The population of bacteria in a culture grows at a rate proportional to the number of bacteria present at time t. after 3 hours it is observed that 500 bacteria are present. after 10 hours 4000 bacteria are present. what was the initial number of bacteria? (round your answer to the nearest integer.)

The initial number of bacteria is 371.

Explanation:

Let P represents population of the bacteria and t represents time,

According to the question,

Where, k is constant of proportionality,

Integrating both sides,

    ( Let )

If t = 0,

That is, is the intial population.

Since, when t = 3, P = 500 and when t = 10, P=4000

Hence, initial population is approximately 371.

i think it is dna, i'm not totally sure but i think it might be.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
