Work is said to be done when an object moves due to a force applied. Work is calculated by multiplying the force applied and the distance traveled due to the force. It is expressed as:
W = Force x distance
W = 84 J = F (7.0 m)
F = 12 N
Hope this answers the question.
Answer:
6 hours
Explanation:
after death every hour drops to 1.5 the temperature so if you multiply 6 * 1.5 it equals 9 and if you subtract that the 97.6 which is the average heat temperature of the adult then you will get 88.6 degrees which would be around your question
Answer:
It is true to say that by using cuttings, exact genetic characteristics can be maintained, because the cuttings retain the same genetic information about the plant from which they were extracted.
Explanation:
Cuttings are buds or branches extracted from a plant to obtain a plant of the same species, through a type of asexual reproduction.
Once separated from the "progenitor" plant, the cutting is provided with a suitable medium for growth, and will have the possibility of growing roots, developing and growing as an independent plant, with the same genetic characteristics of the original plant, as if it were a clone.
In this reproductive process, man intervenes.
Answer:
The correct answer is - option 2, 3, and option 5.
Explanation:
Biological evolution is the change in genetic level of an individual population that is developed or inherit over a period of time and several generations. Changes can be minute, large, can be identified or not noticeable.
In the given question some of the examples of biological evolution are given such as O genotype individuals increases due to the reduction in population size in the small human population, similarly, one species diverged into two different species on the basis of the adaption they developed in island. Sickle cell anemia frequency is also is an important example of the as it decreases over time.
Thus, the correct answer is - option 2, 3, and option 5.
Answer:
It would harm the few plants that benefit from mutualistic relationships with mycorrhizal fungi
Explanation:
Mycorrhizal relationship is a symbiotic relationship between fungi and the roots of higher plants. While the plant provides the fungi with food, the fungi supply the plant with nutrients and water extracted from the soil.
<em>Hence, if a wide-spectrum fungicide is used in a forest and it kills all the fungi in the forest, it will affect all the plants that share beneficial relationship with fungi in the forest.</em>
