Answer;
-In the smooth ER
In certain kinds of muscle cells, calcium ions are stored in the smooth ER.
Explanation;
-The smooth endoplasmic reticulum is the part of the endoplasmic reticulum (ER) which does not have ribosomes bound to it, thus not exhibiting the bumpy appearance shown by the rough endoplasmic reticulum.
-The smooth ER is important in the synthesis of lipids, such as cholesterol and phospholipids, which form all the membranes of the organism. In addition it is important for the synthesis and secretion of steroid hormones from cholesterol and other lipid precursors.
Enceladus, one of Saturn's moons of only
about 314 miles in diameter hides in its entrails an ocean of liquid water that
is rich in organic molecules, making it one of the places where it is most
likely to find some form of extraterrestrial life.
Europa is a strange
shaped moon of Jupiter with a large number of intersecting lines. Models
from the interior of Europe show that under a thin crust of 5 km (3 miles) of
water ice, Europa can have oceans with 50 km (30 miles) of depth or more. The
visible marks of Europa could be the result of a global expansion where the
crust could have been fractured, filled with water and frozen.
The correct option is, B, that is, RADIAL SYMMETRY.
Symmetry refers to the balanced distribution of the duplicated body parts or shapes within the body of a living organism. There are different types of symmetry, we have bilateral, radial and asymmetrical symmetry.
Radial symmetry refers to the type of body plan in which the body parts are arranged around a central axis, that is, the body parts are arranged in a circle around an axis.<span />
Answer:
The correct answer is: lets the air get inside the lungs.
Explanation:
The process of ventilation, or breathing, consists of two parts: <u>inhaling and exhaling.</u>
Inhaling is the name of the process that is responsible for the air entering the body by the respiratory tract. Exhaling is the opposite, it lets the air out. Both are equally important since they allow the gas exchange necessary for the oxygenation of the blood.
When inhaling, the diaphragm and the external intercostal muscles contract. This pulls the ribcage upwards and outwards, which increases lung volume while decreasing the air pressure inside.
Answer:
The correct answer to the question: What would happen if the urea were removed after oxidation, would be, C: Disulfide bonds are not positioned correctly unless weak bonding interactions are present.
Explanation:
Christian Anfinsen´s and colleagues´s research on proteins, their structure, their function, and what affects them, yielded information that has impacted the way that proteins are studied today. This research was not only able to find the structure of proteins, but also how this structure was formed, and what would happen if it was affected by different factors, meaning, if the protein would remain functional or not. In his experiment with urea, Anfinsen and his colleagues found that what mattered in protein structure was the fine balance in the elements, called residue, inside the structure, and not those on the outside. They also found that when urea was removed from the protein after oxidation had happened, then the cysteine residue would not be placed correctly inside the structure, thus affecting it and reducing its capacity to perform.
