Answer:
The answer is B. Alarm, resistance, exhaustion.
Explanation:
The three are the stages describing the physiological changes the body passes through when under stress.
Alarm stage is the fight or flight stage and heart sends more blood to the part of the body for fighting or fleeing.
Resistance is an alert stage where the bodily functions are going back to pre-stress levels.
Exhaustion is a stage of prolonged stress which can result in the draining of the mental, emotional and physical resources.

e- eukaryote
2. d
Answer:
Eukaryote refers to any of the single-celled or multicellular organisms whose cell contains a distinct, membrane-bound nucleus. Organisms such as animals, plants, fungi, and protists are examples of eukaryotes because their cells are organized into compartmentalized structures called organelles, such as the nucleus
Eucariota se refiere a cualquiera de los organismos unicelulares o multicelulares cuya célula contiene un núcleo distinto, unido a la membrana. Organismos como animales, plantas, hongos y protistas son ejemplos de eucariotas porque sus células están organizadas en estructuras compartimentadas llamadas orgánulos, como el núcleo.

Answer:
The environment is responsible for generating different phenotype from same genotype.
Explanation:
The genotype is set of genes. The genes are present on DNA and are responsible for particular character. The phenotype is observable character produced from genotype. The mutation allows the changes in the genotype.
The same genotype shows various phenotype when it is exposed to different environment.
Answer:
The correct answer will be option-C.
Explanation:
The Nucleic acids present in the cells are of two types: Ribonucleic acid (RNA) and the Deoxyribose nucleic acid (DNA).
These nucleic acids show distinctive differences in their structure like:
1. Sugar: The sugar in DNA lacks oxygen group at the 2' C which is present in the RNA as OH group is present.
2. Nitrogenous bases: The nitrogenous base in the DNA are adenine, guanine, cytosine and thymine whereas RNA lacks thymine and have uracil.
The main difference is the structure if sugar on the basis o which these nucleic acids have been named. Thus, Option-C is the correct answer.
