Biology
1 answer:
Fynjy0 [20]3 years ago
3 0
This condensation is needed to allow the chromosomes to move along the mitotic spindle without becoming tangled or broken during their distribution to daughter cells. DNA in this highly condensed state can no longer be transcribed, so all RNA synthesis stops during mitosis.

As the sky diver falls to earth, she experiences positive acceleration due to
Sauron [17]

Answer:

The gravitional pull of the Earth

Explanation:

Anything that has mass also has gravity. Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Since the earth has more it will cuase you to be, almost attracted by it.

Also, Gravity is inversely proportional to the square of the distance that separates the two bodies. Hence gravity will decrease as one will go higher in altitude, and hence away from the center of mass.

But since your falling from a plane, or some other type of aircraft, your moving closer to the center of mass, hence your gravitational pull get stronger as you falling closer-and-closer to the ground.

How are the reproductive cycles of a fungus and a pteridophyte similar?
Rudik [331]

The answer is; A

In pteridophytes, the sporophytes (of the haploid stage) produce spores. The diploid stage in pteridophytes may occur when tow spores fuse and develop into a prothallus (diploid stage of the pteridophytes).

Fungo too produces spores by the sporangiophores (haploid stage). Occasionally, two horizontal hyphae between two species of fungi, may fuse at the tips and form a zygote through karyogamy and plasmogamy.

Ad libitum [116K]
Spray drying is a process in which a liquid containing dissolved or suspended solids is sprayed through a nozzle into a chamber in which hot air is being blown into at the same time. As the nozzle releases small drops of the solution, it comes in contact with the hot air and the moisture content of each droplet is removed. This way, the liquid is turned to powder form which moves to a conveyor belt at the bottom of the chamber.
