Gametes, or sperm and egg cells are both haploid cells, meaning that they have half the amount of chromosomes that regular body cells do, meaning that the sperm cell of this bird would have 32 chromosomes.
Answer:
The correct answer is a. the photosynthetic part of a lichen.
Explanation:
Lichen is a symbiotic association in which the algae and fungi are associated with each other. Fungus can not make there own food so they are not photosynthetic like algae or plants and in lichens algae are the photosynthetic part while fungus plays the role of absorbing nutrients for the algal partner.
Lichens are found all over the world and they absorb industrial pollution very quickly so are also referred to as pollution indicators of the environment as they do not grow in a polluted area.
Therefore the photosynthetic part of lichen is algae, not fungus so the correct answer is a.

Answer:
Transcription is the synthesis of RNA from the DNA. It is further divided into three steps:
Initiation: In this step at first, there is binding of RNA polymerase to the group of transcription factors, it binds at the promoter. It is followed by unwinding of DNA double helix, and then the synthesis of RNA starts.
Elongation: The RNA polymerase extends across the DNA template, it adds the base pairs in 5' to 3' direction. In the same step proofreading of RNA is done to eliminate the errors in synthesis.
Termination: In this step RNA polymerase detaches, at certain stop signals, adding of further base pairs is also terminated by RNA polymerase. The newly synthesized transcript of RNA is released.
Answer:ANSWER: C. Complementary base pairing occurs only between the probe and the target gene.
