Natasha_Volkova [10]2 years ago
7 0

The most effective way to prevent DNA mutation from UV radiation is: (C.) Avoid UV radiation by wearing sunscreen.

Mutation is the change in the normal sequence of DNA. The agents that induce these mutations are called mutagens. The mutations can be harmful as they can hamper the normal functioning of the living body. Some mutations however do not cause any significant changes and they are therefore called silent mutations.

Sunscreen is a a cream or liquid applied to the skin that prevents the harmful radiations of the sun to enter the body. They protect from the sun's UV-A and UV-B radiations.

AlekseyPX

Answer:

c.Alejandro’s nurturing parents. Alejandro’s genotype includes exceptional musical ability, but it’s his parents’ support of this ability that encouraged those genes to be expressed.

Explanation:

this is an examole of the influence of environment on gene expression

His nurturing parent's  support  aided his skill developments for professionalism. Generally parents have great influence on the children social skill developments through thorough supervision and monitoring of their general activities.

In addition, they are  the  social vessels for their child's social interactions, and therefore determiners of  the experience to pass though in their immediate environments.   Conclusively parents  influences determine a child future.

In Alejandro case, the profession of both parents, the monitoring of his activities with musical instruments, and his regular practice(for   the development of neural pathways) showed influence of environment on the expression of  genotype, which aided his professionalism.

If he was not  born to family of guitarist,with no access  to a guitar he may not be a professional despite his musical genotype. thus interaction between gene and parental nurturing (environments)  favoured this.

Which indicators are living and non-living?
bulgar [2K]
Living indicators are species that are sensitive to changes in the environment. For example air pollution can be monitored by looking at lichen, which are sensitive to sulphur dioxide in the air. The number of lichen at a particular location indicates how clear the air is. Similarly, mayfly larvae are good indicators for water pollution because they're sensitive to the concentration of dissolved oxygen in water.

Non-living indicators are things like satellites which can measure the temperature of the sea surface, weather stations that measure atmospheric temperature, rain gauges to measure rainfall, and dissolved oxygen meters to measure concentration of dissolved oxygen in water.

3. In elastic deformation, the deformed body returns to its original shape and size after the stresses are gone. In ductile deformation, there is a permanent change in the shape and size but no fracturing occurs. In brittle deformation, the body fractures after the strength is above the limit. 

4. Normal faults are faults where the hanging wall moves in a downward force based on the footwall; they are formed from tensional stresses and the stretching of the crust. Reverse faults are the opposite and the hanging wall moves in an upward force based on the footwall; they are formed by compressional stresses and the contraction of the crust.  Thrust faults are low-angle reverse faults where the hanging wall moves in an upward force based on the footwall; they are formed in the same way as reverse faults. Last, Strike-slip faults are faults where the movement is parallel to the crust of the fault; they are caused by an immense shear stress.
