Answer:
In this question, consider how to correct two options:
The most successful is that a steroid hormone derived from components that contain cholesterol, this is because they are made up of lipids.
And the second correct option is that to be transported in blood fluids, THEY ARE GENERALLY (NOT ALWAYS) transported by transport proteins to their target organ, which may be close, far or even the same as the productions.
Explanation:
A variety of steroids and synthetic steroids have also been devised. Most are steroids, but some nonsteroidal molecules can interact with steroid receptors due to the similarity of their forms. Some synthetic steroids are weaker, and some much stronger, than natural steroids whose receptors they activate.
Answer:
John Dalton described the atoms based on there chemical and physical properties of which some were disproved later.
Explanation:
John Dalton described the atoms as
- Atoms are the smallest indivisible particles of matter.
- Atoms can neither be created nor destroyed.
- All atoms of the same element are identical by mass and size.
- Atoms of the different element have different mass and size.
- Atoms combined to form a compound and they do so in simply whole number ratio.
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
For a given substance, the amount of light absorbed depend on these four factors:
1. The wavelength of light.
2. The extinction coefficient of the absorbing material.
3. The path lenght of the medium through which the light is travelling and
4. The concentration of the substance.
