Question

what is the total magnification of a microscope with a 4x eyepiece and 100x objective lens? * 1 point
96x
25x
400x
104x
which of the following tools is useful to measure large volumes of liquid? * 1 point
my water bottle
erlenmeyer flask
beaker
graduated cylinder
what is the name for the crescent shape made by the top of a liquid when they are placed in a container? * 1 point
meninges
meniscus
tension curve
graduated cylinder

Explanation:

Step1: Recall microscope magnification formula

The total magnification of a microscope is the product of the magnification of the eyepiece and the objective lens. So we need to multiply 4 (4X eyepiece) by 100 (100X objective lens).
$4\times100$

Step2: Calculate the product

$4\times100 = 400$

Step1: Analyze liquid - measuring tools

A water - bottle is not a scientific measuring tool for large volumes of liquid in a laboratory. An Erlenmeyer flask is mainly used for mixing and heating, not the most accurate for large - volume measurement. A beaker can measure liquid volumes but is less accurate than a graduated cylinder. A graduated cylinder is designed for accurately measuring volumes of liquid, and it comes in various sizes including those for large volumes.

Step1: Recall the term for liquid surface shape

The crescent - shaped surface formed by the top of a liquid in a container is called the meniscus. Meninges are the membranes surrounding the brain and spinal cord, and tension curve is not the correct term for this liquid surface phenomenon.
