Answer:
Tubules?
Explanation
The trachea, spiracle, and air sac are part of their respiratory system, Howeber, the tubules are what take away the carbon dioxide from their system. Im not sure if they produce the carbon dioixde. But they are a part of what removes the carbon-dioxide from their body.
1.) B it is not d because it shows a growth in the beak size, it didn't say anything about the birds having larger beaks just that the size increased
2.) A
p=.5 q=.5
q^2=.25 p^2= .25 2(pq)= .5 everything added up is 1.0 so we good
so q^2, which is the recessive gene or gg, is 25 percent
Answer:
Any factor in the environment that does not depend on the number of members in a population.
Explanation:
Density independent limiting factors also cause population sizes to increase. For example, the water from a flash flood increases the growth of vegetation, thereby providing more food for primary consumers in the ecosystem.
It's basically a wave that moves back and forth at regular speed through matter. because of that it transfers energy through a medium (matter). however the movement of the wave is limited because of this but it can still move over long distances. so because of this these types of waves don't move far from their original point or Equilibrium position. in short think of throwing a pebble into water and seeing the little ripples from it, that's a mechanical wave.
Answer:
Genes lying close to each other on chromosome
Explanation:
When genes lie close to each other on chromosome, they are inherited together as an intact unit in meiosis cell division and such genes are termed as linked genes.During meiosis the genetic material (allele/genes) is exchanged between the homologous parent chromosome which causes chromosome recombination and thus the formation of linkages These genes have high chances of recombination as they lie close to each other.
