Answer: d. single-stranded binding proteins

Explanation:

DNA replication is the process through which DNA produces multiple copies of itself with the help of several enzymes or proteins.

Single-stranded DNA-binding protein (SSB) is one of the key protein resposnible for DNA replication. SSB binds to seperated ends of DNA and prevent the unwinded strands to get winded again which further allows enzymes to bind to a single-stranded DNA and proceed the replication process.

Due to the mutation of Single-stranded DNA-binding protein (SSB), the DNA  is able to separate with the help of helicase enzyme but the template strands come back together before replication.

Hence, the correct option is d. "single-stranded binding proteins".

Rock layers can be correlated to eachother using fossils.   Please select the best answer from the choices provided T F
viktelen [127]

The correct answer is - False.

To trace the correlation between the rock layers by using fossils can be a big mistake, though occasionally it may provide the proper information, still it will be relying on luck.

The case is actually the other way around, the fossils can be correlated by using the rock layers, because each layer of rocks represents some time in the geologic past.

The fossils, on the other hand, are much more easy to be moved through the layers over time, because there can be disturbances, adjustments in the crust, or the rocks can change their composition under the influence of multiple factors. All of that can contribute to the fossils ending up at places where they aren't expected to be, so using them to correlate the rock layers will not be a very useful method.

Use the balanced equation of a nitrogen cycle pathway below to support the conservation of matter and energy.
nadezda [96]
<h3><u>Answer and explanation</u>;</h3>
  • <u>According to the Law of conservation of mass; Mass cannot be created or destroyed in a chemical reaction.</u> The law of conservation of mass states that the total mass of substances taking part in a chemical reaction is conserved during the reaction. <u><em>For example in the equation;</em></u>
  • <u><em>N2 + 8 H --> 2 NH3 + H2</em></u>
  • <u><em>The number of hydrogen atoms and nitrogen atoms in the reactant side is equal to those on the product side.</em></u>
  • Additionally; <em><u>the law of conservation of energy states that the total energy of an isolated system remains constant, that is it can not be created or destroyed, rather, it can only be transformed or transferred from one form to another.</u></em>
