Asexual reproduction is a type of reproduction that only requires one parent. The offspring only have the characteristics and traits from that parents. They create “clones” if you will. This is the most common form of reproduction for single cell organisms like prokarayotes and bacteria.
Here are the advantages:
1. Rapid Populating
Asexual reproduction gives the ability to produce large quantities of of offspring. This helps to fill up niche’s quickly and prevent intruders and competition from invading.
2. No Mates Required
Finding a mate can be very difficult for organisms that are in desolate environments, like the deep ocean. Asexual reproduction takes the need to find a mate away, allowing these organisms to multiply.
3. In Case of Emergency
In dire situations, plants and organisms can keep themselves alive and produce others to help them without the help of a mate, or other reproductive source. Plants are a great example of this. If no pollinator is available to pollinate, then they can clone by asexual reproduction.
4. No True Investment
Asexual reproducers do not have to carry their offspring for a long amount of time and produce more than one at a time. This makes it a quick and inexpensive process for them in the terms of time.
Here are the disadvantages:
1. No Diversity
Since the traits of only one parent is passed on, all of the offspring are exactly identical. This causes for a very big lack of diversity among the population of these organisms.
2. Prone To Extinction
All of the same traits also means all of the same weaknesses. Parasites and other predators that have evolved to kill just one of the organisms can take out the entire population.
3. Cannot Adapt
An organism has established reactions to certain things, and all of these reactions are passed down to their offspring with asexual reproduction. This makes it impossible for them to adapt to any environment changes.
Answer:
Electromagnetic radiation
Explanation:
Answer:82. Since you have a distance and a force, then the easiest principle to use is energy, i.e. work.
The work done by friction is F * d. This work cancels out the kinetic energy of the stone (1/2)mv^2
Fd = (1/2)mv^2
F = (1/2)mv^2/d.
Plug in m = 20 kg, v = 3 m/sec, d = 40 m.
83. With more mass, the kinetic energy is higher now. The work needed is higher. W = F * d and F is the same.

Answer: Gravity is the force that keeps planets in orbit around the Sun. Gravity alone holds us to Earth's surface.
Planets have measurable properties, such as size, mass, density, and composition. A planet's size and mass determines its gravitational pull.
A planet's mass and size determines how strong its gravitational pull is.
Models can help us experiment with the motions of objects in space, which are determined by the gravitational pull between them.
