Coral Bleaching is hazardous to fish because It leaves fish and corals vulnerable to deseases.And the average temperature of tropical oceans increases by 0.1 degrees C, over the past century.Fish are affected because, most fish in the ocean live in coral reffs, which end up dying, and leaving its habitant fish without a home.

Briefly explain what properties of the atoms in water (H2O) give water the ability to form hydrogen bonds. Your answer should in

Serggg [28]

Answer:

Water molecules are polar, so they outline hydrogen bonds. This gives water great properties, such as a for the most part high bubbling or boiling point, tall specific warm, cohesion, grasp, and thickness. Hydrogen has an electronegativity of 2.0, though oxygen has an electronegativity of 3.5. The refinement in electronegativities is 1.5, which infers that water can be a polar covalent molecule. In water, an electron from each of the hydrogen particles is drawn towards the oxygen particle. Protons, as unequivocally charged hydrogen particles, move outstandingly rapidly in water from one water molecule to the taking after, which is why the conductivity of water is modestly tall.

The mechanism whereby an enveloped virus leaves a host cell is called

Levart [38]

Answer:

Release or egress

Explanation:

Virus can reproduce only within a host cell, this cycle of infection begins with the attachment, where the virus attaches to a specific receptor site on the host cell, after this comes the entry, in the case of enveloped virus, the envelope can fuse directly with the cell membrane to enter the cell, they can also enter through endocytosis. After entering the cell the virus initiates a replication and assembly mechanism depending on its genome, finally, the last stage of viral replication is the release or egress of the new virions produced in the host organism, some viruses can be released when the host cell dies, but some can leave infected cells by budding through the membrane without directly killing the cell.

1. In the marine food web shown, which of the

Rudiy27

Answer:

C. Ringed seal

Explanation:

A marine food web illustrates how energy is passed from one organism (level) to another in this aquatic rich ecosystem.

In the following food web, the interaction goes like this:

The Arctic cod feeds on plankton and silverslides and it is preyed upon beluga whales and ringed seals.
The sea duck goes to the bottom of the ocean to feed on benthic organisms and also consumes plankton and silverslides. It doesn't really have predators.
The beluga whale doesn't really have predators, but it feeds on fish such as silverslades and Arctic cod.
Ringed seals feed on plankton and Arctic cod and are then consumed by polar bears.

Therefore, according to this information, all organisms except the ringed seal feed directly on silverslides.

the hawaiian islands were formed by volcanic activity, but they are far from any plate boundaries. explain how this could occur.

zhannawk [14.2K]

Answer:

Hotspots from under the ground

Explanation:

There are three different situations where an volcano can form. A divergent boundary, where two tectonic plates move away from each other, subduction boundary, where one of the tectonic plates moves under the other, and a hotspot. Scientists are not completely sure how hotspots form.

When human red blood cells are placed in pure water, the cells immediately burst. which process explains what happens to the red

irga5000 [103]

The process of osmosis explains what happened to the cells.

Osmosis is where water molecules will flow from a region of higher water potential to a region of lower water potential, through a partially permeable membrane. Red blood cell is a human cell and have a partially permeable membrane. At the same time, pure water has the highest water potential among all substances, and of course higher than the cytoplasm of the red blood cell, therefore, water molecules will flow from the water to the red blood cell.

So much water has flown to the red blood cells that the cell membrane cannot hold all and eventually the cell bursts. Therefore, the process of osmosis explains this result.
