<span>"Those who doubt the effectiveness of this treatment for pain attribute the pain relief to a placebo effect: if a patient believes something will reduce their pain, they will experience some relief."
The method of acupuncture only provides the placebo effect, so it just gives a psychological benefit to the patient receiving acupuncture.
Hope this helps. :)</span>
Answer: B- Thicker leaves
Explanation:
Plants in drier areas develop thick leaves in which they can store water. The water stored there is usually protected by a thick waxy layer so that water loss through transpiration thus enabling the plant to have enough water to keep surviving until more can come.
Examples of plants with thick leaves include: Aloe Vera and Haworthia.
Answer:
The cell (from Latin cella, meaning "small room"[1]) is the basic structural, functional, and biological unit of all known organisms. Cells are the smallest units of life, and hence are often referred to as the "building blocks of life". The study of cells is called cell biology, cellular biology, or cytology.Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids.[2] Most plant and animal cells are only visible under a light microscope, with dimensions between 1 and 100 micrometres.[3] Electron microscopy gives a much higher resolution showing greatly detailed cell structure. Organisms can be classified as unicellular (consisting of a single cell such as bacteria) or multicellular (including plants and animals).[4] Most unicellular organisms are classed as microorganisms.
The number of cells in plants and animals varies from species to species; it has been estimated that humans contain somewhere around 40 trillion (4×1013) cells.[a][5] The human brain accounts for around 80 billion of these cells.[6]
Cells were discovered by Robert Hooke in 1665, who named them for their resemblance to cells inhabited by Christian monks in a monastery.[7][8] Cell theory, first developed in 1839 by Matthias Jakob Schleiden and Theodor Schwann, states that all organisms are composed of one or more cells, that cells are the fundamental unit of structure and function in all living organisms, and that all cells come from pre-existing cells.[9] Cells emerged on Earth at least 3.5 billion years ago.[10][11][12]
Answer:
The correct answer will be option-A.
Explanation:
The appendicular skeleton is the skeleton system of vertebrates which includes the bones of upper limbs, lower limbs and the shoulder girdles and pelvic girdles which attaches the upper limb and the lower limb.
The upper limb consists of the bones which help in grasping and manipulating the objects like the bones of arm, forearm, wrist and hand. The lower limb consists of the bones of thighs, legs and the feet which helps in the movement of the body.
Thus, option-A is the correct answer.
Answer:
The basic processes of life include organization, metabolism, responsiveness, movements, and reproduction. In humans, who represent the most complex form of life, there are additional requirements such as growth, differentiation, respiration, digestion, and excretion.
