Charles Hillman, an associate professor at the University of Illinois, is conducting research into why children are better at problem-solving after exercise. He places 20 kids, approximately 10 years of age, on a treadmill for 20 minutes. Another group of 10-year-old kids sits in a chair for 20 minutes. Dr. Hillman then measures the brain wave activity of both groups. The group who exercised showed a 5% increase in the P3 waves, which occur during decision- making. What would need to be done in order to make this experimental outcome accepted in the scientific community? Group of answer choices More time would need to be allowed for the experiment. Other scientists would need to confirm the results by performing the same experiment. The same test would have to be done using a different type of exercise. Girls and boys would need to be tested separately and then together.
Answer:
Other scientists would need to confirm the results by performing the same experiment.
Explanation:
According to this question, an experiment was conducted by an associate professor, using 20kids, to discover why children are better at problem-solving after exercise. He arrived at a result that Children who exercised showed a 5% increase in the P3 waves, which occur during decision- making.
However, in order for this findings by Charles Hillman to be generally accepted and recognized in the scientific community, which is a connection of several scientists, the results need to be confirmed by performing the same tests or experiment.
Note that, an experiment becomes a scientific theory if it has undergone series of repeatable tests. One of the key features of scientific experiment is that it must be repeatable.

Describe a non-biological hierarchy that exists in everyday life and how it relates to a biological system.
Answer:
A non-biological hierarchy could be the way the military is organized, with the soldiers at the very bottom and the big commanders on top. (I don't know the specific names for each of them) This relates to a biological heirarchy since the smaller, sadly less important things are at the bottom, like atoms and soldiers, and each group of soldiers makes a regiment (which would be a molecule), then a battalion (which would be a cell), then so on. (I dont know the order of the groups but you can look it up)

Wind pollination required a great deal of excess pollen, just so some of it lands, by chance, in the right place. Animal pollination is more selective because animals pick pollen up and carry it directly to where it needs to be. Although there is still a chance that the pollen will be from the wrong plant species, plants can manipulate variations in animal behavior through the structures of their flowers, the time and season of flowering, or the rewards or attractive chemicals they produce to narrow the field of pollinators, and increase the chances of having exactly the right pollen put in exactly the right place.

Who was the first person to see cells under the microscope and give them name a Robert Hooke b Theodor Schwann c Anton van Leeuwenhoek d Matthias Schleiden
Answer:
a) Robert Hooke
Explanation:
The cell was first discovered by Robert Hooke in 1665, which can be found to be described in his book Micrographia. In this book, he gave 60 'observations' in detail of various objects under a coarse, compound microscope.
The first person to observe the cell under the microscope is Robert Hooke, who is present in Option a. Robert Hooke is the person who first observed cork cells under the microscope and gave them a name. Option a is correct
What is a cell?In the early stages of the earth, cells were not as developed as those of today's eukaryotes; they had RNA as genetic material, and later by evolution, today's eukaryotic cells developed. Those RNA-containing cells were extremely susceptible to mutation, whereas today's DNA-containing cells are not.
The eukaryotic cell contains numerous organelles that perform various functions, such as the lysosome, which degrades pathogens, the chloroplast of plants, which perform photosynthetic reactions, the nucleus of eukaryotic cells, which conserves DNA, and the mitochondria, which generate energy through cellular activities.
Hence, the first person to observe the cell under the microscope is Robert Hooke and gave them a name, who is present in Option a.

This is a timeline depicting the development of atomic ___________. What word should be used to fill in the blank? Support your choice with evidence. A) Law. At each interval on the timeline, scientists described the patterns they saw in both atomic and subatomic structure. Eliminate B) Law. Scientists used observation, experimentation, and mathematical models to explain atomic stricter and the behavior of subatomic particles. C) Hypothesis. Scientists conducted experiments at each interval. They made educated guesses regarding atomic structure and then experimented to support or rejected the hypotheses. D) Theory. At each interval on the timeline, scientists made observations and conducted experiments to explain how atoms and/or subatomic particles behaved in order to determine atomic structure.
Answer:
Subatomic particle, also called elementary particle, any of various self-contained units of matter or energy that are the fundamental constituents of all matter. Subatomic particles include electrons, the negatively charged, almost massless particles that nevertheless account for most of the size of the atom, and they include the heavier building blocks of the small but very dense nucleus of the atom, the positively charged protons and the electrically neutral neutrons. But these basic atomic components are by no means the only known subatomic particles. Protons and neutrons, for instance, are themselves made up of elementary particles called quarks, and the electron is only one member of a class of elementary

Theory. At each interval on the timeline, scientists made observations and conducted experiments to explain how atoms and/or subatomic particles behaved in order to determine atomic structure. Let's take one example: Rutherford's gold foil experiment. Based on observing the behavior of alpha particles directed at a gold foil screen, Rutherford determined that an atom consisted of mostly empty space, with all of its positive charge concentrated in its center in a very tiny volume, surrounded by a cloud of electrons. Yet, further experimentation eventually lead to another model and another theory of atomic structure.

Which of the following could be a sequence in the carbon cycle?
Answer:
plants take in carbon dioxide and produce glucose --> animals consume plants --> animals break down glucose and release carbon dioxide
Explanation:
The carbon cycle is the sequence through which carbon is cycled through ecosystems. The carbon cycle usually occurs in the following order:
First, plants take in carbon dioxide and convert it to glucose.
Then, animals consume plants and break down glucose through the process of respiration.
Finally, this process releases carbon dioxide back into the atmosphere, and the cycle continues.
In activity c, you explored how temperature affects the concentration of dissolved oxygen in a pond use the three data points you collected for the cold Pond to determine the mean dissolved oxygen of the cold pond
Answer:
Add the three data and divided by 3.
Explanation:
Temperature has a great affects on the concentration of dissolved oxygen in a pond because temperature is responsible for the presence of high amount of dissolved oxygen in water. At low temperature such as in winter season, the amount of dissolved oxygen in water is higher while in warm temperature such as in summer season, the concentration of dissolved oxygen is lower. So for measuring the mean dissolved oxygen of the cold pond, you have to add the data and then divided by 3, you will get the average dissolved oxygen of the cold pond.

Small-chain fatty acids can enter the bloodstream directly, but large-chain fatty acids must be packaged first before entering the . can be carbohydrate-, protein-, or fat-based. remove cholesterol from tissues and deliver it to the liver for use in bile or excretion. Linoleic acid and alpha-linolenic acid are considered , and must be obtained from the diet. is needed to help mix fats with watery fluids. Carriers that transport monoglycerides and fatty acids to intestinal cells are called . contains 6 to 8 fatty acids connected to sucrose, and cannot be broken down by digestive enzymes. A is a lipoprotein carrier that transports digested fat and other lipids through the lymph system.
Answer:
lymph
fat substitutes
high-density lipoproteins
essential fatty acids
emulsification (bile)
micelles
olestra
chylomicron
Explanation:
Short-chain fatty acids can be absorbed directly into the bloodstream by the intestine capillaries, while long-chain fatty acids are released into the tiny intestine. Fat substitutes are chemical compounds that have similar properties of fats and oils, with fewer calories than fat. High-density lipoproteins (HDL) are referred as "good" cholesterol because they transport cholesterol from other body parts back to the liver. The alpha-linolenic acid and linoleic acid correspond to omega-3 and omega-6 fatty acids, respectively, and they are essential fatty acids that need to be consumed in the human diet. Emulsification is a chemical process consisting of mixing two immiscible liquids to form a semistable mixture. Micelles are chemical structures formed by the agglomeration of mixed lipids and bile acids, which support the action of lipases for digesting lipids. Olestra is a fat substitute that can be used in low-calorie diets for weight control. Finally, chylomicrons are ultra low-density lipoproteins (ULDLs) composed of triglycerides, phospholipids, cholesterol and proteins. The ULDLs are produced by intestinal cells.
What do paleontologists do when they uncover incomplete fossils
Answer:
Explanation:
Paleontologists are scientists that study the history/existence of past lives by collecting and examining fossils. They use these fossils to determine the history and age an organism has existed. Fossils are remains of dead organisms (plants and animals) which serve as evidence of past lives that have existed on earth in the past. They could include bone remains or footprint of this animals.
Fossils (from bones) are however mostly incomplete because they decompose before they are "stored naturally" by sediments which covers them. When scientists discover this incomplete fossils, they are compared (if there has been similar fossils discovered before then) and are stored and transferred to the lab for examination. This examination includes anatomical comparison (to determine relatedness with other fossils/organisms), carbon dating (to determine age) and data comparison (which includes location and type of soil and habitat).
