Answer:
1. Radiometric dating
2. Relative dating is used to determine the age of fossils or rock layers by by comparing it to similar rocks and fossils of known ages.
3. The youngest rock layers are at the top and the oldest are at the bottom, which is according to the law of superposition.
4. Tribolite and Pecten fossils
Fossils are used to determine the ages of rock layers. Index fossils are the most useful in determining relative aging. Index fossils are of organisms that lived for a short period of time. An index fossil allows a scientist to determine the age of the rock it is in. So if they are found in a particular age, it means they belong in that age.
5. Scientists commonly use radioactive dating methods by using radioactive decay cloak of certain elements such as potassium or carbon to date fossils or rocks.
6. Law of superposition because in terms of finding the age of the rock as an object, all that needs to be identified are the layers of the rock.
7. The nuclear decay of radioactive elements are a process that behaves in a clock-like fashion which makes it a useful tool for determining the exact age of fossils or rocks.
Answer:
nope that not possible because O has no antigens which can donate any blood group but A donates to same blood group bcoz of same antigen.
Answer: the answer is <u><em>A</em></u>
- Explanation: Because bears know that every time they go for food near the picnic <u>they will find some</u> there
The theory of Natural Selection was accepted after it got consensus from
scientists.
<h3>What is natural selection?</h3>
The theory of Natural selection defines the process in which individuals who adapts to their environment survives and reproduce more offspring.
- This theory was proposed by a scientist called Charles Darwin and Alfred Russel Wallace who also had the idea of evolution.
- This two scientist work together to publish a book on new evolutionary theory titled On the Origin of Species (1859). This is because they believed evolution occur through natural selection.
In this theory, organisms produce offspring but not all offspring survive this because they all struggle to live.
survival is based on survival of the fittest. some of those who survive can reproduce their kind while some do not grow to maturity and are loss.
Therefore, The theory of Natural Selection was accepted after it got consensus from scientists.

Answer:
The options have been placed in the comment section. The answer is C. Inheritance of genes from both parents
Explanation:
Gregor Mendel is referred to as the FATHER OF GENETICS due to his immense contribution to the discovery of how traits are passed down or inherited from parents to offsprings. He found out that a unit of inheritance, which was later called GENE, was responsible for each individual trait of pea plants.
In his numerous experiments, Mendel discovered that the characteristics/traits of pea plants were determined by the contribution of both parents. Mendel hypothesized that each parent contributed 50% of this unit of inheritance via fertilization to the characteristics of an offspring. Hence, the inheritance of genes from both parents determines the characteristics of a pea plant.
