What adaptations allow the same bacteria that live on Earth to live on the International Space Station (ISS)
In order to survive on the ISS, bacteria must be able to withstand the immense gravitational forces, exposure to radiation, lack of oxygen, and other environmental factors that are not present on Earth.
Fortunately, bacteria have evolved a variety of adaptations that allow them to survive and thrive in space.One of the most important adaptations for bacteria living on the ISS is the ability to survive in low-oxygen environments. The ISS has very low levels of oxygen, which are not conducive to most life forms. However, many bacteria have adapted to survive and reproduce in these conditions.
Bacteria have developed specialized metabolic pathways that enable them to use different sources of energy, such as carbon dioxide, sulphur, and nitrogen compounds, that are more abundant in the environment of the ISS than oxygen. This allows them to survive and reproduce in the low-oxygen environment of the ISS.
Bacteria have also developed the ability to tolerate the intense radiation exposure that is present on the ISS. Radiation can cause DNA damage and mutations, which can be fatal for bacteria. However, some bacteria have developed mechanisms to repair radiation-induced DNA damage, allowing them to survive and reproduce in the extreme environment of the ISS.

The structure of a water molecule results in hydrogen bonding due to the distribution of electrons in the molecule. Water molecules are made up of two hydrogen atoms bonded to a single oxygen atom, forming the chemical formula H2O.What is the hydrogen bonding about?The oxygen atom has a higher electronegativity than the hydrogen atoms, which means it is more effective at attracting and holding onto electrons. As a result, the oxygen atom has a partial negative charge and the hydrogen atoms have partial positive charges.
Therefore, a partial positive charges on the hydrogen atoms are attracted to the partial negative charge on the oxygen atom of another water molecule, forming a hydrogen bond. This is a weak chemical bond, but it is significant enough to give water many of its unique properties, such as its high surface tension and ability to act as a solvent.

Phenotype, a person's or a species' observable traits and attributes, is influenced by genotype. Depending on the trait, genetics can impact phenotypic to varying degrees. For instance, genotype alone determines the colour of a pea plant's petals. Depending on the alleles present, the pea plant's petals can be either purple or white. But the genotype has a very small impact on some traits. These traits are occasionally referred to as complex traits since they are impacted by a variety of variables, including environmental and epigenetic influences.

INTRO TO CELL RESPIRATION OVERVIEW POGIL: All cells need energy all the time, and their primary source of energy is ATP. The methods cells use to make ATP vary depending on the availability of oxygen and their biological make-up. In many cases the cells are in an oxygen-rich environment. For example, as you sit and read this sentence, you are breathing in oxygen, which is then carried throughout your body by red blood cells. But, some cells grow in environments without oxygen (yeast in wine-making or the bacteria that cause botulism in canned food), and occasionally animal cells must function without sufficient oxygen (as in running sprints). In this activity you will begin to look at the aerobic and anaerobic processes that are used by all organisms to produce ATP. Which statement is NOT true based on this intro
The products formed as a result of cellular respiration are ATP, water and carbon dioxide.
The cells require energy to perform all their cellular functions. The source of energy for them is ATP which is adenosine triphosphate. The amount of ATP which is produced by a cell depends on its requirement and also on the amount of oxygen that is available.
Depending on whether a particular organism requires oxygen or not, they can be classified as aerobic and anaerobic. Aerobic organisms are the ones which require oxygen whereas anaerobic organisms do not require oxygen. The reaction for cellular respiration can be represented as:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
Carbon dioxide, water and ATP are formed as products in this reaction.

How can a cell increase surface area without increasing the volume?
Cells can increase their surface area by folding the plasma membrane. Total cell surface area should increase when a cell divides into two daughter cells.
There are two illustration of membrane supply that support cell division:
(1) unfolding of small surface membrane reservoirs such as microvilli and folds, and (2) exocytosis of intracellular vesicles.
As the cell radius increases, the surface area increases as the radius squared, but the volume increases as the radius cubed (much faster).
Increasing the surface area of the cell increases the amount of material that diffuses into the cell. As volume and surface area increase, volume increases more rapidly, so for every doubling of cell volume, the surface area available for uptake is halved.

The urinary problem caused by interference with the normal nerve pathways associated with urination known as neurogenic bladder.
Neurogenic bladder is a urinary problem caused by interference with the normal nerve pathways associated with urination. It is a condition wherein the nerves connected to the bladder do not function properly, which leads to difficulty in controlling the bladder and emptying it properly. This can lead to a wide range of symptoms, including difficulty in starting urination, an inability to empty the bladder fully, incontinence, and urinary tract infections.
The primary cause of neurogenic bladder is usually damage to the nerves that control the bladder. This can be due to a variety of conditions, including traumatic brain or spinal cord injuries, multiple sclerosis, Parkinson’s disease, stroke, and diabetes. In some cases, the underlying cause is unknown.
The symptoms of neurogenic bladder are usually the result of an inability to control the flow of urine. This can lead to an overactive bladder, which can cause frequent urges to urinate, even when the bladder is not full.

The cell bursts when the cell wall of a plant cell is removed by a certain way, then put in distilled water because the cell wall is removed, the cell would get wet, which would cause it to burst..
How do plant cells react to exposure to distilled water?Putting a plant cell in distilled water causes it to become turgid. This is due to a process called osmosis, which causes the plant cell's cytoplasm to swell up and firmly press up against the cell wall as it absorbs water from the hypotonic distilled water.
