Amniocentesis or Amniotic Fluid Test or Amnio is the process to examine genetic defects, fluid infection or sex determination by inserting a needle into the Amniotic fluid surrounding the unborn fetus.

<u>Explanation:</u>

<u>Amniocentesis</u>

Amniocentesis is a prenatal diagnosis which is used to determine genetic defects, fluid infection or sex determination by inserting a needle to draw a small sample of fetal cells through the amniotic fluid surrounding the unborn fetus.

The prime aim of Amniocentesis is to detect chromosomal deficiencies and cure the fetus with all possible processes so that the baby may be normal and healthy at the time of delivery.

This process is performed when the woman is 15-20 weeks pregnant. The test has the tendency to spread quick and possesses the probabilities of miscarriage.

What is the mass of all the worker bees in the hive together? Write your answer in scientific notation.
Lisa [10]

Answer:

4 × 10^0 kg or 4×E0 kg.

Explanation:

Before delving into or solving the Calculation, let us check one or two things about worker bees.

WHAT IS A WORKER BEE?.

Bees generally are social insects living in an organized community and they consist of three castes which include; the drone bees, worker bees, and the queen bees.

The queen bees are the female bees while the drone bees are the male bees.

The WORKER BEES are female bees too, but the only difference between them and the queen bees is that they (worker bees) do not reproduce like the queen bees. They are saddled with the responsibility of looking for food and maintaining the hive temperature.

Now to the question, the mass of a bee= 1 × 10^-4 kg. And there are 4 × 10^4 bees in hive. Therefore, the mass of all the worker bees in the hive together = (1 × 10^-4) × (4×10^4).

==> 4 × 10^0 kg, or 4E0 kg.

<h2>Answer is option "b"</h2>

Explanation:

  • Non-ionizing radiation is radiation that has a lower frequency, or longer wavelength, in the EMR spectrum. These frequencies range from that of power lines, radios, and cell phones, up to visible light. Non-ionizing radiation is not powerful enough to break the chemical bonds in molecules. In general, it is not harmful to human health as radiation per se, but could be harmful in terms of the transfer of heat energy. An example of an emitter of non-ionizing radiation is a microwave oven.
  • Non-ionizing radiation is less harmful because the rays carry much less energy. Radio waves, light, and even heat are examples of non-ionizing radiation. For the most part, these kinds of radiation do not cause any damage. However, ultraviolet light is a kind of non-ionizing radiation that can be harmful - it can cause mutations in DNA
  • Non-ionizing radiation is limited to the lower energy range electromagnetic radiation, which is more commonly known as light. However, the light we can see with our eyes, visible light, is only a small section of the electromagnetic radiation spectrum as seen here
  • Hence the right answer is option "b"
