Answer:

Yes,

Explanation:

Global issue such as global warming can alter the temperatures, cause seasonal precipitation, cause elevated amounts of carbon dioxide and can cause various ecological disturbances such as flooding which prevents the secondary succession to progress.

You decide to focus first on Mutation 1 and Mutation 2.

Answer:

Super-repressor (Is) - Uninducible dominant

Binding region is modified by the protein called repressor which prevents the lactose to bind with it. Thus, even the lactose is present the repressor protein is bound to the promoter and can not be detach from it. Transcription is not inducible.

Promoter mutation (P)- - Uninducible recessive

Mutated promoter region inhibits the binding of RNA polymerase that leads to trranscription.

The lacZ gene ( Z-) is mutated - recessive while the normal LacZ gene (Z +) - dominant .

Inducible (Wild type) No expression (Mutant)

F' lac+/ Is No Yes

F' lac + / P- Yes No

F' lac + / Z- Yes No

F' lac +/ Mutation1 Yes No

F' lac+ / Mutation2 No Yes

Mutation 1 and F' plasmid - Inducible wild type

Mutation 2 and F' plasmid - Mutant no expression

I really don't understand biology someone help me please

BlackZzzverrR [31]

5. they both photosynthesize.
6. they had to be able to get water from their new environment and retain this water. They also had to adapt to reproduction on land (use of pollinators - this is co-evolution)
7. Because those animals are their pollinators.

Select all that apply.

HACTEHA [7]

The answers are;

homeostasis

metabolism

heredity

movement

cells

sensitivity

reproduction

The other characteristics of living organisms include that are not among the choices are growth, adaptation, and interactions. These are characteristics shared by all living organisms whether large or small, complex or simple. They are born by a bacteria(simplest living organism) to humans (complex organisms).

In corn, the allele A allows the deposition of anthocyanin (blue) pigment in the kernels (seeds), while aa plants have yellow ke

lara31 [8.8K]

Answer:

Explanation:

As given,

Allele A for blue anthocynin.

aa for yellow kernel;

at second locus;

W produce smooth kernel,

ww for wrinkled kernel;

Parents as given are: AaWw and aaww

Progeny are:

blue smooth ( AaWw)= 1447;

blue wrinkle (Aaww)= 169;

yellow smooth (aaWw)= 186;

yellow wirnked (aaww)= 1510

Recombinant progeny are 169+ 186= 355

non- recombinant progeny are = 1447+ 1510= 2957

so recombination frequency (RF)= 346/2957×100= 12.0054%

So a and w are linked genes.

They are 12 mu far away from each other.

b) Blue smooth parent= AaWw.

c) Aaww crossed with aaWw

progeny are= AaWw, Aaww, aaWw, aaww,

They all are produced in same proportion =0.25% or 1/4.
