What is an advantage of a degenerate genetic code?
Mutations are more likely to alter proteins, increasing the rate of evolution.
Mutations are less likely to alter protein sequence, decreasing the chances that a mutation will have deleterious consequences to the organism.
It increases the number of different proteins that can be coded by each gene.
It decreases the total number of tRNAs that have to be made.
Answer:
The first one
Explanation:
This is because there are no base triplets that are unused in the cell. All of the bases are used since more than one triplet of DNA bases are coded for amino acids
An advantage of a degenerate genetic code is that 'mutations are less likely to alter protein sequence, decreasing the chances that a mutation will have deleterious consequences to the organism'.
The genetic code refers to the fact that the linear order of nucleotides in DNA and also in mRNA determines the order in which amino acids are added to the protein during translation.The genetic code is said to be redundant or degenerate because different triplets of nucleotides or codons in the mRNA can encode the same amino acid.For example, leucine can be encoded by six different synonym codons (i.e., CTT, CTC, CTA, CTG, TTA, and TTG).In consequence, mutations that generate synonym codons don't have a direct effect on the synthesized protein.In conclusion, an advantage of a degenerate genetic code is that 'mutations are less likely to alter protein sequence, decreasing the chances that a mutation will have deleterious consequences to the organism'.

Which of the following describes research that that would be considered basic science?
I think it's A. Tell me if I'm wrong.
Please leave a thanks.
Answer:
A
Explanation: Basic research, or fundamental research, is focused on generating scientific knowledge that helps us to understand the nature of the world around us. Therefore, the aim of basic research is not to use that knowledge in specific applications. This would be the case of the investigation if someone tried to respond how the growth of a desert plant would be in conditions of excess water. This research would contribute to general knowledge without a concrete practical application.
Technique of placing a desired plant stem into another, more adequate root system is _____.
Answer:
grafting
Explanation:
The grafting is a horticultural technique that enables us to place a stem of a desired plant into another, more adequate already developed root system. This is done by cutting a branch from the already established plant, on the place of the precisely made cut we joint the desired stem, and then joint them together, be it with wax, mud, or a sellotape. The stem that has been placed on the established plant will be able to get the nutrients from it in this manner and become part of it, but it will produce different fruits from the established plant, it will produce its own fruits. This technique of course works only on plants that are more closely related and belong to the same family.
Which of the following processes breaks down glucose?
A:)Excretion
B:)Photosynthesis
C:)Reproduction
D:)Respiration
Answer:
The correct answer is option D:) "Respiration".
Explanation:
In Biology, respiration is defined as the way a cell or an organism obtains energy by combining oxygen and glucose in a biochemical process that results in the release of carbon dioxide, water and adenosine triphosphate (ATP, the molecule that carries energy for almost any cellular process). These molecules are obtained by the gradually broken down of glucose, having the overall chemical equation of C6H12O6 + 6O2 → 6CO2 + 6H2O (glucose + oxygen -> carbon dioxide + water)
The process that breaks down glucose is respiration.
Which process breaks down glucose?
Glucose is a molecule that stores energy, and during respiration, it is broken down in a series of chemical reactions to release energy. This energy is then utilized by cells for various metabolic processes, such as growth, movement, and maintaining essential functions.
Option A, excretion, refers to the elimination of waste products from the body and is not directly involved in breaking down glucose.
Option B, photosynthesis, is the process by which plants and some other organisms convert light energy into chemical energy, producing glucose from carbon dioxide and water. It is the opposite process of glucose breakdown.
Option C, reproduction, refers to the process of producing offspring and is not directly related to breaking down glucose.
Therefore, the correct answer is D) Respiration.

Gaucher disease is the most common of lipid storage diseases in humans. It is caused by a deficiency of an enzyme necessary for lipid metabolism. This leads to a collection of fatty material in organs of the body including the spleen, liver, kidneys, lungs, brain, and bone marrow. Using your knowledge of the structure of eukaryotic cells, identify the statement below that best explains how internal membranes and the organelles of cells would be involved in Gaucher disease. Gaucher disease is the most common of lipid storage diseases in humans. It is caused by a deficiency of an enzyme necessary for lipid metabolism. This leads to a collection of fatty material in organs of the body including the spleen, liver, kidneys, lungs, brain, and bone marrow. Using your knowledge of the structure of eukaryotic cells, identify the statement below that best explains how internal membranes and the organelles of cells would be involved in Gaucher disease. The lysosomes lack sufficient amounts of enzymes necessary for the metabolism of lipids. The rough endoplasmic reticulum contains too many ribosomes which results in an overproduction of the enzyme involved in carbohydrate catalysis. The Golgi apparatus produces vesicles with faulty membranes that leak their contents into the cytoplasm of the cell. The mitochondria are most likely defective and do not produce adequate amounts of ATP needed for cellular respiration.
Answer:
The lysosomes lack sufficient amounts of enzymes necessary for the metabolism of lipids.
Explanation:
Lysosomes are a membrane-bound organelles with acidic interior that enables the function of hydrolytic enzymes. So, the main role of lysosomes is degradation of macromolecules (such as lipids). Low pH (about 5) is suitable for the action of enzymes involved in hydrolysis (hydrolases) and there are about 50 of them inside the lysosome. Beside macromolecules, lysosomes degrade organelles, but also can digest themselves via autophagy (e.g. when cell is under stress).
Lysosomes are also involved in plasma membrane repair, defend against pathogens (macrophages), cell signaling, metabolism etc.
Gaucher disease, due to a deficiency in a specific enzyme, leads to impaired lipid metabolism. This results in fatty material accumulating in organs and within cells. The disease primarily affects organelles such as lysosomes and the endoplasmic reticulum but impacts the overall functioning of the cell.
Explanation:In Gaucher disease, the inability to metabolize lipids due to a deficiency in a particular enzyme leads to the accumulation of fatty material in various organs. Key to understanding the effect of this disease on eukaryotic cells is the structure of the cell and its organelles, specifically the lysosomes and endoplasmic reticulum. Lysosomes, which contain enzymes for digesting cellular components and foreign material, fail to break down lipids, resulting in their buildup within the cell.
The endoplasmic reticulum (ER) plays a significant role in lipid synthesis. Therefore, a breakdown in this process could trigger the accumulation of unprocessed lipids, impacting the overall functioning of the cell. It's significant to note that while the lysosomes and ER are centrally implicated, the overall interconnected dependency of the cell on its organelles implies that all organelles are affected, to various degrees, due to enzymatic deficiency. For example, the Golgi apparatus is involved in lipid modification and transportation; a metabolic pathway is disrupted by the disease.
The disease's impact can further disrupt the function of the mitochondria, affecting ATP production necessary for cellular respiration and metabolism. Therefore, while primarily a failure of lipid metabolism due to enzymatic deficiency, Gaucher disease's impact is felt across an array of organelle functions, disrupting the normal functioning of eukaryotic cells.

Colorblindness is a sex-linked trait. A mother with normal vision and a man who is colorblind have a colorblind daughter. What statement MUST be true about the parents?
Answer:
The child must have a father who is colorblind and a mother who is a carrier/ is colorblind.
Explanation:
The genetic code for color blindness is carried upon the x chromosome. This means that a male- who has only one X chromosome- only needs their mother to be a carrier to be colorblind. Women on the other hand, need two to be color blind, as the faulty x chromosome can be weeded out by the other.
Therefore, the father, in order to pass on the colorblindness, must be colorblind himself, whereas the mother only needs to be a carrier (or can be completely color blind herself).
Answer:
A) The mother is a heterozygous carrier
Explanation:
A) The mother is a heterozygous carrier. - only one that makes sense
B) The father is a heterozygous carrier. - he is double recessive
C) The mother cannot have the colorblind gene. - that is possible
D) The mother is homozygous dominant for normal vision. - that would mean the 100% of the offspring would be normal

Answer:
1. What are some of the threats to dogfish sharks?
Direct threats such as fishing can lead to the depletion of dogfish sharks as well as indirect threats like water pollution, habitat changes, damage and loss due to coastal development. Like other shark species, they have low reproduction rates and they grow slowly and mature late.
2. What abnormalities, if any, were detected in the necropsy results? How may these factors have contributed to the shark’s death?
There was an abnormality that was detected in the necropsy revealing elevated levels of methyl mercury in the shark’s liver. In addition, there was also the presence of plastic in the stomach of the fish. Both of these factors contributed to the shark’s death.
3. Describe the stomach contents of the shark. What do the stomach contents indicate regarding the dogfish shark’s eating habits?
Inside the shark stomach were found the normal fish and shrimp which is part of the shark's diet. However, a ball of plastic was also found in it. This is an indication of pollution in the shark's environment, a thing that sharks unknowingly take in foreign objects that float along with the fish.
4. What do you predict was the main cause of death? Discuss what other factors may have contributed to the shark’s death.
The main cause of the death of the dogfish shark is pollution of its habitat. The lack of clean water and lack of oxygen have greatly affected the sharks organs and health. The presence of waste materials such as plastic being ingested by the fish is in itself a killer.
5. Could this have been prevented? What can be done to help preserve this species?
Yes, the death and depletion of sharks can be prevented. By making sure that the ecosystem is free from pollution and clear of waste materials, humans as custodians of the planet earth are responsible and accountable to safeguard every living thing.

C. Fertilization would cause crossing-over and recombination of genes.
D. Cells of the new individual would have double the necessary number of chromosomes.
Answer D. Cells of the new individual would have double the necessary number of chromosomes.
Explanation:
The result of fertilization of an ovum by a sperm cell forms a new individual that would have double the necessary number of chromosomes. Thus, the correct option for this question is D.
What is Fertilization?Fertilization may be characterized as a biological event that significantly involves the fusion of a male gamete with a female gamete in order to produce a zygote. It is generally the union of two gametes. The zygote that is produced is diploid in nature.
The division of sex cells or gamete cells is facilitated through the process of meiosis. This process of cell division produces two daughter cells that are genetically dissimilar to the parent one. It is also known as the reductional division.
But if the process of division of sex cells is accomplished through mitosis, it would eventually produce a new individual that would have double the necessary number of chromosomes.

You scoop up a water sample from a local pond nearby, because you are curious about the possible microbes that might live there. After looking at several slides that held drops of the sample, you noticed two different kinds of cells: One kind was very small and had no separate internal structures; the other kind was much larger, and it contained several kinds of internal structures that were physically different from each other. Please name each cell and briefly describe their overall similarities and differences.
Answer:
The cell which is small and with no internal structures is most likely prokaryotic cell, while the larger cell with internal structures is eukaryotic cell.
Explanation:
There are two main types of cells among living organisms:
Eukaryotic cell (plants, animals, fungi) which is more compound, conntains nucleus with genetic material in it, membrane-bound organelles (mitochondria, Golgi apparatus, lysosomes etc). Because of their complex structure, the process within such cells are often more comlex then those in prokaryotes. Eukaryotic organisms are usually multicellularProkaryotic cell is simple cell found in Archea and Bacteria kingdom. It doesn't have nucleus neither membrane-bound organelles. Genetic material of these cell is located within the cytoplasm together with proteins and metabolites. First living cell was prokaryotic cell. Organisms that are prokaryotic are usually unicellular.The very small cells with no separate internal structures are likely prokaryotic cells while the larger cells with distinct internal structures are likely eukaryotic cells. Both share common structures but differ in size and complexity.
Explanation:The two types of cells you noticed in your water sample from the pond likely represent prokaryotic and eukaryotic cells. Prokaryotic cells are generally smaller and do not contain separatemembrane-bound internal structures. They have a simple structure with nucleic acids (DNA and RNA) floating freely within the cell. Prokaryotes like bacteria are examples of organisms that possess this cell type.
On the other hand eukaryotic cells are typically larger and contain several kinds of internal structures, called organelles, that are physically separate from each other. The DNA of eukaryotic cells is contained within a nucleus. Examples of eukaryotic cells can be found in organisms like plants and animals.
Both cell types share common structures like a plasma membrane, cytoplasm, genetic material (nucleic acids), and ribosomes. However, their size and the presence or absence of membrane-bound organelles differentiate them significantly.

They can sense the improper fit of an amino acid and hydrolyze the intermediate prior to attachment to the tRNA. There is a short window of opportunity for the enzyme to hydrolyze the amino acid-tRNA bond before it is released for translation. The tRNA has a polynucleotide domain that is responsible for proofreading. Aminoacyl-tRNA synthetases do not proofread.
Answer: evidence supporting the therory slowly accumulated
Explanation:
The answer is B
Answer:
They can sense the improper fit of an amino acid and hydrolyze the intermediate prior to attachment to the tRNA. There is a short window of opportunity for the enzyme to hydrolyze the amino acid-tRNA bond before it is released for translation.Explanation:
An aminoacyl tRNA synthetase (aaRS) is a very important exhima during protein synthesis that is made through translation. This enzyme is an important factor not only for regulating the translation process, but also for the efficiency of a newly formed protein. This is because this enzyme is responsible for maintaining the fidelity of the genetic code during protein formation. This is done by detecting improper adjustment of an amino acid and hydrolyzing the intermediate prior to tRNA binding. furthermore, this enzyme may hydrolyze the amino acid-tRNA bond before being released for translation.
Which of the following statements is TRUE regarding CO2 in the mammalian bloodstream? In the mammalian bloodstream, CO2 is much less soluble than O2. CO2 is mainly transported through the mammalian bloodstream in the form of bicarbonate ions or carbonic acid. Unlike oxygen, CO2 is transported through the mammalian bloodstream by myoglobin. All CO2 is transported through the mammalian bloodstream as a dissolved gas, and is carried directly in the plasma. Like oxygen, CO2 is transported through the mammalian bloodstream via hemoglobin; however, CO2 binds to hemoglobin at β subunits rather than heme groups.
Answer:
The correct option is: CO2 IS MAINLY TRANSPORTED THROUGH THE MAMMALIAN BLOODSTREAM IN FORM OF BICARBONATE ION OR CARBONIC ACID.
Explanation:
Carbon dioxide is eliminated from the human body via three different methods. The first method of elimination is direct dissolution in the blood: in this case, carbon dioxide dissolves in the blood and is excreted via the lungs. About 7% of all carbon dioxide are eliminated through this method.
The second method involves the binding of carbon dioxide to hemoglobin. This binding is reversible and the carbon dioxide can easily dissociate from the hemoglobin in order to be excreted in the lungs. About 10% of carbon dioxide are eliminated from the body by this method.
The third method of carbon dioxide elimination involves the formation of bicarbonates ions and carbonic acid. Majority of the carbon dioxide in the body ( about 85%) are eliminated from the body through this method.

Answer:
TrueFinal answer:
Cinder cone volcanoes do not have alternating layers of ejected material; this statement is false. They are built primarily from pyroclastics, while composite volcanoes have the characteristic alternating layers of lava flows and pyroclastics.
Explanation:
The statement that cinder cone volcanoes have alternating layers of ejected material is false. Cinder cones are typically built from pyroclastic material, which includes cinders, volcanic ash, and volcanic bombs that have been ejected during explosive volcanic eruptions. These cinders accumulate around the volcanic vent, forming a cone with steep sides. Unlike composite volcanoes (also known as stratovolcanoes) which indeed have alternating layers of lava flows and pyroclastics, cinder cone volcanoes are not characterized by such layering.
In contrast, composite volcanoes have steep-sided cones built from alternating flows of lava and pyroclastics. Shield volcanoes, on the other hand, have broad, low-angled slopes and are built layer on layer of fluid lava.
