Because everything scientists do or see is put out where the whole world can see. But if they don’t do it accurately then they get proved wrong or even lose their job. And the more accurate an answer is the more opportunity they have to venture and see more Han what they already know.
Answer:
a) All Walnut , Genotype - RrPp
b) Walnut : Rose: Single
1:1:2
Explanation:
Phenotype and their Genotype -
Walnut comb - R_ P_
Rose Comb - R_ pp
Pea Comb - rr P_
Single Comb - rr pp
a) RR PP * rr pp
All progenies will have genotype RrPp (Walnut Comb)
b) Rr Pp * rr pp
RrPp (4), Rrpp (4), rrpp (8)
Walnut : Rose: Single
1:1:2
Answer:
a) DNA fragments associated with histone proteins are all multiple in length (i.e., 260 bp, 520 bp, 780 bp, etc), thereby suggesting the presence of a pattern of organization in the chromatin
b) it suggests that each unit of organization (ie, each nucleosome) consists of 260 bp associated with chromatin proteins
Explanation:
The nucleosome is considered as the basic unit of chromatin. A nucleosome consists of approximately two turns of DNA wrapped around a core of eight histone proteins (i.e., a histone octamer). The histone octamer consists of two copies of each of the histones H2A, H2B, H3, and H4. Moreover, the nucleosomes are connected together by linker DNA sequences which vary between 10 and 100 bp in length.
ATP? Adenosine TriPhosphate
Answer:
As of plants, bioluminescent algae fix carbon dioxide in the presence of sunlight and release oxygen. Further, during this process, they produce light as a part of photosynthesis products. Therefore, the use of bioluminescent algae can reduce anthropogenic carbon dioxide from the environment.
Bioluminescent algae-based lamps are being prepared by scientists to overcome these environmental concerns. Furthermore, these lamps would be used as street lights and reduce energy demands as well (burning of fossil fuels).
