This is the job of the excretory system. You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body. Recall that carbon dioxide travels through the blood and is transferred to the lungs where it is exhaled.

Answers
Answer:pu-239
Explanation:
Pu-239 is regarded as the radioisotope requires long-term storage as the method of disposal, to protect living things from radiation exposure over time
Disposal of radioactive nuclear waste is often regarded as a problem.
The waste sources are:
Nuclear power reactors Bomb-related nuclear materialDisposal of bomb-grade plutonium is often difficult.
The longer lived isotopes are:
Plutonium-239 whose t1/2 is 24,110 years, Plutonium-240 whose t1/2 is 6,540 years, Curium-245 whose t1/2 is 8,500 years. etc.The storage of the longer lived elements is through containment for the next several thousand of years.
The control or management of radioactive waste is a hard, multifaceted procedure.

The dark moths were better hidden from predators and therefore more of them survived and this allowed them to have offspring.
Answer:
The dark moths were better hidden from predators and therefore more of them survived and this allowed them to have offspring.
Explanation:
If all of the light colored trees disappeared and there are only dark colored ones, then that means that the light colored moths wouldn't be able to live long since their traits wouldn't match the environment. This then leads to the conclusion that dark moths would be better hidden since their trait fits their current environment and would let them be hid much better from predators. This would allow them to survive longer and eventually, reproduce.

How many valence electrons are there in Se atom?
Answers
Answer:
4 valence electrons
Despite the fact that the word silicon has a ubiquitous affiliation with all things electronic, Si itself is not a good electrical conductor. It has 4 valence electrons, meaning that filling its outer shell it can form a very strong lattice with 4 neighboring Si atoms-with no un-bonded electrons remaining
Answer:
The numer of valence electrons is defined as the number of electrons present in the outer most shell of the atom.So, in the case if selenium, there are 6.
Give an example of a decomposer, and explain what would happen if decomposers were absent from a forest ecosystem. Provide evidence to support your claim and explain your reasoning
Answers
Answer: Bacteria, some insects, and fungal species are the decomposers of the dead and decaying matter.
Explanation:
The decomposers are the organisms which act and feed on the dead and decaying organic matter so as to obtain energy from it and degrade it to the simple forms that can be utilized by the plants. Bacteria, some insects and fungi that live in the soil and on the decaying matter. The fungi for example decay on the lignin present in the wood so helps in wood decomposition of trees. If the decomposer like fungi are absent the wood mass will not decompose and it will remain as waste and can be used by the plants in the form of nutrients.

A hydrochloric acid solution contains 36 percent HCl by mass. Calculate its
molality
Answers
M=moles of solution / kilograms of solvent
Mass %= (mass solute/mass solution)x100%
Assume 100g of solution
Find moles of solute
Mass solute = (mass %/100%)mass solution
=(36%/100)100g=36 gHCL
36 gHCL 1 mol HCL/36.458 gHCL= 0.987molHCL
36% HCL by mass 100 g solution
36g HCL 0.987Mol HCL
Molarity=moles solute/kg solvent
Find kg solvent
Mass solution = mass solute + mass solvent
Mass solvent = mass solution - mass solute
= 100 g-36=64 g solvent
64 g solvent = 1 kg solvent/1000 g solvent = 0,064 kg solute
Molarity= molHCL/0.064 kg solvent
=0.987/0.064
=15.42 mHCL

What is the mass of 3.25 moles of sodium hydroxide (NaOH)?
Answers
Answer:
1 mole is equal to 1 moles NaOH, or 39.99711 grams.
Explanation:
Hope this helps have a nice day :)
The statement of the mass of sodium hydroxide (NaOH) is "130 g."
What is mass?A substance is something to do with mass that takes up space. The mass of a compound is the total amount of atoms present in grams that make up a molecule. The grams is the unit of mass.
In order to determine the mass in grams, multiply moles of the substance value by its molar mass to convert moles into grams.
Mole to gram conversion factor,
[tex]=\;given \;mole\;.\;\frac{grams}{1\;mol}[/tex]
Mass of NaOH comes out to be,
[tex]=\;3.25\;mol\;.\;\frac{39.997\;g}{1\;mol}[/tex]
= 129.99 g
= 130 g
Hence the correct answer is 130 g.

The number of grams of sulfur in 223 grams of sodium sulfate is . . . Grams And explain how, I still dont get it fully
Answers
Answer:
50.25 g of sulphur, S.
Explanation:
Mass of Na₂SO₄ = 223 g
Mass of sulphur =?
Next we shall determine the molar mass of Na₂SO₄. This can be obtained as follow:
Molar mass of Na₂SO₄ = (23×2) + 32 + (16×4)
= 46 + 32 +64
= 142 g/mol
Mass of S in 142 g of Na₂SO₄ = 32 g
Finally, we shall determine the mass of S in 223 g of Na₂SO₄. This can be obtained as follow:
142 g of Na₂SO₄ contains 32 g of S.
Therefore, 223 g of Na₂SO₄ will contain = (223 × 32) / 142 = 50.25 g of S.
Thus, 223 g of sodium sulfate, Na₂SO₄ contains 50.25 g of sulphur, S.
