adaptations.
Natural selection leads to traits called adaptations, which improve an organisms ability to survive and reproduce.
Answer:
Option A, Viruses contain either DNA or RNA.
Explanation:
Virus is a non-living microscopic molecule that requires a host to live in and reproduce. All the viruses have nucleic acid either in the form of DNA or RNA. DNA or RNA is genetic material that is enclosed with in a membrane known as capsid. Capsid is also made up of protein. They are extremely small, even smaller than a normal cell and only consist of package of nucleic acid and protein.
Hence, option A is correct
1. 50% will have the RR phenotype and 50% will have the Rr phenotype.
2. 25% will be RR, 25% will be rr and 50% will be Rr
3. 100% will be rr
Yes, because natural selection is when only those whose alleles are made for the organisms' fitness
Answer:
Fermentation
Explanation:
Fermentation is a catabolic, anaerobic process, which is not usually accompanied by electronic transport and whose final product is an organic compound. Yeasts are unicellular bodies (generally spherical in shape) with a size of around 2 to 4 μm and that are naturally present in some products such as fruits, cereals and vegetables. They are what are called: facultative anaerobic organisms, that is, they can develop their biological functions without oxygen. Yeasts carry out alcoholic fermentation. Its biological purpose is to provide anaerobic energy to unicellular microorganisms (yeasts) in the absence of oxygen, to dissociate glucose molecules and obtain the energy necessary to survive, producing alcohol and CO2 as fermentation waste.
