Answer:
F2: 1/4 phenotype Ad (genotype Ad/Ad), 1/2 phenotype AD (genotype Ad/aD): 1/4 phenotype aD (genotype aD/aD)
Explanation:
In this case, A and D loci are strongly linked and there is little or no recombination between them. Therefore, Ad/Ad and aD/aD individuals will produce only one type of gametes (i.e., individuals Ad/Ad only can produce Ad gametes, while aD/aD individuals only can produce aD gametes), thereby all F1 will be Ad/ aD. Finally, Ad/aD individuals can produce two types of gametes: Ad and aD, thereby the F2 will be 1/4 Ad/Ad (phenotype Ad), 1/2 Ad/aD (phenotype AD) and 1/4 aD/aD (phenotype aD)
Parental cross: Ad/Ad x aD/aD
F1 generation: Ad/aD
F2 generation:
Ad aD
Ad Ad/Ad Ad/aD
aD Ad/aD aD/aD
F2 generation: 1/4 Ad/Ad (phenotype Ad), 1/2 Ad/aD (phenotype AD) and 1/4 aD/aD (phenotype aD)

Humans benefit from natural resources every day. For example, right now you're using a computer or similar device
to read this question. Can you name any natural resources that were likely used to build this device? What natural
resources are you using by operating it?
Answer:
copper
Explanation:
is a mineral used to make electrical conductors because of its durability.
human beings are also natural resources,so by me operating this computer,am utilizing myself as a natural resource.
The laptop is a device which is generally used. It is composed of electrical conductors which contains metals such as copper. Copper is a natural resource.
What are Natural resources?Natural resources are those resources which are drawn from the nature and are used with few modifications. This includes the sources of valued characteristics such as those for commercial and industrial use, aesthetic value, scientific interest, and cultural value.
Copper is a highly recyclable, non-renewable natural resource. It is present in a finite amount and cannot be regenerated once used fully. Copper is a soft and malleable metal which is used in the electrical wires and cables for its good conductivity, in the industrial machinery and construction materials for its durability, machinability, and corrosion resistance, and also the ability to be cast with high precision.

Describe two ways in which the above law protects citizens against human trafficking
Answer:
The law in question is not included so I will include tow different laws and how they protect people from human trafficking.
1. The Victims of Trafficking and Violence Prevention Act (TVPA).
This Act made human trafficking a Federal crime while also establishing rules on how to prosecute human traffickers and getting the victims of trafficking reintegrated into society and protected. Under this Act therefore, citizens are protected because the law would act as a deterrent to a lot of would-be traffickers.
2. The Mann Act of 1910.
Under this Act, it is a crime to make promises to people such that they cross state lines and are then involved in activities they did not sign up for - this is a definition of human trafficking so this law protects citizens from that.
