Answer:
C. About 18 percent of the variation in blood pressure can be explained by a linear relationship between blood pressure and caffeine consumed.
Explanation:
Here, r = 0.428
∴ We can say it will give a positive curve, as 0.428 indicates it is a positive correlation.
Though the amount of correlation is low, still it is positive and more than 0.4
So, nearly about 18% of the variation in the blood pressure can be observed by the consumption of caffeine water. As consumption of caffeine water and blood pressure is both increasing so we can say that r= 0.428 will give a positive linear curve.
Answer:
The correct answer would be reproduction.
Single-celled organisms usually reproduce asexually with the help of cell division.
Asexual reproduction is a type of reproduction which takes place without the fusion of gametes and hence required only one parent.
Various types of asexual reproduction are fission (binary or multiple), budding, fragmentation, vegetative propagation etc.
Unicellular organism usually divide by fission either binary or multiple.
In binary fission, a parent cell divide into two equal sized daughter cells such as observed in bacteria.
In multiple fission, a parent cell divides into multiple daughter cells as observed in multiple fission of sporozoans etc. During this, parental nucleus divides several times with the help of mitosis without cytokinesis which produces several nuclei within a parent cell. The cytokinesis then takes place which results in separation and production of multiple daughter cells.
They reproduce over the years making it less frog to survive
