<h3>Answer:</h3>

C) reflection.

<h3>Explanation:</h3>

In the picture shown above, the incident ray is equal to the reflected ray. According to the law of reflection, the angle of incidence is equal to the angle of reflection. Therefore, the property of light shown above is a reflected ray.

What is an example of codomiance
satela [25.4K]

Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.

which is an example of biodiversity 900000 fires, deforestation, thousands of species carbon dioxide?
stira [4]

Answer:

Thousands of species is an example of biodiversity.

<u>Explanation: </u>

<em>Biodiversity is the short term for biological diversity which was coined by E.O. Wilson</em>. <em>Biodiversity refers to all the species of plants (flora) and animal Kingdom (fauna) present on the Earth.</em> It covers different types of ecosystems present in a well-defined area whether it be terrestrial or aquatic and the genetic variability within a species.

The variety of crops and livestock present on Earth have played a great role in human development. Without them, life would not be possible. That’s why it is our moral duty to conserve our biodiversity. If we preserve it for our future generations, we will survive.  If they are overused or misused, the entire food chain would perish.

Each ABO blood group is associated with the presence/absence of RBC antigens and the presence/absence of antibodies in the plasm
harina [27]

Answer:

a. Type O blood - No A or B antigens on RBCs-Anti-A antibodies in plasma-Anti-B antibodies in plasma

b. Type A blood - A antigen on RBCs- Anti-B antibodies in plasma

c. Type B blood - B antigen on RBCs- Anti-A antibodies in plasma

d. Type AB blood - A antigen on RBCs- B antigen on RBCs- Neither anti-A or anti-B in plasma

Explanation:

ABO blood grouping system represents multiple allelism which was discovered in humans by Karl Landsteiner. The blood group is determined by the presence or absence of A & B antigens and antibodies.

The 4 blood groups which exist in ABO system are O, A, B and AB. Also, allele A and B are co-dominant i.e. if they both will exist on the surface of an RBC then both will be equally expressed which implies that there will be no dominant or recessive allele.

Type O blood group has H antigen on the surface of RBC and has both the antibodies i.e. antibody A and B. The absence of antigens A and B makes it a universal donor.

Type A blood group has A antigen on RBC and has antibody B in the plasma.

Type B blood group has B antigen on RBC and has antibody A in the plasma.

Type AB blood group has both the antigens i.e. antigen A and B on RBC and does not have any antibody in the plasma which makes it a universal acceptor.

Many scientists believe horizontal gene transfer (HGT) is a significant source of genetic variation. Why
lawyer [7]

In prokaryotes, horizontal gene transfer (HGT), the transfer of genetic material from one organism to another organism within the same generation, is an important way to promote genetic diversity. HGT allows even distantly related species to share genes, influencing their phenotypes.

Transformation: Mode of genetic transfer in which “bare DNA” is taken up from the environment is taken up by cells

Transduction: Mode of genetic transfer in which genes are transferred by a bacteriophage to a bacterial cell

Conjugation: Mode of genetic transfer in which two cells must come in contact and genetic material is transferred to a recipient cell from a donor cell through its pili
