Adaptive features of Giant land snail
Answer:
Body Adaptations ; The eyes of water-dwelling and land snails have adapted to perch on two eye stalks that can retract and extend from the snails' bodies. These eye stalks slip inside-out when retracting, protecting the snails' eyesight from predators, turf wars and the elements.
Shell Adaptations ; Snails' shells protect them from predators .
Breathing Apparatus ; Freshwater and marine snails have evolved gills, while terrestrial snails sport fully formed lungs.
Secretions ; The slime that snails secrete (the mucus )is an adaptation that helps terrestrial snails survive out of water.
Breathing Apparatus ; Terrestrial snails sport fully formed lungs.

Suppose that you and a friend see brightly colored pigeons like these at a nature park. Because pigeons are usually gray and white, you both wonder where these colors came from. Suddenly, your friend says, "I have a theory. These birds must get their colors from eating food that has the same colors."
Answer:
See the complete question and the answer below
Explanation:
Suppose that you and a friend see brightly colored pigeons like these at a nature park. Because pigeons are usually gray and white, you both wonder where these colors came from. Suddenly, your friend says, "I have a theory. These birds must get their colors from eating food that has the same colors."Is your friend's explanation a scientific theory? Give reasons to explain your answer
The answer is no. My friend's explanation is not a scientific theory.
A scientific theory is a tested and proven phenomenon. In order for a statement to become a theory, it must have been tested through experimentation by several independent researchers and found to be true. A mere statement based on perception with little or no experimental test is just a hypothesis and not a theory.
Instead of my friend to have said, "I have a theory", he should have said, "I have a hypothesis".

Determine the median value for foot width for males and for females.
The data set is missing in the provided question,however the correct data set is provided with answer :
Answer:
Median value :
For males: 9.25
For females: 7.65
Explanation:
Median value is the value that separates higher half to lower half values and is the center point of values of the given set. The method of the finding the median is to arrange the set in order of least to highest value and then if the set of values are even than it is the mid point of the set and in the even set the mean of the middlemost values would be median of the set.
Arranging set in ascending order
For males: 4.5, 7.5, 9, 9, 9.2, 9.3, 10, 10, 10.5, 13.
For females: 5, 7, 7, 7.5, 7.5, 7.8, 7.8, 8, 8, 17
For males mean of the middlemost number is : 9.3+9.2/2 = 9.25
For females mean of the middlemost number is : 7.5+7.8/2 = 7.65

a physicist wants to measure the force required to push a heavy box up a ramp. what tools might the physicist use? what measurements should the physicist take?
Answer:
Flat surface and force applying body.
Explanation:
Flat surface and force applying body are the tools used by the physicist in order to know the amount of force required to push the body. Mass of the body and the acceleration produced from the application of force are the measurements recorded by the physicist. By multiplying value of mass and acceleration we can measure the amount force required to push the heavy box.

Pulses and legumes seeds such as chickpea and mung bean are those seeds which contains starch, fat, protein and leucoplasts. Leucoplasts are present in pulses seeds which is responsible for the storage of starch, lipids, and proteins in the seed. So with the presence of leucoplasts in the seeds, starch, fat and protein stored inside the pulses and legumes.

Which phrase best defines erosion? cementing bits of rock together chemically breaking rocks apart moving bits of rock from place to place physically breaking rocks apart help pls
Answer:
chemically breaking rocks apart
Explanation:
First, lets talk about erosion:
Erosion is the process of eroding or being eroded by wind, water, or other natural agents.
Erosion can be either a fast process, or one that takes hundreds of years.
Water can fall in cracks of rock, later then freeze and expand causing to break rocks more.
Answer: Chemically breaking rocks apart.
Explanation:
Because erosion usually happens because of the flow of water. So the water has sand particles that hit the rock which breaks the rock.
A researcher is studying the number and arrangement of fimbriae covering the surface of a bacterial cell. Which type of microscopy would be most useful for this purpose?
Answer:
The electron microscope
Explanation:
Fimbriae are very tiny appendages of about 3 to 10 nm in diameter found on the surface of most Gram-negative and some Gram-positive bacterial cells. They are mostly utilized as a structure to adhere to one another, to other organisms, or any other surfaces.
Fimbriae generally contain adhesins, a virulence factor that facilitates adhesion to surfaces and due to their tiny size, they can only be viewed using the electron microscope - the scanning electron microscope to be precise.
