Answer:
Focal length is 6.67 cm.
Explanation:
Object distance, u, from the lens = 10 cm
Image distance, v, to the lens = 10 cm + 10 cm
= 20 cm
Apply the lens formula to determine the focal length, f, of the lens.
= 
+ 
= 
+ 
= 
= 
Find the inverse of both sides, so that;
f = 
= 6.67
f = 6.67 cm
The focal length of the lens is 6.67 cm.
The process in which the floors of a building collapse on one another is known as a pancake collapse. This will make the correct answer here B, pancaking.
Answer:
La cromatina
Explanation:
La cromatina es una sustancia dentro de un cromosoma que consta de ADN y proteína. El ADN lleva las instrucciones genéticas de la célula. Las principales proteínas de la cromatina son las histonas, que ayudan a empaquetar el ADN en una forma compacta que encaja en el núcleo celular.
La cromatina es un complejo altamente organizado de ADN y proteínas y es un componente principal del núcleo celular. Las proteínas histonas ayudan a organizar el ADN en unidades estructurales llamadas nucleosomas, que luego se ensamblan en una estructura compacta (cromatina) y, finalmente, en estructuras muy grandes de orden superior (cromosomas).
Answer:
Photosythesis is the process of which plants make oxygen and also gulcose. This process happens when the plants uses their roots to taken in water in the ground and also anchor themselves in the ground. The stomata in the leaves take in carbon dioxide and the sunlight and using theses materials the plants create glucose and oxygen we breath.
