Elements from the halogen group including F, Cl, Br have pretty high electronegativities. The most electronegative element is Fluorine with a score of 4.0 (the highest possible.)
Across from Fluorine we also have N and O with high electronegativities.
Electronegativity is basically how much elements 'want' electrons. A simple way to think about it is that the closer an element is to Fluorine, the higher its electronegativity is.

Eosin-methylene blue agar, or EMB, is a commonly used bacteriological medium for growing gram-negative bacteria from complex env
oksano4ka [1.4K]

Answer:

Differential and selective

Explanation:

A selective media is one used for growth of only selected microorganisms. Since this medium is using methylene blue to inhibit gram-positive bacteria and allowing the growth of gram-negative, then we can cathegorize it as selective. Selective growth media is also used in cell culture to ensure the survival or proliferation of cells with certain properties, such as antibiotic resistance or the ability to synthesize a certain metabolite, so the researchers can study or farm said metabolite or an specific reaction to an antibiotic.

Meanwhile, a differential media, also called indicator media, distinguish one microorganism type from another on the same media. This is done through biochemical characteristics which reacts to specific nutrients or indicators (neutral red, phenol red, eosin y, or methylene blue) added to the medium to visibly indicate the defining characteristics of a microorganism. Since this media is changing colors when the acidic concentration increases, it is a differential media as well.

What are two issues with Lamarks theory of evolution!!!<br><br> I will mark brainest!!!!! Pls
Mkey [24]

Answer:

  • If it were true, all organisms would be complex and simple organisms would disappear
  • It does not account for genetic mutations known to affect physical traits

Explanation:

Lamark's theory of evolution is that changes in the organism's physical form during its lifetime can be passed on to its offspring.  In other words, he believed that children can inherit acquired characteristics from their parents.

The classic example is that he believed giraffes evolved long necks because they would stretch upwords to eat leaves from tall trees, elongating their necks, and then would pass on a longer neck to its children. Or in humans, that a body builder would make a muscular child because of their intense training!

There are a few problems with this theory:

  • If we believe this theory, organisms would always be getting more and more complex and 'improved', so simple organisms would disappear.
  • We know that changes to the DNA influence inherited physical characteristics, not simply continued use

1."Evolution is natural selection and natural selection is evolution". Is it a true or false statement. Give an explanation for
schepotkina [342]
1. true. natural selection keeps the more suited traits which makes them more adapted to environment (evolving over time).
2. you would expect human DNA to be close to a tiger because they are both mammals.
3. mutations are the raw material for evolution.
4. a cell
5. survive and reproduce

Kitty [74]

Answer:

Neural Plasticity

Explanation:

  • The ability to change the form and function of the neurons in response to the changes that takes place in the environment is termed as neural plasticity.
  • Due to neural plasticity, the brain has the capability to change throughout the life of an individual.
  • Neural plasticity is important for the optimum working of the brain.
  • The environmental stimulation that takes place during childhood alters the circuitry of the brain and hence, contributes to the intelligence of the child and this alteration in the circuitry with respect to he environmental stimulation is an example of neural plasticity.
