Answer:

Viruses and bacteria have a very specific way of organizing their own genetic material inside themselves.

Explanation:

On viruses, this can vary a little bit, but most of them will have their genetic material not confinated in a nucleus, but so, spread along all of the cytoplasm. This can be because of very different reasons, and the bacteria have the same thing here, they too have their genetic material spread all across their cytoplasm.

Instead of that, eukaryotes have something that the scientists call the nucleus. This nucleus contains all the DNA a cell needs to produce the proteins for the body, but remember, the protein making process happens inside and out of the nucleus.

How do transitional fossils help explain the evolutionary steps that took place to produce modem organisms?

lesya [120]

Answer:

Transitional fossils show how a particular taxa accumulated adaptations to fit particular environments and/or ecological niches

Explanation:

Transitional fossils are fossilized remains of taxonomic groups/species that illustrate an evolutionary transition between a known version of a taxa/species and the current taxa/species. Transitional fossils are fundamental because they can be clearly differentiated from the ancestral group as well as of its derived descendant group. For example, there exist transitional fossils known as "mammal-like reptiles"(i.e., therapsids that gave rise to the true mammals), which are clearly different from current mammals.

Zigmanuir [339]

Answer:

Evidence of metamorphism can be indicated by <u>flat, horizontal</u> layers within the rock.

Explanation:

Metamorphic rocks refer to rocks that are modified with heat or pressure, which change their physical and chemical properties. The main reason behind this modification is the rearrangement of the mineral crystals, which occurs due to their response to the previously-mentioned properties of heat and pressure.

There could be different types of evidence of metamorphism. However, the main evidence can be indicated by the presence of <u>flat, horizontal</u> layers within the rock, also known as foliation, a process that occurs when the pressure squeezes the minerals, leading to a flat, horizontal layer. Then, scientists could analyze the composition of these layers to identify minerals or even fossils within it.

What does pH measure?

kogti [31]

Answer: Answer below

Explanation: pH is a measure of the acidity or alkalinity of a solution. What the pH scale measures is basically the concentration of hydrogen and hydroxyl atoms in a solution. So, the last option is the answer. Another thing to keep in mind is solutions with a pH under 7 are acidic, solutions with a pH of 7 are neutral, and solutions with a pH over 7 are alkaline or considered a base. I hope this helped! Good luck:)
