DNA can be made into mRNA
Answer:
Layers of the atmosphere. The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth's surface is called the exosphere.
Explanation:
Answer: C). A biozone can help trace the path of evolution over time.
Biozone is a stratigraphic unit which contains fossils in layers of strata existed in a particular geologic period. It is named as biozone because it depicts the number of biological taxa existed in particular strata. Therefore, the variation in features within taxonomic groups in biozones can give indication of evolution with respect to time.
Answer: Number 2, aka Solid wastes on land.
Explanation: Bacteria in soil is a natural thing, so it's not polluting the earth. Oxygen in the atmosphere is letting us live, meaning it's not polluting the earth. Fish in rivers is also another natural thing, leaving us with solid wastes on land.
Answer:
Net membrane potential is equal to the difference of positive charge and negative charge existing at the inner and outer side of the cell respectively. Since outer negative charge is higher in concentration, the net membrane potential is negative
Explanation:
The cell membrane potential defined as the net difference of ion concentration existing at the inner and outer side of a cell membrane at nay instance.
When the cell is at the resting potential, the positive potassium ion starts accumulating at the inner surface of the cell membrane as it becomes favors positive potassium ion. This leads to development of negative potential at the outer side of cell membrane by the accumulation of negative ions or charges. Hence, a net negative potential membrane develops.
