The cells of certain eukaryotic organisms, such as vertebrates and plants, often methylate the cytosines in their DNA, producing
stich3 [128]

Answer:

The G-T mismatches generally originate because of the spontaneous deamination of 5-methylcytosine to thymine. Therefore, correcting G-T to G≡C most probably preserves the original sequence.  

In the DNA, the 5-methylcytosine usually goes through the process of deamination to thymine. This transformation may cause a G-T base pair or mismatch of nucleotide pairs. Generally, the mutation like C-T transition is common. The G-T base pair is identified by base excision repair proteins, which withdraws this mismatched base pair.  

The repair system encourages methylation of cytosine as the mechanism of the regulation of transcription, which permits the turning off or on the process of transcription on the basis of the requirement of the cells. This also assists in preventing the mutation of DNA.

Rank the biomes in terms of how much you expect plant growth to increase as a function of increased co2 in the atmosphere.
Lelechka [254]

The following are the expected ranks of biomes  based on increased oxygen for plant growth and they are

1. Desert,

2. Grassland

3.  Temperate Forest

4. Tropical Rain Forest

The desert biome is formed owing to very limited annual rainfall and it covers approximately 20% of the Earth.  The Grassland is predominantly dominated by grasses while the temperature in the temperate forest is around 10 degree celcius. The plants and trees in this biomes develop special adaptations for their survival. However, the rain forest is characterized with all year round rain hence the biome is moist. The biome is known for vegetations with dense canopies.

Identify the organelle with the following structure or function from the list below:
Mila [183]
The organelle you're looking for should be cholorplasts.

Chloroplasts are double membrane bound organelles, which is important for the process so photosynthesis. The outer membrane is smooth and gives the shape of the chloroplast, while the inner membrane forms sac that contains chlorophyll inside.

Chloroplasts exists in green plants that photosynthesize for energy, and they appear the most in mesohpyll cells, a type of cells in leaf.

While Maria's mom has small ears (alleles ee), her dad has large ears (alleles EE). What are the possible phenotypes Maria would
Svetach [21]
The only possible phenotype is large ears.

This is because using a punnet square reveals that each option has a dominant allele of large ears, leaving no room for the recessive trait of small ears.

Hope this helps!
