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.
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.

explain the importance of meiosis in the life cycle and evolution of the water mold?
Answer:
The diploid form of the mold is called the zygospore, which is were meiosis occurs. Some protists life cycles switch between diploid and haploid phases. This is known as alteration of generations. The water mold reproduces asexually by producing spores, which are diploid. The water mold reproduces sexually by producing gametes which are haploid.
Explanation:
Answer:
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.

Which of the following is an accurate description of a positive feedback loop? SC.912.E.7.7
A.
It is uncommon in nature and it makes systems stable.
B.
It is common in nature and it doesn’t change the stability of systems
C.
It is uncommon in nature and is usually caused by humans
D.
It is common in nature and it makes systems stable
Regulatory functions such as feedback loops are very common in nature and happen thousands of times every day within our bodies alone.
A feedback loop is one of the methods by which biological organisms regulate functions. Feedback loops are a self-regulatory means through which the output of a system is then used as the input. Feedback loops can be of two types:
Positive FeedbackNegative FeedbackA positive feedback loop is one in which the system is stimulated to increase the production of a product. For example, the low levels of an enzyme in the blood will cause the body to produce more of that enzyme in a positive feedback loop. A negative feedback loop is just the opposite, in which high levels will cause a decrease in production.
Feedback loops are a vital part of maintaining homeostasis and for the survival of all organisms. Therefore, we can conclude that option D is correct in stating that feedback loops are common in nature and make the system stable.

The graphs below show the change in temperature and salinity of a region of ocean as an instrument is lowered below the surface. Depth is measured in kilometers below the surface, temperature in degrees Celsius, and salinity in parts per thousand.Image of two graphs. The left graph has the x-axis labeled temperature (degree C) ranging from 0 to 10. The y-axis is labeled depth below surface (km) ranging from -1.8 to 0. The line on graph goes up vertically starting at about 2 degree C on the x-axis and -1.9 km on the y-axis. The vertical line goes up staying at about 2 degree C and climbs from -1.9 km to about -0.8 km. The line starts to shift right at -0.6 km. The line shifts to the right from 2 degree C to 5 degree C. The line shifts to right more starting at -0.5 km and reaches 10 °C around -0.2 km. The line continues up vertically after -0.2 km. The right graph has the x-axis labeled salinity ranging from 33.8 to 34.6. The y-axis is labeled depth below surface (km) ranging from -1.8 to 0. The line on the graph starts at 34 on the x-axis and 0 km on the y-axis. The line starts to shift to the right at -0.1 km and levels out at 34.2 on the x-axis. At -0.2 km the line shifts to the left and continues to shift left until it reaches -0.5 km.

What drives surface currents?
differences in air temperature
differences in climate
differences in water density
differences in water salinity
Answer:
WHAT DRIVES SURFACE CURRENTS?
Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth's rotation, and the position of landforms that interact with the currents.
DIFFERENCES IN AIR TEMPERATURE.
Movement of air due to differences in temperature between two locations is known as convection or advection. Convection is the term commonly applied to vertical movement of air, whilst advection is used in the context of horizontal displacement of air.
DIFFERENCES IN CLIMATE.
Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time. Climate change refers to long-term changes.
DIFFERENCES IN WATER DENSITY.
High temperature makes water less dense. As water gets warmer, its molecules spread out, so it becomes less dense. As it gets colder, it becomes denser. Most chemicals get denser when they turn from a liquid to a solid, but water is different.
DIFFERENCES IN WATER SALINITY.
As we have seen, most differences in salinity are due to variations in evaporation, precipitation, runoff, and ice cover. All of these process occur at the ocean surface, not at depth, so the most pronounced differences in salinity should be found in surface waters.

the allowance for uncollectible accounts is a contra account to
The allowance for uncollectible accounts refers to a company that accepts the risk of giving credits to those who may not pay it back. These debts are written off as uncollectable and are a contra asset on the balance reports.
Uncollectable accounts are also often referred to as doubtful accounts. This implies that the company that is giving the credit accepts the possibility that this entity may not return the money. This results in a loss for the company as is recorded as a contra asset on the balance sheets for the company. Some ways for companies to control this loss are:
Establishing requirements for creditsUsing credit collectors to claim large debtsLimiting amount of loss permitted based on historical and industry records.A contra asset or contra account is an account on a companies balance sheet that decreases the balance of certain assets. Contra derives from Latin and means against. Meaning this is an account that goes against the positive balance of the company, it subtracts from the companies earnings.

Solar radiation is a broad word for the electromagnetic radiation that the sun emits. It is also sometimes referred to as the solar resource or just sunshine. A multitude of devices can be used to collect solar radiation and transform it into useful forms of energy, such as heat and electricity.
How much of the Sun do we actually see?Sunlight at Earth's surface is roughly 42 to 43 percent visible (400 to 700 nm), 52 to 55 percent infrared (above 700 nm), and 3 to 5 percent ultraviolet in terms of energy (below 400 nm).The Sun always emits the same amount of energy. Insolation refers to the incoming solar radiation. Seventy percent of solar energy makes it to the planet.99.8% of the mass in our solar system is found in the Sun. Everything, from tiny Mercury to the gas giants to the Oort Cloud, 186 billion light-years away, is kept in place by its gravitational attraction.What would occur if our distance from the Sun increased by 10%?More radiation, ultraviolet rays, heat, and other rays would be directed at our atmosphere. It would be impossible to live. According to my projection, the global average temperature would increase from 16 C to 65 C. (149 Fahrenheit). This would be high enough to prevent most life from existing, yet low enough to prevent water from boiling.The solar system itself, the Sun Between 99.8 and 99.9 percent of the mass of the solar system is found in the Sun.
