Answer:
5 Facts
Explanation:
1. When it comes to chemical weathering, it’s all about chemistry. By looking at the term “chemical weathering,” you can see that a chemical reaction causes something to break down or “weather.” That “something” is rocks and minerals.
2. In chemical weathering, rocks and minerals are reacting to acids, oxygen, carbon and water. That’s why no two rocks ever look exactly the same. It’s also the reason that we have those awesome looking caves and unique rock formations all over the world.
3. While chemical weathering creates nifty formations, the way it breaks down rocks also causes fractures in ancient structures like the Great Sphinx of Egypt. It also causes the surface to break down on gravestones.
4. Chemical weathering types can work separately, but they often work together to create landforms and break down minerals.
5. Acid rain caused by pollution such as factory and car exhaust is another agent of chemical weathering.
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.

Asexual reproduction involves only one parent and the offspring is identical to the parent. An example of an organism that reproduces asexually is Archaea or bacteria. Sexual reproduction involves two parents and the offspring's genes are equally contributed by each parent. An example of organisms that reproduce sexually are some land mammals. The chromosomes of a parent and offspring in asexual reproduction are identical and there is no difference in the chromosomes.
Answer:
frog
Explanation:
frogs live their first part of their lives in water so they need gills but after metamorphosis they live on land so they need lungs.
