Answer:

(a)

Protoplanets are built up through the collisions of planetesimals over millions of years. The protoplanets orbit stably around the Sun for a while, but eventually they collide with each other. In about 100 million years, several terrestrial planets, like the ones found in our Solar System, are formed.

According to selye's general adaptation syndrome, in which stage do glands throughout the body manufacture different hormones th
vichka [17]
The correct answer is resistance stage.

Hans Selye was a very important endocrinologist working in the field of biological stress. He developed the General Adaptation Syndrome (GAS) which is a model describing an animal's response to stress. GAS is comprised of three stages; the alarm, the resistance and the exhaustion stage.

During the resistance stage, the body's glands produce and secrete several hormones which protect the individual from the perceived stressor. Some of the hormones produced at this stage are the glucocorticoids.

ASAP Please describe the relationship of the organelles of the endomembrane system in a simple manner. Thank you!
elena-14-01-66 [18.8K]
The cell membrane is a phospholipid bilayer membrane that separates the cell from its environment and regulates the transport of molecules and signals into and out of the cell. The nuclear envelope is the membrane around the nucleus of the cell. The nucleus itself is not part of the Endomembrane system. The endoplasmic reticulum is a synthesis and transport organelle that is an extension of the nuclear envelope. The Golgi apparatus acts as the packaging and delivery system for molecules. Lysosomes are the "digestive" units of the cell. They utilize enzymes to break down macromolecules and also act as a waste disposal system. Vacuoles act as storage units in some cells. (Vacuoles do not communicate with the organelles of the endomembrane system and therefore are sometimes not considered part of it.)Vesicles are small membrane-enclosed transport units that can transfer molecules between different compartments. 

Hope this helped
