Answer:
Bar and lexical.
Explanation:
Bar and lexical are the name of two different types of scales that are found on maps. Bar scales are used more frequently in the maps because they represent or show the distance ratio visually instead of in words, while on the other hand, lexical scales may be expressed in words, as a ratio, or as a fraction. Examples are 1:10,000 or 1/10,000. Using map scales is very important in the real world if you want to find out the distance you are traveling.
Acetylcholine broken down is the process by which this neurotransmitter activates a suitable ligand-receptor to trigger a cell signaling pathway.
<h3>What is Acetylcholine?</h3>
Acetylcholine is a chemical messenger (i.e., a neurotransmitter) that is used to transmit signals inside the body.
Acetylcholine broken down is due to its hydrolysis, which ends cell signaling between brain synapses.
In conclusion, Acetylcholine broken down is the process by which this neurotransmitter activates a suitable ligand-receptor to trigger a cell signaling pathway.

Answer:
The endometrial lining is shed during menstruation and is then regenerated by the hormone estrogen.
Explanation:
The menstrual cycle can be described in terms of:
1. <u>OVARIAN cycle</u>: divided into
-Follicular phase of variable length lasting between 7 and 21 days.
-Ovulation
-Luteal phase which is fairly constant and lasts between 12 and 16 days.
The most common cycle length is 28 days and this occurs in 15% of women in their reproductive age
.
The duration of flow is between 2-6 days.
2. <u>ENDOMETRIAL cycle</u>: divided into
-Proliferative phase where there is increase in growth of the functional layer and the endometrial glands under the influence of oestrogen.
-Secretory phase where endometrial changes are influenced by progesterone activity.
The endometrium is made up of the basal layer and the functional layer.
The basal layer remains intact throughout the cycle while the functional layer is shed during each menstruation.
