The answer is Charles Darwin. He was the first to theorize evolution from a common ancestor.
Answer:
Option B
Explanation:
An economics footprint can be described as a measure of biological productivity.
Ecological footprints show a comparison of the rapidness of our resources consumption and waste generation to the rapidness of natural absorbing these wastes and also including our carbon emission.
Thus, one of the characteristics of ecological footprints is a measure of our biological productivity.
Answer:
The correct answer is ''The scientific study of heredity''
Explanation:
Genetics is a branch of biology that studies how hereditary characters are transmitted from generation to generation and the diversity that exists among living beings. Inheritance is the physical and biological characteristics that we share with our family and that can determine our appearance and our biological characteristics, that is, our phenotype (eye color, skin type, etc.) as well as our internal characteristics. All of this is largely derived from our genetic components, that is, our genotype.
Muzzle velocity is a vector quantity which means it has direction and magnitude. Generally speaking, any velocity is classified as a vector quantity, a value with direction and magnitude. Velocity is the rate of change of the location of the object moving and is specified by its direction and speed. Since muzzle velocity is a velocity then it would surely be a vector quantity. Muzzle velocity is the speed of a bullet as it is leaving a muzzle of a gun in a the direction where the gun is pointed. It would have a value ranging from about 120 m/s to 370 m/s in muskets to 1200 m/s for modern rifles.
<h2>Mark and recapture method</h2>
Explanation:
Mark and recapture is a technique to measure the size of a population before fishing and hunting season;commonly used by fish and wildlife managers
- It involves the marking of number of individuals in a natural population,returning them to that population followed by recapturing some of those as a basis for estimating the size of the population at the time of marking and release
- Population size can be estimated as(N)=M*T/R
here,M=initially marked;T=total in sample second;R=marked recaptures
There are certain assumptions to this method
- Population is assumed to be closed which means no new individuals were born or immigrated into the population and none died or emigrated from the population
- The chance for each individual in the population to be caught are equal and constant for both the initial marking period and the recapture period
- One of the assumption of this method is that sufficient time must be given between the initial marking period and recapture period for all marked individuals but time period should not be very long
- Animals do not lose their mark
The tags in the given question were estimated a year there is a chance that old marked tags population might have died or emigrated(the longer the time interval the greater the chance) and hence it becomes an "open" population which violates the first law
If proportion of population changes then marked recapture method formula won't turn out be applicable
