Answer:
To swim, they move their tails up and down, rather than back and forth as fishes do. This is because whales evolved from walking land mammals whose backbones did not naturally bend side to side, but up and down.
Explanation:
Answer:
The correct answer will be option-
1. Carbon dioxide concentration
2. Light intensity
Explanation:
A limiting factor is a factor which when present in the limited amount limits the metabolic process.
Photosynthesis is a complex process which converts the light energy to the chemical energy converting the carbon dioxide in the presence of sunlight to useful chemical metabolites like glucose.
The photosynthesis process is limited by the concentration of carbon dioxide and light intensity.
The low concentration of carbon dioxide and low light intensity availability decrease the rate of photosynthesis.
Thus, the selected options are correct.
Answer: The building blocks of proteins are amino acids, which are small organic molecules that consist of carbon atoms linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain.
Translation:
Los componentes básicos de las proteínas son los aminoácidos, que son pequeñas moléculas orgánicas que consisten en átomos de carbono unidos a un grupo amino, un grupo carboxilo, un átomo de hidrógeno y un componente variable llamado cadena lateral.
