The disease is an autosomal recessive pattern. Which of the following statements is true?
The child will likely have Tay-Sachs disease if both parents pass on the recessive alleles.
The child will likely have Tay-Sachs disease if both parents pass on the dominant alleles.
The child will only have Tay-Sachs disease if the mother passes on the recessive allele.
The child will likely have Tay-Sachs disease if the father passes on the dominant allele.
Answer:
The answer is B: The child will likely have Tay-Sachs disease if both parents pass on the dominant alleles.

Before entering the Krebs cycle, an intermediate molecule bonds to a 2-carbon molecule. This intermediate complex enters into the Krebs cycle, and combines with a 4-carbon molecule to form citric acid. The name of this molecule is _____.
Answer:
The link reaction occurs after glycolysis and before the Krebs cycle. It begins with pyruvate, which loses a carbon as carbon dioxide is formed - leaving a 2-carbon molecule. The link reaction terminates with the production of acetyl coenzyme A.

If a female carrier wants to have children with a color-blind male, what is the probability of one of their sons could be color blind?
Answer:
The correct answer would be - 50% chances of color-blind sons.
Explanation:
Color blindness is a sex-linked genetic disorder that is found mostly in males. It is an X-linked recessive trait which means it will be masked in the presence of the normal X chromosome and in absence of the dominant allele caused this disorder.
Carrier women mean there is a heterozygous condition for this trait and she can pass it the next generation and color blind man means there is one recessive gene X chromosome and one Y chromosome:
Cros between XXc and XcY
gametes: X, Xc and Xc Y
X Xc
Xc XXc XcXc
Y XY XcY
Thus, here one out of two males is colorblind therefore, the probability would be 50%

Bacteria are all the same and do not have variations within the species.
False or True
Answer:
false
Explanation:
Bacteria are all the same and do not have variations within the species, which is a false statement as the bacteria can undergo asexual reproduction and can show variation within a species.
What is the significance of variation among bacterial species?Variation is common in bacterial species because it benefits them in many ways, such as it affects bacterial virulence, which may make some bacteria more lethal and affect animals and plants than others. The variation can cause the bacteria to become antibacterial-resistant and adapt to a new environment, allowing them to thrive and grow.
Hence, bacteria are all the same and do not have variations within the species, which is a false statement as the bacteria can undergo asexual reproduction and can show variation within a species.

Explanation:
The half-life of a radioactive element, such as carbon-14, is the time it takes for half of the atoms of the element to decay. How many half-life periods have passed if a fossil contains 1 32 of the original amount of carbon-14?
Answer:
This half-life represents the time in which the number of radioactive nuclei falls to 1/2 of its starting value. Activity, being proportional to the number of active nuclei, also has the same half-life. Life of all the radioactive elements is infinite. Radioactive decay constant 'λ', of different elements different.
