Attentional Blink is a phenomenon characterized by the individual failing to detect a second visual stimulus that is presented _____ milliseconds after the first stimulus
Answers
Answer:
200 to 500 milliseconds
Explanation:
Attentional blink is a phenomenon that puts time-related limitations to the ability to utilize visual attention. When an individual must identify two visual stimuli presented one after another, the accuracy is very poor for the second stimulus if it occurs within 200 to 500 milliseconds of the first stimulus.
So, in our question, the gap is filled by 200 to 500 milliseconds.

Ribulose biphosphate carboxylase is a chemical that aides in the process of photosynthesis. Ribulose biphosphate carboxylase breaks down carbon dioxide and bonds carbon atoms together to begin the formation of sugars. Without ribulose biphosphate carboxylase, photosynthetic organisms would not be able to produce as much food. Even though ribulose biphosphate carboxylase is involved in assisting chemical reactions, its chemical structure is unchanged.
Based on the information about the function of ribulose biphosphate carboxylase, what is the best classification of the chemical?
A.Carbohydrate B.Enzyme C.Lipid D.Nucleic Acid
Answers
Answer:
The correct answer is - B. Enzyme.
Explanation:
RubisCo or ribulose bisphosphate carboxylase is an enzyme and most abundant protein on the earth that catalyzes the formation of the sugars from the CO2 by the photosynthesis process.
As it is given that in absence of the RuBisCo enzyme the cells plants or the photosynthetic organisms are not able to produce as much food as they produce in presence which means it has an essential role in increase the photosynthetic process to produce the food. By this, we can say it is an enzyme that helps in the process of photosynthesis.
1. Which of the following correctly pairs a structure in a eukaryotic cell with its description?

D. cytoskeleton; consists of all genetic information needed by the cell
Answers
Answer:
B. plants cells have chloroplasts
Explanation:
..
DNA found in cytoplasm is correctly pairs a structure in a eukaryotic cell with its description. Thus, option B is correct.
What are Eukaryotes?Eukaryotes (or Eukaryota) are a domain grouping all unicellular or multicellular organisms that are characterized by the presence of a nucleus and usually mitochondria in their cells.
He opposes the domains of Eubacteria and Archaea.Eukaryotes gather four great kingdoms of the living world: animals, mushrooms, plants and protists (or protozoa).
Eukaryotes are organisms whose cells have a nucleus enclosed within membranes. All protists, fungi, plants and animals such as yeasts, fungi, Protozoa and Plant cells are examples of eukaryotes. While prokaryote is a unicellular organism that lacks a membrane-bound nucleus, or any other membrane-bound organelle. Bacteria and blue-green algae are examples of prokaryotic cells.
Therefore, DNA found in cytoplasm is correctly pairs a structure in a eukaryotic cell with its description. Thus, option B is correct.

In infective endocarditis, septic emboli may break off. What is/are the possible outcome(s) of emboli in the circulation?
Answers
Answer: The possible outcomes of septic emboli in the system is it's ability to cause metastatic infections in various organs of the body.
Explanation:
Infective endocarditis is defined as the infection of the lining of the interior surfaces of the heart chambers ( the endocardium). This infection is usually caused by microorganisms such as bacteria and fungi. One of the major types of complications of infective endocarditis is septic embolism.
Septic embolism is the fungal or bacterial infection of a mass ( blood clot, air bubbles or foreign materials) which breaks off from their original location that has been infected for a long period of time ( example is the infective endocarditis).
The possible outcomes of septic emboli in the system is it's ability to cause metastatic infections in various organs of the body. The organs and organ systems that are mostly affected includes:
--> Central Nervous System,
--> Bone and joint structures
--> Liver,
--> Kidney,
--> Sleen,
--> Lungs and
--> Coronary Vessels.
Depending on the location of the detached emboli in the body complications caused by this effect includes: acute diffuse glomerulonephritis, bacterial meningitis,splenic abscess, pleuritic chest pain,hepatic abscess just to mention a few. I hope this helps, thanks.

1. Why is it important that the same mass of each food is analyzed?
Answers
Answer:
Explanation:
In any form of experimental research where data is being analyzed, there needs to be only one variable present and each group in the experiment needs to have the same factors and environment as the others. That way the single variable can be isolated and the data properly analyzed. That is why it is important for the mass of each food to be the same, since the foods are already different variables the rest of the factors in the experiment need to be the same including the mass of each food.

Imprinting disorders do not involve changes in DNA sequence, but only the methylated state of the DNA. Does it seem likely that imprinting disorders could be treated by controlling the maternal environment in some way, perhaps by dietary changes?
Answers
Answer:
It is confirmed that epigenetic changes play a significant role in imprinting disorders and food like folic acid, vitamin B12 and other certain food can affect the DNA methylation process.
Demethylation of DNA has been effective to human disorders even though methylation is an important and natural process, may be useful for regulating one gene which can lead to various changes that need to be avoided.

Answers
Answer:
The average speed is 60 miles per hour or 1 mile per minute.
Explanation:
If you multiply 30 by 2 to find the miles per hour, you also have to multiply 30 miles by 2. This results in 60 miles per hour. If you want to find the miles per minute, you divide the 30 minutes by 30. You have to do the same to the miles, so the average speed could also be 1 mile per minute.

Look at the map below. The mountains in the Pinnacles National Monument and the mountains at Tejon Pass were once located next to each other and
a part of the same mountain range Now however, they are separated by over 240 kilometers Explain how the mountains at Pinnacles National Monument
and the mountains at Tejon Pass became separated from each other koi
Answers
Answer:
The mountains at Pinnacles National Monument and the mountains at Tejon Pass became separated from each other after suffering a transforming process, in which plates slid laterally against each other along the fault.
Explanation:
The tectonic plates theory is based on the continual movements of the crust and might explain the movement of the different plates, and their directions and interactions.
Plates are limited by three different ridges or borders that differ in the type of movement they produce.
Divergent limits: two plates get separated.Convergent limits: These movements occur when two plates collide.Transforming limits refer to geological structures related to the seafloor expansion and associated in general with the oceanic ridge, although they might also occur in the continental plate. These limits are known as geological faults, where no rocky material is either destroyed or formed. When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur. The movement breaks the crust and originates pronounced fractures. The San Andrés fault is an example of these plate ridges.A subduction process first originated all the mountains. This process took a lot of time and it in different stages. But once it concluded, a new process followed the first one. The transforming process, which occurred when the Pacific plate collided against the occidental ridge of the North American plate until it broke along the tension line. This process involves a movement of plates in which they slide laterally against the others along a line known as a fault.
As you can see on the map, the Pinnacles National Monument and the mountains at Tejon Pass are placed on opposite sides of the fault line. At first, they were together, and then by the transforming process, the plates moved along the fault separating them.
