Answer:
This is an example of directional selection.
Explanation:
Directional selection is a type of positive selection where the evolutionary fitness of one genotype is higher compared to the other ones, thereby favoring the selection of one particular phenotype and shifting allele frequencies towards the selected genotype. In a biological context, the directional selection increases the chances for surviving and for reproducing in those organisms that have the alleles favored by this type of selection. Thus, the directional selection produces the loss of genetic variability and leads to the fixation of the dominant alleles.
Answer:
Used the C1V1 = C2V2 method for calculations
Explanation:
Component Calculation Volume of Stock to be added
FBS: 100*V1 = 10*25 2.5 mL
Glutamine: 200*V1 = 2*25 0.25 mL
Penicillin: 10000V1 = 100*25 0.25 mL
Streptomycin: 10000V1 = 100*25 0.25 mL
NB: C1 = Stock Concentration; V1 = Volume of stock required; C2 = Final concentration required; V2 = Final volume required
Answer:
Treating the affected area with an alkaline solution or substance such as baking soda.
Explanation:
Neutralization Reaction:
- When an acid and an alkali react chemically, they form water and a corresponding salt. This reaction called the neutralization reaction.
- acid + base (alkali) → salt + water
- E.g HCl + NaOH → NaCl + H2O
- The formic acid that the ant injects can be neutralization by application of an alkali.
- In order to prevent a serious allergic reaction, antihistamines must also be administered.
The ammonia makes the water more acidic so get a filter
