Answer:
Disease- and drought-resistant plants that require fewer environmental resources (such as water and fertilizer) Less use of pesticides. Increased supply of food with reduced cost and longer shelf life.
Electromagnetic waves are waves propagated by simultaneous periodic variations of electric and magnetic field intensity that include radio waves, infrared, visible light, ultraviolet, X-rays and gamma rays.
Damped oscillation means that there is some force that causes the oscillation to become smaller and smaller over time. For example, the pendulum exhibits an oscillation motion. Over time, the swinging of pendulum would come to a stop, unless a force is acted on it.
Forced oscillation means that an outside force causes an object to oscillate at a certain frequency. For instance, if you decide to swing the pendulum so that it won't stop from swinging, the action is called forced oscillation.
On the other hand, resonance oscillation refers to the increase in an amplitude of oscillation of an electric or mechanical system exposed to a periodic force whose frequency is equal or very close to the natural undamped frequency of the system.
Among the three types of oscillation, resonance is most likely to produce an electromagnetic wave.
Answer:
<em>Vacuole</em>
Explanation:
Vacules are the storage bubbles within the cell. They store food, nutrients and/or other organic compound which might cell require during starving conditions. They are more than one in animla cells but relatively smaller. The diagram shown is the schematic representation of the animal cell.
Answer:
Non- targeted cell lacks intracellular receptor for these hormone.
Explanation:
Receptors that are found on the cell surface are called cell surface receptor and those which are found inside the cell are called intracellular receptors. Intracellular receptor binds to lipophilic molecules. Each receptor binds specifically to a particular ligand or signal molecule.
So even though testosterone and estrogen can diffuse in every cell they will only affect those cell which have specific receptor which can bind to these hormones and then regulate the transcription of a specific gene in the nucleus.
So only those cells will respond to testosterone and estrogen who have specific intracellular receptors for them.
Answer:
It must encode the blueprint to form proteins and other structures.
It must be able to replicate and transmit to progeny.
It must have heritable traits that can be passed to offspring.
Explanation:
The genetic material in most living cells is stored as Deoxyribosenucleic acid (DNA). It is one of the two types of nucleic acids that are made up of nucleotide subunits, the other one being RNA.
Every genetic material in living organisms consists of segments called GENES that encodes the formation of functional products e.g protein and RNA. These gene undergoes expression to be converted to what it encodes.
Another attribute the genetic material should possess is the ability to double it's content during cellular division in order for each daughter cell to receive an equal and correct amount of it. This duplication of genetic material occurs during the S phase of the interphase stage.
The genetic material (genes) must be able to hold information and pass the genetic traits to the offspring during reproduction.
