Answer:
The correct answer will be option-Selective survival and reproduction is a requirement of evolution by natural selection.
Explanation:
Evolution is a slow process of change in the heritable features of species over a successive generation of time.
The process of evolution takes place during a long period of time only when the advantageous mutations are passed on to the generations and become established.
The mechanism of this process is natural selection which increases the reproductive rate as well as the survival rate of the species.
Thus, the selected option is the correct answer.
Answer:
The paramecium body.
Explanation:
1. The objective lenses on a compound light microscope doess have powers that start of as smallest to highest power, 4x, 10x, and 40x on the maximum power setting. This means that the sample can be magnified either, 40x, 100x or 400x.
At 40x magnification Stella will see organism 5mm.
At 100x magnification Stella will be able to see organism 2mm.
At 400x magnification Stella will be able to see organism more closely, 0.45mm, or 450 microns.
2. Paramecia are shoe shape or molded and almost transparent and shrouded in a defensive pellicle.
Pellicle capacities like skin and shields them from the components. For movement they have cilia.
The main benefits of the monoculture farming are that it has higher production, is more efficient, and has lower costs. All three advantages of the monoculture farming are making it much more attractive for the farmers as it is more profitable and easier for work.
In this type of farming there's no spaces of the arable land that are lost because it is all planted with the same culture, and there isn't any other cultures with which there should be made empty spaces in between.
The costs for farming are lower, and also the work is easier and more efficient because the machinery can be used in the same manner constantly and the work can go on systematically on the farmlands.
On the other hand, we have to mention that there are also negative effects of this type of farming like the total destruction of animal and plant biodiversity in the area where it is practiced, as well as making the entire crop vulnerable to diseases and environmental changes.
Answer:
This happened because the check points in cell cycles are not working properly which can help to stop cells having abnormal chromosomes.
See the attachment for proper understanding what actually happened in cell cycle check points.
Answer:
b
Explanation:
To denature a protein is to alter its three dimensional structure. Loss of protein structure consistently correlates with loss of protein function, so it is a strong correlation.
