What structure is common to all five kingdoms of living organisms?A. DNA
B. Nucleus
C. Cell Wall
D. Mitochondria

I know it is not C-Cell Wall.

Answers

Answer 1
Answer: The five kingdoms of living organisms are Monera, Protista, Fungi, Plantae and Animalia. Monera is for single-celled individuals which just absorb nutrients from the cell wall. Protista is for protists, fungi is for muticellular organisms, plantae is to plants and animalia is to animals. The common structure among them is DNA>

Which equation describes a parabola that opens up or down and whose vertex is at the point (h, v)? A. x = a(y - v)2 + h B. y = a(x - h)2 + v C. x = a(y - h)2 + v D. y = a(x - v)2 + h

Answers

The right answer for the question that is being asked and shown above is that: "B. y = a(x - h)2 + v" The equation that describes a parabola that opens up or down and whose vertex is at the point (h, v) is that B. y = a(x - h)2 + v

Answer: B. y=a(x-h)^2+v

All organisms contain DNA, and every organism's DNA is made of the same four nucleotides. The differences between organisms is simply based on the order of these nucleotides. Since all organisms have the same basic, universal structure for DNA, which of these must also be universal? A) All organisms have the same proteins. B) All living things must have the same amount of DNA. C) All organisms must be genetically identical to each other. D) All codons in all organisms' DNA code for the same amino acids.

Answers

Answer;

All codons in all organisms' DNA code for the same amino acids.


Explanation;

The genetic code is universal such that almost all organisms translate nucleotide sequences of DNA and RNA to amino acids sequences of proteins.

A good example is between Humans and bacteria; A codon with three Thyamine (DNA) ; TTT ,codes for amino acid Phenylalanine.

All codon in all organisms' DNA code for the same amino acids

Why did we make sure to include a start and stop dna sequences for the jellyfish?

Answers

We did  make sure to include a start and stop dna sequences for the jellyfish so that  the Glo gene would be transcribed and expressed and so we can see that we have successfully transformed the cells into which we place the engineered plasmid.

Answer:

Explanation:

The DNA is composed of a sequence of nucleotides, each having a different base (adenine, thymine, guanine, cytosine). This DNA molecule is transcribed into RNA, which has a complementary sequence. Then the RNA will have a base sequence according to the information encoded in the DNA.

A codon consists of three bases together, which code for an amino acid.So each three-letter sequence of RNA corresponds to a specific amino acid, a start or stop codon.

AUG is the codon for methionine, and it is also the start codon, which indicates when the protein synthesis must begin. While UGA, UAA, and UAG are stop codons. Start and stop codons are important because then translation is not started or finished. During protein synthesis, stop codons cause the release of the protein from the ribosome.

So, that the protein synthesis begins and is carried out respecting the reading frame so that the appropriate protein is produced, and that it stops being synthesized when necessary, it is important to have a start and stop codon.

Cellulose-digesting microorganisms live in the guts of termites and ruminant mammals. The microorganisms have a home and food, and their hosts gain more nutrition from their meals. This relationship is an example of _____. See Concept 54A. mutualismB. commensalismC. predationD. parasitismE. herbivory

Answers

Answer: A (Mutualism)

Explanation:

The relationship between termites and cellulose digestive microorganisms is Mutualism. This is because Termites feed on cellulose, which they get from feeding on dry woods.

Termites themselves can not degrade cellulose but the depend on microorganisms in their guts. These microorganisms releases enzymes that solely degrade cellulose.

The symbiotic relationship between termites and cellulose digestive microorganisms is Mutualism because they both depend on each other for survival. Microorganisms would not survive outside of the termite, and the termite would not be able to degrade food if it didn't have cellulose digestive microorganisms to aid in digestion.

A precipitation reaction is a reaction between two aqueous solutions that results in the formation of a __________ compound.

Answers

A precipitation reaction is a reaction between two aqueous solutions that results in the formation of A SOLID compound.

A precipitation reaction is a type of reaction in which two solutions containing soluble salts react together to produce an insoluble salt (solid) called 'the precipitate'. The precipitate occurs as a result of the combination of the cations and the anions in the solutions. Precipitation reactions are usually used in chemistry to determine the types of ions that are present in solutions.

A precipitation reaction is theformation of a solid compound from the reaction between two aqueoussolutions. The solid compound that is formed is called precipitate. The aqueoussolution that causes the formation of the solid compound is called precipitant.
