Answer: It proposes that the entire double‑stranded DNA molecule serves as a template for a whole new molecule of DNA.
Explanation:
In semi-conservative DNA replication:
- a parent double-stranded DNA splits in two.
- Each strand serves as template, and then read by the enzyme, DNA polymerase, to ensure accurate synthesis of a new daughter strand for both
- the newly synthesized strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.
Thus, because the parent double strand is retained in the newly synthesized DNA, this model is described as semi-conservative
Answer:
The first blank can be filled with tagging. One of the procedures for studying the movements, biology, and migration of animals is known as tagging of animals. Tagging is utilized to examine the long-range irregular and regular movements of animals and to identify their life-span. All kinds of mollusks, vertebrates, and insects can be tagged.
The second blank can be filled with designate their area as a national park. Designation of the areas as a national park is one of the methods of conserving animals, like a tiger.
Explanation:
Answer:
Resilient landscape is defined as the property of landscape to mainatin itslef with desired ecological functions, biodiversity, and robust native. The property of grasses and plants that will help the Demaris family choose a resilient landscape are:
- Healthy root systems: It will saturate the ground water and will keep the wind from overbalancing the vegetation.
- Group of shrubs can reduce the wind hitting home in a storm.
- Trees with flexible trunks and limbs: flexible trunk of grasses are wind resistant and provide resilient landscape.
some of the type of grasses that provide resilient landscape are tall fescue, hybrid bermuda and perennial ryegrass et-cetra.
It refers to making or crating new genes in form of mutation
in duplicates of old genes. It is also a mechanism in major way through new
genetic material is generated during evolution. The duplication happens in
event termed unequal crossing over or recombination between misaligned
homologous chromosomes during meiosis.
Answer:
In the experiment conducted by Alisha to test the effect of different materials on the melting rate of ice, the dependent variable is the mass of the ice, and the independent variable is the type of cover material.
Explanation:
During an investigation or experiment, the dependent variable is the one whose changes will be studied, while the independent variable is able to influence the changes of the dependent variable.
In the case where it is wanted to <u>measure how different cover materials affect the rate of ice melting</u>, the dependent variable is the mass of ice and the independent variable is the coverage material, capable of affecting the time it takes for the ice to melt.
