Answer: Dominance of Gene for Bright Yellow Coloration.
Explanation: Gene carries the genetic makeup of a particular organism. It house all the information of all living organisms.
According to the phenomenon expressed by Gregor Mendel (law of Inheritance), genes are divided into two; dominant and recessive. The gene responsible for bright yellow color is more dominant in ascending generation of the frog which translates that gene responsible for green color is recessive.
Answer:
As we move through the visible spectrum, red to violet (from right to left in the image), the wavelength _____ decreases_____ and the frequency ____________. .
Explanation:
On the right side are the infrared waves and on the left the ultraviolet spectrum
The relationship between wavelength and frequency is inversely proportional (longer, shorter and vice versa)
Answer:
Te correct answer is "Being transported by specific carrier proteins".
Explanation:
Cholesterol is one of the most important lipids in our body. It is useful for membrane formation and for sexual and suprarenal hormone synthesis. The organism obtains cholesterol from food and liver production. It goes to the blood where it is transported by lipoproteins to its final destiny.
In the intestine, cholesterol is absorbed in three phases:
- <em>intraluminal phase</em>: in this phase micellar formation is necessary for cholesterol absorption. Micellar solubilization is a transport way for cholesterol to diffuse through the mucus barrier that covers intestine surface microvilli. Once there cholesterol is available for intestinal cells.
- <em>mucose phase</em>: in this phase cholesterol pass from the lumen to the cytoplasm of the intestinal cells, and when necessary, from the cytoplasm to the intestinal lumen. In the cells´ membrane, there are proteins that transport cholesterol to and from the interior of the cell.
- <em>Intracellular phase</em>: In the intestinal cell cholesterol is sent to the endoplasmic reticulum where it is reesterified to be transported in the blood. As cholesterol is insoluble it is packaged in lipoproteins to be transported.
Each lipoprotein has a union site that is specific for a target membrane receptor. Lipoproteins get in the target cells by endocytosis mediated by the specific receptors. Once in the interior of the cell cholesterol is taken from the lipoprotein by breaking the ester link, and then they reesterify it to include it in the membrane.
A physician who specializes in treatment of the gums is called a periodontist.
Answer:
During mitosis, a parent cells splits into two identical daughter cells.
Explanation:
"a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth."
