Answer:
In uranium-lead dating, for instance, the radioactive decay of uranium into lead proceeds at a reliable rate. Based on the very old zircon rock from Australia we know that the Earth is at least 4.374 billion years old.
And that's how after rounding we know that earth is 4.5 years old.
Answer:
Murine fibroblasts
Explanation:
Fibroblasts are the most common cellular type in the connective tissue of mammals and immortal murine fibroblasts are often used in molecular biology to study different characteristics such as, for example, to understand the tissue repair processes
Chloroplasts is to conduct photosynthesis mitochondria is mostly the energy
Energy is required for a variety of life processes including growth and reproduction, movement, transport of certain materials across cell membrane.
Fungal Parasites,
specifically basidiomycetes causes various infectious diseases that destroys
billions of dollars of food crops annually with worldwide impact. The 1972 U.S.
corn crop was almost completely destroyed by a fungus and during the late 1990s
most wheat fields in Arizona had to be devastated due to the existence of
fungal parasites. This clearly suggest that the presence of fungal
parasites resulted in loss or reduction of food crops.
Furthermore, basidiomycetes are
called club fungi, which is part of a <span>major group of fungi that produce a basidium
structure that includes mushrooms and toadstools. Although, they have economic
use in pharmaceutical industry such as producing penicillin and provide us food
like cheese, mushroom, in baking and in brewing, there negative impact must
also be consider and should be handle appropriately to eradicate crop
destruction.</span>
