What are the three major steps involved in mRNA processing?
The three major steps in mRNA processing are capping, splicing and polyadenylation.
What is mRNA processing?The mRNA produced by the process of transcription of DNA is not functional and needs further processing. This mRNA is called precursor mRNA or pre mRNA.
The result of the processing is the production of mature mRNA which can be translated to form proteins.
mRNA modifications required to yield mature mRNA are 5' capping, splicing of introns, and 3' polyadenylation.
5' capping means the addition of a 7' methylguanosine cap (m7g) to the 5' end of the mRNA.
Introns are non-coding regions present in the precursor mRNA which need to be removed. These are removed by the process of mRNA splicing. The coding regions are called exons which are joined after the introns are removed. Exons can be translated into proteins.
At the 3' end of the pre mRNA, cleavage occurs and 250 adenine residues are added. This forms a polyadenylated tail at the 3' end of the mRNA.
Therefore the three major steps in mRNA processing are capping, splicing and polyadenylation.

I need extreme help!!1 I'm doing an essay in biology that is only 5 sentences long. I'll leave my teacher's example. The question is "How can science improve our lives?" (THIS IS THE EXAMPLE: “In today’s world, science can be used to improve the lives of many people. One example of how science can improve our lives is by allowing us to gain new knowledge and perspectives about how the world works. We can learn from our mistakes and build new ideas as we continue to research and learn more about the world around and inside of our bodies. Another example of how science can improve our lives is by providing new advancements in technology such as medicines and vaccines that help eliminate certain diseases. One final way that science can be used to improve our lives is by creating a universal language in the scientific method that we can all contribute to in our own ways. In conclusion, learning about science can benefit us as individuals and as a society by making our lives better in a number of ways- it helps us see new perspectives, make advances in technology and medicine, and creates a universal method for how we interpret the world.")

Energy and Matter Energy cannot be created or destroyed. Explain how energy is conserved in cellular respiration. Include in your explanation how energy is transferred and converted at the levels of a single cell and of an organism.
Answer:
In the organism matter and energy also follows the law of conversion which means energy or matter can not be created or destroyed, it just changes its form in any system.
Cellular respiration is a catabolic reaction that converts chemical energy in the form of the energy that is used by the cell by breaking the complex sugar and other macromolecules into simple and smaller components and release waste products with the energy in ATP (a useable form of energy for the cell).
The energy stored in the bonds of the sugar and other organic molecules take place in this process converted into the chemical bond formed in ATP, is exactly the same only changed its form.

Why are plants and animals able to survive in the tundra?
The Arctic and the summits of mountains are home to tundra ecosystems, which are characterized by their lack of trees and harsh climates with little rainfall.
What is tundra region?Snow covers tundra lands for the majority of the year, but summer provides bursts of wildflowers.
The small plants of the tundra employ dormant strategies, producing seeds only occasionally, turning with the sun to absorb energy, and growing protective coverings.
The ability to build subterranean insulated tunnels as well as heavy winter coats, seasonal color-changing camouflage, and efficient body shapes have all been developed by animals that live in the Arctic tundra.
Therefore, The Arctic and the summits of mountains are home to tundra ecosystems, which are characterized by their lack of trees and harsh climates with little rainfall.

https://brainly.com/question/2018762
#SPJ6
Answer: Plants and animals are able to survive in the tundra because they have adaptations that allow them to thrive in the harsh conditions of the Arctic and sub-Arctic regions. These adaptations include thick fur or feathers to insulate against the cold, small body size to minimize heat loss, and the ability to store food and nutrients during the short growing season. Additionally, many tundra plants have shallow roots that can absorb nutrients quickly when they are available, and some have developed the ability to photosynthesize at low temperatures and with minimal sunlight.
To help explain surface tension, use a single water molecule in the template, and draw arrows representing the possible locations of hydrogen bonds formed by the molecule. The possible hydrogen bonds formed by a water molecule below the surface are shown.
Answer:
The correct representation is attached with the explanation.
Explanation:
In this representation of the surface tension, blue arrows between green water molecules are the possible molecules that can be used as the location for forming hydrogen bonds by a single molecule. Surface tension is the tendency of a liquid surface strectch to neighbouring molecules or ability to shrink in minimum surface area possible. Hydrogen bonds is an intermolecular force or interaction responsible for the surface are of liquide molecules. This bonds is towards every direction where the similar molecule present.
When sodium ions enter a neuron through chemically gated channels, they always cause depolarization, and thus firing of the cell. The same effect occurs when we contract skeletal muscle cells because they also contain
Answer:
Calcium ions
Explanation:
This is because the contraction of skeletal muscle occurs as a result of the release of Calcium ions from internal stores which is a result of the function of a neural signal.
So, skeletal muscles contract when calcium ions are released. There is also an action potential which is generated which causes the muscle to contract. This action potential is present in both skeletal muscle cells and neurons and is as a result of the movement of sodium ions in neurons and calcium ions in skeletal muscle cells.
Which process of evolution would best explain why closely neighboring sites have very similar beetle populations
Answer:
Gene flow
Explanation:
Gene flow can be defined as the transfer of genes from one population to another, which may be due to the migration of individuals that reproduce in the new population or due to gamete dispersal (for example, pollen dispersal in plants). Gene flow is a very important mechanism capable of changing allele frequencies in populations. Gene flow is low in species with low dispersal ability and has a huge effect in populations with small sizes. Moreover, high rates of migration among nearby populations are expected to increase their genetic homogeneity (thereby constraining speciation processes).

Water has a pH of 7. If you add and acid to this water, how would it affect the pH?
)
A)
pH would increase
B)
pH would decrease
pH would not change
D)
All of The Above
Answer:
pH would decrease in this case
Explanation:
Adding water to an acid or base will change its pH. Water is mostly water molecules so adding water to an acid or base reduces the concentration of ions in the solution. When an acidic solution is diluted with water the concentration of H + ions decreases and the pH of the solution increases towards 7.

Bottom-oriented fish have large, broad pectoral fins and depressed( flattened top-to-bottom) body shapes. Explain how these adaptations are well suited for life at the bottom of a body of water.
Answer:
they are better for camoflauge and for deep pressure
Explanation:
the fins helps control the crushing pressure that is constant at deep depths and the flattened bodies make them less visible since it is dark
Bottom-oriented fish have large, broad pectoral fins and depressed (flattened top-to-bottom) body shapes.These adaptations are well suited for life at the bottom of a body of water.
What is adaptation?Adaptation refers to the process where organisms inherit traits that help for better survival and reproduction in its environment.The large, broad pectoral fins and depressed body shapes of bottom-oriented fish are well-suited for life at the bottom of a body of water for several reasons:
The broad pectoral fins provide the fish with greater surface area, which allows them to maintain their position and stability while resting on the bottom of the water body The depressed body shape of these fish allows them to minimize their profile and reduce their exposure to the water current.Hence, the large, broad pectoral fins and depressed body shapes of bottom-oriented fish are adaptations that help them to survive and thrive in the challenging conditions of the bottom of a body of water.

Why we should care that greenhouse gases have been increasing? (2-3 sentences at least please).
Answer:
We should care about greenhouse gasses becasue, to much of it is causeing global warming. Which causes glaciers/polar ice caps and ice to melt. Greenhouse gasses also cause things like hurricanes, cyclones, typhoons. And sooner or later the ozone layer will break more and will allow radiation to come and heat up the planet more, and can disrupt the atalntic current and then could cause superstorms to start a new ice age. This is why we should care

Answer:
B. The nucleus is responsible for housing the genetic information needed for cell division.
Explanation:
I am pretty sure it is B from the information I found.
- The nucleus is a highly specialized organelle that serves as the information and administrative center of the cell. This organelle has two major functions. It stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include intermediary metabolism, growth, protein synthesis, and reproduction (cell division). -
1. What differences can you see when you compare the nucleus of a dividing cell with that of a non-dividing cell? 2. If your observation had not been restricted to the tip of the onion root, how would the results be different?
Answer:
It will be observed that in the cell that undergoes the division there is a constriction of the membrane and part of the cytosol, with its chromatic poles at the ends and even possibly double genetic load in the center.
Explanation:
In general, these cells are seen with eosin and hematoxycillin, with which, their internal media will be more basophilic, with more violet staining since they have a high protein load in their interior due to the great genetic load.
During cell division, the genetic load increases because the amount of material is doubled to give a daughter cell.
