The processing that takes place before a mature mRNA exits the nucleus,
A translation stop codon is introduced to the pre-mRNA's 3' end.
c. The 3' end of the pre-mRNA gets a poly-A tail (50–250 adenine nucleotides) attached to it.
d. Ribosomes splice out coding segments referred to as exons.
In eukaryotes, RNA must leave the nucleus through the nuclear membrane's pores and reach the cytoplasm to undergo translation during protein synthesis. The 3' Poly-A tail, 5' capping, and pre-mRNA splicing are the mRNA's departure mechanisms.The 5'capping procedure involves adding a 7-methylguanosine cap through phosphate linkage to the 5' end of the mRNA. This procedure helps to start translation processes and prevents mRNA degradation.The cleaving of pre-mRNA and attachment of about 200 A nucleotides, or the 3'poly (A) tail, to the mRNA by the poly (A) polymerase enzyme protein complex is known as the 3' Poly-A tail step. This facilitates the transfer of mRNA to the cytoplasm, stops pre-mRNA degradation, and starts translation.

Part 1: Comprehension Questions
1. What are two things mentioned in the reading that can happen that might affect an ecosystem?
2. Define ecological succession.
3. What is primary succession?
4. Describe an example of primary succession.
5. What is a pioneer species?
6. How long might it take for an ecosystem to become balanced?
7. What happens when an ecosystem is in equilibrium?
8. Define climax community.
9. Name two things that can disrupt a community.
10. What is secondary succession?
Answer: 1. One community replacing another as a result of changing abiotic and biotic factors. Establishment of a community in an area of bare rock that does not have topsoil. Lava flow destroys an ecosystem and hardens into bare rock. 2. Ecological succession is the process that describes how the structure of a biological community (that is, an interacting group of various species in a desert, forest, grassland, marine environment, and so on) changes over time. 3.Primary succession, type of ecological succession (the evolution of a biological community's ecological structure) in which plants and animals first colonize a barren, lifeless habitat. 4. Primary succession occurs when new land is formed or bare rock is exposed, providing a habitat that can be colonized for the first time. For example, primary succession may take place following the eruption of volcanoes, such as those on the Big Island of Hawaii. As lava flows into the ocean, new rock is formed. 5. Pioneer species are hardy species which are the first to colonize barren environments or previously biodiverse steady-state ecosystems that have been disrupted, such as by fire. Some lichens grow on rocks without soil, so may be among the first of life forms, and break down the rocks into soil for plants. 6. THIRTY TO ONE HUNDRED YEARS . 7. Ecological balance has been defined by various online dictionaries as "a state of dynamic equilibrium within a community of organisms in which genetic, species and ecosystem diversity remain relatively stable, subject to gradual changes through natural succession." and "A stable balance in the numbers of each species . A healthy ecosystem is said to be in equilibrium, which is a relatively stable state that keeps population sizes within a sustainable range (not too many of a certain species alive or dead). ... Some bears will starve and fewer cubs will be able to prosper, leading to a smaller overall population the next year. 8.A climax community is the last stage in succession, a stage where an ecosystem reaches a stable state. It is a mature ecosystem. ... Climax communities are stable. 9. Disturbances such as fire or flood can disrupt a community. After a disturbance, new species of plants and animals might occupy the habitat. Over time, the species belonging to the climax community are likely to return. 10. Secondary succession, type of ecological succession (the evolution of a biological community's ecological structure) in which plants and animals recolonize a habitat after a major disturbance—such as a devastating flood, wildfire, landslide, lava flow, or human activity (e.g., farming or road or building construction)— ... brainliest? plzz

Which adaptation would most likely help a plant collect more energy for photosynthesis? A. Broad leaves B. Short stems C. Deep roots D. Large flowers SCIENCE
Holes also allow more sunlight to get through to the leaves below, which maximizes sun absorption and photosynthesis. Adaptation: During the heat of the day's sunlight, most plants open stomata (pores) in their leaves to take in carbon dioxide from the air for photosynthesis, while allowing some water to escape.

Ollie runs 40 meters in 5 seconds. How far could she run in 60 seconds?
Answer:
60 seconds would be 480 meters
Explanation:
we can find the answer by using the method of distribution, but first take the 60 seconds and divide by 5 seconds and we'll get 12 then multiply that by 40 meters to get 480 meters and since we divided 60 seconds by 5 the was how we figured out what to multiply the 40 meters to.
Healthy rain forest ecosystems provide ecosystem services, such as clean air, shade, food, and water. How might an increase in palm oil plantations affect humans who live nearby?
Answer:
Negatively affected.
Explanation:
Increase in palm oil plantations negatively affected humans who live in nearby area because this palm oil plantations is the cause of deforestation. Due to this palm oil plantations, deforestation occurs that leads to loss of habitat of many species as well as decrease in the area of forest which provides us clean air, shade, food, and water. The decrease in forest area also causes natural disaster such as floods in the region. Forests play a significant role in the prevention of floods in the region.
PLZ ASAP Coniferous trees flourish because they take the opposite approach of deciduous
trees, they grow (slow/ast) and die (young/old),
slow, old
fast, old
Slow young
Fast young
Answer: They grow slow and die old
Explanation: I just took a test with the same question and it said I was correct plus it is on this website https://untamedscience.com/biology/biomes/coniferous-forest-biome/
Coniferous trees flourish because they take the opposite approach to deciduous trees, they grow slowly and die old. Thus, the correct option for this question is A.
What are the characteristics of Coniferous trees?The characteristics of Coniferous trees are as follows:
They have leaves that are very thin in the shape of needles. These trees don't have flowers but produce cones. Due to this, they are called coniferous trees.These trees grow in areas that have snowfall. Hence these trees have needle-like leaves that do not allow the snow to rest on them.The approach and properties of coniferous trees are absolutely opposite to those of deciduous trees. This is because the environment of both conditions differs greatly.
When there are not enough nutrients present in the soil, coniferous trees generally flourish because they take the opposite approach with respect to deciduous trees. Due to this, they grow slowly and die old.
Therefore, coniferous trees flourish because they take the opposite approach to deciduous trees, they grow slowly and die old. Thus, the correct option for this question is A.

How might the effectiveness of nectar change if it had a bitter taste?
Answer:
Floral nectar is offered by plants to animals as a reward for pollination. While nectar is typically a clear liquid containing sugar and trace amounts of amino acids, colored nectar has evolved in several plant families. Here we explore the functional significance of the phenolic compounds that impart a dark brown color to the nectar of the South African succulent shrub Aloe vryheidensis. Flowers of this aloe are visited.

what is another term for regular reflection
Answer:
Specular reflection, or regular reflection, is the mirror-like reflection of waves, such as light, from a surface
Answer:
Explanation:
Specular reflection, or regular reflection, is the mirror-like reflection of waves, such as light, from a surface.
The law of reflection states that a reflected ray of light emerges from the reflecting surface at the same angle to the surface normal as the incident ray, but on the opposing side of the surface normal in the plane formed by the incident and reflected rays. This behavior was first described by Hero of Alexandria (AD c. 10–70).
Specular reflection may be contrasted with diffuse reflection, in which light is scattered away from the surface in a range of directions.
