What similarities and differences do prokaryotes have with modern-day green plants?
The cells of prokaryotes and plants have different constitutions, and some similarities, because their cell class is different, but they belong to the same evolutionary line, for a better answer, we must understand....
Prokaryotic cellsProkaryotic or prokaryotic cells, also called protocells, are very different from eukaryotes (plants). Its main feature is the absence of cariotheca individualizing the cell nucleus, due to the absence of some organelles and the small size that is believed to be due to the fact that they do not have membranous compartments originated by evagination or invagination. They also have DNA in the form of a non-protein-associated ring (as in eukaryotic cells, in which the DNA is arranged in coiled strands and associated with histones).
To this group belong unicellular or colonial beings:
Bacteria Cyanophytes (cyanophyte algae, blue algae or even Cyanobacteria) PPLO ("pleuro-pneumonia like organisms") or MycoplasmasEukaryotic cells (plants)Eukaryotic or eukaryotic cells, also called eucells, are more complex than prokaryotes.

Suggest two ways that reflex reactions help maintain homoeostasis in the human body.
Final answer:
Reflex reactions help maintain homeostasis in the human body by regulating functions such as heart rate and pupil size through the autonomic nervous system. The sympathetic and parasympathetic systems create a balance by providing opposing actions that respond to different environmental stimuli, essential for health and stability.
Explanation:
How Reflex Reactions Maintain Homeostasis
Homeostasis is the stable state of internal conditions in the human body. Reflex reactions play a critical role in this process. For instance, the autonomic nervous system manages involuntary functions such as heart rate and pupil dilation through the sympathetic and parasympathetic systems. These systems often act in opposition to create a balance, or homeostatic state.
Regulation of heart rate: The parasympathetic system reduces heart rate by slowing it down during rest, while the sympathetic system can increase heart rate during stress or activity, helping to provide more oxygen to tissues when needed.
Regulation of pupil size: Similarly, the sympathetic system dilates the pupils to let in more light and enhance vision under certain conditions, whereas the parasympathetic system constricts the pupils in bright light to protect the retina and maintain optimal vision.
These actions ensure that critical bodily functions are maintained within a narrow range of operation, which is essential for overall health and stability of the body's internal environment.
How does the arrangement of atoms and bonds change
The arrangement of atoms and bonds within molecules, especially in cases of isomers, substantially affects their properties. Different bonding processes, both ionic and covalent, induce energy changes which give rise to these unique properties.
Explanation:The arrangement of atoms and chemical bonds within molecules fundamentally changes their properties. This is exhibited in isomers, molecules that have the same chemical formula but differ in the placement of their atoms and/or bonds.
For instance, structural isomers like butane and isobutane have the same number of carbon and hydrogen atoms (C4H₁0). However, their different arrangements lead to significant variations in properties where butane is more suited as a fuel and isobutane as a refrigerant.
The basis of these variations stems from the two main types of bonds, ionic and covalent, where the former represents a transfer of electron from one atom to another, and the latter represents a sharing of electrons. The energy changes in these bonding processes are what mainly contributes to different characteristics of molecules.

The cell membrane is also known as a selectively permeable membrane because it allows selective substance to move inside the cell. It also helps in the recognition of certain chemicals.
Further Explanation:
The plasma membrane is the outermost layer of the cell. It forms the boundary between the intracellular and extracellular components. The main components of the plasma membrane are phospholipids, proteins, and carbohydrates. The phospholipids are arranged in a double-layer structure in which the head is present on the outside (water-loving) and the tail part is present inside the cell (water-hating). Proteins are present between phospholipids bilayer. These transmembrane proteins allow the molecules that could not enter the cell directly. The molecules pass by forming the channels, pores or gates. It also plays an important role in cell recognition, signaling and enzymatic activity. Carbohydrates are also present in the membrane, most of its part is found as glycoprotein. It helps in cell adhesion (cell attach to each other).
The functions of the cell membrane are:
1. It acts as a physical barrier: it physically separates the cytoplasm that makes up the cell from the extracellular fluid. It also allows separate activity to occur inside and outside the cell.
2. It allows selective permeability. The certain molecules can through them. Water, oxygen and carbon dioxide can easily move through the membrane. It does not allow ions such as potassium and sodium and other polar molecules to pass through them.
3. It also helps in facilitating the communication and signaling between cells.

Expectations for a herniated lumbar disk include pain and muscle weakness due to spinal nerve compression from the protrusion of the nucleus pulposus after the weakening of the anulus fibrosus.
Expected assessment findings for a herniated lumbar disk include pain and/or muscle weakness in the corresponding body regions supplied by the affected spinal nerve. Specifically, for a lumbar herniation, patients might present with sciatica, characterized by pain radiating from the lower back down the thigh and into the leg. The herniation occurs due to a weakening of the anulus fibrosus, leading to protrusion of the nucleus pulposus and subsequent nerve compression. Lifting a heavy object further increases pressure on the disk, exacerbating the protrusion and potentially increasing pain and dysfunction.
One way the body fights invaders is by increasing the body temperature, or running a fever. Give a brief explanation as to why that defensive technique works against some viruses or bacteria.
This is a writing assignment!
Some bacteria are not able to function properly and replicate at the fever-high temperatures hence this reduces their infection rates in the body. More research has also shown that the temporal increase in body temperature, during the fever, increases the activity of the cytotoxic T-cells that are significant in fighting infection.
In this exercise we have to explain how our body tries to fight bacteria and viruses just by increasing the temperature.
What is fever?Fever is not a disease in itself, it is usually the manifestation of some illness. Fever is characterized as an increase in temperature above normal levels.
So as explained, the answer will be our body's response so that bacteria can't multiply and thus destroy us from the inside. Leaving the environment with high temperatures and not conducive to its development.

After a period of prolonged fasting (starving), the brain changes its fuel requirements ________.
Final answer:
During prolonged fasting, the brain transitions from using glucose to using ketone bodies as the primary energy source due to depletion of glycogen stores and limited carbohydrate availability.
Explanation:
After a period of prolonged fasting (starving), the brain changes its fuel requirements from primary glucose to an increased reliance on ketone bodies as an alternative fuel source. Initially, in the absence of food, the body utilizes glycogen reserves, which are converted into glucose. However, when these stores are depleted, the body begins to metabolize fatty acids and proteins. Muscles switch from using glucose to fat-derived ketones to conserve protein and maintain glucose for the brain and other vital organs. Over time, as fasting continues and carbohydrate sources are limited, the brain starts to utilize ketone bodies more efficiently, which become the main energy source during prolonged starvation.

What is an unintended consequence of urban growth
An unintended consequence of urban growth is the degradation of the natural environment, leading to deforestation, pollution, and loss of biodiversity. The challenge is to manage such growth in a way that maximizes socio-economic benefits while minimizing negative impacts.
Explanation:An unintended consequence of urban growth, or urbanization, is the significant impact it can have on the environment and community values. For instance, the urban migration patterns and economic forces that drive city growth often lead to the degradation of the natural environment. This is seen in the changes to ecosystems, the increase in greenhouse gas emissions, and the depletion of natural resources.
Such growth also disrupts local communities, eroding traditional values and increasing feelings of loneliness and indifference. It has been observed that as economies develop, a larger proportion of their population starts living in urban areas.
In modern times, about 80% of the US population resides in metropolitan areas, a dramatic increase from just 40% in 1900. However, in less economically developed regions like parts of Africa, the urban population proportion is only around 30%. The challenge for such locales is managing urban growth to prevent the negative ramifications while reaping the socio-economic benefits.
