Answer:
independent, dependent, control
Explanation:
The independent variable is the variable that you change. For example, if we were growing plants and wanted to see if more sun made them grow higher, you would change the amount of sun that each plant is exposed to.
The dependent variable is what you measure. This <em>depends</em> on the independent variable. So, in our plant experiment, the height of the plant is the dependent variable.
Control. The control is what stays the same. So in our plant experiment, the amount of water, type of plant, type of soil, and all of these things would stay the same to insure that the results are equal.
Intrasexual selection
Intrasexual Selection is when
members of the same sex within a species contend emulously with each other in
order to acquire chances to mate with others such as the male against male
competition for females. This type of selection often involves posturing and
fighting. Species or individuals suitable for intrasexual selection will possess
developed better weapons than their competitors.
The correct answer is C. Gardeners choose which plants they let reproduced based on the plant traits.
Explanation:
In general, selective breeding involves the intervention of humans in the reproduction of species, this includes mainly plant and animal species. Moreover, in selective breeding, humans choose which specific species or individuals reproduce to favor certain traits. For example, a farmer might allow only the biggest cows to reproduce because this will lead to bigger calves. In this context, the option that shows selective breeding is C because this shows the intervention of humans in reproduction by selecting the individuals that will reproduce.
Answer: Xylem is the specialised tissue of vascular plants that transports water and nutrients from the plant–soil interface to stems and leaves, and provides mechanical support and storage. The water‐conducting function of xylem is one of the major distinguishing features of vascular plants
