Organelle: a membrane-bound structure in a cell that’s provides a specific function. Examples: mitochondria, chloroplast, nucleus
Cytoskeleton: microfibers found in the cytoplasm of a cell that’s provides shape and structure. Examples: tubules, filaments
Prokaryotic: a cell that lacks a nucleus, simple flagella are described as prokaryotic. Examples: Bacteria and Archaea
Plasmalemma: also called plasma membrane, protects the cell from its surroundings and regulates molecules that travels in and out of cells through channels. Example: plasma membrane, phospholipid bilayer
Dandelion Fluffs are the best adaptation to an area without wildlife.
Answer:
shes wrong
Explanation:
She is wrong, this is because the moon is dark, meaning that the moon would have to be behind Earth and being blocked from sunlight. For example, if the sun is on the left, the Earth in the middle, the moon would have to be on the right, behind Earth. The moon is dark because the rays only are able to hit the Earth, due to the moon's position.
hope his helps! :) pls gives brainlyest if thats ok with u ! :)
Two people carrying the B,b gene/those who have brown eyes and carry the blue eye gene would have to have children to possible produce a child with blue eyes. There is a 25% chance of a blue eyed child in this case.
The terms chromosome and gene were used long before biologists really understood what these structures were. When the Austrian monk and biologist Gregor Mendel (1822–1884) developed the basic ideas of heredity, he assumed that genetic traits were somehow transmitted from parents to offspring in some kind of tiny "package." That package was later given the name "gene." When the term was first suggested, no one had any idea as to what a gene might look like. The term was used simply to convey the idea that traits are transmitted from one generation to the next in certain discrete units.

The term "chromosome" was first suggested in 1888 by the German anatomist Heinrich Wilhelm Gottfried von Waldeyer-Hartz (1836–1921). Waldeyer-Hartz used the term to describe certain structures that form during the process of cell division (reproduction).
One of the greatest breakthroughs in the history of biology occurred in 1953 when American biologist James Watson (1928– ) and English chemist Francis Crick (1916– ) discovered the chemical structure of a class of compounds known as deoxyribonucleic acids (DNA). The Watson and Crick discovery made it possible to express biological concepts (such as the gene) and structures (such as the chromosome) in concrete chemical terms.
