The liver

Answer:

The kidneys, although the liver is involved in hemoglobin breakdown. The liver is not an excretory organ, so it is the kidneys which break down red blood cells and produces urea, but that urea is not just from blood cells. In fact, hardly any of it is. Urea is largely composed of nitrogenous wastes given off by cells, and ammonia is NH3. Hope This Helps.

Below are the steps of the engineering process (not necessarily in order): 1) Know the background 2) Do the work 3) Make a plan
LuckyWell [14K]

Answer:

4 - 1 - 3 - 2 - 6 - 5

Explanation:

During an engineering process, first, we need to identify the problem, or the need because the process only will occur because of some need. Then, it's necessary to know as much as possible about the problem and the things that already exist or already were tested to solve it. Knowing the background will make the work easy.

After that, it's necessary to plan the things we'll do, knowing the costs, the time needed for activities, how many people will be necessary for each step, etc. It's really important to make a plan. Then, do the work, following the plan. Thus, the process must be tested. During the test of the results, some problems must be found, so it's time to evaluate and redesign the process, to solve these problems found.

How do you get hyphen notations?
laiz [17]

Answer:

In hyphen notation, the mass number is written after the name of the element. For example, in isotopic notation, the isotope of carbon that has a mass number of twelve would be represented as 12C . In hyphen notation, it would be written as carbon-12.

What does a mole of iron weigh
r-ruslan [8.4K]

As the atomic mass of iron is 55.847u

We say that it is the mass of one mole of iron.

By formula it can be find by

No.of mole=mass in g/molar mass

Mass in gram = no.of mole x molar mass

No.of mole =1

Molar mass = 55.847g

Mass in gram = 1x55.847

= 55.847g of Fe

Consider the work of Thomson, Rutherford, and Bohr. In your opinion, which was the most important and why? Be sure to state what
kobusy [5.1K]
The two of them both made models of the current atom, which was very excellent because now we could imagine how an atom would look.  I would say that the best one was the electron orbital configuration because we needed to know what valence electrons are.
