Answer:
Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere.
Explanation:
The photosphere has a temperature of 5,800 degrees Kelvin. Sunspots have temperatures of about 3,800 degrees K. They look dark only in comparison with the brighter and hotter regions of the photosphere around them.
Sunspots can be very large, up to 50,000 kilometers in diameter. They are caused by interactions with the Sun's magnetic field which are not fully understood. But a sunspot is somewhat like the cap on a soda bottle: shake it up, and you can generate a big eruption. Sunspots occur over regions of intense magnetic activity, and when that energy is released, solar flares and big storms called coronal mass ejections erupt from sunspots.
If each subunit of a hemoglobin protein molecule carries a heme group and a hemoglobin protein molecule is made of four subunits, two α and two β, we can simply multiply four (number of heme groups that can be found in one hemoglobin protein molecule) by three (number of hemoglobin protein molecules considered). 4×3=12
There are twelve heme groups in three hemoglobin protein molecules.
Answer:
A função do citoplasma é fornecer sustentação esquelética para a célula através da estrutura composta por filamentos e túbulos proteicos. Além disso, todo o conjunto de estruturas mergulhadas no citosol apresenta bastante dinamismo, fato que possibilita à célula realizar alguns movimentos.
No citoplasma, ainda há membranas que atuam como verdadeiras usinas intracelulares, que fornecem energia indispensável à manutenção da vida.
Outro fato que você deveria saber sobre o citoplasma é que ele preenche todo o interior das células eucariontes, sendo delimitado pela membrana plasmática. Já nas células procariontes, o citoplasma fica entre a membrana plasmática e o núcleo da célula.
Explanation:
because the doctor might not have studied her enough to diagnosed her
It should be an explanation on what you wanna learn about in the experiment, it should be based on prior knowledge, it is also different from a prediction
