Answer:
Cold fronts form when a cooler air mass moves into an area of warmer air in the wake of a developing extratropical cyclone.
Explanation:
The warmer air interacts with the cooler air mass along the boundary, and usually produces precipitation. Cold fronts often follow a warm front or squall line.
Answer:
Echinoderms play numerous ecological roles. Sand dollars and sea cucumbers burrow into the sand, providing more oxygen at greater depths of the sea floor. This allows more organisms to live there.
Explanation:
They are also economically important to humans due to their use in scientific research and education and also for food.
Answer:
Negative feedback.
Explanation:
It is negative feedback because the reactions triggered by low glucose levels are trying to rebalance the glucose concentrations in our body to make it work properly.
In positive feedback, a product will only stimulate more the components that lead to that product to produce more of it, increasing the product's effect and an imbalance.

Answer:
According to the illustration of meiosis I, when sister chromatids stay together the phase to which it corresponds is telophase I (fourth option).
Explanation:
Meisois is a process of cell division whose final result is the obtention of two daughter cells with half of their genetic charge, with respect to the original cell. This process is divided into two parts, called meiosis I and II.
Telophase I corresponds to the phase of cell division in meiosis I, where the events that occur are the appearance of the nuclear membrane on the newly divided genetic material, cytokinesis -or cytoplasmic division- and above all due to the fact that each daughter cell already contains half of the genetic load, since the sister chromatids stay together.
