All organisms have adaptations. The list below describes how different adaptations might affect different species.A bird species that develops a longer beak would be able to extract insects from holes that are deep within trees.
A plant species that develops the ability to excrete salt through the leaves of the plant could survive in soils that have high concentrations of salt.
A rodent species that develops the ability to hibernate, or remain inactive during the winter months, would be able to conserve energy when little food is available. Which of the following is true?
Hello. You forgot to enter the answer options. The options are:
"A)Adaptations increase the probability of an organism surviving and reproducing in a specific environment. B)Sudden environmental changes are always necessary for the development of new adaptations. C)The inherited characteristics of a species change over time based on the use or disuse of particular characteristics. D)Adaptations allow individual organisms to change their structures based on environmental conditions."
A)Adaptations increase the probability of an organism surviving and reproducing in a specific environment.
The adaptations of living beings do not occur by chance, much less occurred overnight. Throughout the evolutionary process, some organisms have undergone transformations that have given them greater chances of survival in the environment, adjusting morphologically and physiologically to the ecosystem in which they live.
To these transformations, selected by the environment and caused by mutations, we call adaptation, related to the defense mechanism, reproduction, locomotion, food and unfavorable weather conditions.
Rubber is a insulator so current cannot pass through it where as metal is a conductor which allows current to pass through it
as rubber is an insulator or bad conductor current cannot pass
Explain how if two cases are side by side on a shelf one an have more potential energy
Potential energy = (mass) x (gravity) x (height).
Even if the two objects are at the same height, the one with more mass has more potential energy.
Which of the following is least likely to change the gene pool of a population of chipmunks?
the one that is the least likely to change the gene pool of a chipmunk is: A number of chipmunks die of old age.Dying from an old age is considered a very natural way of mortality. Under normal circumtances, dying from an old age would not disturb overall total population because the reproduction rate usually outnumber the mortal rate
Which landform would be hardest to hike through ? why?
Well, not counting water, i would guess "The Colorado Plateu." ~Because The Colorado Plateu has really straight wall. (meaning its really steep)
I would actually say mountains because it has ribs and crooks, making it hard for people to climb. And especially the rocky mountains.
Which of the following is NOT a likely result of regular physical activity?A. increased energy B. decreased attention span C. improved school attendance D. improved self-image
Please select the best answer from the choices provided.
A B C D
B: Decreased attention span is the answer.
Just took the test on e d g e n u i t y.
Dale and Alex push on opposite sides of a couch. Dale pushes to the left witha force of 100 N, while Alex pushes to the right with a force of 175 N. If the couch has a mass of 55 kg, what is the acceleration of the couch? O A. 5 m/s2 right O B. 5 m/s2 left O c. 1.4 m/s? right O D. 1.4 m/s2 left SUBMIT
C. 1.4 m/s² right
Apply Newton's second law. Take right to be positive and left to be negative:
∑F = ma
175 N − 100 N = (55 kg) a
a = 1.4 m/s²
The couch accelerates to the right at 1.4 m/s².
To find the acceleration of the couch, use Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration. The net force is calculated by subtracting the forces applied by the two individuals pushing in opposite directions. By plugging in the given values and solving the equation, the acceleration of the couch is found to be approximately 1.4 m/s² to the right.
To find the acceleration of the couch, we need to use Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration. In this case, the net force is the difference between the forces applied by Dale and Alex, since they are pushing in opposite directions.
The net force can be calculated as 175 N (force applied by Alex) minus 100 N (force applied by Dale), which equals 75 N. The mass of the couch is given as 55 kg. Plugging these values into the equation, we get:
Net force = mass × acceleration
75 N = 55 kg × acceleration
Dividing both sides of the equation by 55 kg gives us:
acceleration = 75 N ÷ 55 kg ≈ 1.4 m/s²
Since the net force is positive (to the right) and greater than zero, the acceleration of the couch is also to the right. Therefore, the correct answer is 1.4 m/s² right (option C).
