Answer:
According to collision- coalescence theory, formation of raindrop from cloud droplets occurs when cloud droplets collide and coalesce or stick together.
Explanation:
- The only significant difference between a raindrop and a cloud droplet is that a raindrop consist of a velocity that is non-negligible during the fall.
- Larger droplets having higher terminal velocities fall faster and collide with smaller droplets. Often the cloud droplets stick together and coalesce to form a larger droplet.
- This starts a chain reaction where these bigger droplets fall even rapidly, collide with the other droplets in their path and merge with these droplets.
Answer:
Plants can cause mechanical and chemical weathering
Explanation:
Plants can cause mechanical and chemical weathering. When plants cause mechanical weathering, their roots grow into rocks and crack them.It can also happen in streets or sidewalks. When plants cause chemical weathering, there roots release acid or other chemicals, onto rocks, which then forms cracks, and breaks apart.

Answer:
4.
Explanation:
Synteny oe syntenic gene is defined as the physical co-localization of genetic loci on the same chromosome within a speciesand inidvidual.
In the beginning of the meiosis process, when genes are present in the same chromosomes but very far, they undergo indepedent assort due to homologous recombination and the random exchnage of matching fragment in homologous chromosomes takes place. During the crossing over there are very less chances that all types of gametes are produced accurate frequency.
Hence, the correct answer is 4.
I'm not sure if it's the "best" example but.
If your blood tempature is low, the hypothalamus will issues reflex commands that make your body shiver. If you are hot, you will sweat is the opposite of this.
Another example is, if your blood contains pyrokines then you might have an infection so you begin to run a fever as your body's way to kill the pathogen at the direction of the hypothalamus.
Hope these examples help!
