Nonrenewable resources and found it fixed amount hence not managing properly will lead to full use of it and cannot be replaced
Explanation:
- Nonrenewable resources are found in the ground and they are the natural resources created by nature
- It includes fossil fuels, like natural gases, oil, coal, etc and also the minerals used for making metals
- These natural resources have taken more than human's life span to form, up to million years. Hence, replacing of these natural resources are not possible
- Renewable natural resources are trees, water, air. These resources can be recycled and they are also circulating in the atmosphere in the form of a cycle.
- Hence, nonrenewable resources should be managed properly for it last for the coming generations.
<h2>
Meselson and Stahl conducted an experiment to determine the correct proposed methods of DNA replication was semi-conservative
. the three proposed models for DNA replication are semi-conservative, conservative, and dispersive.</h2>
Explanation:
In Semi-conservative replication model, the two strands of DNA uncoil from each other. It perform with the original strand and a new strand.
In Conservative replication model, DNA replication didn't open at all, but the parent strands remains undamaged by creating a new and separate molecule that consists of two new strands.
In Dispersive replication model, DNA replication results in two DNA molecules that consists of both parental and daughter DNA.
He demonstrated that semi-conservative DNA replication is an universal mechanism allocated by all organisms on Earth.
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.
