Flowering Locus C (FLC) is a gene that is responsible for flowering in certain plants. FLC is expressed in new seedlings, which prevents flowering. Upon exposure to cold temperatures, FLC expression decreases and the plant flowers. FLC is regulated through epigenetic modifications. What type of epigenetic modifications are present in new seedlings and after cold exposure

Answers

Answer:

- New seedlings: histone acetylation

- After cold exposure: histone methylation

Explanation:

Vernalization is an adaptive mechanism whose objective is to ensure that flowering occurs only after winter (i.e., after cold conditions). In certain plants, this process (vernalization) suppresses the expression of genes that encode repressors of flowering. In Arabidopsis, vernalization is associated with histone modifications at FLC chromatin. The FLOWERING LOCUS C (FLC) is a MADS-box gene that acts as a repressor of flowering in Arabidopsis. Epigenetic modifications control the expression of the FLC gene. The FLC gene is expressed at low temperatures due to histone acetylation at FLC chromatin, and thereby the expression of FLC mRNA transcripts ensures that the Arabidopsis plant cannot flower. Subsequently, as the Arabidopsis plant is exposed to cold, FLC is repressed by the accumulation of trimethylation on lysine 27 of histone 3 (H3K27me3), thereby allowing it to flower when temperatures become warmer.

Answers

Answer: Lipid refers to any class of organic compounds that are considered fatty acids. This also includes their derivatives that are soluble in organic solvents, like many natural oils, waxes phospholipids and steroids.

All lipids have similar properties because their molecules are made of the same elements with similar chemical structure that only varies slightly.

Foods like meat, poultry, seafood, beans, peas and eggs are all sources of proteins, while good that contains saturated fat like palm oil, coconut oil, milk, cheese and coffee creamers and butter contain lipids, that may help in storing energy.

It will be true, since the ice bergas that fall off can be as big as a 98-164 feet. Form what I have resched

It is False. Because the volume of water they displace as ice is the same as the volume of water they add to the ocean when they melt. So the sea level does not rise when sea ice melts.

What are coral reefs?

Coral reefs are narrow and shallow stretches land where corals ate found and these corals serves as foundation for reefs to form.

The reef is an ecosystem consisting of algaes and fishes as well as some other aquatic organism.

The balance in coral reefs can be disrupted by human activities such as:

Name three reasons why the atmosphere is important to life on earth and explain your reasoning.

Answers

The atmosphere ensures that all living things can carry out daily processes that are vital to survival, such as breathing. Photosynthesis, for example, could not be possible without an atmosphere, because all of the gasses in our atmosphere stay there due to Earth's gravity.

The atmosphere is vital because it plays a role in the water cycle as well, allowing rain to keep falling and giving life-giving water to organisms that need it.

Life would not be possible without an atmosphere on this planet, along with other vital things, like gravity, sunlight, and water.
