An experimental herbicide kills plants by blocking the ATP synthase in thylakoids. This is most likely to: Group of answer choices Decrease the pumping of NADPH across the thylakoid membrane Increase the pH of the chloroplast stroma Decrease of flow of electrons from photosystem II to photosystem I Decrease the concentration of ATP in the thylakoid space
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.

Which is an example of genetic drift?
Answer:
Explanation:
Genetic drift, gene flow, mutations, and natural selection are responsible for the change in the gene pool over time. Example of genetic drift: a population of rabbits with alleles B and b, both alleles are present in equal frequencies p = 0.5 and q = 0.5 if 10 parents reproduce the probability of having an offspring with alleles B or b is 0.5; however, by chance, a slight difference in the offspring allele frequency might occur due to random sampling. As a result, in the next generation, the allele frequencies will change slightly to new frequencies by chance to become p = 0.4 and q = 0.6. in the following generations, the random sampling of alleles continues and the change in allele frequency will be greatly different from the initial 0.5 frequency due to genetic drift. Even though genetic drifting is one of the factors that participate in the evolutionary process of the genetic pool by increasing or decreasing a certain allele’s frequency, however, it does not influence the adaptation of individuals to the environment since the affected genes may be harmful or beneficial genes.

Use an examples to distinguish dominant and recessive phenotypes.
I'm a bit stuck and need some help. Much appreciated!
Think recessive phenotypes as paper and dominant phenotypes as teared paper. Once paper is teared, it can't be fixed. Not even tape. It'll just leave that mess exposed. Same with dominant phenotypes. It just takes one dominant trait to change the looks of future offspring.
If you don't tear the paper, everything is fine. Same with recessive phenotypes. As long as there's no contact with any dominant phenotypes, the looks of future offspring will change.

If an individual has trisomy resulting in Down syndrome and has an extra chromosome in each cell, what mutation must have occurred?
A. A nondisjunction mutation in the gamete of one of the parents
B. A nondisjunction in both gametes of the parents
C. A nondisjunction in one of the first gamete cells of the individual
D. A nondisjunction mutation in body cells of both parents
Answer:
if An individual has an extra chromosome in every one of its cells, the mutation that must have occurred is A non-disjunction mutation in the gamete of one of the parents
If an individual has trisomy resulting in Down syndrome and has an extra chromosome in each cell, the mutation that must have occurred is A. A nondisjunction mutation in the gamete of one of the parents.
Down syndrome simply means a genetic disorder that is caused when there's an abnormal cell division that then leads to extra genetic material.
The effect of Down syndrome is the fact that it leads to an intellectual disability, developmental delays, and a distinct facial appearance.
The mutation that has occurred with someone that has a Down syndrome is the nondisjunction mutation in the gamete of one of the parents.

Answer:
3. In the two-kingdom classification following are drawbacks:-
The plants comprised of photosynthetic and non-photosynthetic species. Fungi, that feed on dead organic matter, were placed under photosynthetic plants. There was another class of classification needed were the organisms with the same characteristics were clubbed into one kingdom. This system did not distinguish between the eukaryotes and prokaryotes, unicellular and multicellular organisms and photosynthetic (green algae) and non-photosynthetic (fungi) organisms. There are some organisms which neither fall into plant nor animal kingdom like Lichens.Explanation:-

A pseudogene is a Group of answer choices second copy of a gene that functions when the original copy becomes damaged. gene that is unrelated in sequence to another gene but has the same function. gene that evolved by gene duplication and the acquisition of mutations to yield a gene product that has a slightly different function from that of the original gene product. gene that arose through gene duplication, but by acquiring mutations became nonfunctional.
Answer: Gene that arose through gene duplication, but by acquiring mutations became nonfunctional.
Explanation:
A gene is a functional unit of heredity formed by DNA. They possess a sequence of nitrogenous bases that during translation is read by ribosomes to produce molecules called proteins. A pseudogene is a DNA sequence that resembles a gene, but which has been inactivated in the course of evolution by mutations in its sequence. Thus, it is a gene that derives from other known genes and whose functions are different, may have lost their functionality or have radically changed it. To this day, it is not known exactly how pseudogenes are created, however some theories are as follows:
1. A gene duplication can generate two copies of a gene when only one is needed. A mutation would then occur that deactivates one of the copies. In addition, the duplication event may not be complete, so that the copy has incomplete promoters.
2. They may be fragments of the messenger RNA transcript of a gene may be spontaneously reverse transcribed and inserted into the chromosomal DNA. They lack the promoters of normal genes, so they are not expressed normally.
3. A gene may become non-functional or inactivated if such a mutation becomes fixed in the population. This can occur by normal means such as natural selection or genetic drift.
