Where is most of a healthy person’s fat stored?
Option a) under the skin and around organs. Most of a healthy person's fat is stored under the skin as subcutaneous fat and around organs as visceral fat. Excess visceral fat poses health risks, making fat distribution an important health consideration.
The correct answer to where most of a healthy person's fat is stored is a) under the skin and around organs. Fat is stored as subcutaneous fat just under the skin, as well as visceral fat that is found deeper in the body surrounding vital organs. This fat plays a crucial role in protecting organs and providing energy when needed. However, an excess of visceral fat, especially around the abdominal area, is associated with increased health risks, such as cardiovascular disease and type 2 diabetes. Recognizing the distinction between these types of fat storage is important for understanding one's health and the implications associated with varying fat distribution patterns.

A geneticist is studying two genes. each gene can be either dominant or recessive. a sample of 100 individuals is categorized as follows. gene 1 gene 2 dominant recessive dominant 56 24 recessive 14 6 (a) what is the probability that a random sampled individual, gene 1 is dominant (b) what is the probability that a random sampled individual, gene 2 is dominant (c) given that gene 1 is dominant, what is the probability that gene 2 is dominant
The probability of a random individual having dominant gene 1 is 56%, the probability of having dominant gene 2 is 70%, and the probability of gene 2 being dominant given that gene 1 is dominant is 89.2%.
Explanation:To find the probability that a random sampled individual has a dominant gene for gene 1, we need to divide the number of individuals with dominant gene 1 by the total number of individuals. In this case, there are 56 individuals with dominant gene 1 out of a total of 100 individuals, so the probability is 56/100, which simplifies to 0.56 or 56%.
Similarly, to find the probability that a random sampled individual has a dominant gene for gene 2, we divide the number of individuals with dominant gene 2 by the total number of individuals. In this case, there are 70 individuals with dominant gene 2 out of a total of 100 individuals, so the probability is 70/100, which simplifies to 0.7 or 70%.
To find the probability that gene 2 is dominant given that gene 1 is dominant, we consider only the individuals with dominant gene 1. Out of the 56 individuals with dominant gene 1, 50 individuals also have dominant gene 2. So the probability that gene 2 is dominant given that gene 1 is dominant is 50/56, which simplifies to 0.892 or 89.2%.

Glucose is mainly synthesized by plants and most algae during the photosynthesis process from water and carbon dioxide, using energy comes from sunlight.
Why is isopropanol miscible with cyclohexane?
Final answer:
Isopropanol is miscible with cyclohexane because it has a balance of polar and nonpolar characteristics, with its three carbon chain making it less polar, hence a better solvent for relatively nonpolar substances such as cyclohexanone. The 'like dissolves like' principle supports this miscibility.
Explanation:
Isopropanol is miscible with cyclohexane because it has a balance of polar and nonpolar characteristics which allows it to dissolve both polar and nonpolar substances. While isopropanol can form H-bonds with compounds like cyclohexanone due to its hydroxyl group, its three carbon chain imparts some nonpolarity, making it less polar compared to methanol. Hence, isopropanol is the better solvent for the relatively nonpolar cyclohexanone because like dissolves like; the nonpolar aspects of isopropanol are compatible with the nonpolar nature of cyclohexane.
The principle that 'like dissolves like' refers to the tendency for solvents to dissolve solutes that have similar intermolecular forces. Cyclohexane, being nonpolar, will better associate with isopropanol's nonpolar alkyl chain, resulting in strong solute-solvent interactions. This leads to a miscible mixture, as opposed to a mixture with a compound that has significantly different polarity, which might not be miscible.
On the other hand, compounds like ethanol and methanol have more extensive hydrogen bonding capacities due to their shorter alkyl chains and stronger polarity, which might not blend as well with the nonpolarity of cyclohexane, potentially leading to immiscibility.

what must obtain energy through their diets
Answer:
Heterotrophs
Explanation:
The organisms that can not make their own organic food obtain the energy and nutrition from the food they eat. These organisms that depend on plants or other organisms for their energy are called heterotrophs.
For example, the human can not carry out photosynthesis as plants do. So, human obtain their energy from the food derived from plant and/or animal sources they eat.
You are looking at very lightly stained cells under the microscope, and you want to increase the contrast so that you can see them "better." you ________ the iris diaphragm to ________ the light.
To enhance the contrast of lightly stained cells under a microscope, one needs to close the iris diaphragm to decrease the light. This change improves visibility by heightening the contrast but remember to find a balance because too much or too little light can obscure the details.
Explanation:When observing very lightly stained cells under a microscope and seeking to improve contrast, you should close the iris diaphragm to decrease the light.
The iris diaphragm is a part that manages the amount of light reaching the specimen. By reducing the light that comes through, you heighten the contrast, thus making the cells more visible. A key thing to remember when using the microscope is that both too much and too little light can wash out the details of the specimen, so finding the right balance is crucial.

Sugar dissolves readily in water because it is a(n) ____ substance
Answer:
The answer that fits the blank space is hydrophilic.
Explanation:
A hydrophilic substance is basically a substance with a very high polarity. If something has a high polarity, it's needed to know where is this polarity, because remember, a polar substance can have non polar and polar bonds, it depends on lots of factors. After stablishing that, we can check the hydrogen bonds, with that, we can confirm that this substance (sugar) will easily dissolve in water.

A species of rose (plants) lacks thorns. how would biologists explain how a species of rose lacking thorns evolved from an ancestral rose species with thorns?
A thornless rose species likely evolved due to natural selection where thornless variants had an advantage, leading to increased prevalence of this trait over time.
Biologists would explain the evolution of a species of rose without thorns as a process influenced by natural selection and genetic mutations. Thorns are mechanical defenses that protect roses from herbivores, but in some environments, thorns may not be necessary, or their costs may outweigh their benefits. A mutation might arise that results in a rose without thorns. If the environment favors thornless roses due to decreased pressure from herbivores or energy savings, these thornless roses would have a selective advantage.
Over generations, the frequency of the thornless trait would increase in the population, leading to a new species of thornless roses through the process of evolutionary adaptation.
List examples of biological macromolecules that rely on hydrogen bonding
Answer:
DNA, RNA and proteins.
Explanation:
Hydrogen bonds are the most intense type of intermolecular force that occurs between permanent dipoles of molecules, where the positive pole is always hydrogen, and the negative pole can be fluorine, oxygen or nitrogen, because these elements are very electronegative, that is, they attract the electrons of the double bond more strongly and have a negative partial charge.
Hydrogen bonds are very important to maintain the structure and function of many biomolecules, among which we can mention: DNA and RNA (hydrogen bonds unite the nitrogenous bases responsible for the formation of DNA and RNA strands), and proteins ( hydrogen bonds allow proteins to assume their three-dimensional structure.)
Advantage of multicellular organisms
Final answer:
Multicellular organisms have specialized cells that enhance survival through division of labor, forming tissues, organs, and organ systems. Sexual reproduction in these organisms promotes genetic diversity, which is advantageous for adaptation. The complex organization of multicellular organisms allows for refined control of biological processes.
Explanation:
One critical advantage of multicellular organisms is their ability to undergo specialization. In these organisms, different cells perform specific functions, optimizing efficiency and survival. Specialized cells in multicellular organisms come together to form tissues, which organize into organs, and further into organ systems, allowing for advanced functions that single cells cannot accomplish alone.
For example, in human beings, there are muscle cells, nerve cells, blood cells, and many others, each designed for particular tasks. These cells form tissues like muscle tissue or nerve tissue, which then combine to make organs such as the heart or brain. Organ systems like the circulatory system transport nutrients and oxygen to these organs, facilitating division of labor within the organism. This compartmentalization enhances not only survival but also complex behaviors and adaptations.
Another advantage is the potential for sexual reproduction, which promotes genetic diversity. Most multicellular organisms reproduce sexually, yielding offspring with unique genetic combinations, which can be beneficial for adapting to changing environments or resisting diseases.
Signal transduction is a process that takes longer in multicellular organisms due to the complexity of their bodily structures. Yet, this complexity allows for precise control and regulation of biological processes, underscoring the sophistication of multicellular life forms.

The innermost, soft core of the hair shaft is the
The cortex, a layer of compressed, keratinized cells, surrounds the medulla, the central core of the hair, and the cuticle, an exterior layer of extremely hard, keratinized cells. A longitudinal cross-section of the hair follicle shows these layers.
What is the hair shaft?The visible portion of the hair that protrudes from the skin is called the shaft.
The hair root is located in the skin and extends into the skin's deeper layers. The hair follicle, which is encased in a sheath of connective tissue and skin, surrounds it and is joined to a sebaceous gland.
The portion of the hair shaft that is not attached to the follicle is largely exposed at the skin's surface.
The remainder of the hair, which is rooted in the follicle, is referred to as the hair root and is located underneath the skin's surface.
Therefore, the medulla is the innermost, soft core of the hair shaft.

The rate at which a substance passes through a semipermeable membrane is determined
Final answer:
The rate at which a substance passes through a semipermeable membrane is influenced by molecule size, concentration gradients, and the substance's physical and chemical properties, illustrating the principles of hyper-, hypo-, and isotonic conditions.
Explanation:
The rate at which a substance passes through a semipermeable membrane is determined by several factors, related to the properties of the membrane and the substance itself. A semipermeable membrane is characterized by its selectivity, allowing certain molecules to pass through while blocking others. This selectivity is significantly influenced by the size of the molecules, the concentration gradient across the membrane, and the physical and chemical properties of the molecules in question.
The principles of hyper- (higher concentration), hypo- (lower concentration), and iso- (same concentration) are key to understanding how substances interact across a semipermeable membrane. The efficiency and direction of molecular movement across such membranes underscore the intricate balance necessary for cellular function and molecular transport in biological systems.
