Ans.

A placebo can be defined as a substance with no intended therapeutic responses. Examples of common placebos include inert injections (such as saline), inert tablets (such as sugar pills), and sham surgery.

It is used as a blind test, in which subjected people do not know whether they are receiving placebo or real treatment. The main purpose of placebo is to account for the effect of placebo, which is, effects from the treatment which do not depend on treatment itself.  

Thus, the given statement is true.

Option D is correct.

What is meant by herbivory?

Herbivory may be a form of consumption in which an organism principally eats autotrophs such as plants, algae and photosynthesizing bacteria. More generally, organisms that prey on autotrophs in general are known as primary consumers. Herbivory is typically limited to animals that eat plants

What is the herbivory effect?

Herbivory can affect the expansion form of plants by terminating shoot growth and initiating branching and by affecting shoot-to-root ratios. Changes in survival, productivity, and growth of individual plant species affect vegetation structure and community dynasty.

<h3>Why is herbivory important?</h3>

Herbivory can have substantial impacts on habitat health, the structure and variety of plant and soil invertebrate communities and the productivity of economically important crops. The positive impact of herbivory is widely debated within the scientific literature.

If a pink snapdragon is self-fertilized, the offspring are red, pink, or white. What type of inheritance pattern does flower col
BaLLatris [955]

The type of inheritance pattern flower color exhibited in this example is incomplete domination (Intermediate).

<h3>What is meant by incomplete dominance?</h3>

Incomplete dominance or partial dominance is gene expression in offspring based on phenotypic observations that mediate from crosses of parents with different and contrasting characters.

Why intermediate traits can appear in an individual?

An intermediate trait occurs when both heirs are equally strong. The two inheritors of nature are neither closed nor covered. On the other hand, the parents will cover each other because they are just as strong. Offspring with intermediate traits will carry the same combination of traits from both parents.

Mechanical stress applied to bone __________ osteoblast activity in bone tissue, and the removal of mechanical stress __________
iren2701 [21]

Mechanical stress applied to bone increases osteoblast activity in bone tissue, and the removal of mechanical stress decreases osteoblast activity.

Explanation:

Osteoblasts are cells , that are produced in the bone marrow and are responsible for formation of bones and bone matrix.

Whenever a mechanical stress is applied on the bones , a series of reactions are triggered. As a result the activities of osteoblast increases to synthesize more and more bone matrix to provide strength.

Again on the other hand a decrease in mechanical causes a decrease in the activities of the osteoblasts.
