the lysis of red blood cells in blood agar is indicative of the presence of which enzymes?

Answers

Answer 1

 cause of hemolysis is the action of hemolysins, toxins that are produced by certain pathogenic bacteria or fungi. Another cause is intense physical exercise. Hemolysins damage the red blood cell's cytoplasmic membrane, causing lysis and eventually cell death.

Explanation: One cause of hemolysis is the action of hemolysins, toxins that are produced by certain pathogenic bacteria or fungi. Another cause is intense physical exercise. Hemolysins damage the red blood cell's cytoplasmic membrane, causing lysis and eventually cell death.

Answer 2

BAP assesses an organism's ability to produce hemolysins, enzymes that damage/lyse red blood cells (erythrocytes). The degree of hemolysis caused by these hemolysins aids in the identification of members of the genera Staphylococcus, Streptococcus, and Enterococcus.

What hemolytic pattern does S aureus shows on BAP?

On blood agar plates, colonies of Staphylococcus aureus are often encircled by zones of clear beta-hemolysis. The golden appearance of colonies of some strains is the etymological root of the bacteria's name; aureus meaning "golden" in Latin.

The action of hemolysins, toxins produced by certain pathogenic bacteria or fungi, causes hemolysis. Intense physical activity is another cause. Hemolysins cause lysis and eventually cell death by damaging the cytoplasmic membrane of red blood cells.

The action of hemolysins, toxins produced by certain pathogenic bacteria or fungi, is one cause of hemolysis. Intense physical activity is another cause.

Thus, Hemolysins cause lysis and eventually cell death by damaging the cytoplasmic membrane of red blood cells.

Which theory best describes this?

Answers

Answer:

Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two (replicates).  Bacteria do not grow and multiply the same way as animals or humans. They take in nutrients and reproduce by dividing – one bacteria splits and becomes two bacteria, two become four, four become eight and so on.

Mendel's dihybrid cross proves that the inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.

What is a dihybrid cross?

When two different traits are crossed together then it is called a dihybrid cross. These two different traits are regulated by two different genes.

In Mendel's dihybrid cross, he did cross between round yellow and wrinkled grees. There are two traits, color, and shape. In the F1 generation, all seeds were round yellow but they were heterozygous. Round shape and yellow color are dominant traits.

Then he self-pollinated F2 generation and found four types of seeds that were round yellow, round green, wrinkled yellow, and wrinkled green in the 9:3:3:1 ratio. The cross is attached in the image below.

Inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.

Earth's core is the source of the energy that drives the movement of tectonic plates. Which two processes help transfer this energy outward to earth's crust?

Answers

Answer:The two processes are CONDUCTION and CONVECTION

Explanation:

The Energy produced in the Earth core is generated by  Sun, gravitational force , radioactive decay, and the  Earth' rotation, To maintain balance in the earth, The  processes of CONDUCTION and CONVECTION transfer energy (HEAT) to Earth's interior, which also helps the movement of  tectonic plates at a  constant rate.

Now, inside the earth mantle is made up of hot solid rock and because Conduction occurs more in solids, Its currents helps the continuous  transfer of heat energy  from the warmer mantle at  the bottom   to  the cooler  mantle  at the top While Convection currents in the core move thermal energy causing  the rising and sinking of warm and cooler molten rock inside Earth, thereby maintaining the motion of tectonic plates and  creating a balance in the earth.

What is food energy?

Animals obtain the chemical energy known as "food energy" from their food in order to maintain their metabolism, which includes their muscular activity.

The majority of animals get most of their energy via aerobic respiration, which involves mixing carbs, lipids, and proteins with air or water-based oxygen.

To find the total calories, multiply the given biomolecules grams with their calorie count.

= 42 × 4 + 7 × 9 + 34 × 4

= 168 + 63 + 136

= 367 calories

Therefore, the sandwich provides 367 calories of energy, if it contains 42 g protein, 7 g fat, and 34 g carbohydrates.

What is an exothermic reaction?

When a chemical reaction takes place, energy is transferred to or from the surrounding in the universe. When the energy is transferred to the surrounding, there is a loss of energy, this reaction is called an exothermic reaction, and the temperature of the surrounding increases during this reaction.

The process of dissolving a substance is exothermic when more energy is released when water molecules bond to the solute particles in the solution than is used to break the solute particles apart. Because, more energy is released than is used in this process, the molecules which are present in the solution move faster, and thus results in an overall increase in temperature.

Explain why flask #2 (yeast with glucose) produced more CO2 than flask #5 (yeast with flour). AND how did you know it produced more CO2?

Answers

Answer: Glucose

Explanation:

The carbon dioxide produced in the experiment can be directly related to the energy generated after the fermentation process. The carbon dioxide is the byproduct of the chemical reactions in the ethanolic fermentation. Glucose substrate will yield the highest energy along with the highest producer of the carbon dioxide after the fermentation process conducted by yeast as compared to the fermentation process that was conducted by yeast with flour. The flour will offer a source of carbohydrates including starch and sugars. The yeast will find out sugar in the flour and ferment it. Glucose is readily available sugar for the action of yeast so more production of carbon dioxide is expected from glucose substrate.

Water in the blood helps carry nutrients and gases required foe survival througout the body. Which characteristics of water allow for this action?

A.water has a neutral pH
B.water maintains temperature
C.what expands when it freezes
D.water dissolves many compounds

Answers

Answer:

Water has a neutral pH

Explanation:

None of the others exactly fit in with what this is saying, and water having a neutral pH allows the supplies and nutrients that it carries to stay safe within it throughout the way.

Sorry if this isn't correct or full-fledged explained like I normally do, I saw you said to hurry up and I didn't do my normal research and whatnot.

Anyways, hope this helped!

Sources: N/A

The characteristic of water that allows this process of carrying nutrients and gases is water has a neutral pH. Thus, the correct option for this question is A.

What are the characteristics of water?

The characteristics of water are as follows:

It is a universal solvent. Due to the partial positive charge on hydrogen and partial negative charge on oxygen, it is a polar molecule. It has high heat capacity and high heat of vaporization. It has properties like cohesion and adhesion. Its solid form is less dense as compared to liquid.

Due to having the property of neutral pH, water significantly performs movement across the entire body with the help of blood.

It does not form any barrier with the differences in the level of pH. So, along with blood, water carries nutrients and gases that must be required for proper survival throughout the body.

Therefore, water that has a neutral pH is the characteristic property that allows the carrying of nutrients and gases required for survival throughout the body.

Which statement best describes the movement of ocean waves? Water moves across the ocean's surface water remains in the same place as wave (energy) travels through it water moves because there is a difference in density of the water creating a wave none of these

Answers

Answer:

water remains in the same place as wave (energy) travels through it

Explanation:

Winds influence the ocean and its movements. Air current running on the ocean surface transfers energy to water. A wave is nothing else than energy. When the winds provide energy to the water surface and produce waves, it occurs a particular water molecules´ motion. They move in circles from up to down, up to a certain depth, and go back to the surface. And they do so while energy from the wave is passing through. Waves are the ones that move through the ocean until they reach the shore, where the energy is transferred to land. Water molecules remain in the same general area, while energy travels from molecule to molecule as a wave.
