Answer:
genotypic ratio = 2:2
Explanation:
We were being told that when Mendel crossed yellow- seeded and green- seeded pea plants, all the offspring were yellow seeded.
This implies that the Yellow seed trait masked the green seed trait in the F1 generation. The best defination that can be deduced is that;
the yellow-seeded plants are homozygous dominant &
the green-seed pea plants are homozygous recessive
So, let yellow- seeded pea plants= YY
and green- seeded pea plants= gg
i.e YY × gg
| Y | Y
g | Yg | Yg
g | Yg | Yg
F₁ = (Yg, Yg, Yg, Yg,) All the offspring were heterozygous yellow seeded plant.
Now, when he crossed the F₁ heterozygous yellow seeded plant with the green- seeded plants; we will have the following result
i.e Yg × gg
| Y | g
g | Yg | gg
g | Yg | gg
F₂ = (Yg, Yg, gg, gg)
The F₂ generation would have genotypes of (Yg, and gg) and a genotypic ratio of 2:2
In this example, the biosphere is very dependent on the hydrosphere.
Pollution is an ecological disturbance and turmoil that ruins and endangers life either in land or sea, even air.
Three types of pollution exist:
Water pollution
Air pollution
Land pollution
Answer:
a. Reduced siRNA-mediated mRNA degradation
Explanation:
The TRBP (transactivation response element RNA-binding protein) is an RNA-binding protein that forms the Dicer complex, which is involved in epigenetic pathways such as those mediated by the RNA interference (RNAi) mechanism. RNAi is a key process where small non-coding RNAs such as, for example, small interfering RNAs (siRNAs) and microRNAs (miRNAs) can inhibit target gene expression at posttranscriptional level by different mechanisms (including the degradation of target mRNAs). A null mutation of this cofactor will alter the Dicer complex, thereby also affecting RNAi pathways mediated by small interfering RNAs.
Answer:
they are the same that's y you don't have to compare them
Explanation:
after the fact that you are not actually involve it
Answer:
The correct answer is: Pupil.
Explanation:
- Light enters inside the side through a small opening in the iris of the eye which is called the Pupil.
- The outer most part of the eye Cornea and the outer chamber aqueous humor are both transparent and allow light to refract through them.
- The Iris, which a circular and thin comes next to the cornea and aqueous humor. It is reponsible for regulating the amount of light that can reach the retina by altering the pupil size.
- The change in the size of the pupil is mediated by muscles in the iris.
- There are two types of muscles, radial muscles and circular muscles.
- In bright light, the radial muscles of the iris relax while the circular muscles contract. This decreases the pupil size allowing less light to pass into the retina.
- In dim light, radial muscles of the iris contract while the circular muscles relax. This increases the pupil size allowing more light to pass into the retina.
