are available in this habitat. Due to niche differentiation, they are able to coexist in the same ecosystem by limiting their habitat.
The answer could be the fact that all species posses 23 universal proteins. These proteins vary slightly in some DNA sequences but are pretty much the same. These proteins are responsible for tasks such as DNA replication and translation from DNA to proteins. These activities are crucial to all forms of life. The presence of these universal proteins suggest that modern life evolved from a single common ancestor.
