A human disease example in which a dominant allele that is lethal in homozygous state is Huntington’s. A person that is heterozygous for Huntington’s disease and a normal individual had four children together. What is your expected outcome for the surviving children (ratio-wise for the genotype)? What is the percentage of the children that are expected to survive? Draw a punnett square to support your answer.
Answers
The expected outcome for the surviving children of a heterozygous Huntington's disease parent and a normal parent is 50% chance of being carriers of the disease and 50% chance of not carrying the disease, with a 50% expected survival rate.
Huntington's disease is an autosomal dominant disorder caused by a mutation in the HTT gene. If an individual inherits one copy of the mutated gene, they will develop the disease, regardless of whether the other allele is normal or mutated.
In this scenario, the heterozygous parent has one normal allele and one mutated allele. When crossed with a normal individual, the Punnett square shows a 50% chance of passing on the mutated allele to each child.
Therefore, two of the four children are expected to be carriers of the disease, and the other two are expected to not carry the disease. Additionally, because the disease is lethal in homozygous individuals, the expected survival rate for the children is 50%.

As you finish your college degree, you learn that the mountain behind your childhood home in the hills of the town you grew up are slated to be mined for coal using the mountain top removal method. Your parents, who still leave there are worried for their health and safety and do not want to lose the beautiful forested creek and ravine behind their property. However your brother is out of work and could use the mining job. What would you attempt in this situation?
Answers
In this situation, I would try not to allow the exploitation of the mountain to occur, degrading nature and the property that her family has, because her brother may look for another job, but nature would not recover.
What are the impacts of coal mining?The burning of coal for energy produces highly toxic effluents, such as mercury and other heavy metals such as vanadium, cadmium, arsenic and lead. In addition, the release of carbon dioxide causes pollution in the atmosphere, exacerbating global warming and contributing to acid rain.
With this information, we can conclude that Sedimentation and pollution of rivers due to improper disposal of unused material would make life on the family's property unfeasible.

Explain how to distinguish different species by their DNA.
Answers
DNA analysis can be used to distinguish different species by comparing specific regions of their DNA sequences.
To distinguish different species by their DNA, scientists primarily focus on comparing specific regions of the DNA sequences that are highly variable among species. One commonly used region is the mitochondrial DNA (mtDNA), which is inherited maternally and has a higher mutation rate compared to nuclear DNA. Another region is the ribosomal RNA genes (rRNA), which exhibit variations among species.
The process typically involves extracting DNA samples from different organisms, isolating the target region of interest, and sequencing the DNA to determine the nucleotide sequence. The sequences obtained from different species are then compared to identify differences and similarities.
These differences can be used to create DNA profiles or genetic markers specific to each species. Advanced techniques such as DNA barcoding or whole-genome sequencing can provide more comprehensive information and aid in species identification.
By comparing DNA sequences, scientists can uncover genetic variations unique to different species, allowing them to distinguish and classify organisms accurately. This information is valuable in various fields, including taxonomy, conservation biology, forensic science, and evolutionary research.

The body loses water and salt in sweat.Explain why drinking large volumes of pain water after exercising may affect the salt balance in the body.
Answers
Answer:
The combined effect of water retention (thanks to ADH) and increased water consumption leads to an increase in blood volume and subsequent restoration of fluid balance in the body. By increasing blood volume, ADH also plays a role in reducing plasma osmolality and therefore sodium concentration.
Explanation:
Anti-diuretic hormone(ADH) helps to control blood pressure by acting on the kidneys and the blood vessels.
Its most important role is to conserve the fluid volume of your body by reducing the amount of water passed out in the urine.
the loss of the lumbricids' trochophore larval stage is an obvious adaptation to a more terrestrial environment group of answer choices true false
Answers
The loss of the lumbricids' trochophore larval stage is a true adaptation to a more terrestrial environment because the larvae require a marine environment to survive. The absence of a trochophore stage means that the lumbricid is better adapted to the terrestrial environment and can reproduce more easily in it.
Lumbricids are earthworms that belong to the phylum Annelida. They are generally found in soils in a variety of habitats, such as forests, grasslands, and agricultural land. Lumbricids have a segmented body that is long and narrow, with a reddish-brown color. They have no legs, and instead, they move by contracting and relaxing their muscles to push themselves through the soil.The trochophore larval stage is an early stage in the development of many invertebrate animals. It is characterized by a ciliated band that encircles the animal's body, allowing it to swim freely in the water. The trochophore larval stage is seen in many marine invertebrates, such as molluscs and annelids. It is also found in some freshwater invertebrates, such as certain species of snails and clams.The loss of the lumbricids' trochophore larval stage is an adaptation to a more terrestrial environment. This adaptation enables the lumbricids to live in soils instead of water. Since the trochophore larval stage is adapted to a free-swimming lifestyle in water, it is no longer necessary for lumbricids living on land. Instead, lumbricids have evolved a direct mode of development, in which they hatch from eggs and develop directly into miniature versions of adults.Learn more about trochophore larval stage: https://brainly.com/question/26971426

what term applies to the point at which the membrane returns to resting potential after having been depolarized?
Answers
The term that applies to the point at which the membrane returns to resting potential after having been depolarized is called "repolarization".
To understand this process, it is first important to know what is meant by membrane potential. Membrane potential is the difference in electric charge between the inside and outside of a cell. In neurons, for example, the resting membrane potential is around -70 millivolts (mV), meaning that the inside of the cell is negatively charged compared to the outside. This resting potential is maintained by the action of ion channels that selectively allow certain ions to pass through the cell membrane, creating an electrical gradient.
When a neuron receives a stimulus, it can become depolarized, meaning that the membrane potential becomes less negative or even positive. This happens when positively charged ions, such as sodium (Na+) and calcium (Ca2+), enter the cell. This depolarization can trigger an action potential, which is an all-or-nothing response that allows the neuron to transmit information to other neurons or cells.
However, the depolarization must be followed by a process called repolarization in order for the neuron to be able to fire again. During repolarization, the ion channels allow potassium (K+) ions to leave the cell and restore the negative resting potential. This is a crucial step in neural communication, as it allows the neuron to reset and prepare for the next stimulus.
In summary, repolarization is the process by which the membrane potential of a cell returns to its resting state after having been depolarized. This process involves the movement of potassium ions out of the cell, restoring the negative resting potential and allowing the neuron to fire again.

Answer:
To produce many copies of DNA
Explanation:
Polymerase chain reaction (PCR) is a method widely used to rapidly make millions to billions of copies (complete copies or partial copies) of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it (or a part of it) to a large enough amount to study in detail. PCR was invented in 1983 by the American biochemist Kary Mullis at Cetus Corporation. It is fundamental to many of the procedures used in genetic testing and research, including analysis of ancient samples of DNA and identification of infectious agents. Using PCR, copies of very small amounts of DNA sequences are exponentially amplified in a series of cycles of temperature changes.
