Answer:

D) Silent mutation on second codon, third amino acid changed from ILE to ASN.

Explanation:

Silent mutations are usually point mutation where you change one nucleotide. Since, the nucleotide changed is the third position, it does not affect the protein being manufactured (it will still put the amino acid Ala) [look up the codon redundancy on youtub.e to understand how awesome nature is!]

On the other hand, the other mutation introduced is Missense mutation where a different Amino acid is added due to change in codon (goes from ILE to ASN).

The pressure of the blood returning to the fish heart is lower than the pressure of the blood returning to the human heart due to differences in their circulatory systems.

A) The concentrations of gases in the blood leaving the fish heart are different from those leaving the human heart because of the differences in their respiratory systems. Fish have gills that extract oxygen from water, which contains a lower concentration of oxygen than air.

Therefore, fish have to extract more oxygen from the water, which results in higher concentrations of oxygen in their blood. In contrast, humans have lungs that extract oxygen from air, which has a higher concentration of oxygen than water. This results in lower concentrations of oxygen in the blood leaving the human heart.

B) The pressure of the blood returning to the fish heart is lower than the pressure of the blood returning to the human heart because fish have a single circulatory system, while humans have a double circulatory system. In a fish, the blood flows from the heart to the gills, where it picks up oxygen and releases carbon dioxide, and then flows to the rest of the body.

The pressure in the gills is lower than the pressure in the rest of the body, which creates a pressure gradient that facilitates the flow of blood. In contrast, humans have two separate circuits - the pulmonary circuit, which carries blood to and from the lungs, and the systemic circuit, which carries blood to and from the rest of the body. The pressure in the systemic circuit is higher than the pressure in the pulmonary circuit, which facilitates the flow of blood in both circuits.

Therefore, the pressure of the blood returning to the fish heart is lower than the pressure of the blood returning to the human heart due to differences in their circulatory systems.

The cell described in the question, which forms concentric layers of plasma membrane around an axon, is most likely a Schwann cell, option (c) is correct.

Schwann cells are a type of glial cell found in the peripheral nervous system (PNS). One of their primary functions is to provide insulation to axons, which promotes the rapid conduction of action potentials. The concentric layers of plasma membrane around the axon form the myelin sheath, which acts as an electrical insulator.

This insulation allows for saltatory conduction, where action potentials "jump" between nodes of Ranvier, significantly increasing the speed of neural transmission. While other options, such as recycling neurotransmitters in synapses or supplying nutrients to neurons, are important functions within the nervous system, the description of concentric layers of plasma membrane specifically points towards the role of Schwann cells in insulation and rapid conduction, option (c) is correct.

If you start off with 12 strands of chromatin how many strand of chromatin do you need to end up with in each cell after meiosis after 3 stages.

In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm).

Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent). The egg and sperm that combine during fertilization must be haploid, or having only one pair of chromosomes, in order to sustain this state.

Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are the gametes.

Nearly every human cell contains 46 chromosomes, 23 of which come from one of our parents and 23 highly similar chromosomes from the other parent. The appropriate number of chromosomes in a cell is crucial.

Therefore, If you start off with 12 strands of chromatin how many strand of chromatin do you need to end up with in each cell after meiosis after 3 stages.

The following statement is false or incorrect: "A nerve impulse occurs if the excitatory and inhibitory effects are equal." Option A is correct.

A nerve impulse, also known as an action potential, is a brief electrical signal that travels along the membrane of a neuron, allowing for rapid communication within the nervous system. The nerve impulse is initiated by the opening of ion channels in response to a depolarizing stimulus, such as the binding of a neurotransmitter molecule to a receptor on the neuron's membrane.

A nerve impulse, occurs when the excitatory effects on the neuron are greater than the inhibitory effects and reach a threshold level of depolarization, triggering the opening of voltage-gated ion channels and resulting in the rapid depolarization of the membrane potential. If the excitatory and inhibitory effects are equal, the membrane potential will not reach the threshold for an action potential, and no nerve impulse will occur.

Most phenotypic traits are complex due to polygenic inheritance and environmental influences.

Phenotypic traits often result from the combined effects of multiple genes (polygenic inheritance) and can be influenced by environmental factors. Punnett Squares, which illustrate single gene pair inheritance, are not suitable for capturing the complexity of such traits. Additionally, environmental factors can interact with genetic factors, leading to variations in trait expression.

To measure complex phenotypic traits, alternative approaches are used. Quantitative measurements, such as height or weight, provide precise numerical values. Statistical analysis helps identify patterns, correlations, and heritability estimates in populations. It involves studying large sample sizes and employing statistical models to understand the contributions of genetic and environmental factors. Molecular genetics advancements have further enhanced our ability to study complex traits at the genetic level.

The given statement "Selective distortion could be described as perceiving stimuli (an event) in a way that makes you feel comfortable cognitively" is False.

Selective distortion refers to the process by which we perceive stimuli in a way that is consistent with our existing beliefs, attitudes, and expectations. This means that we may filter out information that contradicts our preconceptions, or interpret information in a way that reinforces them. This can lead to cognitive dissonance, which is the discomfort or anxiety that we feel when our beliefs and actions are inconsistent with each other.

False. Selective distortion can occur at both conscious and unconscious levels. At the conscious level, we may be aware of the ways in which we are filtering information, and we may be able to consciously control our perceptions to some extent. At the unconscious level, our perceptions may be influenced by our deep-seated beliefs and attitudes, which we may not even be aware of.

Most of our thoughts occur at a conscious level, but there are also many thoughts and perceptions that occur at an unconscious level. These unconscious thoughts and perceptions can be influenced by a wide range of factors, including our past experiences, our cultural background, and our current emotional state.

True. Perception and reality are not necessarily the same thing. Perception refers to the way that we perceive and interpret information through our senses. Reality refers to the objective state of things as they actually exist, independent of our perceptions. However, our perceptions can influence our understanding of reality, and our perceptions may not always be accurate or complete.

Perception and reality can be distinct constructs, but they are also closely related. Our perceptions can be influenced by our expectations, our past experiences, and our cultural background, among other factors. At the same time, our perceptions can also provide us with information about the world around us that is independent of our subjective experiences.

Explanation:

Chemiosmosis is involved in the generation of adenosine triphosphate (ATP), the primary chemical used by the cell for energy.

Chemiosmosis is the passage of ions down an electrochemical gradient over a semipermeable membrane bound structure. The generation of adenosine triphosphate (ATP) by the transport of hydrogen ions (H+) across a membrane during cellular respiration or photosynthesis is a good example. When ions flow through a channel, they generate potential energy, which can be used to power chemical reactions (red). Hydrogen ions, or protons, will diffuse from a high proton concentration zone to a low proton concentration region, and an electrochemical concentration gradient of protons across a membrane can be used to generate ATP. This process is similar to osmosis, the passage of water through a selective membrane, which is why it is named "chemiosmosis".

The acidity or alkalinity of a solution is gauged by its pH. A solution's pH can be determined by how many hydrogen ions are present in it.

The number of hydrogen ions in a sample solution is counted during this pH test. While alkaline substances have a high pH when few hydrogen ions (basic substances) are present, acidic compounds have a low pH when there are many hydrogen ions.

The relationship between pH and the total hydrogen ion concentration can be determined using the pH scale. As a result, pH falls when there are more hydrogen ions present and rises when there are less hydrogen ions. Changing the pH scale by one unit results in a 10-fold difference in hydrogen ion concentration, while changing it by two units results in

85–90% of all intervertebral disc herniations happen at the disc between L4 and L5 or L5 and S1, making the lower back particularly susceptible.

An issue with one of the rubbery cushions (discs) that lie in the spaces between the vertebrae that make up your spine is referred to as a herniated disc.

A spinal disc has a tougher, rubbery exterior covering a soft, jelly-like interior (nucleus) (annulus). A herniated disc, also known as a slipped disc or a ruptured disc, happens when a portion of the nucleus pushes through a tear in the annulus. Although a herniated disc can develop anywhere along the spine, it most frequently does so in the lower back. A herniated disc may cause pain, numbness, or weakness in an arm or leg, depending on where it is located. Many people with herniated discs don't experience any symptoms.
