Mucous membrane, membrane lining body cavities and canals that lead to the outside, chiefly the respiratory, digestive, and urogenital tracts. Mucous membranes line many tracts and structures of the body, including the mouth, nose, eyelids, trachea (windpipe) and lungs, stomach and intestines, and the ureters, urethra, and urinary bladder.
There are a few differences between animal cells and plant cells.
Plant cells have cell walls, and animal cells do not.
Plant cells have a large central vacuole and animal cells do not.
But probably the most recognizable (and probably the one your question is asking about) is the chloroplast. The Chloroplast is the home of chlorophyl, a green pigment plants use to make energy.
Answer:
Acetylation of histone tails is a reversible process.
DNA is not transcribed when chromatin is packaged tightly in a condensed form.
Methylation of histone tails in chromatin can promote condensation of chromatin.
Acetylation of histone tails in chromatin allows access to DNA for transcription.
Eukaryotic chromatin structure is a highly complex assembly which needs to be simplified in order to undergo process of transcription. Eukaryotic chromatin structure is highly condensed in nature and DNA cannot be access for transcription. Actylation of histone tails is a process in which breaks the bond of attraction between adjacent nucleosomes. It results in chromatin being condensed attains a loose form. Transcription of DNA can occur in a loose chromatin. Methylation can promote condensation or decondensation of chromatin structure depending upon the methyl group present in the histone.
Answer:C) Traits like this are determined by the genes passed from parents to their children.
Explanation: Every trait in an organism is controlled by a pair of gene. A gene that controls a trait usually have two alleles. During fertilization, for every pair of gene one allele is inherited from the mother while the other allele is inherited from the father and the two alleles come together to form a pair of gene. Every trait in an organism is determined by genes that are passed from the parents to the offsprings.
Oil Coal and Natural Gas are the fossil fuels the USA has the most reserves of. Given that only one of them is on the answers Coal is the correct answer.
