Answer:
Explanation:
The probability that the daughter of a mom with a dominant disease-causing allele on the X chromosome and a dad with the disorder will be affected with the disorder is 100%. This is because the daughter will inherit one X chromosome from the mom, which carries the dominant allele that causes the disorder, and one X chromosome from the dad, which is affected by the disorder.
Since the parents are unaffected, we can infer that they are both heterozygous carriers of the Lesch-Nyhan syndrome allele. If they have a son with the syndrome, we know that the son inherited the recessive allele from both parents. The chance that a daughter of this couple will inherit Lesch-Nyhan syndrome is 25%. This is because the daughter will inherit one X chromosome from the father, which does not carry the recessive allele, and one X chromosome from the mother, which has a 50% chance of carrying the recessive allele.
Since the condition is X-linked dominant, the man will pass on the dominant allele to all of his daughters. Therefore, the chance that he will pass it on to his daughters is 100%.
The function of mitochondria and chloroplasts is related to energy.I’m what way does their function differ
The "powerhouses" of the cell, mitochondria are responsible for cellular respiration and the breakdown and oxidation of fuel molecules. Plants and algae both have chloroplasts.
What performs the mitochondria's primary function?The traditional function of the mitochondria is called oxidative phosphorylation, which produces ATP by using the energy released through the oxidation of the food we eat. The majority of biochemical and physiological functions, including growth, mobility, and equilibrium, all require ATP as their main energy source.
What happens when mitochondria don't work?Producing energy is the mitochondria's primary job. In particular, high energy-demanding organs like the heart, muscles, & brain require more mitochondria to produce more energy. when the cell's mitochondria are not functioning properly or in sufficient numbers.

Answer: oligopoly
Explanation:
The term that describes a small group of firms that control a particular market for goods, therefore reducing competition is "oligopoly". An oligopoly occurs when a small number of firms dominate a market and are able to influence prices and other market factors. In an oligopoly, there are typically high barriers to entry, which can make it difficult for new firms to compete with the established firms. Examples of oligopolies include the market for soft drinks, where a few large companies dominate the industry, and the market for commercial aircraft, where only a few companies produce the majority of airplanes.

Answer:
Explanation:
Detoxifying enzymes and membrane components are produced and stored in the "smooth" endoplasmic reticulum (ER).
The smooth ER is a type of endoplasmic reticulum that lacks ribosomes, which are the structures responsible for protein synthesis. Instead, the smooth ER is involved in a variety of cellular functions, including lipid synthesis, carbohydrate metabolism, and detoxification of drugs and other toxins.
Detoxifying enzymes are produced in the smooth ER and are responsible for breaking down harmful substances and making them less toxic or more easily excreted by the body. The smooth ER is also involved in the synthesis of membrane lipids and the regulation of calcium ion concentrations in the cytoplasm.

A dichotomous key is a helpful identification and classification tool. Scientist also use genetics (DNA) to classify organisms? Now that we know a little more about dichotomous keys, which is a more accurate way to classify organisms? Explain.
Both dichotomous keys and genetics (DNA) can be used as tools to classify organisms, but the accuracy of classification depends on the context in which they are used.
What is a more accurate way to classify organismsDichotomous keys are useful for identifying and classifying organisms based on observable physical characteristics, such as their shape, color, size, and other morphological features. These keys work by providing a series of paired statements that help the user narrow down the possible identification of an organism until a final identification is reached. Dichotomous keys are particularly useful for identifying and classifying organisms that are difficult to differentiate based on external characteristics.
On the other hand, genetics (DNA) is a more accurate way to classify organisms at the molecular level. DNA analysis allows scientists to compare the genetic information of different organisms and identify similarities and differences in their DNA sequences. By comparing the DNA sequences of different organisms, scientists can determine their evolutionary relationships and classify them into different groups. DNA analysis is particularly useful for identifying and classifying organisms that are difficult to differentiate based on external characteristics or for organisms that have evolved to look similar to each other.
In summary, both dichotomous keys and genetics (DNA) are useful tools for classifying organisms, but DNA analysis is generally considered to be a more accurate way to classify organisms as it provides a more detailed and precise understanding of their evolutionary relationships.

Define resting membrane potential
The electrical potential difference across the plasma membrane of a cell during its non-excited condition is referred to as the resting membrane potential of the cell. The value of the electrical potential difference inside a cell compared to the extracellular environment is traditionally used to describe the electrical potential difference across a cell membrane.

dave has discovered a new lipid-soluble hormone. which of the following is true regarding this hormone?
Without more information about the specific hormone that Dave discovered, it is impossible to determine the statements is true.
What are hormones?Hormones are chemical messengers produced by specialized cells or glands in the body that are secreted into the bloodstream and transported to various organs and tissues. Hormones play a critical role in regulating a wide range of physiological processes, including growth and development, metabolism, reproduction, mood, and behavior.
Hormones can be classified into two main categories based on their chemical structure and solubility: water-soluble hormones and lipid-soluble hormones. Water-soluble hormones, such as insulin and adrenaline, are made up of proteins and peptides and are able to dissolve in the bloodstream. Lipid-soluble hormones, such as testosterone and estrogen, are made up of lipids and are able to pass through the cell membrane.
Hormones interact with specific receptors on target cells, triggering a cascade of signaling pathways that lead to various cellular responses. The level of hormone production and release is tightly regulated by a complex feedback system involving multiple organs and glands in the body, ensuring that physiological processes are kept in balance.

Using this information, ribosomes select the appropriate transfer RNA (tRNA) molecules that carry the correct amino acids and combine them in a specific order to form protein chains.
