Answer:
<em>The pulmonary artery channels oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium. The aorta channels oxygen-rich blood to the body from the left ventricle.</em>
Hope this helps!!
Increases because there's more food for the carnivores, as a result, the gradually the herbivores will decrease as the reach to a point they are no longer able to feed all the predators
Answer:
a Anaphase I
b Metaphase I
c Telophase I
d Anaphase II
e Prophase I
f Telophase II
Explanation:
Prophase I begins after the DNA has been duplicated, as shown in picture e. The chromosomes are condensed, and also visible, which is apparent in picture e.
The next stage is called Metaphase I, in which the pairs of homologous chromosomes align at The the centre of the cell and the spindle fibres attach, as shown in picture b.
The pairs of chromosomes are pulled apart to opposite poles of the cell by the spindle fibres., as shown in picture a. This stage is called Anaphase I.
Then, a process called Telophase I occurs, when the cell divides into two daughter cells. One of these cells is shown in picture c.
Picture d shows the stage Anaphase II, where the spindle has attached and the chromatids are pulled to the opposite poles of the cell.
The final picture left is picture f, which shows the daughter cell at the end of meiosis II, where the nuclear envelope is reforming, as in telophase II.
They are examples of precipitation
Alternation of generations is the fluctuation of the diploid and haploid stages in plants. The diploid stage occurs through mitosis while the haploid stage works through meisos and asexual reproduction. In vascular plants, the diploid stage produces seeds. In non-vascular plants, the haploid stage produces the spores.
