Answer:
Receptors are proteins or glycoprotein that bind signaling molecules known as first messengers, or ligands.
The primary function of DNA is to?
Answer:
The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code.
Explanation:
A in Biology class last year.
DNA is the genetic material of many organisms. The primary function of DNA is to store the genetic information that results in protein synthesis.
What is DNA?DNA or deoxyribonucleic acid is the nucleic acid that includes the instruction and the information that codes for protein synthesis. It is a crucial part of hereditary that passes the genetic traits from one generation to another.
The major role that it plays in an organism is to store the genetic code and information so that it can be used to synthesize proteins through the process of transcription and translation.
Therefore, DNA stores genetic information.

These are just the answer key. You will have to fill in the lower half of the questions yourself. I did not consider 32% and 1.6% approximately the same but the answer key did.
Hope this helps:)
Explanation:
The box’s measurements are: length = 50 cm, width = 25 cm, and height = 25 cm. The measurements of the block are: length = 10 cm, width = 10 cm, and height is 5 cm.
Out of 100 marble drops or shots, the marble hit the block 32 times.
volume of the box = 50 × 25 × 25 = 31250 cm 3
volume of the block = 10 × 10 × 5 = 500 cm 3
Ratio = 500/31250 = 0.016 × 100 = 1.6%
The volume of the block is 1.6% of the volume of the box
Ratio = 32 hits/100 shots = 0.32 × 100 = 32%
The block was hit 32% of the time.
Percentages will be similar and both be small percentages

Even though scorpions are related to spiders, there are many differences between the two organisms. One difference is that scorpion young do not hatch from eggs as spiders do. Scorpions are born live, two at a time, and they immediately crawl onto the mother's back for protection and care. They remain there for 2 weeks as they grow big enough to take care of themselves.
The skin cells of a scorpion organize together to make a hard covering called a carapace, which helps protect the scorpion. What is the term for a group of similar cells working together?
Question 11 options:
system
organism
organ
tissue
The skin cells of a scorpion organize together to form a hard covering called a carapace, which helps protect the scorpion. "Tissue" is the term for a group of similar cells working together. The last option is the correct answer.
What is a tissue?In a single-celled organism, cells perform all of the body's functions, whereas in multicellular animals, cells join together to form tissue, tissue joins together to form organs, and organs join together to form organ systems, and all functions are divided. By the time zygote formation occurs, there is only one cell present, and that cell has been divided, specialized, and assigned specific functions.
Some cells make stem cells, some make epithelial cells, and so on. The tissue is a group of cells having a similar function, such as epithelial tissue, which has many cells but all of them perform the same function, that of a skin cell; all of them have sweat glands, etc.
Hence, "tissue" is the term for a group of similar cells working together. The last option is the correct answer.

Answer:
The second portion of the nucleotide is the sugar. Regardless of the nucleotide, the sugar is always the same. The difference is between DNA and RNA.
Explanation:
thanks me and follow me
Five-carbon sugar (deoxyribose sugar) and phosphate moiety are the two parts of a nucleotide which do not change throughout the structure of DNA.
What are Nucleotides?Nucleotides are the organic molecules which are consisting of a nucleoside molecule and a phosphate moiety. They serve as the monomeric units of the nucleic acid polymers- deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are the essential biomolecules within all the different life-forms on the Earth.
Nucleosides are made up of nitrogenous bases and pentose sugar. There are changes at the nitrogenous bases in the different nucleoside molecules however, there are no changes in the pentose sugar and the phosphate moiety of the molecule.

Oceanic plate
Explanation:
The oceanic plate is the thinner but denser plate. At a convergent margin, this plate is known to subduct under the lighter continental plate.
Oceanic plates have an average thickness of about 6km. They are rich in ferromagnessian minerals. These minerals are much denser than those of the silicates that make up the continental plate.
Oceanic plates produce volcanic rocks especially basalts when they melt. They have a density of 3.0g/cm³ whereas continental plates have a density of 2.7g/cm³Give two names for a hydrogen atom with a missing electron
