This movement aids the cell membrane in preserving its function as a partition separating the interior and exterior cell surroundings. Thus option B is correct.
What is the role of transport protein in fluid mosaic model?Integral proteins protrude from each end of the phospholipid bilayer and are tucked inside. Larger molecules like glucose can be transported through cell membranes with the aid of integral proteins.
They have sections that match the polarity of the phospholipid bilayer, known as "polar" and "nonpolar" regions.
This movement aids the cell membrane in preserving its function as a partition separating the inside from the outside environments of the cell.
Therefore, in the fluid mosaic model, the transport protein is connected to the phospholipid bilayer's outer layer.

Which pair of factors affects the force of gravity between objects? direction and distance mass and distance mass and shape shape and time
Answer:
It's B
Explanation:
Mass and distance affects the force of gravity between objects.
Thus, option B is correct.
What is force of gravity?Force of gravity is defined as the force of attraction between any two objects in the universe.
The force of attraction depends upon the mass of the object and the square of the distance between them.
Mass is the total amount of matter contained by an object.More the matter of the object has, the more the mass.Weight of an object can be zero but mass of the object cannot be zero.
Distance is defined as the amount of space between two places or things. Measurement of distance are kilometer, inch, foot, yard.
Therefore,Mass and distance affects the force of gravity between objects.

Compare and contrast the genome organisation, infection strategies and diseases of a multipartite and monopartite virus.
Answer:
Multipartite viruses have one of the most puzzling genetic organizations found in living organisms. These viruses have several genome segments, each containing only a part of the genetic information, and each individually encapsidated into a separate virus particle. While countless studies on molecular and cellular mechanisms of the infection cycle of multipartite viruses are available, just as for other virus types, very seldom is their lifestyle questioned at the viral system level. Moreover, the rare available “system” studies are purely theoretical, and their predictions on the putative
benefit/cost balance of this peculiar genetic organization have not received experimental support. In light of ongoing progresses in general virology, we here challenge the current hypotheses explaining the evolutionary success of multipartite viruses and emphasize their shortcomings. We also discuss alternative ideas and research avenues to be explored in the future in order to solve the long-standing mystery of how viral systems composed of interdependent but physically separated information units can actually be functional.
The perusal of the literature presented above illustrates our current ignorance on the reasons explaining why multipartite viruses are so successful. The simple fact that they can be ssRNA, dsRNA, or ssDNA likely indicates that multi-encapsidation has evolved more than once, and yet we are unable to confirm any associated beneficial aspects. The proposed putative benefits are not yet convincing because of a lack of data, and because most also appear valid for segmented virus, thus not explaining multi-encapsidation. We believe further experimental work on the specifics of the biology of multipartite viruses is necessary to evaluate and challenge the existing hypotheses, and, even better, propose new ones perhaps more pertinent or unforeseen. A possibility that should not be ignored is that, because multipartitism most likely evolved independently several times, its evolution may have responded to distinct selection pressures: it is possible that the reasons that led to the evolution of multipartitism differ in different groups of viruses and that potential benefits that exist in one group do not exist in another. As concluding remarks, we outline a few research lines that could clarify or assign specific properties to multipartite viruses that we judge immediately critical.
Structural, physical, and biochemical properties of the virus particles depending on the contained segment(s) should be investigated in more detail. An important outreach of these studies (detailed in section 4) is that distinct properties of particles containing different segments may reflect an adaptive process involved in the temporal regulation of gene expression specific to multipartite viral systems. Although such variable particle properties were shown to be related to the RNA folding structure, they may also be important for multipartite ssDNA viruses in which secondary/tertiary folding structures of various segments appear to have unknown biological functions [97].
Also related to the regulation of gene expression, the discovery of the genome formula in populations of the nanovirus FBNSV [50] contributes to the consideration of a putative important role of gene copy number variations in the biology of viruses. Prominent questions are whether the genome formula is also controlled in other multipartite viruses, whether it actually regulates gene and phenotype expression, and whether it is an adaptive and evolvable trait. While arguments in favor of the adaptive regulation of gene copy number in multipartite viruses are discussed in section 3, a direct experimental demonstration is still lacking.

Why have plants in the alpine biome adapted to survive on limited nutrients?
Answer:
The soil in the alpine biome is rocky and nutrient poor. Plants that live in the alpine biome must be suited to the nutrient poor soil.
Explanation:
The plants living in the alpine biome are adapted to survive on limited nutrients as the conditions in the alpine biome is harsh and not favorable. Hence, the plants have to adapt the mountain climate.
What are adaptations?An adaptation is any physical or behavioral feature of an organism that helps them to survive better in their environment. In other words, an adaptation is something that helps them in finding food, water, mates, and shelter.
The alpine climate is the typical climate for elevations above the tree line, where the trees fail to grow due to cold conditions. The climate of alpine biomes is also referred to as the mountain climate or highland climate.

A person filters 720 millimoles of K in a day and secretes 42 millimoles. She excretes 75 millimoles in her urine. How much is K is reabsorbed, in millimoles
Answer:
687millimoles
Explanation:
To calculate the amount of K reabsorbed in the kidney of an individual, we say:
Amount reabsorbed = Amount filtered + Amount secreted - Amount excreted
Based on the provided information,the respective amount of K is:
Amount filtered = 720 millimoles
Amount secreted = 42 millimoles
Amount excreted = 75 millimoles
Hence,
Amount reabsorbed = 720 + 42 - 75
Amount reabsorbed = 762 - 75
Amount of K reabsorbed = 687millimoles

If, somehow, the number of daylight hours did not change throughout the year, but Earth was still tilted at 23.5° then-
Yes, there would still be seasonsNo, the temperature difference between the seasons would not be as greatThe tilt of the Earth's axis at 23.5° leads to the different parts of the Earth to gets a high or less amount of direct sunlight at different times of the year.
If there would be no tilt of the earth then there would be no seasons on Earth.If the number of daylight hours did not change then seasons still be there due to the intensity of light would still change throughout the year as the earth is still tilted. If the number of daylight hours did not change throughout the year then the temperature difference would not be as great due to less light in the daytime will not be able to heat enough and the Earth would not be heated for a longer time in summer.Thus, the correct answer is -

You have been studying the lysosomal enzyme cathepsin D in mammalian cells. To look at the localization of the enzyme, you incorporate 32 P into the cells over a long period of time and collect fractions of the cell lysate corresponding to various organelles. Much to your surprise, you find cathepsin D was isolated in the ER fraction, and it contains 32 positive sugar side chains. However, when you pass this enzyme through an affinity chromatography column containing mannose-6-phosphate receptor conjugated to resin, the enzyme passes straight through. However, your cousin calls you up and tell you that she modified your cell line. She claims that she deleted your endogenous cathepsin D gene and transfected a plasmid containing a cathepsin D gene with a Lys-Asp-Glu-Leu (KDEL) sequence on the C-terminus.a) Why is the lysosomal enzyme found in the ER fraction rather than in the lysosomal fraction?b) Explain why the modified enzyme does not bind to the mannose-6-phosphate receptor.
Answer:
Explanation:
1.
Cathepsin is involved in programmed cell death, it is a lysosomal enzyme and the reason it is found in the ER fraction instead of the lysosomal fraction is because of its c terminal KDEL sequence. this sequence ia a retrieval for protein and causes a backward movement of protein back to endoplasmic reticulum. that is why cathepsin seems to have localised in ER instead of the lysosomal fraction
2 It does not bind to mannose-6-phosohate receptor because this glycosylation process does not occur in the E.R but in Golgi bodies. because of the KDEL sequence this glycosylation of cathepsin would not occur and cathepsin would go through affinity column without any form of binding to receptor.If cathepsin can get to the Golgi then glycolysation with Mannose6phospate can occur.
