Answer:
One is polar and the other is non-polar.
Explanation:
The makeup of both water and isopropanol is different from each other due to their polar nature. Water is a polar substance means that it makes poles i.e. positive or negative while on the other hand, isopropanol is non-polar substance so due to this reason water and isopropanol make different layers. If both are polar or nonpolar substances so they will able to mix with each other.

sulfonamides inhibit bacterial folic acid synthesize enzyme( Dihydropteroate) which is responsible the activation (PABA) for synthesis of folic acid
How are meiosis and mitosis similar?
Answer:
both processes of cell division in which cells reproduce
they share similar steps (prophase, metaphase, anaphase, telephase, cytokinesis) (meiosis has a second division but still follows the same steps)
Answer:
Meiosis II is very similar to mitosis; chromatids are separated into separate nuclei. As in mitosis, it is spindle fibers that “pull” the chromosomes and chromatids apart. The end result of meiosis is four cells, each with one complete set of chromosomes instead of two sets of chromosomes.

observe the given relation and fill in the blanks cucumber: tendril citrus: meiosis: reduction division mitosis:
Answer:
citrus: thorns
mitosis: equational division
Explanation:
From the relationship:
Tendrils are thread-like appendages found in most climbing plants. They primarily function as supporting organs for climbing plants (such as cucumber) by stretching out and twinning around physical supports. The equivalence of this in citrus is the thorn.
Meiosis is a reductional cell division in which the chromosome number of the daughter cells is half of that of the other cells. Mitosis is equational division because the chromosome number of the parent cell is the same as that of daughter cells.
White blood cells (WBCs) are more resistant to lysis than red blood cells (RBCs). When looking at a sample of blood for WBCs, what could you do to reduce interference from RBCs? Group of answer choices Mix the blood in a hypotonic solution, which will cause the RBCs to lyse. Mix the blood in a hypertonic solution, which will cause the RBCs to lyse. Mix the blood in a salty solution to cause the RBCs to lyse. Mix the blood in an isotonic solution and allow the WBCs to float to the top.
Answer:
The correct option is this: MIX THE BLOOD IN A HYPOTONIC SOLUTION WHICH WILL CAUSE THE RED BLOOD CELL TO LYSE.
In order to reduce interference from red blood cell, mix the blood sample with a hypotonic solution. Because the red blood cells has more solute concentration, water from the hypotonic solution will enter into its cells and with time the cells will burst since they do not have much resistance against lysis. The bursting of the cells will eliminate the red blood cells and leave you with white blood cell to work with.

on which surfaces was there more friction? how did you reduce the friction on objects?
Answer: Rougher surfaces have more friction between them than smoother surfaces. That's why we put sand on icy sidewalks and roads. You can't slide as far across ice with shoes as you can on the blades of skates (see Figure below). The rougher surface of the soles of the shoes causes more friction and slows you down.
Explanation:
Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force.

Explanation:
while obtaining the vitals during the seconary assessment, the EMT will assess the respirations. what woul dbe included about the respirations during the primary vitals assessment
Answer:
Rate and tidal volume
Explanation:
Tidal volume is the volume of air moved in or out of the lungs with each normal breath. A normal tidal volume is around 500 to 600 mL per inspiration and/or 6 to 7 mL per kilogram of body mass. An Emergency Medical Technician (EMT) should assess the respiratory rate (as well as rhythm and quality), having into account that a normal respiratory rate in an adult is 12 to 18 breaths per minute (BPM). Moreover, an appropriate tidal volume is also fundamental in assisting individuals in respiratory distress and arrest.

Consider a neuron in which the Cl- concentration inside of the cell is 15 mM and outside of the cell is 140 mM. Once the ions flow and reach an equilibrium, approximately what will be the concentration of Cl- inside of the cell
Answer:
The correct answer is - negative.
Explanation:
Cl- ion is more concentrated outside of the cell, as it is given 140 and therefore it will try to move to the inside of the given cell as inside ion concentration is low.
At last, the diffusive force will be get to equilibrium due to an electrostatic force pulling Cl- ions back out of the cell. At this equilibrium point, Cl- ions will moved towards to the the neuron and cause the membrane potential to be more negative.
What is the purpose of using a Punnett square in studying genetics?
A. to determine the probability of an offspring to breed with another of the same phenotype
B. to determine the exact number of offspring having a particular genotype
C. to determine the probability of an offspring having a particular phenotype
D.to determine the probability of an offspring having a particular genotype
The purpose of using a Punnett square in studying genetics is to determine the probability of an offspring having a particular genotype. Thus, the correct option for this question is D.
What is Punnett square?Punnett square may be defined as a type of table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are determined. It is named after Reginald C. Punnett, who proposed this approach in 1905.
In genetics, Punnett square is extremely utilized in order to predict the possible outcomes of two unknown genotypes. With the help of these genotypes, phenotypes of a specific set of alleles are also determined. The important concept of Punnett square is that it always determines the probability, not the exact number.
Therefore, to determine the probability of an offspring having a particular genotype is the purpose of using a Punnett square in studying genetics. Thus, the correct option for this question is D.

The condition of muscle fatigue is best explained by: Question 1 options: insufficient intracellular quantities of ATP due to excessive consumption the inability to generate sufficient quantities of ATP due to feedback regulation of synthesis the all or none law lack of intracellular calcium
Answer:
The correct answer is ''insufficient intracellular quantities of ATP due to excessive consumption''
Explanation:
The energy source for the muscle to contract efficiently is adenosine triphosphate (ATP). When ATP is metabolized, energy is obtained. Under normal conditions, the muscle has a sufficient energy reserve to support a limited time of maximum activity. When this reserve is depleted, the body activates other metabolic pathways to achieve more ATP. Glucose is activated first, then carbohydrates, and last - only if the exercise is prolonged - lipids (fats). The muscle, therefore, ends up transforming this ATP into the necessary energy.Whether our body uses more fat or more glucose / glycogen as fuel will depend, above all, on the intensity and duration of physical exercise. The body uses more fat the more gentle and prolonged the exercise; while, the more intense the sport, the more important the need for glycogen will be.Muscle fatigue is the inability or lack of strength to continue doing a certain activity. It happens when the muscles are not strong enough to continue. Specifically, when carrying out a physical activity, the active muscle requires oxygen and energy reserves of glycogen; When the intensity of the activity is increased, this need for oxygen increases, exceeding the levels that the transport system is capable of providing.This situation leads to the active muscle looking for another source of energy, increasing lactic acid which, in turn, it develops a metabolic acidosis that can lead to the breakdown of muscle fiber. ATP is obtained from the oxidative degradation of metabolic substrates such as muscle glycogen, serum glucose, free fatty acids originating from muscles or adipose tissue, being characteristic of muscle fiber, the consumption of ATP, and the production of ADP and Pi, much faster than it regenerates.
