Answer:
<em>The correct option is cell surface markers.</em>
Explanation:
The immune cells of our body detect foreign particles and generate responses so that our body can get rid of them. The foreign particles are often termed as antigens.
The immune cells such as antibodies possess cell surface receptors which detect the foreign objects or antigens. When the cell surface receptors detect any antigen they immediately recognize that a foreign particle has invaded the body and they then identify it and start to generate response.
Answer:
Codominance- its a relationship ebtween two versions of a gene. If both allels are domiant, it's called codominance.
Explanation:
The disk diffusion test is used to compare the effectiveness of antibiotics. The incubated plate (results) will show bacteria growth except where antibiotic has effects. The more effective the drug, the inhibition zone will be greater. So the most effective antibiotic is the one that has the largest inhibition zone around the test site.
Answer:
A gamete containing an extra chromosome is formed.
Explanation:
Geminal mutations may result in the production of mutant gametes. If such gametes fuse with those from another individual of the opposite sex to form a zygote, the mutation is transmitted to the progeny. A trisomy gamete containing an extra chromosome would transmit the mutation to the offspring after fertilization.
Large sources of fossil fuels are found in cold regions shows evidence of climate change.
<h3>What this map shows?</h3>
This map shows that large sources of fossil fuels are found in cold regions because fossil fuels are extracted from the living organisms body so in cold regions once there was a large number of organisms lived there. When they died the fossil fuel sources are formed.
So we can conclude that large sources of fossil fuels are found in cold regions shows evidence of climate change.
