An atom of nitrogen would contain 7 neutrons
all of the above are different kinds of enzymes
Answer:
C) decreased functional reserve
Explanation:
Ageing is a biological process which leads to the loss of function of the tissue and cells of the organism.
The biological ageing is determined genetically and can be correlated with the chronological ageing. The ageing is also influenced by the environmental factors which could interfere with the physiology, anatomy and morphology of the organisms.
The cell division cycle gets arrested to prevent the proliferation of these damaged cells and to remove the harmful factors from the body. This leads to the loss of function of the cells and tissues.
Thus, Option-C is the correct answer.
Answer:
The correct answer is -
anemia- erythrocytes
easy bleeding- platelets
Repeated infections - leucocytes
enlarged lymph nodes- leucocytes
shortness of breath- erythrocytes
excessive bruising- Platelets
Explanation:
Cancer of the lymphocytes is chronic lymphocytic leukemia (CLL). Lymphocytes are a type of white blood cell involved in the body's immune system.
Platelets are tiny blood cell fragments that help your body form clots to stop bleeding. The platelets then rush to the site of damage and form a plug, or clot, to repair the damage.
Erythrocytes are red blood cells that travel in the blood. They carry oxygen from the lungs to the body and bring carbon dioxide back to the lungs to be expelled.
Leucocytes- White blood cells (also called leukocytes or leucocytes and abbreviated as WBCs) are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders.
Meiosis is the process that occurs in sexually reproducing organisms in the sex cells of male and female organisms.
Variation occurs in an organism due to the process of crossing over which only occurs in meiosis in which the chromosomes between non-sister chromatids exchanged. Meiosis also causes genetic variation due to the process of recombination so in inheritance, meiosis has great importance and impact on the shape and structure of organism.
