If a homozygous short plant (tt) is crossed with a heterozygous tall plant (Tt), the percentage of tall offsprings is 50% and the percentage of short offspring is 50%.
- A heterozygous tall pea plant will have the genotype "Tt" and a homozygous short pea plant will have the genotype "tt" because homozygous means that both alleles are identical.
- Since 'T' is dominant over 't', any plant with at least one "T" allele will be tall (the dominant trait), regardless of what the other allele is.
- The punett square of the following problem will have 2 squares with Tt genotype and 2 squares with tt genotype.
Hence, the genotypic ratio of F1 generation will be
Tt : tt
1 : 1
And phenotypic ratio of F1 generation will be
Tall : Short
1 : 1

Answer:
Chances are, you haven't infected the bacteria in a hospital setting or surgery, as you could have contacted them anywhere.
What happened with said patient was the face of the immunosuppressive treatment, the defense of the patient was decreased and it generated a worse picture with a bacterium that would not act in such a pathogenic way in another person who does not receive corticosteroid treatment.
This deduction could be made since prior to pneumonia and meningitis there were other infections that occurred in the patient indicating immunosuppression or lowered immunity, which were alerts for professionals.
Explanation:
The immunosuppression generated by corticosteroids is an adverse effect of said drug, thus causing bacteria or other pathogenic microorganisms to more easily generate lethal diseases that occur, similar to the human immuno-insufficiency syndrome.
These pneumonias and meningitis are very common in children but not in adults, which means that the defense of acquired immunity throughout life would not be serious.
In patients like these where corticosteroids suppress the path of humoral defense factors, thus inhibiting the presence of COX and thromboxane A2 in the immune lineage, that is why the immunological tests are weakened and the bacteria have more spread or harmful effects such as this patient.
The bacterium does not indicate that it is intra-surgical or hospital-based because of the severity of the disease it triggered, but because the patient is immunosuppressed.
This level of direct harvesting could cause the ecosystems to be severely damaged. The correct option among all the options that are given in the question is the second option or option "B". This type of fishing can disturb the natural balance and ultimately several species might vanish from our earth.
Photosynthesis is how plants eat. plants/single cell organisms absorb sun light and transfer it into food/energy that it can use, phytoplankton for example use photosynthesis to eat, and they produce oxygen as a by-product of the photosynthesis. Trees and other plants to the same thing.
Answer:
Option D, oxidized
Explanation:
The NADH gets oxidised when it passes its electrons into the Electron Transport System
Oxidization is a process in which one element or compound loses its electron to other chemical element or compound thereby itself getting oxidised and reducing the other one (the one who gains the electron).
Here in the electron transport system, the NADH loses or donates its electron to the Electron Transport System thus chemically it gets oxidized.
Hence, option D is correct
