Answer:
Li
Explanation:
- In this case, "least exothermic" means that the correct answer is the least reactive of the alkali metals.
- The lower the ionization energy is, the higher the reactivity of the alkali metal is.
With the above information in mind, and remembering that ionization energy tends to decrease as we go down the group in the periodic table, the correct answer is Li, as it has the highest ionization energy among the alkali metals.
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:
Great question!The color of grass leaves (usually green) is mostly due to the absorbance of the other wavelengths of visible light by chlorophyll. Therefore, any differences in gene expression (that ultimately determine phenotype) that affect the concentration of chlorophyll in the leaf will, in turn, affect the color of that leaf. My guess is that, in the absence of light, you could still measure chlorophyll concentration, and assume what the color would be. However, you need transmitted (reflected) light in order to perceive color. I don't know, if a tree falls in the forest, and none is around to hear it, does it make a sound? Hope this helps. Keep the questions coming!
