Answer:
Mother - XAXA
Father - XY
Explanation:
Please see the attached image - complete question
Solution -
In the second cross the female is affected while the male is unaffected
The disease mentioned in the question is dominant X inked which means even one X chromosome can cause the disease. Thus, it will impacts males more than females.
Let the allele representing a diseased X gene be XA
and the allele for normal X gene be X
The offspring have all diseased males, which means that the genotype of affected female will be XAXA
And the genotype of unaffected male will be XY
The child having an equal chance of inheriting the dominant allele or the
recessive allele for freckles from her mother is what applies.
The law of segregation by Mendel states that diploid organisms have a pair
of alleles and are passed to their offspring at random.
The woman being heterozygous means she has the dominant and recessive
allele present. Due to the law of segregation stating the alleles are passed
at random to the offspring, the child will have an equal chance of inheriting
the dominant allele or the recessive allele for freckles .

Answer:
C
Explanation:
Volcanic activity spews greenhouse gases, such as carbon dioxide, into the atmosphere. These gases reduce albedo because they do not allow particular wavelengths of light to escape into space after hitting the earth’s surface. This is how they cause global warming that results in climate change.
Answer:
Conductivity
Explanation:
Conductivity is the property of a material which describes the ease with which that substance permits or conducts heat and electricity through it.
Materials can either be good, poor or non-conductors.
Good conductors are those materials which allow heat and electricity to pass through them easily. Such materials are useful in making electrical wires and heating vessels. Metals are good conductors of heat and electricity.
Some other materials are poor conductors of heat and electricity as they do not allow heat or electricity to pass through them easily. Examples are air and water.
Some other materials are non-conductors as they do not allow heat and electricity to pass through them. These materials are otherwise known as insulators. They are useful in making things such as pot handles, electrical wire insulators, etc. Examples of insulators are plastic, rubber, wood, etc.
Someone in a car during a thunderstorm is safer inside because the rubber tires do not allow for the heat and electricity of the lightning to pass through the vehicle as it is a non-conductor of heat and electricity.
D. is the correct answer. Hope this helps! :)
