what system creates red blood cells

Answer:

Natural pollinators, like bees, pollinate flowers randomly, essentially mixing up their genomes and increasing genetic diversity. This leads to different types of future plants. However, artificial pollination is so labor intensive, it's hard to replicate the same variety in pollination.Aug 8, 2017

Explanation:

Artificial pollination is the type of pollination carried out by humans. It is a mechanical technique used to pollinate plants when natural pollination is insufficient or undesirable. It does not require the help of insects or weather.

Natural pollination consists of the transfer of pollen between the male and female organs of the flowers, without human intervention. In other words, pollen is transferred from the stamens to the stigma of the flowers, where it fertilises the ovules, making seed and fruit production possible.

To determine the mRNA strand and the resulting amino acid chain during protein synthesis, we need to transcribe the given DNA sequence into mRNA and then translate it into amino acids using the genetic code. These are fundamental steps that both occur during synthesis of protein.

Given the DNA sequence: AAA-GCT-CCA-TCG-GCT-AGG

1. Transcription:

During transcription, DNA is converted into mRNA. We create the complementary mRNA sequence by replacing each DNA base with its corresponding RNA base:

AAA-GCT-CCA-TCG-GCT-AGG (DNA)

UUU-CGA-GGU-AGC-CGA-UCC (mRNA)

2. Translation:

During translation, mRNA is decoded to produce an amino acid chain based on the genetic code. Each set of three mRNA bases, called a codon, corresponds to a specific amino acid. Here's how the mRNA sequence is translated into amino acids using the genetic code:

UUU | CGA | GGU | AGC | CGA | UCC (mRNA)

Phenylalanine-Arginine-Glycine-Serine-Arginine-Serine (we must look at a codon table to interpret what amino acids are corresponding)

Answer:

Therefore, the mRNA strand produced from the given DNA sequence is UUU-CGA-GGU-AGC-CGA-UCC, and the resulting amino acid chain during protein synthesis is Phenylalanine-Arginine-Glycine-Serine-Arginine-Serine.

Explanation:

The RNA world hypothesis is a scientific hypothesis that proposes that life on Earth may have first originated from self-replicating RNA molecules, before the evolution of modern DNA-based life.

A major feature of the RNA world hypothesis is the idea that RNA molecules were capable of both storing genetic information and catalyzing chemical reactions.

This is because RNA is able to fold into complex three-dimensional structures, which can function as enzymes (called ribozymes) and catalyze chemical reactions in a way that is similar to the role of proteins in modern life.

According to the RNA world hypothesis, these self-replicating RNA molecules could have gradually evolved over time, becoming more complex and eventually leading to the formation of the first cells.

While the RNA world hypothesis is still an active area of research and debate, it provides a compelling explanation for how the first life on Earth may have arisen.

After the transformation experiment, the plates that should be transformed are b) LB/amp-DNA and c) LB/amp+DNA.

This is because the transformation experiment involves the transfer of DNA into a host cell, and these plates contain the necessary components for the transformed cells to grow and be selected for.

The LB/amp-DNA plate contains both the LB broth, which provides nutrients for the cells, and the antibiotic ampicillin, which will select for cells that have taken up the DNA and are resistant to the antibiotic.

The LB/amp+DNA plate also contains these components, as well as additional DNA that can be taken up by the cells.

The LB-DNA and LB/amp/ara+DNA plates do not contain the necessary components for the transformed cells to grow and be selected for, and therefore should not be used in the transformation experiment.

Here is your answer!!

Thank you!!

Carbaminohemoglobin differs from hemoglobin in that it is a compound formed by the binding of carbon dioxide (CO2) to the amino groups of hemoglobin. Hemoglobin is the protein responsible for transporting oxygen (O2) in the blood, while carbaminohemoglobin is involved in the transport of carbon dioxide.

When carbon dioxide is produced as a waste product in tissues, it diffuses into the bloodstream and combines with hemoglobin within red blood cells. The carbon dioxide molecules bind to the globin part of the hemoglobin protein, specifically to the amino groups of certain amino acids, forming carbaminohemoglobin. This binding occurs in a reversible manner, allowing the release of carbon dioxide at the lungs for elimination during exhalation.The presence of carbaminohemoglobin helps facilitate the transport of carbon dioxide from tissues to the lungs, where it can be removed from the body. This mechanism plays a vital role in maintaining the acid-base balance in the blood and regulating the respiratory system.In summary, carbaminohemoglobin differs from hemoglobin in that it is a complex formed by the binding of carbon dioxide to specific amino groups of the hemoglobin protein, enabling the transport of carbon dioxide in the blood.

Dr. Ward mentioned that scientists started developing mRNA vaccines about 30 years ago. Unlike traditional vaccines, which use weakened or inactivated viruses, mRNA vaccines teach our cells to make a piece of the spike protein that triggers an immune response.                                                                                                                                                            

Pfizer and Moderna's COVID-19 vaccines use this technology to provide protection against the virus. The mRNA approach has proven to be a successful and safe method for creating vaccines, as seen with the high efficacy rates of the COVID-19 vaccines.
Both Pfizer and Moderna's SARS-CoV-2 vaccines utilize mRNA technology to express the spike protein, which is different from traditional flu vaccines that often use attenuated versions of the influenza virus. This innovative approach has enabled rapid development and deployment of effective vaccines against COVID-19, showcasing the potential of mRNA-based strategies in combating infectious diseases.

The selection index based on own performance is a useful tool for evaluating the potential response to selection for multiple traits.

A) A selection index is a technique used in animal breeding to identify the best breeding animals based on a selection of traits. This index is used to estimate the breeding value of an animal in a breeding program.

B) Economic values are used to assign relative economic importance to different traits in a breeding program. The predicted response, on the other hand, is the expected improvement in a trait due to selection for that trait. It is calculated by multiplying the selection differential by the heritability.

C) The economic weights are appropriate for the breeder’s goal since they reflect the breeder’s desire to increase weight while decreasing feed intake. A positive response for feed intake may be due to the genetic correlation between the two traits. Since the genetic correlation between weight and feed intake is positive, selection for weight will indirectly lead to an increase in feed intake.

D) To design an index such that there was no response for feed intake, the index would need to be designed so that it only selects animals based on their weight and not their feed intake. This would involve assigning a weight of zero to feed intake in the selection index. This would mean that only animals with the highest weight would be selected, regardless of their feed intake.

However, the economic weights used in the index should be appropriate for the breeder’s goal in order to maximize the desired response. In this case, the positive response for weight suggests that the economic weights used are appropriate, but the negative response for feed intake suggests that a different design may be necessary to achieve the breeder’s goal of increasing weight while reducing feed intake.

In order to preserve a healthy skin microbiome, regular soap would be the best choice compared to antibacterial soap or hand sanitizer that kills 99% of bacteria.

Here's why:

Regular soap is designed to effectively remove dirt, sweat, and oil from the skin without killing the good bacteria that lives on the skin’s surface.

In contrast, antibacterial soaps and hand sanitizers are formulated to kill bacteria on the skin.

While this can help prevent the spread of harmful bacteria, it can also kill the beneficial bacteria that protect the skin.

Regular use of antibacterial soaps and hand sanitizers can lead to an imbalance in the skin’s microbiome, which can make it more difficult for the skin to fight off infections.

Regular soap, on the other hand, is a milder and less harsh option that simply cleanses the skin without damaging the skin’s natural microbiome.

It is important to note, however, that not all regular soaps are created equal.

Some contain harsh ingredients that can still damage the skin.

For best results, it is important to choose a mild, fragrance-free soap that is gentle on the skin.

Additionally, moisturizing the skin after washing can help maintain a healthy skin microbiome.

The molecule that directly donates a nitrogen atom for the formation of urea during the urea cycle is arginine.

Here's a step-by-step explanation of the process:

1. In the urea cycle, the first nitrogen atom is contributed by ammonia, which reacts with bicarbonate to form carbamoyl phosphate.
2. Carbamoyl phosphate then reacts with ornithine to form citrulline.
3. Citrulline combines with aspartate, which also donates a nitrogen atom, to form argininosuccinate.
4. Argininosuccinate is cleaved into fumarate and arginine.
5. Finally, arginine directly donates its nitrogen atom for the formation of urea, with ornithine being released as a byproduct.

Thus, arginine is the molecule that directly donates a nitrogen atom for urea formation in the urea cycle.

Earth-based optical telescopes work best at night because they rely on visible light from distant objects in the sky.

During the day, the bright sunlight in our atmosphere scatters and blocks much of this light, making it difficult to observe distant objects. Radio telescopes, on the other hand, work all day and all night because they detect radio waves, which are not affected by sunlight and can be observed during the day.

What is telescope?

A telescope is an optical instrument that is used to magnify distant objects, allowing astronomers to observe and study objects in the sky. Telescopes come in a variety of shapes and sizes and use either lenses or mirrors to gather light and focus it on an eyepiece, allowing a person to observe distant objects in great detail.

In conclusion, Earth-based optical telescopes work best at night because they rely on visible light from distant objects in the sky, which is blocked by the bright sunlight during the day. Radio telescopes, on the other hand, work all day and all night because they detect radio waves, which are not affected by sunlight.
