Answer:
água, amônia, gás carbônico
Explanation:H2O-> porque são dois átomos de hidrogênio e um de oxigênio; NH4-> poque é um átomo de nitrogênio e quatro átomos de hidrogênio e CO2->porque é um átomo de carbono e dois átomos de oxigênio

Answer: sand, silt, and clay.
Answer : The correct option is "record 10.00 ml in the notebook after using it."
Explanation :
If an instrument has "10 mL TD" written on it, that means the instrument is meant To Deliver (TD) 10 mL of volume.
Therefore the option that has 5.00 mL is not correct.
"+/- 0.01 mL" indicates the precision of the instrument. We know that no measurement is 100% accurate and there is always some uncertainty associated with any measurement.
Here, 0.01 indicates the uncertainty in the measurement.
When we have 0.01 mL , that means the instrument can record precisely to the hundredths place.
The more the significant figures, the greater is the accuracy of the measurement.
Therefore when we use an instrument that has "+/- 0.01 mL" written on it, we should record the reading as 10.00 mL
1. Answer:
B) An allele is one form of a gene.
Explanation:
- <em><u>An allele refers to an alternative form of a gene. In other words it is one of the form of a gene.</u></em>
- <em><u>A gene may have two alleles, where one of the allele is a dominant allele and the other is a recessive allele. </u></em>
- A homozygous organisms may be dominant or recessive, a homozygous recessive contains two recessive alleles while a homozygous dominant contains two dominant alleles.
- A heterozygous organisms contain one dominant allele and one recessive allele.
2. Answer;
B) Alleles
Explanation;
- <em><u>According to Mendel genes are inherited in pairs of alleles that behave in a dominant and recessive pattern. </u></em>
- <em><u>Alleles are alternative forms of a gene. </u></em>
- A gene may have two alleles, where one of the allele is a dominant allele and the other is a recessive allele.
- A homozygous organisms may be dominant or recessive, a homozygous recessive contains two recessive alleles while a homozygous dominant contains two dominant alleles.
