Answer:

X-rays can do damage directly to DNA by ionizing bonds that are a part of the structure of DNA itself. However, part of the total damage done by X-rays is indirect damage caused by the production of water radiolysis product by the X-rays.

Answer:

Free radicals.

Explanation:

X-ray as an example of ionizing radiation.Like any ionizing radiation it produces free radicals  and reactive oxygen species when it interacts with biomolecules  e.g (DNA) in cells and tissues. Free radicals are atoms with unpaired  lone of electrons in  outermost shells. They are therefore  very reactive and always looking for  an unpaired lone of  electron to complete the outer shell. Thus radicals can be positive, negative or neutral in charges.

When an individual is exposed to  X-ray radiation,  hydroxyl free radicals,superoxide free radicals are produced .These radicals are damaging to DNA and cells.

E.g; the <u>hydroxyl  radicals</u> attacks the hydrogen atoms of the  deoxyribose sugar, disrupted the  ring structure and therefore the DNA structure leading to mutation.

Other radicals reaction involved addition reaction of the free radicals to the  Carbon atom in the sugar molecules ,and also addition reaction  on  the organic bases in DNA molecules, damaging the molecules.

PART 1


1. The answer is low frequency electromagnetic waves are able to go around obstacles due to their larger wavelengths. This characteristic of lower frequency waves is due to their ability to diffract around obstacles such as buildings and hills. Therefore, they transmit over long distances unlike high frequency electromagnetic waves.

2. One disadvantage is interference. Electromagnetic waves of the same frequency transmitted at the same time will interfere with one other and therefore the signal will be lost or scrambled. Other electromagnetic waves such as microwaves are affected (interfered with) by weather elements.

3. Analogue signals are continuous signals with wave-like properties while digital signals are discrete signals or pulse (ons (1s) and offs (0s) that represent bits). Analogue signal is represented by a sine-wave while digital signal is represented by discrete squares waves.

4. Digital signals are less immune to eavesdropping unlike analogue signals. Analogue signal is also more prone to distortion unlike digital signal. Digital signals transmit more data than analogue signals. Digital signal draw less energy to transmit compared to analogue signal.

5. Broadcasting of TV is nowadays using digital signals due to the high number of available channels. Computers and the interne utilize digital signaling to transmit data. Controls systems such as radar system also use aspects of analogue waves. Sensors also utilize analogue waves especially transducers such as seismology equipment.


PART 2


1. One way is by sending radio waves to probes sent out in space to give them commands during exploration. Radio telescopes also pick up naturally-occurring radio waves from space and analyze the data to make conclusions about space and the astronomical objects.

2. Radio waves are used in communication by transmitting data over long distances. One example is its use TV transmission. Another is through military defense of airspace. The radio waves are used to detect enemy intrusion into restricted airspaces using radar.

3. It is common that signal from the environment will be in analogue signal format. The conversion to digital signals allows for the digital equipment in the telescope to interpret and analyze the data. Telescopes prefer digital equipment because they consume less power, handle more data, and are less prone to intrusion, and distortion, hence more secure to analogue equipment.

The ostrich is a bird. However, it has traits that are different from those of the birds we typically see flying around our neig
Romashka-Z-Leto [24]

Answer:

I found this from someone else. This is not my work, Also if this does not answer the question ask the question on here and you can see more answers. hope this helps.!

Explanation:

According to National Geographic, ostriches are a part of a very small group of birds that cannot fly because unlike most birds, their small wings are not strong enough to carry their body for flight and their breastbone isn't balanced enough for flying. Birds that are unable to fly are called ratites.

A number of scientists namely Thomas Huxley, Richard Owen, and others have tried to show that these ratites are actually related to each other and eventually, it was discovered that they all had one thing in common, the way the bones at the roof of the mouth were arranged was similar to that of reptiles rather than other birds.

Richard Owen found and assembled the remains of an extinct ostrich skeleton which was an extinct moa and contrary to already held opinion, one ratite known as tinamous did not really fit with the profile of a ratite because it could fly, even though almost grudgingly and they possessed keeled sternum which suggests that they evolved from flying birds.

DNA tests showed that tinamous evolved within ratites and not necessarily as a separate entity. The tests also showed that moas and tinamous are related.

It was also speculated that the division of the supercontinent Pangaea southern side led to the separation of flightless ratite ancestors, causing each landlocked group to evolve and become the flightless birds we know today such as the ostrich, rheas, etc.
