What climate condition occurs during El Niño?
SpyIntel [72]

During an El Niño, the trade winds weaken in the central and western Pacific. Surface water temperatures off South America warm up, because there is less upwelling of the cold water from below to cool the surface. The clouds and rainstorms associated with warm ocean waters also shift toward the east.

Tanzania [10]

Answer:

1. False

2. True

3. True

4. False

Explanation:

In mammals, the contraction of the heart muscle is caused by pacemaker cells localized within the sinoatrial (SA) node. These cells rhythmically generate slow electrically-induced action potentials due to their slow rate of depolarization. The pacemaker cells generate the action potentials that propagate through the heart and trigger the contraction of myocyte cells (i.e., myocytes simply conduct the action potential waves). The slow depolarization of pacemaker cells occurs during diastole, i.e., during the period of relaxation of the heart muscle.

tumor cells: tumor cells

Researchers from Harvard Medical School, Boston, and the Institute for Systems Biology, Seattle, have discovered that the remains of tumor cells killed by chemotherapy or other cancer treatments can actually stimulate tumor growth by inducing an inflammatory reaction. The study also reveals that a family of molecules called resolvins can suppress this unwanted inflammatory response, suggesting new ways to enhance the effectiveness of existing cancer therapies

Conventional, radiation- and drug-based cancer therapies aim to kill as many tumor cells as possible, but the debris left behind by dead and dying cancer cells can stimulate the production of proinflammatory cytokines, signaling molecules that are known to promote tumor growth.

“Dead and dying tumor cells are an underappreciated component of the tumor microenvironment that may promote tumor progression,” explained Charles N. Serhan, PhD, Director of the Center for Experimental Therapeutics and Reperfusion Injury at Brigham and Women's Hospital and Professor at Harvard Medical School. Serhan and colleagues therefore decided to investigate whether tumor cell debris can stimulate tumor growth.

The passage states that organisms that live in fresh water cannot survive in salt water. These organisms will undergo a process
eduard

D) egg in Kayro syrup

Explanation:

An egg in Kayro syrup will experience plasmolysis. During the process of plasmolysis a body loses water to another one at a higher concentration. Fresh water organisms suffers plasmolysis because in salt water, the concentration of dissolved salt in the water is high and this makes the water hypertonic to their body.

  • In a hypertonic solution, the egg will lose water and begins to shrink in the Kayro syrup.
  • The Kayro syrup is hypertonic to the egg and by so doing, it will lose water to it.
