Explanation:
Hi there!
The process of converting pH into [H+] is: pH = -log[H+]
pH + pOH = 14
The process of converting pOH into [OH-] is: pOH= -log[OH-]
you will definitely need a calculator for the conversions
Fossil hunters can be good stewards by respecting the area around the dig site. Instead of getting big machinery to do the dig and ruining the area around the fossil, they can instead be careful in obtaining the fossils.
By definition, a body system is primarily comprised of different organs and tissues that work one another to achieve a common body process. These body systems would include:
Circulatory system - concerns with the circulation of blood
Digestive system - breaking down of food particles
Skeletal system - composed of bone structures serving as our body's framework
Nervous system - composed of nerve cells that responds to different stimuli
Respiratory system - concerns of utilising the entry of oxygen and the exhalation of carbon dioxide.
Answer:
C. "Because you have had one child with Tay-Sachs, you must each carry the allele. Any child you have has a 25% chance of having the disease
Explanation:
Tay-Sachs disease is an autosomal recessive disorder that means a child will acquire the phenotype or we can say disease only when both the alleles which cause disease are present in the child.
Here, in this condition neither parent has Tay-Sachs but they gave birth to a child who is suffering from the disease then it simply means that both the parents are carrier of this disease i.e. they both are heterozygous.
The cross and probability of healthy and diseased child is shown as under:
Mother Father
Parents Tt Tt
/ | | \
Off-springs TT Tt Tt tt
<u>Out of these 4 probable off-springs only 3 with genotype TT, Tt & Tt will be healthy while the 1 with genotype tt will be diseased.</u><u> </u><u>So, the probability of diseased child is 1/4 which is 25%. </u>
Also, the birth of children is an independent event so if one child has already been born with this disease then it doesn't mean that the next 3 children will be healthy for sure i.e. birth of first child cannot influence the next child. In short we can also say that in the next birth, there is still 25% chance of the child being born with this disease because previous birth has nothing to do with next birth.
Classification is a method of grouping things together based on common qualities. Animal classification is critical since it aids in the identification and naming of all species on the planet. Animalia, Chordata, Mammalia, Primata, Hominidae sapiens are the classifications for humans.
