This can be solved with Punnett squares. The affected male has the
genotype, and the female is homozygous recessive. This means that she does not carry this, and therefore, will have the genotype XᵇXᵇ
While doing this Punnett Square, keep in mind that in order to have the male offspring affected, their genotype
has to be
Since there are no
, the probability of their male offspring inheriting this disease is 0%
Answer: Possible life in non earthlike environments.
Explanation: As per the information provided in the question, the microbe located in California's Lake Mono has a variation in the shape of its DNA as they use arsenic ( if phosphorous was once no longer available) to comprise in the nucleotides of their DNA.
This shows the possibility of life structure in the non-earth-like environment because existence types that originated on earth like environment possess carbon, nitrogen, oxygen, and phosphorous ( that is composed of four fundamental elements).
But existence can additionally be shaped in an environment that lacks phosphorous ( for instance, DNA shaped in microbes utilized arsenic in absence of phosphorous, indicating version in their structure).
Answer:
protected; increase
Explanation:
Ozone is composed of trioxygen which is highly reactive gas compared to dioxygen. Ozone layer is present in stratosphere and troposphere and protect the humans from ultraviolet radiations but it may be toxic if inhaled. Ozone can be broken down into molecular oxygen by chlorine and bromine atoms.
A hole was discovered in ozone layer in 1982 and scientist believed that it could be dangerous for human health. The compounds involved in depletion of ozone are mainly Chlorofluorocarbons (CFS) and (HFCS). Then a global agreement was signed in 1987 which leads to prohibition of use of all chemicals that are involved in depletion of ozone layer. The problem of ozone depletion is solved by the agreement and ozone hole started to recover it from 2000.
But recent reports showed that the alternative chemicals used to protect the depletion of ozone layer began to trap the heat inside the earth like greenhouse effect. Now scientists are in search of chemical that can prevent both ozone depletion as well as global warming.
Peer review is a means of quality control for scholarly journal articles and books. It is the evaluation process of academic, scientific and professional work done by other individuals working in a similar field. Sometimes, the articles published in academic Journals are also referred as scholarly journals.
Hope this helps.
