The index fossil is an example of evidence of unconformity. The statement given in the question if true.
Index fossils are the fossils used to define and identify the different geological periods. The fossils must have a short vertical range with a wide range of geographic distribution and the rapid evolutionary trends.
A fossil indicates the relative age of a rock in which it is found. Index fossils come from species that were widespread but existed for a short period of time.
An unconformity is a buried erosional surface which separates two rock masses or strata of different ages, indicating that the sediment deposition was not continuous. A geologic unconformity is when an older rock formation has been deformed or partially eroded before a younger rock layer, usually a sedimentary rock is laid down which results in mismatched rock layers.
Thus, index fossils can be used as an evidence of unconformity.

Answer:
b. in vessel elements only, after turgor loss point through air-seeding across pit membranes
Explanation:
As in humans, embolism can happen in plants. In the case of plants, embolism occurs only in the elements of the vessel, after the point of loss of the turgor through the propagation of air through the membranes of the pits, in other words, the embolism occurs when there is air filling the empty spaces of the xylem (element of vase), creating air bubbles.
These air bubbles block the xylem's work in transporting water from the root to the other parts of the plants, that is, it reduces the plant's ability to absorb water from the soil, thus preventing the plant from carrying out not only photosynthesis, but numerous metabolic processes essential for your body to survive.
Answer:
A patient is admitted to the emergency room because of uncontrollable flailing arms.After a quick test we determine the cell membranes in their arm nerves are damaged and the cells are not signalling properly. They are endoplasmic proteins.
Explanation:
The endoplasmic reticulum have many functions including the folding of proteins in many sacs called cisternae and the transport of synthesized proteins in vesicle to Golgi apparatus. RER is made up of cisternae, tubules and vesicles.The cisternae are made up of flattened membrane discs which are involved in the modification of proteins.The main function of smooth endoplasmic reticulum is to make cellular products like hormones and lipids.The type of RNA that contains the information for making protein is called messenger RNA or mRNA because it carries the information or message from DNA out of the nucleus into the cytoplasm.Through the process of transcription and translation the information from the genes is used to make proteins.
Well if endoplasmic reticulum stops working there would be many enzymatic processes which would not occur ultimately leading to the death of many cells. Example of protein deficiency is kwashiorkor.Symptoms include fatty liver, flaky skin,diarrhoea, apathy ,failure to grow,edema of belly and legs.This edema is explained by the action of lipoxygenase on arachidonic acid to form leucotrienes and the normal functioning of proteins in fluid balance and lipoprotein transports. Dietary sources of proteins are milk, meats and eggs.Soy and quinoa are vegetable sources of complete proteins.Combining red beans or lentils with wholegrain rice or peanut butter with wholemeal bread also provides complete protein.

b. fluctuations in mood experienced by those suffering a bipolar disorder.
c. fear of snakes experienced by a high percentage of Americans.
d. dramatic increase in reported cases of dissociative identity disorder during the past 40 or so years.
The dramatic increase in reported cases of dissociative identity disorder over the past four decades is least likely to be explained from a biological perspective, compared to biologically-linked issues like schizophrenia or bipolar disorder.
A biological perspective would be least helpful for explaining the dramatic increase in reported cases of dissociative identity disorder during the past 40 or so years. This is because the sudden increase in reported cases is less likely to be due to changes in biological factors—which tend to be more stable over time—and more likely to be due to changes in diagnostic criteria, public awareness, or even social factors. In contrast, the prevalence of schizophrenia, fluctuations in mood experienced by those suffering bipolar disorder, and even common phobias, like the fear of snakes, have more direct connections to biological mechanisms such as genetic risk factors, neurotransmitter imbalances, and evolutionary predispositions.
