The doubling period of a bacterial population is 10 minutes. At time \( t=80 \) minutes, the bacterial population was 50000 . What was the initial population at time \( t=0 \) ? Please enter a whole number Find the size of the baterial population after 3 hours. Please enter a whole number .

population d'une espèce animale dans une réserve. Cette population est estimée a 12000 individus en 2020. Les contraintes du milieu naturel font que la population ne peut pas dépasser les 60000 individus. Partie \( A \). Un premier modèle Dans une première approche, la biologiste estime que la population croit de \( 5 \% \) par an. L'évolution annuelle de la population est ainsi modé- lisée par une suite \( \left(v_{n}\right) \), où \( v_{n} \) représente le nombre d'individus, exprimé en millier, l'année ( \( 2020+n) \). On a donc \( v_{0}=12 \). 1. Déterminer la nature de la suite \( \left(v_{n}\right) \) et donner l'expression de \( v_{n} \) en fonction de \( n \). 2. Ce modèle répond-il aux contraintes du milieu naturel?

What was the indication to Richard Owen that the fossils he had found were not like other reptiles? A) They were found in climates where scientists know reptiles cannot survive. B) They had five vertebrae, and their limbs did not sprawl t the side, but were upright. Chey did not have any vertebrae, and their limbs sprawled out to the side rather than upright. (D) They were much smaller than any other bones that had ever been found.

Take Test: Frog-Amphioxus development Arrange the following statments showing the normal series of development 6. \( \hat{v} \) The neural crest cells separated 4. \( \hat{v} \) The neural tube separated from the dermal ectoderm 1. \( \hat{v} \) Ectodermal cells invaginate inwards 2. \( \leqslant \) Formation of neural folds 3. \( \approx \) The two neural folds attached toeach other at the midline 5. \( \% \) The neural tube formed.
