Gram-negative cell wall contains an outer membrane called the lipopolysaccharide (LPS). This LPS is found in the outer leaflet of the outer membrane. The innermost portion of the LPS is called Lipid A, which is an endotoxin. When are endotoxins released from a bacterial cell?
Answer:
The correct answer is - during active cellular growth and after cell lysis
Explanation:
Endotoxins, also known as LPS, are part of the outer leaflet of the outer membrane of the cell wall of gram-negative bacteria. These LPS especially Lipid A LPA released into the circulation when there is a disruption of the intact bacteria or after cell lysis. These are present in cell-associated bacteria such as Gram-negative pathogens such as Escherichia coli, Salmonella, Shigella, Pseudomonas, and others.

All of the following factors contribute to the differences in complex trait risk predictions between different laboratories, EXCEPT ____________. differing methods of combining risk from multiple genetic variants selection of different genetic variants for risk determination different assessments of environmental factors genotyping of different variants
Answer:
different assessments of environmental factors
Explanation:
In humans, for predicting the future phenotype of any individual, the PSR is used.
A trait may be defined as the state of a character that is a distinct variation of the phenotypic characteristic of any organism.
The following factors contributes to the differences in the complex trait risk predictions in the different laboratories :
-- differing methods of the combining risk from the multiple genetic variants.
-- genotyping of the different variants.
-- selection of the different genetic variants for such risk determination.
Thus the factor which does not contribute is :
"different assessments of the environmental factors."

Hemophilia is an X-linked recessive condition in which blood does not clot properly. Queen Victoria of England had one allele for hemophilia. Most of her male descendants had the disorder, but few females had it. Why did hemophilia occur more frequently in Queen Victoria’s male descendants?
Answer:
Because hemophilia is an X-linked recessive condition.
Explanation:
As the problem states, hemophilia is an X-linked recessive condition.
Meaning that in Queen Victoria's female descendants (coded XX) which inherited the Queen's one allele, for hemophilia to appear in them it would be necessary to inherit another hemophillia-carrying allele from the father.The Queen's male descendants (coded XY) would always manifest hemophilia if they inherited the Queen's hemophilia allele, as they possesed only one X gene.Define external digestion
Answer:
Saprobionts eat by secreting enzymes through the cell membrane onto their food, a process known as extracellular phototropic digestion. The enzymes catalyze the breakdown of food into molecules small enough to be absorbed by passive diffusion, transport, osmotrophy, or phagocytosis.

What happens to proteins with no signal sequence that are made in the cytosol? Question 3 options: They are taken up by lysosomes. They are degraded by proteases. They are returned to their organelle of origin. They are secreted. They remain in the cytosol.
Answer:
The correct answer is: They remain in the cytosol.
Explanation:
Eukaryotic proteins are made through a process called Translation, which always starts at the cytosol (except for the proteins that are made in the mitochondria).
While Translation is taking place, the peptide that is being synthesized is checked for molecular tags that will lead to a re-routing to another destination: proteins that have an amino sequence called 'signal peptide' will be sent to the endoplasmic reticulum for its translation to continue - the proteins that go this route are meant to be part of the endomembrane system, after that they can be bounded to the ER, the Golgi apparatus or the lysosomes.
Unlike the proteins mentioned before, there are proteins that will have no signal peptide - this means that they are meant to finish Translation in the cytosol. Some of these proteins will acquire a signal tag that will lead them to the nucleus or the mitochondria, for example, but if they don't they will stay permanently in the cytosol to perform their tasks in that place.
You are out hiking and walk past a great outcrop of granite that is part of an exposed batholith. Looking closer you notice pieces of sandstone within the batholith. Which rock is OLDER, the granite or the sandstone?
Answer:
Sandstone is younger than the granite rocks
Explanation:
As the rocks layer found at the bottom are the oldest and closer to the ground surface are the younger. This is due to the law of superimposition and as when looking at the outcrops you will notice pieces of sandstone within the batholith that indicates that the base is formed by granite and is later cemented by sandstone rockIN____________ NUTRITION , THE ORGANISMS DEPEND UPON ITS HOST FOR ITS FOOD .

define cell and atom.....
Cell: A cell is the structural and fundamental unit of life. The study of cells from its basic structure to the functions of every cell organelle is called Cell Biology.
Atom: atom is the smallest component of an element, characterized by a sharing of the chemical properties of the element and a nucleus with neutrons, protons and electrons. The protons and the neutrons reside in the nucleus.
whats the difference between atom and cell?
function wise atoms take part in every chemical reaction while cells are responsible for the development and growth of living existences. Atoms do not have life. They do not need food, water, and they do not reproduce. Cells are alive. Cells consume food and water and can reproduce. Atoms construct molecules and Cells make tissues for organs.

what must be true about two objects if heat is flowing between them
Answer:
The objects must be the same temperature.
Explanation:
if heat is flowing between two objects, so both the objects must have the same temperature because the heat in object 1 passes to the object 2 due to the conduction property present in these objects. The heat flows from one body to another body until both have the same amount of heat energy as well as temperature so that's why we can say that both objects must be the same temperature.

Dark skin ( a result of increased melanin production in equatorial populations), is likely a response to ultraviolet radiation because UV radiation causes:
Answer: Skin cancer
Explanation:
Melanin is a pigment derived from an amino called acid tyrosine. The most common form of melanin is called eumelanin, which is a polymer of dihydroxyindole carboxylic acids and their reduced forms. When a person is exposed to the ultraviolet light (UV) from the sun, the melanocytes will produce eumelanin to prevent the skin from burning and damage to the cell nuclei (where DNA is found) of the epidermis. This melanin production causes the skin to darken. The eumelanin in the skin then acts as a natural sunscreen by blocking the damaging effects of sunlight. So, skin darkens when exposed UV light, thus providing greater protection when needed by producing more eumelanin, but it also becomes more likely to develop melanoma, which is a type of skin cancer. This is because UV rays damage the DNA of skin cells. The DNA (deoxyribonucleic acid) is the genetic material that has the instructios to the growth and functioning of an organisms). Skin cancers begin when eumelanin protection is not sufficient and this damage affects the DNA of the genes that control the growth of skin cells. This results in a tumor, which is the uncontrolled growth of cells (in this case, skin cells) because there will be a mutation in DNA that affects the function of the cells.
how digestion happens in human
Explanation:
The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream.
Answer :Once foods are broken into small enough parts, your body can absorb and move the nutrients to where they are needed. Your large intestine absorbs water, and the waste products of digestion become stool. Nerves and hormones help control the digestive process.

The ability of the human body to break down the red color in beets is controlled by an autosomal dominant allele. The inability is recessive, detected by red coloration of the urine (we will call this phenotype 'secretor'). If a nonsecretor woman with a secretor father has children with a nonsecretor man who in a previous relationship had a secretor daughter, what is the probability that their first child will be...
Solution :
It is given that a woman is a nonsecretor but the father of that woman is a secretor. It means that the father's genotype is recessive, i.e. "ss".
The genotype of the nonsecretor mother would be Ss, who have received one recessive allele from her father.
Now the nonsecretor man have a secretor daughter from his previous marriage. That means that he is a carrier nd his genotype is Ss.
Now, we can cross between the heterozygous parents (Ss x Ss) will have offspring with the following genotypes :
1 SS -- Nonsecretor
2 Ss -- Nonsecretor
1 ss -- secretor
Thus the probability that their first child will be :
a). a secretor girl
[tex]$=\frac{1}{4} \times \frac{1}{2}$[/tex]
[tex]$=\frac{1}{8}$[/tex]
b). Non secretor girl
[tex]$=\frac{3}{4} \times \frac{1}{2}$[/tex]
[tex]$=\frac{3}{8}$[/tex]
c). a secretor boy
[tex]$=\frac{1}{4} \times \frac{1}{2}$[/tex]
[tex]$=\frac{1}{8}$[/tex]
Upon completion of seeding a flower and a vegetable, research and identify the optimum propagation conditions, such as, water and light demand, appropriate temperature, and, other elements that may affect the germination from seeding. Compare your research findings with your existing conditions. If any discrepancies found, address how you would like to mitigate. Describe the entire process in your weekly lab report journal. Add photos, sketches or other supplementary information, if necessary.
Answer:
Needs optimum environmental conditions.
Explanation:
Seedling, a flower and a vegetable needs suitable conditions for growth and development. All of the three stages of plant life cycle requires optimum water, fertilizers and light intensity in order to grow and develop at full speed. Seeds need a specific temperature in order to germinate. Most seeds germinate when the soil temperature is between 68 and 86 Fahrenheit. In the same way the plant also needs specific temperature for bearing flowers. All the stages requires optimum water in the soil for absorption.
