3. Does your skate park playground ramp design support the law of conservation of energy? Use
nlexa [21]

Skate park is a good example that maintains the law of conservation as skater neither creates nor destroys energy.

Explanation:

As per the law of energy conservation, energy cannot be created nor can be destroyed but it’s form can definitely be changed. This theory can be well justified by the example of skate park playground. According to the rules of this law a skater can never go high more than 2 meters on the ramp’s other side because it has that gravitational energy potential.  

With every drop of the skater on the ramp the potential energy of the skater changes into kinetic energy. This two sides of the law justifies the fact that skate playground should be designed in such a way that it supports the law of conservation of energy.

A bacterial cell that contains an outer membrane and periplasmic space stains pink to red on Gram stain. Which one of the follow
anastassius [24]

Answer:

a. No discrepancy is present; organisms that contain an outer membrane and periplasmic space should stain pink because of their cell wall composition.

Explanation:

Gram stain is the staining method used to differentiate bacterial species into two groups, gram-positive and gram-negative bacteria. Factors that will differentiate gram-positive from gram-negative include the coloration of bacteria, the composition and chemical and physical properties of cell walls. In these tests, bacteria that have an outer membrane and a periplasmic space are considered gram negative and pink in color (sometimes similar to red) due to their cellular composition. For this reason we can state that there is no discrepancy present in the bacteria exposed in the question; Because this bacterium has an outer membrane and a periplasmic space, then it is normal for the bacteria to turn pink due to its cell wall composition.

In what way do adaptations help the survival of a species?
ozzi

Adaptations help the survival of a species as "It increases the biodiversity of the species".

<u>Answer:</u> Option C

<u>Explanation:</u>

The phenomenon that support the organisms to find similar and favourable environment to acquire food, build home, satisfy with weather, feel safe and attract mates to produce more offspring in order to improve evolutionary fitness is called as an "Adaptation".

The three main forms of adaptations are behavioural, structural, and physiological adaptations that are based on the way how genetic variation get communicated. Many species have all those types of combinations. For an instance, behavioural adaptations are bird's calling and migration.
