Answer: By studying the migratory behavior of the birds.
Explanation:
Evolution is the change in the characteristics of the species with due course of time and from generation to generation. Study of the control mechanism of the bird migration and their evolution also accounts for the evolutionary aspect of the migratory birds and their behavior. It was influenced with the Model of control mechanism.
Answer:
D
Explanation:
When a substance moves from low to high concentration it is moving against its concentration gradient, which requires more energy.
A. It depends on where it is moving, not the substance
OB. This is describing diffusion
OC. Does not require energy, it is passive transport through a semi-permeable membrane
Answer: True
Explanation:
The Borrelia infection or Lyme disease is affected by the bacteria Borrelia burgdorferi. The bacteria is transmitted through the bite of the deer ticks. The infection is associated with symptoms such as fever, fatigue, headache, skin rash called as erythema migrans.
The last stage of the Borrelia infection can be treated with the help of small doses of antimicrobial drugs. The last stage of the disease is associated with arthritis, sever fever, fatigue, headache, sleep disturbance, mental confusion and vertigo. The drugs like doxycycline, amoxicillin, cefuroxime are useful for treatment.
They found that Christian countries, particularly Catholic ones, tended to have more areas set aside for nature than other countries. However, this does not mean White was completely wrong. Other studies suggest that conservative Christians really are less environmentally friendly than other denominations.
Hope this helps :)
Have a great day!
Answer:
Because the have similar limbs.
Because they have similar functions.
Explanation:
(because they have similar limbs)
Homology (evolution) describes a structure that has similar function like limbs on dogs and bears (used for walking) and also have a similar arrangement of bones. The fins on a doplhin might be different from the wings on a bat but they reflect a common origin due to their bone composition e.g carpals and radius bones.
(because they have similar functions)
Analogy (evolution) describes a structure with for example, bird and butterfly wings that have no common ancestor but have the same purpose, in this case flying. They developed independtly as adaptions. This supports natural selection which is a driving force for evolution.
