Answer:

Answer is C. A number of relevant variables are assumed to be constant.

Explanation:

The term "other things equal" is a Latin term "ceteris paribus". This term is very important in economics because it has solved the issue of having difficulty in isolating different variables that may change the outcome of ones study. That is, independent variables that are affecting dependent variables.

Which is a characteristic of the littoral zone of lake erie?

Lostsunrise [7]

<span>Wide variety of fish species. It always includes this intertidal zone and is sometimes used to mean the same as the intertidal zone. Though, the meaning of "littoral zone" can be overall well beyond the intertidal zone. The littoral zone is the same as a sea, lake or river that is close to the shore. In coastal environments the littoral zone extends from the high water mark, which is very rare inundated, to shoreline areas that are permanently submerged.</span>

Describe the relationships among amino acids, chromosomes, proteins, and genes in the cells of a jackalberry plant. Make sure to

nasty-shy [4]

Answer:

The jackalberry plant is a multicellular organism whose cells contain chromosomes. The chromosomes contain genes that are transcribed to produce messenger RNAs, which are then translated into proteins

Explanation:

The Jackalberry tree is a plant, i.e., a multicellular organism. Multicellular organisms have chromosomes in the nucleus of each cell. A chromosome is a long DNA molecule that contains part (or even all) of the genetic information of a particular organism. Genes are specific segments of the chromosomes, which are expressed in a process called 'transcription' where a gene is used as template to synthesize an RNA molecule, usually a messenger RNA (mRNA). Subsequently, these mRNAs are used to synthesize proteins by a process called 'translation'. In an mRNA molecule, each specific triplet of nucleotides is known as a codon and corresponds with a specific amino acid during protein synthesis. Thus, the mRNA sequence dictates the correct order of amino acids (i.e., the building blocks of proteins) in the polypeptide chain.

In a plant species, you notice that purple and yellow leaf colors, as well as hairy and smooth stems segregate independently. Yo

Reptile [31]

Answer:

The required answer is given below:

Explanation:

a) Assuming C is the gene for leaf color and S is the gene for the stem type.

then, the genotypes for each parent would be-

Yellow leaves, hairy stem parent: ccSs

Purple leaves, hairy stem parent: CcSs

b) Expected ratios of the progeny as below:

68 yellow leaves, hairy stems: 3/8

66 purple leaves, hairy stems: 3/8

22 purple leaves, smooth stems: 1/8

25 yellow leaves, smooth stems: 1/8

Hence, the ratio is - 3:3:1:1

It might possible that independently assorting single gene pairs could control traits, and that one of the alleles in each pair is dominant.

c) The general formula for calculating X2:

X2 = the sum of (O - E)2/E,

(where O = observed number)

(E = expected number)

So,

(68 – 68)2 /68 + (66 – 68)2/68 + (22 – 23)2 /23 + (25 – 23)2/23

= 0.276

X2 = 0.276

The chi-square statistic too small, Hence the hypothesis is acceptable.
