Answer: He grew a willow tree in a weighed amount of soil. After five years, he discovered that the willow tree weighed about 74 kg more than it did at the start. As the weight of the soil had hardly changed, van Helmont concluded that plant growth cannot only be due to minerals from the soil.
Answer:
The answer is D a retrovirus inserts DNA into the host cells genes
The organelle the question is referring to is called the chloroplast. I hope this helps; have a good evening!
Answer:
Accurate - Yes
Precise - Yes
Explanation:
Accuracy and precision are two ways to detect the closeness of measured values in an experiment. However, these two terms do not mean the same thing.
Accuracy of a measurement refers to how close a measurement (experimental values) is to a true or actual value while the precision of a measurement refers to how close the experimental or measured values are to one another.
Note that, a measurement may be accurate but not precise or be precise but not accurate.
In the case of the dart board in the image, it is evident that the measured values (represented by darts) are close to the middle target (represents the known or accepted mark). Hence, the measurements are said to be ACCURATE. Likewise, the measured values are also close to one another, meaning that they are PRECISE.
Therefore, the measurements are both precise and accurate.
The answer to the above question is alleles.
<h3>What are Alleles?</h3>
The two nucleic acids in living things that are employed for conveying and storing genetic information are RNA and DNA. The genetic material in living things is called deoxyribonucleic acid (DNA), and it contains sections coding for beneficial proteins and products as well as carrying genetic information from one generation to the next. These chunks are referred to as genes.
However, genes also have a different form that is in charge of the genetic diversity in the qualities they are coding for. Allele refers to a gene's alternative or variant version. In a diploid creature like the human, each trait is encoded by genes that include contrasting pairs of alleles, allowing variation for that specific trait, i.e. two alleles for each gene. For instance, a gene with two alleles that codes for one of the human height traits includes the short variety (t) and the tall variety (T).
