describe how impulse are transmitted across a synapse
Answers
A tiny electric message moves through a long part of a brain cell called the axon. When a message goes to the end of a nerve, it sends chemicals called neurotransmitters. These substances move through a tiny gap and attach to special parts of another nerve cell's outer covering.
What are the impulse?Messages called impulses are sent from one nerve cell to another through a connection called a synapse. This process is called synaptic transmission. Synapses are connections between nerve cells or between nerve cells and other cells, like muscles or glands.
The neuron sending the signal is called the presynaptic neuron. When a signal travels down a nerve cell, it causes little sacs called vesicles to release chemicals called neurotransmitters.

inquiry based pedagogy is being embraced in principle across the globe. in the last decade , it has been supported by an increasing body of research on its effectiveness. illustrate your understanding of the concept of inquiry based pedagogy with a relevant example
Answers
Inquiry-based pedagogy involves fostering curiosity and active learning. For example, students investigating real-world environmental issues and proposing solutions.
Inquiry-based pedagogy is a teaching approach that promotes active learning and critical thinking through inquiry and exploration. One relevant example of inquiry-based pedagogy is a science classroom where students are encouraged to design and conduct their own experiments. Instead of simply following instructions, students formulate research questions, develop hypotheses, plan and execute experiments, collect and analyze data, and draw conclusions. For instance, students may investigate the effect of different variables on plant growth by manipulating factors like light, water, or soil composition. This approach allows students to engage in authentic scientific practices, develop problem-solving skills, and gain a deeper understanding of the scientific method. By actively participating in their learning process, students develop a sense of ownership and become more engaged, fostering a love for learning and nurturing their ability to explore and discover knowledge independently.For more such questions on Pedagogy:

Carlton and Vanessa are lab partners in their biology class. One of their labs was to run the smell test experiment on each other.
When performing the smell test, Vanessa was quite good at noticing a difference between the various intensities of vanilla and also
the various intensities of evergreen. Although Carlton could distinguish what the vanilla and evergreen smells were, he couldn't tell
there was a difference in the intensities in the vanilla or the evergreen. Based on the information presented in this scenario, which
of the following is true?
Vanessa has a more sensitive difference threshold than Carlton.
Carlton has an impaired absolute threshold.
Vanessa has a better absolute threshold than Carlton.
Carlton has the superior performance with respect to the difference threshold.
Vanessa has an impaired absolute threshold.
Answers
Vanessa has a better absolute threshold and more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.
Carlton and Vanessa were lab partners for a biology class and were asked to run a smell test experiment on each other.
Vanessa was excellent at noticing the difference between various intensities of vanilla and evergreen.
Carlton, on the other hand, couldn't distinguish the difference in the intensities of both vanilla and evergreen, though he could tell the smells of both.
Hence, based on the information provided in the scenario, it can be inferred that Vanessa has a more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.
The two significant aspects that are involved in the scenario are absolute threshold and difference threshold.
The absolute threshold is the smallest quantity of a stimulus that an individual can detect, whereas the difference threshold is the minimum difference in stimuli that an individual can detect.
Carlton could recognize the stimuli's smell but not the difference in the intensity of vanilla and evergreen.
This shows that Carlton has an impaired absolute threshold.
He could not detect the smallest quantity of a stimulus to differentiate between the smells.
Vanessa was quite good at noticing the difference in the intensities of vanilla and evergreen.
This means that Vanessa has a more sensitive difference threshold than Carlton. She could detect the minimum difference in stimuli required to differentiate between smells.
Vanessa also has a better absolute threshold than Carlton as she could detect the smallest quantity of stimulus required to detect the smells.

Anaphase occurs during the M phase (mitosis) of the cell cycle and is not represented by any of the provided options (A, B, C, or D).
Anaphase is a critical stage in cell division, specifically in mitosis or meiosis. It occurs after metaphase and before telophase. During anaphase, the sister chromatids, which are replicated chromosomes held together by a centromere, separate and move towards opposite ends of the cell.In the context of the cell cycle, anaphase takes place during mitosis. The cell cycle consists of four phases: G1 (gap 1), S (synthesis), G2 (gap 2), and M (mitosis). Mitosis is the M phase, which further consists of four stages: prophase, metaphase, anaphase, and telophase.Therefore, the correct answer is not provided in the given options. Anaphase occurs during the M phase or mitosis and is not associated with any specific phase (A, B, C, or D) mentioned in the question.

Indicate whether each statement is true or false: 1. Compliance is the tendency for blood vessel volume to increase as blood pressure decreases. True 2. Blood vessels with a large compliance exhibit a small increase in volume when the pressure increases a small amount. True 3. Venous compliance is approximately 24X greater than arterial compliance, so as venous pressure increases the volume of veins greatly increases. True
Answers
Answer:
1. False
2. False
3. True
Explanation:
1. Compliance is the capacity of a container to increase in size to allow it hold more content. Blood vessel, arteries and veins expand (increase in volume) to be able to accommodate a surge in blood flow, which is as a result of an increase in pressure of the blood from the heart pumping of the blood
Therefore, compliance in the tendency for blood vessel volume to increase as the blood pressure increases not decrease
The statement is false
2. A large compliance is indicative of being highly sensitive to changes in pressure
Compliance, C = ΔV/ΔP
From the above equation, a blood vessel with a large compliance, exhibit a large increase in volume when the increase in pressure is small
Therefore, the statement 'Blood vessels with a large compliance exhibit a small increase in volume when pressure increases a small amount; is false
3. The compliance of the vein ranges from 10 to 20 times (30 times in some literature) greater than arteries. A factor which can be affected by the vascular smooth muscle contraction or relaxation
Therefore, the statement, 'venous compliance is approximately 24 times larger than arterial compliance, so as venous pressure increases the volume of veins greatly increases' is true
why might a rock layer not contain any fossils?
Answers
The rock layer may have formed before life existed or may have eroded away any existing fossils.
There are a few reasons why a rock layer may not contain any fossils. One reason is that the rock layer may have formed before life existed on Earth, such as in the case of igneous rocks that form from volcanic activity.
Another reason is that the rock layer may have formed in an environment that was not conducive to preserving fossils, such as a high-energy riverbed or a desert.
Additionally, the rock layer may have been eroded away over time, destroying any existing fossils. Finally, it is possible that fossils were present in the rock layer but were not discovered or identified during the excavation process.
