This layer is called the cell wall.

The cell wall is located outside the cell membrane and provides the cells with structural support and protection.  It gives cells rigidity and strength, offering protection against mechanical stress.

In most cells, it is flexible, meaning that it will bend rather than hold a fixed shape, but has a lot of tensile strength which is necessary to be able to withstand internal osmotic pressure.

Cell walls are found in plants, bacteria, fungi, algae and some archaea.

Sand that extends from a coast into open water is called a barrier spit. <br> a. True <br> b. False
AysviL [449]
<span>It is True - Sand that extends from a coast into open water is called a barrier spit.

Barrier spits are formed when there is a deposit on the shoreline due to the lateral movement of water.

The waves are known to hit the shoreline at a particular angle which cause the lateral movement of water accompanied with the sedimentation along the coastline in the direction of the wave motion.</span>

​(f) contact a local hospital and ask them the percentage of the population that is blood type o. why might the results​ differ?
Fudgin [204]
Contacting a local hospital and asking them the percentage of the population that has blood type O will generate different results. 

The factors that we have to consider why there is differing results are:
1) location of the hospital
2) nationality of their patients
3) number of their patients

I am assuming that the population that question is referring to is the number of patients in the local hospital. The bigger the population, the smaller the effect a unit has on the whole and vice versa. 

I read an article that states that 37% of the U.S. population has O+ blood type. These people are usually of Hispanic descent or some Asian descent. So, if a hospital is in a locality that has a majority of Hispanic or Asian patients, its percentage will be higher than a hospital that is located in a Caucasian-populated area. 

Aside from Type O+ (most common), blood types also include: O-, A+, A-, B+, B-, AB+, and AB- (rarest blood type)
