What is self esteem?

The term self esteem has to do with the positive feelings that a person have about oneself. There are several reasons why a person could develop a healthy self esteem and many times it could stem from a situation in the life of the person when the person have accomplished something that is monumental or worth while.

Let us take a look at the options that we have in the question. In all of the other cases, we are seeing a person that does not quite meet up with the expectations that the people have. Thus such can not boost the self esteem.

How far along do you have to be to hear a heartbeat?.

Answers

A fetal heartbeat may first be detected by a vaginal ultrasound as early as 5 1/2 to 6 weeks after gestation. That’s when a fetal pole, the first visible sign of a developing embryo, can sometimes be seen.

But between 6 1/2 to 7 weeks after gestation, a heartbeat can be better assessed. That’s when your doctor may schedule your first abdominal or vaginal ultrasound to check for signs of a healthy, developing pregnancy.

How do you think the cells and proteins in your body played a part?

Answers

Answer:

A gene is a segment of a DNA molecule that contains the instructions needed to make a unique protein. All of our cells contain the same DNA molecules, but each cell uses a different combination of genes to build the particular proteins it needs to perform its specialised functions.

Protein synthesis has 2 main stages. The 1st stage is known as transcription, where a messenger molecule (mRNA) is formed. This molecule is transcribed from the DNA molecule and carries a copy of the information needed to make a protein. In the 2nd stage, the mRNA molecule leaves the nucleus for the cytoplasm where the cell’s ribosomes read the information and start to assemble a protein in a process called translation

During translation, the ribosomes read the mRNA sequence of bases 3 at a time. These 3-letter combinations (called codons) each code a particular amino acid. For example, the base sequence TTT codes for the amino acid lysine.

There are 4 bases (adenine, thymine, guanine and cytosine) and therefore 64 (43) possible codons specified using some combination of 3 bases. However, only 20 amino acids are required to build all of the proteins in our bodies (some amino acids are specified by more than 1 codon). It is the particular sequence of amino acids that determines the shape and function of the protein.

Protein synthesis, like many other biological processes, can be affected by environmental factors. These include maternal nutrition, temperaturestress, oxygen levels and exposure to chemicals

Explanation:

Answer:

Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs.
