A root structure that protects buds from fire
helps short-leaf pines resist fires
Answer: Option D
<u>Explanation:</u>
Short leaf pine plant in the struggle for existence under hot scorching fire has developed a root structure that protects the buds from fire. This type of pine is called a fire resistant plant as it survives in the canopy of other trees.
Frequent burns have made them resistant to this fire. This is a wonderful example of how some plants survive in this extreme condition where it has to undergo frequent burns.They can also adopt and survive in drought conditions.
It is true that a<span>n ecologist who is studying the relationships among the dominant communities in a geographical region is studying a biome.
A biome is a group of ecosystems that have the same climate and similar dominant communities, so you can see that the answer to this question is T.</span>
Answer: No
Explanation:
Carbonic anhydrase (CA; carbonate hydro-lyase) is a zinc-containing enzyme that catalyzes the reversible hydration of carbon dioxide: CO2+ H2O<-->HCO3(-)+H+. The enzyme is the target for drugs, such as acetazolamide, methazolamide, and dichlorphenamide, for the treatment of glaucoma.
The zinc ion is located in a cone-shaped cavity and coordinated to three histidyl residues and a solvent molecule. Inhibitors bind at or near the metal center guided by a hydrogen-bonded system comprising Glu-106 and Thr-199. The catalytic mechanism of CA II has been studied in particular detail. It involves an attack of zinc-bound OH- on a CO2 molecule loosely bound in a hydrophobic pocket. The resulting zinc-coordinated HCO3- ion is displaced from the metal ion by H2O. The rate-limiting step is an intramolecular proton transfer from the zinc-bound water molecule to His-64, which serves as a proton shuttle between the metal center and buffer molecules in the reaction medium.
The two kinds of basic cell division include mitosis and meiosis.
Mitosis is where a parent cell divides and produces 2 genetically indentical daughters cells. So this means that when the cell division is complete, the number and even the sequence of chromosomes is exactly same as the original parent cell.
And in meiosis, also called reduction division, is where the parent cell divides and produces 4 genetically different daughter cells, which has only half of the number of chromosomes than that of the original parent cell. This process has to go through 2 times of divisions.
Mitosis is usually seen in most somatic cells, it is very important to activities such as growth, repair etc. Meanwhile, meiosis is seen in gametes, and its important for sexual reproduction.
FALSE, although there are many different senses they are the only way you can observe something.
