Answer:
A. Accurate but not precise
Step-by-step explanation:
The illustration given shows that the was far from each other which means it is not precise because precision is that the given data must be close to each other. However, it is accurate because the darts are closer to the bullseye which can still be considered as accurate. Therefore, I believe this is accurate but not precise.
The steroid hormone is secreted by three glands- adrenal cortex, ovaries, testes.it is derived from cholesterol
Answer:
chromosomes
Explanation:
DNA of organisms is organized into one or more thread-like structures called chromosomes. Chromosomes are made of DNA and its packing proteins. During cell division, the thin mass of chromatin which in turn is made of DNA and its packing protein condense and becomes visible as individual chromosomes. The DNA molecule is wrapped around histone proteins to form nucleosomes which in turn become compact into chromatin fibers.
The further condensation of looped domains formed by the coiling of chromatin fiber forms chromosomes. The part of a chromosome that holds its two arms together is called centromere. Chromosome becomes visible during the prophase stage only when condensation of chromatin takes place.
Answer:
No, se debe a la capacidad de evolucion genetica que tengan los seres vivos frente a los cambios amientales.
Explanation:
Algunos animales frente a cambios ambientales buscan desarrollar mutaciones geneticas que le confieran una cualidad fenotipica que los beneficie en ese medio, es decir como por ejemplo: picos mas largos, plumajes de diferentes cualidades, patas o dedos mas cortos, etc.
Si esta modificacion genetica es capaz de transmitirse a travez de los progenitores de la especie entonces se puede deducir que la especie evoluciono, por ende tiene una adaptacion exitosa y no depende de sus celulas sino del codigo genetico que estas contengan y si son capaces de transmitir dichos genes para poder asi heredar otras generaciones las cualidades fenotipicas ideales.
