What is the function of the conjugation pilus?

Answers

Answer 1

Answer:

Answer:

It is involved in the process of conjugation-exchange of genetic material between two bacteria

Explanation:

Conjugation is one of the ways by which bacteria exchange their genetic material (horizontal gene transfer). Two bacterial cells must physically connect in order to perform the conjugation. The linking occurs through a pilus.

Pilus is an appendage on the surface of bacteria cell and it is also called fimbria. Pilus is filamentous, tubular and composed of oligomeric proteins-pilin.

Donor cell contain pilus that will attach to the recipient bacterial cell and induce the transfer.

Like logistic growth, exponential growth A. reaches its carrying capacity over time. B. can be plotted in the shape of an S curve. C. exhibits a period of rapid growth as the population size increases. D. is slowed by limiting factors.

Answers

The answer is C. exhibits a period of rapid growth as the population size increases.
Logistic growth and exponential growth are types of population growth. Both types exhibit a period of rapid growth as the population size increases. But, there are some differences between these two types. Population with logistic growth reaches its carrying capacity over time, but exponential growth do not. Logistic growth can be plotted in the shape of an S-curve, and exponential growth can be plotted in the shape of an J curve. Also, logistic growth is slowed by limiting factors. When there are no limiting factors, population exhibits exponential growth.

what percentage of the energy flowing through primary producers is ultimately transferred to secondary consumers?

Answers

Energy transfer is the transmission of food energy from organism to the next which is illustrated as the food chain. Normally and typically, the autotrophs are the photosynthetic organisms that primary makes food for itself and for other organisms. Hypothetically, we can assume that about 6000 kilocalories per square meter per year these autotrophs can collect and store energy. Primary consumers like omnivores such as deer, cow, birds and etc. receive almost 10% as much from these autotrophs. Secondary consumers receive for as much as 1% of the total energy that was from the autotrophs.
