define magnification and cisternae?
Answers
Answer:
Magnification In general terms, it can be said that how big or small the image appears with respect to the object is called magnification of the object.
Explanation:
It is represented as the ratio of the height of the image to the ratio of the height of the object. Magnification is denoted as the letter 'm'.
Magnification is the process of enlarging the apparent size, not physical size, of something. This enlargement is quantified by a calculated number also called "magnification".
A cisterna refers to a flattened membrane disk that makes up the Golgi apparatus. A typical Golgi has multiple stacks of anywhere from 3 to 7 cisternae stacked upon each other like dinner plates.The cisternae also carry structural proteins important for their maintenance as flattened membranes and their stacking upon each other.

if a blue eyed offspring is formed from black eyes parents, what type of character is the blue eye dominant or recessive? expalin with the help of a chart
Answers
Answer:
Blue Eyes Are: Recessive
Explanation:
The brown eye form of the eye colour gene (or allele) is dominant, whereas the blue eye allele is recessive. If both parents have brown eyes yet carry the allele for blue eyes, a quarter of the children will have blue eyes, and three quarters will have brown eyes.

Answers
The process that produces gametes in animals is meiosis.
What is MeiosisMeiosis is a specialized type of cell division that occurs in the reproductive cells, or germ cells, of animals. It involves two rounds of cell division, resulting in the production of four haploid daughter cells, each with half the number of chromosomes as the parent cell.
During meiosis, the genetic material is shuffled and recombined through processes such as crossing over and independent assortment. This genetic variation contributes to the diversity of offspring produced through sexual reproduction.

Cells are regarded as the fundamental units of life in part because they come in discrete and easily identifiable packages.
What are cells?Cells are the fundamental building blocks of all life. Trillions of cells make up the organisms' body.
They support the body's structure, absorb nutrients from food, convert those nutrients into energy, and perform specialized functions.
Nucleic acids, proteins, carbohydrates, and lipids are the four major classes of organic molecules found in all cells.
Cells are regarded as the fundamental units of life in part because they come in discrete and easily identifiable packages.
Like the walls of a house, all cells are surrounded by a structure called the cell membrane, which serves as a clear boundary between the cell's internal and external environments.
