A reaction is called spontaneous when it takes place of its own accord without any external help. It is an exothermic reaction and it is a spontaneous reaction . Above examples show, both exothermic and endothermic reactions could be spontaneous.

There are various types of chemical reactions based on the properties of the reactant. Exergonic reactions are chemical reactions that tend to happen spontaneously.

Exergonic reactions are defined as chemical reactions that show spontaneous nature and releases energy out into the surrounding. The reactants form a stronger bond when they are joined instead of when the bonds are broken.

In a biological system, the exergonic reactions occur when glucose is broken down into waste and carbon dioxide during the cellular respiration step. This released amount of energy is used by the cells to function and plays various roles.

Therefore, exergonic chemical reactions are spontaneous reaction that tends to occur on their own.

Answer:

Neon's outer energy level contains eight electrons.

Explanation:

Energy level defined as the different areas for an electron present in an atom.

The Neon atom contains two electrons in energy level I and the remaining eight electrons present in energy level II (which can hold only 8 electrons). This means that the outer energy level is full so that a neon atom is very stable.

Photosynthesis is a process by which plants use sunlight, water, and carbon dioxide to produce carbohydrates, and other biological compounds, which reduces the amount of carbon dioxide in the air. This is the difference between plants and animals. The carbon dioxide is stored in the plants until they decompose or are burned. So, for example, each fall when the trees lose their leaves and the plants die the level of carbon in the atmosphere goes up. The rest of the tree, bark etc., does not continue to absorb carbon. Plants only take in carbon so long as they are growing and not after they have reached their natural height. Planting trees and other plants is one component of the solution to global warming, but the number of plants we have now cannot consume more carbon than they already do, and there is some evidence that warmer temperatures make photosynthesis more difficult.

B.Proteins produced by cells have structures that are related to their function.

Explanation

Haemoglobin contains 4 polypeptide chains.In adults,they have 2alpha (a) globin chains and 2 beta (b) globin chains.Each polypeptide has a haem prosthetic group attached.A single haem bids one oxygen molecule.The 4 haemoglobin groups in every molecule of haemoglobin binds 4 oxygen molecules.

The information provided best demonstrates that the proteins produced by cells have structures that are related to their function. So the correct option is B.

In this case, the protein hemoglobin has a specific structure that allows it to bind to oxygen and transport it throughout the body, which is directly related to its function.

This illustrates the concept of structure-function relationships in proteins. While the other statements may also be relevant in a broader context, they are not directly demonstrated by the information about hemoglobin and its function.

Then we can see that the correct option is B.

The answer is fresh snow

Answer:

The correct answer is fresh snow.

Explanation:

The albedo refers to the measurement of reflectivity. It is the amount of the reflection getting diffused of the solar radiation out of the entire solar radiation getting by an astronomical body, like a planet Earth. It is determined on a scale from 0 to 1 and is dimensionless.  

Of the mentioned options, the formation of fresh snow on the top ground covering demonstrates the greatest reflectivity, thus, the albedo measurement would be the greatest here.  

The oceans on early Earth formed as the planet cooled and volcanic activity released gases through outgassing. Water vapor in the atmosphere condensed and created rain, which filled basins to form primitive oceans. Additional water from space may have contributed to this process.

Approximately 4.6 billion years ago, when Earth formed, it was a molten world without an atmosphere or oceans. Over time, Earth's early, hot surface began to cool, allowing for a solid crust to form. As the climate continued to cool and the crust solidified, volcanic activity was prevalent, emitting various gases, a process known as outgassing. The outgassed water vapor, along with gases like carbon dioxide (CO2) and methane (CH4), started to build Earth's early atmosphere.

Eventually, as the atmosphere cooled further, the water vapor started to condense, and Earth experienced its first rainfall. This condensation and the subsequent precipitation were crucial steps in the formation of Earth's oceans. Additional water is theorized to have been delivered by comets and asteroids striking the planet.

Over millions of years, and as the surface temperature dropped, persistent rainfall filled basins and low areas, forming the primitive oceans. The atmosphere, once hostile and rich in reducing gases like methane and ammonia, began to transform as the Earth evolved towards supporting life as we know it today.

By about 3.8 billion years ago, enough cooling had occurred to allow rainwater to stay liquid and not vaporize upon contact with the Earth's surface. Thus, the early warm, shallow oceans were formed in a reducing environment with little oxygen. Later tectonic activity would reshape these primitive oceans into the complex distribution of seas and continents present on modern Earth.

The right order is

1. A receptor detects a signal

The stimulus (ie the external signal), by its action on the sensitive area of the sensory receptor called transducer site, creates a variation of potential whose course and amplitude depend on the stimulus.

This variation of potential constitutes the receiver potential.

This conversion of the stimulus into a receptor potential, called transduction, is related to changes in the permeability of the receptor cell membrane.

2. The sensory nerves sends a signal to spinal cord .

Sensory information is detected by peripheral sensory receptors and then transmitted to the central nervous system via sensory neurons, otherwise known as afferent fibers. These sensory neurons have a particular morphology, they are called "T" neurons because the single dendrite and the axon that emerge are contiguous to the cell body, located in the ganglion, then separate to connect the sensory receptor d one side, and the nerve center of the other.

3. The relay neuron sends a signal to motor nerves .

The motor nerves carry motor control from the central nervous system to the effectors that are mainly the muscles. These efferent nerve fibers originate in the central nervous system: the spinal cord and the motor brain centers. Efferent fibers emerge from the spinal cord through the ventral root of the ventral horn. From the spinal cord are motor neurons γ, which contact the neuromuscular spindle.

4. A muscle receives a signal to contract .

The neuromuscular spindle is a mechanoreceptor composed of modified muscle fibers. Arranged parallel to the muscle fibers, it is sensitive to the lengthening of the muscle, and translates a mechanical stimulus into a nervous message.

These spindles are sensory receptors. They therefore play an important role in static proprioception, as well as in kinesthesia.

They are also involved in the myotatic reflex: their role is then to increase the level of contraction of the muscle in response to its own stretching. The muscle tends to return to its original length.

5. A bone moves.

Muscular movement is based on the ability of a living structure to exert a force by shortening itself. Which requires:

* a contractile structure: the muscle

* a support structure (to be able to exert a force): the skeleton (bones and joints) and the tendons by which the muscles are attached to it

* a control system (the nervous system) and a control system (the nervous system or the immune system that act by chemical mediators (hormones, neurotransmitters ...) and adaptation (response to environmental stimuli) essentially comprising receptors (organs of internal and external perception) connected to the control nerve centers (brain).

Man uses the muscular force developed by his muscles that rely on a skeleton to perform movements under the control and control of the nervous system and organs of perception. put apart the reflexes, he can also use the movements of his limbs resting on the ground or water to move his whole body (walking, running, swimming ....).

A reflex begins when a receptor detects a signal, which sends an impulse via a sensory neuron to the spinal cord. It is then transferred to a motor neuron via a relay neuron, which leads to a muscle or gland reacting. If the reaction is a muscle contraction, it may cause a movement, such as the movement of a bone.

A reflex is an automatic, involuntary response to a stimulus. The correct order of steps that describe how a reflex occurs are as follows:

Organic(Ordinary) leaves are grown on trees organically by water(Dew) and temperature. 1 difference between Sessile and Ordinany leaves is the time of year when they fall off.

I'll give you a hint for the rest, Do sessile fall? Do Ordinany leaves fall? Do both? Do neither?

The main difference between sessile and ordinary leave is petiole.

Sessile leaves lack sessile while ordinary leaves have a petiole. In botany, sessility (meaning "sitting", used in the sense of "resting on the surface") is a characteristic of plant parts that have no stalk. Flowers or leaves are attached directly from the stem or peduncle, and thus Sessile leaves lack a lack a petiole or pedicel. The leaves of the vast majority of monocotyledons lack petioles.

Plankton grows in the Sunlit Zone. It is also know as the euphotic zone. There is enough light going in the water to support photosynthesis. Because of photosynthesis, more than 90 percent of all marine life lives in this zone.

Physical weathering, also known as disaggregation or mechanical weathering, refers to the category of procedures, which makes the disintegration of rocks in the absence of chemical modification. In general, the mechanical weathering takes place due to the build-up of pressure within the rocks.  

However, the rocks can also get worn away by a procedure known as abrasion. Abrasion refers to the disintegration of rocks due to friction.  

The abrasion is a form of mechanical weathering apex.

The correct answer is the application of the coarse adjustment to focus the specimen under high power.  

One should always remember while using the coarse adjustment to focus the microscope is to use it only with the low power objective. One should prevent the use of coarse adjustment when focusing on high power because the image moves in and out of focus too prompt that it becomes tough to accurately adjust the focus.  

Secondly, one may run the threat of crashing the objective into the slide, that is, why it is recommended to use the coarse focus only with the 4x low power objective. However, one can use the fine focus knob with all the objectives.

Improper cleaning of lenses, carelessly adjusting the focus and objective, misuse of immersion oil, and not securing the microscope when not in use can lead to microscope and specimen damage.

There are several activities that could potentially lead to damage of a microscope and specimen. These include activities such as not cleaning the lenses with lens paper, allowing the lens to come into contact with the slide by rapidly changing the focus, pushing an objective into a slide, and using the coarse focusing knob when using the 40× or greater objective lenses. Moreover, only using immersion oil with a specialized oil objective, generally the 100× objective and cleaning oil from immersion lenses after using the microscope is critical.

Damage may also come from negligence when a microscope is not being used, such as not covering it or placing it in a cabinet. Looking at a specimen, if the slide with the specimen is not properly secured and centered over the light, damage may occur. It is crucial to take the utmost care when using a microscope and handling specimens to avoid any damage that may affect the accuracy of your observations and study.

The lymphatic system is open, in contrast to the circulatory system, which is a closed system. An average of 20 liters of blood are processed by the human circulatory system each day through capillary filtration, which purges the blood of plasma. Three liters of the filtered blood are left in the interstitial fluid, while around 17 litres are reabsorbed into the blood arteries. The lymphatic system's primary job is to give the extra three litres of blood a secondary return pathway to the blood.

Immune defense is the other primary purpose. In that it contains germs, proteins, and cellular waste along with waste products and cellular debris, lymph is remarkably similar to blood plasma. Most of the lymph's cells are lymphocytes. Associated lymphoid organs are made of lymphoid tissue and serve as either the loci for producing or activating lymphocytes.

Explanation:

Burning fossil fuels leads to C) increased carbon dioxide in seawater, causing ocean acidification and weakening corals.

The right response is C. Ocean acidification and coral deterioration would result from elevated carbon dioxide levels in saltwater. Carbon dioxide (CO2) is released into the atmosphere when fossil fuels are burned, and it can subsequently dissolve in seawater. Ocean acidification, a phenomenon caused by this dissolved CO2, is the process of increasing the acidity of the saltwater. Marine animals are badly impacted by ocean acidification, especially those with calcium carbonate skeletons or shells, like corals.
