Please answer both parts of this question and include a model.
1. Describe this mode of propagation, and draw a model to supplement your description. 2. Explain how it differs from the mode of propagation along the neuron.
Answers
1. In passive propagation, as the action potential goes from the start to the end of an axon, it decays or becomes weaker, and it is the most common method of transmitting electrical signals in neurons. 2. It differs from the mode of propagation along the neuron, the action potential is actively propagated along the axon without decay.
A passive signal can be generated by a receptor or by a spike in the membrane potential of an adjacent neuron. In the neuron, an electrical current flows from the dendrite to the cell body, down the axon and into the terminal, causing a change in the potential across the membrane. The current also generates an electrical field that spreads throughout the surrounding tissue, this electrical field, known as the extracellular potential, decays with distance and is much smaller than the intracellular potential. So therefore a passive signal can be detected by electrodes placed outside the neuron.
An action potential is initiated at the axon hillock, propagated along the axon, and terminates at the presynaptic terminal. In the neuron, an electrical current flows from the dendrite to the cell body, down the axon and into the terminal, causing a change in the potential across the membrane.

define the term application and state three difficulties school-leavers may face when trying to apply for higher education
Answers
Answer:
Lack of funds
Entrance examination complications
Lack of ability to adjust
Explanation:
Three difficulties school-leavers may face when trying to apply for higher education are 1) unknown about streams 2) unknown about their ability 3) pressure under family and society.
Three difficulties school-leavers face to apply for higher education.Students, as they get pass out from the school, they face many problems to apply for higher education. The first problem come to our door which stream should we choose cause it decides our entire currier. What should we peruse, science, commerce or arts ?. Students don't know about what we will have to study in which streams. They just know profession and their corresponding stream, like if u want to become a doctor or engineer just take science, if u want CA, take commerce and take arts if u want to become a politician or economist. But they really don't know what we have to study in these streams. If they get to know what we have to study in which streams, they can take decision about choosing streams according to their area of interest.
Second thing student face problems while applying is they don't know about their ability and interest, Students take science or arts in spite of being excellent in arithmetic calculation. why because they want to become a doctor and they leave the course telling the reason of scissoring the body. It is like fish is trying to fly. Everyone has different ability and interest which we take from nature. We everyone have different gifts given by the God. If we know what we are excellent in, that will be helpful to choose our currier.
The third which is very very important problem facing by the students is they get under pressure of parents, they have to take engineering in spite of being excellent at another thing. After taking engineering they get more pressurized with the load of study. Non-interested engineering students don't enjoy their study. Many students get into depression and all. Students get pressurized by their parents to take admission in a particular stream because neighbor's son has taken admission for. Parents compare with salary associated with a profession, newborns. They don't get know about child's ability.
Hence these are important aspects which face students while applying for higher education.

________________________ The observable properties of an organism that are under genetic control.
Answers
The observable properties of an organism that are under genetic control are called phenotypes.
Phenotypes can include physical traits such as eye color, hair color, height, and weight, as well as behavioral traits such as intelligence, personality, and susceptibility to certain diseases. Phenotypes are determined by the interaction of an individual's genotype (genetic makeup) with environmental factors such as nutrition, exposure to toxins, and stress.
Phenotypes can be either continuous or discontinuous. Continuous phenotypes, such as height and weight, are controlled by multiple genes and exhibit a range of values. Discontinuous phenotypes, such as blood type and eye color, are controlled by a small number of genes and have distinct categories or types. Phenotypes can also be influenced by epigenetic factors, which can modify gene expression without changing the underlying DNA sequence. The study of phenotypes is important in fields such as genetics, evolutionary biology, and medicine.

a. from the mitochondrial matrix to the intermembrane space
b. from the intermembrane space to the mitochondrial matrix
c. from inside the mitochondria to the outside
d. from outside the mitochondria to the inside
e. NONE OF THESE
Answers
Electron flow down the electron-transport chain which leads to the transport of protons from mitochondrial matrix to the intermembrane space. Option A is correct.
During electron flow down the electron transport chain in mitochondria, protons (H⁺) are transported from the mitochondrial matrix to the intermembrane space. This process is known as proton pumping or proton translocation. As electrons pass through the electron transport chain, energy is released and used to pump protons across the inner mitochondrial membrane, from the matrix to the intermembrane space.
This creates an electrochemical gradient, with a higher concentration of protons in the intermembrane space compared to the matrix. This gradient is then utilized by ATP synthase to produce ATP through a process called oxidative phosphorylation.
Hence, A. is the correct option.

why does the lb/amp/ara plate fluoresce when the lb/amp plate does not
Answers
The lb/amp/ara plate fluoresces because it contains the ara gene whereas the lb/amp plate does not fluoresce due to the absence of the ara gene.
The ara or arabinose gene must be added to turn on the operon and make the E. coli glow. Green fluorescent protein (GFP) is a protein that glows with a bright green fluorescence and was first isolated from the marine jellyfish Aequorea victoria. Ara gene encodes the regulatory protein that binds to the pBAD promoter; the pBAD promoter binds arabinose and encourages RNA polymerase binding. When arabinose binds to the Ara gene, the production of GFP is switched on.
Because the second plate is the lb/amp plate there is no ara gene or arabinose, this hinders the binding of the RNA polymerase. As the RNA polymerase is not bound the green fluorescent protein or GFP will not be expressed. Thus the lb/amp plate also will not be showing any sort of fluorescence.

Do dead tree release carbon dioxide through cellular respiration
Answers
Absolutely, during cellular respiration, trees can emit carbon dioxide.
Cellular respiration is the mechanism through which living creatures, including trees, produce energy. A consequence of this process is the production of carbon dioxide as oxygen and glucose are digested to produce ATP, or energy.
By photosynthesis, trees take up carbon dioxide from the atmosphere and utilise it to make glucose. The glucose is broken down and carbon dioxide is released back into the atmosphere during cellular respiration. The environment's carbon dioxide and oxygen levels are balanced thanks to this mechanism.
In addition, a consequence of photosynthesis in trees is the release of oxygen. Some creatures utilise this oxygen later on for their own cellular respiration. Thus, trees are crucial in controlling the carbon cycle.

you have learned that during a solar eclipse the moon passes between the sun and the earth. During a lunar eclipse, the earth passes between the sun and the moon. In this experiment you will simulate both a solar and lunar eclipse.
These supplies are needed:
A large ball about the size of a basketball to represent the earth
A small ball about the size of a tennis ball to represent the moon
A strong light of about 100 watts or more
A method for darkening the room
Note: If your room is difficult to darken, you may use the sunshine as a source of light. You may also want to use cardboard circles in place of balls. Cut one large circle about 8 inches in diameter to represent planet earth. Label it earth. Cut one small circle about 3 inches in diameter. Label it moon.
Procedure:
1. Place the large ball (basketball) about 12 feet from the light source. Then, place the small ball (tennis ball) in the shadow of the large ball. If you are using cardboard circles in place of the balls, hold the large cardboard circle up in the sunshine. Then, place the moon (small cardboard circle) in earth's shadow. When you have lined up the balls or cardboard in this manner, you have made a shadow fall on the moon. This shadow represents an eclipse of the moon.
2. Now, shift the balls or cardboard to make the shadow fall on the basketball or largest cardboard. In effect, the sun is being darkened. If you were an observer on the earth, this condition would be a solar eclipse. When the moon comes between the sun and planet earth, a solar eclipse occurs.
The preceding illustration shows how an eclipse can be artificially made. The moon (tennis ball) is darkened by a shadow. This shadow represents a lunar eclipse (moon eclipse). You can reverse the position of the tennis ball and the basketball to represent a solar eclipse.

Explanation:
El proceso de nutrición consiste en la ingesta de alimentos, los cuales son posteriormente transformados en energía y estructuras celulares que el organismo necesita para funcionar normalmente. Durante este proceso, intervienen cuatro sistemas:
- Sistema digestivo: descompone químicamente los alimentos en nutrientes. Los alimentos son sometidos a un proceso de fragmentación mecánica y digestión química. En primer lugar, los alimentos son triturados en la boca por los dientes, mezclados con saliva para formar un bolo alimenticio que llega al estómago donde los jugos gástricos los transforman en una papilla conocida como quimo. A continuación, los nutrientes llegan al intestino delgado donde son mezclados con el jugo pancreático y la bilis del hígado para ser absorbidos por la sangre. Finalmente, los compuestos que no fueron absorbidos llegan al intestino grueso donde se absorbe lo que queda de agua y lo demás es eliminado.
- Sistema respiratorio: los pulmones son los órganos encargado del proceso de respiración mediante el cual el organismo intercambia gases con el ambiente a través la sangre. De este modo el organismo obtiene oxígeno que es utilizado para oxidar los nutrientes obtenidos por el sistema digestivo.
- Sistema circulatorio: encargado de transportar nutrientes y oxígeno a las células del cuerpo y simultáneamente transportar elementos de desecho hasta los órganos del sistema excretor.
- Sistema excretor: encargado de eliminar los desechos de los alimentos. Los compuestos que no fueron digeridos en el intestino delgado llegan al intestino grueso donde se transforman en las heces las cuales son expulsadas por el ano. Por otra parte, el aparato urinario formado por los riñones y la vejiga urinaria funcionan para eliminar los desechos de la sangre a través de la orina.

Plants living in regions where water supplies in the soil are low develop various adaptations to aid in their survival. Suggest FOUR of these adaptations.
Answers
Plants living in regions with limited water availability have evolved various adaptations to cope with the challenging conditions.
Four common adaptations seen in such plants:
1)Succulence: Many plants in arid regions have evolved succulent structures to store water.
These plants typically have fleshy leaves, stems, or roots that can store significant amounts of water during periods of rainfall.
The stored water can then be utilized during times of drought, allowing the plant to survive extended periods without rainfall.
2)Reduced leaves or spines: To minimize water loss through transpiration, plants in arid environments often have reduced leaves or modified leaf structures.
For example, some plants have small, needle-like leaves or spines that help reduce the surface area exposed to the hot and dry air, thereby reducing water loss.
3)Deep root systems: Plants adapted to arid conditions often possess deep root systems that enable them to access water from deeper soil layers.
These extensive root systems can tap into groundwater sources or reach areas with higher moisture content, allowing the plant to survive when surface water is scarce.
4)CAM photosynthesis: Crassulacean acid metabolism (CAM) is a specialized form of photosynthesis that many arid-adapted plants employ.
CAM plants open their stomata and take in carbon dioxide during the night when temperatures are cooler and water loss through transpiration is reduced.
They store the carbon dioxide as an organic acid and utilize it during the day for photosynthesis when the stomata remain closed to conserve water.
These adaptations enable plants to conserve and efficiently utilize water, enhancing their chances of survival in regions with low water supplies.
