You are a genetic counselor. A couple comes to you for advice. The female is pregnant with their first child. Both have family histories with Tay-Sachs disease, which is a disorder that progressively destroys nerve cells, leading to loss of motor skills, vision, and hearing. 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.
Explanation:
Brainliest pls!!
Answer:
The child will likely have Tay-Sachs disease if both parents pass on the recessive alleles.
Explanation:
With autosomal recessive diseases, if the offspring recieves two recessive alleles, they will exhibit the trait.

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.

What are enzymes?The biological polymers that catalyze biochemical processes can be referred to as enzymes.Most enzymes are proteins having catalytic properties that are essential to carry out various operations.
One may compare the essential function of a single substrate enzyme to a lock and key.The substrate is the key in this scenario, while the enzyme is the lock. The enzymes here breaks the dipeptides resulting into the formation of mono-peptides. They are very specific and can only alter specific reactions by reacting to the substrates.Therefore, the correct option is 2.

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.

Why does the inner core of Earth remain solid even though it is very hot?
A
The Coriolis effect creates a centralized gravitational spin at Earth's core.
00
The pressure is so great at the inner core that it causes atoms to push together.
С
The inner core is not as hot as the outer core.
D
The inner core is made of the same material as the mantle.
Answer:
The pressure is so great at the inner core that it causes atoms to push together.
Explanation:
The inner core of Earth remains solid even though it is very hot because the pressure is so great at the inner core that it causes atoms to push together. This is present in the second option.
What are the different layers of the earth?The earth has three layers, such as the inner hot core, the mantle, and the last outer crust, and the temperature of each layer is varied and made up of different compositions. The outer crust has different minerals as the mountains, plants, and animals present there, while the molecules are not present under the high pressure here. The middle layer, known as the mantle, is composed of iron and other elements, whereas the inner core is hot and solid due to high pressure.
Hence, the inner core of Earth remains solid even though it is very hot because the pressure is so great at the inner core that it causes atoms to push together, so the second option is the correct answer.

Explanation:
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.
