Answer:
Recessive phenotype plant
Explanation:
If the plant has recessive genotype then it will be easy to identify because it will have the recessive phenotype. However if the plant has dominant phenotype it can either have homozygous genotype or heterozygous genotype. To confirm if the plant is homozygous or heterozygous, a test cross can be done with plant having recessive phenotype.
If our test plant is homozygous dominant, it will pass one dominant allele to the next generation and all the offspring would have dominant phenotype. If our test plant is heterozygous dominant it will pass one dominant allele to half of the offspring and one recessive allele to another half so 50% of next generation will have dominant phenotype and other 50% will have recessive phenotype.
Hence by test cross (cross with recessive phenotype plant) it is possible to determine the genotype of the uncharacterized pea plant.
Inner membrane of the chloroplasts
Explanation:
The present day eukayrotes are all considered to be derived from its original ancestor – the cyanobacteria.
Earlier, photosynthesis by the first photoautotrophs took place utilizing hydrogen sulphide as the electron donor. However, it was later when the cyanobacteria, which were originally residing in the mitochondria of an eukaryotic cell under an endosymbiotic relationship, developed into true chloroplasts, the use of water as electron donor to perform photosynthesis began.
The cyanobacteria were aerobic in nature and required oxygen to survive. They evolved the chloroplasts covered with an external protective membrane and an internal membrane. It is the internal membrane which contains all the necessary organelles or components necessary for photosynthesis like thyllakoids, stroma etc which helped them to utilize water as an electron donor during photosynthesis like all the eukaryotes.
Answer:
Oxygen.
Explanation:
Oxygen molecule that is produced in the light dependent reactions. This shutting down of linear electron flow greatly affected the production of oxygen. Photosystem II gains replacement electrons from splitting of water molecules into hydrogen ions (H+) and oxygen atoms so if the electron flow is disturbed then oxygen production is greatly affected.
In a particular context, “epoch” can refer to a particular point of time characterized by a particular event/series of events.
While “era” refers to a period of time characterized by events in a chronological order.
Thus, an “era” can encompass more than one “epoch”.
“Period” can refer to a short interval of time or a very long interval of time.
For example:
<span>“My period of happiness….”“The period of Four Horsemen…”</span>
<span>“Eon” </span>refers to an indefinitely long time. <span>Eon is presumed to consist of at least 2 eras.</span>
Answer:
No it is not a scientific theory.
Explanation:
An explanation of any aspect of the natural phenomenon of the world that can be tested several times and well supported by the evidence, and follows the scientific method. Furthermore known as scientific theory.
Presently, a logical hypothesis must meet a few rules, and one of those is that it must be upheld by a few (and free) strands of proof.
For this situation, we have just one hypothesis, that bulldogs are great pet and Meatball is great among bulldogs, and it isn't sufficient, at that point it can not be a scientific theory.
