Mitochondria are membrane-bound organelles in eukaryotic cells that generate energy for the cell's metabolic activities.

Mitochondria evolved from a free-living bacterium that was engulfed by an ancestral eukaryotic cell around 1.5 billion years ago. A team of researchers investigated the evolutionary history of mitochondria and how they came to be so distinct from the bacteria that gave rise to them. They compared mitochondrial genomes to bacterial genomes and examined the origins of various mitochondrial genes.

One plant mitochondrion and five bacterial species were included in the comparison matrix because of the following reasons:

1. Because mitochondria are believed to have evolved from free-living bacteria, comparing mitochondrial genomes to bacterial genomes is a good way to see how mitochondria have evolved over time.

2. The plant mitochondrion and five bacterial species were chosen because they represent different branches of the bacterial tree of life. This allowed the researchers to see how mitochondrial genomes evolved in relation to different bacterial lineages.3. Comparing mitochondrial genomes to bacterial genomes also allows researchers to identify which genes were lost or gained during the course of evolution. This can help shed light on the functions of various mitochondrial genes and how they contribute to the overall function of the organelle.

Answer:

In a transverse wave, the particles of the medium move perpendicular to the direction of the wave. In other words, as the wave travels through the medium, the particles of the medium vibrate back and forth at right angles to the direction in which the wave is traveling.

Examples of transverse waves include light waves, radio waves, and microwaves. These types of waves are characterized by the oscillation of their electric and magnetic fields, which cause the particles of the medium through which they travel (such as air or water) to vibrate in a transverse motion.

In contrast, in a longitudinal wave, the particles of the medium move parallel to the direction of the wave. Examples of longitudinal waves include sound waves and seismic waves. These types of waves are characterized by the compression and rarefaction of the medium through which they travel, as the particles of the medium are displaced in the same direction as the wave.

Many cells of the neural tube have lost their pluripotency, and their fates have become a. totally specified.

During the development of the nervous system, cells in the neural tube become progressively more specialized and their developmental fate becomes more restricted. Initially, the cells of the neural tube are pluripotent, meaning they have the potential to differentiate into multiple different cell types. However, as development proceeds, the cells become more restricted in their fate and their differentiation becomes more specified.

By the time the neural tube has formed, most of the cells have lost their pluripotency and their fates have become totally specified. This means that each cell has been assigned a specific developmental fate and will differentiate into a particular type of neuron or glial cell. The specification of cell fate is driven by a complex interplay of genetic and environmental cues that act on the developing cells of the neural tube.

Living organisms convert this chemical energy into a specific type of kinetic energy called mechanical energy during activities such as walking or digesting food. All living organisms require energy to live and function. In general, they use chemical energy stored in food to create adenosine triphosphate (ATP), which is a form of chemical energy that cells use to power their functions.

ATP fuels almost all cellular activities such as nerve impulses, muscle contractions, and biosynthesis of macromolecules. Living organisms like humans use ATP to perform daily activities such as walking, running, digestion, and even breathing. When humans eat food, their body breaks it down into small molecules, and enzymes in their body convert these molecules into ATP in a process called cellular respiration. Mechanical energy is the energy of an object in motion, and kinetic energy is the energy of motion. Walking and digestion are activities that involve motion, and the movement of our muscles is an example of mechanical energy.

In summary, living organisms convert chemical energy into ATP, and ATP powers their functions, which involve the conversion of ATP into mechanical energy, which enables motion.

The sympathetic nervous system is associated with emotional and physical arousal.

In response to stress, danger, or arousal, the sympathetic nervous system, which is a part of the autonomic nervous system, sets off physiological responses like the "fight-or-flight" response. Stress hormones adrenaline and noradrenaline, which increase heart rate, blood pressure, pupil dilation, breathing rate, and alertness, are created.

These physiological adjustments prepare the body for powerful reactions to challenging circumstances. The sympathetic nervous system is important in both physical and emotional arousal. It also helps the body respond to stimuli and adapt to its surroundings.

Photosynthesis is similar to cellular respiration in the sense that the equation of one is the reverse of the equation of the other.

The original source of energy that is introduced into the ecosystem comes from the sun. This energy is passed along the food chain.

The equation that models cellular respiration is the equation; C6H12O6 + 6O2 → 6H2O + 6CO2 + Energy. Recall that cellular respiration involves the breakdown of glucose in the presence of oxygen. The compound that is involved in cellular respiration is oxygen.

The Calvin cycle is the light-independent (does not need light) step of photosynthesis and happens in the stroma.

The products of photosynthesis are carbon dioxide and water as we can see from the reaction; 6CO2 + 6H2O → C6H12O6 + 6O2.

Electrolysis does not form a part of cellular respiration. Glycolysis,  electron transport chain and the Krebs cycle are steps of cellular respiration.

The events shown in the picture occurs in the chloroplasts. The image shown the biochemical processes involved in photosynthesis.

During cellular respiration, glucose is split into its constituent molecules which are water and carbon dioxide when it reacts with oxygen.

The equation of photosynthesis is the reverse of the equation of cellular respiration.

Tetanic tension is much greater than twitch tension due to the differences in their underlying physiological processes and the frequency of muscle stimulation.

Twitch tension refers to the force generated by a single muscle contraction in response to a single, brief stimulus. It is a short and quick response, which does not allow the muscle fibers to fully develop their force-generating capacity.

In contrast, tetanic tension occurs when a muscle is stimulated at a higher frequency, causing a series of rapid, repeated contractions. This results in summation, where the force generated by each subsequent contraction is added to the force of the previous contractions. As a result, the muscle fibers are able to produce more force in total than they could during a single twitch contraction.

Additionally, during tetanic tension, the muscle experiences a sustained period of calcium influx. This increased calcium concentration allows for more cross-bridge cycling between actin and myosin filaments, resulting in higher force production. Moreover, the repeated stimulation prevents the muscle fibers from fully relaxing between contractions, allowing them to maintain a higher level of tension.

In summary, tetanic tension is much greater than twitch tension because of the summation effect, the sustained calcium influx, and the increased cross-bridge cycling. These factors allow muscles to generate a significantly higher force during tetanic contractions compared to a single twitch contraction.
