Photodecomposition, photomutagenicity and photocytotoxicity of retinyl palmitate under He-Ne laser photoirradiation and its effects on photodynamic therapy of cancer cells in vitro
The effects on photodynamic therapy of cancer cells in vitro is that retinyl palmitate (RP) can be used 24 h before PDT to enhance its effects. RP is not mutagenic under irradiation with He–Ne laser.
HeLa cells with or without RP (retinyl palmitate) that was incubated with the cells for a short or long incubation period prior to PDT are typically used to test the effects of PDT (photodynamic therapy) using hematoporphyrin derivatives (HpD) as photosensitizer under He-Ne laser irradiation.
No photodecomposition of RP alone is visible, but a small amount is seen of in the presence of HpD under He-Ne laser irradiation is seen. No photomutagenicity is often seen under laser irradiation. HeLa cell viability can be dramatically reduced by RP alone. A 24 hour incubation period before PDT increased the cytotoxicity of PDT on HeLa cells.
Therefore, retinyl palmitate (RP) can be used 24 h before PDT to enhance its effects. RP is not mutagenic under irradiation with He–Ne laser.

______ are geologic considerations when identifying physically safe places for human habitation.
The strength of the underlying geology, steepness of hillsides and faults in the Earth's crust which can potentially cause earthquakes are the geologic considerations during the identification of physically safe places for human habitation.
Geology basically deals with the study of the Earth and it finds a vital application in understanding the physical features of an area before it is inhabited by humans.
Human habitation on steep hillsides can be risky due to potential landslides and soil erosion which may occur due to rainfall or by rivers. It is also important to judge the strength of the underlying geology to ensure stability to the structures and buildings made to support habitation. The faults in the Earth's crust and the movement of the tectonic plates are responsible for causing Earthquakes. Seismic activity can lead to swaying of the structures and result in their instability which happens to risk human lives.

Which events in meiosis are responsible for the principle of segregation? select all that apply
Separation of homologous chromosomes in anaphase 1 is responsible for the principle of segregation.
Mendel put out the law of segregation after noticing that true-breeding pea plants with opposing features produced F1 generations that all displayed the dominant trait and F2 generations that expressed the dominant and recessive traits in a 3:1 ratio. According to the law of segregation, each diploid individual has two alleles (copies) for a specific attribute. During meiosis, the two different alleles for a single gene segregate as the chromosomes divide into several gametes, resulting in each gamete acquiring one of the two alleles.The fundamental tenet of the rule is that copies of genes separate or segregate, resulting in just one allele being passed on to each gamete.Hence in anaphase 1 when the homologous chromosomes are pulled apart the alleles also segregate.learn more about homologous chromosomes here: https://brainly.com/question/8253366

rt A When the diaphragm contracts, _______. When the diaphragm contracts, _______. it lifts the rib cage it flattens out and it rises in the thoracic cavity it flattens out it rises in the thoracic cavity
When the diaphragm contracts, it flattens out.
The diaphragm is a thin layer of skeletal muscle that is seen below the lungs. It is seen at the chest base and it helps to separate the chest from the abdomen. The contraction and relaxation of the diaphragm increase and decrease the thoracic volume which allows the air to enter and exit the lungs.
The contraction of the diaphragm increases the thoracic volume which forces the air to enter the lungs. This process is called inhalation. The diaphragm in its resting state appears dome-like and when it goes back to its resting state it pushed the carbon dioxide-rich air out. This is called exhalation.
The diaphragm is made up of fibrous tissue and skeletal muscles. It has a central tendon that anchors the diaphragm to the ribs. It also has 3 large openings they are esophageal opening, aortic opening, and caval opening. Some smaller ones are also present that allows the nerves and vessels to pass through. The actions of the diaphragm are controlled by the right phrenic nerves and left right phrenic. The inferior phrenic arteries supply blood to the diaphragm.

Transport through Haversian canals
Diffusion through canaliculi

Transport through collagen fibers
Diffusion through canaliculi is the mechanism through which nutrients are brought to spongy bone.
What is the canaliculi in bone?Bone canaliculi are tiny canals that run through the dense matrix of the bone, containing the dendrites of osteocytes, and filled with an ion-rich interstitial fluid. Fluid flow and electrochemical phenomena coexist in very tiny (a few hundred nanometers in diameter) canals. The canaliculi function as a conduit for osteocyte communication, the removal of cellular wastes, and the delivery of nutrients via blood vessels.
Osteocytes maintain contact with one another and with cells on the surface of the bone thanks to gap junction-coupled cell processes that travel through the matrix through tiny passageways called canaliculi. These canaliculi link the lacunae, which contain cell bodies, to other cells and to the outside world.
