QUESTION 9
if a woman who is a carrier for Fragilex syndrome (an X-linked disorder) has children with a man who does not have the disorder, what chance do their
daughters have of being carriers of Fraglese
None
50%
25%
100%
Answer:
Daughters who are descendants of a woman carrier of Fragile X Syndrome and a healthy man will have a 50% chance of having or being carriers of the syndrome.
Explanation:
Fragile X syndrome has an autosomal dominant inheritance pattern, linked to the X chromosome. That is, someone with an altered X chromosome can either be a carrier or have the syndrome.
In this case, the mother is a carrier of the altered chromosome (X) while the father is neither a carrier nor has the condition (XY).
Cross X x XY
Alleles X Y
[tex]X^{f}[/tex] [tex]X^{f}[/tex]X [tex]X^{f}[/tex]Y
X XX XY
The couple has a 50% chance of having daughters, and of those daughters half (50%) have the chance of having an Xf chromosome, and being a carrier or suffering from the syndrome.

When glucose, a 6-carbon sugar, is broken down during glycolysis, what product forms?
Answer:
pyruvate
Explanation:
In glycolysis, the 6-carbon sugar, which is glucose, is broken down into two molecules of a 3-carbon molecule called pyruvate.
During glycolysis, glucose is broken down into ; Pyruvate molecules and energy
Glycolysis is a cytoplasmic process during which glucose is broken down into two 3 carbon compounds ( pyruvate ) and energy is generated from t glucose in the process.
The breakdown of glucose during glycolysis is as represented below
Glucose + 2 NAD⁺ + 2ADP + 2Pi ----> 2 Pyruvate + 2 NADH + 2 H⁺ + 2ATP + 2 H₂O
Hence we can conclude that During glycolysis glucose is broken down into ; Pyruvate and energy.

A nerve impulse is an electrical charge running across a neuron. Explain why the simulation supports this explanation.
Answer:
Sudden reversal of the electrical charge across the membrane of resting neuron
Answer:
Stimulation of a neuron causes a change in the charge inside the cell from negative to positive. This change is caused by ions, which are atoms with an electrical charge, moving across the cell. This change within the cell is consistent with the definition of an electric charge.

What is the use of reverse transcriptase?Reverse transcriptase enzyme has been generally used by the retrovirus for their genome replication. This enzyme has been discovered by the Howard tenim.
Reverse transcriptase enzyme generates the complementary DNA from the mRNA template by the process of reverse transcription. The presence of RNase H, RNA-dependent DNA polymerase and DNA-dependent DNA polymerase activity enable the enzyme to convert the mRNA into DNA.
The position of the mRNA is to carry protein facts from the DNA in a cell's nucleus to the cellular's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates every three-base codon into its corresponding amino acid in a growing protein chain.
Therefore, The mRNA sequence will best match the section of DNA shown below is C-U-A-G-G-A. Thus, option C is correct.

Suppose that you feel something brushing against your abdomen. The sensory information would be carried to the spinal cord over a ________ ramus. rami communicantes white ramus communicans posterior anterior gray ramus communicans
Answer:
The correct answer is - ventral ramus.
Explanation:
Ventral rami are the spinal nerves that bring the sensory information through the sensory fibers and motor fibers for the innervates the ventrolateral body surface, structures in the body wall, and the limbs, skin, such as abdomen and joints of limbs.
If someone feels the brushing sensation against his or her abdomen the sensory information must be carried by the ventral ramus.

What will happen to the pressure in the brain if water moves into it from the blood?
Answer:
A sudden increase in the pressure inside a person's skull is a medical emergency. Left untreated, an increase in the intracranial pressure (ICP) may lead to brain injury, seizure, coma, stroke, or death. With prompt treatment, it is possible for people with increased ICP to make a full recovery
Explanation:
A medical emergency occurs when a person's internal pressure suddenly increases. An increase in intracranial pressure (ICP) may cause brain damage, seizures, comas, strokes, or even death if left untreated.
What is brain?The brain is a sophisticated organ that manages every bodily function as well as thought, memory, emotion, touch, motor skills, vision, respiration, temperature, and hunger. The central nervous system, or CNS, is made up of the spinal cord that emerges from the brain.
There are two distinct parts of the central nervous system: gray matter and white matter. Gray matter in the brain refers to the thicker, outer layer, and white matter to the thinner, inner layer beneath.
It is possible for patients with elevated ICP to fully recover with prompt treatment.
Therefore, A medical emergency occurs when a person's internal pressure suddenly increases. An increase in intracranial pressure (ICP) may cause brain damage, seizures, comas, strokes, or even death if left untreated.

Conduct online research to learn more about competition between two species not mentioned in this lesson. Make sure to include information about their niches, common resources, and other competitors.
Answer:
In many forest ecosystems, squirrels and chipmunks compete for acorns and some other resources. However, they don’t have the exact same niches. Squirrels nest in trees, while chipmunks live underground. These species don’t compete with each other for mates either. Thus, squirrels are in interspecific competition with chipmunks.
All squirrels in a particular ecosystem share the same niche. The same is true of all chipmunks. So, both of these species are in intraspecific competition. Competing with an individual from the same species is harder than competing with members of other species. For example, squirrels compete with other squirrels for not only food (acorns), but also shelter and mates. However, they also compete with some other species, such as deer and acorn weevils, for acorns. Furthermore, they are both prey for many of the same predators, such as hawks, raccoons, foxes, and weasels.
