What RNA species can be purified using this method? solvent flow 1 bead with covalently attached poly-dT desired RNA species other RNAS pass through Eukaryotic rRNA Both, the eukaryotic and bacterial mRNAs ō ō Ō Bacterial mRNA Eukaryotic mRNA

Answers

Answer 1

Answer: The RNA species that can be purified using affinity chromatography with beads coated with poly-deoxythymidine (poly-dT) are the mRNA molecules, both eukaryotic and bacterial. The poly-dT chains specifically bind to the poly-adenine tail present in most messenger RNAs, allowing them to be selectively retained while other RNAs flow through the column. Eukaryotic rRNA would not be purified by this method, as it does not contain a poly-adenine tail.

Explanation:

Answer 2

The RNA species that can be purified using affinity chromatography with beads coated with chains of poly-deoxythymidine (poly-dT) are eukaryotic mRNA.

An immobilised ligand and its binding partner engage in a specific binding interaction, which forms the basis of the separation technique known as affinity chromatography. Examples include interactions between an enzyme and a substrate, an enzyme and an inhibitor.

This is because eukaryotic mRNA molecules have a poly-A tail at their 3' end, which can bind to the poly-dT chains on the beads. The other RNA species, such as eukaryotic rRNA, bacterial mRNA, and bacterial rRNA, do not have a poly-A tail and therefore will not bind to the poly-dT chains.

As a result, these unwanted RNAs will flow through the column while the desired eukaryotic mRNA will stick to the beads. The retained eukaryotic mRNA can then be eluted from the beads using a solvent.

According to the Law of Superposition, in undisturbed, horizontal, sedimentary rock layers, the oldest layer is at the bottom. Each higher layer is younger than the rocks below it. Why is it important that the rock layers be undisturbed?
A. If the rock layers are disturbed, sedimentary rock will turn into an intrusion
B. If the rock layers are disturbed, the absolute age of the rocks will change
C. If the rock layers are disturbed, certain layers may be missing or relocated
D. If the rock layers are disturbed, the Law of Superposition is proven wrong
Please explain why you chose this answer

Answers

The correct answer is C. If the rock layers are disturbed, certain layers may be missing or relocated.

The Law of Superposition is a fundamental principle used in geology to determine the relative ages of rock layers. It states that in an undisturbed sequence of sedimentary rocks, the oldest rocks are at the bottom and the youngest rocks are at the top. This is because sedimentary rocks are formed by the accumulation of sediment over time, with each layer representing a snapshot of the environment at a particular point in time.

If the rock layers are disturbed, such as by folding, faulting, or erosion, the original order of the layers can be disrupted. In extreme cases, layers can be overturned or completely removed, leading to missing or relocated layers. This can make it difficult or impossible to use the Law of Superposition to determine the relative ages of the remaining layers.

Calculate the energy yield in ATP equivalents (assuming an active electron transport chain) when valine is degraded completely to CO2. Justify your answers by using compound names only to describe the relevant pathways (but not the electron transport chain). Structures may be used in place of compound names.

Answers

The valine catabolic pathway converts valine into pyruvate, NH3, and NADH when it is completely broken down to CO2. Pyruvate then enters the tricarboxylic acid (TCA) cycle, which, through a series of reactions, produces ATP and reducing equivalents (NADH and FADH2) as well.

Justify your answers by using compound names only to describe the relevant pathways (but not the electron transport chain).

When valine is completely broken down to CO2, there is a total energy yield of about 19 ATP equivalents. This is caused by the 3 ATP equivalents produced by the TCA cycle, 15 ATP equivalents produced by the ETC, and 1 ATP equivalent produced by glycolysis. Depending on the specific electron transport chain utilised, the ETC can produce a different number of ATP molecules. Overall, there are numerous pathways and reactions involved in the breakdown of valine to CO2. The organism can use the significant amount of ATP that is ultimately produced by it for a variety of energy-dependent processes. Determine the energy yield in ATP equivalents when valine is completely converted to CO2 (under the assumption of an active electron transport chain). Only use compound names to describe the pertinent pathways in your justifications (but not the electron transport chain). Compound names can be replaced by structures.

How is wind related to air pressure??
(in your own words)

Answers

Wind is related to air pressure because differences in air pressure create areas of high and low pressure that can cause air to move from areas of high pressure to areas of low pressure, resulting in wind.

In general, air moves from areas of high pressure to areas of low pressure due to the pressure gradient force. The greater the difference in pressure between two points, the stronger the pressure gradient force and the faster the air will move. The direction of the wind is determined by the direction of the pressure gradient, with the air flowing perpendicular to the isobars (lines of equal pressure) from high pressure to low pressure.

The differences in air pressure that create wind are often caused by temperature differences in the atmosphere. For example, warm air rises and creates an area of low pressure, while cool air sinks and creates an area of high pressure. These pressure differences can be further amplified by other factors such as the rotation of the Earth, the presence of mountains or other topographical features, and the movement of weather systems.

In summary, wind is related to air pressure because differences in air pressure create a pressure gradient force that causes air to move from areas of high pressure to areas of low pressure, resulting in the movement of wind.

FILL IN THE BLANK. A newly discovered fungal pathogen has recently begun to infect and kill many species of amphibians. When the pathogen infects a new amphibian species, it evolves specialized defenses against that amphibian species' immune system. This specialization makes strains of this pathogen on one amphibian species genetically distinct and unable to interbreed with pathogens on different amphibian species. Further, once the pathogen infects an individual, populations in different parts of their host's body evolve uniquely to deal with different environmental challenges. While individuals in different parts of the host's body are still genetically similar enough to interbreed, they end up having very different phenotypes. The two broad types of evolution occurring in this pathogen are _____ speciation and _____ by _____ selection.

Answers

The two broad types of evolution occurring in this pathogen are allopatric speciation and adaptation by natural selection.

Allopatric speciation occurs when a population becomes geographically isolated and diverges genetically, leading to the formation of new species. In the case of the fungal pathogen, the different amphibian species act as geographic barriers, causing the pathogen to evolve specialized defenses against each amphibian species' immune system and leading to the formation of genetically distinct strains of the pathogen that are unable to interbreed.

Adaptation by natural selection occurs when individuals with certain traits are better suited to their environment and are therefore more likely to survive and reproduce.

In the case of the fungal pathogen, populations in different parts of the host's body are exposed to different environmental challenges and evolve uniquely to deal with these challenges.

Answers

If an object had a mass of 5 kilograms, the weight of the object measured on a spring scale in the unit of Newtons is 50N.

The force that causes a mass of one kilogramme to accelerate by one metre per second per second is known as 1 kgm/s2. It bears Isaac Newton's name in honour of his contributions to classical mechanics, particularly Newton's second rule of motion.

we have 1 kg = 10 N

so 5 kg = 5 x 10 = 50 N.

The force exerted on an item by gravity is known as its weight.

Weight is sometimes described as a vector quantity, or the gravitational force exerted on the object, in certain common textbooks. Some people refer to weight as a scalar quantity that measures the gravitational force's strength. Others describe it as the strength of the force applied to a body by systems that work to counteract the effects of gravity. For example, a spring scale measures weight.

The relationships of living things are complex and interconnected. Atoms combine to form molecules, which combine to form cells, which work together to form tissues, organs, and organ systems.

Atoms are the smallest unit of matter that retain the properties of an element. They are the building blocks of everything in the universe and are composed of a nucleus containing positively charged protons and neutrally charged neutrons, surrounded by negatively charged electrons.

Molecules are formed when two or more atoms combine chemically through covalent, ionic or hydrogen bonding to form a stable unit. Molecules can be made up of the same type of atoms (such as O2) or different types of atoms (such as H2O).

Cells are the basic structural and functional unit of life. They are the smallest unit of life that can perform all the necessary functions, such as growth, metabolism, and reproduction. Cells are divided into two main types: prokaryotic and eukaryotic.

Tissues are a group of similar cells that work together to perform a specific function. For example, muscle tissue is composed of muscle cells that work together to allow movement.

Organs are made up of several different tissues that work together to perform a specific function. For example, the heart is an organ composed of muscle tissue, nervous tissue, and connective tissue that work together to pump blood throughout the body.

Organ systems are a group of organs that work together to perform a specific function. For example, the circulatory system is composed of the heart, blood vessels, and blood, and works to transport oxygen and nutrients throughout the body.

An organism is a living thing composed of one or more cells. Organisms can be unicellular, such as bacteria or amoeba, or multicellular, such as plants or animals. Organisms can also be classified into different kingdoms, such as animalia, plantae, fungi, protista, and monera.

Stages of complete and incomplete metamorphosis

The transformation of an organism through its whole life cycle, including the various stages of egg, larva, pupa, and adulthood, is known as complete metamorphosis. Butterflies, moths, and beetles are some organisms that undergo complete metamorphosis.

Egg: The life cycle's first stage and the start of the full metamorphosis, respectively. The embryo of the creature is housed inside the egg, which is a tiny, often oval-shaped structure.
Larva: The embryo will mature into a larva, which is typically a worm-like creature when the egg hatches. In order to prepare for the forthcoming pupal stage, the organism will feed and expand during this stage. Maggots, grubs, and caterpillars are a few examples of larvae.
Pupa: The larva will change into its adult form during the pupal stage, which is a resting stage. The larva will be enclosed in a puparium at this stage as protection. Chrysalis, pupal cases, and cocoons are a few examples of pupa.
Adult: The organism's adult stage marks the end of its full metamorphosis.

A reaction that uses the absence of hemolysis of red blood cells to indicate an antigen-antibody reaction is called a complement fixation reaction.

Complement fixation is a diagnostic test that is commonly used to detect the presence of antibodies or antigens in a patient's serum. The test involves adding a known antigen to a patient's serum and then adding a source of complement, which is a group of proteins that are involved in the immune response. If the patient has antibodies to the antigen, the antibodies will bind to the antigen and activate the complement system. One of the consequences of complement activation is the lysis, or destruction, of red blood cells.

Explain why it is unusual for Calix to be a male calico cat.

Answers

Calico cats are typically female due to the genetics of their coat color. The gene responsible for the orange and black patches in calico cats is located on the X chromosome. Female cats have two X chromosomes, which means they can have two different versions of the gene. As a result, female cats can have both orange and black patches in their fur.

However, male cats only have one X chromosome and one Y chromosome. This means they can only inherit one version of the gene responsible for calico coat color. In order for a male cat to be calico, he would need to have a rare genetic condition where he has an extra X chromosome (XXY), which is commonly known as Klinefelter syndrome. This condition is very rare in cats, which is why it's unusual for Calix to be a male calico cat.
