Answer:
a. The molecule is not lipid soluble b. The molecule is not derived from a series of steps beginning with cholesterol
Explanation:
All the steroid hormones have a four ring sterol nucleus in their structure. These hormones are soluble in lipids. Steroid hormones are produced by the pathways using cholesterol as the starting substance. Some of the examples of steroid hormones are aldosterone, calcitriol, estrogens, and progesterone. Therefore, if the given molecule is not soluble in lipids and is not derived from cholesterol, it cannot be a steroid hormone.
Answer:
Runoff
Explanation:
The other answers involve the water particles rising to the clouds. So those processes work against gravity and not with it. Runoff uses gravity to flow back into the ocean or large body’s of water.
Mice that are deficient for Apaf1 or caspase-9 are defective for cytochrome dependent apoptosis. Apoptosis is a critical event in development, allowing excess brain cells to be weeded out. The extent of brain overgrowth and the size of the cranial protrusions indicate that the pruning process in the developing brain must be massive. The dramatic effects of the deficiencies of Apaf1 and caspase-9 suggest that the cytochrome c-dependent apoptotic pathway the intrinsic pathway must be critically important in brain development.
It is process of producing female gametes and called creation of ovum

The correct order of structures is mouth, oesophagus, crop, stomach(proventriculus), gizzard, intestine, and anus.
<h3>The digestive tract of birds</h3>
The digestive tract of birds starts from the mouth and ends at the anus.
As the food enters the oesophagus through the mouth, it is pushed down to the first stomach called the proventriculus.
Hydrochloric acid, mucus and a digestive enzyme, pepsin, are secreted by specialized cells in the proventriculus and start the process of breaking down the structure of the food material.
Food substances that are hard to digest are transferred to the gizzard. Nutrients are absorbed in the intestines and undigested food substances are removed through the anus.
