O Amino acids code for DNA. DNA is made up of protein.
O DNA codes for amino acids Amino acids are made up of proteins.
O Amino acids code for protein. Protein is made up of DNA.

Answers

Answer:

Explanation:

The major relationship between protein and nucleic acid is the reproduction of DNA which contains the information on how cells are used together with RNA which helps to make protein. Both nucleic acid and protein they have four biomolecules which are common in both of them.

Short answer: Using a binary code, genes (DNA) specify how proteins (among other things) are to be synthesized.

Analogy: If DNA is a cooking book, genes are recipes, and proteins the dishes resulting from processing the recipe ingredients.

The relationship between protein, amino acids, and DNA is defined by the DNA codes for proteins. Proteins are made up of amino acids.As DNA codes for proteins.

DNA, RNA, and protein are all intently related. DNA carries the records vital for encoding proteins, even though it does now no longer produce proteins directly. RNA includes the records from the DNA and transforms that records into proteins that carry out maximum cell functions.

What is DNA function?

The essential process of DNA is to make the proteins that residing matters want to grow.

In animals sexual reproduction requires

Answers

Answer:

The placement of sperm within female's reproductive track.

Explanation:

In animals, sexual reproduction requires sperm of male has to be placed in the reproductive track of female where eggs are present. The sperm of male fuse with eggs of female produces zygote which turns into an offspring. The sperm of male and egg of female are haploid in nature means having half number of chromosomes but when they fused together then the zygote which is formed is diploid i.e. double number of chromosomes. The gametes are formed through meiosis not mitosis. Mitosis cell division occur in body cells.

The diagram below shows a stack of rock layers. These layers have not changed position since they formed. Examine the diagram and answer the question that follows. If the age of Layer 4 is 400 million years and the age of Layer 1 is 500 million years, then the age of Layer 3 is A. older than 500 million years. B. between 400 million and 500 million years. C. 500 million years. D. younger than 400 million years.

Answers

The answer is B because if 4 is 400 million and 1 is 500 million it cannot go passed 500 million

The age of layer 3 will be between 400 million and 500 million years. Therefore, option (B) is correct.

Why rock dating is important?

Finding estimates of the ages of rocks is essential for identifying the speeds of geological processes as well as the history of geological occurrences. Some rocks may be used to determine the relative sequence of events. The most well-known methods are uranium-lead dating, potassium-argon dating, and radiocarbon dating.

Radiometric dating, which considers the ratio of two distinct isotopes in a sample, establishes the age of rocks. Geologists may use tools like these to assess the age of a material since radioactive isotopes degrade over a predictable period of time. mass spectrometer for thermal ionisation
