Select three events that occur as an unspecialized cell differentiates into a cell that helps transport water in plants.
Answer:
Explanation:
Differentiation dramatically changes a cell's size, shape, membrane potential, metabolic activity, and responsiveness to signals. These changes are largely due to highly controlled modifications in gene expression and are the study of epigenetics.
The three events that occur as an unspecialized cell differentiates into a cell that helps transport water in plants are as follows:
Formation of vascular bundles like xylem and phloem.Cells are adapted to perform the process of photosynthesis and transpiration.Cells of the plant tissue become more compact than usual. What is cell differentiation?Cell differentiation may be defined as the process during which young, immature (unspecialized) cells take on individual characteristics and reach their mature (specialized) form and function.
In order for a cell to differentiate into its specialized form and function, it need only to manipulate those genes (and thus those proteins) that will be expressed, and not those that will remain silent. The primary mechanism by which genes are turned “on” or “off” is through transcription factors.
Therefore, the three events that occur as an unspecialized cell differentiates into a cell that helps transport water in plants are well-described above.

What is a nucleotide?RNA is a nucleic acid that is composed of nucleotides. A nucleotide is composed of a sugar molecule, a phosphate group, and a nitrogenous base. RNA differs from DNA in its single-stranded structure, the presence of uracil instead of thymine, and the sugar molecule being ribose.
The sequence of bases determines the genetic information in RNA. The bases in RNA are adenine, cytosine, guanine, and uracil. The sequence UGGCUCGAA represents an RNA sequence of bases.
The sequence UGGCUCGAA transfers the genetic information from the DNA to ribosomes, where the sequence is translated by ribosomes into amino acids, which results in the formation of a specific protein with a unique function in the cell.
Therefore, the correct strand of RNA bases is UGGCUCGAA.

Brainliest, Please!How would the bonding of a purine with a purine alter the dna molecule
A purine interacting with another purine would be problematic for the structure of the DNA molecule.
One of the two categories of nitrogenous bases found in DNA is purines; the other are pyrimidines.
Adenine (A) and guanine (G) are examples of purines, and they invariably couple with thymine (T) and cytosine (C), which are complementary pyrimidine bases.
DNA molecule. In the DNA molecule, pairings of two purines, such as adenine and guanine or guanine and guanine, would result in a bulky structure that would not fit into the double helix properly. The hydrogen bonds between the two strands of DNA would be broken as a result, which might result in a break in the DNA strand and mutations.Purine-purine bonding is therefore not conceivable in a DNA molecule because DNA's structure is highly particular and meticulously controlled to ensure its stability and function. For DNA replication and transcription to work appropriately, which is crucial for the transmission of genetic information and maintenance of life, the right matching of purines with pyrimidines is required.learn more about purine here

The picture below shows flowers on a tomato plant.
Lacy wants to design an experiment that will show which part of a tomato flower grows into the tomato fruit. What measurement could she make to study how the fruit grows?
Lacy wants to design an experiment that will show ovary part of a tomato flower grows into the tomato fruit.
What is ovary for plant?The female reproductive organ present in flowering plants is the ovary. It is present in the flower's gynoecium. It is a portion of the pistil that holds the ovules and is located near the base of the sepals and petals. A single carpel or numerous carpels joined together can form the pistil.
Ovaries, as we know, are an essential component of the plant's female reproductive system. Well, the ovaries are where pollen is kept before developing into ovules and ultimately seeds. These seeds then germinate, causing the ovaries to grow and convert into fruits.
Even though the blooms are self-fertile, the pollen is nevertheless moved to the female half of the blossom by wind and the buzzing of bees' wings. The young tomato grows after fertilization, when the petals and stamens fall off.
So, Lacy will show ovary part of a tomato flower grows into the tomato fruit.

Why is earthquake prediction a challenge for scientists? In your answer, explain why scientists aren’t able to develop a warning system for earthquakes.
Answer:
We do not know how, and we do not expect to know how any time in the foreseeable future. USGS scientists can only calculate the probability that a significant earthquake will occur (shown on our hazard mapping) in a specific area within a certain number of years.
Answer:
Earthquake prediction is a challenge for scientists because of the complex and variable nature of earthquakes. They can be caused by a number of factors, including tectonic plate movement, volcanic activity, and changes in the Earth's crust. These factors can interact in complex ways that make it difficult for scientists to develop a warning system for earthquakes.
Earthquakes can even occur without any warning signs, making them difficult to predict. Although scientists are able to identify potential earthquake hazards, they cannot always predict when or where an earthquake will occur, making it tough to develop an effective warning system.
Scientists are constantly working to improve our understanding of earthquakes and how to predict them. However, the challenge remains due to the complex and ever-changing nature of earthquakes.

What is the number of ATP produced from 5 molecules of glucose going through glycolysis?
Five molecules of glucose produces 20 molecules of ATP and consumes 10 molecules of ATP during the process of glycolysis.
What is Glycolysis?
Glycolysis is the process during which glucose molecule is broken down into simpler products to produce energy. It produces two molecules of pyruvate with ATP, NADH and water molecules. The process takes place in the cytoplasm of the cell and it does not require oxygen molecules. It occurs in both the aerobic and anaerobic organisms.
One molecule of glucose yields four molecules of ATP in total during one cycle of glycolysis. Since, 2 ATP molecules are used up in the first phase of glycolysis, there is a net gain of two molecules of ATP.
Therefore, for 5 molecules of glucose, there will be production of 20 molecules of ATP and consumption of 10 molecules of ATP.

A. Cells in the nose and mouth filter air breathed into the lungs.
B. Cells in the brain produce signals that control the movement of the eyes.
C. Cells in the mouth, stomach, and small intestine chemically break down food.
D. Cells in the walls of the heart and blood vessels allow blood to pass throughout the body.
The statement that can be used as evidence to support the group's claim is that cells in the brain produce signals that control the movement of the eyes. So the correct option is B.
Why is the statement correct?The statement is correct since we are talking about systems in the body being connected to maintain the body. The example of signals being sent through neurons to the eye muscles for eye movement to take place is a good example of the interconnection between two systems to maintain the body.
The connection between different areas of the body is important in a good functioning of the body, since the systems by themselves could not monopolize all the functions. The nervous, bone, and muscular systems, among others that we have, are connected in one way or another to be able to function as a whole.
Therefore, we can confirm that the correct option is B. Cells in the brain produce signals that control the movement of the eyes.

If the sequence 3' TCGTA 5' was used as a template in DNA replication, what would be the sequence of bases on the newly synthesized strand?
Answer: Sequence will be AGCAT.
Explanation:
DNA replication, as used in molecular biology, is the biological process that creates two identical copies of DNA from a single original DNA molecule. Its mechanism is different in eukaryotes and prokaryotes.
The DNA sequence that is duplicated when mRNA is produced is referred to as a template strand. It refers to the strand that is utilized by the enzymes responsible for DNA replication or RNA transcription to attach complementary nucleotides.
DNA polymerases, which require a template and a primer (beginning) and synthesis DNA in the 5' to 3' orientation, are the enzymes responsible for creating new DNA. One new strand (the leading strand) is created during DNA replication in one continuous piece. Small fragments make up the other (lagging strand).
