4 0

Answer:

The increasing amounts of oxygen in earth atmosphere allow more growth of blue green algae.

Oxygen is present about 21 % in the earth atmosphere. Oxygen is important for the survival of living organisms because every living cell needs oxygen for respiration. In respiration, food molecules are broken down to produce energy with the help of oxygen. This energy is used by the cell in different processes.

Why does a clam shell have a good possibility of being preserved? because it is alive because it is dead because it is a hard bo
Juli2301 [7.4K]

Answer:

The correct option is C, a clam shell have a good possibility of being preserved because it has a hard body.

Explanation:

In evolutionary studies, preservation are made in the form of fossils or remnants.

For an organism to be preserved, it must not decay early and it should be hard enough. When an organism is buried quickly then it will take more time to decay and hence will have more chances to be preserved.

As the clam shells are hard so this quality makes them ideal enough to be preserved.

Why did scientists many years ago believe that protein was the storage molecule for genetic information, instead of DNA?
Neporo4naja [7]

Answer:

Many years ago scientists believed that protein, DNA is not the genetic material because of many reasons like DNA is made up of only four type of nucleotides while proteins are made up of 20 different types of amino acids. So the building blocks of protein are way high than DNA.

Most of the cellular function is performed by proteins, not DNA. The three-dimensional shape of protein is much higher than nucleic acid. So as protein heterogeneity was high therefore it was considered as a molecule of genetic information instead of DNA.
