WHAT store energy for an organism and help to make up the structure of the cell membrane.

Answer:

A and F are phosphate groups.

B and E are sugars.

C and D are nitrogenous bases.

Explanation:

Nucleotides are the molecules responsible for composing DNA and RNA. They are formed by three units: a phosphate group, a sugar molecule and a nitrogenous base.

The sugar molecule is a pentose, which means that it is a molecule formed by 5 carbons. These collections are represented by geometrical figures such as the letters "B" and "E" shown in the figure above, where each tip represents a carbon.

The nitrogenous bases are molecules that are named adenine (A) and guanine (G) and the pyrimidine bases cytosine (C), uracil (U) and thymine (T).

The phosphate group, in turn, is a molecule derived from phosphoric acid and is the only one that does not vary in each nucleotide.

Labels A and F correspond to phosphate groups, label B corresponds to a deoxyribose sugar, label E corresponds to a ribose sugar, and labels C and D correspond to nitrogenous bases.

In conclusion, labels A and F correspond to phosphate groups, label B corresponds to a deoxyribose sugar, label E corresponds to a ribose sugar, and labels C and D correspond to nitrogenous bases.

Answer:

Translation.

Explanation:

During translation, nucleotide sequence information is changed into amino acid sequence information.

The primase is a single-stranded RNA molecule that base-pairs with a DNA template and starts DNA synthesis .

The primase generates short strands of RNA that bind to the single-strande DNA to initiate DNA synthesis by the DNA polymerase. These sections are called Okazaki fragments, and they are short lengths of DNA.

Okazaki fragments are short sequences of DNA nucleotides (about 150 to 200 base pairs lengthy in eukaryotes) which can be synthesized discontinuously and later linked collectively via the enzyme DNA ligase to create the lagging strand in the course of DNA replication

Answer:

A: serine, tryptophan, serine, valine

Explanation:

Hi there!

Protein Synthesis is the process where proteins are created from DNA.

We are given the mRNA strand AGUUGGUCUGUA, as well as a provided chart

The mRNA strand is created out of nucleotides (each of the letters is one nucleotide in the code), which will code for a specific chain of amino acids, creating a protein.

Each amino acid is made up of 3 nucleotides. This sequence of 3 nucleotides is called a codon.

So we can break up the code into groups of 3, to make identifying the codons easier.

AGU UGG UCU GUA

Now we need to figure out which amino acid each codon codes for. Thankfully, we were given a chart that can help us with that.

The chart is read where the first base is on the left, and is vertical. The second base is in the center, yet is horizontal. The third base is on the right, and is also vertical.

Let's start with the first codon, which is AGU

The first base is A. The second base is G, and the third base is U. So the first amino acid is serine (ser)

The second codon is UGG.

The first base is U, the second base is G, and the third base is G. So the second amino acid is tryptophan (trp)

The third codon is UCU

The first base is U, the second base is C, and the third base is U. So the third amino acid is serine (ser)

The fourth codon is GUA

The first base is G, the second base is U, and the third base is A. So the fourth amino acid is valine (val).

That means the amino acid sequence from the mRNA code is: serine, tryptophan, serine, valine. The answer is A

Work-Rate Problems

There are two equivalent formulas to choose from when solving work-rate problems. If two people are working together on a job then their work rates add and they can perform the job working together in a shorter amount of time. If we let  = the time it takes a person to complete a task then his work rate is 1/. In other words, he can complete the 1 job in  number of hours. If we let  = the time it takes a second person to complete the task and  = the time it takes for both people working together we get the following work-rate formulas:

Example: Bill’s garden hose can fill the pool in 12 hours.  His neighbor has a hose that can fill the pool in 15 hours.  How long will it take to fill the pool using both hoses?

Example: Joe can complete his yard work in 3 hours by himself.  If his son helps it will only take 2 hours working together. How long would the yard work take if his son was working alone?

Example: Norm and Cliff can paint the office in 5 hours working together. Being a professional painter, Norm can paint twice as fast as Cliff. How long would it take Cliff to paint the office by himself?

Work-Rate Problem: One small water hose takes twice as long to fill the basin as the larger water hose. If the two hoses working together take 40 minutes to fill the basin how long would it have taken each hose to individually fill the basin?

Work-Rate Problem: Joe can texture and paint a room in 8 hours working alone. It would take Bill 6 hours to do the same job. How long will it take them to complete the job working together?

Work-Rate Problem: Two printers, working at the same rate, work together with printing payroll checks for 4 hours before one breaks down. The other takes 3 more hours to complete the job working alone. How long would it have taken only one printer to complete the job?

Uniform Motion Problems (Distance Problems)

We have set up uniform motion problems using the formula  =  *. For the following motion problems, we will need the equivalent formula / =  to set up the equations.

Example: The first leg of Mary’s road trip consisted of 120 miles of traffic.  When the traffic cleared, she was able to drive twice as fast for 300 miles. If the total trip took 9 hours, then for how much time was she stuck in traffic?

Example: A passenger train can travel 20 miles per hour faster than a freight train.  If the passenger train can cover 390 miles at the same time it takes the freight train to cover 270 miles, how fast is each train?

Example: Billy rode his skateboard 24 miles to his grandmother’s house for the day. It was a rough ride so he borrowed his grandmother’s bicycle for the return trip. Going twice as fast on the bicycle the return trip took 2 hours less time.  What was his average speed on the bicycle?

Example: Brett lives on the river 45 miles upstream from town.  When the current is 2 miles per hour he can row his boat downstream to town for supplies and back in 14 hours.  What is his average rowing speed in still water?

Telomeres are non-coding sequences on the ends of chromosomes. They contain a high concentration of guanosine .Tetraplexes other structure may be in telomeres. option d)

At the ends of linear chromosomes, a region of repeating nucleotide sequences known as a telomere is connected to specific proteins. A ubiquitous genetic trait called telomeres is most frequently observed in eukaryotes.

They ensure the integrity of linear chromosomes by preventing DNA repair systems from mistaking the very ends of the DNA strand for a double-strand break in the majority, if not all, of the species that possess them. They also protect the terminal regions of chromosomal DNA from progressive degradation.

Mobilizing deposits from the poor poses several challenges, including lack of documentation, limited financial literacy, inadequate access to banking services, informal financial practices, and mistrust in formal financial institutions.

Mobilizing deposits from the poor can be challenging due to various factors.

First, many individuals in impoverished communities may lack proper documentation such as identification cards or proof of address, which are often required by formal financial institutions to open accounts. This can hinder their ability to access banking services and deposit their savings.

Second, there is often limited financial literacy among the poor, making it difficult for them to understand the benefits and processes of depositing money in formal institutions.

Third, in many underserved areas, there is a lack of accessible banking services, with banks being located far away or having limited outreach programs, making it inconvenient for the poor to deposit their money.

Fourth, informal financial practices, such as savings groups or rotating savings and credit associations, may be prevalent in these communities, leading individuals to rely on these systems instead of formal banking channels.

Finally, there may be a general mistrust or skepticism towards formal financial institutions due to past experiences or perceptions of exclusion, making it challenging to encourage deposit mobilization among the poor. Overcoming these challenges requires innovative approaches, such as mobile banking solutions, financial education programs, and building trust through community engagement.

Answer:

The original species will diverge into two new species. It will occur speciation. It will occur some sort of allopatric speciation.

Explanation:  

When the original species is divided and placed under different environments, where they can reproduce for many generations, many changes or mutations will occur in each group. These changes will depend on each group´s environment and its ecological pressures and will lead to divergence. Pressures act on individuals and make them adapt to the new environmental conditions. Generation after generation, the genotype of individuals will increase the fitness to survive and reproduce. The fixation of mutations will increase the difference among both groups, up to the diverging point into two new species.

The biological concept of species states that individuals of the same species can reproduce because they have a genetic reservoir in common: many genetic variants.

Genetic variability is the measure of a species organism´s tendency to differentiate. In genetic variability, individuals of the same species are not identical. They are recognizable as members of the same species, but they differ in shape, function, and behavior. There exist variations among individuals of the same species.

Genetic variability originates from mutations, recombinations, and karyotype alterations. It allows or makes possible evolution.

Allopatric speciation consists of the geographic separation of a continuous genetic background giving place to two or more new geographically isolated populations. These separations might be due to migration, extinction of geographically intermediate populations, or geological events. In this speciation, some barriers impede genetic interchange, or genetic flux, as the two new populations that are separated can not get together and mate anymore. These barriers might be geographical or ecological.

The process of allopatric speciation involves different steps:

• The emergence of the barrier.

• Interruption in the genetic interchange

• The occurrence of new mutations and their accumulation in time in each population. Slow and gradual differentiation.

• Genetic divergence by natural selection and reproductive isolation makes it impossible for the two groups to mate even if the barrier disappears.

• Prezigotic isolation mechanisms favored by selection once occurs a secondary contact between the new species in formation.

A cell membrane, also known as a plasma membrane, is a thin, semipermeable barrier that surrounds the cytoplasm of a cell and separates the cell from its environment.

What do you mean by cytoplasm?

Cytoplasm is the fluid-like substance found in the interior of a cell, excluding the nucleus. It is composed primarily of water and contains a variety of organic and inorganic molecules, ions, and organelles. It functions as the cell’s metabolic center and plays important roles in many cell processes, such as energy production, protein synthesis, and cell division.

Five important key features of the cell membrane:

1. Phospholipid Bilayer:  The phospholipid bilayer is important for regulating the flow of substances both into and out of the cell, allowing the cell to acquire the nutrients it needs and expel waste.

2. Glycoproteins: They are important for cell-to-cell communication, as they bind to specific receptors on other cells to facilitate communication between the cells. They also act as recognition sites for hormones and other molecules that enter the cell.

3. Cholesterol: Cholesterol is a fatty molecule that helps stabilize the cell membrane and prevents it from becoming too rigid or too fluid. It also helps regulate the movement of substances across the cell membrane.

4. Integral Proteins: They are important for transporting molecules across the membrane, as well as for recognizing and interacting with other molecules.

5. Peripheral Proteins: They play an important role in cell signaling and regulation, as they can interact with other proteins or molecules on the cytoplasmic side of the cell membrane. They are also important for anchoring the membrane to the cytoskeleton.
