Answer:
C: James-Lange Theory of Emotion; B: Cornea
Explanation:
The James-Lange theory of emotion is a theory proposed independently by two (2) psychologists "William James" and "Carl Lange" and it posits that "<em>emotion is equivalent to the range of physiological arousal caused by external events</em>." This means that for someone to experience emotion, he must first be aroused physically evident in ways such as increased respiration, heart-rate etc., and that their interpretation of such physiological excitement is what leads to emotion in people.
B. Cornea
The eye has 3 layers: The outer layer, the middle layer and inner layer. The outer layer is composed of the sclera, cornea and iris. The sclera is the white eye, the cornea is an opaque tissue, sits in front of the eye and it allows light to enter into the iris.
You and use flyers, posters, use social media, make videos, also ask experienced people that are in the same field as you.

As teens move through adolescence,
A. Freedom increases, but so does responsibility.
This is because it is the only answer that makes sense. When you become a teenager, your parents give you more freedom, but it is up to you to make sure that you control this new freedom in a responsible way.
The answer isn't B or D, because freedom increases as you grow older; it doesn't decrease as these answer choices suggest.
The answer isn't C, because as teens move through adolescence, their parent's expectations increase as they give them more freedom.
So, the answer is A.
Answer:
1 .The two properties of glass are transparency, and breakage resistance.
2. The two properties of fiberglass that make it suitable for insulating homes is because it eliminates air movement in the space that it occupies, and also it helps the spread of heat.
Explanation:
Answer:
1. spontaneously
2. resting potential
3. action potentials
4. pacemaker potentials
5. K+
6. Na+
7. into
8. Ca+
Explanation:
Pacemaker cells (also known as sinoatrial node cells) are cells that generate rhythmic impulses and set the pace for blood pumping in the heart. These cells have the ability to rhythmically depolarize and initiate action potentials. In pacemaker cells, Ca2+ and Na+ levels are higher in the extracellular environment, while K+ concentration is higher intracellularly. The pacemaker action potentials have three phases: 1-depolarization, where membrane potential reaches -40 mV and voltage-gated Ca2+ channels open, 2-repolarization, where voltage-gated Ca2+ channels close and voltage-gated K+ channels open, and finally 3-gradual depolarization, which is caused by the slow influx of Na+ ions.
