Spongy tissues composed of microscopic cells in which inhaled air is exchanged for carbon dioxide during one breathing cycle

2 answers:

7 0

<span>The answer is lungs. The lungs feel spongy due to the numerous (millions) of alveoli structures that compose it. It is in the alveoli that gaseous exchange between the lungs and the blood capillaries occurs. Alveoli are thin sac-like structures with numerous blood capillaries that provide large surface areas for gaseous exchange to occur efficiently</span>

Spongy tissues composed of microscopic cells in which inhaled air exchanged for carbon dioxide during one breathing cycle are lungs.
Gaseous exchange is the delivery of oxygen from the lungs to the blood stream, and the elimination of carbon dioxide from the bloodstream to the lungs. It takes place in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Delicious77 [7]

Answer:

e. secretion, absorption and chemical protection

Explanation:

Epithelial tissues is responsible for the protection of the skin, absorption of nutrients during digestion and secretion of waste materials. These tissues form covering to all body surfaces. They also perform a variety of other functions such as excretion of waste substances, filtration of air from dirt and particles and clean the air that is inhaled, diffusion, and sensory reception.

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.
