Water at 4 degrees centigrade has the highest density of all other water temperatures. This is why ice (whose temperature is below 0 degrees) floats on very cold water. This phenomenon is significant in the Artic and Antarctic where ice shelves float on cold ocean waters in the poles. Animals that live in these regions (such as seals and polar bears) use these ice shelves as hunting platforms.
In the black-scholes option pricing model, an increase in the risk-free rate (rfr) will cause an increase in call value and a decrease in put value.
The Black-Scholes Pricing Model for Options is a method for calculating the theoretical value of a call or put option based on six factors: volatility, option type, price of the underlying stock, time value, strike price, and current risk-free rate.
Given that call options have a positive Rho, they typically increase in price significantly as interest rates rise. Due to its negative Rho, put options tend to lose some of their value as interest rates rise, all other things being equal.
Therefore, In the black-scholes option pricing model, an increase in the risk-free rate (rfr) will cause an increase in call value and a decrease in put value.

Meiosis. Sexual recombination. Crossing over. Independent assortment. Mutations.
The two MAIN sources would be genetic(sexual) recombination and mutations. Mutations allow for genetic variation, while genetic recombination allows for genetic shuffling. :)
Answer:The raw materials required for the process of photosynthesis are carbon dioxide, water and solar energy.
The carbon dioxide present in the atmosphere diffuses into the leaf through stomata.
Water is obtained from the plant roots.
Solar energy is obtained from the sun which gets trapped by the chlorophyll pigment present in the leaves.
Explanation:
