Dna is a polymer consisting of repeating units known as Necleotides.
Answer:
The answer is the first option.
Explanation:
Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.
Answer:
Right pulmonary artery
Explanation:
Based on the scenario being described within the question it can be said that the structure being described is known as the Right pulmonary artery. This is the longer and also the larger of the two arteries that conveys venous blood from the heart to the lungs. This artery is roughly 3 cm in diameter and 5 cm in length, and it's main function is delivering oxygen-depleted blood to it's corresponding lung.
They posses the following traits: vertebrae, bony skeleton, four limbs, and amniotic eggs
Phylogenetic trees present common traits to animals in similar phylums.
These trees characterize traits by having the animal ABOVE the trait. Take these few examples from here: primates and rodents and rabbits are the ONLY ones with hair and crocodiles and birds are the ONLY ones with eggs with shells.
Now that you know this, look at the 4 types of animals that must have the similar traits. Look for the characteristics that are below them. They are all above the following: vertebrae, bony skeleton, four limbs, and amniotic eggs. These are the traits that all the organisms similarly have.
For a better understanding, any animals BELOW the traits do NOT have the traits, take for example that sharks and ray-finned fish are below four limbs, meaning they don’t not possess this trait.
Answer:
Ribosomes consist of two major components: the small and large ribosomal subunits. Each subunit consists of one or more ribosomal RNA (rRNA) molecules and many ribosomal proteins (RPs or r-proteins). The ribosomes and associated molecules are also known as the translational apparatus.
