3. They eat sea urchins and other invertebrates that graze on giant kelp. Without sea otters, these grazing animals can destroy kelp forests and consequently the wide diversity of animals that depend upon kelp habitat for survival.
4. sea otters are critical to maintaining the balance of nearshore ecosystems, such as kelp forests, embayments and estuaries. Without sea otters, sea urchins can overpopulate the sea floor and devour the kelp forests that provide cover and food for many other marine animals.
5. haven’t found anything on that
Answer:
Threats to southern sea otters includes: 1.entrapment or entanglement in fishing gear, 2.oil spills, and climate change
Yeah something has been proposed to save the species which are:
1.Reduce, reuse, and recycle whenever you can.
2.Dispose of hazardous wastes properly.
3.Use nontoxic household cleaning products.
4.Don't litter or dump materials into storm drains
5.Purchase sustainable, recycled, biodegradable goods.
6. Range expansion is key to southern sea otter recovery and to the restoration of ecosystems in which sea otters were once the keystone species.
Southern sea otters play a critical role as a keystone species.
Without sea otters, sea urchins can overpopulate the sea floor and devour the kelp forests that provide cover and food for many other marine animals. Sea otters help ecosystems capture carbon from the atmosphere and store it as biomass and deep-sea detritus, preventing it from being converted back to carbon dioxide and contributing to climate change.

Answer:
5.23 moles
Explanation:
How many moles of iron are present in 3.15 × 10^24 atoms of iron?
1 mole has 6.02 X 10^23 particles
so
3.15X10^ 24 atoms =( 3.15 X 10^24)/(6.02 X 10^23) =(3.15/6.02 )X 10 =

1. What is the specific heat of a substance that requires 270 J of energy to raise the temperature of 4.2 grams by 25°C?
Heat required is mcΔT=100×0.39×50=1950 J
Solve any question of Thermodynamics with:-
The specific heat of the substance that requires 270 J of energy to raise the temperature is 2.57 J/g⁰C.
Specific heat capacity of the substanceThe specific heat capacity of the substance is calculated as follows;
Q = mcΔФ
where;
c is the specific heat capacityc = Q/mΔФ
c = (270) / (4.2 x 25)
c = 2.57 J/g⁰C
Thus, the specific heat of the substance that requires 270 J of energy to raise the temperature is 2.57 J/g⁰C.

In an AP Chemistry laboratory, students were given two unlabeled beakers and told that one of the beakers contained 1.0g of solid CaCO3 and the other contained
1.0g of solid AgNO3. They were told to devise an experiment to identify which compound was which. A student did so by adding 50 mL of distilled water to each beaker. Describe the student's observations that allowed him to identify each compound.
When the student adds 50 mL of distilled water to each beaker, CaCO3 will not dissolve in water while AgNO3 will dissolve completely in water.
We have to recall that according to the solubility rules, the carbonates of group two elements are insoluble in water. The solubility rules offer a convenient way of predicting the solubility of a compound in water.
When the student adds 50 mL of distilled water to each beaker, CaCO3 will not dissolve in water while AgNO3 will dissolve completely in water. This is because, the carbonates of group two elements are insoluble in water.

How do the atoms aluminum and fluorine react to form the compound aluminum fluoride?
Answer:
Aluminum fluoride is an ionic compound. Meaning that the two elements form a ionic bond. In ionic bonding, atoms receive and donate electrons in order to become stable. In this case, aluminum donates its three outer electrons to three fluorine atoms. Aluminum forms a triple positive aluminium ion (Becomes a cation) and fluorine forms three single negative fluoride ions (Becomes a anion).

Answer:
A tall and narrow A tall and narrow
Explanation:
Answer:
A. Tall and Narrow
Explanation:
The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength. But high amplitude waves tend to be short spent and tall narrow linings.
how many electrons does hydrogen need in order to have a full shell of valence electrons?
Answer:
One
Explanation:
In a hydrogen atom, the first outer shell only consists of two valence electrons, because it would already have one, the atom only needs one more.
It requires two electrons to completely occupy its outer shell, it frequently forms a single covalent bond with another atom. Because of this configuration, hydrogen can gain access to two electrons and completely occupy its valence shell.
What is Hydrogen?Hydrogen adheres to the duet rule because it only requires two electrons to completely occupy its valence shell. It deviates from the octet rule. Hydrogen only needs to form one bond. Because of this, H is always a terminal atom and never a central atom. Hydrogen is a chemical element with the symbol H and the atomic number 1.Hydrogen is the lightest element. Under normal conditions, hydrogen is a gas of diatomic molecules with the formula H2. It is colorless, odourless, tasteless, non-toxic, and extremely flammable. Hydrogen is a more environmentally friendly alternative to methane, also known as natural gas. It is the most abundant chemical element, accounting for 75% of the universe's mass. Water, plants, animals, and, of course, humans contain massive amounts of hydrogen atoms.To learn more about valence electron refer to:

when does cells breakdown a sugar molecule completely to produce chemical energy ATP the cells need to the following materials
Answer:
sugar and carbon dioxide
Explanation:
Chemical energy is stored in the bonds of sugars. When the bonds of a sugar molecule are broken, a burst of energy is released that the cell can use. Cells can release energy in two basic processes: cellular respiration and fermentation. Cellular respiration requires oxygen, but fermenta- tion does not.
