A. it has uracil
We know the sequence is RNA because it contains uracil.
Answer:
TRUE
Explanation:
Chemical weathering usually refers to the process in which the water comprising various chemicals reacts on the rocks and disintegrates them. The chemical weathering process occurs both at and below the surface of the land. At various depths, the rocks are comprised of cracks and fractures, which are filled up with water comprising the chemicals. This water reaching these joints and fractures are percolated from the surface. These chemicals comprising water start reacting with the rocks and eventually expands the cracks and joints.
For example, in the region where there is abundant carbonate rocks, these chemical comprising water (such as acid water) when enters, it reacts with the rocks and dissolves them, and thereby give rise to the formation of caves and sinkholes.
Thus, the above-given statement is true.
answer: the parent can be a single organism
explanation:
it only takes one "parent" single celled organism to asexually reproduce through binary fission
it only takes one "parent" multi celled organism to asexually reproduce through fragmentation or budding
I think it would be D. Dominant
Answer: <u>Option 4; Oxygen gains electrons and hydrogen to form water.
</u>
Respiration is a process where glucose is used and energy is released stored in this molecule. Oxygen is used during respiration as well and it gains the electrons and hydrogen to form water. And, gain of electrons is an oxidation reaction. So answer is option 4.
Since, oxygen is consumed during respiration, option 1 is incorrect.
Loss of electrons is reduction, so option 2 is also incorrect.
Glucose is used in respiration, thus option 3 is incorrect.
