Living system can be defined as the internal systems of organisms and how materials circulate within organisms.

Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.

Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.

Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc., which are typically used for carrying out various bodily functions such as respiration, metabolism, digestion, etc.

A sensory system can be defined as components of the central nervous system (CNS) which comprises of the brain, neural tissues or pathways and sensory neurons responsible for sensory functions, perception and processing sensory informations such as sound, light, heat, etc.

Basically, the central nervous system (CNS) interprete the neural signals that are generated from stimuli that are detected by the sensory system. The five (5) main sense organs in the sensory system are: skin, tongue, ears, nose and the eyes.

Generally, the nervous system found in living organisms such as humans, comprises of two (2) major components or systems; a central nervous system (CNS) and a peripheral nervous system (PNS).

The correct sequential order for the transmission of a signal through the nervous system;

1. Nerve impulse is triggered.

2. Synaptic vesicles release neurotransmitters.

3. Neurotransmitters diffuse across synaptic cleft.

4. Receptors bind neurotransmitters.

5. The whole process is started all over again when the nerve impulse is triggered.

Legs are better for things such as walking, while it’s the oppostite for fins and tails. Those are better used for swimming. Early whales didn’t have tails and fins, so their skeletons adapted into fins and tails so they could move around better in the water since that is where they spent most of their time. In conclusion, skeletons generally adapt to a form that best suits the animal.

Explanation:

According to natural selection, early whales didn’t have tails and fins, so their skeletons adapted into fins and tails so they could move around better in the water.

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways.

There are four principles at work in evolution—variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection.

A typical gamete, sometimes referred to as a sex cell, should have half as many chromosomes as a typical body cell. The third daughter cell visible in the photograph appears to have an extra chromosome, making the total number of chromosomes there 47 rather than the typical 46.

In humans, gametes are haploid cells with 23 chromosomes—one of each chromosomal pair found in diplod cells—and are hence haploid. The haploid number, commonly known as n, is used to indicate the number of chromosomes in a single pair.

Gametes are haploid because they have half as many DNA bases as from the initial diploid germ cell's chromosomes. In other words, the secondary gametes only have one set (23), whereas the germ cell had two sets (46) of chromosomes.

A correct description of a color result would be the absence of blue coloration, indicating successful ligation and disruption of the lacZ gene.

The lacZ gene in the multiple cloning site of a vector is commonly used as a reporter gene in molecular biology experiments. It produces an enzyme called β-galactosidase, which can cleave a colorless substrate called X-Gal into a blue product. However, when the gene of interest is ligated into the multiple cloning site, it disrupts the lacZ gene, rendering it non-functional.

To screen for successful ligations, X-Gal is added to the system. If the lacZ gene has been disrupted by the gene of interest, β-galactosidase activity is lost, and the blue color is not produced. Therefore, a correct description of a color result would be the absence of blue coloration. This indicates that the lacZ gene has been disrupted, suggesting a successful ligation of the gene of interest into the vector.

This color-based screening method allows researchers to easily identify and select clones containing the desired gene of interest by visualizing the absence of blue color, providing a convenient and efficient way to screen for successful ligations in molecular cloning experiments.

A raindrop of almost pure water lands on a microbe. Mechanosensitive channels, activated by osmotic pressure, are used by microbes to reduce their internal solute concentration by letting solutes out.

In microorganisms, Mechanosensitive channels are very crucial as they play a significant role in different cellular functions. These channels are triggered by the difference in osmotic pressure in cells.

Different cellular functions performed by them include fluid homeostasis, transfer or expression of genetic information, cell adhesion, cell division, and migration.

Moreover, these channels also make a response to membrane tension by changing their conformation.

As these channels serve as a certain passage for different ions therefore they also activate various cells such as cochlear hair cells, sensory cells, and sensory neurons as a result of force applied to proteins.

The insertion or ending point is where the muscle attaches to the bone that it moves when it contracts and relaxes.

In skeletal muscle, the "insertion" is the point where the muscle attaches to the bone that it moves when it contracts and relaxes. Muscles work by contracting and relaxing, which causes movement of the bone or body part they are attached to. In order to do this, the muscle must be anchored to a stable point, called the "origin", and must attach to the bone that it moves, called the "insertion".

When the muscle contracts, it pulls on the insertion, causing movement at the joint. For example, the biceps muscle in the upper arm has its origin at the scapula and its insertion at the radius bone of the forearm. When the biceps muscle contracts, it pulls on the radius bone, causing flexion at the elbow joint. The insertion point can vary depending on the muscle and its function.

The covalent intermediate will occur through the nucleophilic substitution by the side chain carboxyl of Asp14 at the electrophilic phosphorus atom in the substrate, displacing a leaving group.

Nucleophilic substitution reaction is a class of organic reactions where one nucleophile replaces another where reactive element replaces a less reactive element from its salt solution. The group which takes electron pair and displaced from the carbon is known as “leaving group” and the molecule on which substitution takes place known as “substrate”. The leaving group leaves as a neutral molecule or anion.

Enriched experiences promote synaptic plasticity, leading to more dendritic spines and stronger neural connections, which contribute to cortical thickness. The increase in cortical thickness with enriched experience is most likely due to the increased size of synaptic junctions, the number of dendritic spines, and the branching of dendrites. The fluid content of cortical tissue may also play a role, but it is not as significant as the other factors.

By combining Flower B, which is homozygous dominant for the purple trait (BB), and Flower D, which is homozygous dominant (DD), both flowers carry the dominant allele for purple, the concepts of homozygosity and Punnett squares may be better understood.

Thus, if flower B exclusively possesses the dominant allele for purple, it is said to be homozygous dominant for the purple characteristic (BB). Similarly, flower D has the dominant allele for purple if it is homozygous dominant (DD).

A heterozygous genotype (BD) for the purple trait is produced when these two homozygous parents (BB x DD) are crossed. This genotype results from all the kids inheriting one allele for purple from each parent. Therefore, neither flower B nor D could possibly be homozygous dominant for the purple trait in the first-generation offspring.
