Answer:
Explanation:
A virus is a nucleoprotein and the genetic material is infectious. Speaking in strictly general terms, viruses infecting plants have single-stranded RNA. On the other hand, viruses that infect animals have either single or double-stranded RNA or they might have double-stranded DNA.
D, would be the correct answer because it would help you be more active than to be stiff.
Answer:
The correct answer is - hypotonic solution.
Explanation:
A hypotonic solution is a solution with low osmotic pressure than another or adjacent solution. In biology hypotonic solution that has low solute concentration and more solven or water than the another solution.
In such solution the solute has less or decreased solute and the movement of the water will be inwards the cell which cause cell swelling and breakage or burst. In the given question the mistake in preparing culture media creating hypotonic as it swells and burst.
Thus, the correct answer is - hypotonic solution.
Answer:
C Differences among temperature, air pressure, and density
Explanation:
Classification of the atmosphere layer will be different based on the temperature, air pressure, and density. Generally, air pressure and density will go less at the higher layer, but the temperature varies greatly. Altitude and latitude define a location on earth, not the layer of atmosphere. Most weather just happens at the troposphere layer. The distance from ground level can be used as a rough estimate but not as precise criteria.
Answer:
The image illustrates the human-induced environmental change related to <em>wildlife hazard
</em><em>.</em>
Explanation:
Options for this question are:
- <em>Pollution
.</em>
- <em>Wildlife hazard
</em><em>.</em>
- <em>Eutrophication
.</em>
- <em>Non-sustainable harvesting.</em>
Human-induced changes in the environment are all those actions that are consciously carried out and that affect the normal development of natural life or ecosystems. Many of these changes are negative and put wildlife at risk.
In the image you can see a bear on a stretch of road, probably built near of its natural habitat. Constructions in natural areas clearly affect nature and the wildlife present there, representing a danger to the wild species present there and even to humans.
