Scientists can determine relatedness amongst organisms via way of means of evaluating partial amino acid sequences. The desk suggests 4 partial amino acid sequences from 4 organisms.
<h3>What is determine relatedness?</h3>
Presently, the maximum customary technique for building phylogenetic timber is a technique referred to as cladistics. This technique kinds organisms into clades, organizations of organisms which are maximum intently associated with every different and the ancestor from which they descended.
Scientists can now decide relatedness via way of means of evaluating the frequency of nucleic acid bases (the G + C content), carry out nucleic acid hybridization to decide the diploma to which DNA sequences are the same, carry out nucleic acid sequencing, or carry out different superior molecular techniques.

<h3><u>Answer and explanation;</u></h3>
- Density plays an important role in the study of Earth. It affects Earth's climate, plate tectonics, and subduction.
- <em><u>Subduction occurs at the convergent plate boundaries. Density plays a major role for subduction to take place. Subduction is driven by the excess density of the lithosphere compared to the underlying asthenosphere.</u></em>
- <em><u>Oceanic plates are denser and colder than continental plates, because the ocean cools them. Subduction can occur between an oceanic plate and a continental plate, or two oceanic plate or two continenetal plates.</u></em>
- During subduction between oceanic and continental plates, mantle convection drags the denser oceanic plate downwards and forces it down into the asthenosphere.
- During subduction between two oceanic plates, mantle convection drags the older, denser oceanic plate downwards and forces it into the asthenosphere.
- During subduction between two continental plates, there is no mantle convection, because the two plates are of similar densities.
Five types of pathogens r viruses, bacteria, fungi, protozoa, and worms.
water contaminated with germs can often be made safe to drink by boiling, adding disinfectants, or filtering
Answer:
They form when sediment accumulates.
Explanation:
Sediment is deposited out of air, wind, gravity; sediment is formed when weathering and erosion break down a rock into loose source material in a source area.
<u>Answer</u>: B. complex, folded chains of amino acid
Proteins are a class of large organic compounds composed of amino acids in the form of one or more long chains. The amino acid sequence determines the protein's shape and is in turn dictated by the DNA sequence that codes it. Proteins are vital for all the body's functions.
