PLEASE ANYONE I NEED HELP!!!!

what is the net ionic equation and what are the spectator ions of Bel2(aq) + PbSO4(aq) = BeSO4(aq) + Pbl2(s)

Answer:

The Moon circles the Earth once every 27.3 days – each sidereal month – but its phases repeat every 29.5 days – each synodic month. The difference arises because the Earth itself moves around the Sun by a distance of around thirty degrees each month.

Explanation

Answer:

Light reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where carbon fixation takes place. The light-independent reactions of the Calvin cycle can be organized into three basic stages: fixation, reduction, and regeneration.

Answer:

It uses ATP and NADPH and converts it into glucose and other carbohydrates; glucose and other carbohydrates

Answer:

the answer is a niche

Explanation:

Answer:

No.

Explanation:

No, the sunlight does not act as a limiting factor the same way it does in the ocean because the lake has lower depth as compared to ocean which is very deep i. e. more than 3000 meters where sunlight does not reach and we know that sunlight is very important for the survival of plants. Sunlight reach in the water about 1000 meters so plants can survive and do photosynthesis due to its low depth.

Acid rain will impact the crayfish population because acid rain decreases the pH of water and this lower pH causes death of the crayfish and also the food of crayfish and thus lower the population of crayfish due to unavailability of food..

Answer:

Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.

is correct!

Answer:

Any living creature that lives beneath the Pacific surface will absorb the sunlight for nourishment. If the sun banishes all the living organisms (plants and algae) will suffer due to the lack of photosynthesis. The sun has a massive effect on the aquatic life in the oceans, lakes, or any body of water; including the Pacific Ocean.

Explanation:

Answer:

this feels like philosophy not biology lol.

Explanation:

It is the moment when a mind latches onto an idea or purpose that an individual finds meaning in their life. This means that it doesn't matter who or where you are or whatever activity you might be doing – if your mind believes it has discovered the meaning of life, then that is the meaning of life for you

Answer:

1.  Never judge someone by appearance, particularly color or outfit/tattoos

2. Always treat someone with respect as if they are your friend

3. Never presume someone's financial conditions based off of their lifestyle

With these rules, we could theoretically be one step closer to equality.

Answer:

Explanation:

Oxygen gas and water must be present for iron to rust.

A region of the metal’s surface serves as the anode, where oxidation

occurs:

Fe(s) → Fe²⁺ (aq) + 2 e⁻

The electrons given up by iron reduce atmospheric oxygen to water at the cathode, which is another region of the same metal’s surface:

O₂ (g) + 4H⁺ (aq) + 4 e⁻ → 2 H₂O (l)

The overall redox reaction is:

2 Fe(s) + O₂(g) → 4H⁺(aq) + 2Fe²⁺ (aq) + 2 H₂O(l)

The Fe²⁺ ions formed at the anode are further oxidized by oxygen:

4 Fe²⁺ (aq) + O₂(g) 1 (4 + 2x) H₂O (l) → 2 Fe₂O₃ . xH₂O(s) + 8 H⁺(aq)

This hydrated form of iron(III) oxide is known as rust. The amount of water associated with the iron oxide varies, so we represent the formula as 2 Fe₂O₃ . xH₂O.

Osmosis is a special kind of diffusion that only involves water moving through a selectively permeable membrane.

Answer:

Albert Einstein is a German-born physicist and scientist who has created many ideas and theories relating to the study of relative. He is famously known for creating the famous equation [tex]e = mc^{2}[/tex] (Energy equals mass times the speed of light squared).

He was involved in the help of creating nuclear powered- mechanisms (not for destroying things, but for helpful, everyday things). Matter has an inherent amount of energy to it, mass can be converted (under the right conditions) to pure energy, and energy can be used to create massive objects that did not exist previously. Nuclear fission takes place when a heavy atomic nucleus, such as uranium, breaks into two or more smaller pieces with the release of some energy. During this process some of the mass of the original atom is converted into energy in accordance with the equation [tex]e = mc^{2}[/tex].

Answer:

Diffusion. Molecules are in constant motion and tend to move from regions where they are in higher concentration to regions where they are less concentrated. ... An example of diffusion in gases occurs when a bottle of perfume is opened at the front of a room.

Answer:

Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects. ... All photosynthetic organisms have chlorophyll a which absorbs violet-blue and reddish orange-red wavelengths. Chlorophyll a reflects green and yellow-green wavelengths. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.
