do premature infants often need to be placed on a ventilator because their undeveloped lungs produce excess surfactant
False - Babies that are unwell or are still developing receive breathing support from ventilators. Babies who are ill or premature frequently struggle to breathe properly on their own.
To help them breathe "good air" (oxygen) into their lungs and expel "bad" exhaled air, a ventilator may be required. Due to their immature development, premature babies are more likely to have dyspnea after birth, and some of them need help breathing.
The causes of breathing assistance in premature newborns are rarely discussed, though. In order to retrospectively examine the risk factors linked with respiratory aid, the current study enrolled 3,394 premature newborns (665 infants had received breathing support and 2,729 had not).

if we use a cscl gradient to test the density of various nucleic acids, both rna and dna-rna hybrids are more density than just dna. explain why this might be the case.
RNA and DNA-RNA hybrids are more dense than simply DNA if the density of different nucleic acids is tested using a CsCl gradient.
The primary technique employed in molecular biology is the extraction of DNA, RNA, and protein. Scientists can separate materials according to size, shape, and density by using density gradient centrifugation. Isopycnic centrifugation, a sort of density gradient centrifugation that Meselson and Stahl developed, employed a cesium chloride solution to separate DNA molecules solely on the basis of density. Because DNA has hydrogen bonds between its strands, which makes it less dense than RNA, RNA has a far larger density than DNA. RNA can be obtained at the test tube's bottom using a CsCl density gradient and high centrifugation, whereas DNA can be recovered in the middle layer.

in nucleotide excision repair, damaged dna is excised by what enzyme(s)?in nucleotide excision repair, damaged dna is excised by what enzyme(s)?helicasedna polymerasesnucleaseligaseprimase
A method of repairing DNA is called nucleotide excision repair. Chemicals (such as intercalating agents), radiation, and other mutagens continuously cause DNA damage.
Nucleotide excision repair (NER), base excision repair (BER), and DNA mismatch repair are the three excision repair processes that can fix single stranded DNA damage (MMR). The BER pathway can identify particular non-bulky lesions in DNA, but it can only repair damaged bases that have had specific glycosylases remove them. Similar to this, the MMR pathway only targets Watson-Crick base pairs that are mismatched.
The removal of DNA damage brought on by ultraviolet radiation is accomplished by the crucial excision mechanism known as nucleotide excision repair (NER) (UV). Bulky DNA adducts are produced as a result of UV DNA damage; the majority of these adducts are thymine dimers and 6,4-photoproducts. Once the damage is recognized, the brief section of single-stranded DNA that contains the lesion is removed. The single-stranded DNA that is still intact is used as a template by DNA polymerase to create a brief complimentary sequence.

What are the four Importance of meiosis?
Meiosis is in charge of the generation of gametes, which are responsible for sexual reproduction. - It activates genetic information for gamete development.
It cuts the number of chromosomes in gametes cells in half and aids in maintaining a steady number of chromosomes.
Due to the fact that cell division happens twice during meiosis, a single beginning cell can create four gametes (eggs or sperm).
Cells go through four stages throughout each cycle of division: prophase, metaphase, anaphase, and telophase.
Meiosis is critical because it guarantees that all creatures formed through sexual reproduction have the right amount of chromosomes. Meiosis also causes genetic diversity through the recombination process.

In May 2016, scientists discovered a eukaryote organism from a group known as Monocercomonoides that lacks functional mitochondria. Research this organism, and answer these questions:
Does this organism still meet the definition of a eukaryote? Why or why not?
Why can this organism survive without mitochondria?
Without mitochondria, does this organism still carry out all the basic functions of life?
Should the organism be considered a life-form?
Answer:
Yes. A eukaryotic organisms have mitochondria or some degenerate form of mitochondria. Monocercomonoides is an unusual organisms that does not have the slightest indication that it has a mitochondria nor have at least an abbreviated form of mitochondrial proteins. However, scientist conclude that mitochondria must have once been present in this organism and later lost them.
Explanation:
Usually a eukaryote has some genes in their nuclear DNA needed to assemble mitochondria but that genes were not present in Monocercomonoides. It also does not have a gene for making the energy extracting enzymes. Thus, this extraordinary organism refuses to adhere to the basic requirement of a eukaryotes.
However, scientist classify Monocercomonoides to be a eukaryotes though it does not show evidence of having a mitochondria simply because it is now commonly accepted that mitochondrion-related organelles (MROs) are essential composition in all newly discovered eukaryotes and that mitochondrial endosymbiosis takes place before radiation of all extant eukaryotes. It means that evolutionist assume that the mitochondria evolved in the common ancestor of all eukaryotes and conclude that mitochondria must have once been present in this organism and later lost them.
Monocercomonoides can still carry out all of its basic functions of life by obtaining energy from glucose using anaerobic metabolic pathways that operates in the cytoplasm of its cell. They utilize glycolysis, the same non-oxygen-requiring, energy-generating biochemical pathway found in the cytoplasm of all cells to metabolize glucose. It gets more energy by using a series of enzymes that breaks down arginine, an amino acid.
The organism could be considered a life form because evolutionist believed that it started out its existence with mitochondria, received a gene for iron-sulfur cluster synthesis from bacteria and lost its mitochondria. With their strange ways to energize their life and build structures for survival, Monocercomonoides live inside a mammalian intestine, a low oxygen environment.
This protist is a remarkable organism that surprises scientist and pushes the limits of what is actually known in biology.

Red blood cells include the protein hemoglobin, and the term “hematocrit” refers to a measurement of the proportion of red blood cells to all other blood cells in the body.
Anemia is diagnosed using both hematocrit and hemoglobin. Standard blood tests can be used to assess hemoglobin and hematocrit, and both results are routinely provided when a clinician requests a blood count.
The volume percentage of red blood cells in the blood is known as the hematocrit (hct), and it is reported as a percentage. A hematocrit of 25%, for instance, indicates that there are 25 milliliters of red blood cells in every 100 milliliters of blood.
Measure the length of the packed red cells column and divide it by the length of the entire blood column using a hematocrit reader or any other ruling device (cells and plasma). The hematocrit is obtained by multiplying this amount by 100%. Example: The hematocrit is 20/50 = 0.4 or (0.4 x 100%) = 40% if the packed red cell column is 20 mm and the total blood column is 50 mm

Atp is used by organisms as energy. The energy needed to move, grow, digest, and all other processes that require energy.
ATP synthesis takes place in the mitochondria of eukaryotic cells (most ATP synthesis occurs there, but not 100%), ATP is regenerated from ADP through the process of phosphorylation (phosphorylation means "to add a P") and Energy is stored in the covalent bonds between phosphates, with the greatest amount of energy in the bond between the second and third phosphate groups.
An organic substance known as a nucleotide is composed of three different subunits: a nucleobase, a sugar with five carbons, and a phosphate group. Either ribose or deoxyribose may be the sugar. So a nucleoside with a phosphate group is a nucleotide. A nucleotide can be referred to as nucleoside monophosphate (if it only has one phosphate group), nucleoside diphosphate (if it has two phosphate groups), or nucleoside triphosphate (if it has three phosphate groups) (when with three phosphate groups).
A nucleoside can be either a ribonucleoside or a deoxyribonucleoside depending on the pentose sugar it contains. A nucleoside that contains ribose sugar is known as a ribonucleoside.

The flow of highly energetic electrons through the electron transport chain changes the of the pump proteins, which causes them to transport protons across the membrane is true.
The electrons in the electron transport chain (ETC) pass through a chain of proteins that raises its reduction potential and results in an energy release. A proton gradient is produced by pumping hydrogen ions (H+) from the mitochondrial matrix to the intermembrane space with the majority of this energy being lost as heat. This gradient generates an electrical difference with a positive charge outside and a negative charge inside, increasing the acidity in the intermembrane gap. Here, the citric acid cycle oxidizes the NADH provided by glycolysis, converting two electrons from NADH to FMN.
