What is placebo and why is it used in some experiments
Hoochie [10]
A placebo is kind of a "fake" treatment but, typically the person receiving a placebo is unaware it has no medical effect on them so they believe they are feeling better. For example, a lot of anxiety meds are placebos and people don't know so their brain tricks them into thinking they are feeling less anxious. This could be used in experiments where a group believes they are affected to see how they react

Describe three physical characteristics of monerans?
PtichkaEL [24]
No Nucleus

All members of the kingdom Monera have no nuclei in their cells. All genetic material in moneran cells floats loose in the cytoplasm. In fact, the only parts of the cell that exist in a moneran are the cell wall and the ribosomes. Moneran cell walls are made of peptidoglycan. This is the case for all monerans except for archaebacteria. Monerans also move about using flagella.

Digestion

Monerans digest their food outside of the cell and then absorb the nutrients. Different monerans, however, digest their food in a variety of ways. Some simply generate their own food by making their organic compounds. Others need to feed off of other organic matter, such as decaying material. Some monerans are parasites that feed off of a host and others create a symbiotic relationship with another organism. According to Thinkquest.com, monerans are separated into different classifications by how they feed.

Other Characteristics

Monerans reproduce by both sexual conjugation or asexual binary fission. Circulation is done by diffusion, which is similar to the way they digest. Monerans all breathe differently. Some cannot survive without oxygen while some die if exposed to oxygen. Monerans come in three different shapes: spiral, rod-shaped or spherical. In order to protect themselves, most Monerans are surrounded by a capsule of polysaccharides that keeps them from drying out and acts as protection against other harmful cells.

How did wegner use climate evidence to support his hypothesis​
Novay_Z [31]

Explanation:

Wegener used evidence of climate change to support his hypothesis. As a continent moves toward the equator, its climate becomes warmer. As a continent moves toward the poles, its climate becomes colder. But the continent carries with it the fossils and rocks that formed at its previous locations.
