Changes in the dna are called mutations. They can occur spontaneously. Mutations can only be passed down in gametes--sperm and egg cells. with Darwins theory at mind a mutation needs to pass the test of natural selection to remain in the gene pool. So purposly making mutation or altercations may end in diseases/illnesses or in some cases death because they body can not take it.....hope this helps if it doesnt im sorry!
Earth's crust is generally divided into older, thicker continental crust and younger, denser oceanic crust..The crust is made of solid rocks and minerals.
The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up 84% of Earth's total volume.
The core lies beneath the cool, brittle crust and the mostly-solid mantle. ... Earth's core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle.1
Answer:
The term describes cellular respiration
Explanation:
Cellular respiration, also known as internal or tissue respiration can be represented by the equation:
C6H12O6 + 6H2O ---> 6H2O + 6CO2 + Energy (in form of ATP)
From the equation, glucose from the blood is oxidized by oxygen trapped from the air by the nostrils. The main purpose of cellular respiration is to generate energy required by the body for various life activities
Depending on the model,same gas mileage,no,precisely
In the two-stage cooling method, time allowed to cool food from 135 degrees F or more to 70 degrees F or less can be four to six hours.
