The substance that yields a Cation plus the Hydroxyl ion in water is a Base. 
A Cation is a positively charged ion. A Hydroxyl ion is an ion with a negative charge and is made up on one oxygen atom and one hydrogen atom. Bases are substances that promote chemical reactions. Dissociation is a process in which ionic compounds split into smaller particles. 
<span>In this case, the base acts by dissociation to yield a Cation plus a Hydroxyl ion in water. </span>

Juliette [100K]

The correct answers are options:

It insulates the complex in the winter.

It provides passive cooling in the summer.

The Fusionpolis is a building present in the Singapore. The building is covered by the spine vegetation. The spine vegetation is well known for the insulation against the heat, this makes them best for maintaining the temperature in the building. These spines provide the insulation in the winters, when the outside atmosphere is too cold, and in summers, the transpiration of the spines help in cooling down the temperature of the building.

Skeletal remains are discovered at an archeological site. X-rays of the femur show evidence of a thin epiphyseal plate. This bon
Basile [38]

Answer:

The correct option is D. 18 year old male

Explanation:

The epiphyseal plate can be described as a disc of cartilage that is required for the growth of bones. The epiphyseal plates get fused in females at a very early age, most probably between the ages of 13 to 15. In males, the epiphyseal plates fuse a litter later at about 15 to 18 years.

Hence, the presence of epiphyseal plates in the femur would prove that it was present in an 18-year-old male.

All the other options would be false because they won't contain an epiphyseal plate.

Answer:

The average density of deer in 1923 was 1 deer per 8 acres

Explanation:

Given -

In 1923, the population of deer rose to 100,000

The density of any species is equal to total population divided by total area of the land in which this population is residing.

d= \frac{P}{A}

Where d represents the density

P represents the population and

A represents the area of land

Substituting the given values in above equation, we get -

d = \frac{100,000}{800,000} \\d= \frac{1}{8}

Thus, the average density of deer in 1923 was 1 deer per 8 acres
