Why is it important for geologists to use both relative and absolute ages to determine the age of rocks?
uysha [10]

Answer:

to help and determine the exact age of the rocks

Explanation:

The study of rocks strata is known as stratigraphy. It is useful and helps the scientist and the researcher to study the earth's crust and its past.

Scientist could age the rock using two methods. They are :

Relative ages

Absolute ages

Early scientist could determine the exact age of the rock of the earth's crust. They use to find the relative ages of the layers of the rocks and then determine how one rock layer is older or younger than the other. But with advancement and development of carbon dating, scientist could tell the exact age of the rocks found on the earth's crust.

The Scientists uses the relative as well as the absolute dating technique to date the rock layers. They organize the rock layers based on their age and scale from the oldest to the youngest on a geologic time scale. So an exact date of the rocks can be determine by using the two methods of relative age and the absolute age.

Mendel crossed plants that produced only round seeds to those that produced only wrinkled seeds. In the next generation, all the
Artist 52 [7]

Answer:

Dominance

Explanation:

Mendel discovered certain principles that governs heredity or inheritance when he conducted experiments. In his experiments, he discovered that an organism receives two copies of a gene called allele, from each parent.

He discovered that one allele of a gene has the ability to mask or suppress the expression of its allele variant in the same gene. He called the allele that masks or is expressed, DOMINANT allele, while the allele that is masked, RECESSIVE allele. Based on this observation, he named his first principle, LAW OF DOMINANCE.

In this case, he crossed a purebreeding round-seeded pea plant and a purebreeding wrinkled-seeded pea plant, he noticed that in the F1 generation, all the offsprings possessed round seeds. This led to the conclusion that the allele for round seeds masks the phenotypic expression of the wrinkled allele in a heterozygous state. Hence, the allele for round seeds is dominant while the allele for Wrinkled seeds is recessive.

Rama09 [41]

Answer:

Transpiration is loss of water from the surface of leaves in the form of water vapour while guttation is exudation of water from the surface of leaves in the form of drops. Transpiration takes place through stomata while guttation takes place through hydathodes.

Guttation usually occurs at the margins and the tips of the leaves. Transpiration occurs throughout the general surface of the leaves and the young stems.
