The one-cell zygote, traveling slowly down the fallopian tube towards the uterus, begins to duplicate and multiply. At about the eight-cell stage, the process of differentiation begins, early cells take on distinct characteristics and move toward particular locations, foreshadowing the types of cells they will become. These early cells, capable of becoming any part of an organism, are known as:_______.

Answers

Answer:

Embryonic Stem cell

Explanation:

Stem cells are the multipotent cell which can give rise to a variety of other cells and can form different tissues. The stem cells are present in the embryo and the well-developed adult organism, therefore, is known as the embryonic stem cell and the adult stem cell.

In the given case, after the blastocyst stage of embryo is formed, the cells present in the inner side of the blastocyst possess the ability to form different organs and therefore are called embryonic stem cells.

Thus, embryonic stem cell is correct

What would happen if there were no enzymes in the human body? Explain your answer.

Answers

Enzymes are in our bodies to speed up reactions etc. If there were no enzymes, then our bodies would act very slowly to reactions.

Final answer:

Without enzymes, the body couldn't perform essential chemical reactions quickly enough to sustain life. Enzymes also aid digestion and help in immune defence. Their absence would critically interrupt bodily functions and overall health.

Explanation:

If there were no enzymes in the human body, many essential biological processes would be negatively impacted. Enzymes act as biological catalysts, speeding up the chemical reactions that occur within cells, thereby allowing life-sustaining processes to occur at the rate necessary for life. If we didn't have enzymes, these reactions would happen too slowly to sustain life, or might not happen at all.

Enzymes are vital in breaking down food and converting it into usable energy. Without enzymes, our digestive system would not be able to efficiently break down nutrients, leading to malnutrition and energy deficiency. Moreover, enzymes are involved in the immune system's defence mechanisms. They assist in the destruction of foreign pathogens, thus protecting the body from infections.

Furthermore, each cell's enzyme demand changes according to its needs and role within the body. For instance, the enzymes necessary in stomach cells differ from those in skin, blood, or nerve cells reflecting the diverse functions enzymes perform in the human body.

Overall, without enzymes, the human body would be unable to function properly. They are essential for our survival, and their absence would dramatically alter the way our bodily systems operate.

Arrange the steps for measuring heart rate in the correct order from start to finish. a. Make a fist. b. Feel a pulse. c. Count for 10 seconds. d. Find a radial artery. e. Multiply by six.

Answers

A usual heart rate in case of adults varies from 60 to 100 beats per minute. Usually, a lower heart rate at rest signifies more effective functioning of heart and better cardiovascular fitness. For example, a well-trained athlete may possess a usual resting heart rate closer to 40 beats in a minute.

The following is the correct order to measure the heart rate:

1. Make a fist.

2. Find a radial artery.

3. Feel a pulse.

4. Count for 10 seconds.

5. Multiply by 6.

Determine which strand is transcribed, indicate the polarity of the two DNA strands, and then give the sequence of bases in the resulting mRNA and its polarity.

Answers

A strand that is transcribed is called a template strand, the other one is called a coding strand. The template strand is in 3'-5' direction, and the coding strand is in 5'-3' direction. mRNA is transcribed from 3'-5' template DNA strand, so it is in 5' to 3' direction. The first codon of mRNA is called start codon and usually it is AUG.

Knowing this, we can answer the questions:

The transcribed strand must contain three nucleotide sequence complementary to AUG codon. According to the base pairing rules, it must be TAC. The strand that contains TAC, and, thus, is transcribed is
C C C T A C G C C T T T C A G G T T.
This template strand is in 3'-5' direction and the other one is 5'-3'.
mRNA transcription begins from the DNA sequence complementary to AUG codon:
DNA sequence: 3' C C C T A C G C C T T T C A G G T T 5'
mRNA sequence: 5' A U G C G G A A A G U C C A A 3'
mRNA sequence is in 5'-3' direction.
