Answer:
A protein molecule present in the RBCs, which helps in the transportation of oxygen from the lungs to the different parts of the body and brings back carbon dioxide, that is, collected from different parts of the body back to the lungs is known as hemoglobin.
The general features of hemoglobin are that it comprises four molecules of protein in the form of globulin chains. In adults, the molecules of hemoglobin comprise two beta-globulin chains and two alpha globulin chains, while in infants and fetuses, the beta chains are least found, and is substituted by two gamma chains.
Each globulin chain comprises an essential iron-containing compound porphyrin, which is termed as heme. Together both iron and heme play an essential role in circulating oxygen and carbon dioxide in the blood. This iron gives the red appearance to the blood.
Because for one plants reproduce a lot more than animals by up to 100 seeds coming from each plant. Also if there were more animals plants would run out.
Answer: The main difference between lymphocytes and phagocytes is that lymphocytes generate specific immune responses against pathogens whereas phagocytes generate the same response to any pathogen. This means lymphocytes are the tools of the adaptive immunity whereas phagocytes are the tools of innate immunity
Explanation:
The pyramid of the biomass depicts the depicts the bio productivity at each level of the organism. The producers are the organism, which have the highest number of the productivity and their number is comparatively higher than the consumers.
In the pyramid of biomass, the herbivore comes after the producers and then the carnivores. In this case, the grass would have highest productivity, so, it would occupy lower most position, then mouse and then snake.
So, the order in a biomass pyramid from lowest to highest is grass, mouse, snake.
Plants are classified as a “kingdom” united by a common characteristics such as, the presence of chloroplasts which enables them to perform photosynthesis, and cell walls made of cellulose.
