6. species Closely related of orchids never mate in the wild because they bloom at different times. This is an example of ______
Dimas [21]

Answer:

temporal reproductive isolation

Explanation:

The correct answer would be temporal reproductive isolation.

<u>Reproductive isolation</u> generally refers to series of biological mechanisms or processes that prevent members of different species from mating/fertilization or prevent the product of their mating to be invalid.

Some reproductive isolation processes prevent members of different species from mating or prevent fertilization as a result of mating. These processes are known as pre-zygotic reproductive isolation mechanisms.

Some other processes ensure that the product of fertilization (when it occurs) is invalid. These are known as post-zygotic isolation mechanisms.

<em>A good example of the pre-zygotic reproductive isolation process is </em><em>when closely related by different species bloom at different times</em><em>. This will prevent mating or cross-pollination to happen between the different species. This is known as temporal reproductive isolation.</em>

The pulmonary circulation conveys blood that is ______ in oxygen to the lungs before returning back to the ______ side of the he
Oduvanchick [21]

The pulmonary circulation conveys blood that is low in oxygen to the lungs before returning back to the left side of the heart.

<h3>The pulmonary circulation</h3>

The circulatory system is divided into two main parts namely:

  • pulmonary circulation and

  • systemic circulation.

The pulmonary circulation involves the movement of blood between the lungs and the heart.

Blood from the systemic circulation returns to the right side of the heart where it is pumped through the pulmonary artery into the lungs to be oxygenated.

After oxygenation has taken place in the lungs, the blood returns to the left side of the heart through the pulmonary veins.

Rus_ich [418]

The biotic factors that could influence are the organisms around these creatures. Furthermore, the independent variable in this study is the time of the day where observed are the average distance between these sea creatures and their output, the distribution of sea cucumbers as the dependent variable.

Hypothesis: There is a link between the time of the day and the distance of sea cucumbers amongst each other.
