Which curve best describes survivorship in marine mollusks?
a Type III curve -The greatest mortality is experienced early on in life, with relatively low rates of death for those surviving this bottleneck. This type of curve is characteristic of species that produce a large number of offspring
Type 2 survivorship curve?
A type 2 survivorship curve implies a roughly constant mortality rate across all age groups of the species.

Which survivor ship curve would represent frogs?
A type III survivorship curve is a good fit for frogs. The curve shows a high mortality rate early in life with a far lower mortality rate later in adult life. The curve is typical for species that have large numbers of offspring. Many species produce large numbers of eggs although some produce only one egg at a time. The morality rates are likely to vary depending on the number of eggs produced.
What is a detailed time line of health improvement for your lungs and overall health after quitting smoking?
seven years Seven years after quitting smoking, the overall mortality curve of a former smoker levels out to be equal to (to have the same slope as) a lifetime non-smoker. This is actually somewhat misleading. Many people will read this statement and think "Seven years after I quit smoking my mortality will be the same as if I never smoked." Absolutely not true. The slopes of the mortality curves are equal after 7 years, but the former smoker is going to have a higher mortality. It would be good to have a picture here. The smokers' curve is going to be higher at every age due to the damage done to the lungs. If you plot mortality on the Y axis and age on the X axis, you will have two parallel lines, with the smoker curve on top, showing a higher mortality at every age.
What does mortality in research studies mean?
In research studies, mortality refers to the loss of participants during the course of a study — not necessarily due to death, but due to dropout, withdrawal, or unavailability of subjects. 🔍 In Research Context: It’s also called “attrition”. It can affect the validity and reliability of the results. 🔄 Two Types: Experimental Mortality (or Subject Mortality): When participants leave before the study ends, which may cause uneven groups or bias. Mortality Threat (to Internal Validity): If the dropouts differ significantly from those who remain, it can distort outcomes and make it unclear whether changes are due to the treatment or the dropout pattern. 🧠 Example: If 20 people start a weight loss program study and 5 quit halfway, the results from the remaining 15 may no longer fairly represent the original group — especially if the 5 who quit were struggling the most.

What does a skull in a spade mean?
A skull in a spade symbolizes death and mortality. It is often used as a warning or reminder of our own mortality.
What type of survivorship curve does cheetah exhibit?
Cheetahs exhibit a Type III survivorship curve. This means that they have a high mortality rate among the young, but those that survive their early years have a higher chance of living longer.
What does the curve of thumbs mean?
The curve of your thumb is the part where it looks rounded, at the base of your thumb.
Is it true that a normal distribution curve is symmetric about the mean?
yup, it's a bell curve
What are the properties of a standard normal curve?
It is a normal curve with mean = 0 and variance = 1.
What is the mean of standard normal curve?
The mean of a standard normal curve is 0. This curve, which is a type of probability distribution known as the standard normal distribution, is symmetric and bell-shaped, centered around the mean. Additionally, the standard deviation of a standard normal curve is 1, which helps define the spread of the data around the mean.
