How would the geologic time scale be different if there wasn't any radioactive elements

Biology
1 answer:
liq [111]3 years ago
4 0

We won't know the absolute time of events.

Explanation:

The geologic time scale would have been a whole lot different because we would not have known the absolute time in which geologic events took place through time.

Geologic scale was based solely on the use of fossil records, rock units relationship and radioactive materials in them.

  • The fossil records and rock units only supplied the approximate ages in which events have occurred. The events were simply placed on relative order of occurrence and not precise date assigned.
  • Radioactive dating provides means of determining the exact date of formation of the rocks by studying the parent - daughter ratio in the rock.
  • Through this, numerical ages could be assigned to the rock.

An individual having two different alleles of a specific gene is described as being _________ for that specific trait.
borishaifa [10]

An individual having two different alleles of a specific gene is described as being Heterozygous for that specific trait.

You have a heterozygous genotype for that gene if the two versions differ. Being heterozygous for hair color, for example, means you have one allele for red hair and one allele for brown hair. The interaction of the two alleles influences which traits are expressed.

Being homozygous for a gene means you inherited two identical copies. It is the inverse of a heterozygous genotype, in which the alleles differ. People with recessive characteristics, such as blue eyes or red hair, are always homozygous for that gene. In genetics, heterozygous means having inherited different versions (alleles) of a genomic marker from each biological parent. As a result, a person who is heterozygous for a genomic marker has two distinct versions of that marker.

A process by which we shape and interpret sensory impressions in order to give meaning to our environment is​ ____________.
Alexxandr [17]

Answer:

Perception

Explanation:

Perception is usually defined as a collective process of accumulation, selection and interpretation, and organization of the sensory information. In simple words, it helps in the collection of information that is transferred from the different sense organs and interpreted by the brain. This collected information is used in understanding and interacting with the environment.

Thus, perception refers to the use of sense organs such as the nose, ear, eyes and making a person able to smell, hear and see things.
