Temperature is considered an biotic limiting factor. The correct answer is A.
Answer: The redirection of blood flow from one organ system to another is an outcome of coordinated vasomotion – constriction of precapillary sphincters and capillary blood vessels in tissues where blood flow is discouraged, and dilation in tissues where blood flow is promoted.
Explanation:
The correct answer is: The synaptonemal complex.
Non-sister chromatids are chromatids from two homologous chromosomes. In prophase I of meiosis two homologous chromosomes pair and this pairing is called synapsis. This allows possible crossing over to occur. Two non-sister chromatids are connected in synapsis by a protein-RNA complex called the synaptonemal complex.
Crossing-over or the physical exchange of chromosome parts might occur and bring to genetic recombination. The sites of crossing-over between nonsister chromatids and are called chiasmata.
What do mitochondria do? Where are they found?
They harvest chemical energy from food & carry out cellular respiration, the conversion glucose to ATP. They are found in cells of eukaryotes, except a few anaerobic protozoans. The ATP generating electron transport system is embedded in the inner membrane (cristae) and chemical reactions occur in compartments between membranes.
What are the functional categories of organelles?
Eukaryotic organelles comprise four functional categories: -manufacture (synthesis of macromolecules and transport within the cell), -breakdown (elimination and recycling of cellular materials - energy processing (conversion of energy from one form to another) -support, movement, and communication (maintenance of cell shape, anchorage, and movement of organelles, and relationships with extracellular environments) All four categories work together as an integrated team, producing the emergent properties at the cellular level.
So in smaller terms, I guess eukaryotic organelles do this.
