I am very sorry, but all I can provide is that Dawn must have used the balance incorrectly or her other classmates didn't account for certain factors that Dawn did. I would really love to help, but I would need more information.
Radiometric dating reveals the exact (i think its exact) age of a fossil.
Answer:
soil; rice
Explanation:
Bacillus cereus is naturally found in the soil. B. cereus is known to contaminate rice, which, if undercooked and ingested, can lead to gastroenteritis. In this example, the reservoir for B. cereus is the soil, and the source of infection is the rice.
A reservoir refers to the breeding ground or natural habitat of micro living organisms such as bacterias, fungi, worms, etc. Thus, a reservoir hosts or harbours pathogens and usually serves as a source of infection to other living organisms.
On the other hand, a source of infection refers to a contaminated material from which a disease can be acquired by another living organism.
Since you forgot to put capital letters i assume it's like this:
1)A <span>Cross between YyLl (heterozygous parent with dominant traits) and yyll (homozygous parent with recessive traits).
</span><span> 2)offspring YyLl: 400, Yyll: 100, yyLl: 100 and yyll: 400
</span>The recombinant offspring are allele combinations that are not directly inherited from the parents.
The parents combinations:<span>YyLl and yyll,
</span>The recombinant combinations: Yyll and yyLl
The other types are exacly like the parents so they are not recombinant.
answer: Yyll and yyLl
Answer:
DNA, ribosomes, plasma membrane and cytoplasm are the structures that are found in both.
Explanation:
Prokaryotes are the organisms that do not have a nucleus and other membrane-bound organelles and eukaryotes have a membrane-bound nucleus and another membrane-bound organelle.
Apart from this there are some similarities between prokaryotic and eukaryotic cell like both have a highly selective cell membrane, they both have cytoplasm, both have DNA and ribosomes which is responsible for the expression of genes. Therefore DNA, ribosomes, plasma membrane, and cytoplasm are the structures that are common in both prokaryotes and eukaryotes.
