Explain the difference between control group and experimental group

Biology
1 answer:
Elan Coil [88]4 years ago
7 0
A control group is kept the same to determine whether or not what you did for an experiment on the experimental group was actually caused by the experiment performed, and not other environmental changes. By keeping the same climate, environments, nourishment, etc. on a control group and experimental group, but only performing the experiment on the experimental group, you can prove your experiment actually works.

Nana76 [90]

Answer:

Part of the extracellular matrix secreted by osteocytes. (Ans. B)

Explanation:

Cells which are present on bones are known as osteocytes. Bone is composed of extracellular matrix, and cells. There are three types of cells which are present in the bones:

1) Osteoprogenitor cells.

2) Osteoblast.

3) Osteocyte.

Extracellular matrix is composed of organic matrix consisting glycoproteins, proteoglycans, osteocalcin also known as calcium binding proteins, and osteonectin which anchors bone mineral to collagen.

Are gender traits completely a result of societal expectations? Justify your answer.​
ExtremeBDS [4]

Answer:

No. Gender traits in humans are largely determined by biophysical processes.

Explanation:

There seems to be a vocal political faction that is trying to convince people in the name of liberty and equality that gender traits are completely learned, and therefore arbitrary. But this claim disagrees with scientific evidence. In general, boys play more with cars and girls play more with dolls not because their parents are perpetuating outdated gender stereotypes, but because their brain is telling them to. This fact does not mean that boys have to play with boy toys, or that boys who play with dolls aren't really boys. It is just a scientific observation about average behavior and its link to fetal development.

Answer The Following Questions:
Vanyuwa [196]
  1. Yes. Upper-layer skin cells and the cells in the front surface of the eyes get a significant amount of oxygen directly from the air rather than from the blood. Human bodies have a huge demand for oxygen. As a result, the oxygen that is able to passively diffuse into the body directly from the air is not nearly enough to run the whole body. Fortunately, we have lungs that can actively pull in oxygen and transfer it to the blood, allowing the body to transport oxygen to the cells by using the blood like a fleet of delivery trucks. Most of our cells rely on the blood delivery service. However, the cells in the outer layers or our skin and eyes are in direct contact with the atmosphere and can efficiently get their oxygen right from the air.
  2. Yes, there are nuclear reactions constantly occurring in our bodies, but there are very few of them compared to the chemical reactions, and they do not affect our bodies much. All physical objects are made of molecules. A molecule is a series of atoms linked together by chemical (electromagnetic) bonds.
  3. Photon wave phase can also not be directly detected by humans but can be detected by machines called interferometers. Phase information is often used to determine the flatness of a reflecting surface. In summary, humans can indeed see photons. Humans can see all of the properties of photons except for spin and wave phase.
