Answer:
Telomeres, the ends of chromosomes, shorten as we age, but this process can be slowed through exercise
Explanation:
The following that demonstrates how aging can be influenced by heredity is "Telomeres, the ends of chromosomes, shorten as we age, but this process can be slowed through exercise"
Telomeres are known to be pieces of junk DNA which are usually found at the end of end of chromosomes. The length of telomeres shorten with age.They become shorter and shorter and gets to a point when the cells cannot divide without losing some pieces of DNA. When it shortens, it affects lifespan and health of an individual.
According to the genetic theory of aging, it is seen that genes determine lifespan.
Studies has revealed that exercises helps to lengthen telomeres and also helps the heart and lungs to function well.
Answer:
The standard unit used to measure energy and work done in physics is the joule, which has the symbol J. In mechanics, 1 joule is the energy transferred when a force of 1 Newton is applied to an object and moves it through a distance of 1 meter. Another unit of energy you may have come across is the Calorie.
Explanation:
Human activities that contribute to desertification include the expansion and intensive use of agricultural lands, poor irrigation practices, deforestation, and overgrazing.
Answer:
d. the actual dimensions.
Explanation:
In Engineering, it is a standard and common practice to use drawings and models in the design and development of buildings, tools or systems that are being used for proffering solutions to specific problems in different fields such as banks, medicine, telecommunications and industries.
Hence, an architect or design engineer make use of drawings such as pictorial drawings, sketches, or architectural (technical) drawing to communicate ideas about a plan (design) to others, record and retain informations (ideas) so that they're not forgotten and analyze how different components of a plan (design) work together.
Architectural drawing is mainly implemented with computer-aided design (CAD) software and it's typically used in plans and blueprints that illustrates how to construct a building or an object.
Additionally, architectural drawings such as a section view in a general plan, show in detail how the areas of a building relate to each other, as well as accurately illustrating the actual (true) shape and size of a building in the design and development process.
In dimension drawings, the dimensions written on the drawing are the actual dimensions and the drawings are then made using a scale to reduce the drawing in same proportion.
