The average female Atlantic cod (Gadus morhua) produces two million eggs in a single spawning. How does this relate to natural s

Alex Ar [27]

This is a typical example of R selection life strategy. These species, including the Atlantic cod, produce a large number of offspring with a low chance of surviving to adulthood. This strategy is particularly successful in environments that are unstable. The main advantage of this strategy in changing environments is that the ''cost'' of making offspring is very low, so you the species can produce large numbers offspring, ensuring that at least some of them will survive into adulthood and continue the species.
Natural selection, in this case, favors the individuals that are able to adapt the fastest to the changing conditions.

ribs

lungs

bronchioles

alveoli

diffuses

leaves

exchange

Explanation:

Your diaphragm, and muscles between your ribs, make air move in and out of your lungs. It travels through the trachea, bronchi, and bronchioles to alveoli. In the alveoli, oxygen diffuses into the blood and carbon dioxide leaves. This is gas exchange.

Air enters the lungs and leaves it as a result of the relaxation and contraction of the diaphragm and the muscles between the ribs. When both the muscles and the diaphragm relax, air enters from the trachea and travels through the bronchi and the bronchioles to the alveoli, where the oxygen in the air diffuses into the blood and carbon dioxide diffuse in the opposite direction. The entire process is known as gas exchange.

Answer: The number of chromosomes in the wolf's body cells is 78 while the gametes has 39

Explanation:

Since each body cell under only mitosis to yield two daughter cells with equal number of chromosome as the parent cell (i.e diploid number, 2n) while sex cells undergo meiosis to yield four daughter cells with half the number of chromosomes as the parent cell (i.e haploid number, n); thus, the wolf's body cells has 78 chromosomes while the gametes has 39 chromosomes.
