Gibraltar apes have brown eyes (B) that are dominant over blue eyes (b) and long arms (L) are dominant over short arms (l); but some of the offspring of a certain cross have the genotypes bbLl and Bbll in the ratio of 1:1. a) What are the genotypes and phenotypes of the parents

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers

here is the answer

water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. weathering is the breaking down or dissolving of rocks and minerals on earths surface. once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.
