Why there are different branches of chemistry

1 answer:

5 0

The 5 branches are organic, inorganic, biochemistry, analytical, and physical. There are different branches because they each apply to different parts of chemistry. For example organic chemistry is the study of carbon compounds and inorganic chemistry is the study of non carbon compounds. You can't just have one type of chemistry because these are very different.

1. Which statement is accurate?

valkas [14]

1. Answer:

B) An allele is one form of a gene.

Explanation:

An allele refers to an alternative form of a gene. In other words it is one of the form of a gene.
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.
A heterozygous organisms contain one dominant allele and one recessive allele.

2. Answer;

B) Alleles

Explanation;

According to Mendel genes are inherited in pairs of alleles that behave in a dominant and recessive pattern.
Alleles are alternative forms of a gene.

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.

Explain how deforestation can cause a disruption to the carbon cycle

TEA [102]

Trees and forest play an important role in balancing the amount of Carbon in the atmosphere through the process of photosynthesis where plants make their own food with carbon dioxide, using energy from the sunlight. Therefore, deforestation (cutting down of trees) has an effect on the carbon cycle also the greenhouse gas effect and global warming. Deforestation reduces the removal component of this cycle, thus, increasing the carbon dioxide in the air.

How does the molecular formula of a compound differ from the empirical formula? Can a compound’s empirical and molecular formula

Y_Kistochka [10]

Molecular is every element present in the compound eg C2H6, empirical is the smallest whole number ratio of elements in a compound so that would be CH3 as you divide by the highest common factor. Some compounds only have 1 formula if they are simple or have no common factors. Eg methane, CH4 is its molecular and empirical because its the simplest whole number ratio and includes every element in the molecule

Which two solutions, when mixed together, will undergo a double replacement reaction and form a white, solid substance

Scrat [10]

Which two solutions, when mixed together, will undergo a double replacement reaction and form a white, solid substance?

1. NaCl(aq) and LiNO3(aq)

2. KCl(aq) and AgNO3(aq) answer

3. KCl(aq) and LiCL(aq)

4. NaNO3(aq) and AgNO3(aq)

2 is the answer because AgCl is formed and that is a white ppt.
