Nucleus
Vacuole</span>
Vacuoles<span> are membrane-bound structures found in both animal and plant cells. </span>
They have three important functions in plants -- provide support or rigidity, a storage for nutrients and waste matter until it can be removed, and decompose complex molecules.
Answer:
Protein
Explanation
Ribosome and Rough E.R are organelles in the cell.
E.R are extensive membranes (which are continuous with the nuclear membrane) that exist as flattened compartment in the cytoplasm.These compartment form sacs in the cytoplasm. The sacs are interconnected with one another to form a complete system called the reticulum.
Based on structure two types of E.R exists -the Smooth E.R and the Rough Endoplasmic reticulum.The later is called rough because of Ribosomes attached to its outer membrane. the smooth lacks ribosomes attachment on its outer membrane. Ribosomes are the site of Protein synthesis in the cell.
They are small in number and are made up of RNA and protein.Generally the protein synthesised in the Ribosomes,are moved into the sacs in the R.E.R,where they are modified.They are eventually budded off in vesicles which form the Golgi bodies
Not sure but hope you find it!!!
Answer:
Selection that acts, over evolutionary time, to enhance traits that increase an individual's ability to mate frequently or with quality partners is known as <u>sexual selection.</u>
Explanation:
Sexual selection : The process through which males and females attempt to maximise their chances of reproductive success is called sexual selection. It is a form of natural selection. Charles Darwin suggested sexual selection. Animals compete with others of the same species for the chance to mate.
<u>For example:</u> Male widow-bird grows exceptional long tail feathers, females lack tail feathers.
