As a general rule, should sample turbidity corresponds to sample fluorescence in liquid E.coli cultures?
Answer:
Throughout the explanation segment, the description of the query is presented below.
Explanation:
The turbidity spectrometer depending on the intensity isn't a trustworthy indication of microbial cell numbers. However, these should still be utilized as parameter estimates instead of the exact numbers.Benefits at all from the measurement of the radiation reflected by both acutely and chronically organisms, since adsorption capacities change as a result of the current microbiological composition.There is an estimated 10-100 trillion bacteria and other microorganisms living in the human digestive system, forming a mutualistic relationship in which all species benefit. Recently, much research has been done on the role of these microorganisms in the development of disease, the brain, and behavior.

Answer:
- The blood brain barrier is a layer of cells lining the blood vessels within the brain, acting as a filter that controls the molecules that pass between the blood and the brain.
- An organism's gut microbiota is the collection of all the microorganisms (e.g. bacteria, phages, fungi) that live inside the digestive system of that individual.
- A gap junction is a type of intercellular protein connection between animal cells that prevents leakage of materials through the space between the cells.
- The transmembrane protein occludin is one of the component proteins of a tight junction.
- Germ-free mice lack all microorganisms in their digestive systems, a state achieved by delivering them through cesarean section and raising them in sterile incubators.
- Pathogen-free mice are raised under sterile conditions to limit their exposure disease-causing microorganisms.
Explanation:
The blood-brain barrier is a layer of cells made up of endothelial cells that act to limit the passage of substances from the bloodstream in a more selective manner than endothelial cells of capillaries located in other parts of the body. Gut microbiota can be defined as all the microorganisms (i.e., bacteria) inhabiting the mammalian gastrointestinal tract, which helps to ferment non-digestible substrates (e.g., dietary fibers). A gap junction is a class of cell junction that is formed between cells contacting each other which allows small molecules (e.g., water, ions, metabolites, microRNA sequences, etc) to pass through this intercellular communication. In vertebrate animals, cell junctions can be divided into 1-gap junctions (communication between cells), 2-tight junctions (occludin junctions), and 3-adherens junctions, hemidesmosomes and desmosomes (anchor junctions). Tight Junctions are composed of multiple proteins including transmembrane proteins such as occludin, tricellulin, junctional adhesion molecule (JAM), and one member of the claudin protein family. Germfree animals are research animals that have no microorganisms living in or on them, which are housed in controlled/isolated conditions to prevent any type of contamination. Finally, pathogen-free animals are research animals that are guaranteed to be free of particular pathogenic (harmful) microorganisms.

H.L is a 65-year-old Caucasian male diagnosed with Hodgkin’s Lymphoma (NHL) 4 months ago. He just finished receiving his third of six chemotherapy courses 5 days ago. Yesterday morning, he was seen at his oncologist’s office for malaise, muscle weakness, and palpitations. He had splenomegaly on examination. A computerized tomography (CT) scan of the abdomen showed metastatic disease in the liver and spleen. He is admitted to the hospital with progressive disease. The physician confirms a diagnosis of acute tumor lysis syndrome (TLS) and writes a number of orders for H.J.
Required:
What major complication of TLS is H.J. at risk for and why?
Answer:
The correct answer would be - renal failure, kidney stones, uric acid neuropathy and other complications.
Explanation:
The symptoms of H.J include decreased urine output, flank pain, peripheral edema. H.J. is at risk for acute kidney injury which can result in renal failure due to elevated levels of uric acid, BUN, and creatinine.
Uric acid begins to precipitate in the kidneys and leads to conditions such as uric acid nephropathy and subsequent kidney injury. ECG shows in such patients as elevated heart rate due to hyperkalemia and hypocalcemia.
- Muscle cramps, Diarrhea, Nausea, and vomiting
- Renal failure due to kidney stones because of high uric acid.

O B. Prophase
O C. Go phase
O D. Anaphase
it's D. anaphase
hope this helps
The correct sequence of Mitosis are Interphase – Prophase – Metaphase – Anaphase – Telophase. Therefore, Anaphase happens after metaphase. So, the correct option is D.
What is Mitosis?Chromosomes that have been duplicated are split into 2 new nuclei during the cell cycle phase known as mitosis. Mitosis, the process of cell division, creates genetically identical cells with a constant number of chromosomes. Hence, equational division is another name for mitosis.
A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic phase. The cell's contents are often evenly separated into two daughter cells with identical genomes after mitosis.
Interphase, Prophase, Metaphase, Anaphase, and Telophase are the proper phases of mitosis. Anaphase therefore follows metaphase.
Therefore, the correct option is D.

Disinhibition of the lateral geniculate nucleus may be responsible for vivid visual hallucinations in what condition?
a) behavioral variant frontotemporal dementia
b) schizophrenia
c) Alzheimer's disease
d) peduncular hallucinosis
Answer:
d) peduncular hallucinosis
Explanation:
One of the most striking symptoms of perpendicular hallucinosis is the existence of very vivid, colorful, and recurrent visual hallucinations. These hallucinations occur due to lesions of the brainstem and thalamus, which can influence a disinhibition of the lateral geniculate nucleus. The hallucinations provoked can be very debilitating for the person suffering from this illness and can completely disassociate him from reality.

Explanation:
Fibrous joints are the type of joints that is connected by fibrous tissue, consist mainly of collagen. These joints are fixed joints where bones are united by a layer of white fibrous tissue having different thickness. Fibrous joints are present in the neck, in the wrist, knee, hip and at the foot of our body where two bones connect. It does not occur in tooth within the maxilla of human body.
Which structure is the first to collect the urine?
→ Metabolic waste is considered urine first in the collecting duct of the nephron. From the collecting duct, the urine will travel to the minor and major calyces and then the renal pelvis before leaving the kidney via the ureter.
I hope it's helps ╮(＾▽＾)╭
#CarryonlearningThe structure that is the first to collect urine is the calyx. The correct option is B.
What is calyx?The name "calyx" refers to the flower's outermost whorl. The calyx is made up of sepals because they serve as the calyx's functional building blocks.
Urine travels through the renal calyces, which are kidney chambers. The apex of the renal pyramids is surrounded by minor calyces. Each pyramid's renal papillae are surrounded by a little calyx that collects urine from that particular pyramid.
A major calyx is formed when several minor calyces come together. Urine travels from the main calyces into the renal pelvis and then into the ureter. The majority of the sepals' color is green, and they serve to shield the flower's internal organs from damage, mechanical harm, and desiccation.
Therefore, the correct option is B) calyx.

Answer: A
Explanation:
they will have different traits because they will each have different dna but the same amount of genes
Offspring 1 and offspring two will have the same number of genes but different traits. So, the correct option is A.
How the same number of genes?When a sperm fertilizes an egg cell, each parent contributes 23 chromosomes with genetic information to the offspring. This means that each cell of the offspring's body has 23 chromosomes that contain instructions for their development, including their traits.What are the different traits?Parents pass on traits, such as eye color and blood type, to their offspring through their genes. Some health conditions and diseases can be passed on. Sometimes, one characteristic has many different forms. For example, blood type can be A, B, AB, or O.Eye color is based on the amount of pigment melanin in the iris. Every gene has an allele from its parents, so many variations are possible. Because of this, even if parents have blue eyes, offspring can have brown or green eyes, or one offspring can have blue, and others can have different eye colors from their family.Thus, we can conclude that two offspring will have the same genes but different alleles.
