"In the early days of germ theory, contagious diseases
were thought to be caused by fungi or bacteria. In the 1890's, Dmitri
Ivanovski filtered extracts from diseased tobacco plants and discovered
that the disease could be transmitted to new plants through the
filtrate. He concluded that the disease was caused by particles smaller
than bacteria; the tobacco mosaic virus", is partially correct. Dmitri
Ivanovski discovered that filtered extracts from diseased tobacco plants
could be transmitted to new plants through the filtrate. However, it
was Dutch microbiologist Martinus Beijerinck who, while replicating
Ivanovsky's experiments, proved that the filtrate contained a new
infectious agent. Beijerinck named this agent a virus.
Answer:
Cell cycle consists of interphase and mitosis. During interphase there are 3 phases- G1, S and G2 phases. G1 is the resting phase after previous mitotic phase, S phase is DNA synthesis phase and G2 phase is again resting phase.
DNA synthesis occurs before mitotic phase which is the actual cell division phase and chromosomes are condensed during mitotic phase therefore it's in the chromatin form that DNA is synthesised.

Answer:
C. The North Atlantic Gyre flows in a clockwise direction, so the prevailing current on the Florida coast would be south to north, and it would disperse lionfish up the coast.
Explanation:
See the attached picture. The current that is most likely to act on lionfish near Florida would move from south to north.
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.

Answer:
Tolerance to heat, light and parasite.
Explanation:
Characteristics of tolerance to heat, light and parasite are the three reasons that might use a higher percentage of Nguni on the sector of livestock farmers in South Africa in 2003. The temperature of South Africa is extremely high which can be tolerated by the Nguni cattle due to its good characteristics. The Nguni cattle can bear extreme temperature, high intensity of light and resistance to parasites make it best suited for that environment.
