Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire. In wireless systems, this length is usually specified in meters (m), centimeters (cm) or millimeters (mm).

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.

A motorboat traveling from one shore to the other at a rate of 5m/s east encounters a current flowing at a rate of 3.5m/s north
nikdorinn [45]

Answer:

Resultant velocity will be equal to 6.10 m/sec

Explanation:

We have given a motorbike is traveling with 5 m/sec in east

And a current is flowing at a rate of 3.5 m /sec in north

We know that east and north is perpendicular to each other

So resultant velocity will be vector sum of both velocity

So resultant velocity v=\sqrt{5^2+3.5^2}=6.10m/sec

So resultant velocity will be equal to 6.10 m/sec

Global Precipitation Measurement (GPM) is a tool scientist use to forecast weather. Which statements describe GPM
klio [65]

Answer:

Correct answers:

Explanation:

• It is a satellite that collects data about rain and snow.

GPM is part of NASA's Earth Systematic Missions program and its function is to track precipitation from space with satellites and to provide accurate information of the time, place an amount of rain or snow anywhere in the world.

• Its orbit covers 90 percent of Earth's surface.

 GPM has unique perspective on measuring precipitation from space because of their collected satellite retrievals.

• The sensors measure microwaves.

GPM Microwave Imager (GMI) is a sensor that observes the microwave energy emitted by the Earth and atmosphere, so it improves the accuracy of rain and snowfall estimates.

Why does trapped air in a vacuum flask reduce heat loss by conduction?
harina [27]
Having a vacuum prevents conduction from occurring completely bc there are no molecules to transfer the heat...since air is a poor conductor of heat, having trapped air in the sponge and hollow plastic stopper help prevent heat loss by conduction
