We gain energy from eating plants. Plants can't create their energy; they must first get it from the Sun.

The correct answer is true and first.

The statement is true. According to the first law of thermodynamics.

Energy is termed as quantitative property which is transferred to an object so as to heat. Energy cannot be destroyed or created but it can be converted to a form of an object.

There are different forms of energy. For example, kinetic energy which is a moving object, elastic energy which is got by stretching solid objects and stored, chemical energy which is released when fuel is burned.

Inorder for living organisms to stay alive they should have available energy. For example, human gets energy from food. Radiant energy drives ecosystem and earth's climate whereby the earth receives it from geothermal energy and sun.

This statement is true according to the first law of thermodynamics. The correct option among all the options that are given in the question is the first option. The other choices given in the question are incorrect and can be avoided. I hope that this is the answer that has actually come to your great help.

How many possible open reading frames (frames without stop codons) are there that extend through the following sequence? 5'... C

fenix001 [56]

Answer:

There are 4 reading frames without stop codons.

Explanation:

1) To find the possible reading frames you need to separate your sequence in codons (trios) for the 5'-> 3' sense, first, excluding the first nucleotide, then excluding 2 nucleotides and then not excluding nucleotides.

5'... C TTA CAG TTT ATT GAT ACG GAG AAG G... 3' NO STOP CODON

5'... CT TAC AGT TTA TTG ATA CGG AGA AGG... 3' NO STOP CODON

5'... CTT ACA GTT TAT TGA TAC GGA GAA GG... 3'

2)Then you find the complementary sequence (which you already have)

3'... GAA TGT CAA ATA ACT ATG CCT CTT CC... 5'

3'... GA ATG TCA AAT AAC TAT GCC TCT TCC... 5'

3'... G AAT GTC AAA TAA CTA TGC CTC TTC C... 5'

3) Next, you have to obtain the reverse complementary

CCT TCT CCG TAT CAA TAA ACT GTA AG NO STOP CODON

CC TTC TCC GTA TCA ATA AAC TGT AAG NO STOP CODON

C CTT CTC CGT ATC AAT AAA CTG TAA G

4)Now you need to find start (AGT in terms of DNA) and stop codons(TAA, TAG, TGA, also in terms of DNA), in 5->3 and de reverse complementary.

As you can see, you have for open reading frames that lack of stop codon, unfortunately, they also lack of AGT, the start codon.

I added a table where you can find thestart and stop codons as well as the proteins that they translate to in terms of RNA.

I hope you find this information interesting and useful, good luck!

What is the purpose of using a pedigree?

Fiesta28 [93]

Answer:

The pedigree chart are used to check the mode of inheritance of certain trait.

Explanation:

The pedigree is used to know the probability of the offspring getting a particular disorder or condition. It also help to discover the location of the defected gene. And through it can also be predicted that weather it will be a dominant or a recessive trait. For this pedigree data of several generations are required. Here, the phenotype ratios of the offspring can be accurately determined only when the genotypes of the parents are known.
