The answer is B.
It warms and filters the air as it enters the sinus, it also retains moisture because cold dry air could irritate the lungs.

Answer:

The correct answer would be "Warm and clean the air before it moves to the lungs."

The external opening of the respiratory system is formed by the nose and nasal passage.

The nasal cavity is lined with mucus and hairs.

The main functions of the nasal cavity moisturize, warm, and filter the air as it passes from nose to the lungs.

What is the magnitude of the force exerted by the biceps fbiceps? What is the magnitude of the force exerted by the elbow felbow

Slav-nsk [51]

Answer:

The magnitude of the force exerted by the biceps $f_b_i_c_e_p_s$ is 218.38N

The magnitude of the force exerted by the elbow $f_e_l_b_o_w$ is 194.37N

Explanation:

Firstly , lets calculate the magnitude of force exerted by biceps $f_b_i_c_e_p_s$ -

Mass of the forearm=

$m_f=1.50kg$

Mass of the ball =

$m_b_a_l_l=950g$

= 0.950kg

so, weight of the forearm=

$w_f=m_f$ g

weight of the ball=

$w_b_a_l_l=m_b_a_l_l$ g

Now , balancing torque about the elbow , we have-

$F_b_i_c_e_p_s\times d_b_i_c_e_p_s= w_f\times\frac{d_b_a_l_l}{2} + w_b_a_l_l\times d_b_a_l_l$

(here , distance of the bicep is 2.50cm = 0.025m and distance of the ball is 36cm= 0.36m)

Now putting the given values in the formula -

$F_b_i_c_e_p_s\times 0.025= 0.95\times9.8\times\frac{0.36}{2} +1.50\times 0.36$

$F_b_i_c_e_p_s=218.38N$

Now, lets calculate the force exerted by elbow $F_e_l_b_o_w$ -

Balancing the vertical forces

$F_b_i_c_e_p_s=F_e_l_b_o_w+w_f+w_b_a_l_l$

$F_e_l_b_o_w = 218.38-(1.00\times9.8)-(0.95\times9.8)$

$F_e_l_b_o_w=194.37N$

Animals in the food chain need to eat less food than the animal in the previous level did to stay alive. True or False?

Volgvan

I would say true because for them life will not go on and the animal that is eating another animal there will not be no more of them and they will all die off

______ results in genetically identical daughter cells, whereas ______ results in genetically different daughter cells.

notka56 [123]

Identical daughter cells are produced as a result of mitosis whereas meiosis results in the formation of the daughter cells which are different genetically.

Mitosis and Meiosis are the stages of the cell cycle which can be further divided into stages called prophase, metaphase, anaphase and telophase. Mitosis results in the formation of two diploid daughter cells which genetically identical to the initial parent cell.
In the process of meiosis, the DNA gets exchanged between the chromosomes that are paired. This shuffling of DNA results in the formation of daughter cells after cell division which are genetically dissimilar.
