The article "Human Impact on the Galapagos Islands" and the video "Long Line Fishing Threatens Wildlife of the Galapagos Islands
andrew-mc [135]

Answer:

sea lions

sharks

sea birds

albatross

Explanation:

The article, "Human Impact on the Galapagos Islands" and the video "Long Line Fishing Threatens Wildlife of the Galapagos Islands", both mentioned that fishers catch animals in the water bodies that are not their main fishing targets. Some of these animals include sea lions, sharks, sea birds, and the albatross.

In the article, it was explained that overfishing was becoming a major problem  of the Galapagos Islands. Sea cucumbers and sharks were described as targets that are endangered and might soon become extinct.

In the video, sea lions, sharks, sea birds, and albatross were mentioned as targets of long line fishing which negatively affect the ecology of the Galapagos Island.

What are MAD (mitotic arrest deficient) proteins and when are they important in the cell cycle?
Mademuasel [1]

MAD (mitotic arrest deficient) are proteins related to spindle cell cycle checkpoint and it is important since they prevent the segregation of sister chromatids until all have bound to the spindle.

The cell cycle ensures the duplication of the genome and its distribution in daughter cells by passing through a coordinated and regulated sequence of events.

A series of checkpoints guarantee the orderly progression of the phases of cell division and the correct distribution of the duplicated genetic material in the daughter cells.

The checkpoints during mitosis are:

  • At the end of stage G1 and before S.

  • Before anaphase in mitosis.

  • DNA damage checkpoints in G1, S or G2.

The checkpoint before anaphase in mitosis guarantees the separation of chromosomes, and operates by activating the Mad2 protein that prevents the degradation of segurin, until the conditions are appropriate.

That is, the Mad2 protein prevents the segregation of sister chromatids until they have all bound to the spindle.

Therefore, we can conclude that MAD (mitotic arrest deficient) are proteins related to spindle cell cycle checkpoint and it is important since they prevent the segregation of sister chromatids until all have bound to the spindle.

Evaluate whether a sea beeze could occur night
Natalija [7]

Answer:

During the night the water releases it's heat much slower causing the air over the water to be warmer than the air over the land. This ends up working the same as the sea breeze only this time the lower pressure is over the sea and the air then moves from the land.
