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%.

The red blood cell liposomes are more hypertonic relative to water than the frog egg liposomes.
The red blood cell liposomes are more hypertonic relative to water than the frog egg liposomes.
True, because they contain more ion channels which provide higher concentrations of ions.
True, because the concentrations of Na and Ca ions in red blood cells liposomes are higher than those of the frog egg liposomes.
False, because the interior solution in both sets of liposomes is the same.
False, because the concentrations of Na and Cl ions in red blood cells liposomes are lower than those of the frog egg liposomes.
The hypertonicity of red blood cell liposomes and frog egg liposomes would depend on the respective concentrations of solutes, notably ions, within each. Carrying out measurements of these concentrations is crucial for a definitive comparison. Ion channels do not directly influence hypertonicity.
Explanation:Whether the red blood cell liposomes are more hypertonic relative to water than the frog egg liposomes depends on a few factors. To determine this, we would need to measure the concentrations of various ions in both types of liposomes.
In general, a solution is considered hypertonic if it has a higher concentration of solutes. Therefore, if the concentration of ions, particularly Na and Ca ions, in the red blood cell liposomes, is higher than the frog egg liposomes, then they would be more hypertonic. However, without specific concentrations, we cannot definitively say one is more hypertonic than the other.
It's also important to note that the presence of ion channels doesn't necessarily make a solution more hypertonic, as the hypertonicity is influenced by the concentration of solutes within the solution, not the pathways for solute movement.

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.

What organelle must temporarily break apart so that the dna can divide up?
The organelle that must temporarily break apart to allow DNA division (replication) to occur is the nuclear envelope. The nuclear envelope is a double membrane structure that surrounds the nucleus of eukaryotic cells.
The nuclear envelope is a double membrane structure that surrounds the nucleus of eukaryotic cells. It separates the cell's genetic material (DNA) from the cytoplasm, where most of the cell's activities take place. During DNA replication and cell division (such as mitosis and meiosis), the nuclear envelope needs to be disassembled to allow the DNA to be accessed and replicated. In preparation for cell division, the nuclear envelope disassembles to allow the DNA to be replicated and divided into daughter cells.

During prophase, the nuclear envelope dissociates into small vesicles and organelles like the Golgi complex and endoplasmic reticulum fragment and disperses toward the periphery of the cell. This process enables the division of DNA.
Explanation:During prophase, the nuclear envelope starts to dissociate into small vesicles, and the membranous organelles (such as the Golgi complex or Golgi apparatus, and endoplasmic reticulum), fragment and disperse toward the periphery of the cell. The nucleolus disappears (disperses). The centrosomes begin to move to opposite poles of the cell. Microtubules that will form the mitotic spindle extend between the centrosomes, pushing them farther apart as the microtubule fibers lengthen. The sister chromatids begin to coil more tightly with the aid of condensin proteins and become visible under a light microscope.

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.
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.

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.
