Answer:
Plants stem grow against the gravity while roots grow towards the gravity and this prices is known as the geotropism or gravitism explains that the roots grow toward the direction of the gravity pull termed as positive geotropism.
Auxin is a hormone that acts at the bottom of the cell and have different function in roots and stems as in stems it promotes the elongation of the cell against gravity while in roots it is promotes the elongation of the cell towards the gravity.
Answer:
The frequencies would be - AaBb= 2/4= 1/2.... Therefore AaBb= 50%
- aabb= 2/4= 1/2.... Therefore aabb= 50%
Explanation:
The resulting F1 cross, AaBb, indicated that A is dominant over a, and B is dominant over b. Therefore a cross between AaBb and aabb would result to---
AaBb x aabb
= AaBb AaBb aabb aabb
Answer:
A. the movement of organisms from a native location to a foreign location
Explanation:
Creature relocation includes the development of a gathering of creatures starting with one spot then onto the next with goals of settling, for all time or for a brief time, at another area. They may come back to the area they first lived in or they might find it comfortable somewhere foreign. The response to the inquiry is choice A.
Climate, geology, topography, hydrology and soils all play a part in the formation and function of watersheds. These factors provide habitat, nutrients, flow and water quality that aquatic organisms need to survive.
Answer:
Explanation:
Paleontologists are scientists that use fossil records to study the history of life on earth. They use known evidence/fossils such as bones, prints (on land or sea), dead remains to determine evidence and history of past life on earth.
Some of there observations include the use of comparative anatomy to determine possible evolution. They also use carbon dating to determine approximately how long a fossil/bone has been in existence.
