Answer:

human embryonic stem cells are obtained from embryos, thereby they are subject to ethical, religious, political and legal considerations

Explanation:

Human embryonic stem cells (HESCs) are pluripotent undifferentiated cells derived from blastocyst-stage embryos, which have the ability to produce any type of somatic cells. HESCs are obtained <em>in vitro</em> from embryos that are 5-6 days old. These cells are valuable tools in research in order to understand the genetic and physiological mechanisms of human development, as well as to develop treatments against diseases. The use of embryonic stem cells in research is controversial because these techniques involve the destruction of human embryos, and there are people who consider human life begins with the formation of the diploid zygote after fertilization, thereby raising the debate if a human embryo can be regarded as a human being.

<h2>Answer is "Proteins"</h2>

Explanation:

Proteins are made up of amino acids, or organic compounds, that are linked together through peptide bonds. Different combinations of these amino acids make up all of the proteins from the fibrin that forms scabs on a cut finger to a protein that allows rattle snakes to detect body heat
The human body uses proteins for many things, including repairing and building tissues, acting as enzymes, aiding the immune system, and serving as hormones. Each of these important functions requires a slightly different form of protein. In spite of their differences in structure, all proteins contain the same basic sub-components
Proteins are something that we've heard about because they're an important part of our diet. If we look at this nutrition label for macaroni-and-cheese, we can see that, in addition to containing several grams of carbohydrates and fats, there also contain proteins

the hawaiian islands were formed by volcanic activity, but they are far from any plate boundaries. explain how this could occur.

zhannawk [14.2K]

Answer:

Hotspots from under the ground

Explanation:

There are three different situations where an volcano can form. A divergent boundary, where two tectonic plates move away from each other, subduction boundary, where one of the tectonic plates moves under the other, and a hotspot. Scientists are not completely sure how hotspots form.

The antebrachial region is the forearm. chest area. lower back. area in front of the elbow. bottom of foot.

mylen [45]

The antebrachial region is the forearm.

The antebrachial region is a term used in anatomy to refer to the inner forearm. The forearm refers to the region of the arm which connects the elbow and the wrist.

This region consists of two bones i.e. the ulna (medially) as well as the radius (on the lateral side).

The elbow joint is created by the connection between the trochlea of the humerus and the trochlear notch of the ulna, including the connection between the capitulum of the humerus and the head of the radius.

The medial cutaneous nerve of the forearm, also termed as the medial antebrachial cutaneous nerve, is an offshoot of the medial cord of the brachial plexus.
