IV:
DV:
Hypothesis:
I wonder if the amount of studying I complete has an effect on my science test scores?
IV:
DV:
Hypothesis:
Answer:
1) IV: The quantity of salt added
DV: The resultant density of the salinated water
Hypothesis: The egg will float when the mass of the volume of the salinated solution displaced by the egg is equal to or larger than the mass of the egg
2) IV: The extension of the rubber band above original length in centimetres
DV: The distance flown by the rubber band
Hypothesis: The potential energy stored in the rubber band by pulling will be transformed into kinetic energy and the larger the extension, the larger the stored potential energy, and the larger the resultant kinetic energy, the higher the velocity and the further the distance flown
3) IV: The wing span of a paper airplane
DV: The distance flown by the plane
Hypothesis; The glide of the airplane is a factor of the wings span increased wingspan increased glide and increased travel distance
4) IV: Presence of more light
DV: Height to which plant grows
Hypothesis: Photosynthesis, which is the conversion of carbon dioxide and water into glucose and oxygen in the presence of Sunlight is essential for plant growth and the more the presence on light is increases the higher plant will tend to grow
5) IV: Amount of vinegar in the canister
DV: The height a rocket will launch
Hypothesis: With a given amount of baking soda, in the canister a little amount of vinegar causes a delayed launch but an increased build up of carbon dioxide resulting in higher height reached than when more vinegar is used in which case the lift off will be more rapid but the power will be lesser and the height reached reduced
6: IV: Surface area of the coin
DV: The number of drops held
Hypothesis: Due to surface tension and cohesion which are properties that increase with surface area and as such a coin with a larger surface area holds more water drops
7. IV: Number of hours of study
DV: Science score
Hypothesis: A student science scores is directly related to the amount of science topics thought the student is able to respond to in a test and it is directly proportional to the amount of study the student has done related to the science topics

Object is not moving Answer 1 Choose... Object is moving towards observer Answer 2 Choose... Object is moving away from observer Answer 3 Choose...
Answer:
Object is moving away from observer.
Explanation:
If a force is applied to an object it starts moving. The object will move towards the observer, this is known as Doppler effect. It is when an observer or the thing under observation moves. There is change in its position due to a force exerted on it. The motion of the object also depends on the direction of force.

The University of California Cooperative Extension and the county of Humboldt did a study, and estimated that in order to produce all the beef eaten in the county each year, 365,000 acres of land were needed.
Answer:
For the production of food for animals.
Explanation:
365,000 acres of land were needed for the production of feed for animals in order to produce beef. Feed such as grasses, berseem, shaftal and maize etc are given to animals because these plants has high protein content which is necessary for the production of meat in animals. If proper feed is not provided to animals so they becomes weak and low in meat which will not fulfill the beef need of a country so proper feed is necessary for the production of high amount of beef.

In the autumn, many birds will collect seeds and then hide them in various caches throughout their habitat. The birds will guard their caches from other birds, and move the caches if they start to dry out. These caches provide a food source for the birds during the winter. What is an abiotic factor that contributed to the evolution of this set of behaviors? A. being preyed upon by larger birds B. competition with other birds for space C. limited food availability D. cold winter climate
Answer:cold winter climate
Explanation:During winter specially in the eastern and western part of the world....snows bury grounds and food that enables this organisms live....and cold can also affect them
Answer:
Answer: c. limited food availability
Explanation:
Both biotic and abiotic factors are responsible for shaping the evolutionary framework of the population. Resource availability can be one of the important abiotic factor in determining the evolutionary dynamics of the population or species. Limitations in resource can result in increase in competition. According to population exclusion principle when two species compete for the same limiting resource this results in co-evolution of both the species. But the extent of evolution may vary among the species. The one which undergoes more favorable evolution will be stronger competitor and drive more resources and will be fit for survival in adverse limiting conditions.

Can podocyte cells in the Bowmann capsule attach to any other basement membrane other than the glomerular basement membrane? That is, it can itself have a separate layer of base membrane?
Answer:
"Podocytes are cells in the Bowman's capsule in the kidneys that wrap around capillaries of the glomerulus. Podocyte cells make up the epithelial lining of Bowman's capsule, the third layer through which filtration of blood takes place.[1] The Bowman's capsule filters the blood, retaining large molecules such as proteins while smaller molecules such as water, salts, and sugars are filtered as the first step in the formation of urine. Although various viscera have epithelial layers, the name visceral epithelial cells usually refers specifically to podocytes, which are specialized epithelial cells that reside in the visceral layer of the capsule.
