Answer:
A)11,460 years
Explanation:half of a radioactive element represent the time take for half of it's components to dissociate or disintegrate.
For carbonn14 that undergo an emmision to form a stable carbon 14,it moves thus
14C(1 part) ______14C(0.5 parts)_____14C(0.25parts)
i.e it undergo two radioactive decay which means two half lives .
Since each half life is 5780 years ,the age will be 2×half lives= 2×5780=11,460 years
The answer is "c. Some alleles are dominant and other are recessive"
The environmental effects of an individual or group in terms of resources used and waste produced is an individual or group's ecological footprint (option A).
<h3>What is ecological footprint?</h3>
Ecological footprint is the measure of how much biologically productive land and water area an individual, population or activity requires to produce all the resources it consumes and to absorb the waste it generates using prevailing technology and resource management practices.
Living organisms make use of resources in the environment and these can either leave negative or positive effect on the environment that will affect sustainability.
Therefore, it can be said that the environmental effects of an individual or group in terms of resources used and waste produced is an individual or group's ecological footprint.

Answer:
<u>Polygenic therapies are more likely to show </u><u>unintended effects</u><u> in other regions of the genome likely resulting in harmful diseases.</u>
<u />
Explanation:
Gene therapy involves biotechnological techniques that add or remove gene sequences in the genome. These are typically used in eliminating harmful genes that cause genetic diseases or disorders and are generally thought to improve an individual's quality of life.
Polygenic traits are controlled by several genes. Similarly, polygenic diseases may be caused by variations in several gene sequences. These include hypertension, heart disease, and diabetes. Polygenic therapies are more likely to show unintended effects in other regions of the genome, leading to other deleterious disease-causing effects.
