a) 67000 b) 0.20 c) 52.8010 d) 3.17000 are the answers respectively.
Distance is a physical quantity which is measured in meter. If a man travel then it is measured in meters that defines that how much he travel from one point to another point for all these type of things we use to measure distance.
Centimeter is also a physical quantity which is use to measure distance. 1 centimeter is equal to 0.01 meter and 1 centimeter is equal to 0.00001 kilometer.the kilometer is large quantity to measure distance while centimeter is smaller quantity to measure distance.
Kilometer is also a physical quantity which use to measure the distance 1 kilometer is equal to 1000 mtr and 1 kilometer is equal to 100000 centimeter.
For above conclusion, we easily states that the kilometer is large quantity to measure distance while centimeter is smaller quantity to measure distance. Centimeter is also a physical quantity which is use to measure distance. 1 centimeter is equal to 0.01 meter and 1 centimeter is equal to 0.00001 kilometer.
Therefore, a) 67000 b) 0.20 c) 52.8010 d) 3.17000 are the answers respectively.

Molecular clocks
Molecular clocks use the relationship between the DNA of several groups of organisms to evaluate how long ago they diverged evolutionarily from one another. Therefore, option (4) is correct.
The molecular clock can be described as a figurative term for a technique that utilizes the mutation rate of biomolecules to determine the time when two or more life forms diverged. The biomolecular data used are usually nucleotide sequences for DNA, RNA, or amino acid sequences for proteins.
The benchmarks for calculating the mutation rate are often fossil or archaeological dates. The molecular clock is commonly used in molecular evolution to estimate times of speciation or radiation.
The molecular clock can only give one time period as it cannot assign concrete dates. For viral phylogenetics and ancient DNA studies, the areas of evolutionary biology, the intermediate samples can be utilized to more precisely calibrate the molecular clock.

Answer: To find Dave's speed, you can use the formula for speed, which is:
Speed = Distance / Time
In this case, Dave ran 2000 meters in 25 minutes. First, you'll need to convert the time to hours, as speed is typically measured in meters per second or meters per hour. There are 60 minutes in an hour, so:
25 minutes = 25 / 60 = 5/12 hours
Now, you can calculate Dave's speed:
Speed = 2000 meters / (5/12) hours
To divide by a fraction, you can multiply by its reciprocal (flip it):
Speed = 2000 meters / (5/12 hours) = 2000 meters * (12/5) hours
Now, calculate the speed:
Speed = 4800 meters per hour
So, Dave's speed is 4800 meters per hour.

I just took the test, the answer is A. 305,760 J, good luck.
(1) Fidel Castro was removed from power.
(2) Cold War tensions increased.
(3) The United States announced its Good
Neighbor policy.
(4) The communist government in Nicaragua was
overthrown.
2) Cold War tensions increased.
The Bay of Pigs invasion was carried out by Cuban exiles that had been trained by the United States' Central Intelligence Agency (CIA). The Cuban counter revolutionaries failed and Kennedy was embarrassed. Within just days, the force of exiles was soundly defeated by the Cuban Revolutionary Armed Forces, commanded by Fidel Castro. In the aftermath of the Bay of Pigs affair, Cuba requested that the USSR, as its communist sponsor, place missiles in Cuba to deter further US-sponsored action against the Castro regime.
