determine the ____
age of rocks
Answers
Answer:
The correct answer is - precise.
Explanation:
Radiometric dating or radioactive dating used to determine the precise age of rocks or fossils. It is also known as absolute dating. This uses radioactive minerals found in the rocks or fossils similar to the geological clock.
The radiometric method on the basis of the mineral can be used to determine the different ages of rocks. For instance, Carbon dating used to determine up to 50000 years old rocks whereas Uranium–lead dating, used to date rocks that formed between 1 million years to over 4.5 billion years ago.

In the snapdragon example, what third phenotype is expressed from the heterozygous genotype?
Red flowers
pink flowers
white flowers
Answers
Answer:
Pink flowers, a blending of red and white
The correct option (B) pink flowers.
How is the color of flower controlled?
In snapdragon the color of flower is controlled by incomplete dominance. The two alleles are red(R) and white(R'). The heterozygous genotype is expressed as pink.
What is phenotype?
Phenotype is the observable physical properties of an organisms.It includes the organisms appearance, development, and behavior.For example color of a flower, height of plant etc.
What is genotype?
A gene or a set of gene responsible for a particular characteristics is called genotype.In detail it can used to refer to the alleles, or variant forms of a gene, that are carried by an organisms.Example of genotype is AA is a gene that is responsible for black color of hair.
Why other options are incorrect?
Option (A) is incorrect because the RR genotype shows the red flowers.Option (C) is incorrect because the rr genotype shows the white flower.

1. Function
2. Nucleus
3. Mitochondria
4. ATP
5. Chloroplast
6. Glucose
7. Ribosomes
Explanation:
This question is describing the organelles found in a cell. An organelle is a structure that performs a specific FUNCTION (1) in a cell. There are different kinds of organelles with each possessing its own peculiar function. Some of them are as follows:
- NUCLEUS, which is regarded as the brain of a cell because it directs or controls a cell's activities just like the brain of an organism does.
- MITOCHONDRIA is an organelle that produces the energy storing compound called ATP (adenosine triphosphate), hence, it is called power house of the cell.
- CHLOROPLAST is an organelle found in plant cells that functions in the conversion of light energy (from sun) into GLUCOSE (chemical energy) in a process called PHOTOSYNTHESIS.
- RIBOSOMES is an organelle found in both prokaryotic and eukaryotic cells that serves as the site of PROTEIN production in a cell.
