Nutrients cross the membrane wall with the help of protein channels.
Answer:
The hardness rating is 4.
Explanation:
Calcite sits at a hardness rating of 3 and is very easily scratched with a knife and/copper coin. This is where most Marbles, limestones, travertines, rate.
Meanwhile, Fluorite sits at hardness 4 and can be scratched by a knife.
Answer: Neutrophils have a two-lobed or bilobed nucleus, while eosinophils have bean-shaped nucleus and basophils have a multi-lobed nucleus. The lifespan of neutrophils is 5-90 hours, whereas eosinophils lifespan is 8-12 hours and that of basophils have a life span of 60-70 hours. functions- All the granulocytes present in white blood cells play their role in fighting against pathogens and in destroying them, where neutrophils vital role is in engulfing the foreign or toxic particles through phagocytosis; Eosinophils are the first one in triggering the inflammatory response during allergic disorders; and Basophils prevents the immediate blood clotting, as it contains heparin (anticoagulant) in the body. structures- Neutrophils have a two-lobed or bilobed nucleus, while eosinophils have bean-shaped nucleus and basophils have a multi-lobed nucleus. ... Neutrophils make up to 40-75% of the total white blood cells, while eosinophils mark their presence up to 1-6% and basophils are up to 0.5-1% of the whole white blood cells. stained- Neutrophils:Neutrophils are stained in natural pink color. Eosinophils: Eosinophils are stained in brick red in acidic stains. Basophils: Basophils are stained in dark blue in basic stains. counts- Neutrophils are one of the primary types of white blood cells, that evokes the immune response against any foreign particle attack in the body. Eosinophils are another type of white blood cells, that helps in fighting against disease and allergies. Basophils are such white blood cells that help to diagnose the specific health problems like autoimmune disease or other blood disorder, etc. in the body.
Explanation:
The double membrane. It's theorized that chloroplasts used to be their own single-celled organism in the environment (and therefore with its own membrane). Then, the theory states, a larger cell took in the chloroplast by endocytosis, which involves surrounding the chloroplast in the large cell's own membrane. The chloroplast would then have two membranes surrounding it. This is similar to the thinking for mitochondria becoming an organelle as well. Hope this helps! :)
