Stem cells are so desirable because they can effectively be used for replacement of diseased cells with the healthy ones.
Stem cells generate healthy cells to replace diseased cells and therefore, are regarded as regenerative medicines. Stem cells can be directed to become specific cells that can be used in humans to regenerate and repair tissues damaged or affected by disease. This is why they are so desirable. They also help us to better understand about how diseases occur.
Stem cells are the raw materials of the body, the cells that give rise to all other cells with specialized functions. Under the right conditions, stem cells divide to form more cells known as daughter cells in the body or in a laboratory. These daughter cells either differentiate into new stem cells or become specialised cells with a more specific function, such as blood cells, brain cells, heart muscle cells, or bone cells. No other cell in the body has the ability to naturally generate new cell types.

A member of one species (the predator) feeds directly on all or part of a living organism (the prey) as part of the food web.
Predation is the act of one species' (the predator's) member eating all or a portion of another species' living or recently living body.
When two organisms interact, it's called predation. The predator eats all or a portion of the prey's body. A type of predation called herbivory uses a plant as the prey organism. Population dynamics of the predator and prey have an impact on one another.
Predation occurs when a member of one species—the predator—eats the entire living or recently living body of another species—the prey. The prey suffers negative consequences as a result of this contact, which is positive for the predator. One organism kills and eats another in a predation situation. For an organism to live longer and encourage reproduction, it needs energy from predation.

fragments of copied dna created on the lagging strand
Okazaki fragments are short fragments of DNA that are created on the lagging strand during DNA replication.
DNA replication occurs in a semi-conservative manner, with each strand of the original double helix serving as a template for the new strand. The lagging strand is duplicated in intermittent chunks known as Okazaki fragments, whereas the leading strand is repeated constantly. These fragments are then joined together by the enzyme DNA ligase, creating a continuous strand of DNA that is identical to the original template strand.
This process of creating Okazaki fragments and joining them is known as lagging-strand synthesis and is essential for accurately replicating DNA. Without lagging-strand synthesis, mutations would accumulate and the cell would be unable to replicate its genetic information accurately.

https://brainly.com/question/16099437
#SPJ4
Fragments of copied DNA created on the lagging strand are called Okazaki fragments.
During DNA replication, the double helix structure of DNA must be unwound and separated in order for new strands to be synthesized. This process is carried out by a group of enzymes called helicases, which unwind the double helix and create replication forks at the point where replication begins.
One of the strands, called the leading strand, is replicated continuously in the 5' to 3' direction, which is the same direction as the replication fork moves. However, the other strand, called the lagging strand, is replicated in the opposite direction in short fragments, because it runs opposite to the direction of replication. These fragments, called Okazaki fragments, are typically around 100-200 nucleotides long, and are formed by the action of the enzyme DNA polymerase.
As the replication fork moves along the DNA, the enzyme DNA polymerase moves along the leading strand and continuously adds nucleotides to the 3' end. However, on the lagging strand, DNA polymerase can only add nucleotides in the 5' to 3' direction for a short distance before it reaches the end of the strand. So, every time the polymerase reaches the end of the strand, it has to detach and reattach to the next replication fork, creating a new Okazaki fragment.
Once all the Okazaki fragments have been synthesized, they are joined together by the enzyme DNA ligase to form a continuous strand. This process is known as Okazaki fragment ligation. Okazaki fragments are important in DNA replication as they ensure the accuracy and integrity of the newly synthesized.

Synaptic integration is the process by which multiple synaptic potentials combine within one postsynaptic neuron. It is a mechanism through which neural information is processed and transmitted.
In the process of synaptic integration, the postsynaptic neuron receives inputs from multiple presynaptic neurons. These inputs are in the form of excitatory postsynaptic potentials (EPSPs) and inhibitory postsynaptic potentials (IPSPs). EPSPs are positive potentials that tend to depolarize the postsynaptic neuron, while IPSPs are negative potentials that tend to hyperpolarize it.
The postsynaptic neuron then combines these inputs, by adding together all EPSPs and IPSPs generated by different presynaptic neurons. The resulting synaptic potentials are then used to determine whether the postsynaptic neuron will fire an action potential or not. Synaptic integration is an essential process in the neural communication and it helps to transmit the complex information between neurons.

Why do scientists think that the current global warming situation is NOT caused by natural forces?
Scientists believe that the current global warming situation is not caused by natural forces due to the sheer magnitude and speed of the warming.
In the past, natural climate events, such as the Medieval Warm Period and the Little Ice Age, have caused climate changes but these climate changes have been much slower than the current global warming trend. Natural climate events also tend to be more regional in nature, while current global warming is observed across the entire globe.
Furthermore, the current rate of global warming is much faster than any natural climate event in recorded history. This is largely due to the emission of large amounts of greenhouse gases, such as carbon dioxide and methane, by human activities.
Scientists have identified a clear correlation between the increasing levels of these human-emitted gases and the rising global temperatures.Therefore, according to the majority of experts, human actions are mostly to blame for the current state of global warming.

a random base change is less likely to affect phenotype in humans than in bacteria. why? please select all that apply.
Due to lesser junk DNA the random mutation is going to affect the bacteria more than the human in case of phenotype.
For a few reasons, phenotype (an individual's observable features or qualities) is less likely to be impacted by a random base change, or mutation, in human DNA than in bacterial DNA. The human genome is significantly bigger and more complicated than the bacterial genome, which is one explanation.
This implies that the human genome contains more base pairs and that the relationships between genes and other DNA sequences are more complex. Human cells also have a more advanced method for mending DNA damage, which aids in preventing mutations. Furthermore, whereas bacteria reproduce quickly, allowing them to quickly adjust to changes in their environment, natural selection tends to pick out deleterious mutations in humans.

Mitosis is divided into several stages or phases of the cell cycle, such as interphase, prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis, which are necessary to successfully make the new diploid cells. During mitosis, the chromosomes in the nucleus duplicate, and then align at the center of the cell before separating into the two new daughter cells.
It's important to note that there is another type of cell division called meiosis, which results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores. Meiosis occurs in diploid cells. The chromosomes duplicate once, and through two successive divisions, four haploid cells are produced, each with half the number of chromosomes as the parent cell.
In summary, Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth. Meiosis is a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores. Both types of cell division occur in diploid cells but with different outcome in terms of chromosome number in the daughter cells.

which classes of neurons are most likely to repair themselves after damage? a. afferent neurons b. efferent neurons c. interneurons d. a and b e. a, b and c
The correct option is D; a and b , In most cases, nerve cells in the central nervous system do not renew. However, in reaction to an injury, this component of the nervous system might restructure.
This is referred to as "plasticity." Fortunately, the brain has a lot of redundancy built in.
Pressure, stretching, or cutting can all cause neuron injury. An lesion to a neuron can disrupt the transmission of impulses to and from the brain, resulting in muscular weakness or lack of sensation in the afflicted region. Nerve injuries can have an effect on the brain, spinal cord, and peripheral nerves.
Unfortunately, because to the intricacy of the brain and spinal cord, there is very little spontaneous regeneration, repair, or healing.

which of the statements about hemoglobin and myoglobin structure are true? both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron (fe) ( fe ) atom. hemoglobin and myoglobin are heterotetramers. each hemoglobin molecule can bind four oxygen molecules and each myoglobin can bind only one oxygen molecule. the heme prosthetic group is located in a hydrophobic cleft in the protein, with propionate (propanoate) groups exposed at the surface. each iron atom can form six coordination bonds and one of these bonds is formed between iron and oxygen. molecular oxygen binds irreversibly to fe2 fe 2 in heme. by itself, heme is not a good oxygen carrier. it must be part of a larger protein to prevent oxidation of the iron.
Five statements about the structure of hemoglobin and myoglobin are correct: - 1:- Both hemoglobin and myoglobin contain a prosthetic group known as heme.
which contains a central iron atom, which is a true statement because iron atoms can bind with one oxygen molecule. As a result, this statement is correct.
The equilibrium between oxyhemoglobin (oxygen-bound hemoglobin) and hemoglobin (free of oxygen molecules). Each molecule of hemoglobin can bind up to four oxygen molecules at the same time; this occurs through cooperative binding, which means that increased hemoglobin-oxygen binding at the protein hemoglobin's subunits (where oxygen is a ligand) increases its affinity for oxygen.
This is because the altered orientation of the protein's secondary structures causes a conformational change in the hemoglobin molecule, making it easier for a second molecule of oxygen to be followed by more O2-Haem binding until the molecule is saturated. However, because myoglobin only has one Hem subunit, it can only bind to one molecule of oxygen. while hemoglobin has the ability to bind four.
