ANSWER: Biological biodiversity refers to all the different kinds of life that are obtainable in a particular ecosystem, this include all the plants and animal populations that are found in a particular geographical area.
Biodiversity supports healthy ecosystem because it enhances the productivity and the survival of the ecosystem. For instance, in a situation where there are large number of different plant population in an ecosystem, such population will present variability in genetic make up. If a negative event occur in the ecosystem, it will be possible for some plants to survive. But, in a situation where it is only one type of plant that is obtainable in the ecosystem, it will be quite easy to wipe all of them out at once. For instance, a disease outbreak can easily destroy all the plants.
Answer:
The fundamental law of inheritance.
Explanation:
He is responsible for our knowing that genes come in pairs and are inherited as units (alleles), one from each parent.
Era is used to mark the boundaries of geological time scale by using radio carbon dating technique.
Explanation:
Geological time starts with Precambrian time.
Geologically, time is divided between the Precambrian era and present time into era.
The three eras are Paleozoic era, Triassic period and Cenozoic era.
Era is further divided into periods.
Scientists use radio carbon dating to study fossils and rock formation. With this study they were able to divide them in exact geological scale.
Geologic scale is the record of events in earth's history and evolution.
Answer:
Two
Explanation:
Consider the sequence ATGACATGCAATTGA.
Originally, there are 5 codons, translating to a minimum of 5 amino acids: ATG CAT GTC AAT TGA.
A base was inserted after the first G and the third T was deleted, the sequence become (assuming A is the inserted base);
ATG <em>ACA TGC</em> AAT TGA
<em>Only the second and the the third codon are changed and hence, their respective amino acid.</em>
