The causes may include the species that are native to that place could suffer a lack of food the food chain can become imbalanced and the non-native species could kill of the native species or destroy the natural environment
Answer:
a. pipette
Explanation:
The instrument used in the laboratory for measuring base is the pipette.
It is used to suck up the right amount of base for experimental purpose.
- The burette is used for measuring and holding the acid.
- The pipette is often used alongside a burette, conical flask and retort stand during a titration reaction.
- The pipette is a narrow cylindrical pipe usually made up of some special glass.
- It should be handled with caution as it is a very fragile device.
Assumptions:
1. Equilibrium has been reached for the allele proportions
2. Absence of <span>evolutionary influences such as </span>mate choice<span>, </span>mutation<span>, </span>selection<span>, </span>genetic drift<span>, </span>gene flow<span> and </span>meiotic drive<span>.

Defining L=long stem, l=short stem, and L is dominant over l.
f(x) = frequency of allele x (expressed as a fraction of population)
Then the Hardy-Weinberg equilibrium law applies:
p^2+2pq+q^2=1
where
f(LL)=p^2
f(Ll)=2pq
f(ll)=q^2
Given f(ll)=0.35=q^2, we have
q=sqrt(0.35)=0.591608
p=1-q=0.408392
=>
f(Ll)
=2pq
=2*0.408392*0.591608=0.483216
= proportion of heterozygous population
Answer: percentage of heterozygous population is 48.32%
Horticulturalist’s best option is clone the desired tulip so there will be no genetic variations.
Explanation:
Cloning is a process by which replica of organism is made without having any genetically variations. It is done carefully to avoid any variations in the office bring that may be related to physical or genetic structure.
The process of cloning should be done under the supervision of expert to avoid any error which could lead to the variation in genetic structure. It is very necessary for the amateur horticulturalist who desires to have dual apps without any genetic variation to perform cloning.
