Answer 1

Answer:

Answer:

The lower esophageal sphincter, or gastroesophageal sphincter

Explanation:

The esophagus is a fibromuscular tube that is involved in the food transport via peristaltic contractions (radially symmetric muscle contractions and relaxation).

Most modern forms of transportation are powered by fossil fuels. Carbon dioxide, methane, carbon monoxide, and other gases are released into the atmosphere during the production and combustion of these fuels. How might these gases cause climatic changes? These gases have no effect on atmospheric temperatures, so they are unable to cause any type of climatic changes. These gases cause more water vapor to condense, making climates wetter than they were in the past. These gases reduce the amount of thermal energy escaping into space, effectively warming the atmosphere.

When measuring the length of an earthworm,which graduation would allow for the most accurate measurement?

Answers

Answer:

A Ruler scale

Explanation:

Graduation refers to the tool that measures the length of any particular object. It contains a mark that points to the exact value on a visible scale. These are the linear scales frequently used and they are both straight as well as curved. The units are usually in inches, millimeters, and centimeters.

The ruler scale is often used to measure the length of an earthworm because it gives the most accurate measurement.

I would chose centimeter because it is the smallest and most precise of the measurements! :)
