Answer:
(-1,-3) on the coordinate grid.
Explanation:
The location from where Sam started his morning walk is 3 units to the left and 2 units up from the origin. This location is indicated by the point (-3,2).
He walked 5 units south and met his friend Joshua.
So, find the point that is 5 units to the south of point (-3,2). Distances north and south on the map represent a change in the y-coordinate. Moving 5 units to the south on the map from point (-3,2) places the new location at point (-3,-3).
Sam then walked 2 units east, where he met his friend, Ethan.
So, find the point that is 2 units to the east of point (-3,-3). Distances east and west on the map represent a change in the x-coordinate. Moving 2 units to the east on the map from point (-3,-3) places the new location at point (-1,-3).
So, Sam met Ethan at the location indicated by point (-1,-3) on the coordinate grid.
Answer:
Since variations in air pressure drive the winds on Earth, isobars also give meteorologists an easy way to assess wind direction and speed. Closely spaced isobars indicate large pressure changes over a small area, causing wind speeds to increase.

Answer:
The living organism is the organism that responds to external stimulus, moves, grows, respire, reproduce, eat and excrete.
Movement - An organism moving from place to place.
Respiration - The release of energy from glucose, occurring in every cell. we respire in order to produce energy
Sensitivity - the ability to detect and respond to stimuli. When we touch something hot, we remove our hand suddenly.
Growth - The production of new cells in an organism.
Reproduction - The process which is used to create offspring similar to parents.
Excretion - The release of harmful substances from the body. We excrete carbon dioxide when we exhale.
Nutrition - Consumption of food for energy. We get nutrition by eating three meals a day.
Sickle cell is a disorder that affects the
molecules in the red blood cells, particularly the hemoglobin. The hemoglobin
is the molecule responsible for transporting oxygen throughout the body. When a
person has sickle cell anemia, the red blood cells are distorted crescent
shapes that do not travel in the bloodstream properly and efficiently. As a
result, this disorder hampers the distribution of oxygen throughout the body.

Anemia is the major characteristic of sickle cell
disorder. A person with sickle cell anemia has low number of red blood cells
that usually begin in early childhood. A person who is experiencing Sickle Cell
Anemia will have multiple and repeated infections, and periodic episodes of
pain. The severity of this condition varies from person to person but is common
in African descents. </span>
