Puritan disagreement over the use of inoculations for smallpox reflected tensions over what broader issue?
Vadim26 [7]
<h2>Smallpox Vaccine</h2>

Explanation:

  • The smallpox vaccine  is the best way to forestall smallpox.
  • The immunization is produced using an infection called vaccinia, <em>which is another pox-type infection identified with smallpox. </em>
  • Immunization began as a technique for the anticipation of smallpox by conscious presentation of material from smallpox pustules into the skin.
  • This for the most part delivered a less extreme contamination than normally procured smallpox, yet at the same time initiated invulnerability to it.  
  • It created insusceptibility as a rule, however it likewise murdered a few people and added to smallpox outbreaks.

3. a) What are three ways for materials to move in and out of cells? (6 points)
zalisa [80]
Answer: Diffusion, Osmosis and Active Transport
Explanation:
The processes of transport between the cell and the external environment can be grouped into groups: Passive Processes - occur through the plasma membrane, without energy expenditure to the cell, to equalize cell concentration with the external medium. Examples of such processes are diffusion, facilitated diffusion and osmosis. Active processes - occur through the plasma membrane, with energy expenditure, maintaining the concentration difference between the cell and the external environment. For example, sodium-potassium pump. Diffusion In diffusion, particles move from the highest concentration medium to the lowest concentration medium, so that it can be distributed throughout the medium. Therefore diffusion is a process called passive transport. Facilitated Diffusion is the passive transport of substances across the plasma membrane, without wasting cell metabolic energy, allowing the passage of substrates (molecules or ions) from a more concentrated to a less concentrated medium through specific mediation of carrier proteins, enzymes carriers or permeases along the plasma membrane. This process is mainly used to transport carbohydrates, amino acids, vitamins and some ions: sodium, potassium, calcium. Osmosis is the name given to the movement of water between media with different concentrations of solutes separated by a semipermeable membrane. It is an important physicochemical process in cell survival.
The sodium-potassium pump is an example of active transport. Sodium concentration is higher in the extracellular environment while potassium is higher in the intracellular environment. Importantly, the energy required for this change comes from the breakdown of the ATP (adenosine triphosphate) molecule into ADP (adenosine diphosphate) and phosphate. The sodium (Na +) ion in the cytoplasm is pumped out of the cell. In the extracellular medium, the potassium ion (K +) is pumped into the internal medium. If there was no efficient active transport, the concentration of these ions would equal. Thus, the sodium and potassium pump is important as it establishes the difference in electrical charge between the two sides of the membrane that is critical for muscle and nerve cells and facilitates the penetration of amino acids and sugars.

who usually gets chemotherapy, is there a specific group that it is more common in (children , the elderly , etc)​
kondor19780726 [428]

Answer:

elderly, specifically 50-74.

Explanation:

According to macmillan.org, the risk for cancer increases with age.

https://www.macmillan.org.uk/information-and-support/...cancer/what-is-cancer.html

If we are to go off of percentages, I would say a higher percent of children (per capita) get chemo, as it is a lot harder to say, "oh well i will die soon anyways" with a child.

lubasha [3.4K]

Answer:

For example, if the seeds that the bird needs to eat is bigger, over time it will adapt to get a bigger beak to eat the bigger seed. The birds that have adapted reproduce and soon more and more birds that have a bigger beak for the bigger seed are more common. If the type of food available changes than the bird will most likely adapt to eat that food.
