Where does photosynthesis take place in the leaf?
Darina [25.2K]

Answer:

in the chloroplast

Explanation:

In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.

Explain the difference between the term evolution and<br> biological evolution?
stiv31 [10]
Evolution is a broader use of language terminology. Biological evolution refers to the evolvement of a particular biological species such as an animal or a plant. On the other hand evolution can refer to the evolution of anything. There are no constraints on what it is being preferred to.

** ALL MY POINTS**
Flura [38]

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.

describe the change in overall shape of the molecule caused by the introduction of a carbon-carbon double bond
castortr0y [4]

The introduction of a carbon-carbon double bond would cause a overall structure of the molecule to bend.

Carbon-carbon bonds are the type of bonds seen in hydrocarbon compounds which consists of two carbon atoms that has covalent bonds between them.

Covalent bonding occurs between atoms that share the electrons in their outermost shell to achieve an octet shape like the noble gases.

When there is an introduction of a carbon-carbon double bond, it leads to the bending of the overall linear structure.

This bend that is caused by the double bond is often referred to as "cis" and leads to a change in some physical properties of the molecule such as :

  • decrease in melting and

  • boiling points.

Therefore, the introduction of a carbon-carbon double bond would cause a overall structure of the molecule to bend.
