Answer and Explanation: The farmer has a pure-breeding line of tomato means the farmer has a tomato with genotype FFrrtt while the other line of tomato has genotype ffRRTT.
The cross between these lines gives a F1 generation of heterozygous full, red and axial or FfRrTt.
With an individual of F1 crosses with another individual of F1, the Punnet Square will be:
FfRrTt x FfRrTt
1) Dividing each characteristics, for simplicity:
F f
F FF Ff
f Ff ff
R r
R RR Rr
r Rr rr
T t
T TT Tt
t Tt tt
Analysing Punnett squares, we notice the line wanted (ffrrTT) will be produced, when an individual of F1 generation cross with another individual with the same generation.
A. into a climax community; species replaces another
B. and replaces another; ecosystem becomes stable
C. on unoccupied ground; biological community replaces another
D. and then fails; niche changes
E. intraspecific competition; experiences interspecific competition
Answer:
C. on unoccupied ground; biological community replaces another
Explanation:
Primary succession is a gradual change that occurs on bare rocks or areas that have no life existing on it before. It could take several years to be colonized by living things.
On the other hand, secondary succession are changes that occur when one biological community replaces another as a result of factors such as wild fires, or take place in abandoned farm land. New species of organisms take over the area that has life existing on it already. Secondary succession occurs on areas or land that has been colonized initially before.
Overall, minerals from animal products are better absorbed than those from plant because binders such as fiber are not present to hinder absorption.
<span>In getting her plants to grow, the gardener should use the color blue for her colored translucent sheets. The reason for this is because it will be absorbed by the plants, causing them to get the light absorption that they so desperately need. Other colors, such as green, are absorbed into plants (as can be observed by their green colors), and thus they do not absorb the light through this color.</span>
