The mechanism of the microscope prevents the revolving nosepiece from being lowered to the lower limit when the pre-focusing lever is locked since it reduces the stroke's coarseness.
A pre-focusing lever makes sure the objective doesn't touch the sample and makes focusing easier.The lower limit on coarse adjustment movement is set at the locked position. After focusing on the specimen using the coarse adjustment knob, turn this lever in the direction of the arrow and lock.After switching out a specimen, it is simple to approximate refocus by turning the coarse adjustment knob until it is in the pre-focused position. The objective's vertical movement, which is activated by the fine adjustment knob, is not locked after this; all that's left to do is make fine adjustments with it.learn more about microscope here:

Factor x and y are both required to cause a certain disease. neither x nor y can produce the disease alone. factor x is:_____.
Factor X is necessary and not sufficient enough for causing certain genetic diseases. They are called 'component causes'.
Most of the classic genetic diseases can be explained by 'component cause'. This means that there are two or more different complex factors necessary to cause a single disease and more importantly together only they can form a sufficient cause.
For instance, Phenylketonuria (PKA) is a genetic disease that involves many different genes. This condition can result from a combination of PKA genes (factor A) and a diet high in phenylalanine (factor B).
Both factors are necessary but either one is not sufficient to cause the disease. These factors A and B together form a casual constellation to cause the PKA disease.

What is the compressions-to-ventilations ratio during a 1-person rescue of a child?A distinct established criterion for CPR ratios is necessary for people of different ages. For instance, a baby differs from a child, a child from the average adult, and an elderly person differs from the average adult. To enable artificial circulation, the heart is intended to be squeezed between the chest bone and the backbone. The compression level often equals or is near to two inches, so it applies to all ages and gives or takes a few inches.The compression ratio for a single rescuer doing CPR on an adult, child, newborn, or neonate is 30/2. Despite how small the changes are, they call for immediate action.

What is a typical feature of a small-for-gestational-age (SGA) newborn that differentiates it from a preterm baby with a low-birth-weight
Gestational age was calculated from the report of the mother's last normal menstrual period (LMP), and preterm delivery was defined as delivery at <37 completed weeks of gestation. SGA was defined as birth weight <10. percentile for gestational age and gender using INTERGROWTH standards
What is Small for gestational age?Small for gestational age (SGA) is defined as a birth weight less than the 10th percentile for gestational age. SGA children are divided into two main groups: constitutionally normal children who are SGA and children who are SGA due to growth restriction with a birth weight below the expected optimal birth weight. Constitutionally normal infants have a normal birth weight less than the 10th percentile due to inherent factors such as maternal height, weight, ethnicity, parity, and these infants are not at increased risk of perinatal mortality and morbidity. SGA and fetal growth restriction (FGR) are used interchangeably but are not synonymous. Many SGA infants have FGR, and many FGR infants are also SGA. However, SGA cannot be used as a marker for FGR because some infants with FGR will have a birth weight greater than the 10th percentile. Therefore, when differentiating between SGA and FGR, it is important to use fetal growth curves adjusted based on constitutional factors to differentiate normal SGA infants from those with FGR.
