Answer:
Limestones and coal are the types of rocks which are the example of organic type of sedimentary rocks.
Explanation:
These rocks are made from organic compounds that are dead remains of plants and animals. These are also known as fossil fuels. These takes a lot of time to be formed by the pressure of Earth. These rocks do not have much calorific value if they are burnt. Limestone can be used for many purposes like in buildings or any other infrastructure.
Coals are classified as non-renewable source of energy. Non-renewable source of energy is used once and take millions of years to be formed again. This fuels also cause air pollution which is harmful for humans and plants.
Answer:
C
Explanation:
Assume that allele A is the dominant allele that produces the dominant phenotype (tall) in plants that have at least one allele A, and allele a is the recessive allele that produces the recessive phenotype (short) in plants that have two alleles a.
In the parental generation, a true-breeding tall plant has the AA genotype (phenotype: tall), and a true-breeding short plant has the aa genotype (phenotype: short).
We have the Gregor Mendel's cross as in the image attached here.
All of the F1 generation (offspring plants) have the Aa heterozygous genotype, and therefore, they are all tall.
The answer is c (the offspring plants have a genotype that was different from that of both parents).
