1 answer:

3 0

The best answer is D because construction would be bad for the environment and take up space on the soil that is trying to be preserved. Also, for C, planting only one crop type in soil is not very beneficial to the soil at all. IT is best to plant multiple crops in the soil and move the crops to different parts of the soil each year when planting them.

In a lab about the activity series, a solution of copper(II)chloride is placed in a test tube with zinc metal. If zinc is higher

Tcecarenko [31]

Answer:

Option D, Zinc is higher on the activity series because there is clear evidence of a reaction.

Explanation:

It is very clear that a metal which is higher in activity will replace a metal having lower activity.

Since, Zinc has higher activity than copper, it is very sure that it in a copper chloride solution it will replace copper and produce zinc chloride solution leaving behind copper as residue.

Residues of copper is a clear evidence of reaction

The chemical equation for this reaction would be -

$CuCl_2 + 2Zn^+ -----> 2ZnCl + Cu^{2+}$

Hence, option D is correct

Which part of the hemoglobin molecule binds carbon dioxide for transport?

Kipish [7]

Answer:

α-amino group

Explanation:

The α-amino group on the hemoglobin binds with the CO2 and this action causes a conformational change in the structure of hemoglobin that ultimately causes the release of linked oxygen. When CO2 is binded to the hemoglobin the whole complex is termed as carbamino-hemoglobin.
