Answer:

1. sympathetic

2. parasympathetic

Explanation:

The sympathetic division of the autonomic nervous system triggers the release of stress hormones from adrenal medulla under emergency conditions. There is a series of physiological responses such as increased heart and breathing rate, an increased flow of blood to skeletal muscles, dilation of pupils, etc. These events helped Nasim to fight the stress conditions.  

Once she was relieved, the parasympathetic system is activated that shut down the physiological responses generated by sympathetic division. It slows down the breathing and heart rate and triggers the digestion and absorption of nutrients to restore the energy level of cells.

what makes up cell membranes and is used to create hormones?(1 point) glucose glucose cholesterol cholesterol starch starch hydr
RUDIKE [14]

Cholesterol makes up cell membranes and is used to create hormones.

Cell membranes are the outer covering of the cell that protect it from the outer environment. A cell membrane is a bilayer of lipid, composed of protein and cholesterol as well. The cholesterol is essential to maintain the proper integrity of the cell membrane.

Hormones are the chemical messengers that are released at one site and they perform their function at another location of the body. Hormones can be made up of several macromolecules like polypeptides, amine acids or cholesterol. The example of hormones made up of cholesterol are: glucocorticoids, mineralocorticoids, and sex hormones.

Biological evidence of the age of the earth includes _____.
kobusy [5.1K]

Answer;

-Fossil evidence

-Comparative anatomy

-Molecular clocks

Biological evidence of the age of the earth includes fossil evidence, comparative anatomy, and molecular clocks.

Explanation;

-Fossils are critical tools in science because they give us clues to the types of plants and animals that lived on Earth in the past.There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined.

-Comparative anatomy is an important tool that helps determine evolutionary relationships between organisms and whether or not they share common ancestors. However, it is also important evidence for evolution. Anatomical similarities between organisms support the idea that these organisms evolved from a common ancestor.

-Scientists can use relaxed-clock methods to deal with variation in the rate of the molecular clock. By measuring the patterns of evolutionary rate variation among organisms, they can also gain valuable insight into the biological processes that determine how quickly the molecular clock ticks.
