Answer(Explanation):

Methanobrevibacter smithii is the predominant archaeon in the microbiota of the human gut. M. smithii has a coccobacillus shape. It plays an important role in the efficient digestion of polysaccharides by consuming the end products of bacterial fermentation.

Archaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebacteria kingdom), but this term has fallen out of use. Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota. Archaea are further divided into multiple recognized phyla.

Using a geometric growth model to predict population growth, a population of 10 individuals at time zero with a finite growth ra

Grace [21]

Answer: Option E, in 12 years.

Explanation:

A geometric growth model is characterized by its finite growth rate, known as lambda. The size of the population after a unit of time has passed can be calculated using the last known size and lamba as:

$N_{t+1} = \lambda * N_t$

Starting from the initial value of population, the next one will be calculated multiplying by 1.4, and the next one multiplying again by 1.4, thus we can define a function that relates the time passed in year to the size of the population:

$N(t) = \lambda^{t} *N_0$

Substituting our values we get the function that defines the growth of our poupulation:

$N(t) = 1.4^{t} *10$

Then, we just have to clear the t that gives a population of 500:

$500 = 1.4^t*10, divide\ both\ sides\ by\ 10\\50 = 1.4^t, apply\ log_{1.4}(x)\ to\ both\ sides\\log_{1.4}(50)=t\\11.63=t$

Thus, at 12 years, the population will be greater than 500.

Hello.................................................,.....what's a vaccine.thankyou

cestrela7 [59]

A vaccine is a medical material that mimics the pathogen, but in a harmless way. When our body's immune fights it off, it remembers how to fight the real pathogen when it enters our body. So, it protects us from diseases.

Which organelle do phagocytes use to digest engulfed particles?

cupoosta [38]

Answer:

Lysosome

Explanation:

Phagocytes use phagocytosis as a mechanism to eliminate large pathogens (mostly bacteria). They do this by expanding their plasma membrane around the pathogen. As a consequence, the pathogen is enveloped in a vesicle and incorporated inside the cell. Once inside, the lysosomes are incorporated, providing enzymes capable of destroying the microbe.
