The correct option is HEREDITY.
All living organisms reproduce and give birth to young ones either by mean of asexual reproduction or by mean of sexual reproduction. During the course of reproduction, genetic materials from the parents are transferred to the newly reproduced young ones, so that they possess some of the same characteristics that their parents possess. This process of inheriting traits from parents is present in all living organisms and it is one of the indicators by which living organisms are identified.
Answer:
<em>23%</em>
Explanation:
The maximum number of individuals of a population that a particular ecosystem can hold is known as the carrying capacity of that particular population.
As the reptiles living in the ecosystems, without the mammal species, had to compete less, hence there carrying capacity was more in such areas.
There s a difference of 23% in the carrying capacity fir reptiles in the areas where the particular species of mammals were present.
240+ 150= 390
240-150= 90
90 divided by 390 and then multiplied by 100 gives 23%.
Answer:
The cell was first discovered and named by Robert Hooke in 1665. He remarked that it looked strangely similar to cellula or small rooms which monks inhabited, thus deriving the name. However what Hooke actually saw was the dead cell walls of plant cells (cork) as it appeared under the microscope.
Both chloroplasts and cyanobacteria get their energy from performing photosynthesis which led researchers to propose that chloroplasts evolved from cyanobacteria.
Answer:
Explanation:
They could have conducted the experiment at least thrice for each sample (sand and water) OR done the experiment once but at least in triplicates (i.e obtained six identical 1000 ml beakers; with three beakers for each sample, all ran at once). Also, the same volume of sand put in three of these beakers should be the same volume of water put in the remaining three beakers as rightfully done in the experiment.
The essence of conducting the experiment at least thrice for each sample (sand and water) or done the experiment once but at least in triplicates is to be able to subject there recorded data to statistical analysis; this affords them the opportunity to remove/reduce all forms of error the experiment could have been exposed to during the course of the experiment.
Possible errors include (but not limited to) error due to parallax while taking the volumetric measurements and timing errors.
