Answer:
Decrease the pumping of NADPH across the thylakoid membrane
Decrease of flow of electrons from photosystem II to photosystem I
Explanation:
Thylakoids are defined as a membrane-bound compartments located inside the chloroplasts and the cyanobacteria. Here, light-dependent reactions of photosynthesis occurs.
To block the photosynthesis process, the herbicides pushes the dichlorophenyl dimethylurea to block the electron flow through the photosynthesis II and it reduces the flow of electrons from photosystem II to photosystem I. It also decreases pumping of the NADPH across the thylakoid membrane.

when a tautomeric shift occurs, what is true about the resulting mutation?
When a tautomeric shift occurs, then the resulting mutation ALWAYS changes a purine to a purine or a pyrimidine to a pyrimidine. A tautomeric shift may lead to a point mutation.
A mutation is any alteration in the nucleotide (DNA) sequence of the genome of an individual.
A tautomeric shift can be defined as a temporary change in the nucleotide base structure.
A transition mutation is a point mutation of one purine or pyrimidine base pair to the other purine/pyrimidine that occurs when one nucleotide base undergoes a tautomeric shift during DNA replication.

Mountain chains in northern Europe and West Africa match the Appalachian Mountains in terms of their ages and the sequences of rock layers that make them up. in 3-5 sentences analyze these observations and explain what conclusions can be drawn from them.
The above observation shows that the mountain chains in Northern Europe and West Africa are part of the Appalachian Mountains as a result of the same age, matching of rocks, etc
A mountain chain simply means a row of high mountain summits or a contiguous ridge of mountains within a larger mountain range.
The theory of plate tectonics establishes a co-relation with these mountain chains by understanding their movements. It was shown that Europe and Africa were part of the same landmass in the past. Due to the gradual movement of plates, both continents move apart.

A test cross performed between the individual with unkown genotype and the h0m0zyg0us recessive individual. 9) hh. 10) Hh or HH. 11) HH x hh. 12) 100% Hh. 13) Hh x hh. 14) 50%Hh and 50% hh. 15) -16) in the text.

Available data:Single diallelic gene codes for hair in Guinea pigsAllele H is dominant and codes for having hairAllele h is recessive and codes for not having hair
For this gene we will assume complete dominance, meaning that the dominant alele completely hides the expression of the recessive allele.
According to this information, we can say that
Genotype Phenotype
HH Hairy pig
Hh Hairy pig
hh Hairless pig
9) Geneviene does not have hair ⇒ Its genotype is hh
10) Fred has hair ⇒ Its genotype is HH or Hh
Possible crosses
11 and 12)
Cross1: If Fred was genotype HH and bred with Genevieve
Parentals) HH x hh
Gametes) H H h h
Punnett square) H H
h Hh Hh
h Hh Hh
F1) 100% of the progeny is expected to have hair and be heter0zyg0us, Hh.
13 and 14)
Cross2: If Fred was genotype Hh and bred with Genevieve
Parentals) Hh x hh
Gametes) H hh h h
Punnett square) H h
h Hh hh
h Hh hh
F1) 50% of the progeny is expected to have hair and be heter0zyg0us, Hh.
50% of the progeny is expected to be hairless and be h0m0zyg0us recessive, hh.
15)
• If the individual with the unknown genotype (Fred) is heter0zyg0us, the phenotypic rate of the descendants is 50% heter0zyg0us -Hh- and 50% h0m0zyg0us recessive -hh-.
• But if the individual with the unknown genotype is h0m0zyg0us dominant, the phenotypic rate of the descendants is 100% heter0zyg0us for the trait, Hh.
16)
The weakness is that even if Fred is heter0zyg0us for the trait, when making the cross it might occur that all individuals in the progeny are born h0m0zyg0us recessive, and there is a risk of missinterpreting the results.
So in that situation, many crosses must be done between fred and genevieve to se sure about Freds genotype.

Because they have a wide surface area to speed up absorption, root hair cells are designed to absorb water and mineral ions.
What is the role of root hair cells in plants?Plants are anchored by root hairs that emerge from the surface of the soil and take up water and minerals.
Vascular tissue in the heart of the root transports food produced in the leaves to the root, while transporting water and minerals away from it.
Its main purposes include anchoring the plant, absorbing water and dissolved minerals and transferring them to the stem, as well as storing reserve food.
Water and nutrients are mostly taken up by root hairs from the rhizosphere.
Therefore, root hair cell have large surface area that enable the cell to carry out its function.
