Answer:

Explanation:

The DNA fingerprinting technique and development and comparison of physical fingerprints can be the methods used for the purpose of solving crimes and identification of missing person.  

The DNA fingerprinting can be done from the physical evidences such as blood, sweat, hair, tissues, teeth and other material obtain at crime scene. These can be compared with the suspects, victim and missing persons so as to establish their identity.

The physical fingerprints can be developed on the scene of crime and compared with the requested specimen from suspect, victim and the missing person or in case of impersonation to establish the desired identity.

balu736 [363]

Answer:

Environment

Explanation:

B.F Skinner was of the belief that the environment of a person drove or influenced his behavior. His opinion was that human beings have a particular way of behaving which requires special kinds of responses and that as this goes on, humans will adapt and start behaving in a certain kind of way.

In a population of tomato plants mean fruit weight is 60 g and narrow-sense heritability (or realized heritability - h2) is 0.3.
Alla [95]

Answer:

The mean weight of the progeny is 66 grams

Explanation:

Given -

Mean fruit weight of tomato plant (M1) = 60 g

Narrow sense heritability (h2) = 0.3 g

Mean weight of tomato plant selected for artificial selection (M0) = 80 g

h_2 = \frac{M_2 - M_1}{M_0 - M_1}

Substituting the given values in above equation, we get -

0.3 = \frac{M_2 - 60}{80 -60} \\0.3 = \frac{M_2 -60}{20} \\6 = M_2 -60\\M_2 = 6 + 60\\M_2 = 66

The mean weight of the progeny is 66 grams

Axons cross from one side of the spinal cord to the other through the
Airida [17]
<h2>Axons </h2>

Explanation:

Axons cross from one side of the spinal cord to the other through the gray commisure

  • Each arm or extension of the gray matter in the spinal cord is referred to as a horn
  • Projecting towards the back of the spinal cord are the dorsal horns (or posterior horns)
  • Projecting towards the front are the ventral horns (or anterior horns)
  • In the thoracic and upper lumbar regions of the cord, an additional pair of side projections occur, which are called the lateral horns
  • A narrow band of gray matter known as the gray commissure stretches across of the center of the spinal cord and connects the two sets of horns
  • In the middle of the gray commissure is the central canal, which contains cerebral spinal fluid

Te technique can reach tall forests.

It can be used in closed spaces ( greenhouses, basements etc).
