As it travels, it slowly spreads apart until it is hardly visible.
Answer:
There are many different ways that cells can connect to each other. The three main ways for cells to connect with each other are: gap junctions, tight junctions, and desmosomes.
Explanation:
Cell Signaling is an important facet of biological life. It allows cells to perceive and respond to the extracellular environment allowing development, growth, immunity, etc. Additionally, errors in cell signaling may result in cancer growth, diabetes.
"it is needed to ensure that equal 3-carbon units can be made."
One important part of the glycolysis is the metabolization of two three-carbon molecules. A glucose molecule could not be divided into two molecules. <span>
After a phosphorylation of the fructose, the molecule has now two phosphate groups. The molecule is then divided into two and the glyceraldehyde-3-phosphate (one of two) continues the chain reactions of glycolysis.</span>
Note about the question:
In the GIZMO program, you will be provided with 46 chromosomes that are not paired nor in order (box superior-right). According to the chromosome image shown below, you need to look for the correct chromosomes, pair them with their homologous, and place them in their correct spot to complete the karyotype.
Answer:
- Subject B sex: Female
- Justification: The last pair of chromosomes are equally large, meaning that they are two X chromosomes (XX).
Explanation:
<em>Note: You will find the complete karyotype in the attached files.</em>
A human cell has 46 chromosomes or 23 pairs of homologous chromosomes. 22 of them are somatic chromosomes or not-sex chromosomes. The last pair, number 23, is the only sex pair.
To know if an individual is a male or a female, you just need to see the last pair of chromosomes. Pair 23 is the sex pair.
- Male: The pair is formed of a short chromosome (which corresponds to Y from the male parent) and a large chromosome (which corresponds to X from the female parent)---> XY
- Female: The pair is formed of two equally large chromosomes. Each of them corresponds to X, one from the male parent and the other from the female parent). ----> XX
Hydrophilic (water-loving) or could be called water, it mean attracting water molecules as close as possible, the phospholipid is made up of a head that is polar, and a tail that is non polar or in another words called “hydrophobic” , this means that the head of the phospholipid is attracted to water molecules ( this helps you understand the structure of cell membrane formation). Steriod, a class of lipids, some hormones like cholesterol are made up of steroids. They maintain fluidity of cell membrane. Example: oestrogens
