What is RNA and what does it do?

Biology
1 answer:
bagirrra123 [75]3 years ago
5 0
<span> RNA was thought of as little more than a messenger between DNA and proteins, carrying instructions as messenger RNA (mRNA) to build proteins. However, RNA can do far more. It can drive chemical reactions, like proteins, and carries genetic information, like DNA. And because RNA can do both these jobs, most scientists think life as we know it began in an RNA world, without DNA and proteins.</span>

How do latitude and altitude affect which plants grow in an area?
vladimir2022 [97]
<span>They are both important. Latitude, the lines that parallel the equator are very important in determining plant growth rates and which plants can even exist because latitude is strongly related to average temperature. Altitude acts like latitude only over a shorter scale, so an increase in altitude of 1,000 ft may act like a latitude change of 3-4 degrees pole-ward. Longitude, that series of lines, perpendicular to the equator is also important, and is more related to water supply in the form of precipitation, so it would surely influence the kind of plants present - like desert plants versus rain forest types. Environments that are warm and with more rainfall generally will support more plant growth than those that are cold with little rainfall.</span>

Which correctly lists the three zones that further divide the open-ocean zone?
Serga [27]

Answer:

Deep zone, surface zone and transition zone.

Explanation:

Open sea zone is the area of the coastal areas above the sea bed and cover the continental shelf where large Marine organism are present and there is enough sunlight algae organism use to photosynthesize and produce food for the Marine organisms by converting carbondioxide and water into carbohydrates.

The zone stretches from the surface , to the middle and depth of 200 m.

The surface zone is the area where light penetrates most , the transition stretches from the surface zone downward, in this zone light penetrates bit not as much as surface zone and in the deep zone, it stretches from the transition zone downward to a depth of 200 meters and don't have enough light penetration compare to surface and transition.

What question would you ask to identify the limiting factors that are affecting the monarch population
max2010maxim [7]

Answer:

The correct answer is - "is this factor decreasing the population growth rate in the environment?".

Explanation:

When a factor or resource in the environment causes the decreases or lowers the population growth rate, such factors known as the limiting factors. Limiting factors can be lower food resources, higher competition, lower birth rates, higher death rates, and many other factors.

Thus, the correct question should ask about the limiting factors that are affecting the monarch population would be - "is this factor decreasing the population growth rate in the environment?".

The emergence, growth, and extinction of a large clade, such as the dinosaurs, is an example of a Choose... pattern. This patter
damaskus [11]

Answer:

macroevolutionary; background; mass

Explanation:

Macroevolution is defined as the evolutionary process of higher taxa (above the species level). Macroevolutionary patterns include stasis (lack of evolutionary change over a long period), speciation (diversification), lineage character change (modification of major features/traits), and extinction (termination of a species or taxon). Moreover, background extinction refers to the extinction of individual taxon/species due to environmental factors (e.g., climate change, disease, habitat loss, competition, etc), which account for the majority of all extinctions. Conversely, mass extinction refers to the time period in which a major proportion of all known species (about three-quarters or even more of all species) living at the time goes extinct.
