Human embryonic development is the development and formation of the human embryo. It is characterized by the process of cell division and cellular differentiation of the embryo that occurs during the early stages of development. In biological terms, the development of the human body entails growth from a one-celled zygote to an adult human being. Choose ALL of the statements that correctly describe stages in human embryology and gestation.
The normal period of gestation is about 40 weeks.
The germinal stage refers to the time from fertilization through the development of the early embryo until implantation is completed in the uterus in about 21 days.
The stages of human development include, in order: zygote, blastocyst, embryo, and fetus
A blastocyst, if untouched and allowed to remain implanted, will eventually develop into a morula.
Changes to the form of the embryo come from differentiation and growth.
The statements that correctly describe gestation are: the normal period of gestation is about 40 weeks; the stages of this process include: zygote, blastocyst, embryo, and fetus; and changes to the form of the embryo come from differentiation and growth.
The gestation period in humans lasts about 40 weeks and comprises different stages and processes from conception until birth. The main stages of this process include:
Zygote: Fertilized ovum.Blastocyst: Cluster of cells that is the result of the zygote going through cell division.Embryo: Unborn human that is still developing, usually before the 8th week of gestation.Fetus: Unborn human in development after the 8th week of gestation.Moreover, this process implies differentiation as cells specialize for specific functions, for example, muscle cells or nerve cells, and growth as the number of cells increases and therefore the embryo or fetus increases in size.

Answer:
Many different types of cells make up the human body. Therefore, it is important for cells to differentiate to form different types of tissue. The tissue can then combine to form different organs and systems that carry out specialized functions for the human body.

Path-breaking medical procedures have begun to pay attention to how microscopic entities aid or hinder bodily health. For example, fecal transplants have helped cure chronic digestive ailments of people who have suffered for years. These new procedures treat the body not as a separate, contained biological entity but as a complex: ___________
a. biomedicine.
b. anthrobiotic environment.
c. personal biosystem.
d. human microbiome.
Human microbiome that is as complex entity of all the microorganism found in the entire body structure of all living organism and the exact location where they are found.
Fecal transplants is idea for replenishing of good bacteria in the body due to resistance from prolong use of antibiotics. It is specifically for treatment of resistance of antibiotic therapy due C. difficile colitis.
In patient above 65, infected with C. difficile colitis and with resistance to antibiotic especially oral vancomycin, fecal transplant is applied to effectively cure this.
The transplant is conducted through the Colonoscopy. Where the fecal is discharge into the colon as the Colonoscope is withdrawal from the colon
.
Since natural good bacteria are present in fecal and have no effect on the good bacteria in the body, this procedure increased the total number of bacterial(microbiota),by stabilizing the the microbiome and curing the patients.

What would happen if cytokinesis failed?
The nucleus would never divide, and the new daughter cells would lack a
nucleus and would die.
The cell would be too big and contain more than one nuclei.
The cell would eventually split on its own.
Organisms would not produce more genetic material for each new
daughter cell.
Answer:
The nucleus would never divide, and the new daughter cells would lack a
nucleus and would die.
Explanation:
Cytokinesis is an essential process of cell division, part of the cell cycle. If cytokinesis failed, cells wouldn't be able to reproduce.
What do biologists call the specialized cells in the nervous system that detect heat, pressure, and other environmental stimuli? A. first responders B. mitochondria C. receptors D. organelles
Answer: Receptors.
Explanation: Receptors. Receptors are groups of specialised cells. They detect a change in the environment stimulus. In the nervous system this leads to an electrical impulse being made in response to the stimulus.
Receptors are the specialized cells in the nervous system that detect heat, pressure, and other environmental stimuli.
What are receptors?Receptors are proteins, usually cell surface receptors, which bind to ligands and cause responses in the immune system, including cytokine receptors, growth factor receptors and Fc receptor.
Moreover, receptors are bound up with functions such as cell activation, cell adhesion and signaling pathways. These functions play a role with the help of receptors.
Therefore, cell activation including T cells, dendritic cells, B cells, granulocytes and NK cells, is an important process in innate and adaptive immune system.

Why does a cis fatty acid have a kinked shape?
Answer:
Steric hindrance in the cis orientation causes the chain to take on a more bent shape. Most natural unsaturated fatty acids are in the cis conformation. As can be seen in Figure 2.327, the cis fatty acids have a more of kinked shape, which means they do not pack together as well as the saturated or trans fatty acids
