Part 1: The eclipse observed was a lunar eclipse. The sun is usually not visible during these eclipses. The moon is new during a solar, but full during a lunar. It is red during a lunar eclipse due to a reflection of the Suns light behind earth. It happens more often because Earths shadow is larger than the moons. The umbra is larger as well, so it lasts longer than a solar eclipse.
Part 2: The moon is in the full moon phase. The Earth is in between the Moon and the Sun. The umbra of Earths shadow is cast directly on the moon, casting out the suns light. A tint of the reddish color shines around earth from the Sun making the dark moon appear red. The moons axis is slightly tilted , so the umbra does not hit the moon every month. But when it does? It creates a lunar eclipse.
Answer:
Option-A
Explanation:
Penicillin is an antibiotic drug that is derived from the fungal species of Penicillium molds especially the<em> Penicillium notatum</em>. The penicillin acts by disrupting the formation of the cell wall and thus prevents the growth of the bacteria.
The discovery of penicillin was accidental when he was studying the petridish of staphylococcus and he found that due to avoidance while the experiment, molds grew in the petridish. The area around the mold was clear and clear rings without the bacteria were easily observed. This lead to the discovery of the penicillin compound.
Thus, Option-A is the correct answer.
Answer: False
Explanation:
Protozoans are not the organism that fix nitrogen for the plants. The organism that fix nitrogen to convert it into a form which can be used by plants are known as diazotrophs.
These are bacteria and archae that fix nitrogen gas found in the atmosphere into more usable form such as ammonia.
These organism can grow without any external source of fixed nitrogen. Example: Rhizobia and azospirillium.
Bacteria cells, I believe so.
Answer:
Due to genetic defects, a family history of hormone imbalances, or certain diseases.
Explanation:
According to the data, the blood is deficient in hormones which is due to a number of factors such as genetic defects, a family history of hormone imbalances, or certain diseases etc. The normal person has 10-20 units of hormones per ml of blood in their body, if the body has low in hormones the body does not perform its function properly that leads to certain diseases such as obesity, osteoporosis, and cardiovascular disease so we can say that genetic defects, hormone imbalances, or certain diseases are the causes of low in hormones.
