Ball and Socket Joint
This type of joint allows for a wide range of rotation and movement. The shoulder and hip are ball and socket joints.
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.
Answer:
Exposure to a virus is closely related to the development of immunity, since the immune system is responsible for creating antibodies in response to the presence of potentially harmful biological agents, such as these viruses.
Explanation:
Viruses are biological agents that can produce diseases when they enter the body of a living being.<u> In response to contact with a virus, the</u><u> immune system</u><u> synthesizes specific </u><u>antibodies</u> to combat the foreign biological agent.
Antibody immunity can be of two types. It is fast when it is mediated by immunoglobulins M (IgM), which attack the virus anywhere, while the late and prolonged response is due to the development of immunoglobulins G (IgG).
An example of immunity to a virus occurs with the exhibition to the virus of the Dengue, that creates permanent immunity to the viral serotype to which an individual is exposed.
The acquired immunity, mediated by antibodies, is the base for the development of vaccines.
Answer:
The endosymbiotic theory
Explanation:
Protists are the multicellular organisms which possess characteristics of both the prokaryotes and eukaryotes.
The protist can derive nutrition by either heterotrophic mode or photoautotrophic mode. This variation could exist within the same genus and same species.
This variation could be explained with the endosymbiotic origin of the organisms as some species could engulf the photosynthetic bacteria whereas some could have engulfed the chemosynthetic bacteria.
This can be observed in the green and red algae which depend on a different mode of nutrition belonging to the same group.
Thus, the endosymbiotic theory is correct.
Atp energizes other molecules in cells by transferring a phosphate groups to those molecules.
<h3>What about phosphate group?</h3>
- A functional group that has an atom of phosphorus linked to four atoms of oxygen (three single bonds and one double bond).
- If there isn't a link between one of these oxygen atoms and another atom, the structure is a phosphate ion.
- Proteins require phosphate groups to be activated in order to carry out specific tasks in cells.
- The process of phosphorylation, which involves the addition of a phosphate group, activates proteins.
- All living things phosphorylate proteins at some point.
- Bone and teeth are formed with the help of phosphate.
- Additionally, phosphorus is a component of a number of essential compounds, such as those that the cell uses for DNA, cell membranes, and energy (deoxyribonucleic acid).
- Phosphorus is a mineral that the body gets from food and excretes in urine and occasionally stooll.
- The part of the DNA double helix that gives the molecule's structure support is known as the phosphate backbone.
