why is pyruvate kinase called pyruvate kinase and not pep-adp phosphotransferase or something like that

Answer:

Explanation:

Insulin and glucagon are two hormones secreted by the pancreas involved in glucose metabolism.

insulin is secreted by the beta cells of the islets of Langerhans and contributes to lowering blood sugar levels. In this case, insulin causes the body's cells to absorb blood glucose in order to reduce it.

while glucagon is secreted by the alpha cells of the islets of Langerhans and contributes to the increase in blood glucose concentration. In this case, glucagon stimulates the liver to release glucose into the bloodstream.

since insulin is secreted when there is a lot of glucose in the blood and glucagon when there is little sugar in the blood, these two mechanisms are opposite and regulate each other, to achieve homeostasis or balance in the organism.

D is the answer

Explanation:

Hydraulic facturing, aka fracking, uses toxic chemicals above some regulations which may lead to a leak into water supplies and therefore contaminate it.

It has not much to do with coal, more to do with oil and natural gases

Because of fracking now making it accessible to reach sources in vast number that were previously unacessible, it leads to decreases in gas prices

Answer:

It is because humans have much larger genomes than bacteria

Explanation:

It is because humans have much larger genomes than bacteria. The largest bacterial genome ; human clocks. But corn is about 3 times that, spruce is twice again that and some plants go even bigger. For example, every one of tulip’s chromosomes is about one human genome in size, and bacteria are haploid, humans are diploid. That makes assembling the DNA fragments much more tricky, as you don’t want to have a final sequence that switches between the two haplotypes.

Identifying genes in bacterial genomes is less complex than identifying genes in the human genome as the bacterial genomes are less complex.

An worldwide studies attempt known as the Human Genome Project, which labored to decide the series of the human genome and discover the genes that it contains, envisioned that people have among 20,000 and 25,000 genes.

The genomes of better animals (including people) are nonetheless extra complicated and comprise massive quantities of noncoding DNA. Thus, most effectively a small fraction of the 3 × 109 base pairs of the human genome is anticipated to correspond to protein-coding series.

The amino acids would be most similar to the ingredients used in the recipe.

When the mRNA moves out of the nucleus, it then gives the instructions (the genetic sequence) to someone else, which is tRNA. During translation, the tRNA and mRNA complex reads the genetic sequence and then binds required amino acids, sequentially. Thus, the combined amino acid chain forms the desired protein.

Therefore, the amino acids are the ingredients and the protein is the final dish.

The nerve that may be cut to decrease stomach acid output and decrease the likelihood of ulcers forming in the jejunum at its junction with the stomach is the vagus nerve. The vagus nerve is responsible for controlling various functions in the gastrointestinal tract, including the production of stomach acid.

By cutting the vagus nerve, the amount of acid produced by the stomach can be reduced, which may help to prevent the formation of ulcers in the jejunum. However, it is important to note that cutting the vagus nerve may also have other effects on the digestive system, including slowing down digestion and reducing the body's ability to absorb nutrients. Therefore, this procedure is typically only recommended in cases where other treatments for ulcers have failed, and only after careful consideration of the potential risks and benefits. It is also important to note that cutting the vagus nerve is a surgical procedure that should only be performed by a qualified healthcare professional.

The protein is subjected to hydrolysis by cyanogen bromide, which cleaves the polypeptide chain at the carboxyl side of methionine residues, generating smaller peptides.

In this case, the protein has three methionines at positions 1, 90, and 520, so it will be cleaved into four fragments:

Fragment 1: From the N-terminus to methionine 1

Fragment 2: From methionine 1 to methionine 90

Fragment 3: From methionine 90 to methionine 520

Fragment 4: From methionine 520 to the C-terminus

The size exclusion chromatography column has a size exclusion limit of 200 kDa, meaning that molecules larger than 200 kDa will elute first, followed by smaller molecules. The molecular weight of the protein is 68 kDa, which is below the size exclusion limit, so it will elute later than larger molecules but earlier than smaller molecules.

Since the protein is cleaved into four fragments, each fragment will have a different molecular weight and will elute at a different time. Therefore, we expect to see four peaks in the chromatogram corresponding to each fragment. However, we don't know the size of each fragment, so we cannot predict the order or position of the peaks.

Therefore, the total number of peaks in the chromatogram will be four.

Although skeletal muscle fibers cannot divide, new muscle fibers can be produced through the division of muscle stem cells. Muscle stem cells are also known as satellite cells. These cells are located between the plasma membrane and the basement membrane of skeletal muscle fibers. They help to repair and maintain the muscle tissues. When the muscle is damaged, the satellite cells become active.

The cells divide to form new muscle cells or myoblasts. These myoblasts are then fused together to form new muscle fibers or myotubes. This process is known as myogenesis. As the myotubes mature, they become multinucleated myofibers. These myofibers can be as long as the entire muscle and they contract in response to electrical impulses from the nervous system.

Satellite cells play a crucial role in muscle regeneration and hypertrophy. When the muscle is subjected to resistance exercise, the satellite cells are activated. They proliferate and differentiate to form new myofibers. This increases the size and strength of the muscle.

Therefore, muscle stem cells play a crucial role in muscle adaptation to exercise and injury. In conclusion, although skeletal muscle fibers cannot divide, new muscle fibers can be produced through the division of muscle stem cells. This is a crucial process that allows the muscle to repair and adapt to different stimuli.

Individuals with beneficial traits are more likely to survive and reproduce.

Individuals within a population can have different traits because of genetic variation.

Individuals with beneficial traits are more likely to survive and reproduce in a changing environment.

Species become more different from their ancestors over time.

Fossil record shows that different species have evolved over time; DNA sequences show that different species share similar genes; Anatomy and embryology show that different species have similar structures.

The fossil record shows that fish evolved into amphibians, which evolved into reptiles, which evolved into mammals; DNA sequences show that humans and fish share many similar genes; The embryos of humans and fish have many similar structures.

1. Natural selection is the process by which individuals with certain traits re more likely to survive and reproduce than individuals with other traits. This is because the individuals with the beneficial traits are better able to compete for resources, such as food and mates.

2. This means that there are different versions of genes in the population. Some of these genes give individuals an advantage, such as being able to swim faster or see better.

3. Natural selection and changes in the environment can both contribute to adaptation. For example, if the environment becomes warmer, then individuals with traits that help them to cool down, such as sweating, will be more likely to survive.

4. The adaptation of species over time is what drives evolution. As species adapt to their environment, they become more different from their ancestors. Over millions of years, these differences can become so great that the species are no longer recognizable as being related.

5. There are many lines of evidence that support the theory of common ancestry. Three of the most important lines of evidence are the fossil record, DNA sequences, and anatomy and embryology. The fossil record shows that different species have evolved over time. DNA sequences show that different species share similar genes. Anatomy and embryology show that different species have similar structures and development.

Answer:

Climate refers to long-term patterns or trends of meteorological conditions.

The property of a neuron that is best exemplified by observing changes in an electrical charge passing down its plasma membrane is its ability to conduct electrical impulses, also known as its excitability or electrical excitability.

Neurons are specialized cells that form the building blocks of the nervous system. One of the key functions of neurons is to transmit electrical signals, known as action potentials, along their plasma membrane. This process is made possible by the neuron's ability to generate and propagate changes in electrical charge.

When a neuron receives a stimulus, such as a chemical signal or sensory input, neurotransmitter it can undergo a change in its membrane potential, resulting in depolarization. This change in electrical charge triggers the opening of voltage-gated ion channels, allowing the flow of ions across the membrane and the propagation of the electrical impulse.

By observing changes in the electrical charge passing down the plasma membrane of a neuron, researchers can study its ability to transmit and process information. This property of neurons, known as electrical excitability or the ability to conduct electrical impulses, is fundamental to their role in transmitting signals within the nervous system and facilitating communication between different parts of the body.

Before transcription can begin, RNA polymerase must find the location and direction of a gene on the chromosome based on its sequence. RNA polymerase ends transcription at a clear origin located at the end of a gene. It is common for amino acid biosynthetic genes to be transcriptionally activated in the presence of tRNAs as a result of the Stringent response, which requires charged sigma factor to bind RNA polymerase. An sRNA can inhibit mRNA translation by the ribosome through complementary base-pairing to the sequence in its target mRNA. During DNA replication, the sequence of the daughter strand being synthesized is determined by complementary base-pairing with the parent template strand, however, DNA polymerase can incorporate a base-pair that can result in a point mutation if it is not repaired. A bacteria can repair these mistakes and distinguish the original parent strand of DNA from the new daughter strand of DNA through methylation of certain nucleotides. In order to replicate their genomes, all SSRNA viruses must package an RNA-dependent RNA polymerase within their capsid.

The point mutation that is unlikely to change a protein's ability to function is a silent mutation.

A point mutation is a change in a single nucleotide within a DNA sequence. There are three types of point mutations: silent mutations, missense mutations, and nonsense mutations.

Silent mutations occur when the change in the DNA sequence does not alter the amino acid encoded by the corresponding codon, which means the protein's structure and function remain unchanged. Missense mutations lead to a change in the amino acid sequence, which may affect protein function, while nonsense mutations create a premature stop codon, usually resulting in a nonfunctional protein.

Among the different types of point mutations, silent mutations are the least likely to change a protein's ability to function, as they do not cause a change in the amino acid sequence of the protein.
