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
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.

Explanation:
name the gas which is produced during respirated
Answer:
When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere. This carbon dioxide is a waste product produced by the animal's cells during cellular respiration. Cellular respiration occurs in the individual cells. Digested foods have chemical energy stored in them.

Variation in genotype is caused by
O None of the above
e phenotypes changing more quickly than genotypes.
o recombination of genes as a result of sexual reproduction.
O
O mutations only.
Answer:
Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Another source is gene flow, or the movement of genes between different groups of organisms. Finally, genetic variation can be a result of sexual reproduction, which leads to the creation of new combinations of genes.

Choices: bronchi, nasal cavity, capillaries, trachea, pharynx, aveoli, bronchioles
Answer:
Nasal Cavity, Pharynx, Trachea, Bronchi, Bronchioles, Alveoli and Capillaries.
Explanation:
We first breathe in the air through our nose so it goes through our nasal cavity. After that it goes down our throat past the pharynx (voice box) and through the trachea (windpipe). From here it arrives in our lungs via the bronchi, which then splits into smaller bronchioles which have alveoli at the end of them. The alveoli then have small capillaries which the oxygen goes into so it can travel around the body through the bloodstream.

After fertilization, the successful development of a mature, full-term fetus depends on A. The release of human chorionic gonadotropin (hCG) by the developing placenta AND the production of estrogen and progesterone by the placental tissues B. the release of human chorionic gonadotropin (hCG) by the developing placenta C. maintenance of the corpus luteum for all 9 months D. all of these E. the production of estrogen and progesterone by the placental tissues
Answer:
The correct option is A (The release of human chorionic gonadotropin (hCG) by the developing placenta AND the production of estrogen and progesterone by the placental tissues).
Explanation:
The developing placenta release Human chorionic gonadotropin (hCG) during pregnancy. What this hormone does is tell the body (corpus luteum) to produce progesterone to maintain the pregnancy. The presence of Human chorionic gonadotropin is a sign of pregnancy, meaning successful fertilization had happened, and implantation of the embryo had occurred too, preventing another cycle of menstruation.
The successful development of a mature, full-term fetus also depends on estrogen which during pregnancy aids the formation of blood vessels and also aids fetal maturation. While progesterone is a hormone when released during pregnancy helps maintain a healthy pregnancy.

Generally, the more a food has been altered from its original form, the less healthy it
is.
A.) True
B.) False
Environmental impact has also been seen through human activity with agriculture. This is due to the high amounts of monoculture farming. Although having large agricultural fields of one crop can be efficient, it results in attracting a higher number of pests, which, in turn, results in a high use of pesticides. Identify a solution that would possibly remedy this issue and explain why that action would be beneficial.
Explanation:
Pesticides, fertilizers and other toxic farm chemicals can poison fresh water, marine ecosystems, air and soil. They also can remain in the environment for generations. Many pesticides are suspected of disrupting the hormonal systems of people and wildlife. Fertilizer run-off impacts waterways and coral reefs.
