Answer:

<u>Kinetic energy:</u>

"The form or phase of energy which is possessed by the body due to its motion or state of its motion."

  • <u>As the mathematical formula for K.E energy is;</u>
  • K.E=1/2 m×v²,⇒(1)

Explanation:

Now, we have the following data, in the given problem:

  • Velocity,v=4 m/s,
  • Mass,m=7 kg,
  • K.E=?,
  • <u>Solution:</u>
  • So, putting the values inside the equation(1),we will get the following answer:
  • <u>K.E=</u>1/2×(7)×(4),
  • K.E=1/2×28,
  • K.E=28/2,
  • <u>K.E=14 Joules(or in other unit kg m²/sec²).</u>

Answer: The kinetic energy of the flying bird is 56 Joules.

Explanation:

Mass of the bird  = 7 kg

Velocity of the flying bird = 4 m/s

Kinetic energy of the bird will be given by :

K.E.=\frac{1}{2}mv^2

K.E.=\frac{1}{2}\times 7 kg\times (4 m/s)^2=56 Joules

The kinetic energy of the flying bird is 56 Joules.

In which reproductive cycle of the virus does the viral DNA integrates with the host DNA?
zzz [600]

Answer:

Bacteriophages have a lytic or lysogenic cycle.

Explanation:

The lytic cycle leads to the death of the host, whereas the lysogenic cycle leads to integration of phage into the host genome. Bacteriophages inject DNA into the host cell, whereas animal viruses enter by endocytosis or membrane fusion.

Exposure to teratogens after organogenesis is complete may most likely result in select one:
Ivenika [448]

The teratogens can be defined as any physical, chemical, or infections agents that have the ability to penetrate the protective layers of the embryo, and affect its viability. The overall development and the development of the different organ systems might be affected because of these teratogens. When the embryo is exposed to the teratogens after the organogenesis is complete, it is most likely that the fetus will suffer from the stunted growth. When the organogenesis is complete, the organs are already formed, and hence, no severe damage can occur to them. Down's syndrome will result if the chromosomal abnormality occur in the fetus, which is not likely after the organogenesis is already complete. Any kind of severe anatomical defects are also least likely after organogenesis is completed. Therefore, the chances of having stunted growth are high.
