Two ethical issues of using Biotechnology are Affordability and Privacy. Two social issues of Biotechnology are Harm to the environment and Bio-terrorism.

<u>EXPLANATION: </u>

The most concerning ethical issue of using biotechnology is the cost and access to new treatments.
The drugs that break clots that cause heart attacks, for example, are extremely expensive and so the common people cannot afford them.
The second ethical issue is Privacy.
The technology can decode the human genome which might reveal the future health information of a person.
The first social issue of using biotechnology is the harm to the environment.
It is not sure how will the ecosystem react when a new organism is introduced in the ecosystem.
Another social issue is that terrorists might make new superbugs or infectious viruses, using biotechnology, which might not have any cure.

Type of radioactive decay which has occurred is an alpha decay.

Explanation:

Type of radioactive decays:

Alpha decay is defined as the decay process in which alpha particle is released. In this process, a heavier nuclei decays into a lighter nuclei. The alpha particle released carries a charge of +2 units and a mass of 4 units.

Beta decay is defined as the process in which beta particle is emitted. In this process, a neutron gets converted to a proton and an electron. The released beta particle is also known as electron.

Gamma decay In this process, an unstable nuclei releases excess energy by a spontaneous electromagnetic process and gamma -radiations are emitted. These radiations does not carry any charge and are electrically neutral.

In humans, curly hair is dominant over straight hair. Which cross below has the correct probabilities listed

adell [148]

Answer:

A.a woman heterozygous for hair curl, a man heterozygous for hair curl will produce 25% straight hair, 75% curly hair

Explanation:

a woman heterozygous for hair curl, a man heterozygous for hair curl will produce 25% straight hair, 75% curly hair

using C as the allele for hair curl:

Cc x Cc will produce the following genotypes: CC, Cc, Cc, cc

25% will be homozygous dominant (curly hair)
