The answer is In the tunica, cell divisions are perpendicular to the stem axis, giving rise to thick layers of <span>tissues covering the outside of the tip. </span>
The tunica is a membranous structure which covers the plant organs. It is responsible for the characteristics of leaf edges and margins in the monocots. During the plant growth, perpendicular cell divisions regarding the stem axis result in the membranous<span> structure outside of the tip.</span>
Explanation:
Surprisingly, until recently, not much was known about the genes that control melanin production. 6 were known (MC1R, TYR, OCA2, SLC24A5, MATP and ASIP) and 17 more have been recently identified (DTNBP1, GPR143, HPS3, KITGL, MLPH, MYO5A, MYO7A, SLC45A2, TYRP1, ERCC6, GNAS, HERC2, IRF4, OBSCN, SKC24A5, TPNC2 and MITF), all of them directly or indirectly related to the process of melanin formation and distribution. Since there are so many different genes, if we count all the possible alterations, many different color variants can be produced.
Answer:
A petroleum reservoir or oil and gas reservoir is a subsurface accumulation of hydrocarbons contained in porous or fractured rock formations. Such reservoirs form when kerogen (ancient plant matter) is created in surrounding rock by the presence of high heat and pressure in the Earth's crust.
Explanation:
Answer:
Photochemical Smog
Increased human population and decreased habitats for plants and animals
Explanation:
Photochemical smog is a type of air pollution, it is caused from the reaction of solar radiation with airborne pollutant mixtures of nitrogen oxides (NOx) and volatile organic compounds (hydrocarbons).
Smog is a byproduct of modern industrialization.

With an increase in human population there is a decrease in habitats because we continue to make more homes, stores, roads...etc.
The neurotransmitters that are partially responsible for the "high" that is associated with passionate love are chemically similar to the drugs, amphetamines.
- The neurotransmitters responsible for passionate love are dopamine, norepinephrine, and serotonin which show similar effects as shown by amphetamines.
- Amphetamines are drugs given to patients to help them deal with mental illnesses like insomnia and depression.
- Passionate love gives the same feelings as taking drugs such as amphetamines.
Thus, the neurotransmitters that are partially responsible for the "high" that is associated with passionate love are chemically similar to the drugs, amphetamines.
