<em>Answer:</em>
Thrust and Lift.
<em>Method:</em>
There are 4 forces acting upon a plane while it is moving. Drag (The air friction while it's in the air), Lift (Generated by the wings (The upward force), Weight (How heavy the plane is), and finally, Thrust (Generated by the engines which moves the plane/wings through the air generating lift). If there is enough air going over the wing at a high enough speed, and Thrust, and Lift overcome the other two forces keeping the plane on the ground, it can fly. The air pressure under the wing is higher than over the wing - If you have ever ran you hand under the water keeping it flat, you may notice it going up, those are basically the same forces, but under water.
How does the pressure under the wing affect the lift?
The difference of air pressure over the wing (which is less), which also means less force bringing the plane down. The air pressure under the wing is higher, putting pressure on the wing moving it up. A wing is designed to make the air travel a longer distance over the wing than under the wing creating the air pressure. The engines just enforce that process.
Answer:
All these factors affect gene flow:
1. Differences in animal behavior and life history strategies can form effective barriers to gene flow.
2. The home range size of the specie can also serve as a barrier to gene flow.
Explanation:
Firstly, gene flow is the transfer of genetic traits from one population to another. It is an important process for transferring genetic variations from one population to another.
There are several barriers or factors that limit or increase this gene flow.
Gene flow can be affected by mobility or rate of dispersal. It is expected to be lower in species with low mobility which is the movement from one place to another or low dispersal and vice versa. So a population with a shorter home range size can't effective aid gene flow as they interact only with individuals of the same population and vice versa.
Gene flow barrier could be by physical barriers which is the isolation of a geographical location preventing them from exchanging genetic materials with the same species of the sane population.
This type of physical barrier is usually but not always natural.
Barrier to gene flow could be reproductive preventing transfer of genectic materials due to differences in mating period, season of birth and so on.
Another barrier could be difrerneces in customs, ethnicity, religion and clans.
All these factors affect gene flow but the 3rd and 4th option are not totally true as barriers to gene flow are not totally physical geographical barriers and not totally anatomical differences but also soil preference and other factors.

A. Burning natural gas
A liquid changing to gas is called boiling or evaporation.A gas change into a solid is called deposition and a gas changing into a liquid is called condensation.half of these are endothermic, meaning they absorb heat from their surroundings.the others are exothermic,meaning they release heat. Hope this helps
Answer: Posterior HoxA and HoxD genes play important roles in patterning along the proximodistal axis of the forelimb (10–13). They also are required for activating and maintaining Shh expression in the developing forelimb (6, 7). mark brainliest
