The vocal cords vibrate when air passes over them. This produces the sound of your voice.
The male
human has a sperm cell and the female has an egg cell. The cells from the male
and female that combine to form a zygote are called gametes. The human sperm
and egg cells each contain 23 chromosomes. . A combination of gametes forms a
zygote with 46 chromosomes. The type of cell division that produces gametes
with half the normal chromosome number is the meiosis. Meiosis is the type of
cell division used in sexual reproduction. It will occur in the testes and
ovaries.
Answer:
C) Messenger RNA is transcribed from a single gene and transfers information from the DNA in the nucleus to the cytoplasm, where protein synthesis takes place.
Explanation:
Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product, usually protein. Gene expression include steps such as
• transcription – part of DNA is copied into mRNA via an enzyme RNA polymerase
• RNA splicing – formed mRNA during transcription is not mature so it need to be proceed (e.g. excision of introns). Mature mRNA are then exported from nucleus to cytoplasm
• Translation – mRNA serves as information that codes for the synthesis of one or more proteins.
Answer:
A normal type of white blood cell that has coarse granules within its cytoplasm.
Answer:
· Nitrogen fixation
· Nitrification
· Assimilation
· Ammonification
· Denitrification
Explanation:
Nitrogen fixation is the process where nitrogen is converting into ammonium.
Nitrification is the process of ammonium oxidation into nitrate.
Assimilation is the process where animals and plants receive NO3. Plants are using this nitrate for proteins and acids.
Ammonification is the process where the nitrate that is contained in plants and animals is recycled after their death.
Denitrification is e the last process in this cycle and during this process nitrate is converting to gases.
